Question 2

If the short-term own price elasticity for food is estimated to be −0.4,then long-term own price elasticity is expected to be:

Accepted Answer

In the long-term, consumers can adjust their consumption patterns and find substitutes for the food. Therefore, the long-term own price elasticity is expected to be more elastic (greater in absolute value) than the short-term own price elasticity. As the short-term own price elasticity is −0.4 (negative and less than one in absolute value), the long-term own price elasticity is expected to be more elastic (greater in absolute value), meaning that it is less than −0.4. Therefore, the best choice is C, less than −0.4.

Question 11

Suppose the demand function is given by Q_x^d = 10P_x^0.9 P_y^0.5 M^0.22 H.Then the cross-price elasticity between goods x and y is:

Accepted Answer

The cross-price elasticity between goods x and y is given by the exponent of P_y in the demand function, which is 0.5.

Question 12

If a price increase from $8 to $10 causes quantity demanded to fall from 500 to 400,what is the absolute value of the own price elasticity at a price of $10?

Accepted Answer

The formula for own price elasticity of demand is:
%=∆Q/∆P × P/Q

Using the given information,
∆P = $2 (an increase from $8 to $10)
∆Q = -100 (a decrease from 500 to 400)

%∆P = (∆P / P avg) × 100 = [(10-8)/((10+8)/2)] × 100 = (2/9) × 100 ≈ 22.22%

%∆Q = (∆Q / Q avg) × 100 = [-100/((500+400)/2)] × 100 = -25%

Own price elasticity at a price of $10 can be calculated as:
|E| = |(%∆Q / %∆P)| = |(-25/22.22)| ≈ 1.125

Rounding off to two decimal places, we get the answer as 1.25. Therefore, the answer is B.

Question 13

Suppose the equilibrium price in the market is $24 and the price elasticity of demand for the linear demand function at the market equilibrium is −1.5.Then we know that:

Accepted Answer

Marginal revenue (MR) can be calculated using the price elasticity of demand (PED) formula at the equilibrium point, where PED = -1.5 and P = $24. The formula relating PED, MR, and P is MR = P(1 + 1/PED). Substituting the given values, MR = $24(1 + 1/(-1.5)) = $24(1 - 2/3) = $24(1/3) = $8. This calculation shows that when demand is elastic (|PED| > 1), the marginal revenue is positive but less than the price.

Question 14

Suppose a regression with 51 observations returns a regression sum of squares of 56,000 and a total sum of squares of 250,000.The associated residual sum of squares is:

Accepted Answer

The residual sum of squares (RSS) can be calculated as the total sum of squares (TSS) minus the regression sum of squares (RSS), i.e., RSS = TSS - RSS. Here, it is 250,000 - 56,000 = 194,000.

a.A 5 percent reduction in the price of cereal.
b.A 4 percent increase in income.
c.A 20 percent reduction in cereal advertising.

Question 16

When the price of corn was "low," consumers in the United States spent a total of $8 billion annually on its consumption.When the price halved,consumer expenditures actually DECREASED to $6 billion annually.This indicates that:

Accepted Answer

This indicates that the demand for corn is inelastic, meaning that the change in price did not significantly impact the quantity demanded by consumers.

Question 17

Accepted Answer

Bill's own price elasticity of demand for hot dogs is zero because he always buys 10 hot dogs regardless of their price. This indicates that his demand is perfectly inelastic.

Question 18

Question 19

If the demand function for a particular good is Q = 20 − 8P,then demand at a price of $1 is:

Accepted Answer

To determine the elasticity at a price of $1, we need to calculate the price elasticity of demand (PED) at that price point.

PED = (% Change in Quantity Demanded / % Change in Price)

At a price of $1, the demand function becomes Q = 20 - 8(1) = 12.

If the price increases by 1%, the quantity demanded will decrease by 8%.

PED = (-8%/1%) = -8

Since the absolute value of the elasticity is greater than 1, demand is considered inelastic. Therefore, the answer is C.

Question 20

If the demand function for a particular good is Q = 50 − 4P,then demand at a price of $10 is:

Accepted Answer

The elasticity of demand can be calculated using the formula: E = (dQ/dP) * (P/Q). At P = $10, Q = 50 - 4(10) = 10. The derivative dQ/dP = -4. So, E = (-4) * (10/10) = -4, which is less than -1, indicating elastic demand.
