Econ Master's: Columbia/Duke/Yale

Hello folks. I got into 3 very good programs and need some reassurance I made the right decision. My plan is to work in a Think Tank or in a research-based organization in the future, perhaps even IMF or World Bank. I'm not sure if I'll be needing a PhD for that, but I imagine so. Based on this, which of the 3 options fit the best?

1. Columbia - M.A. Economics (total tuition cost is $70k, no funding).

2. Duke - M.A. Analytical Political Economy (total cost was $115k but I got an 80% scholarship so it's $25k now!)

3. Yale - M.A. International Development and Economics (total tuition is $55k but only 9 months long).

I've chosen Duke since Duke provided me an amazing amount of funding and has a very unique program. Plus the director is Timur Kuran, someone whose research is very relevant to mine.

But I'm reconsidering my options now. Duke's program isn't STEM so as an international student I'll not have the 2-year additional OPT that I might with Columbia's and Yale's STEM programs. But that might not matter anyways if I do go for PhD. What do you think would be the best decision here given my career aspirations? I wouldn't mind going into academia either. Thank you!
