I need to write an assignment paper in development economics that explains the concept of differences-in-differences estimation, and I feel like it can certainly be helpful to look at some examples that actually used this method.
So I wish to look for some sample papers which dealt with issues in development economics that used the difference-in-differences method as a reference for the paper.
I spent some time searching for examples but it's been surprisingly difficult to find actual example papers displaying this method (I was only able to find hypothetical examples or examples used in the United States). Maybe there is a problem with my searching method.
Is there a website where I can specifically find examples or sample papers on development economics (so the estimation has to be used in developing countries) that used Differences-in-Differences? I think there are friends here who are used to searching for or writing papers like this, and I would appreciate advice on places to refer to or how to find these kinds of papers that match my needs.
