We use air pollution exposure measurements and household survey data from four studies conducted across three countries in sub‐Saharan Africa (SSA) to analyze the association between carbon monoxide (CO) exposure from cooking with biomass and indicators of cognitive impairment. While there is strong evidence on the relationship between ambient air pollution exposure and cognitive impairment from studies in high‐income countries, relatively little research has focused on household air pollution (HAP) in low‐income country settings where risks of HAP exposure are high.

IntroductionGlobally, 3–4 billion people rely on solid fuels for cooking, and 1 billion use kerosene to light their homes.

This study investigates the impact of groundwater contamination on educational outcomes in India, using variations in the geographical coverage and timing of safe government piped water schemes. The study is based on survey data from public schools in Assam, one of India’s most groundwater-contaminated regions. It is found that prolonged exposure to unsafe groundwater is linked to increased absenteeism, grade retention, and lower test scores and CGPA. Additionally, the researchers use a nationally representative household survey to study the effect of arsenic contamination.

A robust body of evidence shows that air pollution exposure is detrimental to health outcomes, often measured as deaths and hospitalizations. This literature has focused less on subclinical channels that nonetheless impact behavior, performance, and skills. This article reviews the economic research investigating the causal effects of pollution on nonhealth end points, including labor productivity, cognitive performance, and multiple forms of decision-making.
