The Economist has constructed a policy room index. It is intended to measure how much monetary and fiscal space economies have to conduct policy. The index has six components: inflation, excess credit (the growth in bank lending minus the growth in nominal GDP), real interest rates, currency movements, current-account balances, and a "fiscal flexibility index." The combine those inputs to produce an overall "wiggle-room index."
This reminds me a lot of another index The Economist put together a few months ago: the overheading index.
I combined the two indices to find which countries are in "most trouble" (i.e. high risk of overheating and little wiggle room). I set the threshold at 70, for both indices. I find that the trouble spots are: Brazil, Argentina, India, Vietnam, and Turkey.
