Below are sample questions representative of the exercises included on this worksheet and related 9.12 Supply, Demand, and Price Mechanisms skill assessments:

Problem 1Difficulty: Mastery

Use the graph of the bottled water market. A heat wave shifts demand right from D1 to D2, and a new bottling plant shifts supply right from S1 to S2. Why could the final market price rise, fall, or stay about the same while quantity definitely increases?

ABecause only demand shifts determine equilibrium quantity, while supply shifts determine only price.

BBecause both shifts raise quantity, but their opposite effects on price depend on which shift is larger.

CBecause simultaneous shifts always cancel each other out completely.

DBecause equilibrium price never changes when the good is a necessity.

Solution & Explanation:A rightward demand shift and a rightward supply shift both increase equilibrium quantity. Demand pushes price up, while supply pushes price down, so the final price depends on their relative size.

Problem 2Difficulty: Mastery

Use the graph showing a demand curve that becomes flatter after price-comparison apps spread among shoppers. Which explanation best fits the new curve?

AConsumers now have more information and can switch more easily, making demand more elastic.

BConsumers are forced to keep buying the product, making demand more inelastic.

CProducers found cheaper inputs, so supply became more elastic.

DThe market moved to a lower quantity on the same demand curve because price rose.

Solution & Explanation:Price-comparison tools make substitutes easier to find, so buyers respond more strongly to price differences and demand becomes more elastic.

Problem 3Difficulty: Mastery

A new bus line reduces demand for downtown parking, but garage capacity is fixed for the year. What is the most likely short-run result?

AParking prices fall sharply while the quantity rented changes less because supply is inelastic.

BParking prices rise sharply while quantity rented changes less because supply is inelastic.

CParking prices and quantity rented both stay constant because garages are fixed.

DParking prices fall only a little because demand shifts never matter when supply is fixed.

Solution & Explanation:When supply is fixed or very inelastic, a drop in demand mainly shows up as a lower price rather than a large quantity change.
