Why Tobin Taxes Wouldn’t Have Prevented The Financial Crisis

24 November, 2009

The Economist discusses the populist rhetoric from Gordon Brown on the topic of the Tobin Tax, a fee levied by government on any financial transaction. US Treasury Secretary Tim Geithner admits that any such policy would be useless unless adopted world-wide, because trading would simply migrate to unregulated jurisdictions.

Public support for such measures is worrying though, as the Tobin Tax is ineffective in preventing risk-taking in financial markets or harmful asset price bubbles. It would be extremely effective at making markets inefficient though..

Rolling Back the Rules of the Road

1 August, 2009

Traffic ConeThe Christian Science Monitor has a fascinating piece on how traffic laws cause accidents, by diminishing the attention that drivers pay to the roads and reducing their reliance on their own best judgement. Could their complete absence improve matters?

There is clearly a simple trade-off here. Drivers can choose to concentrate on the road, thus making them better equipped to react to unexpected occurrences and more aware of their surroundings. They could alternatively just trust the lights and the signs.

Passing the Buck

17 July, 2009

Credit CardThe New York Times reports as the largest pension fund in the country, the California Public Employees Retirement System (CalPERS) sues credit rating agencies for forcing them to make risky investment decisions and ignore the potential for a market down-turn. Oh, no wait. That’s not an accurate description of the events that transpired at all.

27 June, 2009

Silver DollarIn 1890, the Silver Purchase Act threatened to cause inflation – to the benefit of farmers and miners, at the expense of business interests and banks. As the Great Depression of the 1930s raged, real wages of labourers continued to climb.

The most recent financial crisis was characterised by defaulting sub-prime borrowers, who were lent more money than they could afford. It is no coincidence that in each case, depression was invited or prolonged by politics championing a reallocation of society’s resources.

The World Without Limited Liability

12 June, 2009

DiceIt was suggested recently here that limited liability had proven inappropriate for the banking system. Gambles which are rational from the perspective of individual banks can threaten the economic system, when business confidence is affected by the aggregated effect of all these risks.

Banks are all interdependent. There were other problems that contributed, but no doubt the contribution of stockholders and traders who were indifferent between leaving a company destitute, or insolvent and indebted for millions. Is it possible though to imagine a world without limited liability?

How to Reform Risk Management

10 June, 2009

MoneyIn recent times, traders have been accused of taking excessive risks. Unfortunately, the structure of remuneration in financial markets tends to exacerbate animal spirits by creating incentives for risk-taking.

Traders benefit dramatically in prestige and bonuses when successful. Meanwhile, they don’t suffer when they do badly as society foots the bill. This agency problem in finance is described as the ‘Trader Option’.

Making Bondholders Pay?

29 May, 2009

The Irish Economy debates the merits of proposals from Fine Gael to allow the banks to default on bondholders. There have been naïve claims from the government that such a move would increase the cost of lending for the state.

Meanwhile, such talk pushes up the cost of lending for Irish banks. It effectively makes the guarantee of bank debt by the government null and void in the minds of investors, and chills them to the prospect of lending.
