Most existing DSGE models used for monetary policy analysis and forecasting assume that the labor market always clears at a sticky nominal wage (a la Calvo) through variations along the intensive margin of labor supply (i.e. hours), with no role for the extensive margin (i.e. employment). The latter contrasts with research on the macroeconomics of labor markets that has emphasized the relevance of the extensive margin and employment fluctuations using search and matching theory. Against this background, in this paper we conduct a horse race of a labor market specification with Calvo wages versus a search and matching specification with endogenous separations in an otherwise standard New Keynesian small open economy model, estimated with Chilean data. We conclude that the search and matching specification “wins” by a wide margin as it significantly improves the model’s ability to explain and predict both labor market data and other macroeconomic variables.
