Abstract:

In response to the impact of Novel coronavirus pneumonia, China State Shipbuilding Corporation Limited is implementing Cost Engineering Project regarded as a life project concerning the future destiny of the group. China State Shipbuilding Corporation Limited is trying its best to reduce the cost and expenses of shipbuilding. Our universtiy has a long history with the group and used to belong to it. Being separated, both sides still have closely strategic cooperation. Therefore, we are deeply involved in this project lasted for one year. During the course of cooperation, it seems that there was a serious asymmetry about shipbuilding cost information between group and shipyards.Headquarters of state-owned enterprise (principal) authorizes production unit (agent) to proceed cost control. It is reasonable to anticipate that the performance of cost control in previous period might become the reference of next budget cost. Agent with high ability is inclined to make low effort so as to conceal real efficiency, high cost followed in current period, which is ratchet effect.The impact of two kinds of incentive mechanism is examined and compared, i.e., saving sharing of cost reduction (realized number of cost is lower than budget) and target sharing (share after completion of cost reduction target), on the ratchet effect. In a principal-agent relationship with dynamic and adverse selection, the principal commits a long-term specific incentive mechanism (with fixed structure and variable parameters), but doesn't commit intertemporal incentive scheme (with fixed structure and fixed parameters). Then the ratchet effect occurs but varies with the different incentive mechanism. Game theory is employed to explore the analysis framework of principal-agent based on the theory of information asymmetry. This study shows target sharing incentive mechanism (TIM) could weaken ratchet effect efficiently compared with saving sharing incentive mechanism (SIM) in a perfect Bayesian equilibrium.

Key words: cost control, ratchet effect, sharing saving incentive mechanism(SIM), target incentive mechanism(TIM)
