Information Rent and Hierarchies of Employee´s Income in Corporate

It is universal phenomena that the higher is the position of employee, the higher is employee\´s income. The common proposition of those dominant theories such as "ability perspective", "bribe perspective" and "tournament perspective", that explain the phenomena is that employee\´s marginal production equal employee\´s income. This paper argues that the information of labor input and labor\´s marginal product is asymmetry among hierarchies of corporate. The higher position\´s employees can secretly reduce their labor input, undervalue marginal production of these lower position\´s employees, and acquire more added income, namely information rent, which is another satisfactory explaining of hierarchies of employee\´s income in corporate.
