The objective of this project is to identify the Marginal Treatment Effect (MTE) in fuzzy Difference-in-Differences (DiD) settings and to provide a consistent estimator for this treatment parameter. We will derive the MTE in three different settings: (I) the 2x2 DiD setting, where data is divided in two groups and two periods of time; (II) the DiD setting with staggered adoption, where un…
