The pay-as-you-go social security system, burdened by dwindling labour force, can benefit from immigrants, with birth rates that exceed the native-born birth rates. Thus, the social security system effectively provides an incentive to liberalize migration policy through a political-economy...

We consider the role of capital mobility and international taxation in explaining the observed diversity in long-term income growth rates. Under perfect capital mobility, international differences in taxes will not matter for total growth differentials. Policy differences have a role to play in...

We provide an exploratory quantitive analysis of the role of capital mobility and international taxation in explaining the observed cross-country diversity in the long-run rates of growth of per capita and total incomes as well as the population growth rates. Corroborative evidence is found for...

We develop a simple information-based model of FDI flows in which the abundance of intangible capital in the source countries, which generates expertise in cream-skimming investment projects in the host countries and enhances FDI flows. Corporate transparency in the host countries, on the other...

The Paper develops a model of foreign direct investments (FDI) and foreign portfolio investments. FDI is characterized by hands-on management style that enables the owner to obtain relatively refined information about the productivity of the firm. This superiority, relative to portfolio...

The New-Keynesian aggregate supply derives from micro-foundations an inflation-dynamics model very much like the tradition in the monetary literature. Inflation is primarily affected by: (i) economic slack; (ii) expectations; (iii) supply shocks; and (iv) inflation persistence. This Paper...

Data for the United States and countries in Western Europe indicate a negative correlation between the dependency ratio and labour tax rates and the generosity of social transfers, after controlling for other factors that influence the size of the welfare state. This is despite the increased...

It has been a remarkably difficult empirical task to identify clear-cut real effects of exchange-rate regimes on the open economy. Similarly, no definitive view emerges as to the aggregate effects of capital account liberalizations. The main hypothesis of the Paper is that a direct and an...

This paper studies sharp reductions in current account deficits and large exchange rate depreciations in low- and middle-income countries. It examines which factors help predict the occurrence of a reversal or a currency crisis, and how these events affect macroeconomic performance. It finds...

It is well known that in the Mundell-Fleming model capital mobility creates a channel through which permanent (transitory) shocks to aggregate demand such as fiscal and trade shocks are completely (partially) neutralized by the response of the real exchange rate. An important policy implication...
