ABSTRACT
While taller workers are regularly observed to earn more, there is debate concerning the independent contribution of stature to labor earnings. This study investigates the degree to which the association of height and earnings in Pakistan is independent of other cognitive and socio-emotional skills. Next, the relationship between height and earnings is explored when measures of cognitive ability and an index of socio-emotional capacity are included separately. The paper finds only a modest attenuation in the contribution of height to earnings after controlling for additional dimensions of human capital, suggesting that height provides independent information on labor productivity. This result is robust to treating height as endogenous. The paper also examines non-linearities in the relationship between height and earnings. In contrast to results from relatively few other contributions to research on this non-linear relationship, height is associated with earnings only when an individual is taller than the median height. This lends some support to the role of status and confidence in the yet unresolved question as to the relative contribution of direct and indirect influence of height on earnings.

Marriages between blood relatives-also known as consanguineous unions-are widespread in North Africa, Central and West Asia, and South Asia. Researchers have suggested that consanguinity has adverse effects on child development, but assessing its impact is not straightforward, as the decision to marry a relative might be endogenous to other socio-economic factors. Using a unique data set collected in rural Pakistan, this paper assesses the extent to which consanguinity is linked to children's cognitive and physical development. It exploits grandfathers' land ownership (current and past) and maternal grandparent mortality to identify the effect of endogenous consanguinity on child development. Children born into consanguineous unions have lower cognitive scores, lower height-for-age, and a higher likelihood of being severely stunted. More importantly, adverse effects are greater after accounting for the endogeneity of consanguinity, suggesting that impacts on child development are substantial, and likely to be larger than suggested in previous studies.

This paper uses longitudinal survey data from Taiwan to investigate the predictors of elderly mortality. The empirical analysis confirms a relationship between socioeconomic characteristics and mortality, but this relationship weakens considerably when estimates are conditional on the health status at the time of the first wave survey. In terms of predictive power, the models with an activities of daily living index fare better (as opposed to models with self-evaluated health or self-reported illnesses). Having said that there is a payoff to the consideration of self-evaluated health jointly with other 'objective' health indicators. Other findings include a strong association between life satisfaction and survival, which prevails even after controlling for other explanatory variables.

Local health departments (LHDs) play a key role in the provision of public health services in the United States. Little is known about the extent to which LHD service availability varies by the socioeconomic characteristics of regional populations. This study merges data from the 1996 National Association of County and City Health Officials LHD profile survey and the Area Resource File system. The empirical analysis suggests that LHDs in low-socioeconomic background counties are more likely to provide services such as family planning. For other services, either LHD involvement is low across the board or the distribution of LHD services does not favor low-socioeconomic background counties. Thus, there is often room for improvements in service availability and targeting.
