In a monopolistic competition framework, we propose a dynamic model in which capacity underutilization ia a macroeconomic equilibrium feature relying on a diversity of microeconomic situations. Capacity underutilization follows from microeconomic demand uncertainty at the time firms must decide...

This paper analyzes the equilibrium dynamics of an AK-type endogenous growth model with vintage capital. The inclusion of vintage capital leads to oscillatory dynamics governed by replacement echoes, which additionally influence the intercept of the balanced growth path. These features, which...

In a dynamic general equilibrium setup, this paper highlights the role of vintages and creative destruction in business fluctuations. By stressing the forward-looking characteristic of the optimal scrapping rule, we use a standard rational expectations argument to show the constancy of the...
