Award: 5 out of 5.00 points Demand is (more elastic / less elastic) in the short run than in the long run (more elastic) because goods account for a larger percentage of the consumer's budget in the short run than in the long run. (less elastic) because goods account for a smaller percentage of the consumer's budget in the short run than in the long run. (more elastic) because consumers have less time to adapt to a price change in the short run than in the long run. (less elastic) because consumers have less time to adapt to a price change in the short run than in the long run. References Multiple Choice Difficulty: 02 Medium Learning Objective: 06-03
