This paper revisits the case for flexible vs. fixed exchange rate regime in a two-country model with firm heterogeneity and nominal wage rigidity under incomplete financial markets. Dampening nominal exchange rate fluctuations simultaneously stabilizes the firm turnover in the export market....

This paper explores the role played by product variety and quality in a real business cycle model. Firms are heterogeneous in terms of their specific quality as well as pro- ductivity levels. Firms which have costly technology enter in a period of high aggregated demand and produce high quality...

This paper revisits Schumpeterian destruction in a DSGE model based on monopolistic competition. Firms enter the market through a free entry condition and exit endogenously depending on their specific productivity level. The mechanism of endogenous destruction among heterogeneous firms is based...

This paper examines the influence of financial constraints on the transmission of monetary policy shocks across heterogeneous firms. To this end, we develop a Dynamic Stochastic General Equilibrium (DSGE) model incorporating firm heterogeneity, nominal rigidity, and financial frictions....

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