This paper measures the job-finding, separation, and job-to-job transition rates in the United States from 1948 to 2004. The job-finding and job-to-job transition rates are strongly procyclical and the separation rate is nearly acyclical, especially since 1985. The author develops a simple model in which unemployed workers search for jobs and employed workers search for better jobs. The model predicts that an increase in either the job-finding rate or the separation rate raises the job-to-job transition rate, which is qualitatively and quantitatively consistent with the available evidence. In contrast, if the job-finding rate were acyclical and the separation rate countercyclical, as is the conventional wisdom, the model predicts that the job-to-job transition rate would be counterfactually countercyclical.

This paper argues that the textbook search and matching model cannot generate the observed business-cycle-frequency fluctuations in unemployment and job vacancies in response to shocks of a plausible magnitude. In the United States, the standard deviation of the vacancy-unemployment ratio is almost 20 times as large as the standard deviation of average labor productivity, while the search model predicts that the two variables should have nearly the same volatility. A shock that changes average labor productivity primarily alters the present value of wages, generating only a small movement along a downward-sloping Beveridge curve (unemployment-vacancy locus). A shock to the separation rate generates a counterfactually positive correlation between unemployment and vacancies. In both cases, the model exhibits virtually no propagation.

An increase in the share of youth in the working age population of one state or region relative to the rest of the United States causes a sharp reduction in that state's relative unemployment rate and a modest increase in its labor force participation rate. This is inconsistent with many theories of the labor market, but can be easily explained by a model of frictional unemployment with on-the-job search. The theory makes strong predictions regarding the behavior of wages which are shown to be consistent with the data. The paper also reconciles its findings with an existing body of apparently contradictory empirical evidence. [ABSTRACT FROM AUTHOR]

This paper constructs a tractable general equilibrium model of search with risk aversion. An increase in risk aversion reduces wages, unemployment, and investment. Unemployment insurance has the opposite effect: insured workers seek high-wage jobs with high unemployment risk. An economy with risk-neutral workers achieves maximal output without any unemployment insurance, but an economy with risk-averse workers requires a positive level of unemployment insurance to maximize output. Therefore, moderate unemployment insurance not only improves risk sharing but also increases output. [ABSTRACT FROM AUTHOR]
