When economists want to sum all they know on a topic (and all they don’t), they turn to the Journal of Economic Perspectives. It’s easily the most interesting and accessible journal in the profession, and now it’s free online.
The Spring 2010 issue features the econometric greats on the revolution in experimental and empirical economics.
Spring 2009 has a symposium on climate change.
Winter 2009 has look at microfinance.
Spring 2008 has a symposium on development.
