Abstract

En 中文

Linear panel models and the event-study plots that often accompany them are popular tools for learning about policy effects. We introduce the xtevent package, which enables the construction of event-study plots following the suggestions in Freyaldenhoven et al. (Forthcoming, Visualization, identification, and estimation in the linear panel event-study design [Cambridge University Press]). The package implements various procedures to estimate the underlying policy effects and allows for nonbinary policy variables and estimation adjusting for preevent trends.
