^ Just to add to above, I was researching Yale's IDE course a while back - it seems to be aimed at individuals who will enter development economics in a professional capacity (e.g. the public sector, NGOs). They particularly welcome applicants from developing countries who will, after graduation, go back to said country. They don't offer any programme specific scholarships, (they say they hope that candidates will get funding from their respective country's government/employer). If I remember correctly they actively dissuade IDE students from applying to the Yale economics PhD programme - clearly this is a programme that isn't for wannabe academics.
So avoid Yale's IDE programme, unless you 100% want to work in development economics straight after you finish your Master's.
