Summary
For the last few years, in late December or early January, the Economist usually releases a chart with a title something like "which countries did the best".
Types of markets
Ranking
Above, there are multiple types of options. The first, type is like this:
Denmark [0% for 11th, 10% for 10th, 100% for 1st]
This means that the first 10 places will be scored, counting down 100% to 0%.
Ties resolve with the nominal value (8=, 8= => 80% for both)
A vs B
Another type is "A vs B" markets; these resolve by whether A will beat B. If A wins, 100%. If B wins, 0%. If they tie, then 50%. This is based on the ranking, and note that the Economist includes ties (in 2023, designated by a sequence of rank numbers such as "8=, 8=, 10=" which means there were two countries tied for 8th, to preserve logic, therefore 9th was skipped. If A appears in the list, and B doesn't A wins. If neither appears, then NA.
A vs B win margin
For these, we look at how many places ahead A is. If tied or behind or missing, score is 0%. If A is ahead by 1 place (for example, 1st vs 2nd place) then 10%. If by 10 or more places, score is 100%.
