An interesting post from a blog held by the World Bank try to give  valid answer as to why LPM could be adopted.

This is a very interesting post, because it might be of help to economists who are stuck with referees who insist on the necessity of changing the LPM into a non-linear model.

I came across this post, and I decided to post it here, because I have had a similar discussion with my supervisors (although I was the one insisting for the LPM), and I feel like in the future I will have many other discussion about the same topic.
