base year.

4.(30 points). Suppose that consumer's utility function is u(x,y). The prices of
goods X and Y are PX,PY, and his income is I.
a. Write the consumer's problem.

b. Write the mathematical condition for optimality of consumption bundle
and give a verbal interpretation of it.
The condition for optimal consumption bundle:
Interpretation 1: The left hand side is the slope (in absolute value) of the indifference
curve and the right hand side is the slope of the budget constraint. Thus, at the optimum,
the indifference curve is tangent to the budget constraint.
Interpretation 2: The above condition can be written as

The left hand side is the utility generated by extra dollar spent on X and the right hand
side is the utility from extra dollar spent on Y. The optimal allocation of income between
the two goods requires that those should be the same.

c. Suppose that the utility function is u(x,y)=x3y6. Circle the correct
statement.
i. The consumer will spend 50% of his income on the good X
ii. The consumer will spend $3 on good X and $6 on good Y
The consumer will spend 1/3 of his income on good X
iv. The consumer will spend all his income on good Y
