Gender Differences in Informal Labor Market Resilience (2021), with M Hardy, J McCasland, and G Kagy

This paper documents gender differences in informal labor market resilience using monthly panel data on the universe of garment-making firm owners in a Ghanaian district capital during the 2020 COVID-19 crisis. Although female-owned firms are more likely to close during the spring lockdown period, male- and female-owned firms are equally likely to reopen. Selection into persistent closure differs by gender. Persistently-closed female-owned firms are negatively selected on pre-pandemic sales; their owners experience large decreases in overall income. Persistently-closed male-owned firms are not selected on pre-pandemic firm characteristics; their owners fully compensate for revenue losses with alternative income generating activities.

Is energy the golden thread? A systematic review of the impacts of modern and traditional energy use in low- and middle-income countries (2020), with M Jeuland, TR Fetter, Y Li, SK Pattanayak, F Usmani, and others

Energy has been called the “golden thread” that connects economic growth, social equity and environmental sustainability, but important knowledge gaps exist on the impacts of low- and middle-income country energy interventions and transitions. This study offers perhaps the broadest characterization to date of the patterns and consistency in quantitative and peer-reviewed social science literature considering such impacts. Starting from approximately 80,000 papers identified using a search procedure organized along energy services, technology, and impact dimensions, and structured to achieve breadth and replicability, articles were first screened to yield a relevant subset of 3,000 quantitative papers. Relevance is defined as providing one or more types of impacts on intra-household, household, firm, public service, national economy, or environmental outcomes. A set of heat maps highlights areas of concentration in the literature, namely work that emphasizes the negative health and pollution effects of traditional cooking and fossil fuel use. The extent and consistency of evidence for different types of impacts (in terms of direction and statistical significance) is also discussed, which reveals considerable heterogeneity and highlights important knowledge gaps that remain despite rapidly expanding energy scholarship. The patterns of evidence are also surprisingly consistent across methods. The article concludes by articulating several research challenges that should motivate current and future generations of energy and development scholars.

Returns to rural electrification: Evidence From Bhutan (2019), with SK Pattanayak and T Thinley

Rural electrification (RE) is a core component of the Sustainable Development Goals and a major focal point of the global development community. Despite this focus, more than one billion people worldwide lack access to electricity, and electrification rates need to more than quadruple to meet international goals. We believe that lack of progress is partly driven by a know-do gap, a misalignment between academic research and the information needs of policy makers. Most studies measuring the impacts of electrification focus on precise estimation of a few outcomes, specifically health, education and productivity impacts. Other important impacts, e.g. environmental, have remained largely unstudied. As a consequence, quantifying the full set of costs and benefits of expanding electricity access is difficult and rarely done. When cost benefit analyses are done, they are often incomplete, and conclusions are highly susceptible to unavailable or uncertain parameters. We illustrate these arguments in the case of Bhutan, where RE rates have expanded rapidly in the past few decades. We show that RE via grid extension had positive impacts related to fuelwood consumption, education, and employment, but we do not find an effect on health. We then use these impact estimates to conduct cost-benefit analyses. For the cost-benefit parameters not available from our impact evaluation, we transfer reasonable estimates from related contexts. To acknowledge the uncertainty induced by this process, we conduct Monte Carlo analyses and confirm that, while the private NPV calculations are robust to alternative parameter values, the social returns are sensitive to estimates of the social cost of carbon and costs of grid operation and maintenance. Based on this exercise, we highlight research gaps that persist and that preclude 1) careful cost-benefit analysis of RE more generally and 2) financial investment in the sector.

Through the looking glass: Environmental health economics in low and middle income countries (2018), with SK Pattanayak and E Pakhtigian

In this chapter in the Handbook of Environmental Economics (Volume 4) we examine human–environmental interactions and their implications for health, highlighting the ways in which economic tools provide analytical insight into this relationship as well as potential solutions to preventing (and treating) diseases. Specifically, we contend that the household production framework – which focuses on the beneficiary and households – provides a helpful conceptual tool to understand when and how households will expend resources to avert environmental risks. We review the empirical literature in environmental health economics, focusing particularly on studies that value environmental risk reduction, that examine household adoption of environmental health technologies, and that evaluate health impacts of these technologies. While economists have been mostly on the sidelines of the research on environmental health in LMICs, there is a growing empirical literature on values, drivers, and impacts. This literature reveals considerable heterogeneity in estimates and some methodological blind spots, with sobering overall findings. While there are exceptions to the following observations, we find relatively low values for environmental risk reductions, which is mirrored by limited adoption of environmental health technologies and, accordingly, disappointing results regarding health impacts. Because much remains to be learned about valuation, evaluation, and adoption, we conclude by outlining a research agenda for LMICs that must focus on multiple risks, on the political economy of how interventions are supplied, and on environmental disasters, especially in the light of mounting climate change risks.

Evaluating the impacts of cooking interventions in rural Senegal: The case of domestic biogas digesters (ongoing), with O Ndiaye

In this project, we undertake an impact evaluation of Senegal's Programme National de Biogaz Domestique (PNB-SN), or the national domestic biogas program. PNB-SN aims to support Senegal's energy transition by promoting household use of biogas to meet energy needs. Specifically, the program seeks to reduce the use of solid fuels, like firewood, for cooking and improve agriculture production through the use of bioslurry fertilizer, a bi-product of anaerobic digestion. Using data from household surveys conducted in 2019, we evaluate the impact of PNB-SN on a wide array of household and individual-level outcomes.
