Question 1

An increase in price will cause a firm's total revenue to increase if demand is price elastic.

Accepted Answer

If demand is price elastic, an increase in price will lead to a proportionally larger decrease in quantity demanded, causing total revenue to decrease.

Question 2

Exhibit
The elasticity in the vicinity of five different points along a demand curve varies as follows:
 $\begin{array}{lccccc} 
\text { Point }& A & B & C & D & E \
\text { Elasticity} & 1.25 & 0.3 & 1.0 & 0.2 & 2.1
\end{array}$
-Refer to Exhibit. At which of these points would a price increase be accompanied by an increase in total revenue?

Accepted Answer

At points B and D, the elasticity is less than 1, indicating inelastic demand. In such cases, a price increase leads to an increase in total revenue.

Question 3

Exhibit
The elasticity in the vicinity of five different points along a demand curve varies as follows:
 $\begin{array}{lccccc} 
\text { Point }& A & B & C & D & E \
\text { Elasticity} & 1.25 & 0.3 & 1.0 & 0.2 & 2.1
\end{array}$
-Refer to Exhibit. At which of these points would sellers of a product want to increase price to increase their total revenue?

Accepted Answer

Sellers would want to increase the price at points where the demand is inelastic (elasticity < 1), as this would increase total revenue. Points B and D have elasticities of 0.3 and 0.2, respectively, indicating inelastic demand.

Question 6

Exhibit
The elasticity in the vicinity of five different points along a demand curve varies as follows:
 $\begin{array}{lccccc} 
\text { Point }& A & B & C & D & E \
\text { Elasticity} & 1.25 & 0.3 & 1.0 & 0.2 & 2.1
\end{array}$
-Refer to Exhibit. In the vicinity of which of these points would sellers find that their total revenue remained essentially unchanged as they changed their price?

Accepted Answer

At point C, elasticity is 1.0, which means that a 1% change in price will lead to a 1% change in total revenue.

Question 7

If an increase in prices increases total revenue for a product in the short run, in the long run, it will:

Accepted Answer

In the long run, demand may become more elastic as consumers find substitutes or change their consumption habits, leading to either a smaller increase or a decrease in total revenue.

Question 8

If a decrease in prices increases total revenue for a product in the short run, in the long run, it will:

Accepted Answer

The answer of If a decrease in prices increases total...

Question 9

The price of a new toy increases from $5 to $7 and the quantity demanded decreases from 12,000 to 6,000 per month as a result. Based on this information, the price elasticity of demand (in absolute terms) is estimated to be equal to:

Accepted Answer

The price elasticity of demand is calculated as the percentage change in quantity demanded divided by the percentage change in price. The percentage change in quantity demanded is ((6,000 - 12,000) / 12,000) * 100 = -50%. The percentage change in price is ((7 - 5) / 5) * 100 = 40%. The elasticity is |-50% / 40%| = 1.25, which is closer to 2.0 than 0.5, indicating relatively elastic demand.

Question 10

For a given change in demand:

Accepted Answer

In the long run, firms have more time to adjust their production levels, leading to a greater change in quantity compared to the short run.

Question 11

For a given change in demand:

Accepted Answer

In the long run, supply is more elastic, allowing quantity exchanged to adjust more. In the short run, prices adjust more due to less flexible supply.

Question 12

If the elasticity of demand for a good is greater than the government expected:

Accepted Answer

The answer of If the elasticity of demand for a...

Question 13

If the elasticity of supply for a good is greater than the government expected:

Accepted Answer

If the elasticity of supply is greater than expected, producers can more easily adjust their production in response to the tax, shifting more of the tax burden onto consumers.

Question 14

If the elasticity of supply for a good is greater than the government expected:

Accepted Answer

If the elasticity of supply is greater than expected, producers can more easily adjust their production, leading to a larger burden on consumers and potentially less tax revenue than anticipated.

Question 17

The income elasticities of Products A and B and their cross price elasticities with respect to Product C are as follows:??Income ElasticityCross Price ElasticityProduct A-2.1+2.5Product B+0.6-0.75From this information, one can conclude that:

Accepted Answer

Product A is inferior because its income elasticity is negative, indicating demand decreases as income increases. Product B is normal because its income elasticity is positive, indicating demand increases as income increases. Product A is a substitute for Product C because its cross price elasticity is positive, indicating demand for A increases as the price of C increases. Product B is a complement to Product C because its cross price elasticity is negative, indicating demand for B decreases as the price of C increases.

Question 18

If the income elasticity of demand for good A was 3.9 and the income elasticity of demand for B was 0.2:

Accepted Answer

Income elasticity of demand greater than zero indicates a normal good. Since both goods have positive income elasticity (3.9 for A and 0.2 for B), both are normal goods.
