According to the Economist and their handy chart, you can’t get a Big Mac cheaper anywhere else. While in the U.S., a Big Mac costs around $3.71, one could get the same sized burger here at a McDonalds for just $2.18. Which could mean, as the Economist argues, that “[the yuan] is undervalued by about 40%.” Of course, the simplicity of the Big Mac index doesn’t take into account things like the fact that you could get a jianbing for 2.50 yuan instead, which is five times cheaper than the famous McD burger. I’d bet that influences the prices of fast food greatly. Honestly, does the index work for any country where over half their residents are still operating under third-world conditions?
