Understanding the roots of human cooperation among strangers is of great importance for solving pressing social dilemmas and maintening public goods in human societies. We study the development of cooperation in 929 young children, aged 3 to 6. In a unified experimental framework, we examine...

This paper documents the persistence of the Southern slave owning elite in political power after the end of the American Civil War. We draw on a database of Texan state legislators between 1860 and 1900 and link them to their or their ancestors' slaveholdings in 1860. We then show that former...

Applications to elite US colleges have more than doubled over the past 20 years, with little change in the number of available seats. We examine how this increased competition has affected the admissions advantage that legacies and athletes (LA) receive. Using data on Harvard applications over...

This paper examines the impact of home country economic status on immigrant self-employment probability in the U.S. We estimate a probability model and find that, consistent across race, immigrants from developed countries are more likely to be self-employed in the U.S than are immigrants from...

"Looking across many diseases, average health among mature men is much worse in America compared to England. Second, there exists a steep negative health gradient for men in both countries where men at the bottom of the economic hierarchy are in much worse health than those at the top. This...

"In the United States happiness, on average, varies positively with socio-economic status; is fairly constant over time; rises to midlife and then declines; and is lower among younger than older birth cohorts. These four patterns of mean happiness can be predicted rather closely from the mean...

"Models of status based on Frank's (1985) count of the number of people with lower conspicuous consumption are inconsistent with the extensive empirical literature on happiness and well-being. The alternative approach to consumption interaction which uses some form of relative income has been...

We investigate the impact of exogenous income fluctuations on health using twenty years of data from the Panel Study of Income Dynamics using techniques from the literature on the estimation of dynamic panel data models. Contrary to much of the previous literature on health and socio-economic...

In this paper we present results of an investigation into observable characteristics associated with attrition in ELSA and the HRS, with a particular focus on whether attrition is systematically related to health outcomes and socioeconomic status (SES). Investigating the links between health and...

We use longitudinal data from the 1984 through 2007 waves of the Panel Study of Income Dynamics to examine how occupational status is related to the health transitions of 30 to 59 year-old U.S. males. A recent history of blue-collar employment predicts a substantial increase in the probability...
