Answer #1

No. It is not true.

For a necessary good, the income elasticity is positive. So, a consumer will buy more of the necessary goods as income increases.

For an inferior good, the income elasticity is negative. So, a consumer will buy less of an inferior good as income increases.

For a luxury good, the income elasticity is greater than 1. So, a consumer will buy more of a luxury good as income increases.

(So the price of Y is normalized to be 1). The income of this consumer is 100. (a) (10pts) Derive the demand function of x for this consumer. Make sure that at every price of x, the consumer always has enough income to buy the amount of x as indicated...
