Last week, The Economist published an alternative Big Mac Index. But this one didn't show prices of the famed sandwich as adjusted for exchange rates. This one showed the price of a Big Mac expressed in time spent to earn the price, based on average net wage in cities around the world.
The chart provides some interesting comparisons, but can raise many questions about costs, relative demand, etc. But it did remind me of an interesting annual report by the Federal Reserve Bank of Dallas. While it is now more than ten years old, and the data has certainly changed, it contained similar comparisons scattered on tables throughout the publication. What made it more interesting was the time/price equivalents were all within the U.S. at select times in through the 20th century.
I would think students in economics, personal finance or even Twentieth Century American History would find the information interesting and a prompt to discussion. What do you think? Please share.
