Case studies

The Arbor City Community Foundation (ACCF) was a medium-sized endowment established in Illinois in the late 1970s through the hard work of several local families. The vision of the ACCF was to be a comprehensive center for philanthropy in the greater Arbor City region. ACCF had a fund balance (known collectively as “the fund”) of just under $240 million. The ACCF board of trustees had appointed a committee to oversee investment decisions relating to the foundation assets. The investment committee, under the guidance of the board, pursued an active risk-management policy for the fund. The committee members were primarily concerned with the volatility and distribution of portfolio returns. They relied on the value-at-risk (VaR) methodology as a measurement of the risk of both short- and mid-term investment losses. In its report for the investment committee, the ACCF risk analytics team recommended the daily VaR at 95% confidence as a measure for short-term risk and reported the corresponding numbers. It is now the task of the investment committee to interpret these figures. The case questions guide the executive students to a critical evaluation of both the reported VaR figures as well as of the VaR methodology.

The managing director of a steel plant faces the decision of how much of each raw material to order for the plant for the following month. Due to lower and upper bounds on the amounts of each raw material in a batch and varying amounts of electricity and time consumed for different raw materials, one can't simply use the cheapest raw material. A linear program and the solver optimization function of Excel will provide the optimal amounts that meet the constraints. Interestingly, the best mixture for a batch is not the best mixture for a monthly plan. Shadow prices indicate the value of relaxing constraints. The typical monthly model from a student will be nonlinear, although it can be written as a linear model. This case provides the basis for an introductory class on linear programming and linear versus nonlinear models.

A business analyst at Mead Corporation had just begun the process of estimating Mead's cost of capital for the fourth quarter of 1990. As part of her analysis, she hoped to explain why the cost of equity had increased and recommend whether the company should consider the increase a problem.

Quality Wireless has received customer complaints about long hold times at its call center. To address these complaints, it put into place certain process changes at its call center. After one month, the company will now decide whether improvement has taken place.

To develop an understanding of process capability and how an improvement can be statistically validated. To understand the “check” phase of the plan-do-check-act cycle of Deming, using basic statistical principles.

Since 1981, the U.S. federal government has operated a price support program to help sugar beet and sugar cane producers and processors. This complex program works through a combination of loans, import quotas, and duties. As a result, sugar prices in the United States are significantly higher than world prices. For example, in December 2001, U.S. consumers paid 22.9 cents per pound, while the world price was just 9 cents per pound. The General Accounting Office estimates that the total cost to consumers is $1.9 billion a year. Uses a simple demand-and-supply framework with real-world data to assess the economic and political consequences of the U.S. sugar program.

To illustrate welfare concepts such as consumer surplus, producer surplus, and dead-weight loss in a concrete, real-world market context.

In 2005, a wine snob in the critically acclaimed movie Sideways denounced merlot. Subsequently, sales of merlot, including sales for Terlato's Rutherford Hill merlot, declined significantly. Students are asked to evaluate three strategies---rebranding, cutting price, and launching television advertising---that Terlato is considering to reverse this decline. The case should be used with “Student Supplement: Terlato Wines International: Background Note on the U.S. Wine Market and Terlato Wines International,” Case #KEL359.

Students explore the challenge of managing a brand when external factors cause a decline in category demand. They also explore the role of pricing and advertising in managing a small, luxury brand.
