Small-scale human societies range from foraging bands with a strong egalitarian ethos to more economically stratified agrarian and pastoral societies. We explain this variation in inequality using a dynamic model in which a population's long-run steady-state level of inequality depends on the extent to which its most important forms of wealth are(More)
At present limited data exist describing the hospital use patterns of intravenous drug users (IVDUs) and women with AIDS. Our objective was to determine if frequency of hospitalization, length of stay (LOS), and cost per hospitalization varied by risk status and gender, controlling for a variety of confounders, including severity of illness as measured by(More)
We report quantitative estimates of intergenerational transmission and population-wide inequality for wealth measures in a set of hunter-gatherer populations. Wealth is defined broadly as factors that contribute to individual or household well-being, ranging from embodied forms such as weight and hunting success to material forms such household goods, as(More)
OBJECTIVE To determine whether there is an association between mortality and hospital acquired immune deficiency syndrome (AIDS) experience for all AIDS-related diagnoses, and to determine whether the association is explained by differences in severity of illness, earlier discharge of terminally ill patients, or differences in resource use. DESIGN AND(More)
The objectives of this study were twofold: to improve methods of identifying possible and acquired immunodeficiency syndrome (AIDS)-related hospital discharges in administrative databases and to measure AIDS-reporting completeness in Massachusetts both overall and by subgroup. We used fiscal year 1988 discharge data from the Massachusetts Rate Setting(More)
This article shows that the burden of certain tropical disease infections, after controlling for other factors, is positively correlated with HIV prevalence. Using cross-national data and multivariate linear regression analysis, we investigate the determinants of HIV prevalence in low- and middle-income countries. We begin with social and economic variables(More)
