This paper explores a causal link between aging of the labor force and declining trends in the real interest rate and inflation in Japan. We develop a New Keynesian search/matching model that features heterogeneities in age and firm-specific skills. Using the model, we examine the long-run...

This paper explores a causal link between aging of the labor force and declining trends in the real interest rate in Japan. We develop a search/matching model that features heterogeneous workers with respect to their ages and firm-specific skills. Using the model, we examine the long-run...

Does fiscal policy have qualitatively different effects on the economy in a liquidity trap? We analyze a nonlinear stochastic New Keynesian model and compare the true and loglinearized equilibria. Using the loglinearized equilibrium conditions, the answer to the above question is yes. However,...

Does fiscal policy have large and qualitatively different effects on the economy when the nominal interest rate is zero? An emerging consensus in the New Keynesian literature is that the answer is yes. New evidence provided here suggests that the answer is often no. For a broad range of...
