We study the evolution of the distribution of assets in a discrete time, de-terministic growth model with log-utility, a minimum consumption require-ment, Cobb-Douglas technology, and agents differing in initial assets. We prove that the coefficient of variation in assets across agents decreases...

In dynamic settings with public capital, it is common to assume that the government claims a constant fraction of public investment to total output each period, which is clearly a restrictive assumption. The goal of the paper is twofold: first, to find out a more reasonable rule for public...

This paper devises a fiscal policy by means of which the first-best optimum equilibrium is attained as a market equilibrium in the Uzawa-Lucas model when average human capital has an external effect on productivity. The optimal policy requires the use of a subsidy to investment in human capital...

Two countries are populated by workers and capitalists. Their governments collect taxes to finance productive expenditure and income redistribution. The share of income redistributed defines the size of the welfare state. Although both groups benefit from an abolition of the welfare state in the...

This paper demonstrates that the steady-state solution of the optimal-growth problem in Romer's (1990) model of endogenous technological change is globally saddle-point stable. Surprisingly, the proof of this result is trivial. Interest in the optimal growth path is justified by the fact that...
