<p>Given your background and interests, you might want to consider a master's degree in public affairs/administration. Examples include the LBJ School (UT Austin), Kennedy School (Harvard), and Maxwell School (Syracuse). Those were the three Moody's used to recruit from (and probably still does) for their municipal analysts so happen to be the schools I know best. I'm sure there are lots of others. The LBJ School, where I went, has a huge emphasis on international jobs and places people in all kinds of interesting work environments. </p>
<p>An MPA is like an MBA for folks with an interest in government or public policy. Cost-benefit analysis exercises will do things like require a value to be assigned to a scenic view or a human life, but otherwise have the same approach as business school in terms of training and will give you excellent marketability within the non-profit sector. In my experience, public policy schools also tend to be more generous with scholarships than MBA programs.</p>
<p>I know it is easier to relax when you have a long-term plan that you feel good about even if you change it ten times. Good luck with your explorations.</p>
