Why do we expect that indifference curves will never cross?
Can you explain why taking a monotonic transformation of a utility function doesn’t change the marginal rate of substitution?
Suppose we have the following utility
function: U(x,y)=x^O.33 y^0.67
1) What is the Marginal utility of x? Marginal
utility of y?
2) Comment on how the marginal utility of
each changes as x increases and discuss
why that makes sense.
3) Does this utility function follow the more
is better rule? How do you know?
4) What is the marginal rate of substitution
(MRS)? What do we know about the shape
of the indifference curve given this MRS?
5) Now suppose we have a new utility
function: U(x,y)=x+y. What type of goods
are these? Explain.

- Mrs. Griffiths earns $5000 a week and spends her entire income on dresses and handbags, since these are the only two items that provide her utility. Furthermore, Mrs. Griffiths insists that for every dress she buys, she must also buy a handbag. Draw an indifference curve showing the optimum choice. Label the optimum as point A. What would be the marginal rate of substitution at the point that corresponds to the optimal consumption choice? Interpret the marginal rate of substitutionarrow_forwardJulio receives utility from consuming food (F) and clothing (C) as given by the utility function U(F,C) = FC. In addition, the price of food is $2 per unit, the price of clothing is $7 per unit, and Julio's weekly income is $50. What is Julio's marginal rate of substitution of food for clothing when utility is maximized? Explain. Julio's marginal rate of substitution equals A. 3.50, which is the price of clothing divided by the price of food. B. 0.29, which is the price of food divided by the price of clothing. C. 0.29, which is the price of clothing divided by the price of food. D. 3.50, which is (minus) the slope of the budget line. E. 3.50, which is Julio's level of satisfaction.
