Eco 500: managerial economics: eco-500-16tw5-master 10

Problem 01-23 (Essay, Autogradable)
Two months ago, the owner of a car dealership (and a current football star) significantly changed his sales manager’s compensation plan. Under the old plan, the manager was paid a salary of $6,000 per month; under the new plan, she receives 2 percent of the sales price of each car sold. During the past two months, the number of cars sold increased by 40 percent, but the dealership’s margins (and profits) significantly declined. According to the sales manager, “Consumers are driving harder bargains and I have had to authorize significantly lower prices to remain competitive.” What advice should you give the owner of the dealership?

    Increase the percentage of the sales price the manager receives.
    Offer the manager a percentage of profits rather than sales.
    Pay the manager a fixed salary only.
Problem 01-21 (Essay, Autogradable)
Brazil points to its shrimp-farming industry as an example of how it can compete in world markets. One decade ago, Brazil exported a meager 400 tons of shrimp. Today, Brazil exports more than 58,000 tons of shrimp, with approximately one-third of that going to the United States. Brazilian shrimp farmers, however, potentially face a new challenge in the upcoming years. The Southern Shrimp Alliance – a U.S. organization representing shrimpers – filed a dumping complaint alleging that Brazil and five other shrimp-producing countries are selling shrimp below “fair market value.” The organization is calling for the United States to impose a 300 percent tariff on all shrimp entering the United States’ borders. Brazilian producers and the other five countries named in the complaint counter that they have a natural competitive advantage such as lower labor costs, availability of cheap land, and a more favorable climate, resulting in a higher yield per acre and permitting three harvests per year. In what many see as a bold move, the American Seafood Distributors Association – an organization representing supermarkets, shrimp processors, and restaurants – has supported Brazilian and other foreign producers, arguing that it is the Southern Shrimp Alliance that is engaging in unfair trade practices.

What type of rivalry exists between U.S.-based shrimp producers (represented by the Southern Shrimp Alliance) and foreign shrimp producers?

What type of rivalry exists between the members of the American Seafood Distributors Association and the U.S.-based shrimp producers?

Problem 01-15 (Algo)
Approximately 14 million Americans are addicted to drugs and alcohol. The federal government estimates that these addicts cost the U.S. economy $300 billion in medical expenses and lost productivity. Despite the enormous potential market, many biotech companies have shied away from funding research and development (R&D) initiatives to find a cure for drug and alcohol addiction. Your firm – Drug Abuse Sciences (DAS) – is a notable exception. It has spent $280 million to date working on a cure, but is now at a crossroads. It can either abandon its program or invest another $75 million today. Unfortunately, the firm’s opportunity cost of funds is 8 percent and it will take another five years before final approval from the Federal Drug Administration is achieved and the product is actually sold. Expected (year-end) profits from selling the drug are presented in the accompanying table.

What is the net present value of the project?

Instruction: Round your answer to the nearest penny (2 decimal places). Use a negative sign (-) where appropriate.


Should DAS continue with its plan to bring the drug to market, or should it abandon the project?

Problem 01-08 (Algo)
