4. consider the following utility functions
a) for each of these utility function what is the equation of an indifference curve ?
c) for each utility function show weather the function exhibits the diminishing rate of substitution property
d) do the above utility function represent the same preference ordering? why or why not?
Equation of IC is found by writing X2 as a function of X1, for a given constant utility level
D) if MRS is same, then two utility function will exhibit same preferences. Thus all consumers will rank the difference consumption bundles in same way
Bcoz each utility function is strict monotonic transformation of one other

Suppose Peter has $800,000 to spend on a house and “other goods” (denominated in dollars). The price of 1 square foot of housing is $300, and Peter chooses to purchase a house of 2,000 square feet in size. Assume that houses do not differ in quality: their price is solely determined by their size. Also, assume throughout that Peter spends money on housing solely for its consumption value, not as part of his investment strategy, and that Peter has well-behaved,...
1. Consider the following utility functions (a) For each of these utility functions: i. Find the marginal utility of each good. Are the preferences mono- tone? ii. Find the marginal rate of substitution (MRS) iii. Define an indifference curve. Show that each indifference curve (for some positive level of utility) is decreasing and convex. (b) For the utility function u2(x1, x2), can you find another utility function that represents the same preferences? Find the relevant monotone trans formation f(u) (c)...
For each of these utility functions,
b. Compute the MRS.
c. Do these tastes have diminishing marginal rates of
substitution? Are they convex?
d. Construct an indifference curve for each of these functions
for utility numbers U1 = 10 , U2 = 100 , U3 = 200 .
e. Do these utility functions represent different preference
orderings?
1. Consider the following utility functions: (i) U(x,y)- 6xy, (ii) U(x,y)=(1/5)xy, MU,--y and MU,--x ii) U(x,y)-(2xy)M 8xy2 and MUy -8x2y MU,-6y and...
Could someone help with this chart
The table below contains seven utility functions. For each utility function please compute the marginal utility with respect to X, and the marginal utility with respect to Xz. Use your expressions for the marginal utilities to find the marginal rate of substitution (MRS = Make sure you simplify the expression. Finally, state the level of utility for the consumption bundle (5,8) rounded to 1 d. You are not required to show your work in...
Brian works in a factory and spends his monthly income on Beer and Pizza. The utility function U(X,Y) = X0.5y0.5 represents Brian's preference. Here, X is the quantity of beer, and Y is the quantity of pizza. Assume the numbers of beer and pizza do not need to be integers. Brian's monthly income is $100, the price of pizza is $4, and the price of beer is $2. a) Find the optimal consumption bundle for Brian. (Bundle A) b) The...
Suppose Alex’s preferences are represented by u(x1,x2) = x1x32. The marginal utilities for this utility function are MU1 = x23 and MU2 = 3x1x22. (a) Show that Alex’s utility function belongs to a class of functions that are known to be well-behaved and strictly convex. (b) Find the MRS. [Note: find the MRS for the original utility function, not some monotonic transformation of it.] (c) Write down the tangency condition needed to find an optimal consumption bundle for well-behaved preferences....
QUESTION; Given Biwei’s utility function U=4XY, where X is consumption of beer and Y is consumption of pizza. For this utility function, the marginal utility of X is MUx = 4Y; the marginal utility of Y is MUY = 4X. 1) Suppose Y = 3. Calculate Biwei’s utility for X = 2, 3, 10, and 11. For a given level of Y, does good X display diminishing marginal utility? 2) Suppose X = 3. Calculate Biwei’s utility for Y =...
how
did they get MRS= -x2/x1?
Consider the utility function u ( 2 2) = Inc. +Inc. Suppose that the initial situation s given by Pi = 1, P2 = 2 and m = 100. Note that MU = 1 and MU2 = a) Find the consumer's optimal consumption bundle (0,2) and his utility at this consumption bundle. Solution: The budget line is 2.02 = 100 - 21 (1) Since the optimal bundle is an interior point, the tangency condition...
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...
1. Write down the equation of a utility function and draw an indifference curve that corresponds to each of the following cases. (a) Carol is always willing to give up 2 pizzas in exchange for 1 additional beer no matter how many pizzas and beers she has in her consumption bundle. (b) Bob always consumes beer and pizza in fixed proportions. Specifically, if Bob has 1 pizza, he consumes precisely 2 beers and additional beers represent no additional utility for...
