this is a research paper I wrote for my economics class. it is an econometric analysis of the impact of Uber's entry on the air quality in US cities. I used Uber entry data and AQI data from the EPA, as well as a difference-in-difference estimation that captures treatement effect heterogeniety using STATA.
the course description follows: "Exposes students to the process of conducting independent research in empirical economics and effectively communicating the results of the research. Emphasizes econometric analysis of an assigned economic question and culminates in each student choosing an original topic, performing appropriate analysis, and delivering oral and written project reports."
