Suppose Joe has preferences over income given by U(I) = ln(I).

Furthermore, suppose there are two states of the world and that Joe believes the state 1 will occur with probability equal to 0.25 and state 2 will occur with probability 0.75.

1. If Joe's income endowment in the two states is given by (I₁, I₂) = (80, 110) and he is able buy z₁ = 40 extra income in state 1 by selling z₂ = -20 income in state 2, what is his expected utility?

2. What is the |slope| of Joe's indifference curve at the income allocation from problem #1?

3. If Joe decided to buy and sell A-D securities so that he faced no income risk at all in the future, what would be the |slope| of his indifference curve at that point?

Suppose preferences for consumption and leisure are: u(c, l) = ln(c) + θ ln(l) and households solve: maxc,l u(c, l) s.t. c=w(1−τ)(1−l)+T Now suppose that in both Europe and the US we have: θ = 1.54 w=1 but in the US we have: τ = 0.34 T = 0.102 while in Europe we have: τ = 0.53 T = 0.124 The values for τ and T above are not arbitrary. If you did the calculations correctly, you should find that...

Suppose an agent has preferences represented by the utility function: U(x1, x2) =1/5 ln (x1) + 4/5 ln (x2) The price of x1 is 6 and the price of x2 is 12, and income is 100. a) What is the consumer’s optimal consumption bundle? b) Suppose the price of x2 is now 4, what is the consumer’s new best feasible bundle?

Suppose a person has utility function, prices, and income: U(a,B) = 2 ln(A) + ln(B), Pb=1 and m=12. Draw her price offer curve and explain. Hint: it may be useful to think about the number of B's she purchases as Pa changes.

Consider a consumer with preferences over two goods (good x and good y) given by u ( x , y ) = x ⋅ y. Given income of I and price of good yas $ P yper pound and price of good xgiven as $ P xper pound, the consumer chooses the optimal consumption bundle given as x ∗ = I 2 P x and y ∗ = I 2 P y . Given P x = $ 1per pound...

Suppose an agent has preferences represented by the following utility function: u(x1, x2) = 1/4 ln(x1) + 3/4 ln(x2) The price of good x1 is 2, the price of good x2 is 6, and income is 40. a) What is the consumers best feasible bundle (ie, his optimal consumption bundle)? b) Interpret the consumer’s marginal rate of substitution at the best feasible bundle found in part a).

Priya has preferences over consumption and leisure given by U(C,L) = CL. Her total number of available hours in a given week is 100. Her non-labour income is £800. If she chooses to work, she earns w = £20 per hour. If the government starts a welfare policy that pays an amount of £B to all non-workers and pays 0 to all workers, at what value of B will Priya opt out of the labour force in order to go...

Suppose a consumer has preferences given by U(X,Y) = MIN[2X,Y]. Suppose PX = 1 and PY = 2. Draw the Income Consumption Curve for this consumer for income values • M = 100 • M = 200 • M = 300 To do this, carefully draw the budget constraints associated with each of the prices for good X, and indicate the bundle that the consumer chooses in each case. Also, be sure to label your graph accurately.

A worker has a utility function over income U(I) = √ I. She is picking between two jobs for the following year. Job X pays $40,000; she can get this job for sure. She is also considering Job Y; there are other candidates for this job, and the probability of not getting it during the hiring process is 0.2 (she would get no income at all if that happened, and the process concludes after Job X’s deadline). If she gets...

Let's say that my utility function over wealth is LaTeX: U=\ln\left(W\right) U = ln ⁡ ( W ) where W is my wealth in dollars. Suppose I currently have $1,000,000 in wealth (oh ye-ah), but my friend Rob offers me an opportunity to invest in his new start-up creating autonomous window-washing robots. [Note: the robots part is a kinda-true story. Ask me sometime!] If the start-up is successful—and we estimate it has a 10 percent chance of success—Rob will pay...

Suppose that an individual has wealth of $20,000 and utility function U(W) = ln(W), where ln(W) indicates the natural logarithm of wealth. What is the maximum amount this individual would pay for full insurance to cover a loss of $5,000 with probability 0.10?
