I propose a businessman whose output cannot be measured very well earns p/r+log(e)+k, where p is the profit the company makes, r is his rank within the company (CEO is 1, CFO/CMO is 2, etc), e is the number of employees beneath him, and k is the base salary at that firm. The idea here is that upper management at certain companies effectively own the firm and distribute profit accordingly, while middle management usually advances in income by increasing empire. Edit: variable name.
