Knowledge that Transforms

Many states are implementing school-finance reforms which will have complex effects on income distribution, intergenerational income mobility, and welfare. This paper analyzes the static and dynamic effects of such reforms by constructing a dynamic general equilibrium model of public-education provision and calibrating it using U.S. data. The authors examine the consequences of a reform of a locally financed system to a state-financed system which equalizes expenditures per student across districts. They find that this policy increases both average income and the share of income spent on education. Steady-state welfare increases by 3.2 percent of steady-state income.

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.
