3. Suppose the individual has a utility function In(c) where c is consumption and In(·)is the natural logarithm function (that is, logarithm with base e; which is a verypopular utility function used in both economics and finance research). Calculatethe expected utility from each lottery.4. For this specific example, which lottery offers higher value (in terms of expectedutility) and what is it about the shape of the utility function that yields this result? Consider two lotteries. Lottery A is such that an individual receives a prize of 1.25units of a consumption good with 50% probability and 0.75 units of the consumptiongood with 50% probability. Lottery B presents the winner with a prize of 1.5 units ofa consumption good with 50% probability and a prize of 0.5 units of the consumptiongood with 50% probability.

Lottery A: Prize = 1.25 units with probability 0.5 Prize = 0.75 units with probability 0.5 Lottery…

Consider the lottery that assigns a probability T of obtaining a level of consumption CH and a probability 1-T an individual facing such a lottery with utility function u(c) that has the properties that more is better (that is, a strictly positive marginal utility of consumption at all levels of c) and diminishing marginal utility of consumption, u"(c) CL. Consider du(c) for the first derivative of the utility function with respect to dc du(c) du' (c) consumption and u"(c) (which is also the derivative of the first derivative of the utility function). to be the second derivative of the utility function dc dc2 1. Provide a definition for the certainty equivalent level of consumption for the simple lottery described above.
6. If intertemporal preferences are consistent and the lifetime utility function is additive, then the discount function 8(t) must be (a) bounded (b) exponential (c) hyperbolic (d) linear (e) logarithmic
A consumer is having a monotonic preference. What can you say about his preference on these bundles (10,10) (10,9) (9,9)
Economics Consider two friends Anna and Elsa whose gains and losses are listed as follows: Anna's investment is worth $2.5 million (decreased from $3.5 to $2.5 million) Elsa's investment is worth $2.2 million (increased from $2 to $2.2 million) For each of them write down the reference utility function (First determine the reference point (use a parameter) and derive reference utility function for each).
A consumer has the following utility function: U(x.y)=x(y+1), where x and y are quantities of two consumption goods whose prices are Px and Py, respectively. The consumer also has a budget of B. Therefore, the Lagrangian for this consumer is x(y + 1) + X(B – Prx – Py) (a) Verify that this is a maximum by checking the second-order conditions. By substituting x* and y* into the utility function, find an expression for the indirect utility function U* = U(Pr, Py, B) and derive an expression for the expenditure function E = E(Pr, Py, U*) (b) This problem could be recast as the following dual problem Min Prx + Pyy Subject to æ(y + 1) = U* Find the values of x and y that solve this minimization problem and show that the values of x and y are equal to the partial derivatives of the expenditure function, ðE/ðP, and ðE/ðP, respectively.
1. Rosie has just written a book. Assume that her preferences are consistent with expected utility theory. There is 30% chance that her book will be a best-seller and make $500,000 in profit (after the costs of production) and a 70% chance it will just break even (i.e. no profit after the costs of production). Her current income is $150,000 (which she will receive regardless of what happens with her book) and her utility function is u (I) = ln (I) (a) Is Rosie risk-averse, risk-neutral, or risk-loving? How do you know? (b) Assume that Rosie will receive all of the profits (if any) from her book. Draw a diagram illustrating (i) Rosie's total income if her book just breaks even, (ii) her total income if her book is a best-seller, (iii) her expected income, (iv) her expected utility, (v) her certainty equivalent, and (vi) her risk premium. (c) Compute the numerical values associated with each of the six amounts you found in (b). (d) Acme Publishing Company has offered Rosie $100,000 for…
Victoria founded a start-up several years ago, together with her Macedonian friends. At first, she was fairly poor and therefore very afraid of taking risks. Any negative shock could send the company into bankruptcy. Nowadays her business is thriving, stretching across several markets from Europe to Asia. Victoria no longer worries about taking monetary risks. In fact she enjoys a good gamble over horse races from time to time. How would you draw Victoria's utility function in a way that describes her changing taste for risk as her wealth increased? Please draw a graph and comment. Please do fast ASAP fast

i. Write down the Lagrangian form and solve the utility maximization problem. ii. Assume that the income increases from 100 to $101. What is the increase in the optimal value of u(x,y)?
Suppose Katie buys the bundle (20,9) from the budget line 3x_1 + 5x_2 = 105. When the price of good 1 changes to p1 = 6 and the price of good 2 remains the same, she buys the bundle (5,15). On a later date when p1 = 5 and p2 = 4, by observing Katie’s choices we can say that the Weak Axiom of Revealed Preference (WARP) is violated if a) She buys the bundle (10,15). b) She buys the bundle (15,10) c) She buys the bundle (23,6) d) She buys the bundle (25,25). e) None of the above choices violates WARP.
