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.

President Obama has proposed a major reform of the US banking system. This follows on from the proposed levy to be imposed on banks’ assets announced a few days ago (see “We want our money back and we’re going to get it”).
There are two elements to the new proposals. The first is to limit the size of banks’ market share. Currently, banks’ deposits are not permitted to exceed 10% of total retail deposits in the USA. This 10% limit would be extended to cover wholesale deposits and other liabilities. The idea is to reduce concentration and increase competition. At present the largest four banks hold over half the total assets of banks in the USA.
The second element involves separating casino banking from retail banking. This would be achieved by barring retail banks from owning or investing in private equity or hedge funds or from engaging in ‘proprietary trading operations’. As the second BBC article below states:
Proprietary trading involves a firm making bets on financial markets with its own money, rather just than carrying out a trade for a client in which only the client’s money is at risk.
This comes close to restoring the Glass-Steagall Act, which was repealed in 1999. The Act, which was passed in 1933 in the wake of the 1929 Wall Street cash and the subsequent Great Depression, separated commercial banking and investment banking. It was designed to prevent customers’ deposits being exposed to the riskier activities of investment banking.
What have been the reactions to President Obama’s announcement? Are these reactions justified? Will the proposals prevent another banking crisis and credit crunch? The following articles explore these questions.

- Would putting a limit on the market share of banks prevent them from achieving full economies of scale?
- Why did banking shares fall after President Obama’s announcement? Was this a ‘good sign’ or a ‘bad sign’?
- What is meant by the ‘broker-dealer’ function of banks? Explain each of the specific types of broker-dealer function.

“As snow sweeps the country, the UK has coped in the way it usually does – with surprise, confusion and chaos.” Not only have the transport authorities in many areas struggled to cope, but individuals too have been caught out. Many have rushed to stock up on things such as blankets, fires, de-icing equipment and warming foods.
But why does Britain cope worse than many other countries? Should more resources be diverted into keeping roads, airports and rail lines open? And how have individuals responded? How much have they stocked up on a range of cold-weather items and why? The linked article looks at these issues?

Questions
- Does it make economic sense for the UK to invest relatively little in snowy-weather infrastructure?
- How should a local authority decide whether or not to (a) buy an additional gritting lorry; (b) increase its stock piles of grit? How would risk attitudes affect the decision?
- Why might a lower proportion of people get to work in the recent snowy weather than in equivalent weather 20 years ago?
- How might you define a ‘thermal elasticity of demand’ for a product, where the determinant of demand is the temperature?
- What factors determine the thermal elasticity of demand for a product? How is the short-term elasticity likely to be different from the longer-term elasticity and why?
- What would you need to include in measuring the full social costs to the economy of the cold spell?
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.

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.”
