Template-Type: ReDIF-Paper 1.0 Title: Partisan Voting Under Uncertainty Author-Name: Lily Ling Yang Author-Email: lily.yang@uni-mannheim.de Classification-JEL: C72, D72, D81 Keywords: Common values, Elections, Information aggregation, Knightian uncertainty, Partisan voting Abstract: We consider a common-value voting model in which voters are uncertain about the precision of the information they receive. With incomplete preference, party supporters adopt their own party as their status quo and vote for it whenever it is justi…able under some belief. Uncertainty is ampli…ed by strategic consideration. As a result, voting becomes fully partisan and party supporters stick to their own party in large elections, even though all voters share the same preference. Additionally, voting is more partisan when voting is compulsory or when the population of party supporters is sufficiently large.
