Consumption theory makes extensive use of indifference curves and budget lines to explain consumer decisions. Assume a 2-good case (X and Y) in which a consumer has traditional smooth convex indifference curves. (a) Explain how the consumer's budget set and budget line are obtained if their money budget (M) is £100 and the prices for goods X and Y (PX, PY) are both £5 per unit. Your explanation should also include reference to the market rate of substitution. Provide formulae and graphs where appropriate. (b) Explain how the budget line would change in the case of (i) an increase in the price of good X, and (ii) an increase the money budget. Provide formulae and graphs where appropriate. (c) Given the prices and budget stated in part (a), you are told that the consumer has chosen to spend their budget on 10 units of X and 10 units of Y. Explain how this optimum consumption point is identified using economic analysis. Your explanation should also include reference to the marginal rate of substitution. Provide formulae and graphs where appropriate.

Question

Consumption theory makes extensive use of
indifference curves and budget lines to
explain consumer decisions. Assume a 2-good
case (X and Y) in which a consumer has
traditional smooth convex indifference curves.
(a) Explain how the consumer's budget set
and budget line are obtained if their money
budget (M) is £100 and the prices for goods X
and Y (PX, PY) are both £5 per unit. Your
explanation should also include reference to
the market rate of substitution. Provide
formulae and graphs where appropriate.
(b) Explain how the budget line would change
in the case of (i) an increase in the price of
good X, and (ii) an increase the money
budget. Provide formulae and graphs where
appropriate.
(c) Given the prices and budget stated in part
(a), you are told that the consumer has chosen
to spend their budget on 10 units of X and 10
units of Y. Explain how this optimum
consumption point is identified using
economic analysis. Your explanation should
also include reference to the marginal rate of
substitution. Provide formulae and graphs
where appropriate.

Question 3: Samantha has $3,000 to spend on two goods: sandwiches and beer. The price of a sandwich is $6 and price of a beer is $5. a) Draw Samantha's budget line. Put beer on the horizontal axis. b) If Samantha's optimal consumption bundle contains 400 sandwiches, how many beer does her optimal consumption bundle contain? Show her optimal consumption in the graph above. c) Draw Samantha's indifference curve crossing her optimal consumption bundle.
A consumer’s utility only depends on the consumption of goods A and B according to the following Cobb-Douglass utility function: U(A, B) = A1/4 B 3/4. The price of goods A and B are $20 and $40, respectively. The consumer has a budget of $1200 that he can use to consume the two goods. a. Write down the budget constraint and plot it. b. Calculate the optimal bundle and maximized utility for the consumer. c. A new tax of $10 is imposed on the price of good B. Compute the new optimal bundle of good A and B for the same consumer. What is the utility loss due to the tax? d. Show that the consumer would prefer a lump sum income tax that raises the same revenue as the tax on good B. Note:- Do not provide handwritten solution.

A consumer currently spends a given budget on two goods, X and Y, in such quantities that the marginal utility of X is 15 and the marginal utility of Y is 8.

The utility-maximizing rule suggests that this consumer should Multiple Choice a. decrease consumption of product X and increase consumption of product Y. b. increase consumption of product X and increase consumption of product Y. c. decrease consumption of product Y and increase consumption of product X. d. stick with the current consumption mix because it yields maximum utility.
