Voting on the flag of the Weimar Republic

We describe and analyze the voting process leading to the compromise achieved in the Weimar Flag Controversy. We also offer a simple theoretical model that attempts to capture the main forces at work. These forces are: (1) the addition of a compromise alternative that is located between the main ideological positions on the left and on the right; (2) the interdependence of preferences that makes the compromise salient; and (3) a voting process that gradually reveals and aggregates information. Finally, we compare the theoretical insights with the observed outcome.
