Suppose that a consumer consumes only two goods, coconuts and bananas. Suppose that the price of bananas increases.

A) Explain the direction of the income effect and substitution effect for both goods if both goods are normal goods.

B) What we say about the total change in the consumption of bananas if a banana is an inferior good?

Homework Answers

Answer #1

a)

Fall in price of Bananas can be analysed through income and substitution effects. Income effect would be positive here. In other words, rise in income shall lead to rise in demand for Bananas.

Substitute effect shall be negative. Both Income and substitution effects shall move in same direction. thus demand for Bananas shall rise and demand for coconuts would fall.

b)

Inferior good means demand for bananas is inversely related to income of consumer. Rise in income shall cause fall in demand for Bananas. Here, Income effect shall be negative and substitution effect would also be negative. Demand for bananas shall fall if negative income effect is strong enough to outweigh negative substitution effect.

There are two goods, bananas and potatoes. The price of bananas increases and the price of potatoes decreases. If after the price change a consumer (whose preferences satisfy WARP) can still exactly afford her old consumption bundle, then she will consume at least as many potatoes as before, even if potatoes are a Giffen good.

Suppose two goods, bread and cheese, provide a consumer with utility but only if they are consumed in fixed proportions. What will an increase in the price of bread yield in terms of substitution and income effects, in other words, explain if either effect will occur and what direction they will be in (different or similar direction).?
