Joanna is playing blackjack for real money. She has reference-dependent preferences overmoney: if her earnings are m and her reference point is r, then her utility is v(m − r), wherethe value function v satisfies v(x) = √x for x ≥ 0, and v(x) = −2√−x for x ≤ 0a) Graph Joanna’s utility function as a function of m − rb) Does Joanna’s utility function satisfy loss aversion? Does it satisfy diminishingsensitivity?Suppose that Joanna has linear probability weights (that is, she does NOT have prospecttheory’s non-linear probability weighting function). Hence, if she has a fifty-fifty chance ofgetting amounts m and m′, and her reference point is r, her expected utility is1/2v(m − r) + 1/2v(m′− r) (2)For parts (c), (d), and (e), assume that Joanna’s reference point is $0 (that is, no winsor losses) and answer the following questions for each part: (i) What is the g for whichJoanna would be indifferent between not gambling and taking fifty-fifty win $g or lose$4 gamble? (ii) Does this reflect…

An individual is faced with a choice of buying housing in one of two markets; the private market where he may buy any amount of housing he pleases at the going price, and the public housing market where he will be offered, on a take-it-or-leave-it-basis, a particular amount of housing at a price lower than that which he would pay for it on the private market. Will he necessarily choose the public housing? If so, may we conclude that he will consume more housing than he would have purchased had he been forced to buy it on the private market? (With thanks to Dr Leslie Rosenthal.)  

Draw a utility function (with income on the horizontal axis) for an individual who is risk-loving at low levels of income, risk-neutral at moderate levels of income, and risk-averse at high levels of income (with each of these three regions clearly labeled). How would someone who looked at this graph (and had no other information about the individual) be able to figure out the individual’s attitude toward risk (averse/loving/neutral) in each region?

Q12. Consider a utility function: U (F,C) = FC so MU_F = C and MU_C = F.Suppose as Case X, Total income is $100 and per unit prices of Food (F) and Cloth (C) are $2 and $15, respectively. a. What is the value of MRS at the optimal point and what does this value mean? b. What is the optimal consumption bundle i.e (F*,C*)? c. Plot the budget line and clearly depict the point of optimality in the F (x-axis)-C (y-axis) space.

1- A consumer who starts (i.e. has an endowment) at point B, and has preferences shown by IC1, will want to borrow.  Select one: True False   2-Assuming a mix of present and future consumption is preferred, ANY consumer who starts (i.e. has an endowment) at point A will gain utility from a rise in interest rates.    Select one:   True False   3-A consumer who starts at point B will want to borrow, but as little as possible in order to minimise the cost of interest.   Select one:   True False   4-If a consumer starts at point A, and then receives extra income in the present, this would appear as an outward shift of the budget constraint. Select one:   True False

A typical consumer has a well-behaved preference structure for his consumption bundle which includes only two goods, A and B.  assume that commodity A is normal and commodity B is inferior. By keeping commodity A on the x-axis and commodity B on the y-axis you are required to show the price decomposition for commodity B when $PB increases exogenously relative to $PA. Please Answer the question by using well labelled diagrams

Khan lives in a world with two consumption goods x and y. Her utility function is U (x, y) = √x² + y². a. If px = $3,py = $4, and her income, I, is equal to $50, what will be the quantities of x and y that Maya should buy to maximize her utility? Make sure that you write out the Lagrangian and the first-order conditions. (Hint: It may be easier to maximize U² than U). Have you found a true maximum? Explain your answer.

Mats, who has reference-dependent preferences over beer and money, goes to the local pub with a friend, but is not planning on drinking any beer or spending any of his 50 Euro in cash. Let his end-of-evening outcomes in pints of beer consumed and cash be c1 and c2, respectively, and let his reference point in pints of beer and cash be r1 and r2, respectively. Then, Mats’ utility is given by v(6c1 − 6r1) + v(c2 − r2), where v(x) = x for x ≥ 0, and v(x) = 1.5x for x < 0. (a)  Suppose that the price of beer is pB. Calculate Mats’ utility from drinking one pint of beer at this price. What is Mats’ utility from drinking no beer? And, comparing these two utility values, what is the maximum price pB that Mats would pay for one beer? (b)  Suppose that Mats unexpectedly gets a pint of beer as part of a promotion at the pub, and incorporates its consumption into his reference point in beer. [Hint: this means that (r1, r2) = (1, 50).] Suppose that Mats could sell the beer at a price pS.…

Answer both question (a) and (b) below. (a)  State theWeak Axiom of Revealed Preference (WARP). (b) In a two-good model, suppose a consumer always chooses the midpoint of the budget line given any (p1; p2; I), does the demand function satisfy WARP? Why? (HINT: Graphs can be helpful to answer the question.)
