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.
Tobin tax
In those same "years" that Buiter spoke of, the Tobin tax was also "adopted" or supported in varying degrees by the people who were not, as he put it, "enemies of trade liberalisation." Among them were several supporters from 1990 to 1999, including Larry Summers and several from 2000 to 2004, including lukewarm support from George Soros.
