   The presentation is related to three studies which investigate the causal link from short-term air pollution to a series of novel outcome variables. In particular, (1) sleep quality, (2) cough, and (3) plans to migrate. Each study is based on China, where poor air quality is widely-understood to be an important social issue, focusing on fine particulate matter (PM2.5) and the multi-pollutant Air Quality Index (AQI). For dependent variables in each case, I exploit data derived from internet behavior: In particular search behavior on the very widely-used Baidu search engine and posts on the ubiquitous social media site Weibo. Data is scraped and used to develop pertinent proxies in each case. In each chapter causal claims are bolstered by the use of instrumental variables (IV) methods, in order to address endogeneity concerns. Results in each study are highly statistically significant, prove to be resilient in a wide array of robustness tests and falsification exercises, and are substantial in size. My analysis further broadens and deepens our understanding of the various ways in which the air pollution levels seen in Chinese cities, and in many other parts of the world, can damage human well-being, and identifies previously unaccounted-for benefits of more stringent regulation of air quality.
