Strategic Behavior in Exhaustive Ballot Voting : What Can We Learn from the FIFA World Cup 2018 and 2022 Host Elections?

There are many allegations about whether FIFA world cup host countries were chosen honestly or not. We analyse the results of the FIFA Executive Committee voting and reconstruct the set of possible voting situations compatible with the results of each stage. In both elections, we identify strategic behaviour and then analyse the results for honest voting under all compatible voting situations. For the 2018 FIFA world cup election Russia is chosen for all profiles. For the 2022 elections the result depends on the preferences of the FIFA president Sepp Blatter who served as a tie-breaker. If Sepp Blatter prefers Qatar over South Korea and Japan, then Qatar would have been chosen for all profiles. Otherwise there are the possibility that South Korea or Japan would have been chosen as the 2022 host country. Another fact is that if we consider possible vote buying, then it is shown, that the bribery of at least 2 committee members would have been required to guarantee winning of Russia bid and at least 1 member for Qatar
