To The Economist’s credit, The Big Mac Index is for a large part a
joke. Just think of how many RMB you would have to pay to get a
Big Mac on the moon. It is incredible how much the RMB is overvalued
by that measure. Think about that the next time some clown tells you
that the RMB exchange rate is the cause of all US budget problems.
Robert, my bogus-meter is blinking. Why did you forward an obviously-wrong claim like electricity not being internationally traded?
(And check out DoE and this list of electricity exporting countries.)
