The Principal-Agent Problem Principals (stockholders)- want maximum company profit and stock price. Agents (managers) –may want the power, prestige and pay that often accompany control over a large enterprise, independent of profitability and stock price. For example, executives may build expensive office buildings, enjoy the use of corporate jets, pay too much to acquire other corporations. Differences in objectives (profits vs. salary) –so a conflict of interest may exist between the principal and the agent Public Sector Government’s role Providing legal structure: government establishes rules of the game that control relationships among businesses, resource suppliers and consumers. Optimum amount of regulation is established so that the MB and MC are equal Maintaining competition: in most markets, efficient production can be best attained with a high degree of competition.
