There is continuing debate about what explains cooperation and self-sacrifice in nature and in particular in humans. This paper suggests a new way to think about this famous problem. I argue that, for an evolutionary biologist as well as a quantitative social scientist, the triangle of two...

This paper estimates a model of dynamic intrahousehold investment behavior which incorporates family fixed effects and child endowment heterogeneity. This framework is applied to large American and British survey data on birth outcomes, with focus on the effects of antenatal parental smoking and...

This paper examines the effect of income polarisation on individual health. We argue that polarisation captures much better the social tension and conflict that underlie some of the pathways linking income disparities and individual health, and which have been traditionally proxied by...

A number of researchers point to the anticipation of early death, or a sense of "futurelessness," as a contributing factor to youth crime and violence. Young people who perceive a high probability of early death, it is argued, may have little reason to delay gratification for the promise of...

The magnitude of the effect that health has on the retirement decision has long been studied. We examine the reverse relationship, whether or not retirement has a direct impact on later-life health. In order to identify the causal relationship, we use unexpected early retirement window offers to...

We study the effect of attrition and other forms of non-response on the representativity over time of the Health and Retirement Study (HRS) sample born 1931-1941; the sample was initially drawn in 1992. Although some baseline characteristics of respondents do appear correlated with non-response over...

Both Western and Soviet estimates of GNP growth in the USSR indicate that GNP per capita grew in every decade -- sometimes rapidly -- from 1928 to 1985. While this measure suggests that the standard of living improved in the USSR throughout this period, it is unclear whether this economic growth...

This paper investigates the robustness of recent findings on the effect of parental background on child health. We are particularly concerned with the extent to which their finding that income effects on child health are the result of spurious correlation rather than some causal mechanism. A...

This paper identifies health determinants in urban China applying Grossman model. Using wave of China Health and Nutrition Survey in 2000, we find that education has important positive effect on health, and cost of health care services has significantly negative impact. However, effects of wage...
