Split Ticket Voting and Social Networks in New and Established Democracies: A Quasi-Experiment in the 1990 German Unification Elections

When deciding to cast a split ticket ballot, voters in established democracies can rely on their experience with democracy and long term party attachments to guide their voting behavior. However, voters in new democracies do not have these individual level sources of information and motivation, and may instead rely on information from their social networks. Using the 1990 Cross-National Election Project German Unification election study, I examine the information sources West and East Germans use when splitting their ballot. I find that political disagreement within a social network is much more influential in decisions to cast a split ticket ballot for East German voters, while individual-level traits, particularly party attachment, play a greater role for West German voters. These findings indicate that, in absence of competition between individual-level information sources, network characteristics may have a profound impact on political decision-making.
