b. Laws prevent stores from responding to excess demand in time to prevent a shortage.

c. Manufacturers charge extremely high prices for the goods that stores are unwilling to pay.

d. Demand increases so quickly and unexpectedly that time is needed for the quantity supplied and
price to increase to reach a new equilibrium point.
