Suppose that a consumer has perfect complements, or Leontief, preferences over bundles of non-negative amounts of each of two commodities. The consumer’s consumption set is R^2(positive). The consumer’s preferences can be represented by a utility function of the form U(x1, x2) = min(x1, x2).

1. Illustrate the consumer’s weak preference set for an arbitrary (but fixed) utility level U.

2. Illustrate a representative iso-expenditure line for the consumer.

3. Illustrate the consumer’s utility-constrained expenditure minimisation problem.

4. Illustrate the derivation of the consumer’s compensated (or Hicksian) demand curve for commodity one.

5. Find the algebraic expression for the consumer’s compensated (or Hicksian) demand functions for commodity one and commodity two?

6. Find an algebraic expression for the consumer’s expenditure function.

Homework Answers

Answer #1

The indifference curves will be L shaped as increasing consumption of any good without the other keeps the utility same. There will be kinks at the 45 degree line. The weak preference sets will be in the northeast direction of the curves, including the curve.

As there is no substitution effect the Hicksian and Marshallian demand functions will be the same. Optimum will be where both goods are equal. Using that, all required functions are derived

Suppose that a consumer has preferences over bundles of non-negative amounts of each two goods, x1 and x2, that can be represented by a quasi-linear utility function of the form U(x1,x2)=x1 +√x2. The consumer is a price taker who faces a price per unit of good one that is equal to $p1 and a price per unit of good two that is equal to $p2. An- swer each of the following questions. To keep things relatively simple, focus only on...

Consider a consumer that has preferences defined over bundles of non-negative amounts of each of two commodities. The consumer’s consumption set is R2+. Suppose that the consumer’s preferences can be represented by a utility func- tion, U(x1,x2). We could imagine a three dimensional graph in which the “base” axes are the quantity of commodity one available to the consumer (q1) and the quantity of commodity two available to the consumer (q2) respec- tively. The third axis will be the “height”...

Suppose that a consumer whose preferences are defined over two commodities has an endogenous budget consisting only of those commodities. Draw the budget constraint for this consumer so that x1 on the horizontal axis is x2 on the vertical axis. Mark the basket owned by the consumer as Point E on this budget. Let this also be the consumer's optimal solution (non-Vertex solution). how is it possible for the consumer to come to a higher level of benefit when the...

A consumer has utility function U(x1,x2)= x1x2 / (x1 + x2) (a) Solve the utility maximization problem. Construct the Marshallian demand function D(p,I) and show that the indirect utility function is V (p, I) = I / (p1+ 2 * sqrt (p1*p2) + p2) (b) Find the corresponding expenditure function e(p; u). HINT: Holding p fixed, V and e are inverses. So you can find the expenditure function by working with the answer to part (a). (c) Construct the Hicksian...

4. Suppose a consumer has perfect substitutes preference such that good x1 is twice as valuable as to the consumer as good x2. (a) Find a utility function that represents this consumer’s preference. (b) Does this consumer’s preference satisfy the convexity and the strong convex- ity? (c) The initial prices of x1 and x2 are given as (p1, p2) = (1, 1), and the consumer’s income is m > 0. The prices are changed, and the new prices are (p1,p2)...

A consumer likes two goods; good 1 and good 2. the consumer’s preferences are described the by the cobb-douglass utility function U = (c1,c2) = c1α,c21-α Where c1 denotes consumption of good 1, c2 denotes consumption of good 2, and parameter α lies between zero and one; 1>α>0. Let I denote consumer’s income, let p1 denotes the price of good 1, and p2 denotes the price of good 2. Then the consumer can be viewed as choosing c1 and c2...

Suppose a consumer has quasi-linear utility: u(x1,x2 ) = 3x1^2/3 + x2 . The marginal utilities are MU1(x) = 2x1^−1/3 and MU2 (x) = 1. Throughout this problem, assume p2 = 1 1.(a) Sketch an indifference curve for these preferences (label axes and intercepts). (b) Compute the marginal rate of substitution. (c) Assume w ≥ 8/p1^2 . Find the optimal bundle (this will be a function of p1 and w). Why do we need the assumption w ≥ 8/p1^2 ?...

Homer is a deeply committed lover of chocolate. Assume his preferences are Cobb-Douglas over chocolate bars (denoted by C on the x-axis) and a numeraire good (note: we use the notion of a numeraire good to represent spending on all other consumption goods – in this example, that means everything other than chocolate bars – its price is always $1). a. Homer earns a salary that provides him a monthly income of $360. Last month, when the price of a...

2. Yan has preferences over chocolate(x)and vanilla(y)ice cream that are represented by the following utility function: u(x,y) = xy4 3 Notice the power (4/3) just affects good y. (a) Yan is an ice cream connoisseur, meaning, when deciding how much ice cream to buy, there is a minimum level of utility he must reach with ice cream consumption. But he doesn’t want to spend too much money because he is a graduate student. Setup Yan’s constrained expenditure minimization problem. (1...
