    This is a great illustration of human and environmental factors at work in economics.

    The Economist's Big Mac index is based on the theory of purchasing-power parity (PPP), the idea that exchange rates should move to equalise the prices of a basket of goods and services across different countries. Our basket is the Big Mac. For example, the cheapest burger in the chart is in China, at $1.26, compared with an average American price of $3. This implies that the yuan is 58% undervalued relative to its Big Mac dollar-PPP. On the same basis, the euro is 25% overvalued, the yen 17% undervalued.


    Q. So what is the "True Value" of a big mac?
    A. Depends how hungry you are...
