In several of the posts in recent months we’ve considered the possible use of a Tobin tax as a means of reducing speculation in financial markets and possibly raising substantial amounts in tax revenue. See, for example: Tobin or not Tobin: the tax proposal that keeps reappearing and A Tobin tax – to be or not to be?. Although James Tobin’s original proposals referred to a tax on foreign exchange transactions, recent proposals have been to impose such a tax on a whole range of financial transactions.
Added impetus has been given to the move to adopt Tobin taxes by the publication of a video from an organisation known as the Robin Hood Tax Campaign. To quote the site “The Robin Hood Tax is a tiny tax on bankers that would raise billions to tackle poverty and climate change, at home and abroad. By taking an average of 0.05% from speculative banking transactions, hundreds of billions of pounds would be raised every year. That’s easily enough to stop cuts in crucial public services in the UK, and to help fight global poverty and climate change.”
So would this version of a Tobin tax work? The following videos and articles examine the proposal.

The health of an economy is generally measured in terms of the growth rate in GDP. A healthy economy is portrayed as one that is growing. Declining GDP, by contrast, is seen as a sign of economic malaise; not surprisingly, people don’t want rising unemployment and falling consumption. The recession of 2008/9 has generally been seen as bad news.
But is GDP a good indicator of human well-being? The problem is that GDP measures the production of goods and services for exchange. True, such goods and services are a vital ingredient in determining human well-being. But they are not the only one. Our lives are not just about consumption. What is more, many of our objectives may go beyond human well-being. For example, the state of the environment – the flora and fauna and the planet itself.
Then there is the question of the capital required to produce goods and maintain a healthy and sustainable environment. Capital production is included in GDP and the depreciation of capital is deducted from GDP to arrive at a net measure. But again, things are left out of these calculations. We include manufactured capital, such as factories and machinery, but ignore natural capital, such as rain forests, coral reefs and sustainable ecosystems generally. But the state of the natural environment has a crucial impact on the well-being, not only of the current generation, but of future generations too.
In the video podcast below, Professor Sir Partha Dasgupta, from the Faculty of Economics at the University of Cambridge and also from the University of Manchester, argues that the well-being of future generations requires an increase in the stock of capital per head, and that, in measuring this capital stock, we must take into account natural capital. In the paper to which the podcast refers, he argues “that a country’s comprehensive wealth per capita can decline even while gross domestic product (GDP) per capita increases and the UN Human Development Index records an improvement.”

Questions
- Why might a rise in GDP result in a decline in human well-being?
- In what sense is nature ‘over exploited’?
- What is meant by ‘comprehensive wealth’ and why might comprehensive wealth per capita decline even though the stocks of both manufactured capital and human capital are increasing?
- What is meant by ‘shadow prices’ in the context of natural capital?
- How might economists go about measuring the shadow prices of capital?
- What factors should determine the rate of discount chosen for projects that impact on the future state of the environment?
At the end of two weeks of often acrimonious wrangling between representatives from 193 countries, an agreement – of sorts – was reached at the climate change summit in Copenhagen. What was this agreement? It was an ‘accord’ brokered by the USA, China, India, Brazil and South Africa.
This Copenhagen Accord contains three elements. The first is a recognition of the need to prevent global temperatures rising by more than 2 degrees Celsius above pre-industrial levels. The second is a commitment by developed countries to give $30bn of aid between 2010 and 2012 to developing countries for investment in green technology and to mitigate the effects of climate change. In addition, a goal was set of providing $100bn a year by 2020. The third is for rich countries to give pledges on emissions reductions and for developing countries to give pledges on reducing emissions increases. Developed countries’ pledges will be scrutinised by the UN Framework Convention on Climate Change, while developing countries will merely be required to submit reports on their progress in meeting their pledges.
But this is only an accord. It has no legal status and was merely ‘recognised’ by the countries at the conference. What is more, the target of limiting temperature rises to 2C does not contain a date by which temperature rises should peak. Also, as countries are not required to submit targets for emissions until February 2010, it is not clear how these targets will be kept low enough to meet the temperature target and there is no identification of penalites that would apply to countries not meeting their pledges.
Not surprisingly, reactions around the world have been mixed. The following podcasts and articles look at these reactions and at the economic mechanisms that will be required to meet the 2C limit

In these news blogs, we’ve considered a Tobin tax on a number of occasions: see A Tobin tax – to be or not to be? and Tobin’s nice little earner. On 10 December 2009, the Treasury published a discussion document, Risk, reward and responsibility: the financial sector and society. This, amongst other things, considers the case for a financial transactions tax – a form of Tobin tax. As Box 4.A on page 35 states:
“James Tobin’s original proposal for a transaction tax was to tax foreign exchange transactions. The purpose of the tax was to tackle excessive exchange rate fluctuation and speculation on currency flows, as Tobin felt that short-term movements in capital flows could severely limit the ability of governments and central banks to follow appropriate domestic policies for their economies.
However, the recent crisis has shown that there is considerable risk inherent in other financial markets. In some of these markets trading volumes have also grown enormously compared to the value of underlying assets. As set out above, instability may result from these markets due to the complex nature of counterparty networks and a lack of transparency, and the transmission of financial shocks through the system.
Recent attention has therefore focused on a broader tax on financial transactions – potentially, this would include trading in a wide range of instruments, currently traded both on and off-exchange.”
The goverment in the UK has recently taken one step in increasing taxes on the financial sector. In its 2009 pre-Budget report, delivered on 9 December (see Cutting the deficit and tackling the recession. Incompatible goals?), a new tax on bank bonuses was imposed. The rate is 50% on bonuses over £25,000. Since then a similar tax has been imposed in France and Germany’s Chancellor, Angela Merkel, said that she found it a ‘charming idea’, although probably not practical under German law. She did support, however, the use of a Tobin tax on financial transactions, similar to the one being considered in the UK. Such a tax, to be effective, would ideally have to be imposed worldwide, but at least by a large number of countries.
So is the case for a Tobin tax gathering momentum? The following video podcast considers the tax’s aims, effectiveness and practicality – as do the articles.

- Explain how a Tobin tax could be used to reduce destabilising speculation without preventing markets moving to longer-term equilibria.
- How might the use of a Tobin tax on financial transactions help to curb some of the ‘excessive rewards’ made from financial dealing?
- Examine the advantages and disadvantages of using a Tobin tax on financial transactions. How might the disadvantages be reduced?

Should economists have foreseen the credit crunch? A few were warning of an overheated world economy with excessive credit and risk taking. Most economists prior to 2007/8, however, were predicting a continuation of steady economic growth. Inflation targeting, fiscal rules and increasingly flexible markets were the ingredients of this continuing prosperity. And then the crash happened!
So why did so few people see the downturn coming? Were the models used by economists fundamentally flawed, or was it simply a question of poor assumptions or poor data? Do we need a new way of modelling the economy, or is it simply a question of updating theories from the past? Should, for example, models become much more Keynesian? Should we abandon the new classical approach of assuming that markets are essentially good at pricing in risk and that herd behaviour will not be seriously destabilising?
The following podcast looks at these issues. “Aditya Chakrabortty’s joined in the studio by the Guardian’s economics editor Larry Elliott, as well as Roger Bootle, the managing director of Capital Economics, and political economist and John Maynard Keynes biographer Robert Skidelsky. Also in the podcast, we hear from Nobel prize-winning economist, Elinor Ostrom, Freakonomics author Steven Levitt, and UN advisor and developmental economist Daniel Gay.”
