Labor supply theory predicts systematic heterogeneity in the impact of recent welfare reforms on earnings, transfers, and income. Yet most welfare reform research focuses on mean impacts. We investigate the importance of heterogeneity using random-assignment data from Connecticut's Jobs First...

In this paper we propose a variance estimator for the OLS estimator as well as for nonlinear estimators such as logit, probit and GMM. This variance estimator enables cluster-robust inference when there is two-way or multi-way clustering that is non-nested. The variance estimator extends the...

Standard economic analysis suggests that when the budget for redistribution is fixed, income transfers should be targeted to (i.e. means-tested for) those most in need. However, both political scientists and economists long have recognized the possibility that targeting might undermine political...

We investigate the relationship between welfare reform and health insurance, health care utilization, and self-reported measures of health status for women aged 20-45, using nationally representative data from the Behavioral Risk Factor Surveillance System. We present estimates from both...

This paper empirically compares civil procedure in common-law and civil-law countries. Using World-Bank and hand-collected data, and unlike earlier studies that used predecessor data sets, this paper finds no systematic differences between common- and civil-law countries in the complexity,...

This paper argues that the key mechanisms protecting retail investors' financial stake in their portfolio investments are indirect. They do not rely on actions by the investors or by any private actor directly charged with looking after investors' interests. Rather, they are provided by the...

The "antidirector rights index" has been used as a measure of shareholder protection in over a hundred articles since it was introduced by La Porta et al. ("Law and Finance." 1998, Journal of Political Economy 106:1113--55). A thorough reexamination of the legal data, however, leads to...
