Suppose That the Labor Market for High School Chemistry Teachers

Suppose that the labor market for high school chemistry teachers is initially in equilibrium. Chemistry teachers use laboratory chemicals as an important part of their jobs. New environmental regulations ban the use of many chemicals, which means that fewer laboratory chemicals are available for high school chemistry teachers to use in their jobs. What happens to the equilibrium wage and quantity of high school chemistry teachers?

A) Both the equilibrium wage and quantity increase.
B) Both the equilibrium wage and quantity decrease.
C) The equilibrium wage increases, and the equilibrium quantity decreases.
D) The equilibrium wage decreases, and the equilibrium quantity increases.
