Job Searchers, Job Matches and the Elasticity of Matching

This paper stresses the importance of a specification of the matching function in which the measure of job matches corresponds to the measure of job searchers. In many empirical studies on the matching function this requirement has not been fulfilled because it is difficult to find information about employed job searchers and job searchers from outside the labour market. In this paper, we specify and estimate matching functions where the flow corresponds to the correct stock. We use several approximations for the stock of non-unemployed job searchers. We find that the estimation results are sensitive to the approximation we use. Our main conclusion is that it is important to account for the behaviour of non-unemployed job searchers since otherwise the estimated parameters of the matching function may be seriously biased.
