This paper studies a general-equilibrium model of a dynamic economy with menu costs. Each firm's productivity is exposed to idiosyncratic and aggregate productivity shocks around a trend, and the money supply to monetary shocks around a trend. All consumption, pricing, and production decisions...

This paper studies a general equilibrium model with multiple stages of production and sticky prices. Working through the input-output relations among industries at different stages and the timing of firms' pricing decisions, the model generates persistent fluctuations in both the inflation rate...

This study focuses on dynamic asset pricing implications for consumption and portfolio shares. First, we exploit the investors' intertemporal budget constraint and the induced national saving identity to construct US total wealth. We then document the empirical shares using aggregate consumption...

The business cycle implications of optimal wage indexation are investigated in a dynamic general equilibrium model with wage contracts. As in Gray's seminal contribution on wage indexation, it is shown that the optimal degree of indexation depends on the relative volatilities of monetary and...
