This paper analyses the effects of fiscal policies on rates of interest and wealth in the world economy. Uncertainty concerning the length of life yields an equilibrium in which private and social rates of discount differ and budget deficits exert real effects. It is shown that a current budget...

This paper develops and estimates a dynamic optimizing model of the current account. The model focuses, on real factors that determine the evolution of saving and investment, and hence the external balance. Three types of shocks are at the center of the analysis: productivity shocks, shocks to...

We develop a framework in which the host country productivity has a positive effect on the intensive margin (the size of FDI flows), but only an ambiguous effect on the extensive margin (the likelihood of FDI flows to occur). The source-country productivity has a negative effect on the extensive...

The paper analyzes the effect of the generosity of the welfare state on the skill composition of immigrants. We develop a parsimonious model in which the effect of an increase in the generosity (and taxes) of the welfare state on the skill composition of immigrants under free migration is...

A positive productivity shock in the host country tends typically to increase the volume of the desired FDI flows to the host country, through the standard marginal profitability effect. But, at the same time, such a shock may lower the likelihood of making any new FDI flows by the source...

The paper brings out the special mechanism through which taxes influence bilateral FDI, when investment decisions are two-fold in the presence of fixed setup flows costs. For each pair of source-host countries, there is a set of factors determining whether aggregate FDI flows will occur at all,...

The paper develops a model with lumpy setup costs of new investment, which govern the flows of FDI. Foreign investment decisions are two-fold: whether to export FDI and, if so, how much. The first decision is governed by total profitability considerations, whereas the second is governed by...
