As you prepare for the Finance 4335 final exam you would do well to review key resources, including the Finance 4335 Course Overview, the Final exam formula sheet, and problem sets, class problems, and sample exams available on the course website.
By now, I assume that my Finance 4335 students
- Understand how to calculate and rank order risks based on expected utility;
- Understand how to apply the standard normal and binomial probability functions;
- Comprehend that one is risk averse/risk neutral/risk seeking if the risk premium is positive/zero/negative;
- are aware that the risk premium can be calculated in either of the following two ways: 1) by setting expected utility (E(U(W))) equal to the utility of the certainty equivalent of wealth (WCE ), solving for the WCE, and subtracting WCE from E(W), or 2) multiplying half of variance by the Arrow-Pratt Coefficient, evaluated at E(W) ();
- Understand that the risk premium () is positively related to the degree of risk aversion, as measured by the Arrow-Pratt Coefficient – thus, a decision-maker with logarithmic utility (U = ln W) is more risk averse than a decision-maker with power utility (U = Wn);
- Have learned that in a world where investors’ portfolios comprise combinations of the riskless asset and the market portfolio, only systematic is priced; i.e., ;
- Understand that riskless arbitrage ensures the formation of so-called “arbitrage-free” prices for financial derivatives such as futures/forward and options;
- Are aware that option pricing principles can value the option to default and determine the credit risk premium that investors demand from limited liability firms that issue debt.
