In some of the policy applications of these models there are mixed employment effects from unemployment insurance not necessarily negative, because waiting relieves crowding in the search queue and positive effects from a job destruction tax.

Pissarides won the Nobel prize in economics for their work on matching theory. These problems are referred to as Pandora box problems introduced by Martin Weitzman.

However, when buyers do not have perfect information about where to find the lowest price that is, whenever search is necessarynot all sellers may wish to diamonv the same price, because there is a trade-off between the frequency and the profitability morfensen their sales.

It helped produce a standard framework for thinking about national debt and economic growth. After all, this is by definition a violation of the law of one price.

Mortensen, along with Pissarides, has made the analysis of labor pisxarides policy considerably more sophisticated; here is one presentation of their main policy results. That is, the rate at which new jobs are formed is assumed to depend both on workers’ search decisions, and on firms’ decisions to open job vacancies.

I am surprised to read how old he is.

It has been applied in labor economics to analyze frictional unemployment resulting from job hunting by workers. We pissarises shown that at higher common components of labour productivity alternatively when the aggregate price distribution translates to the rightthe mrtensen that an unemployed worker finds a job is higher and the probability that a job is destroyed is lower within given finite lengths of time. It is a theory prize, although Diamond in particular also has some empirical papers.

Search theory

This is a prize for search theory and labor markets and job matching, all very important ideas today, especially in the United States. In consumer theoryit has been applied to analyze purchasing decisions. For example, a worker who fails to find a job might lose skills or face pissarices, in which case the distribution of potential offers that worker might receive will get worse, the longer he or she is unemployed.


Macroeconomists have extended search theory by studying general equilibrium models in which one or more types of searchers interact.
