Suppose you are a risk-neutral manager attempting to hire a new sales manager. All of
the workers in the market have the same ability to manage and sell, but they differ with
respect to the wage at which they are willing to work for your company. The market for
sales managers is composed of three types of individuals: 85 percent are willing to
work for $75,000 and 15 percent are willing to work for $85,000. The first interviewee
is only willing to work for $85,000. If the human resource director spends five hours
interviewing each candidate and the opportunity cost of this director’s time is $500, then
the director should:
A. search again since the expected benefit of an additional search exceeds the cost.
B. stop searching since the expected benefit of an additional search is less than the cost.
C. search again since the expected benefit of an additional search is less than the cost.
D. stop searching since the expected benefit of an additional search exceeds the cost.
The rate at which a consumer is willing to substitute one good for another, while still
maintaining a given level of satisfaction, is called the
A. market rate of substitution.
B. average rate of substitution.
C. marginal rate of substitution.
D. budget constraint.
The market demand in a Bertrand duopoly is P = 10 – 3Q, and the marginal costs are $1.
Fixed costs are zero for both firms. Based on this information we can conclude that:
