This paper studies the dynamics between intra-household bargaining power and HIV prevention from a systemic perspective, using a panel data set of 500 married couples in rural Malawi from 2004-2008. All information has been matched at the couple level, which allows to directly assess the effect...

We conduct a field experiment to study if student counseling offices discriminate against disabled students based on their impairment. The offices receive randomized emails from fictitious high-school graduates, requesting information on the admission process and special accommodations to ease...

Condom use and communication among sexual partners are important strategies for HIV prevention. Using a panel data set of more than 1,200 married women in rural Malawi from 1998-2008, this paper shows that adequate HIV prevention strategies, i.e. condom use within marriage and HIV-related...

How does family wealth affect children's development in the short- and long-run? We address this question by exploiting a shock occurred to family’s real estate, i.e. housing damages caused by a super typhoon. Our identification strategy is based on a comparison of children, who all lived in...

We study health care premium subsidies in the Swiss cantons in order to understand the reasons behind the substantial cross-cantonal variation in households' premium load, i.e., the share of disposable income that is spent on premiums after the subsidy. Cantons' financial situation is of...

Using a simulation design that is based on empirical data, a recent study by Huber, Lechner and Wunsch (2012) finds that distance-weighted radius matching with bias adjustment as proposed in Lechner, Miquel and Wunsch (2011) is competitive among a broad range of propensity score-based estimators...

In this note, we show that the OLS and fixed-effects (FE) estimators of the popular differ-ence-in-differences model may deviate when there is time varying panel non-response. If such non-response does not affect the common-trend assumption, then OLS and FE are consistent, but OLS is more...

Most sample selection models assume that the errors are independent of the regressors. Under this assumption, all quantile and mean functions are parallel, which implies that quantile estimators cannot reveal any (per definition non-existing) heterogeneity. However, quantile estimators are...

This survey gives a brief overview of the literature on the difference-in-difference (DiD) estimation strategy and discusses major issues using a treatment effect perspective. In this sense, this survey gives a somewhat different view on DiD than the standard textbook discussion of the...
