Two Americans and a British-Cypriot economist won the 2010 Nobel economics prize Monday for developing a theory that helps explain why many people can remain unemployed despite a large number of job vacancies.
Federal Reserve board nominee Peter Diamond was honored along with Dale Mortensen and Christopher Pissarides with the 10 million Swedish kronor ($1.5 million) prize for their analysis of the obstacles that prevent buyers and sellers from efficiently pairing up in markets.
Peter Diamond has analyzed the foundations of search markets. Dale Mortensen and Christopher Pissarides have expanded the theory and have applied it to the labor market. The Laureates' models help us understand the ways in which unemployment, job vacancies, and wages are affected by regulation and economic policy. This may refer to benefit levels in unemployment insurance or rules in regard to hiring and firing. One conclusion is that more generous unemployment benefits give rise to higher unemployment and longer search times.
Search theory has been applied to many other areas in addition to the labor market. This includes, in particular, the housing market. The number of homes for sale varies over time, as does the time it takes for a house to find a buyer and the parties to agree on the price. Search theory has also been used to study questions related to monetary theory, public economics, financial economics, regional economics, and family economics.
