Employment Protection in Dual Labor Markets: Any Amplification of Macroeconomic Shocks?

Abstract This paper studies the effects of labor market duality in terms of employment legislation protection (EPL) on labor market volatilities. Modeling contractual heterogeneity through a gap in EPL of temporary and permanent workers (weakly protected temporary/highly protected permanent contracts), I simulate both supply and demand shocks in a New Keynesian model with unemployment. I find that unemployment fluctuations follow an inverted U-shape over the magnitude of the EPL gap: small EPL gaps amplify, while large EPL gaps dampen the reaction of unemployment. In a subsequent empirical analysis, I find that the model’s predictions are consistent with panel data for a large set of OECD countries. Uncovering the non-linear course of unemployment volatility helps reconcile previous divergent research results.
