As a government official stated, "People who were already able to afford health care began to stop paying for it so they could get it for free." In this example, Hawaii's universal health care coverage caused:
A) crowding out.
B) expansion drift.
C) impure prevalence.
D) supplier-induced demand.
A) crowding out.
B) expansion drift.
C) impure prevalence.
