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...

The purpose of this paper is to conduct a theoretical and empirical analysis of the nexus between long-term care insurance (LTCI), formal care, informal (family) care, and bequests. In our empirical analysis, we use micro data from the Japan Household Panel Survey on Consumer Preferences and...

We study habitual brand loyalty, one of the earliest empirically-studied forms of switching costs and a classic source of structural state-dependence in consumer demand. Auxiliary instruments and economically-motivated restrictions can tighten nonparametric bounds on the extent of brand loyalty...

Does mental accounting matter for total consumption expenditures? We exploit a unique setting in which individuals exogenously received a new credit card, without requesting one. Using random variation in the time of receipt we show that individuals temporarily increase total consumption...

We use an experiment to test whether consumers optimally acquire information on energy costs in appliance markets where, like many contexts, consumers are poorly informed and make mistakes despite freely-available information. We find consumers acquire information suboptimally; there is little...

Economists have long been ambivalent about whether the discipline should focus on the analysis of markets or should be concerned with social interactions more generally. Recently the discipline has sought to broaden its scope while maintaining the rigor of modern economic analysis. Major...

Customs data reveal heterogeneity and granularity of relationships among buyers and sellers. A key insight is how more exports to a destination break down into more firms selling there and more buyers per exporter. We develop a quantitative general equilibrium model of firm-to-firm matching that...

In this essay I discuss potential outcome and graphical approaches to causality, and their relevance for empirical work in economics. I review some of the work on directed acyclic graphs, including the recent "The Book of Why," ([Pearl and Mackenzie, 2018]). I also discuss the potential outcome...

Over the last two decades, there has been a surge of opioid-related overdose deaths resulting in a myriad of state policy responses. Researchers have evaluated the effectiveness of such policies using a wide-range of statistical models, each of which requires multiple design choices that can...

Despite robust growth in real per capita GDP over the last three decades, the U.S. poverty rate has changed very little. In an effort to better understand this disconnect, we document and quantify the relationship between poverty and four different factors that may affect poverty and its...
