Incentives in Mixed-Member Electoral Systems

Abstract

Mixed-member systems have been characterized as encouraging politicians to balance the activities that enhance their personal reputations and those of their parties. Another literature challenges that legislators from one tier are not likely to behave differently from those of the other. After summarizing this debate, data from Venezuela are used to look for evidence supporting either side in a series of behaviors that span the entire legislative process—from bill initiation to committee consideration to final vote. The author concludes that the “best of both worlds” versus “contamination” debate has led to a focus on mixed-member institutions, to the exclusion of other incentive structures confronting legislators and that we need to engage in more careful theorizing about when and where they should expect the electoral tier to have an impact on legislator behavior.
