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) = (4,1). Decompose the changes of the demand of x1 into substitution effect and income effect.

(d) Draw indifference curves and budget lines to show the substitution effect and income effect in a diagram.

Consider utility function u(x1,x2) =1/4x12 +1/9x22. Suppose the prices of good 1 and good 2 are p1 andp2, and income is m. Do bundles (2, 9) and (4, radical54) lie on the same indifference curve? Evaluate the marginal rate of substitution at (x1,x2) = (8, 9). Does this utility function represent convexpreferences? Would bundle (x1,x2) satisfying (1) MU1/MU2 =p1/p2 and (2) p1x1 + p2x2 =m be an optimal choice? (hint: what does an indifference curve look like?)

A consumer’s preferences over two goods (x1,x2) are represented by the utility function ux1,x2=5x1+2x2. The income he allocates for the consumption of these two goods is m. The prices of the two goods are p1 and p2, respectively. Determine the monotonicity and convexity of these preferences and briefly define what they mean. Interpret the marginal rate of substitution (MRS(x1,x2)) between the two goods for this consumer.   For any p1, p2, and m, calculate the Marshallian demand functions of x1 and...

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 ?...

There are two goods, Good 1 and Good 2, with positive prices p1 and p2. A consumer has the utility function U(x1, x2) = min{2x1, 5x2}, where “min” is the minimum function, and x1 and x2 are the amounts she consumes of Good 1 and Good 2. Her income is M > 0. (a) What condition must be true of x1 and x2, in any utility-maximising bundle the consumer chooses? Your answer should be an equation involving (at least) these...

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...
