We analyze optimal discretionary monetary policy in an endogenous sticky prices model. Similar models with exogenous sticky prices can deliver multiple equilibria. This is a necessary condition for the occurrence of expectation traps (when private agents' expectations determine the equilibrium...

A defining feature of business cycles is the comovement of inputs at the sectoral level with aggregate activity. Standard models cannot account for this phenomenon. This paper develops and estimates a two-sector dynamic general equilibrium model that can account for this key regularity. My model...

This paper evaluates the dynamic response of worker flows, job flows, and vacancies to aggregate shocks in a structural vector autoregression. We identify demand, monetary, and technology shocks by imposing sign restrictions on the responses of output, inflation, the interest rate, and the...

We argue that the Great Inflation experienced by both the United Kingdom and the United States in the 1970s has an explanation valid for both countries. The explanation does not appeal to common shocks or to exchange rate linkages, but to the common doctrine underlying the systematic monetary...

We use structural vector autoregressions to analyze the responses of worker flows, job flows, vacancies, and hours to shocks. We identify demand and supply shocks by restricting the short-run responses of output and the price level. On the demand side we disentangle a monetary and non-monetary...
