Music compact discs are normal goods. What will happen to the equilibrium price and quantity of music compact discs if musicians accept lower royalties, compact disc players become cheaper, more firms start producing music compact discs, and music lovers experience an increase in income? a. Price will fall, and the effect on quantity is ambiguous. b. Price will rise, and the effect on quantity is ambiguous. c. Quantity will fall, and the effect on price is ambiguous. d. Quantity will rise, and the effect on price is ambiguous.

The correct answer is option d.

Explanation:

Music compact discs are normal goods. This means that they have a positive income elasticity.

If musicians lower their royalties the cost of producing CDs will get reduced and producers will have more profit. The producers will be able to produce more compact discs at the same cost. This will cause the supply of compact discs to increase. As a result, the supply curve will move to the right.

Compact discs player is a complementary good for compact discs. A fall in the price of the complement will increase the demand for discs. At the same, an increase in income of music lovers will contribute to increasing the demand for discs.

As a result, the demand curve will shift to the right. This rightward shift in both the demand as well as the supply curve will cause the equilibrium quantity to increase. The change in price will depend upon the extent of change in demand and supply.
