Democratic Policy Making with Real-Time Agenda Setting: Part 1

We examine democratic policy-making in a simple institution with real-time agenda setting. Individuals are recognized sequentially. Once recognized, an individual makes a proposal, which is immediately put to a vote. If a proposal passes, it supercedes all previously passed proposals. The policy that emerges from this process is implemented. For some familiar classes of policy spaces with rich distributional politics, we show that the last proposer is effectively a dictator under a variety of natural conditions. Most notably, this occurs whenever a sufficient number of individuals have opportunities to make proposals. Thus, under reasonably general assumptions, control of the final proposal with real-time agenda setting confers as much power as control of the entire agenda.
