Suppose voters are uniformly distributed along a continuum between 0 and 1. There are two candidates. Voters will vote for the candidate who locates closes to them. Candidates only care about receiving more votes than the other candidate (and prefer a tie to losing).What is the rationalizable set of locations for each candidate?

Answer #1

The rationalizable location will be 1st quarlitle and 3rd quartile --

For, uniform distribution

Consider, X -Location of voter

Then X ~ U(0,1)

i.e, f(x) = 1 , 0<x <1

So, rth quartile is ---

thus, m=r/4

now, put r =1 for 1st quartile and r=3 for 3rd quartile

So, 1st quartile = 0.25

3rd quartile = 0.75

So, candidates locations are at 0.25 and 0.75 along a continuum

    Political Competition Each of 2 political candidates chooses a policy position x e l0, 1: Voters (there is a continuum of them) are uniformly distributed on [0,1]; each votes for whichever candidate chooses a position closest to him.

Ten percent of the votes are at each location on the spectrum. Each candidate wants to maximize her share of the votes by choosing her position on the spectrum; voters vote for the candidate closest to their position on the spectrum, and if there is a tie in distance they split their...

In particular, let q R L be the difference in quality between candidate R and candidate L. There is no cost of voting and the utility is equal to one if the higher quality candidate wins and zero otherwise The winner is determined by majority rule. When q is observable, each voter votes for the higher quality...

    Elections between Hillary and Trump. There are only three voters and all of them strictly prefer Hilary to Trump. We assume that voters' utility only depends on the candidate that wins the election. In the first round, all voters vote simultaneously. If a candidate is voted by all the three voters, this candidate is elected. If none of the two candidates receives all the votes, then a second round takes place. All voters vote again simultaneously, but the winner is...
