Looking through the papers that are "in press" at Economics Letters today, I came across a paper by Anthony Landry, titled "Borders and Big Macs". (The link is to the working paper version.) Here's the abstract:
"I provide new estimates of border frictions for 14 countries using local, national, and international Big Mac prices. I ﬁnd that borders generally introduce only small price wedges, far smaller than those observed across New York City neighboring locations."This led me to wonder just how many academic papers have been written using the well-known "Big Mac Index" (BMI) that's published annually by The Economist magazine. I don't know the exact answer, but there are 39 listed on RePEc's IDEAS site.
That's a lot of burgers!
