WebMeasures dynamic effect of permanent change: in time series jargon, measures cumulative response. Typical estimand in time series is impulse response: effect of 1 period change; Common to plot dynamic responses as function of \(e=t-g\), time exposed since treatment, to create event study plot WebLinear regressions with period and group fixed effects are widely used to estimate treatment effects. We show that they identify weighted sums of the average treatment effects (ATE) in each group and period, with weights that may be negative. Due to the negative weights, the linear regression estimand may for instance be negative while all …
