Scenario 18-8 Suppose the following events occur in the market for university economics professors. Event 1: A recession in the U.S. economy lowers the opportunity cost of going to graduate school in economics to become a university economics professor.

As a result of these two events, holding all else constant, the equilibrium wages of university economics professors will


A) increase.
B) decrease.
C) not change.
D) It is not possible to determine what will happen to the equilibrium wage.
