Population aging puts significant pressure on social security systems that are based mainly on a pay-as-you-go (PAYG) formula and determined by the political process in which both retirees and future retirees participate. This paper demonstrates that in an economic and demographic steady state,...

This paper interprets contagion effects as an increase in the volatility of aggregate shocks impinging on the domestic economy. The implications of this approach are analyzed in a model with two types of credit market imperfections: domestic banks borrow at a premium on world capital markets,...

This paper examines the effect of skill-biased technological change on the structure of wages, the composition of employment and the level of unemployment in a two-sector economy with a heterogenous work force. Efficiency wage considerations and minimum wage legislation lead to labor market...

This paper analyzes the macroeconomic effects of fiscal and labor market policies in developing countries. The basic framework considers a small open economy with a large informal production sector and a heterogeneous work force. The labor market is segmented as a result of efficiency...

The paper characterizes the feasibility of economic transformation as requiring the simultaneous attainment of macroeconomic stability, political support, and adequate private investment. Macroeconomic stability is defined as fiscal balance; political feasibility is related to the income gains and...

Starting with Friedman and Mundell the academic literature has conducted a high level debate concerning the design of cross-country monetary arrangements. That debate has become very complex and the data requirements necessary for appropriate application of the principles developed are far...

This paper examines the effect of trade reform on wages and unemployment in a two-sector, three-good economy in which labor is imperfectly mobile across sectors. Wages in the export sector are set so as to minimize turnover costs. The analysis shows that a reduction in tariffs, coupled with an...

This paper investigates the factors determining the impact of exchange rate regimes on the behavior of domestic investment and foreign direct investment (FDI). Producers may diversify internationally in order to increase the flexibility of production. We characterize the possible equilibria in a...

This paper compares the importance of precautionary and mercantilist motives in the hoarding of international reserves by developing countries. Overall, empirical results support precautionary motives; in particular, a more liberal capital account regime increases international reserves....
