7.A college football coach says that given any two linemen A and B, he always prefers the one who is bigger and faster. Is this preference relation transitive? Is it complete? 8.Explain why convex preferences means that “averages are preferred to extremes. 9.If good 1 is a “neutral,” what is its marginal rate of substitution for good 2?
What do we mean by well-behaved preferences? How do the indifference curves look like for suchpreferences? Provide an example, in terms of a utility function, where preferences are not well-behavedand illustrate. Provide a figure with indifference curves and a budget line where there are exactly twosolutions to the utility maximization problem.
No written by hand solution Assume Fred has the following preference relation on [0, 1]: x ≿ y if and only if x ≤ y for all x ̸= 1 and y ̸= 1; and 1 ≻ z for all z ∈ (0, 1), 1 ∼ 1 and 0 ≻ 1. Does there exists a utility representation for this preference relation? If yes, provide a utility function. If no, explain. Show your work.
10. Consider the utility function U(x, y) = xy + x. Which of the following bundles is noton the same indifference curves as the others. Note: The first entry is the amount of x, thesecond is the amount of y.(a) (5,1)(b) (2,4)(c) (4,2)(d) (2.5,3)
6 B. Calculate and represent the indifference curves that pass through the bundles (x, y) = (1,1) and (x, y) = (1,2) of individuals whose preferences are represented by the functions of utility:
The primary goal of very consumer is to maximize satisfaction. Explain, how a consumer achievesequilibrium using:a) Indifference curve analysisb) Marginal Utility theory
Assume that an individual has convex indifference curves (i.e. diminishing MRS). Suppose the individual has $3 to spend on good #1 and good #2. In addition, suppose we know that at the bundle where q1=1 and q2=1, the marginal utility of good #1 is 2 utils and the marginal utility of good #2 is 1 util. Given this information, which set of prices would this individual prefer to face? A. p1=1 and p2=2 B. p1=2 and p2=1 C. p1=2 and p2=2
16. Utility functions are simply mathematical representations of preferences.(a) True(b) False
Depart from the represented preferences U(x,y)= min {x, 4y} 1. Draw two indifference curves for the given utility function and show the preferred points, by providing examples. 2. Explain mathematically the MRS for the different parts of this type of IC.
Q.4. Example 1.D.1: Suppose that X = {x,y,z}, B = {{x,y}, {y,z},{x,z}}, C({x,y}_ = {x}, C({y,z}) = {y} and C({x,z})={z} This choice structure satisfies the weak axiom. Nevertheless, we cannot have rationalizing preferences. How do we know if this choice structure satisfies the weak axiom? Given the C({x,y}) = x, C({y,z}), shouldn't C({x,z}) = x? if we have to always make the same choice based on WARP.
