Problem sets

We provide a set of problem sets to revisit selected issues we discussed during class.

Potential outcome model

We explore the potential outcome model using observed and simulated data inspired by the National Health Interview Survey. The accompanying data sets are available here.

Potential outcome model

Matching estimators

We compare the consistency of regression and matching estimators using LaLonde (1986) framework and the Current Population Survey data. The accompanying data sets are available here.

Regression and matching estimators in causal effects

Regression discontinuity design

We practice RDD with Lee (2008) framework. In particular, we illustrate a discontinuity at the cutoff point with local averages graph, estimate treatment effect by local linear regression and choose an optimal bandwidth by cross-validation procedure. The accompanying data sets are available here.
