WebAug 11, 2024 · Estimation is similar to that for one-way fixed effects, for which a within transformation is used to convert the problem to OLS regression. For two-way models under the general case of unbalanced data, the within transformation is more complex. Following Wansbeek and Kapteyn and Baltagi (2013, sec. 9.4), let Web6. When treatment effects change (monotonically) over time, the DD estimate is biased away from the sign of the true effects. 2. It happens because the treatment effects themselves put units on a differential trend. They are no longer good control units terms that compare “switchers” to “already treated” units are biased. 7. alcudia fahrradtouren https://jonnyalbutt.com
