Question

Stricter environmental regulations and increased demand for energy have caused an increase in the demand for relatively clean natural gas. In the last several years, improved extraction technologies and new discoveries have increased the availability of natural gas. What has been the net effect on price and quantity for natural gas?a. Quantity sold and price both fell with certainty. b. Quantity sold fell and the effect on price is ambiguous. c. Quantity sold and price both rose with certainty. d. Quantity sold rose while the effect on price is ambiguous.

Answer 1

Answer:

D) Quantity sold rose while the effect on price is ambiguous.

Explanation:

Two separate things happened here;

• Change in consumer habits have shifted the the demand curve to the right, increasing the quantity demanded at every price level.
• Better technology and lower costs have also shifted the supply curve to the right, increasing the quantity supplied at every price level.

One thing is certain, the quantity demanded and supplied increased, so the total quantity sold definitely increased. The price issue is not certain because you would need additional information about which shift was larger, the shift of the supply curve or the demand curve.
