This paper documents state dependence in labour market fluctuations. Using a Threshold Vector Autoregression model (TVAR), we establish that the unemployment rate, the job separation rate, and the job finding rate exhibit a larger response to productivity shocks during periods with low aggregate...

Using sector-level survey data for the universe of Japanese firms, we establish the positive co-movement in the firm’s expectations about aggregate and sector-specific demand shocks. We show that a simple model with imperfect information on the current aggregate and sector-specific components...

This paper develops a dynamic general equilibrium model with heterogeneous firms that face search complementarities in the formation of vendor contracts. Search complementarities amplify small differences in productivity among firms. Market concentration fosters monopsony power in the labor...

This study provides new insights on the allocative effect of monetary policy. It shows that contractionary monetary policy exerts an important reallocation effect by cleansing unproductive firms and enhancing aggregate productivity. At the same time, however, reallocation involves a reduction in...

We develop a general theory of state-dependent fiscal multipliers in a framework featuring interaction between two empirically relevant goods market frictions: idle productive capacity and unsatisfied demand. Our key novel finding is that the source of economic fluctuations determines the...

This paper develops a dynamic general equilibrium model with heterogeneous firms that face search complementarities in the formation of vendor contracts. Search complementarities amplify small differences in productivity among firms. Market concentration fosters monopsony power in the labor...

Recent empirical evidence establishes that a positive technology shock leads to a decline in labor inputs. Can a flexible price model enriched with labor market frictions replicate this stylized fact? We develop and estimate a standard flexible price model using Bayesian methods that allows, but...
