Advantageous candidates and the selection process

I study elections where some candidates have an advantage unrelated to their competence. Although this advantage is negligible in general elections, it is significant during candidate selection by parties. Further, the built-in advantages of some candidates may be a measure of the political system’s inefficiency. The selection of candidates by a party is a crucial institution for this inefficiency to exist. Theoretically, I show that the preciseness of the party’s estimation of candidates’ chances of winning a general election has a non-monotonic effect.
