Let us denote Ben’s daily hours of work by H, and his hours of leisure by N = 24 − H. Suppose that Ben’s only source of income is wages for hours worked. He derives utility from leisure, N, and from the consumption of a composite good, Y. The price of Y is 1. Ben’s utility function is U(Y, N) = ln(Y) + ln(N). (a) Suppose the wage rate is $60 per hour. Write down Ben’s constraint with Y and N as the choice variables.

Consider a worker who consumes one good and has a preference for leisure. She maximizes the utility function u(x, L) = xL, where a represents consumption of the good and L represents leisure. Suppose that this worker can choose any L = [0, 1], and receives income w(1 L); w represents the wage rate. Let p denote the price of the consumption good. In addition to her wage income, the worker also has a fixed income of y ≥ 0. (a) Write down the utility maximization problem for this consumer. (b) Find the Marshallian demands for the consumption good and leisure. (c) Find the indirect utility as a function of p, w, and y.

Mia is a registered nurse. She has 18 hours per day to devote to labor or leisure, and has $20 nonlabor income per day. She is paid $10 per hour for the first 8 hours of work and $15 per hour for overtime (for hours worked over 8 hours). Mia's preferences are represented by U(C, R) = CR utility function, where Cis the amount of dollars she spends on consumer goods and R be the number of hours of leisure that she chooses. Question 1 Part a Assuming she can work as many hours per day as she wishes, draw Mia's indif- ference curves, budget constraints and solve for her optimal consumption and leisure choices. Question 1 Part b Suppose that Mia's wage rate rises to $11 an hour for the first 8 hours. She is still paid $15 per hour for overtime. Again, find her optimal choice. Decompose the total change in demand due to a price change into a substitution effect, ordinary income effect and endowment income effect and graphically demonstrate each effect.

Find the marginal utility of an additional unit of good z for a consumer with utility function u (a, y) = zi yi when their current consumption level is 2 and y = 16.
