I.

A decrease in quantity demanded

II.

A decrease in demand

III.

An increase in demand

IV.

Homework Answers

Answer #1

1) Supply curve shifts because determinant of supply has changed. Quantity supplied cause movement along the supply curve which occurs due to change in price.

Option B is correct.

2) If marginal product is equal to average product, marginal product is decreasing.

Option C is correct.

3) Extra revenue generated from selling additional unit is marginal revenue.

Option B is correct

4) Option A is incorrect because its demand curve is downward sloping.

Monopoly is the firm which is the industry which makes option B correct

Option C is incorrect because there is only one firm in the indutry.

Option D is incorrect becuase low cross elasticities is related with complement good while there is no substitute available of good produced by monopoly.

5) A good is normal good if increase in buyer's income increase demand. Option C is correct.
