The problem of economic development,' as Lucas (1988) states it, is the problem of accounting for the observed diversity in levels and rates of growth of per capita income across countries and across time. We study conditions under which capital mobility and labor mobility (two seemingly...

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,...

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...

The paper provides a reconciliation of Lucas' paradox, based on fixed setup costs of new investments. With such costs, it does not pay a firm to make a small' investment, even though such an investment is called for by marginal productivity conditions. Using a sample of 45 developed and...

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...

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...
