This paper analyzes the determinants of health insurance enrollment and health expenditure in Ghana using micro data from wave 7 of the Ghana Living Standards Survey (GLSS 7) with emphasis on the role of risk preferences and the availability of health facilities in one's own community. It is...

How malleable is alcohol consumption? Specifically, how much is alcohol consumption driven by the current environment versus individual characteristics? To answer this question, we analyze changes in alcohol purchases when consumers move from one state to another in the United States. We find...

Bias among health care providers can lead to poor-quality care and poor health outcomes, and it can exacerbate disparities. We use a randomized controlled trial to evaluate an intervention to reduce family planning provider bias towards young women in 227 clinics in Tanzania, Burkina Faso, and...

The Food and Drug Administration has proposed to prohibit menthol cigarettes, which are smoked by almost 19 million people in the U.S. Illegal markets for menthol cigarettes could not only blunt the prohibition's intended consequence to reduce smoking but could also lead to unintended...

Nutritional disparities across socioeconomic groups contribute to health inequality in the U.S. This paper studies the role of heterogeneous consumer preferences in food choices and explores pricing policies that can promote healthier eating among disadvantaged consumers. Using detailed...

Causal inference methods are widely used in empirical research; however, there is a paucity of evidence on the properties of shared latent factor estimators in the presence of contaminated instrumental variable (IV) when a strong IV may not be available. We present a theoretical formulation to...

We derive general, yet simple, sharp bounds on the size of the omitted variable bias for a broad class of causal parameters that can be identified as linear functionals of the conditional expectation function of the outcome. Such functionals encompass many of the traditional targets of...

We revisit the identification argument of Kirkeboen et al. (2016) who showed how one may combine instruments for multiple unordered treatments with information about individuals' ranking of these treatments to achieve identification while allowing for both observed and unobserved heterogeneity...

This paper considers the problem of making inferences about the effects of a program on multiple outcomes when the assignment of treatment status is imperfectly randomized. By imperfect randomization we mean that treatment status is reassigned after an initial randomization on the basis of...

This article provides empirical researchers with an introduction and guide to research designs based on variation in judge and examiner tendencies to administer treatments or other interventions. We review the basic theory behind the research design, outline the assumptions under which the...
