Scenario 1-1
Suppose a cell phone manufacturer currently sells 20,000 cell phones per week and
makes a profit of $5,000 per week. A manager at the plant observes, “Although the last
3,000 cell phones we produced and sold increased our revenue by $6,000 and our costs
by $6,700, we are still making an overall profit of $5,000 per week so I think we’re on
the right track. We are producing the optimal number of cell phones.”
Using marginal analysis terminology, what is another economic term for the
incremental cost of producing the last 3,000 cell phones?
A) marginal cost
B) operating cost
C) explicit cost
D) Any of the above terms are correct.
Which of the following is not a reason why the wages of workers and the prices of
inputs rise more slowly than the prices of final goods and services?
A) Contracts make prices and wages ‘sticky.”
B) Firms are often slow to adjust wages.
C) Menu costs make some prices sticky.
D) Unions are successful in pushing up wages.
