Congratulations Mr. Devarajan this excellent article.
You show that this idea is relevant in "poor" countries. In my opinion, it is also the case for so-called "rich" countries.
To speak only of Europe, I would like to report the existence of a European Citizens' Initiative for Basic Income (ECI), developed by a vast network of individuals and organizations in Europe (independent from any political party), which aim is to urge the European Commission to seriously consider the political and economic option of Basic Income .
There are still two months to get a million signatures needed. A boost from a leading economist of the World Bank would probably be a great help to show the public and policy makers that this idea is not the one of some dreamers but of people watching lucidly the changing world.
