Answer:
1. The elasticity of demand for movie tickets must be INELASTIC.
2. Demand curves become LESS elastic in the long run. This means that the ticket price increase will likely be MORE profitable in the long run.
Explanation:
1. As demand is inelastic, the percentage of price increase will be greater than the decrease in the quantity of tickets demanded, and consequently profit will increase.
2. In the long term, demand becomes inelastic. Consequently, in the long term the percentage of the price increase will continue to be greater than the percentage of decrease in the quantity of tickets demanded.
