Abstract
A standard endogenous separation model developed by Mortensen and Pissarides (1994) has a drawback in replicating the negative correlation between unemployment and vacancy rates. To address this issue, I extended the model by incorporating wage rigidity and modifying the assumption about idiosyncratic match-specific productivity. Results indicate that introducing wage rigidity can produce the Beveridge curve, while the degree of negative correlation is slightly lower than that presented in the data. Modifying the model to randomly draw match-specific productivity for new matches also increases the degree of negative correlation between unemployment and vacancy rates. These results suggest that an endogenous separation model can explain the observed variation by adding frictions.
期刊介绍:
Economic Modelling fills a major gap in the economics literature, providing a single source of both theoretical and applied papers on economic modelling. The journal prime objective is to provide an international review of the state-of-the-art in economic modelling. Economic Modelling publishes the complete versions of many large-scale models of industrially advanced economies which have been developed for policy analysis. Examples are the Bank of England Model and the US Federal Reserve Board Model which had hitherto been unpublished. As individual models are revised and updated, the journal publishes subsequent papers dealing with these revisions, so keeping its readers as up to date as possible.
