For example, proponents of agency theory argue that managers in management-controlled firms (contrasted with owner-controlled firm in which the founder or family still own a significant amount of stock) select less risky strategies with quick payoffs in order to keep their jobs. This view is supported by research revealing that manager-controlled firms (with weak boards) are more likely to go into debt to diversify into unrelated markets (thus quickly boosting sales and assets to justify higher salaries for themselves),thus resulting in poorer long-term performance than owner-controlled firm.
