    I am currently a PhD student in Economics at University of Pittsburgh with a focus in development, health, and behavioral economics. I have studied the economics of potable water distribution and access in developing contexts, the influence of climate on economic behavior, and the health effects of consumer electronics.

      • The Role of Water Availability in Mitigating Heat-Related Mortality: Empirical Evidence from South Africa

        As the world works toward the Agenda for Sustainable Development goal of universal access to safe drinking water, rising global surface temperatures threaten to reduce precipitation and evaporate surface freshwater in areas already experiencing water stress. In this paper, I provide empirical evidence of a significant interaction between water availability and the heat-mortality relationship. I find that higher upstream water availability reduces the slope of the temperature- mortality relationship during the November to February hot season. I confirm this effect with a number of alternative specifications and robustness checks, including using other months of the year as a comparison group, using upstream water availability as an instrument for local availability, and exploiting the Lesotho Highlands Water Project transfer inaugurated in 2004 as a natural experiment. This suggests that the decrease in precipitation predicted in South Africa (Nkhonjera et al. 2017) and more broadly (Intergovernmental Panel on Climate Change 2014) as a consequence of climate change will amplify the direct effect on mortality of rising temperatures, and must be preempted with substantial investment in technologies to stabilize and augment the supply of potable water.

      • Living Jerrycan to Jerrycan: The Cost of Drinking Water in Urban Nigeria

        Households under water stress in urban Nigeria consider vendors (mairuwas) a “saving grace,” as they provide water with no connection fee or need for pipe construction. However, their desperation, especially during water shortages and electricity blackouts, allows mairuwas to charge 10 to 50 times the utility's wholesale price (Whittington et al. 1991, Nnaji et al. 2013). While the markup per jerrycan appears negligible, in just a few months, a household will have paid enough markup to cover the standard piped water connection fee. From this perspective, vendors exploit liquidity constraints and impatience to divert funds from the public good. To determine vendors’ net contribution to social welfare, I quantify the effect of water vending in urban Nigeria on the cost and accessibility of safe drinking water and associated health consequences.

      • Gender-Specific Shocks & Household Bargaining Power: A Machine Learning Approach To Scanner Data (with Rania Gihleb and Osea Giuntella)

        We examine the effect of several gender-specific labor market shocks documented in the literature on the consumption of heterosexual married couples in the United States. Using machine learning and text analysis techniques, we construct a score of relative gender preference at the product UPC level, culminating in an overall score of each household’s consumption. We find that within households, negative shocks to male labor demand increase the relative share of female-preferred goods, and vice versa, suggesting women gain intra-household bargaining power following these shocks. These effects are mirrored in consumption of children’s goods by gender, suggesting an improved bargaining position for the mother proportionally benefits daughters.

      • Blood and Water: The Effect of Conflict on Sustainable Development

        The goal of this paper is to measure the long-term effects of conflict-associated damage to water infrastructure. Beyond the immediate consequences of households losing a potential source of drinking water, I hypothesize that the destruction of water infrastructure in conflict has persistent long-run effects on an area’s health and economic development. Robust water infrastructure is costly to build, and the money spent on repairing or rebuilding cannot be invested in other catalysts of development such as education, transportation, and internet connectivity. At the same time, repeated or protracted conflict reduces the incentive to invest in long-term infrastructure because of the high probability of damage or destruction, keeping affected areas reliant on transient water sources. As a result, areas mired in conflict may experience worse health outcomes and higher mortality rates than nearby areas the conflict never reached long after the last bullet is fired.
