The "ratchet principle" and performance incentilves

The use of current performance as a partial basis for setting future targets is an almost universal feature of economic planning. This "ratchet principle," as it is sometimes called, creates a dynamic incentive problem for the enterprise. Higher rewards from better current performance must be weighed against the future assignment of more ambitious targets. In this paper I formulate the problem of the enterprise as a multiperiod stochastic optimization model incorporating an explicit feedback mechanism for target setting. I show that an optimal solution is easily characterized, and that the incentive effects of the ratchet principle can be fully analyzed in simple economic terms.
