We construct a vintage capital model of economic growth in which the decision to replace old technologies with new ones is modeled explicitly. Depreciation in this environment is an economic, not a physical concept. We describe the balanced growth paths and the transitional dynamics of this...

This paper develops a dynamic industry model in which firms compete to acquire customers over time by disseminating information about themselves under the presence of random shocks to their efficiency. The properties of the model’s stationary equilibrium are related to empirical regularities...

Electricity was born at the dawn of the last century. Households were inundated with a flood of new consumer durable goods. What was the impact of this consumer durable goods revolution? It is argued here that the consumer goods revolution liberated women from the home. To analyze this...

Electricity was born at the dawn of the last century. Households were inundated with a flood of new consumer durables. What was the impact of this consumer durable goods revolution? It is argued here that the consumer goods revolution was conducive to liberating women from the home. To analyse...

This paper introduces a model to analyze the role of the cost of information dissemination in large markets where firms have varying degrees of intrinsic efficiency reflected in their marginal costs. Firms enter a market and discover how efficient they are. Those firms with high enough...
