Suppose a consumer has y = 100 and y0 = 150. She pays t = 20 and t0 = 30
in taxes. She faces an interest rate of 5% i.e. r = 0:05. Her utility function is
given by: U = ac + c0, where a > (1 + r).
(a) Assume that she cannot borrow. Determine her optimal choice of c and c0.
Show it in a diagram.
(b) Continue to assume that she cannot borrow. Now her current-period tax
is reduced to zero and future-period tax is increased such that the present
value of lifetime taxes does not change. Find her new optimal choice of c
and c0. Does Recardian Equivalence hold in this case? Why or why not?
(c) Finally assume that she does not face any borrowing constraint. Find her
optimal consumption bundle.

Assume a consumer who has current-period income y=200, future period income y’=150, current taxes t = 40, and future taxes t’= 50, and faces a market interest rate of r=5 percent or .05. The consumer would like to consume such that c’=c*(1+r) if possible. However, this consumer is faced with a credit market imperfection, in that no borrowing is allowed. That is s must be greater or equal to zero.   a. Show the consumer’s lifetime budget constraint and indifference curves...

Draw the Price-Consumption Curve for this consumer for income values Px =1, Px = 2, and Px = 5. Your graph should accurately draw the budget constraints for each income level and specifically label the bundles that the consumer chooses for each income level.

Suppose a consumer has preferences given by U(X,Y) = MIN[2X,Y]. Suppose PX = 1 and PY = 2. Draw the Income Consumption Curve for this consumer for income values • M = 100 • M = 200 • M = 300 To do this, carefully draw the budget constraints associated with each of the prices for good X, and indicate the bundle that the consumer chooses in each case. Also, be sure to label your graph accurately.
