A Model of Endogenous Party Membership and Platforms with Opportunistic Politicians
Kwang-ho Kim (Hanyang University)Year 2018Vol. 34No. 1
We model endogenous party membership choice and party platform formation whenparty activists differ not only in their policy preference but also in the intensity with whichthey pursue policy issues vis-a-vis the spoils from electoral victories. We provide existenceresults for equilibria in which (i) party activists choose their party affiliation with correctanticipation of the choices by others and (ii) the resulting party platforms are consistent withthe affiliation choice. This model offers an explanation for the overlaps in ideology betweenpolitical parties. It also provides insights into the internal composition of political partieswith different sizes.
