What are the effects of demographic changes on the real interest rate in Japan? We present a dynamic general equilibrium model in which demographic changes are captured by exogenous changes in the ratio of workers to the total population. Our model predicts that a decline in this ratio in the...

This paper quantifies the role of alternative shocks in accounting for the recent declines in Japanese saving rates and interest rates and provides some projections about their future course. We consider three distinct sources of variation in saving rates and real interest rates: changes in...

We provide a quantitative theory of deflation and secular stagnation. In our lifecycle framework, an aging population puts persistent downward pressure on the price level, real interest rates, and output. A novel feature of our theory is that it also recognizes the reactions of government...
