This paper investigates the role that the entry and exit of heterogeneous firms plays in shaping aggregate fluctuations in economic activity. In so doing, it develops a dynamic stochastic general equilibrium model in which procyclical entry and countercyclical exit along a real business cycle...

Feedback from stock prices to cash flows occurs because information revealed by firms' stock prices influences the actions of competitors. We explore the implications of feedback within a noisy rational expectations setting with incumbent publicly traded firms and privately held new entrants. In...

We provide a nonlinear characterization of the macroeconomic impact of microeconomic productivity shocks in terms of reduced-form non-parametric elasticities for efficient economies. We also show how structural parameters are mapped to these reduced-form elasticities. In this sense, we extend...

This paper explores the impact of incomplete markets and strong complementarities on the time series properties of aggregate activity. We consider an economy which consists of a large number of industries whose production functions both are nonconvex and exhibit localized technological...

Economies respond differently to aggregate shocks that reduce output. While some countries rapidly recover their pre-crisis trend, others stagnate. Recent studies provide empirical support for a link between aggregate growth and plant dynamics through its effect on productivity: the entry and...

An analysis of the performance of GDP, employment and other labor market variables following the troughs in postwar U.S. business cycles points to much slower recoveries in the three most recent episodes, but does not reveal any significant change over time in the relation between GDP and...

We use more than one century of Argentine and Mexican data to estimate the structural parameters of a small-open-economy real-business-cycle model driven by nonstationary productivity shocks. We find that the RBC model does a poor job at explaining business cycles in emerging countries. We then...
