Question 1

The management of Local Cinema has estimated the monthly demand for tickets to be ln Q = 22,328 − 0.41 ln P + 0.5 ln M − 0.33 ln A + 100 ln P_DVD,where Q = quantity of tickets demanded,P = price per ticket,M = income,A = advertising outlay,and P_DVD = price of a DVD rental.It is known that P = $5.50,M = $9,000,A = $900,and P_DVD = $3.00.Determine the own price elasticity of demand for movie tickets.

Accepted Answer

The own price elasticity of demand is calculated using the coefficient of the price variable in the demand equation, which is -0.41 in this case. This coefficient directly represents the own price elasticity of demand for movie tickets, indicating that a 1% increase in the price of movie tickets would lead to a 0.41% decrease in the quantity demanded.

Question 2

The demand for good X is given by ln Q_x^d = 120 − 0.9 ln P_x + 1.5 ln P_y − 0.7 ln M.Which of the following statements is correct?

Accepted Answer

The answer of The demand for good X is given...

Question 3

The short-run response of quantity demanded to a change in price is usually:

Accepted Answer

In the short-run, consumers may not have the ability to quickly adjust their consumption patterns in response to a change in price. Therefore, the short-run response of quantity demanded to a change in price is usually less than the long-run response. In the long-run, consumers have more time to adjust to price changes and find substitutes or alternatives.

Question 4

The demand for which of the following commodities is likely to be most price inelastic?

Accepted Answer

Food is a basic necessity and hence people are less likely to reduce their consumption even if the price increases. Therefore, the demand for food is likely to be most price inelastic.

Question 5

The demand for video recorders has been estimated to be linear and given by the demand relation Q_v = 145 − 3.2P_v + 7M − 0.95P_f − 39P_m,where Q_v is the quantity of video recorders,P_f denotes the price of video recorder film,P_m is the price of attending a movie,P_v is the price of video recorders,and M is income.Based on the estimated demand equation we can conclude:

Accepted Answer

The answer of The demand for video recorders has been...

Question 6

Accepted Answer

Question 7

The cross-price elasticity of demand between goods X and Y is −3.5.If the price of X decreases by 7 percent,the quantity demanded of Y will:

Accepted Answer

A negative cross-price elasticity implies that X and Y are complements, which means that as the price of X falls, the quantity demanded of Y increases. The magnitude of the cross-price elasticity (-3.5) means that a 1% decrease in the price of X leads to a 3.5% increase in the quantity demanded of Y. Therefore, a 7% decrease in the price of X would lead to a 24.5% increase in the quantity demanded of Y (7% x -3.5 = -24.5%). The answer is C because the question asks for the change in the quantity demanded of Y, which increases by 24.5%.

Question 8

If the demand function for a particular good is Q = 25 − 10P,then the price elasticity of demand (in absolute value)at a price of $1 is:

Accepted Answer

The answer of If the demand function for a particular...

Question 9

Suppose the demand for a product is Q_x^d = 12 − 3 ln P_x. Then demand for product x is:

Accepted Answer

The demand for product x can be considered elastic if the price elasticity of demand (PED) is greater than 1. It can be calculated by taking the percentage change in quantity demanded divided by the percentage change in price. However, since we do not have information on the specific values of P or Q, we cannot calculate PED exactly. But we do know that the demand equation includes a natural logarithm of P, which implies a decreasing marginal utility of income, suggesting the potential for elasticity. Additionally, the coefficient on the natural logarithm of P is negative, indicating an inverse relationship between P and Q. Therefore, we can conclude that the demand for product x is elastic.

Question 10

The management of Local Cinema has estimated the monthly demand for tickets to be ln Q = 22,328 − 0.41 ln P + 0.5 ln M − 0.33 ln A + 100 ln P_DVD,where Q = quantity of tickets demanded,P = price per ticket,M = income,A = advertising outlay,and P_DVD = price of a DVD rental.It is known that P = $5.50,M = $9,000,A = $900,and P_vcr = $3.00.Based on the information given,which of the following statements is false?

Accepted Answer

The given information only provides the price of a DVD rental, but does not provide any information about the price of movies. Therefore, it cannot be determined whether movies and DVD rentals are complements or substitutes.

Question 11

Each week Bill buys exactly 7 bottles of cola regardless of its price.Bill's own price elasticity of demand for cola IN ABSOLUTE VALUE is:

Accepted Answer

Bill's demand for cola is perfectly inelastic since his purchase quantity does not change regardless of the price. This is characterized by a price elasticity of demand of zero.

Question 12

The price elasticity of demand is −2.0 for a certain firm's product.If the firm raises price,the firm manager can expect total revenue to:

Accepted Answer

A price elasticity of demand of -2.0 means that for every 1% increase in price, quantity demanded will decrease by 2%. This implies that the demand for the product is fairly elastic. Therefore, if the firm raises its price, it can expect total revenue to decrease as the decrease in quantity demanded will more than offset the increase in price.

Question 13

The cross-price elasticity of demand for books and magazines is −2.0.If the price of magazines decreases by 10 percent,the quantity demanded of books will:

Accepted Answer

The cross-price elasticity of demand is negative, meaning books and magazines are substitute goods. When the price of magazines decreases by 10 percent, the demand for magazines will increase while the demand for books will decrease. The magnitude of the cross-price elasticity of demand implies that a 10 percent decrease in the price of magazines will lead to a 20 percent increase in the quantity demanded of books (-2.0 x 10 percent = -20 percent). Therefore, the quantity demanded of books will rise by 20 percent.

Question 14

When the price of sugar was "low," U.S.consumers spent a total of $3 billion annually on sugar consumption.When the price doubled,consumer expenditures increased to $5 billion annually.This data indicates that:

Accepted Answer

The fact that an increase in price led to only a relatively small decrease in quantity demanded (from $3 billion to $5 billion) suggests that demand for sugar is relatively inelastic. If demand was very responsive to price changes, a doubling of the price would have led to a much larger decline in consumer expenditures. B and D are incorrect because the data does not give us any information about the slope of the demand curve. C is incorrect because the data shows an increase in consumer expenditures, but we cannot assume that this means an increase in quantity demanded without more information about the exact relationship between price and quantity.

Question 15

When the price of sugar was "low," U.S.consumers spent a total of $3 billion annually on sugar consumption.When the price doubled,consumer expenditures remained at $3 billion annually.This data indicates that:

Question 18

The elasticity of demand for gasoline has been estimated to be 2.0,and the standard error is 1.0.The upper and lower bounds on the 95 percent confidence interval for the elasticity of demand for gasoline are:

Accepted Answer

The 95% confidence interval is calculated using the formula: estimate ± (critical value * standard error). For a 95% confidence level, the critical value is approximately 1.96. Therefore, the confidence interval for the elasticity of demand for gasoline would be 2.0 ± (1.96 * 1.0), which equals 0.04 to 3.96, not matching any of the provided options.

Question 20

The cross-price elasticity of demand for textbooks and copies of old exams is −3.5.If the price of copies of old exams increases by 10 percent,the quantity demanded of textbooks will:

Accepted Answer

The cross-price elasticity of demand is negative, indicating an inverse relationship between the demand for textbooks and the price of copies of old exams. The magnitude of -3.5 suggests that for every 1% increase in the price of copies of old exams, the quantity demanded of textbooks will fall by 3.5%. Therefore, a 10% increase in the price of copies of old exams will lead to a 35% decrease in the quantity demanded of textbooks, as per the formula: % change in quantity demanded of textbooks = (cross-price elasticity) x (% change in price of copies of old exams) = (-3.5) x (10) = -35.
