| The paper finds current research mainly focuses on the study of the single incentives mode of managerial effort, based on the survey of the managerial incentives theory. Although managerial performance is the basic incentives rule, managerial effort is many aspect. In addition, managerial work can't narrate reasonable owing to managerial action impacting on output imperfectly and existing incomplete contracts, and moreover people's demand are many aspect, that illuminate managerial incentives can't rely on the single mode. This dissertation mainly studies some important issues of managerial combined incentives mode based on managerial effort and ability. So the paper studies the managerial combined incentives mode based on performance valuations, Needs levels, Career concerns.The paper studies the character of combined incentives mode on base of performance valuations, which includes perfect subjective valuation and imperfect subjective valuation. The results indicate that the owners are inclined to not sign up the subject incentive contract if the discount of the owner's expect payment is high enough, or the warp of the corporation performance valuation is low enough. Otherwise, the result is reverse. Analyzing the condition of the combined incentive contract coming into existence under the imperfect subjective valuation., the paper draws the conclusion: the variance of corporation subjective performance valuation is the lower, then the owner pays the more subjective incentive payment but the less objective incentive payment. In this combined incentives mode, the owner's and the manager's expected payments are increased on the condition of Pareto.Secondly, the paper studies the combined incentives mode based on the needs level, including the characters that immaterial incentives affect on the owner and manager net income change and relate with fixed payment of material incentives, incentives intensity, managerial risk- averse. The results indicate that immaterial incentives can improve the owner and manager net income. Further more, the value of managerial immaterial incentives are more different from the cost of the owner payment if managerial material incentives intensity or fixed material incentives or managerial risk- averse are more on condition that managerial material incentives are regarded as exterior variable. The examples indicate the results.Thirdly, the paper studies the two-period and multi-period combined incentives... |
