Suppose that a decision-maker’s preferences over the set A={a, b, c} are represented by the payoff function u for which u(a) = 0, u(b) = 1, and u(c) = 4.
(a) Give another example of a function f:A→R that represents the decision-maker’s preferences.
(b) Is there a function that represents the decision-maker’s preferences and assigns negative numbers to all elements of A?
Solution-
(a) Set A = {a,b,c}
u(a)= 0
u(b)= 1
u(c)= 4
Example of function f:A->R is as follows-
R={(a,0), (b,1), (c,4)}
Where, R= f(x), X is the subset of A.
(b) Function that represents the decission's maker prefrences and assigns negative number to all elements of A-
f: A->R-1 = {(0,a), (1,b), (4,c)}

please answer step by step EXERCISE 149.2 (Normalized Bernoulli payoff functions) Suppose that a decision- maker's preferences can be represented by the expected value of the Bernoulli pay- off function u. Find a Bernoulli payoff function whose expected value represents the decision-maker's preferences and assigns a payoff of 1 to the best outcome and a payoff of 0 to the worst outcome.
Suppose a consumer’s preferences over goods 1 and 2 are represented by the utility function U(x1, x2) = (x1 + x2) 3 . Draw an indifference curve for this consumer and indicate its slope.
2. An individual's preferences over food (F) and clothing (C) are represented by the utility function U(F, C)FiC. She currently has 9 units of food and 8 units of clothing According to her MRS, she would be willing to give up a maximum of 4/3 units of food to obtain one more piece of clothing. a. True b. False
Suppose that a decision maker’s risk attitude toward monetary gains or losses x given by the utility function U(x) = (x + 10000)^0.5. If there is a 5% chance that the decision maker's car, valued at $8000, will be totaled during the next year, what is the most that she would be willing to pay each year for an insurance policy that completely covers the potential loss of her vehicle? Please round all answers (also intermediate results to 2 decimals)...

Suppose Bill has preferences over chocolate,x, and ice cream,y, that are represented by the Cobb-Douglas utility function u(x, y) =x^2 y. 1. Write down two other Cobb-Douglas utility functions, besides the one above, that represent Bill’s preferences. 2. Write down two more Cobb-Douglas utility functions that do NOT represent Bill’s prefer- ences. 3. Draw 3 indifference curves that represents Bill’s preferences at 3 different levels of satsifaction. 4. What is Bill’s marginal rate of substitution between chocolate and ice cream?...
Utility Maximization with Non-Monotone Preferences Suppose there are two goods, coffee (C) and tea (T). The consumption set is R 2 +, so both goods can be consumed in arbitrary non-negative quantities. Abdul owns 2000 grams of coffee but does not own any tea. He has no other wealth. The price of coffee is pC = 2 (in Dhs per gram) and the price of tea is pT > 0 (in Dhs per gram). Abdul can sell coffee to earn...
Suppose Sansa lives for two periods. Her preferences are represented as follows: u(c1, c2) = (1+0.8VC2 where cı is today's consumption level and c2 is tomorrow's consumption level. Suppose Bob's income today is yı = 100 and his income tomorrow is y2 = 190. Interest rate is denoted by r. 1. Write down Sansa's optimization problem including the budget set. 2. Determine Sansa's optimal consumption bundle (Cl*, C2*) as a function of r.
4. Suppose preferences are represented by the Cobb-Douglas utility function, u(x1x2) = xx-. a) Show that marginal utility is decreasing in X and X2. What is the interpretation of this property? b) Calculate the marginal rate of substitution c) Assuming an interior solution, solve for the Marshallian demand functions.
