摘要：The folk theorem of repeated games has established that cooperative behavior can be sustained as an equilibrium in repeated settings. Early papers on private monitoring and a recent paper of Cole and Kocherlakota (Games and Economic Behavior, 53 [2005], 59-72) challenge the robustness of this result by providing examples in which cooperation breaks down when players observe only imperfect private signals about other players' actions, or when attention is restricted to strategies with finite me...

摘要：Why do fertility rates vary so much across countries? Why are European fertility rates so much lower than American fertility rates? To answer these questions we extend the Barro-Becker framework to incorporate the decision to accumulate human capital (which determines earnings) and health capital (which determines life span). We find that cross-country differences in productivity and taxes go a long way toward explaining the observed differences in fertility and mortality.

摘要：We exploit random assignment of gender quotas for leadership positions on Indian village councils to show that prior exposure to a female leader is associated with electoral gains for women. After ten years of quotas, women are more likely to stand for, and win, elected positions in councils required to have a female chief councilor in the previous two elections. We provide experimental and survey evidence on one channel of influence-changes in voter attitudes. Prior exposure to a female chief...

摘要：This paper provides new insight into the relationship between inflation and the setting of individual prices by examining a large data set of Mexican consumer prices covering episodes of both low and high inflation. When the annual rate of inflation is low (below 10%-15%), the frequency of price changes comoves weakly with inflation because movements in the frequency of price decreases and increases partly offset each other. In contrast, the average magnitude of price changes correlates strong...

摘要：Laboratory experiments in psychology find that media violence increases aggression in the short run. We analyze whether media violence affects violent crime in the field. We exploit variation in the violence of blockbuster movies from 1995 to 2004, and study the effect on same-day assaults. We find that violent crime decreases on days with larger theater audiences for violent movies. The effect is partly due to voluntary incapacitation: between 6 P.M. and 12 A.M., a one million increase in the...

摘要：Theory suggests that longer life expectancy encourages educational investment because a longer time horizon increases the value of investments that pay out over time. To estimate the magnitude of this effect, we examine a sudden drop in maternal mortality in Sri Lanka between 1946 and 1953, which sharply increased the life expectancy of girls. We assess whether girls' education relative to boys' increases more in areas with larger maternal mortality declines. We find that for every extra year ...

摘要：In this paper, we use the classical twin design to provide estimates of genetic and environmental influences on experimentally elicited preferences for risk and giving. Using standard methods from behavior genetics, we find strong prima facie evidence that these preferences are broadly heritable and our estimates suggest that genetic differences explain approximately twenty percent of individual variation. The results thus shed light on an important source of individual variation in preference...

摘要：Defaults often have a large influence on consumer decisions. We identify an overlooked but practical alternative to defaults: requiring individuals to make explicit choices for themselves. We study such active decisions in the context of 401(k) saving. We find that compelling new hires to make active decisions about 401(k) enrollment raises the initial fraction that enroll by 28 percentage points relative to a standard opt-in enrollment procedure, producing a savings distribution three months ...

摘要：The nineteenth century witnessed dramatic improvements in the legal rights of married women. Given that they took place long before women gained the right to vote, these changes amounted to a voluntary renunciation of power by men. In this paper, we investigate men's incentives for sharing power with women. In our model, women's legal rights set the marital bargaining power of husbands and wives. We show that men face a trade-off between the rights they want for their own wives (namely none) a...

摘要：We find that genetic distance, a measure associated with the time elapsed since two populations' last common ancestors, has a statistically and economically significant effect on income differences across countries, even controlling for measures of geographical distance, climatic differences, transportation costs, and measures of historical, religious, and linguistic distance. We provide an economic interpretation of these findings in terms of barriers to the diffusion of development from the ...
