Over his blog The Beauty Contest – A blog on Spanish and international affairs, macroeconomics and finance, Javier López Bernardo has an analysis of Bernie Sanders’ economic plan (written with his colleague Rafael Wildauer).

Javier López Bernardo and  Rafael Wildauer stress the importance of the U.S. balance of payments constraint on U.S. growth.
