Review some concepts like agency theory and insider trading. Provide examples of each. Solution Agency Theory: A theory explaining the relationship between principals, such as a shareholders, and agents, such as a company\'s executives. In this relationship the principal delegates or hires an agent to perform work. The theory attempts to deal with two specific problems: first, that the goals of the principal and agent are not in conflict (agency problem), and second, that the principal and agent reconcile different tolerances for risk Example: Investment Banks act as agents for their clients. Insider Trading: Insider trading is defined as a malpractice wherein trade of a company\'s securities is undertaken by people who by virtue of their work have access to the otherwise non public information which can be crucial for making investment decisions. Example: A high-level employee of a company overhears a meeting where the CFO is talking about how the company is going to be driven into bankruptcy as a result of severe financial problems. The employee knows that his friend owns shares of the company. The employee warns his friend that he needs to sell his shares right away. .
