Abstract:

In many political jurisdictions, electoral districts are served by multiple representatives. In
these multi-member district (MMD) contexts, elections pit incumbent legislators not only against challengers from rival parties, but also other incumbents in the same district, including co-partisan incumbents. We develop a formal theory of legislative representation in MMD systems, in which legislators trade o the pursuit of collective goals versus cultivating personal reputations. We unearth contexts in which MMD electoral systems can more eectively balance the interests of voters and parties as competing principals, relative to single-member districts (SMD). Our framework allows us to unify and re-examine a raft of existing theoretical and empirical claims about the consequences of proportional representation, and further derive new and testable empirical hypothesis about legislative cohesion across dierent MMD electoral rules.
