Lars Peter Hansen, an economist at the University of Chicago, is one of three winners of this year’s Nobel Memorial Prize in Economic Science, along with Eugene F. Fama, a fellow professor at the University of Chicago, and Robert J. Shiller, a professor at Yale.
The Nobel committee cited all of them for contributing to the study of asset prices. But each person’s work is very different.
Professor Fama is known as the father of the “efficient-markets hypothesis,” while Professor Shiller, a frequent contributor to the Economic View column in Sunday Business, is a founder of the field of behavioral finance and is a critic of aspects of Professor Fama’s theory. I interviewed both of them last month, and Professor Shiller has also expressed his views in a column.
Professor Hansen, on the other hand, has received less attention from the news media, and he has stayed clear of the debate over efficient markets and irrational behavior. He has been recognized for creating advanced techniques in econometrics, enabling researchers in many fields of social science to create better mathematical models.
