I have two remarks on your graph. Although it is clearly better than the original one:

– I find the “2017 ’18” label confusing, as it is written with 2017 left to ’18, but is displayed above an arrow that goes in the other direction. I took me a while to understand that the tip of the arrow is ’18, and not 2017 as written above. I needed the note about Turkey on the right to figure out how to read them.

– I would have displayed a few more vertical lines to the graph. It is a bit hard to guess where are the ~five countries at the top as they are far from the axis labels, and I think it wouldn't saturate the graph to plot them.

Thank you very much anyway for all your impressive work on this blog.

The theory of the Big Mac index is that all Big Macs are the same, so if they're not the same, the theory fails.

But to complain that the index conflates things seems strange; that's the function of an index, and after all, you're often warning against data loss aversion.

derek: assuming all Big Macs are the same, how would you interpret the index?

reitrop: your 1st point is interesting. If I labeled the Turkey dots instead, the difficulty may not arise. on the 2nd point, it is a design choice :) I actually don't think half a burger or a tenth of a burger should be chewed over.
