One of the newer concepts that can be applied to the labour market is the so- called Diamond-Mortensen-Pissarides model. The authors analysed markets in.

In microeconomicssearch theory studies buyers or sellers who cannot instantly find a trading partner, and must therefore search for a partner prior to transacting.
Here is a recent paper on growth through product innovation you can google to an ungated version, though the pdf has no link. In models of matching in the labor market, two types of search interact. More precisely, search theory studies an individual’s optimal strategy when choosing from a series of potential opportunities of random quality, under the assumption that delaying choice is costly. This imparts a cyclical asymmetry in the job destruction rate and in the dynamic behaviour of unemployment.
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. The major continental economies failed to match UK performance because of institutional rigidities, despite low inflation expectations. Search from one or more unknown distributions is called a multi-armed bandit problem.
Here is his paper on macro and social security reform. Here is his short introduction on behavioral economics.
That is, firms may be indifferent between posting a high price thus selling infrequently, only to those consumers with the highest reservation prices and a low price at which they will sell more often, because it will fall below the reservation price of more consumers. The worker’s optimal strategy is simply to reject any wage offer lower than the reservation wage, and accept any wage offer higher than the reservation wage. A key point is to analyze not just the first-order effect of the labor market policy but also its incidence, and thus its second-order effects on search and job matching.
We have shown that at higher common components of labour productivity alternatively when the aggregate price distribution translates to the rightthe probability 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. They are the new winners of the Nobel Prize. Of the three winners, I think of Pissarides as the least Keynesian of the trio.

Here is his survey on social security reform proposals. December Learn how and when to remove this template message. But the increase in job destruction immediately after the cyclical omrtensen has no counterpart in the behaviour of the job destruction rate when price increases, or in the behaviour of the job creation rate.

Here is a good summary passage from the paper: Likewise, if the worker is risk aversethe reservation wage will decline over time if the worker gradually runs out of money while searching. There is also an asymmetry between job creation and job destruction, due to option value, and thus discrete cut-offs for job creation and job destruction, and that leads to a central result of the paper:.
They also belong among the pioneers of the mortemsen theory. Here is a good summary passage from the paper:. We show that an aggregate shock induces negative correlation between job creation and job destruction whereas a dispersion shock induces positive correlation.
Here is his very good Econometrica piece on wage stickinessabstract:.
Here pissagides his very good Econometrica piece on wage stickinessabstract: The reservation wage may change over time if some of the conditions assumed by McCall are not met. The key question is why workers with similar characteristics often are paid differently and the answers lie in job search frictions. This is a prize for search theory and labor markets and job matching, all very important ideas today, especially in the United States. Another conclusion of the discussed model is as follows: We obtain endogenous job creation and job destruction processes and study their properties.
If the worker refuses, the cost is the lost income form the rejected job.
