Hello.
I want to conduct an impact assessment study from a randomised sample and no baseline data. Having read literature, I became confused as I realised that some authors tend to combine the two approaches (ESR and PSM). What is the best model to use?
Your comments will be useful please.
Thanks.
Hi Kalat,
I suggest you checking for the following link to address your issue:

However, some recommendation about "The Importance of Covariate Selection in Controlling for Selection Bias in Observational Studies" is available from: http://www.ipr.northwestern.edu/workshops/past-workshops/quasi-experimental-design-and-analysis-in-education/recent-articles/docs/CovariateSelection08.pdf
Another reference of interest to address your issue, Athey et al., "The Econometrics of Randomized Experiments", 2016: https://www.povertyactionlab.org/sites/default/files/publications/athey_imbens_june19.pdf
Best Regards
