d This Stata command implements the changes-in-changes (CIC)
d model proposed by Athey and Imbens (2006). The command estimates
d the average and quantile treatment effects of a treatment in settings
d where repeated cross sections of individuals are observed in a
d treatment group and a control group, before and after the treatment.
d The CIC model relaxes several assumptions of the standard linear
d difference-in-differences model. Both the continuous CIC model
d and discrete CIC model (with and without a conditional independence
d assumption) are included in the cic command, as are treatment effects
d from standard linear difference-in-differences (DID) model and a quantile
d difference-in-differences model. By implementing the CIC estimator
d alongside these other two pre-existing estimators, the command
d can illustrate how the effect the treatment varies across a
d variety of assumptions.
