Agency theory suggests that between the principal (owner) and the agent (manager) have different interests, a conflict arises called an agency conflict. This separation of functions between owners and management has a negative impact, namely the flexibility of the management (manager) of the company to maximize profits. This condition occurs because of asymmetry information between management and other parties who do not have access to information about the company. It is therefore interesting to study management actions.
