Description: In this study the author will review some correlations between the operating income per employee and some elements of company structure for the S&P 500 that are proxies for management control and supervision. An analysis yielded the following general observations: 1 companies in which the chairman and CEO roles are combined generate more income per employee than those in which the roles are separate 2 companies with a lead director and the chairman and CEO combined typically do better still 3 the more executive officers a company has, the higher operating income is generated per employee although this decreases marginally and 4 companies tend to gravitate toward a structure with 10 executive officers and 10 directors this is a fixed point of an iterative decision function.
