Answer:
Explanation:
Given:
Short-run price elasticity = - 0.85
Long-run price elasticity = - 3.2
Cross-price elasticity = - 0.26
Income elasticity = 0.75
a. If the theater raises movie ticket prices by 10 percent it means that percentage of price change is 10%.
[tex]Elasticity = \frac{Percentage change in Quantity demanded}{Percentage change in price} \\\\-0.85 = \frac{Percent change in Quantity demanded\\}{10} \\\\Percent change in Quantity demanded = -0.85*10\\ \\ = -8.5[/tex]
Thus, quantity demanded falls by 8.5 percent.
b. Short-run price elasticity is different from long-run elasticity due to the time horizon. When individuals have more time they can switch to cheaper alternatives. While, it takes time to adjust in the short-run as the time horizon is not much. So short-run elasticity is less elastic than in the long-run.
c.
In the long-run demand for movie tickets is very elastic. So as price rises in the long-run, quantity demanded falls by a greater proportion. This will cause total revenue to fall in the long-run.
d. Normal goods are goods which have a positive income elasticity. This means for normal goods demand increases as income increases. But in case of inferior goods, demand is inversely related to income. As income rises demand for inferior goods decreases.
Since in this case, income elasticity is 0.75 (positive) it can be concluded that movie tickets are normal goods.
e. Good X is the related good to movie tickets. As cross price elasticity is -0.26 it means that as price of movie tickets rises by 1 percent demand for good X will fall by 0.26 percent.
Thus, as demand for good X and price of movie tickets are inversely related to each other it can be said that they are complementary goods.
If the price of movie tickets are increased by 10%, quantity demanded would increase by 8.5%.
b. The short run elasticity of demand differs from the long run elasticity of demand because in the short run there is limited time to search for suitable suitable alternatives for movies.
c. If the price of movie tickets are increased revenue would decline because demand is elastic.
d. Movie tickets are a normal good. This is because its coefficient of elasticity is greater than zero.
e. If the price of movie tickets are increased, the demand for good X would decline. This is because the two goods are complements.
What is the price elasticity of demand?
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.
Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one.
What are normal and inferior goods?
Normal goods are goods that are goods whose demand increases when income increases and falls when income falls. Inferior goods are goods whose demand falls when income rises and increases when income falls.
