Abstract:
We study the properties of an overlapping generations model with many-period-lived agents, neoclassical production and capital accumulation, labor-leisure decisions, population growth, and technological progress. We demonstrate that a plausibly calibrated version of this model has "monetary steady states" -Samuelson-case steady states with large real stocks of unbacked government debt. These steady states can duplicate a number of important features of U.S. postwar data, including three phenomena that challenge other sorts of calibrated models: the low average real interest rate on U.S. government debt, the government's success in reducing the debt/GDP ratio without running large budget surpluses and the relatively high ratio of net saving to output.
