Solutions to Essay Questions - Midterm Exam Econ 423 1 51) What is the expected return on a bond if the return is 9% two-thirds of the time and 3% one-third of the time?

Solutions to Essay Questions - Midterm Exam Econ 423 2 According to the efficient markets hypothesis, we know that an efficient market fully reflects all available information, and that current prices in a financial market are set so that the optimal forecast of a security's return is equal to the security's actual return in equilibrium. Applying this to the efficient market described in the problem, we know that if the market is efficient and the bankruptcy filing is fully anticipated, then the price of a security issued by the firm should already account for the anticipated bankruptcy before the official announcement.
