Interest groups are introduced in a spatial model of electoral competition between two political parties. We show that, by coordinating voting behavior,these interest groups increase the winning set, which is defined as the set of policy platforms for the challenger that will defeat the...

We generalize the traditional concept of single-peaked preference domains in two ways. First, we introduce the concept of a multiple single-peaked domain, where the set of alternatives is equipped with several underlying orderings with respect to which a preference can be single-peaked, and we...

n this work factor analysis is used to obtain a two-dimensional map of ideological preferences of the Russian elec-torate. It is shown that Moscow is the most polarized region with respect to ideological preferences. A spatial model of voting, based on the assumption that the voter’s utility...

We develop several results related to equilibrium in sophisticated voting under an amendment agenda procedure and supermajoritarian voting rules. Contrary to the simple majority case, we demonstrate that attainable equilibria are a function of the location of the status quo ex ante as well as...
