"We analyze optimal monetary policy in an endogenous sticky price model. Similar models with exogenous sticky prices can deliver multiplicity of equilibria. Multiplicity of equilibria is a necessary condition for expectation traps to explain the variation across time and countries of inflation...

"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 which can account for this key regularity. My...

We study nominal GDP targeting as optimal monetary policy in a simple and stylized model with a credit market friction. The macroeconomy we study has considerable income inequality, which gives rise to a large private sector credit market. There is an important credit market friction because...

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...
