High levels of government debt and the adverse effect this has on the economy has been a key influencing factor in the fiscal consolidation efforts across the world. A key factor providing evidence in support of the connection between high government debts and low economic growth was a paper by two Harvard economists. However, the data used in their research has been called into question.
As we saw in a previous post, It could be you, Carmen Reinhart and Kenneth Rogoff presented a paper back in January 2010. Their research suggested that when a country’s debt increases above 90% of GDP, economic growth will slow considerably. (Click here for a PowerPoint of the above chart.) As you might expect, given the timing of this research, policymakers were intrigued. For those governments in favour of cuts in government spending and increases in taxation to bring the government debt down, this research was dynamite. It seemed to provide the evidence needed to confirm that if left to grow, government debt will have a significantly adverse effect on growth. Here was evidence in favour of austerity.
But, did a simple error create misleading information? A student at the University of Massachusetts Amherst was trying to replicate the results found by Reinhart and Rogoff, but was unable to do so. Thomas Herndon contacted the Harvard professors and they sent him the spreadsheets they had used in their calculations. Looking through it, an error in calculating the average GDP was spotted. However, the student and his supervisors also engaged in further research and came across other inconsistencies. This led to a draft working paper being published in April. The paper did find the same correlation between high debt levels and low growth, but the outstanding results found by Reinhart and Rogoff disappeared. Responding to the error, the Harvard professors said:
We are grateful to Herndon et al. for the careful attention to our original Growth in a Time of Debt AER paper and for pointing out an important correction to Figure 2 of that paper. It is sobering that such an error slipped into one of our papers despite our best efforts to be consistently careful. We will redouble our efforts to avoid such errors in the future. We do not, however, believe this regrettable slip affects in any significant way the central message of the paper or that in our subsequent work.
So, how might this correction and the implications affect government policy? Are we likely to see a reversal in austerity measures? Only time will tell.

The US dollar has been used as the international currency for the majority of international trade. Around 85% of foreign-exchange transactions are trades between US dollars and other currencies. As the first article below, from the Wall St Journal, states:
When a South Korean wine wholesaler wants to import Chilean cabernet, the Korean importer buys US dollars, not pesos, with which to pay the Chilean exporter. Indeed, the dollar is virtually the exclusive vehicle for foreign-exchange transactions between Chile and Korea, despite the fact that less than 20% of the merchandise trade of both countries is with the US.
… The dollar is the currency of denomination of half of all international debt securities. More than 60% of the foreign reserves of central banks and governments are in dollars.
But things are gradually changing as countries increasingly by-pass the dollar. Several countries have reached agreements with China to allow companies to exchange their currencies directly in so-called ‘currency swap‘ arrangements (see also). These include Japan, Australia, the UK, France/the eurozone, Argentina, Brazil, South Korea, Chile and Russia. But while these currency swap arrangements apply to current account transactions, there are still considerable controls of currency movements on China’s capital and financial accounts.
So what will be the implications for the USA and for China? What will be the impact on currency and bonds markets? The following articles explore the issues.

Interest rates have, for some years, been the main tool of monetary policy and of steering the macroeconomy. Across the world interest rates were lowered, in many cases to record lows, as a means of stimulating economic growth. Interest rates in the UK have been at 0.5% since March 2009 and on 2nd May 2013, the ECB matched this low rate, having cut its main interest rate from 0.75%. (Click here for a PowerPoint of the chart.)
Low interest rates reduce the cost of borrowing for both firms and consumers and this in turn encourages investment and can boost consumer expenditure. After all, when you borrow money, you do it to spend! Lower interest rates will also reduce the return on savings, again encouraging spending and for those on variable rate mortgages, mortgage payments will fall, increasing disposable income. However, these above effects are dependent on the banks passing the ECB’s main interest rate on its customers and this is by no means guaranteed.
Following the cut in interest rates, the euro exchange rate fell almost 2 cents against the dollar.
Interest rates in the eurozone have been at 0.75%, but a 0.25 point cut was widely expected, with the ongoing debt crisis in the Eurozone continuing to adversely affect growth and confidence. A lack of trust between banks has also contributed to a lack of lending, especially to small and medium sized enterprises. The ECB has injected money into financial institutions with the aim of stimulating lending, but in many cases, banks have simply placed this extra money back with the ECB, rather than lending it to other banks or customers. The fear is that those they lend to will be unable to repay the money. In response to this, there have been suggestions of interest rates becoming negative – that is, if banks want to hold their money with the ECB they will be charged to do it. Again, the idea is to encourage banks to lend their money instead.
Small and medium sized businesses have been described as the engine of growth, but it is these businesses who have been the least able to obtain finance. Without it, they have been unable to grow and this has held back the economic recovery. Indeed, GDP in the Eurozone has now fallen for five consecutive quarters, thus prompting the latest interest rate cut. A key question, however, will be how effective this quarter of a percent cut will be. If banks were unwilling to lend and firms unwilling to invest at 0.75%, will they be more inclined at 0.5%? The change is small and many suggest that it is not enough to make much of a difference. David Brown of New View Economics said:
The ECB rate cut is no surprise as it was well flagged by Draghi at last month’s meeting. Is it enough? No. The marginal effect of the cut is very limited, but at least it should have some symbolic rallying effect on economic confidence.
This was supported by Howard Archer at HIS Global Insight, who added:
Admittedly, it is unlikely that the trimming of interest rates from 0.75% to 0.5% will have a major growth impact, especially given fragmented credit markets, but any potential help to the eurozone economy in its current state is worthwhile.
Inflation in the eurozone is only at 1.2%, which is significantly below the ceiling of 2%, so this did give the ECB scope for the rate to be cut. (Click here for a PowerPoint of the chart.) After all, when interest rates fall, the idea is to boost aggregate demand, but with this, inflation can emerge. Mr Draghi said ‘we will monitor very closely all incoming information, and assess any impact on the outlook for price stability’. The primary objective of the ECB is the control of inflation and so had inflation been somewhat higher, we may have seen a different decision by the ECB. However, even then, 5 consecutive quarters of negative growth is hard to ignore.
So, if these lower interest rates have little effect on stimulating an economic recovery, what about a movement away from austerity? Many have been calling for stimulus in the economy, arguing that the continuing austerity measures are stifling growth. The European Council President urged governments to promote growth and job creation. Referring to this, he said:
Taking these measures is more urgent than anything … After three years of firefights, patience with austerity is wearing understandably thin.
However, Mr. Draghi urged for policymakers to stick with austerity and continue to focus on bringing debt levels down, while finding other ways to stimulate growth, including structural reform. The impact of this latest rate cut will certainly take time to filter through the economy and will very much depend on whether the 0.5% interest rate is passed on to customers, especially small businesses. Confidence and trust within the financial sector is therefore key and it might be that until this emerges, the eurozone itself is unlikely to emerge from its recession.

Imagine if none of the clubs in the English Premier League (EPL) or English Football League (EFL) had junior or youth teams. Instead envisage a situation where all of the talented young footballers in the country go to college or university to develop their skills. Then once a year there is a big televised event where each of the clubs in the EPL and EFL take it in turns to choose which young college/university players they would like to recruit.
Strange as it sounds to football fans in Europe this is exactly what happens in American Football in the USA. It is called the NFL draft and this year’s event took place over three days between 25th and 27th April at Radio City Music Hall in New York. There was greater interest in Britain than usual in this year’s event because of the involvement of 24 year old Menelik Watson who was born and raised in Manchester. Although originally a basketball player, coaches spotted his potential to play American football in the NFL and two years ago he obtained a place at Florida State University.
The NFL draft has seven rounds. Each of the 32 teams has the right to choose one player in each round. An important design issue for any draft system is how to determine the running order in which the teams make their choices. Obviously all 32 teams would like to get the first chance at recruiting the most talented of all the college players. The NFL’s solution to this allocation problem is an interesting one. The team with the worst playing record from the previous season gets the first choice in each round. In the 2012-13 season this happened to be the Kansas City Chiefs who played 16 games and only won 2 of them. The second choice in each round goes to the team with the 2nd worst playing record from the previous season and so on. The final choice in each round goes to the previous year’s Super Bowl champions who in the 2012–13 were the Baltimore Ravens. Another interesting characteristic of the system is the ability of teams to trade draft choices. For example in 2013 the Oakland Raiders traded their choice in the first round (which was the 3rd choice overall) with the Miami Dolphins for their choices in both the first and second round (12th and 42nd choice overall).
What is the rationale for having a draft system? It was first introduced in February 1936 and many commentators have argued that it has been a key factor which has helped to maintain competitive balance in sport. The man behind the idea, Bert Bell of the Philadelphia Eagles, argued that without this type of system the sport would be dominated by the 4 richest teams. He stated that:
Every year, the rich get richer and the poor get poorer. Four teams control the championship. Because they are successful, they keep attracting the best college players in the open market, which makes them more successful.
Some evidence for the success of the scheme is that in the last 15 years the Super Bowl has been won by 10 different teams. However in 1934, just before the scheme was proposed, there was another major issue for team owners. The Brooklyn Dodgers and the Philadelphia Eagles had become involved in a bidding war for a very talented young player called Stan Kostka. Brooklyn won the battle but had to pay him a salary of $5,000 – the same amount that was paid to the star player in the league. Some people have argued that the real purpose of the draft scheme was to limit the pay of young players by effectively reducing any competitive bidding for their services. Once drafted, a player is expected to join the team who selected him. There may be some protracted negotiations over his final salary and bonuses but the only option open to him if an agreement breaks down is to re-enter the draft the following year. This effectively gives the teams monopsony power which may enable them to restrict players pay to below that of their marginal revenue product. For example although Andrew Luck, the first choice draft pick in 2012, reportedly earns just over $20million from his 4 year contract with the Indianapolis Colts some commentators have argued that his true market value is over $100 million.
The good news for Menelik Watson was that he was finally drafted by the Oakland Raiders and was the 42nd overall player chosen in the draft process. This is the highest choice ever made by a team in the NFL for a player born and brought up in Britain. The final outcome for the league as a whole can be seen on the NFL website.

In The global economy we note the mixed picture contained within the latest British growth numbers. With the first estimate of growth for Q1 of 2013 pointing to an increase in real GDP of 0.3 per cent, the UK economy appears to have missed the ignominy of a triple dip recession. However, the overall economy remains fragile with different sectors of the economy performing quite differently.
A patchy picture is perhaps the fairest assessment. This helps to explain the quite different perceptions amongst economists, business people, journalists and the wider public about the current state of the economy. Here we consider in a little more detail the growth numbers for the UK from the latest preliminary GDP estimates. (Click here for a PowerPoint of the chart).
The British economy is thought to have grown by 0.3 per cent in the first quarter of 2013. This follows a contraction of 0.3 per cent in the final quarter of 2012. Compared with the first quarter of 2012, the output of the British economy was 0.6 per cent higher. However, as Chart 2 helps to show, the British economy has some way to go before it returns to the levels seen prior to the financial crisis. Real GDP peaked in the first quarter of 2008 when GDP at 2009 prices was estimated at £372.7 billion. In the first quarter of 2013, GDP at constant 2009 prices is estimated at £362.9 billion. This means that the economy is still 2.6 per cent smaller than its 2008-peak. Click here for a PowerPoint of the chart.
The patchy nature of British growth is illustrated nicely by the contrasting rates of growth across the different industrial sectors in the first quarter of the year. While service sector output rose by 0.6 per cent, output across the production industries rose by only 0.2 per cent and agricultural output declined by 3.7 per cent. Within the production industries, mining and quarrying output rose by 3.2 per cent, but manufacturing output shrunk by 0.3 per cent and construction output shrunk by 2.5 per cent.
Chart 3 compares the output of agriculture, the production industries and the service sector between the first quarter of 2008 and the first quarter of 2013. (Click here for a PowerPoint of the Chart). It shows the dramatically different experience of the service sector compared with agriculture and the production industries. While output in the service sector is now 0.8 per cent higher, output across agriculture and the production industries is almost 13.5 per cent lower. Within the production industries, output in mining and quarrying is 38 per cent lower, in the construction sector 19 per cent lower and 10 per cent lower in manufacturing. It is perhaps not surprising then that we get such different messages about the state of the economy. The devil really is in the detail.
