2. Show that each of the following utility functions has a diminishing MRS. Do they exhibit constant, increasing, or decreasing marginal utility? Is the shape of the marginal utility function an indicator of the convexity of indifference curve? a. (2) U(X,Y) = XY b. (2) U(X,Y) = x2y2 c. (2) U(X,Y) = In X + In Y
Calculate the MRS for the following three utility functions: ·U(x,y) = xy . U(x,y) = lnx + lny . U(x, y) = x2y2 Is the result suprising? If yes, try to explain it.
Use the following table to indicate whether the marginal rate of substitution (MRS) of each utility function increases, decreases, or is constant as x increases. MRS Increases with Utility Function Ux,y)- 3x y U(x,y) = MRS Decreases with x Constant MRS MRS Increases withx x-y U(x,y) = For a utility function for two goods, U xy to have a strictly diminishing MRS ie, to be strictly quasi concave), the following condition must hold: Use the following table to indicate whether...
A) Let utility over 2 goods be defined as U(x,y)=x+xy+y. Find the MRS by implicitly solving for y (hint: set U=k) and calculate -dy/dx. B) Now find the MRS by using MRS =Ux/Uy.
3. Suppose the utility function for two goods, x and y, is: U = U(x,y) = xłyż. a. Graph the indifference curve for U = 10. b. If x = 5, what must y equal to be on the U = 10 indifference curve? What is the MRS at this point? c. Derive a general expression for the MRS for this utility function. Show how it can be interpreted as the ratio of the marginal utilities. d. Does this individual...
8.1. Consider a transformation of the utility function in Question 7 using In(u). In other words the new utility function u' = In(u) = In(xay!) = x In(x) + b × ln(y). What is MRSr.y of this new utility function? Is it the same as or different from MRS,y you found in Q7.3? Explain. 8.2.Will the MRS be still the same for each of the following transformation? Explain without directly solving for MRS. a), u, = u2 b). 1/ =...
5. Consider the utility function U(x, y) = 2/x + y. 1) Is the assumption that "more is better” satisfied for both goods? 2) What is MRS, for this utility function? 3) Is the marginal rate of substitution diminishing, constant, or increasing in x as the consumer substitutes x for y along an indifference curve? 4) Will the indifference curve corresponding to this utility function be convex to the origin, concave to the origin, or straight lines? Explain.
Consider the utility function U(x,y) = 3x+y, with MUx=3 and MUy=1 a) Is the assumption that more is better satisfied for both goods b) Does the marginal utility of x diminish, remain constant, or increase as the consumer buys more x? Explain. c)What is MRS x,y? d) Is MRS x,y diminishing, constant, or increasing as the consumer substitutes x for y along an indifference curve? e) On a graph with x on the horizontal axis and y on the vertical...

Problem 1 (10pts) Jim's utility function is U (x, y) = xy. Jerry's utility function is U (x,y) = 1,000xy +2,000. Tammy's utility function is U2, y) = xy(1 - xy). Bob's utility function is U(x,y) = -1/(10+ 2xy). Mark's utility function is U (2,y) = x(y + 1,000). Pat's utility function is U (2,y) = 0.5cy - 10,000. Billy's utility function is U (x,y) = x/y. Francis' utility function is U (x,y) = -ry. a. Who has the same...
