摘要
本文主要基于基德兰德和普雷斯科特及其他人的后续研究,着重讨论了承诺对经济政策有效性的影响。本文指出,承诺通过稳定预期等有助于经济政策的有效制定和执行;但给定环境的不确定和参与人的有限理性,承诺是不完全的,这就出现了经济政策的时间不一致问题。但不完全承诺对经济本身的影响有利有弊,有效承诺应该包含一定的灵活性。保障有效承诺需要相应的制度安排,比如授权、声誉及宪政等。
Based on Kydland and Prescott and others' research, this paper has focus on discussing that commitment has influence on the efficiency of economic policies. According to these ideas, commitment may help to efficiently constitute and perform economic policies through stabilizing expectation, but commitment is incomplete under environment's uncertainty and agent's bounded rationality, the time-inconsistency of economic policies will occur. Incomplete commitment may be good or bad for economy, efficient commitment must include flexibility. Some institutions are designed for safeguarding efficient commitment, for instance, authorizing, reputation, and constitution.$$$$
