James Tobin
James Tobin (March 5, 1918 – March 11, 2002) was an American economist who served on the Council of Economic Advisers and the Board of Governors of the Federal Reserve System, and taught at Harvard and Yale Universities. He developed the ideas of Keynesian economics, and advocated government intervention to stabilize output and avoid recessions. His academic work included pioneering contributions to the study of investment, monetary and fiscal policy and financial markets. He also proposed an econometric model for censored endogenous variables, the well-known "Tobit model". Tobin received the Nobel Memorial Prize in Economic Sciences in 1981.
Financial transaction tax
Although James Tobin had said his own Tobin tax idea was unfeasible in practice, a study on its feasibility commissioned by the German government 2002 concluded that the tax was feasible even at a limited scale within the European time zone without significant tax evasion. Joseph Stiglitz, former Senior Vice President and Chief Economist of the World Bank, said, on 5 October 2009, that modern technology meant that was no longer the case. Stiglitz said, the tax is "much more feasible today" than a few decades ago, when Tobin recanted. However, on 7 November 2009, at the G20 finance ministers summit in Scotland, the head of the International Monetary Fund, Dominique Strauss-Khan, said, "transactions are very difficult to measure and so it's very easy to avoid a transaction tax." Nevertheless, in early December 2009, economist Stephany Griffith-Jones agreed that the "greater centralisation and automisation of the exchanges' and banks' clearing and settlements systems ... makes avoidance of payment more difficult and less desirable."
