RT Journal Article T1 Ideological versus Downsian political competition A1 Ortuño, Ignacio AB We analyze a one-dimensional model of spatial political competitionwith two parties and uncertainty on the distribution of voters’ types. We assumethat parties are formed by regular members and professional politicians;members care about the policy enacted, while professional politicians, on thecontrary, care only about winning the election. We consider two possibilities:that members choose the political platforms and that professional politiciansare the ones who choose such platforms. The expected utility for party membersis analyzed under these two cases. We find that when professional politicianshave no informational advantage, it is on the interest of both partiesto let professional politicians choose the platforms. Only in the case in whichprofessional politicians have much better information than the members of theparty about voters is it possible that party members obtain a greater expectedutility choosing the platforms themselves rather than letting the professionalpoliticians choose.
