The "human capital earnings function," in which earnings are expressed as a quadratic in potential experience, is probably the most widely accepted empirical specification in economics. In spite of its widespread acceptance, the human capital earnings function provides a very poor approximation...

Although surveys show that traditional ordering of average wages--i.e. higher earnings with higher schooling and concave age-wage profiles--have not changed during the past three decades, the actual size of the wage differentials measured by education or by work experience has varied from peak...

This paper explores Paul N. Rosenstein-Rodan's idea that simultaneous industrialization of many sectors of the economy can be profitable for them all even when no sector can break even industrializing alone. The authors analyze this idea in the context of an imperfectly-competitive economy with...

This paper considers specialization and the division of labor. A more extensive division of labor raises productivity because returns to the time spent on tasks are usually greater to workers who concentrate on a narrower range of skills. The traditional discussion of the division of labor...

The authors' analysis of growth assumes endogenous fertility and a rising rate of return on human capital as the stock of human capital increases. When human capital is abundant, rates of return on human capital investments are high relative to rates of return on children, whereas, when human...

The authors develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time. Strong addiction to a good requires a big effect of past consumption of the good on current consumption. Such powerful complementarities cause some steady states to be...

A simple supply and demand framework is used to analyze changes in the U.S. wage structure from 1963 to 1987. Rapid secular growth in the demand for more-educated workers, "more-skilled" workers, and females appears to be the driving force behind observed.changes in the wage structure. Measured...
