Knowledge that Transforms

The author considers trade between a flexible-wage America and a rigid-wage Europe. In a benchmark case, a move from autarky to free trade doubles European unemployment. American wages rise to the European level. Entry of the unskilled 'South' to world markets raises European unemployment. Europe's commitment to the high wage wholly insulates America from the shock. Immigration to America raises American income, but lowers European income dollar for dollar, while European unemployment rises. Absent South-North migration of the unskilled from 1970-90, Europe could have maintained the same wage with from one-eighth to one-fourth less unemployment.

The 1990 Clean Air Act Amendments initiated the first large-scale use of the tradable permit approach to pollution control. The theoretical case for this approach rests on the assumption of an efficient market for emission rights. The authors' empirical analysis shows that the emission rights market created by the 1990 Amendments had become reasonably efficient by mid-1994. They also show that the auctions specified in the Amendments to jump-start trading had become a small part of the overall market. Finally, the authors demonstrate that the strategic bidding behavior discussed in the literature has had no effect on market prices.

In our earlier work, we used data from the National Health Interview Survey (NHIS) to examine life-cycle patterns in health status and in the joint distribution of health status and income (Deaton and Paxson, 1998). In this paper we summarize and extend those results, and provide new evidence from the Panel Study of Income Dynamics (PSID). Both surveys contain a measure of household income, and collect information on an ordinal measures of self-reported health status (SRHS) that ranges from 1 (excellent) to 5 (poor). Section I concerns problems related to the measurement of inequality in health. Section II presents evidence from the two surveys on health and income inequality.

Between 1971 and 1996 opponents of local funding for public schools successfully challenged the constitutionality of school-finance systems in sixteen states. Using the variation across states in the timing of these cases the authors investigate the impact of reform on the distribution of school resources. Their results suggest that court-ordered finance reform reduced within-state inequality in spending by 19 to 34 percent. Successful litigation reduced inequality by raising spending in the poorest districts while leaving spending in the richest districts unchanged, thereby increasing aggregate spending on education. Reform led states to fund additional spending through higher state taxes.

The transition to a market economy has produced a substantial and rapid change in the wage structure in Russia. Household surveys taken before and after the transition indicate that overall wage inequality nearly doubled from 1991 to 1994 and has reached a level higher than that in the United States. Returns to both measured skills (education, occupation) and unmeasured skills within groups have increased considerably. Skill premiums across experience groups, however, have become more compressed and relative wages of older workers have declined. In addition, female wages have declined relative to male wages across all percentiles of the wage distribution.

Conventional wisdom holds that the social rate of return to R&D significantly exceeds the private rate of return and, therefore, R&D should be subsidized. In the U.S., the government has directly funded a large fraction of total R&D spending. This paper shows that there is a serious problem with such government efforts to increase inventive activity. The majority of R&D spending is actually just salary payments for R&D workers. Their labor supply, however, is quite inelastic so when the government funds R&D, a significant fraction of the increased spending goes directly into higher wages. Using CPS data on wages of scientific personnel, this paper shows that government R&D spending raises wages significantly, particularly for scientists related to defense such as physicists and aeronautical engineers. Because of the higher wages, conventional estimates of the effectiveness of R&D policy may be 30 to 50% too high. The results also imply that by altering the wages of scientists and engineers even for firms not receiving federal support, government funding directly crowds out private inventive activity.
