 :Hi, have a look at WP:RS and WP:PROF. The article you are linking to Esther_Duflo is only a stub class article, basing your article on another article (especially one is at the bottom of the classification scale) is not ideal. If you want to see what a Good Article should look like see WP:GA. Also he shouldn't just be mentioned in passing, the sources should talk about him. ~~   "
