1. All feasible bundles will maximize consumer utility:

True

False

2. The point to the right of the budget constraint is infeasible.

True

False

3. For a budget constraint involving 2 goods, good X is on the x-axis and good Y on the y-axis. If the price of good X increases,

A.the slope of the budget constraint becomes steeper and the x-intercept of the budget constraint slides in along the x-axis.

B.the slope of the budget constraint becomes flatter and the x-intercept of the budget constraint slides out along the y-axis.

C.the budget constraint shifts out, but its slope does not change.

D. the budget constraint shifts in, but its slope does not change.

4. If the consumer's income increases:

A. the slope of the budget constraint becomes steeper and the x-intercept of the budget constraint slides in along the x-axis.

B.the slope of the budget constraint becomes flatter and the x-intercept of the budget constraint slides out along the x-axis.

C. the budget constraint shifts out, but its slope does not change.

D. the budget constraint shifts in, but its slope does not change.

5. What is the tangency condition to optimize utility, given there is a budget constraint?

A.Income = ?x ?x + ?y ?y

B. when the marginal rate of substitution is equal to income

C. Slope of indifference curve=Slope of budget constraint

Expert Solution

Ans 1: False, not all feasible bundles maximizes the utility. When Indifference curve is tangent to budget line, at that point, only those bundles maximizes the consumer's utility.

Ans 2: True. The bundles which are beyond the reach of budget line, to the right of it, are not affordable.

Ans 3: A. The slope of the budget constraint becomes steeper and the x-intercept of the budget constraint slides in along the x-axis. (With an increase in price of good x, he will consume less of good x)

Ans 4: C. The budget constraint shifts out, but its slope does not change. (The slope of the budget line is the ratio of prices of two goods. So, when there is change in prices of the good only then the slope of the budget line changes. An increase in the income shifts the budget line to right side. The shift will be parallel and indicates more can be consumed).

Ans 5: C. Slope of indifference curve=Slope of budget constraint (This is the consumer's equilibrium situation. The slope of the indifference curve is MRS whereas, the slope of the budget line is ratio of prices of two goods. Therefore,

MRS = Px / Py

Explain why the statement is true or false; Affordable bundles for a consumer only include those bundles on or below the budget line itself.

2. Why is it that the consumer can maximize total net utility only if the purchase quantity brings marginal utility as close as possible to equality with price? 3. Use the law of diminishing marginal utility to explain why Domino's and Pizza Hut allow the purchase of a second pizza for only $5 when one pays full price (around $10) for the first pizza. Why not simply charge $7 a pizza instead? Explain why the long-run average cost is typically...

What is the condition on consumer utility that is met when consumers maximize utility

Problem 1 What is the condition on consumer utility that is met when consumers maximize utility (hint: it is a formula). Describe the behavior of the consumer that this formula represents (what are they doing and why is it an optimum). Problem 2 What is the goal of the firm? What is the condition that is met when firms achieve this goal? Describe in words why this condition leads to an optimum for the firm.

A consumer is choosing among bundles of two goods. Their utility function is u = x1 − x2. They have cashm = 20 and the prices are p1 = 5 and p2 = 4. Sketch their budget set. Indicate their optimal choice of bundle. Sketch a couple of their indifference curves, including the one that passes through their optimal choice.

Lyuba has preferences over peonies (p) and tulips (t). The following list shows all feasible bundles that Lyuba can consume in a month: A = (pA,tA) = (1,3), B = (pB,tB) = (3,1), C = (pB,tB) = (2,2). If Lyubas preferences are given by: A is indifferent to B, C is strictly preferred to A and C is strictly preferred to B, then: (a) A function that represents Lyuba’s preferences is U(p,t)=3p+t. (b) A function that represents Lyuba’s preferences is...
