Precision-Guided or Blunt? The Effects of US Economic Sanctions on Human Rights

We use endogenous treatment-regression models to estimate the causal average treatment effect of US economic sanctions on four types of human rights. In contrast to previous studies, we find no support for adverse effects of sanctions on economic rights, political and civil rights, and basic human rights. With respect to women's rights, our findings even indicate a positive relationship. Emancipatory rights are, on average, strengthened when a country faces sanctions by the US. Our findings are robust when applying various changes to the empirical specification. Most importantly, this study provides strong evidence that the endogeneity of treatment assignment must be modelled when the consequences of sanctions are studied empirically

Income Inequality and Tax Policy for South African Race Groups

This paper calculates elasticities of demand for race groups in South Africa, government-revenue-maximizing tax rates, and excess burdens associated with taxes. A change in tax policy can be the political engine of income redistribution with appropriate taxes and subsidies on different commodities. This paper compares both semiparametric and parametric estimators with the censored least absolute deviation and censored maximum likelihood in calculating demand equations and elasticities. It is found that cigarettes and milk are the two commodities that generate the most government revenues from whites per unit of government revenues from blacks. © 2003 President and Fellows of Harvard College and the Massachusetts Institute of Technology.
