a-1. elasticity of supply between Y and Z is inelastic.

b. The statement is true.

Explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question. See the attached pdf file for the complete question.

The explanation of the answers is now provided as follows:

a. For each of the regions, use the midpoint method to identify whether the supply of this good is elastic or inelastic.

The midpoint formula is as follows:

Elasticity of supply = ((Q2 - Q1)/ (Q2 + Q1) /2) / ((P2 - P1) / (P1 + P2) /2) ……… (1)

Using equation (1), we have:

a-1. Between W and X

Q2 = 25

Q1 = 10

P2 = 20

P1 = 15

Substituting the values into equation (1), we have:

Elasticity of supply between W and X = ((25 - 10)/ (25 + 10) /2) / ((20 - 15) / (15 + 20) /2) = 3

Since 3 which is the calculated elasticity of supply between W and X is greater than 1, this implies that elasticity of supply between W and X is elastic.

a-2. Between Y and Z

Q2 = 90

Q1 = 80

P2 = 180

P1 = 90

Substituting the values into equation (1), we have:

Elasticity of supply between Y and Z = ((90 - 80)/ (90 + 80) /2) / ((180 - 90) / (180 + 90) /2) = 0.18

Since 0.18 which is the calculated elasticity of supply between Y and Z is less than 1, this implies that elasticity of supply between Y and Z is inelastic.

b. True or False: For high levels of quantity supplied where firms have reached near maximum capacity, supply becomes less elastic because firms may need to invest in additional capital in order to increase production further.

This statement is true.

This is because, from part a above, it can be observed that elasticity of supply between W and X when quantity is low is elastic but the elasticity of supply between Y and Z when the quantity is high is inelastic. Therefore, it is true that for high levels of quantity supplied where firms have reached near maximum capacity, supply becomes less elastic because firms may need to invest in additional capital in order to increase production further.
