Gradualism in dynamic agenda formation

We analyze a dynamic model of agenda formation in which players compete in each period to place their ideal policies on the agenda. In each period, with some probability, a decision maker takes an action from the agenda. We show that in any markov equilibrium of this game, players with extreme ideal policies will always compete to be in the agenda. On the other hand, there is a positive probability that in each round a more moderate policy will arise on the agenda. Therefore, agenda formation is a gradual process which evolves to include better policies for the decision maker but at a relatively slow pace.
