Sherwin Rosen (September 29, 1938 – March 17, 2001) was an Americanlaboreconomist. He had ties with many American universities and academic institutions including theUniversity of Chicago, theUniversity of Rochester,Stanford University and itsHoover Institution. At the time of his death, Rosen was Edwin A. and Betty L. Bergman Distinguished Service Professor in Economics at theUniversity of Chicago and president of theAmerican Economic Association.

Rosen received his B.S. in economics fromPurdue University in 1960, his M.A. and Ph.D. in economics from theUniversity of Chicago in 1962 and 1966 respectively.

He was chair of the Economics department at theUniversity of Chicago and colleague to an impressive range of celebrated economists including friendGary S. Becker. He was elected to theNational Academy of Sciences in 1997.

Rosen died at theBernard Mitchell Hospital on March 17, 2001, at the age of 62.

As Palda wrote in 2013^[1]

In his 1974 and 1986 articles Sherwin Rosen asked what would happen if you were limited in how you could move about through characteristics space. Rosen pointed out that sometimes when buying a product with several underlying characteristics you could not just go out and span characteristics space by buying a bit of another product with the same characteristics but in different proportions. The reason was that sometimes when you buy something, you are selling something at the same time and are able to sell uniquely to one purchaser. Recombining goods to balance characteristics to suit your tastes is not possible. Rosen called such exchanges tied-sales.

Rosen showed that tied sales could lead to the segregation of people by their types. He argued that the worst effects of segregation could be palliated by a market that resolved supply and demand of complicated tied sales situations through a monetary payment he called an "equalizing difference". This work led to many unexpected insights on the effects of government policy. For example, the minimum wage might not decrease employment, as economists commonly believed, but it might induce employers to provide less on-the-job training to employees. In addition to implications for policy, Rosen's analysis of choice in characteristics space with tied sales specified the conditions under which the parameters of demand and supply function parameters for the underlying characteristics of goods could be deduced from so-calledhedonic regressions.
