To be precise, I am looking for studies on informal labour that have taken on board Sanyal's category of the Need Economy and his 'Politics of Exclusion' in studying the political-economy of post-liberalization India/countries in the global south?
I can't suggest any specific studies but it may be worth checking the ILO library. The idea of informal economy arose from ILO research in East Africa in early 1970's, so there may be recent grey literature to be found there.
