For my first two years in my PhD program, I was on a fellowship through the Mercatus Center. It looks like they have just started an excellent program for people who want a Masters degree in economics. Tyler Cowen has more:
George Mason University has a new program for people who want a Masters in economics -- not a Ph.d. -- and wish to apply their knowledge to the real world. The value of the scholarship award is up to $80,000 (over two years); more information, including contact information, is here. The application deadline is March 15. Good bloggers, by the way, tend to be good teachers!
