Majority voting solution concepts and redistributive taxation

Abstract.

Strong assumptions are usually needed to guarantee the existence of a Condorcet winner in majority voting games. The theoretical literature has developed various solution concepts to accommodate the general absence of Condorcet winner, but very little is known on their economic implications. In this paper, I select three such concepts (the uncovered set, the bipartisan set and the minmax set), defined as game-theoretical solution concepts applied to a Downsian electoral competition game. These concepts are then computed by means of simulations in a simple model of purely redistributive taxation, where factor supply varies with net factor rewards. All three concepts give rather sharp predictions and are not too sensitive to small variations of the preference profiles.
