We establish identifying assumptions and estimation procedures for the ATT in a Difference-in-Differences setting with staggered treatment adoption in the presence of spillovers. We show that the ATT can be estimated by a simple TWFE method that extends the approach of Wooldridge [2022]'s fully...

This paper develops a simulation estimation algorithm that is particularly useful for estimating dynamic panel data models with unobserved endogenous state variables. The new approach can easily deal with the commonly encountered and widely discussed initial conditions problem, as well as the...

Theories in political economy depend critically on assumptions about motivations of politicians. Our analysis starts from the premise that politicians, like other economic agents, are rational individuals who make career decisions by comparing the expected returns of alternative choices. The...
