Legislature-Executive Trade off
Let us move a bit closer to the reality. In standard modes of policy optimization we assure that there is a single policy maker, who controls the setting of policy and agenda, we shall see that in opportunistic models, he manipulates the policy to maximize the probability of his success in coming elections. This approach, in fact ignores one of the hard realities of democratic system. The institutional structure to such that numerous political actors affect the choices will respect to policy and agenda. As a result under democracy, the final policy which emerges is a result of interplay of very many agents rather than a single policy maker.
