Global Resources Case 20
Risk-Adjusted Discount Rates
Purpose: The case covers the process of adjusting the discount rate to account for the risk in a project.
It clearly demonstrates that the risk-adjusted discount rate approach can affect (and change) the ranking
of investments. It further brings an international dimension into the decision making process and
encourages the student to address the issue of whether international investments increase risk because
of uncertainty or decrease risk because of diversification. The concept of mutually exclusive
investments is also incorporated in the case.
Relation to Text: The case should follow Chapter 13.
Complexity: The case is moderately complex and should require one hour.
