摘要:The 1981-1982 recession induced substantial variation across sites in air pollution reductions. This is used to estimate the impact of total suspended particulates (TSPs) on infant mortality. We find that a 1-percent reduction in TSPs results in a 0.35 percent decline in the infant mortality rate at the county level, implying that 2500 fewer infants died from 1980-1982 than would have in the absence of the TSPs reductions. Most of these effects are driven by fewer deaths occurring within one m...

摘要:Even though the provision of equal opportunities for men and women has been a priority in many countries, large gender differences prevail in competitive high-ranking positions. Suggested explanations include discrimination and differences in preferences and human capital. In this paper we present experimental evidence in support of an additional factor: women may be less effective than men in competitive environments, even if they are able to perform similarly in noncompetitive environments. ...

摘要:This paper analyzes a randomized experiment to shed light on the role of information and social interactions in employees' decisions to enroll in a Tax Deferred Account (TDA) retirement plan within a large university. The experiment encouraged a random sample of employees in a subset of departments to attend a benefits information fair organized by the university, by promising a monetary reward for attendance. The experiment multiplied by more than five the attendance rate of these treated ind...

摘要:We use a simple model to outline the conditions under which corporate investment is sensitive to nonfundamental movements in stock prices. The key prediction is that stock prices have a stronger impact on the investment of equity-dependent firms-firms that need external equity to finance marginal investments. Using an index of equity dependence based on the work of Kaplan and Zingales, we find support for this hypothesis. In particular, firms that rank in the top quintile of the KZ index have ...
