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.

The latest growth data for the UK is somewhat difficult to interpret. It’s positive, but not that positive. The Conservatives say it shows that the economy is moving in the right direction. Labour suggests it is evidence that the Coalition’s policies are not working. With a return to positive growth, the UK has avoided the triple dip recession and here we take a closer look at the economic performance of other key nations.

In the final quarter of 2012, the US economy grew at 0.4%, but in the 3 months to March 2013, economic growth in America picked up to 2.5%. Consumer spending significantly increased, growing at an annualized rate of 3.2%, according to the Commerce Department. This figure helped boost the growth rate of the US economy, as consumer spending accounts for around two thirds of economic activity.

However, the growth figure was lower than expected, in part due to lower government spending. Furthermore, there are suggestions that the positive consumer spending figures are merely a positive blip and spending will fall as the US economy moves through 2013.

If this does prove to be the case in the USA, it will do little to further boost UK economic growth, which was recorded at 0.3% for the first 3 months of 2013. The Chancellor has said that the growth figures are encouraging and are evidence that the government’s policies are working.

Today’s figures are an encouraging sign the economy is healing … Despite a tough economic backdrop, we are making progress. We all know there are no easy answers to problems built up over many years, and I can’t promise the road ahead will always be smooth, but by continuing to confront our problems head on, Britain is recovering and we are building an economy fit for the future.

While the USA and UK have recorded positive growth, expectations of growth throughout Europe remain uncertain. Spain has revised its forecasts downwards for 2013, expecting the economy to shrink by over 1%. Even after 2013, growth is expected to remain very weak, forecast to be 0.5% in 2014 and 0.9% in 2015. To make matters worse, Spain’s unemployment continues to move in the wrong direction, with data for the first 3 months of 2013, recording an unemployment rate of 27.2% – the highest on record.

However, it’s not just Spanish unemployment that is on the rise. Figures for March show that in France, 3.2 million people were out of work, a 1.2 % rise compared to February. In the UK, 2.56 million people were recorded as unemployed, representing just under 8% of the working population. The German economy continues to outperform its European partners, but eurozone growth continues to look weak for the rest of 2013.

Despite much bad news in Europe, growth in other parts of the world remains buoyant. South Korea has recorded economic growth that is at its highest level in 2 years. Economic growth was just under 1%, but construction and investment both increased, perhaps a sign of an economy starting its recovery.

The Chinese economy has seemed relatively unaffected by the economic downturn, yet its economic growth has slowed. Averaging over 10% per annum for the last decade, the growth for January – March 2013 was only 7.7%. This is a decline on the previous 3 months and is lower than expected. If the Chinese economy does begin to slow (relatively speaking), this could present the global economic recovery with an unwelcome obstacle.

Many Western economies are reliant on exports to boost their growth figures and with such high demand in China, this is a key export market for many countries. If the Chinese economy continues to slow, consumer spending may even fall and this could mean a reduction in Chinese imports: that is, a reduction in other countries’ exports to China. However, for China’s competitors, the news is better, as with China’s move from a low to middle-income country, other countries will now see an opportunity to grasp a competitive advantage in the production of cheaper products. David Rees from Capital Economics said:

Trade data show that Chinese imports of commodities, and industrial metals in particular, have been falling in recent months … That is bad news for those emerging markets in Latin America, the Middle East, and Africa that predominately export commodities to China. It is not all bad news … To the extent that China’s structural slowdown reflects its transition from low to middle-income status, opportunities will present themselves for other EMs as China moves up the value chain. We are particularly upbeat on the manufacturing-based economies of South East Asia, along with Mexico, Poland, and Turkey.

News is better in Japan, where growth forecasts have been raised to 2.9% over the same period and the economy is expected to grow by 1.5% throughout both 2013 and 2014. Furthermore, suggestions that inflation may also reach 0.7% have boosted confidence. This might be the end of Japan’s troubles with deflation.

So, we have something of a mixed picture across the world, although the IMF predicts a global rate of growth of 3.5% for 2013, which would be an improvement on 2012 figures. The following articles consider the global situation.

An excellent learning exercise for students of economics is to take a journal article that uses data to model the economy and then try to replicate the authors’ results. You may well be given an assignment like this in future years of your degree.

One such exercise is used on the University of Massachusetts Amherst’s doctoral programme in economics. Thomas Herndon is a student on that degree and chose to examine a well-known and highly influential paper, Growth in a Time of Debt by Carmen Reinhart then of the University of Maryland and Kenneth Rogoff of Harvard University and former chief economist of the IMF. Professors Reinhart and Rogoff used new data on 44 countries spanning about 200 years.

A key finding of their paper, published in 2010 in the American Economic Review Papers and Proceedings, is that once a country’s government debt exceeds 90% of GDP, growth rates fall considerably: the median across countries by about 1% and the mean considerably more.

The paper has been hugely influential. It has been used to justify the austerity programmes being pursued in many countries, including the UK and the eurozone. Cutting the government deficit to GDP ratio, and ultimately the government debt to GDP ratio, has been seen as a way of achieving higher growth over the longer term, and justifies the adverse effect on short-term growth from the dampening of aggregate demand.

Well, this seemed an interesting paper for Thomas Herndon to examine, and he was keen to show just how Reinhart and Rogoff’s data led to their conclusions. But try as he might, he could not replicate their results. His initial reaction was to think he had made an error, but each time he checked he came back with the same conclusion: they must have made errors in their calculations.

His supervisor at Amherst, Professor Michael Ash, after Thomas had checked and checked again, realised that something was wrong. He encouraged Thomas to write to Reinhart and Rogoff to request sight of their dataset. They duly obliged and it was then that Thomas spotted various errors. These are explained in the articles below, but the overall effect was to alter the conclusion. Although high debt may undermine growth to some extent, the effect is much less than Reinhart and Rogoff concluded, and there are several exceptions to this rule.

On 15 April 2013, Thomas, along with his supervisor, Michael Ash and his colleague, Robert Pollin, published a response to the Reinhart and Rogoff paper. In the abstract to their paper, Does High Public Debt Consistently Stifle Economic Growth? A Critique of Reinhart and Rogoff they state that:

… coding errors, selective exclusion of available data, and unconventional weighting of summary statistics lead to serious errors that inaccurately represent the relationship between public debt and GDP growth among 20 advanced economies in the post-war period. They find that when properly calculated, the average real GDP growth rate for countries carrying a public-debt-to-GDP ratio of over 90 percent is actually 2.2 percent, not –0:1 percent as published in Reinhart and Rogoff. That is, contrary to RR, average GDP growth at public debt/GDP ratios over 90 percent is not dramatically different than when debt/GDP ratios are lower.

The authors also show how the relationship between public debt and GDP growth varies significantly by time period and country. Overall, the evidence we review contradicts Reinhart and Rogoff’s claim to have identified an important stylized fact, that public debt loads greater than 90 percent of GDP consistently reduce GDP growth.

So could this be you in the future? Will you take a famous paper and, by re-examining and reworking the data, find that its conclusions are wrong? Could you end up changing the world? Exciting stuff!

Much has been written on Margaret Thatcher following her death at the age of 87 on April 8. But getting a calm assessment of both her time in office and her legacy is not easy. And it’s clear why: she created both stronger loyalty and stronger opposition than any other UK Prime Minister.

As economists, however, we should try to be as dispassionate as possible in assessing the effects of policies. There is always a normative question of the relative desirability of different economic outcomes – and you will have your own views on the relative importance of objectives such as economic growth, greater equality and greater social cohesion – but to determine cause and effect, or at least correlation, requires a careful examination of the evidence. Also, drawing lessons for future policy requires a careful modelling of the economy and the effects of changing economic variables.

The following articles have been selected from the hundreds that have appeared in the press in the past few days. Whilst they cannot be claimed to be totally ‘objective’, taken together they give a good overview of her economic policies and her economic legacy.

You may well have been surprised by the amount of coverage of her death and at the fervour of her supporters and critics. But this bears witness to the huge effect she had on both the political scene and on the UK economy – for good or bad.

VAT was introduced on the 1st of April 1973, as part of the conditions for the UK entering the Common Market. Designed by a French tax expert, Maurice Lauré, it was initially envisaged as a straightforward replacement for purchase tax, which would be applied to most goods and services.

Forty years on, VAT is increasingly complex, with numerous exemptions, many anomalies in its scope, and increasingly expensive challenges to its imposition. How did we get to this point? And is it time for VAT to undergo a mid-life makeover?

All governments have to raise taxes – to redistribute income and to fund public spending. They have a number of mechanisms they can use, but essentially they have to tax incomes (direct taxes), spending (indirect taxes) or a mix of both. The main indirect tax in the UK is VAT, which now raises over £100bn a year, compared with £1.5bn in its first year (see above chart: click here for a PowerPoint version). Initially envisaged as a simple, cross-Europe purchase tax, the current system is complex and at times appears to have been formulated ‘on the hoof’, never a good way to build a tax system.

In the 2012 Budget, the Chancellor decided to apply the standard rate of income tax to hot takeaway pasties; previously they had been zero-rated. However, he had sharply underestimated the ability of the industry to lobby against the tax, working closely with the tabloid press. Perhaps more importantly, he also missed the complex nature of the good; when is a hot pasty just cooling down? And what is hot? The government backtracked and now 20% VAT is only charged on pasties that are deliberately kept hot. You might think that this change of heart avoided introducing an anomaly, but consider how you might feel if you sell takeaway baked potatoes, which are subject to VAT.

Apart from the complexity of the system, VAT is unpopular with some commentators who feel that it falls too heavily on low-income households. Although many foodstuffs are zero-rated and housing is exempt, VAT is charged at 20% on clothing and many necessities such as cleaning materials. Gas and electricity are subject to a reduced rate of 5% and both alcohol and cigarettes have additonal excise duties imposed and yet are disproportionally consumed by the poor. When the standard rate of VAT was temporarily dropped to 15% in 2010, but then permanently raised to 20% in 2011, many felt that this was a shift in the tax burden to the poor.

So complex, irrational and prone to changes following political lobbying or expensive legal cases, VAT does seem to be stumbling into its forties under something of a cloud. However, it remains the case that it raises a large proportion of UK tax revenues at relatively low direct cost and provides the Chancellor with a reasonably effective fiscal policy tool. Even if a government wanted to put in place an alternative, it is likely that the associated political risks would be too high for it to do so. We might hope for some rationalisation of the current system, but there is little doubt that we will be raising a glass to VAT’s 50th birthday in 2023.
