摘要:在高能力经理的假定条件下,通过博弈方法将互惠偏好引入股东监督与经理管理防御的非完全信息博弈赛局中,研究经理互惠偏好对其管理防御水平的影响作用。研究结果表明:当股东对经理采取弱监督策略时,互惠型经理因互惠公平效用的增加而选择较低的管理防御水平;相反,当股东对经理采取强监督策略时,互惠型经理因较小的互惠公平效用而选择相对较高的管理防御水平。

Abstract: Utilizing the game method which introduces the reciprocal preference into the incomplete information game of shareholders supervise strategies with managers managerial entrenchment, this paper researches the influence of managers reciprocal preference to the level of managers managerial entrenchment, on the assumption that the managers is of high ability. The result shows that: the reciprocal type manager will select lower level of managerial entrenchment because of the increasing reciprocal fair utility when the shareholder adopts a weak supervision policy. On the contrary, the reciprocal type manager will select relatively higher level of managerial entrenchment because of the smaller reciprocal fair utility when the shareholder adopts a stronger supervision policy.
Key words: reciprocal preferences; shareholders supervision; managerial entrenchment; game

现有文献的解决方案大多以理性经济人为假设基础,认为经理管理防御动机是出于经理的自利性[1~ ],但是,Barkema发现经理对股东常常表现出非完全自利的非理性行为偏好[ ],即互惠偏好。互惠偏好理论关注行为人的心理偏好,而经理的这种心理偏好对企业经营决策有着极为重要的影响作用。管理防御是由经理内心动机决定的一种外在行为表现,内心深层次的想法主导经理行为,而互惠偏好同样也影响着经理内心深层次想法。……
