In this paper we characterize the average response of output to aggregate demand shocks in an economy where individual firms follow state-dependent pricing rules. We find that: (i) the average response of output to aggregate demand shocks decreases with core inflation and varies...

The basic premise of this paper is that understanding aggregate dynamics requires considering that agents are heterogeneous and that they do not adjust continuously to the shocks they perceive. We provide a general characterization of lumpy behavior at the microeconomic level in terms of an...

In this paper we provide a framework to study the aggregate dynamic behavior of an economy where individual units follow (S,s) policies. We characterize structural and stochastic heterogeneities that ensure convergence of the economy's aggregate to that of its frictionless counterpart, determine...

When firms face menu costs, the relation between their output and money is highly nonlinear. At the aggregate level, however, this needs not be so. In this paper we study the dynamic behavior of a general equilibrium menu-cost economy where firms are heterogeneous in the shocks they perceive,...
