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...

This paper investigates the dynamic consequences of demographic change and various pension reform scenarios for Austria. The analysis is based on a computable overlapping-generations model with life-cycle labor supply, savings, and search unemployment. The public sector is decomposed into...

Sustained endogenous growth is known to be impossible in OLG one-sector models without non-convexities and externalities, unless income is redistributed to the young generation. No redistribution proper is however necessary, as shown in two simple examples, if positive profits accruing to young...

This paper analyzes the impact of cyclical volatility on long-term economic growth: does growth increase or decrease with increased cyclical volatility? We construct a stochastic two-sector model of endogenous growth to analyze this question in detail. We will show that economic growth is higher...

It has been believed that a social security system (SSS) is harmful to economic growth. However, it has been recognized recently that a SSS can encourage economic growth if the engine of the growth is human-capital accumulation. This paper uses an analytical model à la Uzawa/Lucas to examine...

The paper studies the local dynamics of an endogenous growth model with externalities of investment. It is demonstrated that, in case of sustained per capita growth, the competitve economy is characterized by a situation with a unique balanced growth path which is saddle point stable or by a...

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...

We develop a geographic growth model where nominal wages are allowed to diverge between the two considered countries. Removing the standard assumption entailing that both countries always own a traditional sector, we argue that, as trade gets freer, the traditional sector of one country might...

This paper builds a model in which the distribution of income matters for capital formation, and uses it to analyze the effects of a simple policy intended to create a more equal distribution of income on the severity of certain credit market imperfections and, through this channel, capital...

This paper analyses a model of overlapping generations in which agents who are not in the labor market are unable to borrow. An increase in a fully funded pension raises aggregate savings since private savings are not crowded out one-for-one. Labor force participation is determined endogenously,...
