It is well known that rational bubbles can be sustained in balanced growth path of a deterministic economy when the return to capital r is equal to the growth rate g. When there is a lack of stores of value, bubbles can implement an efficient allocation. This paper considers a world where r...

Recent theoretical work shows that folk theorems can be developed for infiniteoverlapping generations games. Cooperation in such games can be sustained as aNash equilibrium. Besides the efficient cooperative equilibrium there is alsothe inefficient non-cooperative equilibrium. This paper...

In this paper we study the implications of population ageing in an economy with a sizeable non-traded goods sector. To this effect a highly stylized micro-founded macro model is constructed in which the age structure of the population plays a non-trivial role. The model distinguishes separate...

Pensions may be provided for in a modern society by several methods, viz., voluntary individual savings, mandatory fully funded occupational pension systems, and mandatory social security financed by pay-as-you-go. The specific mixture of the three systems we will call the pension composition....

The paper examines the effect of heterogeneity in individual human capital formation on cross-country income inequality. It considers a two-country model of overlapping generation heterogeneous economies with the following features: (1) individuals are heterogeneous with respect to inborn...
