e)
We have to assign the utilities in such a way that we give higher magnitude to those alternatives whose rankings are higher in preference relation, so that preference relation is preserved.
Preference relation of Individual 1 :
so we well assign highest utility to A, say 6 then to B and C respectively 4 & 2.
Entities | Utility |
---|---|
A | 6 |
B | 4 |
C | 2 |
Similarly,
Preference relation of Individual 2 :
hence, we will assign the utility values accordingly,
Entities | Utility |
---|---|
A | 5 |
B | 3 |
C | 7 |
f)
In ordinal utility concept one can only order the preference relation of the consumer/individual but can not assign the cardinal numbers to them.
eg, for individual-1 the ordering of preference relation is,
g)
The care that we should keep in mind is that it should be positive monotone transformation.That is,
where is the old assignment of utilities and is the new assignment of utilities to the preference relation.
Also a and b are constants here.
for a = 2 and b = 1 our new assignment of utilities will be,
j)
No, we don't need to assume the utilities to be cardinal in order to make the given statement because it can be easily observed with the ordinal utility approach.
We have for Individual 1 :
For, Individual 2 :
so, For both of them .

2. A hospital administrator is making a decision regarding the hospital’s policy of treating individuals who have no insurance coverage. The policy involves examination of a prospective patient’s financial resources. The issue is what level of net worth should be required in order for the patient to be provided treatment. Clearly, there are two competing objectives in this decision. One is to maximize the hospital’s revenue, and the other is to provide as much care as possible to the uninsured...
I consider an economy with two individuals (1 and 2). A, B, and C are three points that belong to the utility possibility frontier of the economy. The individual utilities (Ul. U2) at the three points are as follows: Pointsul U2 A 4 21 B 8 17 C 14 6 Now consider point D. Pointul U2 D 9 15 a. Does point D lie on the utility possibility frontier? How does the answer change if you know the utility possibility...
2) Consider an Exchange economy composed of two individuals A and B and two goodsx1 and x2. Individual A has an endowment of W(3,5) and individual B has an endowment of Wa^- (3,3). A's utility function is given byUA Xx2. Suppose that B is neutral about x1 (neither increasing nor decreasing the amount of x1 affects her utility) and she prefers more of x2 to less. Specifv a utility function for B. Eind the equilibrium price and allocations. 3) Consider...
Example Consider a society with 2 individuals A and B and 2 goods 1 and 2. The total available amount of good 1 and 2 is 9 units and 12 units. The utility function for the consumers is given by U(x)=(x,1)(x) for i=A,B. a) Show this economy in an Edgeworth box, including indifference curves. b) Define the meaning of the following notions; Pareto- efficient allocation, Pareto set, and contract curve. c) Find and draw the contract curve for this economy....
2. Consider an economy with three individuals who are identical except for their income: individual 1 has one dollars, individual 2 has two dollars, and individual 3 has three dollars. Let the monetary utility function be U x1/2, where x is the income. If you are a social planner who use a utilitarian social welfare function (see Chapter 2, p55 for a definition) to measure social welfare, will you allow individual 1 to steal one dollar from individual 3?
Suppose there are two individuals who share a house and garden. They have decided to hire a gardener to take care of their front and backyard, but they will each individually decide how much to contribute to paying the gardener. The gardener works for $50 an hour. They both have an income of $4,000 and they both value a tidy garden (measured by the hours G that the gardener works) and private good. Person 1's utility function is given by...

1. A group of individuals were classified according to two factors: presence or absence of a disease and presence or absence of a set of symptoms. Disease Symptoms Yes No Yes 25 125 No 5 15 An individual is randomly selected from the group. Given that the disease is present, what is the probability that the symptoms are present? Select one: a. 0.83 b. 0.70 c. 0.88 d. 0.75 2. A corporation receives a particular part in shipments of 100....
1. You are studying a population of sandblossoms (Linanthus parryae) that has individuals with blue and white flowers. The allele for white flowers (A) is dominant to the allele for blue flowers (a). In the population you survey, 91 out of 100 individuals have white flowers. Based on this information: a. Calculate the frequency of the A and a alleles. b. Calculate the numbers of each genotype. 2. A population of snapdragons (Antirrhinum hispanicum) has two additive alleles for flower...
An Individual lives for two periods, 1 and 2. In the first he works and earn an income of M. In the second he is retired and has no income His/her life time utility is a function of how much he consumes in the two periods. Cydenotes consumption in period 1 and 2 consumption in period 2. (Hint: If you want to, you can view and treat C and C2 as any pair of "goods", eg, good x and y)....
