I am currently admitted to SAIS (ERE) starting next fall. I am considering applying to Wharton/Tuck/INSEAD for the dual degree MA/MBA program. The joint program would add another year to the degree and be an additional ~$70K plus opportunity costs. If I am interested in energy in the private sector, how much would the MBA improve i) my job prospects, and ii) my salary. In other words, is it worth the costs? As BG, I have 4 years of work experience, 710 GMAT, and 3.8 GPA from a Top 50 undergrad. Thanks!
p.s. I also posted this in the Business forum, but figured you guys would have a much different perspective.
