Migrants, being relatively low earners, are net beneficiaries of the welfare state. However, this paper uses a dynamic model to show that because of migrants’ positive influence on the pension system, which is an important pillar of any welfare state, migration could be beneficial to all...

A tax on gross assets has been introduced in some developing countries where several factors (most notably, high inflation) enabled apparently viable enterprises to report losses for income tax purposes. The idea of a tax on the value of assets, rather than on the income that the assets...

Public-private partnerships (PPPs) involve the supply by the private sector of infrastructure and services deriving from infrastructure assets which have traditionally been supplied by the public sector. PPPs are spreading all over the world. It may be quite plausible that such arrangements were...

The extent of taxation and redistribution policy is generally determined at a political-economy equilibrium by a balance between those who gain and those who lose from a more extensive tax-transfer policy. In a stylized model of migration and human capital formation, we find, somewhat against...

We examine the extent to which developing countries that do little, if any, research and development themselves benefit from R&D that is performed in the industrial countries. By trading with an industrial country that has a large “stock of knowledge” from its cumulative R&D activities, a...

The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and...

This paper distinguishes between debt and equity flows in the presence of information asymmetry between the firm’s “insiders” and “outsiders” in a small open economy. It shows the inadequacy of capital investment because its scope is too narrow and the investment each firm makes is too...

We develop a simple information-based model of FDI flows. On the one hand, the abundance of ""intangible"" capital in specialized industries in the source countries, which presumably generates expertise in screening investment projects in the host countries, enhances FDI flows. On the other...

The implication of increasing dependency ratios for pay-as-you-go, defined-benefit pension programs are examined. Modifications aimed at smoothing contributions while maintaining benefits intact are analyzed for both open and closed economies

Data for the United States and countries in Western Europe indicate a negative correlation between the dependency ratio and both labor 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...
