Help me chose an exchange university?

[BuryYourFlame]

I've been thinking about going on exchange starting mid-way through next year. I'm most heavily thinking of going to America but I would be open to other countries as well. I don't speak any other languages and I'm not sure if I would have time to become proficient enough to be taught economics in another language. That being said, there are universities in countries in which English is not the native language where they offer courses taught entirely in English.

My university has these universities in it's exchange listing from what I can see.

California State University, Long Beach
Colorado School of Mines, Golden
Emory University - Goizueta School of Business
Indiana University, Bloomington
Montana State University, Bozeman
North Carolina State University
Northern Arizona University
University of California System
University of Colorado, Boulder
University of Connecticut, Storrs
University of Kansas, Lawrence
University of Massachusetts, Amherst
University of Miami, Florida
University of Nebraska, Lincoln
University of North Carolina System
University of North Carolina, Wilmington
University of Oklahoma
University of Texas at Dallas

Are there any among those that you would particularly recommend for the fields of economics/commerce (or ones that I should avoid)?
Also, are there any other international universities that would be good for the same field?
