Economists and demographers have long argued that fertility differs by income (differential fertility), and that social security creates incentives for people to rear fewer children. Does the effect of social security on fertility differ by income? How does social security change the...

The standard search model of unemployment predicts, under plausible assumptions about household preferences, that disembodied technological progress leads to higher unemployment. This prediction is at odds with the experience of industrialized countries in the 1970s. This paper shows that...

Unlike in Asia, the manufacturing sector has not (yet) become a driver of structural change in Africa. One common explanation is that the natural resource-focus of many African economies leads to Dutch disease effects. To test this argument for the case of newly found oil in Ghana we develop a...

This paper studies the impact of financial openness on the size of government, and other key economic variables, such as the consumption-wealth ratio, the growth rate of wealth, and welfare, in a two-country world, based on a portfolio approach, assuming that public spending is...

A recent paper by Dollar and Kraay (2001) finds that higher primary educational attainment of the workforce does not increase the income of the poor except for its effect on average income. We test the robustness of their finding by using a broader measure of human capital that accounts for...

The paper surveys the literature on the effects of finance on productivity growth. In both the theoretical and empirical literature, there is no consensus regarding the contribution of financial liberalization and financial development to growth. Focusing on the direct channels of growth, the...

Contemporary policy debates on the macroeconomics of resource booms often concentrate on the short-run Dutch disease effects of public expenditure ignoring the possible long-term effects of alternative revenue-allocation options and the supply-side impact of royalty-financed public investments....

This paper develops a model for analyzing the costs and benefits of intellectual property enforcement in LDCs. The North is more productive than the South and is the only source of innovator. There are two types of goods, and each bloc has a comparative advantage in producing a specific type of...

We investigate the controversial issue whether unemployment is related to productivity growth in the long run, using U.S. data in a framework of infrequent mean shifts. Tests find (endogenously dated) shifts around 1974, 1986, and 1996, system techniques indicate that the shifts are common...
