Managerial compensation, and their year to year change in wealth, varies significantly with the excess return on their firms stock. The positive correlation is primarily driven by the fact that managers hold stocks and options in their own firms. A large body of nonstructural empirical work has investigated how well managerial compensation can be rationalized by moral hazard.
As the dominant paradigm for explaining executive compensation, the theory of moral hazard postulates that risk averse managers are paid compensation that fluctuates with signals shareholders observe about decisions their managers make, notably excess returns of the firm, in order to align the incentives of the managers when their non pecuniary goals differ from maximizing shareholder wealth and the actions and decision of management are not monitored by shareholders. A growing number of papers on structural estimation have sort to quantify the economic significance of moral hazard in the labor market.
