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.

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!

Questions
- What were the particular errors made by Reinhart and Rogoff?
- How has their paper been used as a basis for the design of macroeconomic policy?
- What are the limitations of using even accurate time-series data as the basis for policy measures?
- How might the work of Herndon change the direction of future macroeconomic policy?
- In his guest post in Business Insider (see link above), Herndon wrote: ‘The implication for policy is that, under particular circumstances, public debt can play a key role in overcoming a recession.’ What might this role be?
- Why might we have to be cautious in drawing policy conclusions from Herndon’s work?
On 5 and 6 April, there was a conference on conscious capitalism in San Francisco. In January, a new book, Conscious Capitalism: Liberating the Heroic Spirit of Business, by John Mackey and Rajendra Sisodia, was published. Many in the business world are enthusiastic about this seemingly new approach to business, which focuses on broader social, environmental and ethical goals, rather than simple profit maximisation.
As the Washington Times review linked to below states:
“Conscious Capitalism” promotes a business culture that embodies “trust, accountability, caring, transparency, integrity, loyalty and egalitarianism.” The management ideal of “Conscious Capitalism” contains four key elements of “decentralization, empowerment, innovation and collaboration.” Above all, this exemplary form of business practice relies on careful attention to four tenets: higher purpose and core values, stakeholder integration, conscious leadership and conscious culture and management.
So how realistic is this vision of caring capitalism? There may be a few inspiring businesspeople, truly committed to improving the interests of the various stakeholders of their business and society more generally, but could it become a model for business in general? And if so, does this require education, monitoring and regulation? Or can a libertarian approach to business generate an environment where conscious and caring capitalists flourish and succeed better than those with a more narrow focus on profit?
The following videos and articles discuss conscious capitalism and the arguments of those, such as John Mackey, founder and co-CEO of Whole Food Market, who advocate it.

- How might firms that are not pursuing conscious capitalism be persuaded to become more conscious and more caring?
- How does conscious capitalism differ from corporate social responsibility?
- What would you understand by “conscious consumers”? How might their behaviour differ from other consumers?
- Why might firms engaging in conscious capitalism become more profitable than firms that have a simple aim of profit maximisation?

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.

The UK economy faces a growing problem of energy supplies as energy demand continues to rise and as old power stations come to the end of their lives. In fact some 10% of the UK’s electricity generation capacity will be shut down this month.
Energy prices have risen substantially over the past few years and are set to rise further. Partly this is the result of rising global gas prices.
In 2012, the response to soaring gas prices was to cut gas’s share of generation from 39.9% per cent to 27.5%. Coal’s share of generation increased from 29.5% to 39.3%, its highest share since 1996 (see The Department of Energy and Climate Change’s Energy trends section 5: electricity). But with old coal-fired power stations closing down and with the need to produce a greater proportion of energy from renewables, this trend cannot continue.
But new renewable sources, such as wind and solar, take a time to construct. New nuclear takes much longer (see the News Item, Going nuclear). And electricity from these low-carbon sources, after taking construction costs into account, is much more expensive to produce than electricity from coal-fired power stations.
So how will the change in balance between demand and supply affect prices and the security of supply in the coming years. Will we all have to get used to paying much more for electricity? Do we increasingly run the risk of the lights going out? The following video explores these issues.

- What factors have led to a rise in electricity prices over the past few years? Distinguish between demand-side and supply-side factors and illustrate your arguments with a diagram.
- Are there likely to be power cuts in the coming years as a result of demand exceeding supply?
- What determines the price elasticity of demand for electricity?
- What measures can governments adopt to influence the demand for electricity? Will these affect the position and/or slope of the demand curve?
