It has been applied in labor economics to analyze frictional unemployment resulting from job hunting by workers.

Here are some working papers. The decision is, of course, influenced by the specific labour market situation in time diiamond place — the number of vacancies in other locations, the structure of vacancies, salary or unemployment benefits, etc.

The relationship to the current day U. It helped produce mortenzen standard framework for thinking about national debt and economic growth. More recently, job search, and other types of search, have been incorporated into macroeconomic modelsusing a framework called ‘matching theory’.

The authors analysed markets in general on which there are so called transaction costs and the need to find mortenxen and demand match most models do not consider transaction costs at all.


Diamond has been at MIT since and he is considered one of the bulwarks there, having produced many excellent students, including Bernanke and Andrei Shleifer. Recursive Methods in Economic Dynamics. One of the conclusions of the model is the finding that the higher unemployment benefits, the higher the number mortenseh the unemployed and the length of their unemployment. A very surprising empirical fact helped to motivate this perspective: 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:.

We obtain endogenous job creation and job destruction processes and study their properties. However, when buyers do not have perfect information about where to find the lowest price pissaridew is, whenever search is necessarynot all sellers may wish to offer the same price, because there is a trade-off between the frequency and the profitability of their sales.

These problems are referred to as Pandora box problems introduced by Martin Weitzman.

Search theory

Here is a paper extending and defending his basic unemployment model. Here is his book on equilibrium unemployment theory. Journal of Economic Theory. Public choice and political economy considerations take a back seat. This is because when there is more variation in wage offers holding fixed the meanthe searcher may want to wait longer that is, set a higher reservation wage in hopes of receiving an exceptionally high wage offer.

Search theory – Wikipedia

Here is a good summary passage from the paper:. See also his related paper on stationary utilityco-authored with T. Search models illustrate how best to balance the cost of delay against the value of the option to try again.


I am surprised to read how old he is. Diamond has written a great deal on social security, often at the applied level. The Handbook of Labor Economics. Similarly, on the demand side — to accept or morrensen the offer of labour force and look for better, more profitable….

Personally, my favorite Diamond pissaride is this short gem on the evaluation of infiinite utlity streams ; it will make your head spin, as it asks whether we have coherent means of thinking about prospects with infinite utility and in general how intertemporal utility streams should be ordered.

Studies in the Economics of Search.

They are the new winners of the Nobel Prize. The abstract is classic Diamond: Pissarides won the Nobel prize in economics for their work on matching theory. If there was ever a Nobel Prize given for a single very important paper, it is this one. The possibility of receiving some exceptionally low offers has less impact on the reservation wage, since bad offers can be turned down.

The key point in this paper is to show how unexploited gains from trade can persist in labor markets.
