Abstract

We characterize efficient allocations and business cycle fluctuations in a labor-selection model. Due to forward-looking hiring costs and labor supply decisions, efficiency entails both static and intertemporal dimensions. We develop welfare-relevant measures of marginal rates of transformation and efficiency along each margin and show how they nest their counterparts in the frictionless RBC model. In a calibrated version of the model, efficient fluctuations feature highly volatile unemployment and job-finding rates, in line with empirical evidence. We show analytically in a simplified version of the model that volatility arises from selection effects, not associated general equilibrium effects. We also develop sufficient conditions on wages that support efficient allocations in a decentralized economy. These conditions are independent of the wage-determination process, unlike the well-known Hosios condition for matching models, which assumes Nash-bargained wages. Also unlike the Hosios condition, there is no simple restriction on Nash bargaining that guarantees that Nash wages can support efficient allocations. Cyclical fluctuations in the Nash-bargaining economy display even larger amplification of productivity shocks into labor market outcomes than in the efficient economy, without extreme assumptions about bargaining shares, inflexibility of wages, or the size of surpluses that govern labor demand. The results establish normative and positive foundations for DSGE labor selection models.
