This article examines how authoritarian regimes use legislative institutions to coopt rival elites and induce policy cooperation. Theories of cooptation under authoritarianism emphasize two mechanisms: economic rents and policy concessions. Despite the persistence of these mechanisms in the literature, evidence of their effect on policy outcomes remains limited. In this paper, we develop a theory of legislative cooptation, or the intentional exchange of economic rents and policy concessions to legislators in exchange for policy cooperation. We test our theory using a novel dataset of 150,000 roll-call votes from the Kuwait National Assembly that spans the entirety of Kuwait’s legislative history. We leverage the regime’s participation in the legislature to establish a measure of legislative cooperation and use this measure to estimate the efficacy of mechanisms of cooptation in inducing conformity with its policy agenda. Both mechanisms effectively elicit cooperation: but they have different strategic and normative implications for our understanding of how representation emerges in non-democratic contexts.
