考虑一个委员会，它面临着决定如何改变几个变量的大小的任务。它被认为是由多数决定的协议。决策机构可以是试图决定若干投资项目规模的董事会，也可以是决定在若干公益物之间分配预算的一组个人。只要变量可以想象地改变任何数量，设置就没有区别。如果变量的改变被提议并且改变没有得到多数票，则变量的“现有状态”保持不变。如果变量的任何可能变化都不能获得多数票，那么变量的“现有状态”就是一个“均衡”。"
Consider a committee that is faced with the task of deciding on how to change the magnitude of several variables. It is assumed that agreement is defined by majority rule. The decision-making body could be a board of directors attempting to decide on the magnitude of several investment projects, or a group of individuals deciding upon the allocation of a budget among several public goods. The setting makes no difference as long as the variables could conceivably be changed by any amount. If a change in the variables is proposed and the change does not receive a majority vote, then the "existing state" of the variables remains. If no possible change in the variables could receive a majority vote, then the "existing state" of the variables is an "equilibrium."
