WebTWFE: the second comming: You don't mess up with OLS. While traditional TWFE has received a lot of "but's" because its inability of correctly identifying ATT's, the methodology has been defended by Prof Wooldridge. His message is quite simple, but powerful. Yes, TWFE as traditionally applied, has many limitations regarding the estimation of ATTs. WebFinally, it is easy to modify the TWFE estimator to allow for spillover effects. For example, a policy change in county i may have an effect in an adjacent county, h, and this is easily …

WebFeb 20, 2024 · Conclusion. The three core assumptions you need for TWFE to be a consistent estimate of population regression coefficients in a dynamic event study specification like we used above are 1) parallel trends, 2) no anticipation and 3) homogeneous treatment effect profiles. You need all three, not just the first two.
