  More than 200 million people cook with charcoal daily. This has high climate costs: a Kenyan household using a charcoal stove emits as much CO${}_{2}e$ per year as an average U.S. household using a gasoline vehicle. However, concerns around additionality (do subsidies increase sales?) and impact (do sales reduce emissions?) undermine the clean cooking transition. We conduct a randomized trial with 955 households in Nairobi to quantify the additionality and impact of subsidies for an improved cookstove in use by millions of households. Factoring in that 16% of total subsidy spending flows to nonadditional participants, incentivizing one additional stove sale requires US$32 in subsidy spending. Three-and-a-half years later, 83% of buyers own a working improved stove and 11% of nonbuyers do. Factoring in control group adoption and breakage rates, each additional stove generates at least 2.8 additional years of working improved stove ownership. Despite widespread stacking, stove ownership on average abates 1.7 tCO${}_{2}e$ per year. Together, the subsidies abate CO${}_{2}e$ at US$7 per ton (estimates range between US$3.5 and US$8.1). Each dollar of cookstove subsidy abates 168–383 times more CO${}_{2}e$ than a dollar of electric vehicle subsidy.

  Many routine daily activities—such as cooking and commuting—cause large recurring pollution spikes that may impact health without significantly affecting average exposure. We study pollution spikes by combining experimental variation in cooking technology with high-frequency data on individual pollution exposure and time-use in Kenya. Improved cookstoves reduce PM2.5 spikes while cooking by 51.3 μg/m³ (41 percent) and cause a 0.24 standard deviation reduction in self-reported respiratory symptoms. However, even after more than three years of daily use, we find no clinical health improvements, possibly because we detect no impact on average exposure. Clinical health improvements may require reductions in ambient concentrations.

  We study an energy efficient charcoal cookstove in an experiment with 1,000 households in Nairobi. We estimate a 39 percent reduction in charcoal spending, which matches engineering estimates, generating a 295 percent annual return. Despite fuel savings of $237 over the stove’s two-year lifespan—and $295 in emissions reductions—households are only willing to pay $12. Drawing attention to energy savings does not increase demand. However, a loan more than doubles willingness to pay: credit constraints prevent adoption of privately optimal technologies. Energy efficient technologies could drive sustainable development by slowing greenhouse emissions while saving households money.

  We provide descriptive evidence on the challenges in efficiently, effectively, and fairly dis- tributing in-kind electricity transfers to households. We collect panel data from 1,200 households eligible for Ghana’s COVID-19 electricity relief program. Distributing relief through electric- ity transfers enabled an immediate response to the crisis. Theoretical efficiency concerns are mitigated because transfers were inframarginal and storable for most households. Transfer re- ceipt may have increased support for the governing party, possibly due to obfuscation of the program’s financial burden. However, the program was regressive in design, and implemen- tation challenges—delays, technological hurdles, information constraints, and the targeting of meters rather than households—add to inefficiency and regressivity. Households receiving the least average relief are those who use less electricity, pay a landlord or other intermediary for electricity, or share an electricity meter—characteristics of low-income households. Program implementation challenges were just as important as design features in determining program costs and benefits.

  How does temperature affect household energy demand in low-income countries? This paper uses 132,375,282 hourly electricity consumption observations from 5,975 households in South Africa to estimate the causal effects of short-term temperature changes on household electricity consumption. The estimates flexibly identify a constant log-linear temperature response-for every 1°C increase in temperature, electricity consumption decreases by 4.1% among temperatures below the heating threshold but increases by 8.1% among temperatures above the cooling threshold. This relationship is driven more strongly by seasonal than hourly temperature changes. Holding all else constant, a 3.25°C increase in temperatures would reduce electricity consumption by 1,093.4 kWh (6.2%) per year per household. Widespread use of electric heating due to limited residential gas heating infrastructure likely drives this. These results point to important regional heterogeneity in how temperature increases may affect household energy demand in the coming decades.

  The vision of sensor systems that collect critical and previously ungathered information about the world is often only realized when sensors, students, and subjects move outside the academic laboratory. However, deployments at even the smallest scales introduce complexities and risks that can be difficult for a research team to anticipate. Over the past year, our interdisciplinary team of engineers and economists has been designing, deploying, and operating a large sensor network in Accra, Ghana that measures power outages and quality at households and firms. This network consists of 457 custom sensors, over 3,000 mobile app instances, thousands of participant surveys, and custom user incentive and deployment management systems. In part, this deployment supports an evaluation of the impacts of investments in the grid on reliability and the subsequent effects of improvements in reliability on socioeconomic well-being. We report our experiences as we move from performing small pilot deployments to our current scale, attempting to identify the pain points at each stage of the deployment. Finally, we extract high-level observations and lessons learned from our deployment activities, which we wish we had originally known when forecasting budgets, human resources, and project timelines. These insights will be critical as we look toward scaling our deployment to the entire city of Accra and beyond, and we hope that they will encourage and support other researchers looking to measure highly granular information about our world’s critical systems.

• BEPP6110 - Microeconomics for Managers

  This course covers microeconomic foundations for understanding business decision-making. The first unit, “Operating a Firm,” covers demand estimation, cost minimization, and pricing with market power. Unit two, “Markets and Equilibrium,” covers supply and demand, market equilibrium, taxes and tax incidence, and externalities. Unit three presents an introduction to game theory, including simultaneous-move and sequential games. Students are expected to have mastered these materials before enrolling in the second-quarter course, Microeconomics for Managers: Advanced Applications.
