@leon32 Oh that's good to know! I was under the impression that it had to be a traditional thesis - working on something more real-world would definitely be more marketable
@WinterSolstice I've heard the same thing about SIPA (very big, impersonal, not a lot of access to the star professors) which is a definite drawback - I do plan to continue working abroad though which is why I feel the brand makes a bit of a difference.
In terms of being a development practitioner vs an economist, I mean I'm more generally interested in working in the field on the implementation of development projects, with an INGO, the UN, or a USAID contractor, etc. rather than with, say, a development bank on the design of its development policies. I've been working in field level implementation for a couple of years now, and from my experience the skills required are much more related to project management and the pertinent technical sector (WASH, food security, governance, etc.) than economics, unless one is working specifically on economic recovery/development programs. Of course it helps to have a broad understanding of the economic context for perspective, but in my experience it doesn't necessarily inform one's day to day work in this field.
Fletcher does definitely seem to have the strongest humanitarian program which is why I haven't ruled it out, but my interest is sort of in the middle of the humanitarian and development phases since I want to work in post-conflict development, helping to build institutions in contexts recovering from violence. I don't want to work on the purely humanitarian side (handing out food, building camp latrines, etc.) but I don't want to work on fully post-recovery development (expanding businesses, education, etc.) either, so I'm not sure that having the strongest humanitarian program makes a difference when SAIS is overall a better school.
