Earnings data: change or no change?

The CSO have published their latest release of the Earnings Hours and Employment Costs Survey (EHECS). The data give an insight into employment numbers and average earnings across the Irish economy. The survey began in Q1 2008 and replaces a number of sector surveys ran by the CSO.

The simplest comparison is between average weekly earnings in the public and private sectors as shown in the following graph.

The Blame Game

The Consultative Consumer Panel published their Submission on the Performance Review of the Financial Regulator 2008/2009. The 12-page report can be read here. It is a "hard hitting" report but that takes aim at the performance of the Financial Regulator and it's now departed Chief Executive, Pat Neary. Mr. Neary, it seems, is the one to blame for virtually all the ills in the economy. The report states:

The Financial Regulator's failure to ensure sound financial services providers has hurt consumers hard. They have suffered from negative equity on their homes, falling share prices, poorer returns on pension funds and the lack of availability of credit. The cost of bailing out the banking system has contributed to rising unemployment, wage and social welfare cuts and higher tax rates. Those negative effects have been only partially offset by lower mortgage rates, adjusted asset prices and higher deposit rates.
Is your home in negative equity? It's Pat Neary's fault.
Has your investment portfolio or pension fallen in value. It's Pat Neary's fault.
Are you finding it difficult to get a loan. It's Pat Neary's fault.
Have you lost your job? It's Pat Neary's fault.
Has you Social Welfare been cut? It's Pat Neary's fault.

It is clear there was huge problems in the Financial Regulator's office but this 'blame game' or point scoring approach is of little use. Also if you actually look at the points the report makes under it's five key headings it is clear that most have them relate to consumer banking and have little to do with the banking crisis we have now.

The consumer banking sides of our main banks are incredibly healthy. There are some issues with the information provided and 'advice' given to consumers but consumer banking did not lead us into this mess - property development and investment banking did that. What we actually need is not a Consultative Consumer Panel Report but a Consultative Investor Panel Report.

In the first six months of 2009 AIB posted an operating profit of €1.7 billion. For the first half of it's financial year BOI recorded an operating profit of €787 million. These figures are huge relative to the value of the banks.

Looking at yesterday's closing share prices we see that AIB has a market capitalisation of about €1 billion and BOI of about €1.2 billion. If you borrowed to buy these banks you would have the loans paid off with less than 12 months operating profit from the banks and would have essentially gotten the companies for free.

Obviously, these banks have huge problems on their balance sheets with huge amounts of their assets (issued loans) worth only a fraction of their book value. The banks' problems are not on the consumer side. They are on the investor/developer side. This nice little video sums it up but note that it is investment loans that are the main problem in our case.

The banking crisis here is different to that in the US which was primarily caused by sub-prime mortgage lending in the consumer sector. The size of this problem has consequences across the financial world. Here it is explained with champagne flutes so loved by our former banking and property development high-flyers.

The report published by the Consultative Consumer Group is useful but some of their shots go 'out-of'bounds'. Consumers are being hurt by the financial and economic situation as today's figure on mortgage arrears reveal. However, we have got to be careful where we are laying the blame, or more accurately, how we are laying the blame.

Currently 'the only show in town' to find our way out of the banking crisis is the National Asset Management Agency (NAMA). The only loans the NAMA will be looking at are investor/developer loans. The €4.8 billion in residential mortgages in arrears of more than three months or the residential mortgages in negative equity will not be part of the NAMA solution.

The investigation that Prof. Patrick Honohan is calling for into the banking sector in Ireland will be paying little attention to consumer banking, if the type of investigation he is looking for is set up. We got snippets of this in Primetime Investigates on RTE last night.

People respond to incentives - the rubbish edition

RTE report on the move today by Dublin City Council to abolish the waiver of domestic waste charges that was in place for low-income households. These households will still be exempt from playing the standing charge, currently €96 per annum, and will get four free lifts per year but will have to pay a charge when they put out their bin for collection after that.

The charge per lift is €6. The average household not on a waiver puts their bin out 16 times a year. A household that puts their bin out 60% of the time (16 times a year) will incur a charge of €6 x 12 = €72. Why did the Council seek to have this change introduced? City Manager John Tierney provides the answer.
Mr Tierney added that the waiver scheme had not been an incentive to minimise output as those on waivers had been putting out almost double the amount of refuse as other households.
Those that did not have to pay a charge per bin lift put their bin out for 100% of collections (26 times a year). Those that have to a pay a charge per use put their bin out for 60% of collections (16 times a year). More here.

People even respond to rubbish incentives.

Research Report Card

Forfas have recently released a study on the output of Irish researchers called "Research strengths in Ireland: A bibliometric study of the public research base" and can be read here. The press release for the report paints a positive picture.

A comprehensive study of publicly-funded research performance has shown that Ireland has improved in terms of the volume and impact of its research. Ireland ranks 8th on the impact of research publications within a group of 20 comparator countries.

The study was conducted on behalf of Forfás and the Higher Education Authority (HEA) by Evidence Ltd., part of the Thomson Reuters Group. It shows that Ireland is punching above its weight in terms of the impact of its research.

The report goes through output and impact factors in a number of key research areas at both a national and institutional level. Here, we will consider the output and impact of business research in Ireland.

The performance of Ireland in business research is pushed upwards by a jump in 2007 to 123 papers that was well above the 71 paper average of the previous five years. It is not certain that this higher level will be maintained. Even with this increase Ireland still ranks only 17th of the 20th countries included.

Output may be low but the citation impact (measured as citations per paper) seems stronger

Ireland’s ranking within the comparator group has moved up to 5th, but this position reflects other poor performances relative to world average by a number of comparator nations rather than any great strength in Irish research.

Looking at the total number of research papers by institution across all areas.

The three biggest Irish institutions, UCD, TCD and UCC show strong growth in research output over the ten year period. This growth however has not been replicated in the business area in UCC.

[Note: The section of the report that looked at 20 "project" research areas provided research output data for an area called "economics and business". As with the statistics above the section of the report that looks at institutional performance reports statistics for "business". Economics does not seem to form part of the institutional comparisons. The total number of papers in "economics and business" from 2002-2007 was 568 or an average of 95. There were 344 papers included in "business" from 2003-2007 for an average of 69 a year. It is not clear why a "project" research area is larger than a "main" research area or whether Economics forms part of the "business" main research area.]

UCC is the only institution in Ireland that has seen a drop in the output of business papers. For the five year period 2003-2007, UCC's output of business reserach was just 16% of that of UCD. UCC produced an average of 4.6 business research papers per year. For the entire sample UCC produced 5375 papers with only 250 or 4.6% of these in the business area.

UCC is in a group with NUIM, DCU and UL producing about 5 business research papers per year. NUIG, TCD and, in particular, UCD all having higher business research outputs. The report notes that "Business output volume is still very low, with most institutions producing barely a handful of papers per year. TCD is not increasing its output, so the growth at UCD marks it out as the centre for business research rather than just a leader in a more general growth pattern."

The citation impact of UCC business research is extremely low and is by far the worst of the institutions included. The report again emphasises the performance of UCD noting that "UCD is the only institution with significant volume and growth and its impact is now rising above world average. It is notable that TCD has slipped downwards over several years."

UCC is nowhere.

They think it's all over....it is not

The CSO have released the National Accounts for the third quarter of 2009. The figures reveal that seasonally adjusted GDP rose by 0.3% in the quarter and that technically Ireland is now out of recession.

The first issue to note is that these are provisional estimates. When the GDP figure for Q2 was first released in September the published change was zero. The revised figures indicate that GDP in the second quarter GDP fell by 0.6%. The Q3 figure from yesterday may also be revised downwards. Here is a graph of the quarterly GDP figures for the last five years.

Undoubtedly the recession is "bottoming out" but it is still too early to call it over and we still may have a bit of falling to go. Why? All the elements that make up the GDP figure are declining. All that has changed is the relative pace of these declines that gives the anomaly of a GDP increase.

GDP in make up of private consumption expenditure, firm investment expenditure, government expenditure and the balance of exports and imports. We have

GDP = C + I + G + (X - M)

The following table has the quarterly growth rates for the components of GDP for the past four quarters (table taken from here).

All of the components of GDP are falling and all of these declines have accelerated since the second quarter. The reason GDP has risen on aggregate is because this change has been much greater in Imports than in the other sectors. Imports entail sending money abroad to buy goods from abroad and does not add to economic activity or income here. The Irish economy did not grow in the last quarter, we simply sent less of our money abroad to buy foreign goods. In fact the aggregate of C + I + G (if Ireland was a "closed economy) declined by 2.6% quarter on quarter.

Looking at the GDP figures by sector we do not see much upswing. Click to enlarge.

A minor increase in Transportable Goods Industries and Utilities aside, the trend in most sectors is still downward. There were quarterly decreases in Agriculture, Construction, Transport and Communications, Public Administration and Other Services.

Of course, if you want a measure of national income in Ireland GDP is not appropriate. GNP which takes account of net factor income from abroad is a far better measure. How did that do in the last quarter? Down 1.4% and is now down in eight of the last ten quarters including the last six in a row.

Home and Away

The CSO has just released the 2009 Q3 results from the Quarterly National Household Survey (QNHS). This is one of the most important sources of information produced by the CSO and contains much interesting information.

One thing we can learn from the QNHS is the estimated number of foreign nationals (or in the unfortunate vernacular non-nationals) in the labour force. The following graph tracks the number of foreign nationals that are employed and unemployed for six years from the third quarter of 2004. Click graphs to enlarge.

The number of non-Irish nationals in the labour force rose by about 125% from 160k to 365k between 2004 and the end of 2007. Since then the number has fallen back to 317k and continues to trend downward. The numbers unemployed remained below 30k until the middle of 2008 but there are now an estimated 55k non-Irish nationals unemployed.

This 25k increase in unemployment contrasts to the reduction in employment among non-nationals of about 80k from its peak. Approximately two-thirds of non-nationals who have lost their job have left the country. This means that the deterioration of labour market conditions in Ireland is actually worse than that indicated by the unemployment data.

The trend of non-nationals as a proportion of the labour force follows a similar pattern to totals.

At the peak over 16% or one out of every six workers in the Irish Labour Force was a non-Irish national. This is now down to one in seven and the current downward trend will bring it back towards the one in 12 seen at the start of the series in 2004.

If we look at the origin of these workers we see a clear pattern emerging. The number of workers from the UK and EU15 countries in Ireland has been fairly constant over the past six years. There has been some increase in non-EU workers coming to Ireland but the most substantial increase has been in workers from the "EU Accession States" in Eastern Europe.

There has been an average of about 55k workers from the UK and 33k workers from the rest of the EU in Ireland over the past few years. These numbers have been relatively stable. The main increase has been among EU15-EU27 countries. At its peak there was in increase of over 400% in the numbers of workers from these countries with an increase from 35k to 180k. The downward trend over the last two years has seen this drop back to 152k. The increase and drop in workers from non-EU countries is, as would be expected, not as pronounced and there was actually an increase in the last quarter.

If we move from labour force totals to unemployment rates we see that unemployment among non-Irish nationals has been consistently higher than the unemployment rate among Irish nationals.

For most of the graph this difference hovered between 1.5 and 2.5 percentage points but there is now a 5.3 percentage point difference in the unemployment rates between the two groups. Looking at the unemployment rates by origin of work we see

The lowest unemployment rate is among workers from the EU15 at only 7.8%. Unemployment among workers from the EU Accession States is highest with 19.5% of workers from these countries now unemployed.

Reinventing the market for GPs

In his excellent 2002 book, Reinventing The Bazaar, the late John McMillan described how the workable platform for markets has five elements:
  1. Information flows smoothly
  2. Property rights are protected
  3. People can be trusted to live up to their promises
  4. Side effects on third parties are curtailed and
  5. And competition is fostered.

McMillan describes how these platforms aid the effective operation of markets. He also outlined situations in which suitable government intervention can help if the effectiveness of one or more of these platforms are absent. The market for health needs intervention on many many grounds but too often the cure is worse than the disease.

Three of the key pieces of information consumers need to help them are availability, price and quality. There are a huge number of examples of producers trying to conceal this information for their betterment.

The GP market in Ireland is one that has been traditionally characterised by a lack of information. This strategy is part of the practice and ethical guide that the Irish Medical Council issues to GPs. The 2004 edition of the guide required that new GPs could only use newspaper announcements (not advertisements) when opening a practice. All other forms of advertising was prohibited. All internet material must be "non-promotional" and the most suitable place to display prices was inside the practice. Price or product advertising was not allowed. (See sections 6 and  7, pages 20 and 21.)

According to The Competition Authority the effect of these restriction has been to
  • Create barriers which unnecessarily inhibited GPs becoming established.
  • Favour established GPs.
  • Reduce the incentives for innovation on the part of GPs
  • Discouraged price competition in the case of private patients.
  • Make it difficult for consumers to obtain information on the availability of medical services in their area.
If we just consider the effect of the ban on price advertising. A lack of price information means that the consumer must incur search costs to determine the information. It can be shown that in the presence of search costs the equilibrium price in an otherwise competitive market will be the monopoly price. This is the basis of the tourist trap model.

It is in GPs' interests to keep price information from consumers as it increases their profits. It may have been working as this graph from the report by The Competition Authority indicates. Click to enlarge.

Following the concerns raised by The Competition Authority the 2009 edition of the Medical Council guife for GPs removes the formal ban on price advertising and no longer states that prices can only be displayed in the practice (see Section 5.4 page 49).

Along with the recently introduced 50c prescription charge, this attempt to get information flowing more smoothly in the GP market sees increased attempts by government to harness market forces in the market for health rather than suppress them. This is smart.

Fergus and Fintan

The opinion pages of today's Irish Times and Irish Examiner have two similarly themed pieces on how last week's budget shows that the government is engaged in a "war on the poor".

In his Irish Times piece Fintan O'Toole writes:
...the Economic and Social Research Institute produced stark new figures on tax relief for private pensions. It showed that €8 out of every €10 goes to the top 20 per cent of earners. It also showed that giving this relief at the standard rate of tax (which is to say, making it available on an equal basis to all taxpayers) would raise revenue of €1 billion a year – significantly more than the savings made by cutting social welfare payments. More than four-fifths of this money would have come from the richest 20 per cent.
In the Irish Examiner Fergus Finlay concludes:
This is the first time ever that a country has decided that the poor must pay our debts. In all the years of the Celtic Tiger, the gap between rich and poor in Ireland never narrowed. That’s because when the going was good, all the tax breaks were given to people who had plenty. Dozens of tax breaks, year after year. But now we’re in deep trouble and our best response, uniquely in the world, is to target people who have nothing. Being Irish will never feel the same again.
Both writers are displaying an alarming ignorance of how the Irish tax system, or any tax system, actually works. The Revenue Commissioners Statistical Reports provide income distribution and tax burden data for the Irish workforce. The most recent report is for 2008 and the income distribution data for the year 2006 are available here. Ronan Lyons uses the data on page 6 to produce this graph. Click to enlarge.

The horizontal axis gives incomes in €000s and the vertical axis gives the average tax rate. The tax rate does not go above 10% until income gets to about €40,000. What we also need to consider is how many people are in each income category.

Of the 2.25 million cases the Revenue have, nearly 72% have a gross income of less than €40,000. These 72% of earners received 40% of the total income reported. They paid only 12% of the total income tax collected and had an average tax rate of 5.1%.

The 40% of cases who earned less than €20,000 paid 0.62% of the total income tax collected and had an average tax rate of 0.84%. The average amount of income tax paid by the cases in this bracket was €82.60 - for the year!

Yes Fergus and Fintan you are right - the poor do not get tax breaks. But in your rush to produce some good copy you ignore the fact that we do much,much more for them. Whatever money they earn we let them keep. All of it!

The poor do not get income tax breaks in this country because the poor do not pay income tax. You cannot get a tax break if you don't pay tax in the first place.

Fintan and Fergus have noble and valid aspirations, and are right to promote the needs of the poor. It's a pity that their arguments are so flimsy.

For a primer they can read the parable of how the tax system works.

Tax something and you get less of it

The only certain things in life may be death and taxes. In Economics we are certain that people respond to incentives, just not always in ways predicted. This gives rise to The Theory of Unintended Consequences. It's just a theory but the evidence to support it is manifold. [Aside: A super little example can be seen in this report on attempts to preserve fish stocks in the Pacific.]

Anyway back to the taxes. Last week the Chancellor of the Exchequer in the UK, Alastair Darling, announced a super-tax on bankers' bonuses of 50% on all bonus payments above £25,000. This tax was targeted at those who had allegedly caused the finanical crisis and to offset the "bailouts" given to the financial sector.

In this instance a quick look at the incentives should clearly lead to the unintended consequence of this action. Rather than pay the tax, financial firms and their employees will just leave. It seems this may already be happening. Sky News' Business Report Mark Kleinman reports:
I have learned that Tullett Prebon, one of the largest independent financial trading firms in London, is offering its employees the chance to relocate to its offices in Switzerland, Bahrain and Singapore as a result of the uncertainty caused by last week's Pre-Budget Report (PBR).

Whether they will actually move is debateable. And also, it is actually too late for Tullett Prebon's employees to avoid the once-off super tax for this year, as the BBC report. However in an email to staff last week, the Chief Executive of Tullett Prebon (a company which received no "bailout" money), Terry Smith said:

"It is not clear how if at all the Chancellor's announcement yesterday will affect us, but his proposals regarding the way that bonuses are to be treated this financial year, coupled with the explicit refusal to guarantee that similar "one off" taxes will not be imposed next year and in subsequent years, has caused a number of you to once again raise the matter of relocation out of the United Kingdom."

The uncertainty alone may cause some employees to move to Tullet Prebon's offices in Switzerland, Bahrain or Singapore.

Alastair, my darling, surely you know that a bit of something is better than a lot of nothing.

Getting smarter?

In last week's Budget Brian Linehan formally introduced the 50c per medical prescription for medical card holders that had been flagged over the previous few weeks. It seems we are taking at least one leaf out of the Singapore book. Well a bit of a leaf anyway. Singapore combines government subsidies with patient co-payment for virtually all medical care.

When a consumer is insulated from cost they have no incentive to weigh up the costs and benefits of a decision. Once the costs are zero any benefit (or even a perceived possible) benefit will encourage over-utilisation. This is what has happened when medical prescriptions have been free with people collecting the prescription even if they didn't actually need it. In a letter to The Irish Independent one person wrote.
As a public health nurse visiting homes on a daily basis, it is astonishing to note the vast amounts of excess and unnecessary medication which accumulates in people's homes.
There is also other anecdotal evidence of the families of recently deceased relatives returning thousands of euro worth of prescribed medicine to the HSE that had been collected but never used, simply because there was a prescription for it. As the HSE can not vouch for the medicine it must be destroyed. The above letter continues

Despite the fact that many monthly prescriptions are not used in their entirety, and despite both patient and pharmacist being alerted to this, the system allows the entire monthly prescription to be reissued regardless. There is little or no appreciation or consideration of the cost, particularly as this flawed system is paid for by the taxpayer, who, by the way, is not entitled to free medical care or medications.

Many years go when I lived and worked in the UK, a charge was payable for each prescription. The busy GP might have been quick to issue the prescription but I had a little more time to consider if the purchase was essential enough for me to hand out the charge rather than the easier option of obtaining the item, knowing someone else was paying for it. The 50c per item fee is negligible and will go some way to reducing the vast mount of unnecessary prescribing and waste.

This public health nurse would make a fine economist.

We are finally cottoning on to the idea that anything free will be over-utilised. And that even a small charge can have a big impact. The blight of plastic bags was "cured" when a small charge was introduced that made people consider whether it was actually worth using a plastic bag to home a pint of milk and a packet of biscuits. When A&E visits were free (in money terms) many patients who should have gone to their GP made unnecessary trips to an Accident and Emergency Departments in situations that were neither an accident or an emergency.

Of course, the issue of setting the appropriate charge remains. The plastic bag levy began at 15c in 2002 and is due to be increased to 44c next year. A&E charges currently stand at €100 compared to an average of €60 for a visit to the GP.

Replacement Rates, Unemployment and Poverty Traps

On the 4th of December the Department of Finance published a short report on Replacement Rates and Unemployment. The six-page document can be accessed here.

What are Replacement Rates?
The replacement rate for given income levels measures the proportion of out-of-work benefits received when unemployed against take home pay if in work. While there is no pre-determined level of replacement rate which would influence every individual’s decision to work, clearly the higher the replacement rate, the lower the incentive to work. A replacement rate in excess of 70% is considered to be excessive.
Thus it is a measure of how much of a person's family income would be replaced if they were to lose their job/income and start receiving social welfare. Why they are of concern in Ireland is nice captured in this letter which appeared in The Irish Independent back in April. Andy's friend may be imaginary but the general argument is true.

High replacement rates lead to Unemployment Traps which occur

"when a person’s out-of-work family disposable income compares favourably with his/her in-work family disposable income, thereby resulting in disincentives to work.
A related problem are Poverty Traps which occur
"for those in employment when an increase in an employed person’s gross income results in a reduction in net income, thereby resulting in disincentives to work for higher earnings or work for increased hours. This can arise because of a move into a higher tax bracket or because of withdrawal of social benefits as gross income crosses certain thresholds."

The Department produces replacement rates for three income levels

  1. The national minimum wage (NMW) = €17,542
  2. 67% of the average industrial earnings (AIE) = €22,535
  3. The average industrial earnings (AIE) = €33,634

and they are reproduced in the following table.


  • Single people with no children (28% of Live Register cases) face high replacement rates at the national minimum wage, although below 70%. Replacement rates are not an issue for higher earning single people.
  • Couples with no children where both are not working (10% of Live Register) face high replacement rates at each income level up to AIE, though these are under 70% except at NMW.
  • Couples with one or two children where both are not working (5% of Live Register)have higher replacement rates again. These are 70% and above for couples with one or two children who would earn at two thirds AIE (c. €22,500) or less.
  • One-Parent Families (29% of Live Register cases) have low replacement rates except where out-of-work income is supplemented by Community Employment Scheme (CES) earnings.
  • There are significant welfare benefits for couples for one working at NMW or two thirds AIE; as the other spouse can claim entitlement to means tested JA.
  • Rent supplement has the potential to introduce significant disincentives to work and is received by 12% of cases on the Live Register.

For example, of couple claimants in receipt of rent supplement 43% have no children and they could face replacement rates as high as 102% if the maximum rate of rent supplement (based on Dublin rates for a couple with no children) was paid out-of-work and no rent supplement paid while in-work, i.e. they would have a higher family income if they remain out-of-work!


People respond to incentives - the science cheat edition

As we well know all of economics can be summarised by just four words - "people respond to incentives" - the rest is commentary.

Thierry Henry handled the ball because the benefits of cheating were greater than the cost. What incentives can we find that underlie the academic and scientific fraud that has taken place at the Climatic Research Unit in the University of East Anglia for at least ten years?

A quick check of this spreadsheet reveals some of the answers. Click it and see where the money to keep Phil Jones and his buddies happily engaged in fraud in the CRU has come from.

The file reveals details of 53 projects in with Prof Phil Jones is the sole or a joint PI (principlal investigator). The 53 projects see Jones allocated £13.7million pounds at an average of just over £250,000 per approved grant application. That is a lot of money to be playing around with.

Where did this pocket money come from? Prof Jones and his cronies are hugely grateful to the taxpayers of the UK, the US and the EU for funding as they have received grant after grant from the UK Met Office, the US Department of Energy, the EU Commission and several other public bodies.

If somebody has a story they want told and are willing to pay to have that story told it is only human nature that someone will gladly help them out when the right incentives are in place. This is a superb explanation of what happens.
Universities and departments have set policies to attract climate science funding. Climate science centers don’t spontaneously spring into existence – they were created, in increasingly rapid numbers, to partake in the funding bonanza that is AGW. This by itself is not political – currently, universities are scrambling to set up “clean energy” and “sustainable technology” centers. Before it was bio-tech and nanotechnology. But because AGW-funding is politically motivated, departments have adroitly set their research goals to match the political goals of their funding sources. Just look at the mission statements of these climate research institutes – they don’t seek to investigate the scientific validity or soundness of AGW-theory, they assume that it is true, and seek to research the implications or consequences of it.

This filters through every level. Having created such a department, they must fill it with faculty that will carry out their mission statement. The department will hire professors who already believe in AGW and conduct research based on that premise. Those professors will hire students that will conduct their research without much fuss about AGW. And honestly, if you know anything about my generation, we will do or say whatever it is we think we’re supposed to do or say. There is no conspiracy, ust a slightly cozy, unthinking myopia. Don’t rock the boat.

Gender wage discrimination starts early

The BBC report the results of the 2009 Halifax Pocket Money Survey. Halifax have been carrying out the survey since 1987 and have found that over that time pocket money has increased by more than four times the rate of inflation. Halifax are most interested in the savings behaviour shown but there are some other interesting findings.

The UK average pocket money for 2009 is £6.24 a week which is an 11p or 1.8% increase on the 2008 figure but is still substantially below the 2005 high of £8.37 a week. The UK's Office of National Statistics combined the Halifax survey with their own data to create the following graph.

Children with family incomes in the highest income decile received the biggest amount of pocket money. Interestingly, the next highest recipients were children whose family incomes were in the lowest income decile. The data do not allow us to determine if pocket money is a substitute for or additional to other expenditure by parents across the income deciles.

The higher than inflation increases in pocket money have not been evenly distributed with those in the 8-11 age group getting an average of £4.80 a week in 2009 which is some 425% above the 1987 figure of £1.13 reported here. Those in the 12-15 age bracket are getting the higher amount of £7.44 a week but this is "only" some 215% higher than the £3.46 their counterparts from 1987 were receiving. The survey also reports big regional variations across the country but one of the more standout findings is that:

Across the country, boys received an average of £6.88, compared with girls' £5.58.

This difference of £1.30 per week equates to a pocket money differential of about 23%. Gender wage discrimination, it seems, starts early!

Ireland may be neutral but her money is not

Bloomberg recently ran a report looking at the returns earned by Irish Life, Ireland's biggest fund manager. The report begins:
Dec. 3 (Bloomberg) -- Irish Life Investment Managers, Ireland’s biggest fund company, is defending its top-ranked returns by investing in makers of military equipment.

Brendan Moran, who oversees 15 billion euros ($22.6 billion) as head of global equities at the Dublin-based company, bought Lockheed Martin Corp. and BAE Systems Plc because he predicts defense budgets will stay high.

“Their share prices haven’t gone up; the earnings haven’t come down,” Moran, 42, said in an interview at Bloomberg’s Dublin bureau. “As a consequence, they are more attractive to us on valuation.”

The U.S. government in October authorized a further $130 billion for military operations in Iraq and Afghanistan, bringing to more $1 trillion the amount spent since the Sept. 11 terrorist attacks. President Barack Obama said Dec. 1 he will send an extra 30,000 troops to Afghanistan next year.

The 12 members of the Standard & Poor’s 500 Aerospace & Defense Index trade at an average ratio of 13 times their earnings compared with an average 22 for companies in the Standard & Poor’s 500 Index.
Public opinion in Ireland is in favour of our neutrality stance. After the first Lisbon Treaty research conducted on behalf of the Department of Foreign Affairs indicated that uncertainty about Irish neutrality was a significant issue in the rejection of the Treaty. The Irish Defence Forces will not be sending any equipment or personnel for military operations in Iraq and Afghanistan. But we will be investing plenty of our money into the effort.

You can listen to a short interview with Brendan Moran here who airs his concerns about the impact changes in global defense budgets may have for his Irish investors. Neutral how are you!

Who's smart?

New Geography has just released a survey of the world's smartest cities and lists "the 'smartest' cities not only by looking at infrastructure and livability, but also economic fundamentals". Singapore comes out on top with Amsterdam the only European entry, though the list is a little Americentric with seven cities (four US, one Mexico, one Brazil and one Canada) on the list.
  1. Singapore: The 21st-century successor to 15th-century Venice, this once-impoverished island nation now boasts an income level comparable to the wealthiest Western countries, with a per-capita GDP ahead of most of Europe and Latin America. Singapore Airport is Asia's fifth-largest, and the city's port ranks as the largest container entrepot in the world. Over 6,000 multinational corporations, including 3,600 regional headquarters, are located there, and it was recently ranked No. 1 for ease of doing business.

This country has an aspirational plan based around Building Ireland's Smart Economy. Maybe Ireland (population 4.45 million) should be having a look at what Singapore (population 4.75 million) is doing to smarten up. Reading Singapore's Success: Engineering Economic Growth would be a good start. This reveals that Singapore implements many economically efficient (though politically unpopular) policies so that Singapore:

  • has unilateral free trade
  • admits unusually large numbers of immigrants
  • supplies most medical care on a fee-for-service basis
  • means-tests most government assistance
  • imposes peak load pricing on roads, and
  • fights recessions by cutting employers' taxes

Brian Caplan offers three possible explanations of the paradoxes of Singaporean political economy.

Serious floods lead to broken windows

In an article in yesterday's Irish Times, the ESRI's Prof Richard Tol suggests that the clean-up operation may boost the economy. A short extract gives the main details.
Prof Richard Tol of the Economic and Social Research Institute (ESRI) has said that while the flooding has caused widespread damage, there may be an unexpected fillip to the economy once the clean-up operation begins. “Floods are bad but flood restoration can actually provide a stimulus to the economy,” said Dr Tol.

Dr Tol pointed out that he was not downplaying the impact the floods had on people who lost their homes and businesses, some of whom were not insured. However, he said that one of the unusual consequences of the restoration work, once it begins, is that it will provide an economic stimulus, generating local work and business in construction, engineering and in retail sales.

“What the water has done is it has destroyed many things. But once insurance is paid, there will be a lot of money coming into the country. Most of the funds will come not from Irish insurance companies but will be called in from international reinsurers. So it will be mostly coming from abroad, which is a stimulus.”

He said that consumption would increase in affected areas as restoration work began, providing a measurable boost. “As such there is a silver lining to the flood,” he added.

A silver lining! An estimated €250 million euro worth of property has been destroyed and Tol finds a "silver lining". Quick, get the ESB to open up more dams! The path out of the recession has been found. Surely they'd be able to cause at least double the damage again in no time at all and we'd have twice as much of this "silver lining". And don't send the army in to help people. Have them get out the heavy artillery (they do have guns, don't they?) and blow up buildings and stuff on high grounds that escape the floods. Pretty soon we'll have enough "silver lining" for everybody.

Richard Tol, what are you at? Yes the floods will lead to expenditure on repairs but that money will come from reduced expenditure elsewhere. Open your other eye! Have you every heard of The Lesson which Hazlitt brought to us from the work of Federic Bastiat. You must have!

Here is Hazlitt's piece on the simplest application of The Lesson as proposed by Bastiat. The Broken Window is short enough to reproduce here in it's entireity. Read it. Think of the €250 million that will be spent on flood repairs. Read it again.
Let us begin with the simplest illustration possible: let us, emulating Bastiat, choose a broken pane of glass.

A young hoodlum, say, heaves a brick through the window of a baker’s shop. The shopkeeper runs out furious, but the boy is gone. A crowd gathers, and begins to stare with quiet satisfaction at the gaping hole in the window and the shattered glass over the bread and pies. After a while the crowd feels the need for philosophic reflection. And several of its members are almost certain to remind each other or the baker that, after all, the misfortune has its bright side. It will make business for some glazier. As they begin to think of this they elaborate upon it. How much does a new plate glass window cost? Two hundred and fifty dollars? That will be quite a sum. After all, if windows were never broken, what would happen to the glass business? Then, of course, the thing is endless. The glazier will have $250 more to spend with other merchants, and these in turn will have $250 more to spend with still other merchants, and so ad infinitum. The smashed window will go on providing money and employment in ever-widening circles. The logical conclusion from all this would be, if the crowd drew it, that the little hoodlum who threw the brick, far from being a public menace, was a public benefactor.

Now let us take another look. The crowd is at least right in its first conclusion. This little act of vandalism will in the first instance mean more business for some glazier. The glazier will be no more unhappy to learn of the incident than an undertaker to learn of a death. But the shopkeeper will be out $250 that he was planning to spend for a new suit. Because he has had to replace a window, he will have to go without the suit (or some equivalent need or luxury). Instead of having a window and $250 he now has merely a window. Or, as he was planning to buy the suit that very afternoon, instead of having both a window and a suit he must be content with the window and no suit. If we think of him as a part of the community, the community has lost a new suit that might otherwise have come into being, and is just that much poorer.

The glazier’s gain of business, in short, is merely the tailor’s loss of business. No new “employment” has been added. The people in the crowd were thinking only of two parties to the transaction, the baker and the glazier. They had forgotten the potential third party involved, the tailor. They forgot him precisely because he will not now enter the scene. They will see the new window in the next day or two. They will never see the extra suit, precisely because it will never be made. They see only what is immediately visible to the eye.

Aren't all these international insurance companies nice to be giving us this "stimulus" money to pay for the flood repairs and they'd never want it back. Would they?

UPDATE: Prof. Tol took his ideas from the paper of record and put them over the airwaves with George Hook on Newstalk's The Last Word. You can listen to the short interview by going here.

All Bar None

The CSO produce data on the value and volume of trade in the Bar sector. The graph below reproduces the seasonally adjusted values of the sales index in the sector from Jan 2005 to Sep 2009. Ouch!

The gap between the two value and volume series emerges because of price inflation. It is clear that most of this happened between 2006 and 2008 with the gap between the two relative constant for at least the last 12 months. Here are price indices for four catergories of licensed trade products.

Although we are experiencing some deflation in the economy this is not the case in the bar trade (yet! ) . With prices falling the VFI and LVA tried to become the drinkers friend by announcing a prize freeze from Dec 1 2008! This was ruled illegal by the Competition Authority but may still have force has an informal agreement.

The price graph above very defined "steps" suggesting coordinated price increases across the entire sector rather than gradual or dispersed price increases. If we lookly at the monthly percentage price increases based on the above data.

We see there are five months where all prices rose by between 1 and 1.75% in that month alone. For most other months the change in price is essentially zero. The Vintners may argue that they are simply passing on price increases from their suppliers. However for the graph to tie in with that story the wholeprices of brewers, distillers, wine distributors, cider producers and soft drink manufacturers would all have to rise by the same amount in the same month.

If we look at four key categories in the retail grocery sector we don't see anything like the same level of co-movement of prices.

Drink Driving Limits and Cost/Benefit Analysis

The recent debate surrounding Minister for Transport Noel Dempsey's proposals to reduce the legal alcohol limit for drivers from 80mg to 50mg of alcohol per 100ml of blood provides an interesting insight on the economist's tool of Cost/Benefit Analysis.

On one side we have the Minister arguing that the benefits of the measure will be the lives saved as a result of the new law. On the other side we have TDs such as Mattie McGrath (FF, South Tipperary) suggesting that the costs of the new measure will be increased isolation of people, especially older people, in rural Ireland.

As a decision-making tool the decision rule in a Cost/Benefit Analysis is relatively simple. Once all the relevant costs and benefits have been monetised an action should be taken if the value of the benefits exceeds the value of the costs. That is, the action or policy results in a net benefit or gain to society.

The current drink driving debate highlights one the major difficulties in appropriately undertaking a cost/benefit analysis: monetising the benefits. The proposals put a reduction in deaths and injuries from road accidents versus increased isolation of the rural community as the opposing costs and benefits. These are factors that have no direct monetary value and so must be valued indirectly if a true cost/benefit comparison is to be made.

Each side will also seek to increase the values supporting their view and reduce the values that should be placed on the factors on the opposite side. For example if we consider the public mutterings of those against the measures we can see that they have argued that the benefits should be lower and the costs of higher.

They have suggested that the true figure for the reduction in road deaths is lower than what is the Minister has presented. Mattie McGrath has also argued that a drink or two has a relaxing effect on people and can make some people better drivers, a loss which increases the costs of the measure. On an interview on Newstalk he said, "some people, if drink is such a sedative, it can make people who are jumpy on the road, or nervous, be more relaxed".

Looking at those backing the measure European Transport Safety Council director Antonio Avenoso has said that:
"...saving lives was more important than any perceived threat to rural social life.

We should also not forget that rural communities have also been shattered and
devastated by lives lost, by people who have brain damage and by people who have
long-standing injuries because of traffic accidents due to drink driving."
The Road Safety Authority has gone a step further and half done one half a Cost/Benefit Analysis. They have argued that the benefits of the new regulations can be valued at €70 million per year. This is as a result of a reduction in accidents leading to 10 fewer deaths, 100 fewer injuries and less damage caused. Cliona Murphy of Alcohol Action Ireland has argued that the costs of imposing the new rules should be zero.
"With regard to all alcohol-related issues, this is probably as clear-cut as it gets. I'm at a loss to understand why a person's right to have a pint and drive overrides my right to drive on roads free from alcohol."
Working out who is right or otherwise is a complex task and not the issue here. The aim here is to merely highlight the difficulties that arise when trying to undertake a cost/benefit analysis when monetising the factors cannot be done directly.

To finish we will take one claim and see if it stands up to scrutiny - the claim by the RSA that this measure will save 10 lives per year.

The key report on this issue is based on research done by Dr Declan Bedford et al for the HSE. The report which covers the three year period 2003 to 20055 is available here and a recent slideshow presentation of the report is available here.

According to the report 18 drivers were killed in the three year period who had a blood alcohol content of between 50mg and 80mg per 100 ml of blood. This is legal under current law but would be illegal if the proposed measures are introduced. This gives an average of six deaths per year. Four below the figure of ten as promoted by the RSA. Can we get there?

Thus far we have only included drivers. Other fatalities on the road occur among pedestrians/cyclists and passengers. Using figures in the report it is possible to suggest that about 1.5 pedestrian/cyclist deaths per year could be avoided if the new rules were implemented. This is found by multiplying the following numbers. Proportion of accidents in which driver alcohol is an issue (31%), proportion of these accidents in which blood alcohol is between 50mg and 80mg per 100ml (8%) and average number of pedestrian/cyclists deaths per year where pedestrian/cyclist alcohol is not an issue (57). A similar analysis for passenger deaths suggest that there would be two less passenger deaths per year if the blood alcohol limit was reduced to 50mg.

This puts the total number of deaths reduced at six plus one and a half plus two giving a total of 9.5. We're not too far off the quoted figure ten less deaths per annum. Can we find another 0.5?

In 35% of driver deaths no blood alcohol readings were taken or were not available to the researchers. It is likely that in some proportion of these cases alcohol was an issue but the data is not available to reveal this. In many cases tests may not be undertaken because there are clear reasons to suggest that such a test is unnecessary. Still, there are bound to have been a (small?) number of cases where data is not available but driver blood alcohol of between 50mg to 80mg per 100ml is present. We can assume that these cases will result in 0.5 road deaths per year.

We now have support for the RSA claim of a reduction of 10 road deaths per year that forms part of the €70 million per annum benefit if the new measures are introduced.

Is there an issue here?

YES! The RSA analysis is based on the assumption that the reduction in the limits will result in the elimination of ALL deaths that were a result of driver blood alcohol of between 50mg and 80mg. All of them!

If this is to true then it must be that there are no deaths above the current 80 mg limit. Of course not. 80% of killed drivers with alcohol had blood alcohol above 80mg. Of those with alcohol the average reading was 88.9mg per 100 ml.

How many deaths will be avoided if the blood alcohol limit is reduced to 50mg? In fact, the first question should be "will any deaths be avoided?". The answer to this question is probably "yes" but the number is undoubtedly less than ten, maybe even substantially so.

Do I know the answer? No. Just be careful what you read when it comes to pronouncements on a cost/benefit analysis!

Split or Steal?

Jasper Carrot teaches Game Theory.

The TV game show Goldenballs concludes with two contestants facing off in a situation that is a variation of The Prisoners' Dilemma. The main workings of the early part of the game are unimportant, what is of interest here is the final round.

Each contestant chooses a ball, either Split, which means they try and split the jackpot with the other contestant or Steal which means they try and steal the entire jackpot for themselves. There are three outcomes as follows:

  • Both players choose Split: The winnings are split equally between them.
  • One player chooses Steal, the other Split: The player who played 'steal' gets all the money.
  • Both players choose Steal: No-one gets any money.

The conclusion of one such episode is shown in the following clip.

The problem is the same as The Prisoner’s Dilemma except it is not quite as pure. This is a one shot game, but the players are in the same room, in fact, they’re looking right at each other, their friends and family are watching and they are given the opportunity to convince the other person of their intention to either Split or Steal. There is more at stake than some money, their reputation amongst all people for one. On top of all of this they have been playing a game for the past half hour and have had the chance to betray each other already.

The similarities with the Prisoner's Dilemma are:

  1. It is a game of cooperation (share) or defection (steal).
  2. Decisions are made simultaneously.
  3. It is a one shot game

The major differences are:

  1. This is a zero-sum game.
  2. The players can communicate.
  3. Steal (defect) is only a weakly dominant strategy

Here is some analysis of the decisions involved:

The worst outcome in this game is for the players to both choose ‘steal’ as that would mean no one wins the jackpot. All other scenarios mean the full jackpot is given to at least one of the players. At initial inspection it may appear that the jackpot will be given out ¾ times and no jackpot a ¼ of the time. But the interesting thing with this game is that assuming all players behave rationally the outcome will actually always be that no one wins the jackpot (i.e. two steals).

If you put yourself in the position as a player, you can see how this works. There are two possible options that your opponent can choose (‘steal’ or ‘split’).

Take scenario 1 where your opponent chooses ‘split’. Here if you choose ‘split’ you will get half the jackpot, if you choose ‘steal’ you will get the entire jackpot. So obviously any rational person will choose ‘steal’ as this will maximise your winnings.

Take scenario 2 where your opponent chooses ‘steal’, in this scenario it is irrelevant whether you choose ‘steal’ or ‘split’ because either way you will get nothing. So given the scenario 2 decision is irrelevant (as ‘steal’ and ‘split’ both result in 0) your decision should be based purely on scenario 1 where it has already been illustrated that any rational person will choose ‘steal’.

So the optimum strategy for any player is ‘steal’! Of course the problem with this is that your opponent has the same options as you and therefore will pick ‘steal’ which means the game ends in two ‘steals’. So going back to the game show assuming that all participants are rational human beings the first 55 minutes of the show are irrelevant because whatever the jackpot ends up being the result of the game will always end up with no one wining anything.

So what actually happens when people are faced with this choice on the show. The show is currently half way through its sixth series and in the five and a half series to date 253 episodes have been broadcast. Data on the 40 episodes in the first series are available here. This gives us a sample of 80 people who were presented with the Goldenballs Dilemma. The average jackpot competed for in the 40 episodes was £12,975.76.

Even though we have shown that 'steal' is the weakly dominant strategy of the 80 contestants, 42 of them chose 'split', or just over 52%, with the other 38 contestants obviously choosing 'steal'.

There were 12 episodes in which both contestants chose 'split' and the jackpot was divided. The average split jackpot was £9,245.49. That leaves 18 people choosing 'split' who had 'steal' played against them and ended up with nothing. The average stolen jackpot was £17,807.14. In the remaining ten episodes both contestants choose 'steal' and the jackpot was lost. The average lost jackpot was £8,742.25.

So the outcomes were:

Both players choose Split:- 12 episodes (30%) Average jackpot = £9,256.49
One player chooses Steal, the other Split:- 18 episodes (45%) Average jackpot = £17,807.14
Both players choose Steal:- 10 episodes (25%) Average jackpot = £8,742.45

Putting an Economics Degree to Work

Robert Mugabe, President (Dictator?) of Zimbabwe does not suffer from a shortage of education. In the 1950s, 60s and 70s he earned no less than seven degrees. These are not honorary degrees of which he has many, though some have since been revoked.

Mugabe has three Bachelors degrees, in Economics, Education, and History and Literature. While imprisoned for 11 years from 1963 to 1974 he completed four degrees by correspondence which were awarded by the University of London. He gained a Masters degrees in Economics, a Bachelors degree in Administration as well as two Law degrees.

Thus with two Economics degrees including a Masters one would expect that Mugabe would have a grasp of basic economic concepts. One example should be enough to question the value of these degrees.

Question: What is the solution to rampant inflation?
Mugabe: Print more money and introduce price controls.

Here is a stunning image that brilliantly illustrates that Mugabe has little understanding of the role of property rights and the effect of The Tragedy of the Commons on economic outcomes. This image gives an aerial view of farmland in Zimbabwe.

The Centre for Global Development provides a handy interactive tool using this and other images. They also provide the following analysis which gives a nice pointer on causality.

Land reform begun in Zimbabwe in 2000 was supposed to redistribute land from predominantly white-owned commercial farms to much poorer black farmers who toiled on communal lands. Proponents argued that the redistribution was necessary because commercial farms occupied the most fertile lands, leaving only dry, dusty land for communal use. This rationale reflects confusion about cause and effect regarding land ownership and land quality. In the "Before" photo below, the dry communal lands on the left are sharply delineated from the green private farms dotted with lakes and ponds on the right--so sharply that soil quality and rainfall are unlikely to explain the difference. Now click the arrow to see what happened after land reform. The dams and irrigation systems on the private farms collapsed, making them look more like communal lands, to the detriment of all.

This is not the only aerial image that shows the power on institutions in determining economic outcomes. Check out this night time image of the Korean peninsula.

Finally there is the suggestion that it is not the fault of Robert Mugabe and other failed economists that they have such a poor understanding of the subject. The Economic Naturalist , Robert Frank in a 2005 New York Times column wrote the following:

Virtually all economists consider opportunity cost a central concept. Yet a recent study by Paul J. Ferraro and Laura O. Taylor of Georgia State University suggests that most professional economists may not really understand it. At the 2005 annual meetings of the American Economic Association, the researchers asked almost 200 professional economists to answer this question:

"You won a free ticket to see an Eric Clapton concert (which has no resale value). Bob Dylan is performing on the same night and is your next-best alternative activity. Tickets to see Dylan cost $40. On any given day, you would be willing to pay up to $50 to see Dylan. Assume there are no other costs of seeing either performer. Based on this information, what is the opportunity cost of seeing Eric Clapton? (a) $0, (b) $10, (c) $40, or (d) $50."

The opportunity cost of seeing Clapton is the total value of everything you must sacrifice to attend his concert - namely, the value to you of attending the Dylan concert. That value is $10 - the difference between the $50 that seeing his concert would be worth to you and the $40 you would have to pay for a ticket. So the unambiguously correct answer to the question is $10. Yet only 21.6 percent of the professional economists surveyed chose that answer, a smaller percentage than if they had chosen randomly.

When they posed their original question to a large group of college students, the researchers found that exposure to introductory economics instruction was strikingly counterproductive. Among those who had taken a course in economics, only 7.4 percent answered correctly, compared with 17.2 percent of those who had never taken one.
Maybe Mugabe would be better able to deal with Zimbabwe's hyper-inflation if he'd never taken an Economics degree!

Hot dog, anyone?

Here is a very interesting article about a failed hot-dog vendor in New York. He missed rent payments on his license to sell hot-dogs from a cart on the steps outside the Metropolitan Museum of Art. What's so interesting about this? Well his annual rent was $642,696!!!

Hot dog heartache has come to the Metropolitan Museum of Art, where the Parks Department on Friday evicted a weiner vendor who couldn't pay his $53,558 monthly rent.

The frankfurter failure is Pasang Sherpa, 51, of Long Island City, who agreed late last year to pay almost $643,000 annually for the right to sell food and drinks from carts on either side of the iconic steps. He fell $310,000 behind on rent and the city has seized $170,000 in Sherpa's assets.

A worker at one of the carts who was hanging up his tongs Friday night said it brought in just $1,000 to $1,500 a day - not enough to cover the sky-high rent. Sherpa was the highest bidder last year when the Parks Department auctioned the right to sell hot dogs there. It is the most lucrative spot in the city, in front of one of New York's top tourist attractions with no nearby stores or restaurants.

The same paper reports that Sherpa got a job from one of his fellow cart operators, Dan Rossi, and notes their problems with unlicensed vendors.

"He's gonna work for me now," said Rossi. "Nobody's gonna touch him now without talking to me."

"The guy was crying. They pushed him out," Rossi said.

"Yeah, I'll work for him now," Sherpa said yesterday. "It's better than nothing."

"Last night I couldn't sleep," he said. "I've got kids who have to go to college. I don't know what I'm going to do."

Sherpa and Rossi say the city needs to do a better job keeping so called "black market" hot dog vendors away from the Met. "As soon as they pulled Sherpa's cart out yesterday, all these guys just pulled in. The city has to enforce the law," said Rossi.

These unlicensed dealers offer dogs and drinks for less money than the legit businessmen, whose prices are set by the Parks Department. "I sell water for $2 and the others sell it for $1," he said. "If I charged $10 a hot dog maybe I could compete."

Back in January The New York Post reported the agreement that Sherpa would be selling hot dogs at $2 dollars each. That's almost 320,000 unit sales just to cover the rent cost. To put it into perspective consider the comparison to the number of minutes in a year - 525,600. To cover the rent Sherpa needs to sell "one hot dog every 1.6 minutes — and not just during lunch or other normal meal times. Rather, it is assuming Mr. Sherpa (or someone else working for him, presumably for pay) is manning the cart 24 hours a day.

In the same article The Post also reports that altough Sherpa had won the auction to the rights to both the South and North sides of the entrance steps he had paid more than €80,000 for the Northside rights even though there is a little more than 30 yards between them!! The combined rent from the auction for the previous year before rookie Sherpa entered the fray was $415,000.

Hot Dog Cart News (who?) are obviously a cheerleader to the industry and suggest that this may not have been such a crazy deal:

How many hot dogs, chips, and sodas do you need to sell just to break even? Let’s do the math:

Keep in mind this is a premium tourist destination and there is no where else to eat. I’m guessing that a dog, chips and soda would sell for $8. If so, Sherpa needs to serve 80,338 meals to break even. That’s less than 2% of the 5 million folks who walk right by his carts on the way in or out of the Met each year. Granted he has other overhead to cover, but nothing even close to those rent payments. If he sells to just 10% of the tourists he will gross…

Four million dollars a year. I’m getting dizzy.

This analysis is full of holes. What about the capital, labour and materials costs that would be incurred in order to sell the 80,338 meals to cover the rent? The rent is only an element of the fixed costs. The carts, staff and hot dogs do not come free and form part of the variable costs. It is these that determine the break even level. So how did our hero get into trouble? Hot Dog Cart News have the answer:

But here’s a lesson. Before you sign anything, make sure all your ducks are in a row. Only one of Sherpa’s carts passed the health department inspection, and his coveted north entrance will be blocked by construction for months. Again, holy #$&* ! Wouldn’t you have done a little more due diligence before jumping into the big leagues? So now he doesn’t want to pay. Big surprise.

This little case study provides material and examples for a plethora of economic concepts:

  • economic rent, super-normal profits and rent seeking
  • consumer surplus and producer surplus
  • defining, allocating and the value of property rights
  • market structure and barriers to entry
  • fixed and variable costs
  • the short run and long run shutdown decisions
  • ad rem(per unit) versus lump-sum (fixed) charges
  • risk and uncertainty
  • effects of regulation and the value of licenses
  • allocative (in)efficiency of a planned economy
  • competition ($1 water) versus monopoly ($2 water)

and probably most evidently of all

  • auctions and the winner's curse

Tim Harford, in The Undercover Economist, analyses a similar example when it looks at coffee shops, their location and the price of a cappuccino in the first section of the opening chapter which is called "Who Pays for Your Coffee?". You can read the first few pages from this chapter here.

When I Grow Up

The Irish Examiner recently ran a piece in its Weekend supplement (not available online) that featured the results of a survey carried out by a British bank on its 16-21 year old customers. They were asked what jobs would they most like to land when they got older. The results?

1. Musician/Band Member (25%)
2. Working in the Media (24%)
3. Celebrity or Socialite (14%)
4. Fashion Designer (13%)
5. Teacher/Lecturer (13%)

Others to make the list were; nurse (8%), vet (5%), politics (1%) and charity work (1%). Even if only these careers are included we are already over 100%! I have not been able to find the primary source of the data so the techniques used cannot be verified. Maybe respondents were asked to select a number of careers from a list. Anyway, regardless of the methods used Teacher/Lecturer made the top five. In the piece the Examiner asked a person from each of the top five "dream jobs" to describe a typical working day. The chosen five were:

Musician - Paul Walsh
Socialite - Lisa Murphy
TV Presenter - Grainne Seoige
Designer - Ciaran Sweeney
Lecturer - Carol Laffan

Carol is a College Lecturer in Economics in the University of Limerick and here is a run through of her typical day.

7.30am: Alarm goes off. Hug the bed, realising it's cold outside. Hit the shower in an attempt to wake up. I'm not a morning person. Have breakfast with my fiance, a computer engineer.
8.10am: The drive to work takes about 25 minutes. Need to be in the car park before 9am otherwise all the spaces will be gone.
9am: A grab a cup of tea when I get in and bring it to my desk. I reply to my emails and prepare for my lecture.
9.30am: I have an hour and half of office hours for students to call to me. I have these twice a week.
11am: I give a 50-minute lecture, one of four a week. Currently my International Economics students are studying the effects on the economy of multinational companies setting up in Ireland or pulling out of Ireland. It's quite topical at the moment, especially here in Limerick. My Health Economics students are looking at the economics behind health insurance.
12am: Go for a coffee break with my colleagues. Shop talk is strictly prohibited.
12.30pm: Meet one of my final year project students one-to-one to go through the week they've done on their thesis. I have six students to supervise at the moment.
1.30pm: Go for lunch with my colleagues. It's a really good way to bond as a unit.
2.30pm: Prepare my lecture notes for the coming days and put these along with extra readings on my website for the students to download.
4pm: Answer my emails. I phone some of the BBS co-op students who are doing their work placement overseas. All students on work experience either get a visit or a phone call from a member of the school to check in on their progress so this year I'm calling the international placements.
5pm: Work on my PhD thesis. I try to clear one full day a week, but the college year really flies by. Therefore, I get a lot of my research and writing done over the holidays.
7pm: I get home and we cook dinner. We sit down and talk about our respective days. I usually make a few phone calls to organise a few bits for my upcoming wedding in July.
8pm: Prepare for tomorrow's lectures, meetings etc. Watch some television in an attempt to unwind.
9.30pm: Sort out my clothes and bits for the morning. This gives me five more glorious minutes in bed in the morning. Then I'll read until I fall asleep around midnight.

The Oberserver got the "scoop" on (or provided the inspiration for) The Examiner as about a month beforehand they ran a very similar piece on the survey. This time the lecturer chosen was Dr Leo Mellor a lecturer in English at at Murray Edwards College, Cambridge. You can read about his typical day here. His day and schedule follow the same lines as Carol's, but he only gives two lectures a week.

For those with a continuing unhealthy interest in Economics Lecturers in the UL, The Limerick Leader, recently ran a piece on Dr Stephen Kinsella. Among the many questions he was asked was:

Away from work, what are your pastimes and hobbies? I have no pastimes whatsoever. Any spare time I do have, I spend with my kids, Allan, two and a half and Cillian, ten months. Which is why I have zero hobbies. But at the moment, betwee research, teaching and things like Bizcamp, a lot of my life is taken up with work.
