The Big Mac, a (nearly) perfect form of global currency
Have you ever exchanged your dollars for a different currency? I don't know about you, but I'm always confused as to how much I'm actually getting. If I can trade one dollar for 0.75 euros, can I still get as much stuff as I would with a dollar (which, admittedly, is not that much)?
For over 20 years, The Economist has been giving a clever answer to this complex question: Big Macs. The Economist's Big Mac Index compares the prices of that beloved artery-clogger around the globe, and in the process helps show just how much you can get for your dollar. Or franc. Or rouble. In their latest index, you can get a burger in the U.S. for about $3.41. But in China, it will only cost you $1.45. If you're traveling to Norway, though, it will cost you a whopping (pun intended) $6.88!
The Big Mac isn't a perfect way to measure exchange rates and purchasing power. After all, you can't trade them across international borders (eww!). But they have the advantage of being made the same way no matter where you go, an elusive quality in international markets.
