Besides voter strategy, cycles affect procedural structure, how the process of social choice is organized before anyone gets to vote. One way is by making outcomes highly dependent on the fine details of legislative agendas. That can happen in quite a variety of ways – in the sequence and interdependence of pairwise votes, in the membership of feasible sets, and in the joining or dividing of “questions,” or agenda items. Sometimes cycles also turn the apparent asset of veto (or concurrence) power – the power that ties together the parts of government in a separated-powers system – into a liability, a bad thing merely to possess. And cycles create the incentive to form political parties.
