“The result here for the effect of Temporary Protected Status (TPS) on Salvadoran immigrants was a basic D-in-D model, while in the original study it was a basic D-in-D model with control variables. Consult the original study and report the estimated effect of TPS on employment among less-educated Salvadoran woman. How does it compare with the result in Table 3.1 of this chapter? Next, report the findings in this study for another outcome (e.g. hourly wage), and finally for another subsample (e.g. more-educated women). Modify the file script8.R, replicate the published result, and then reanalyze the data by estimating it as a basic D-in-D model. Describe the natural experiment that separates the individuals into control and treatment, and pre- and post-groups. Does the natural experiment provide a plausible way of assigning treatment as if randomly assigned by experimenters?”
