"This paper uses a model with a continuum of equilibrium unemployment rates to explore the effectiveness of fiscal policy. The existence of multiple steady state unemployment rates is explained by the absence of markets for the inputs to a search technology for matching unemployed workers with...

Davig and Leeper (2007) have proposed a condition they call the generalized Taylor principle to rule out indeterminate equilibria in a version of the New Keynesian model, where the parameters of the policy rule follow a Markov-switching process. We show that although their condition rules out a...

This paper is about the effectiveness of qualitative easing; a government policy that is designed to mitigate risk through central bank purchases of privately held risky assets and their replacement by government debt, with a return that is guaranteed by the taxpayer. Policies of this kind have...

This paper uses a model with a continuum of equilibrium steady state unemployment rates to explore the effectiveness of fiscal policy. The existence of multiple steady state equilibria is explained by the presence of search and recruiting costs. I use the model to explain the current financial...
