• Resumen

  • Many studies estimate the impact of exposure to some quasiexper-imental policy or event using a panel event study design. These models, as a generalized extension of “difference-in-differences” designs or two-way fixed-effects models, allow for dynamic leads and lags to the event of interest to be estimated, while also controlling for fixed factors (often) by area and time. In this article, wediscuss the setup of the panel event study design in a range of situations and lay out several practical considerations for its estimation. We describe a command,eventdd, that allows for simple estimation, inference, and visualization of event study models in a range of circumstances. We then provide several examples to illustrate eventdd’s use and flexibility, as well as its interaction with various native Stata commands, and other relevant community-contributed commands suchas reghdfe and boottest.
