In a static setup, migration of unskilled labor may be resisted by the entire native-born population because, being relatively low earners, migrants are net beneficiaries of the fiscal system. However, the paper shows that with a pay-as-you-go pension, an important pillar of the welfare state,...

This paper links business cycle volatility to barriers on international mobility of goods and capital. Theory predicts that capital market integration should lower consumption volatility while raising investment volatility, if most shocks are country-specific and transitory. The removal of...

In a world economy there are two types of distortions which can be caused by capital income taxation in addition to the standard closed-economy wedge between the consumer-saver marginal intertemporal rate of substitution and the producer-investor marginal productivity of capital:...

It is often argued that tax competition may lead to a "race to the bottom". Such a race may hold indeed in the case of the pure case of factor mobility (such as capital mobility). However, in this paper we emphasize the unique feature of labor migration, that may nullify the "race to the bottom"...

The pay-as-you-go social security system, increasingly burdened by dwindling labor force, can benefit from immigrants whose birth rates exceed those of the native born birth. The paper examines adynamic political-economy mechanism through which the social security system influences the young...

This paper develops a model of an open economy which employs distortionary taxes to finance public consumption, and with an access to the world capital market. The paper examines the efficiency of quantity restrictions on capital exports and the accompanying set of taxes. A distinction is made...
