Government debt can be rolled over forever without primary surpluses in some stochastic economies, including some economies that are dynamically efficient. In an overlapping-generations model with constant growth rate, g, of labor-augmenting productivity, and with shocks to the durability of...

We characterize a planner's optimal allocation of consumption and capital in an overlapping generations model with exogenous government purchases, privately-observed idiosyncratic shocks to the depreciation rate of capital, and a proportional cost of reversing investment to transform used...

This paper develops a tractable stochastic overlapping generations model to analyze the equilibrium equity premium and growth rate of the capital stock in the presence of a defined-benefit Social Security system. If the Social Security Trust Fund increases the share of its portfolio held in...

Recent work demonstrates that dynastic assumptions guarantee the irrelevance of all redistributional polices, distortionary taxes, and prices--the neutrality of fiscal policy (Ricardian equivalence) is only the "tip of the iceberg." In this paper, we investigate the possibility of reinstating...
