摘要：We examine the reduced-form relationship between per capita income and various environmental indicators. Our study covers four types of indicators: urban air pollution, the state of the oxygen regime in river basins, fecal contamination of river basins, and contamination of river basins by heavy metals. We find no evidence that environmental quality deteriorates steadily with economic growth. Rather, for most indicators, economic growth brings an initial phase of deterioration followed by a su...

摘要：According to endogenous growth theory, permanent changes in certain policy variables have permanent effects on the rate of economic growth.

Otherwise, the growth model is inconsistent with time series evidence. This p...

摘要：The paper investigates, both theoretically and empirically, the private demand for STD testing and for protection against infection with emphasis on testing for the AIDS virus (HIV) and on the effects of public subsidies for such testing on the incidence of sexually transmitted diseases. We discuss the theoretical conditions under which subsidizing testing either increases or decreases disease incidence and provide evidence on the empirical significance of those conditions.
