ii) the income effect of the price change on bananas. Ans: the increase in the price of bananas, with a fixed income and a constant price of scones, means that if Rajan chooses to purchase any bananas his real income is now lower than it was before the price increase - his budget set has shrunk. This is similar to a change in money income: the original optimal bundle is no longer attainable, and he must move to a new, lower, IC. The income effect of the price change on bananas reflects the change in quantity of bananas purchased as a result of the movement from the original to the new indifference curve. f) (4) Identify the effects in (e) on your diagram. Ans: substitution effect measured along original IC, from MRS = 6/5 to MRS= 12/5; income effect measured from original to new, lower, IC, with MRS=12/5.

Explain why or why not (with reference to the diagram if you wish). Ans: No, he would not choose his initial bundle. The change in relative prices causes him to adjust his consumption to restore MRS = price ratio. Even if the original bundle is now just affordable, Rajan could attain a higher utility by purchasing fewer bananas, and more scones, than he originally did.
