Contributions to economics

As Palda wrote in 2013

In his 1974 and 1986 articles Sherwin Rosen invited what would happen if you were limited in how you could proceed about through characteristics space. Rosen covered out that sometimes when buying a product with several underlying characteristics you could not just go out and span characteristics space by buying a ingredient 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 a person engaged or qualified in a profession. 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 give and demand of complicated tied sales situations through a monetary payment he called an “equalizing difference”. This construct led to numerous unexpected insights on the effects of government policy. For example, the minimum wage might not decrease employment, as economists ordinarily believed, but it might induce employers to give less on-the-job training to employees. In addition to implications for policy, Rosen's analysis of choice in characteristics space with tied sales listed the conditions under which the parameters of demand and supply function parameters for the underlying characteristics of goods could be deduced from so-called hedonic regressions.
