Consider a preference over bundles (x1,x2), where x1 ≥ 0 and x2 ≥ 0. Suppose the rational agent with this preference is indifferent among the following three bundles:
(x1,x2), (x1 + 1, x2 - b), (x1 + 2, x2 - c)
where 0 < b < c < x2. Note that these three bundles must lie on the same indifference curve. Suppose also that the agent’s preference is strictly monotone and strictly convex. What does this imply about the relationship b and c?

Consider my preference over bundles (x1,x2), where x〉 0 and x2 〉。. You do not know all of the strict/indifferent pairwise comparisons in my preference, but you do know the following: Suppose you also know that my preference is rational, strictly monotonic, and strictly convex. Can you infer how my preference compares the following pairs? Explain each one briefly. a) (3,7) versus (1,7), b) (3,7) versus (7,5) c) (1,7) versus (4,6) d) (7,5)...
Please give detailed steps. Thank you.

2. Assume a consumer has as preference relation represented by u(x1, x2) = axi + bx2 with x E C = R4, and a, b > 0. Answer the following: a. Show the preference relation this consumer is convex and strictly monotonic show preferences are not strictly convex for this consumer. b. Graph the indifference curves for this consumer. Now, solve for an explicit expression for the indiffence curve (i.e., x (x1; ū) i constructed in class for an indifference...
Question 2. Consider the following 8 bundles of goods x and y: A = (8,4) B = (5,6) C = (5,9) D = (10,3) E =(1,4) F =(6,5) G=(2,8) H =(7,8) (a) Come up with an example of a utility function that will produce the following order of preference for the bundles, where H is most preferred, A and G are equally preferred, and E is least preferred. H , C , B , F , A = G ,...
2.3 Choice III Consider a consumer whose preference is represented by the utility function where A 0 and B 0. a) What is the consumer's marginal rate of substitution? b) If the consumer has income m and faces prices p-A and p - B, what are her optimal bundles? (There may be one, or more than one.) Draw a graph that illustrates this situation, including the budget line and the relevant indifference curve(s). c) If the consumer has income m...
Suppose there are two goods, food and clothing. My preference has the following properties: 1. I am rational. 2. I need at least one unit of food and one unit of clothing in order to survive 3. I strictly prefer surviving over not surviving. 4. I am indifferent over all situations in which I do not survive. 5. When I have strictly more than one unit of each good, I satisfy strict monotonicity and strict convexity. 2 6. When I...
Problem 2 Suppose that Prof. Wu faces three consumption bundles A-1 apples,3 bananas), . B (3 apple, 2 bananas), . C (4 apples, 2 bananas) Assume that Prof. Wu prefers C to B and he is indifferent between Λ and B 1) If Prof. Wu is rational, what additional conditions you need to impose on Prof. Wu's pref erences? Explain why after adding those conditions, we can say Prof. Wu is rational 2) Depict the three consumption bundles on a...
1. Consider a utility function u(x1, x2) = x1 + (x2)^a where a > 0. (a) Show that if a < 1, then preferences are convex. (b) Show that if a = 1, then preferences have perfect substitutes form. (c) Show that if a > 1, then preferences are concave. (d) For each case, explain how you would solve for the optimal bundle.
