A consumer is always indifferent between 2 Cokes and 1 Pepsi. Write out this consumer's utility function.

Expert Solution

He is indifferent between 2 Cokes and 1 Pepsi.

It means 1 pepsi gives him same utility as given by 2 cokes and they are perfect substitute. Therefore, Let C = Coke and P = Pepsi.

Then, utility function is given by:

U(C,P) = C + 2P

( Verification of function:

if he gets 2 cokes and 0 pepsi, then U(2,0) = 2

if he gets 1 pepsi and 0 coke, then U(0,1) = 2

Thus, he will be indifferent between 2 cokes and 1 pepsi with the given utility function).

A consumer can choose between goods X and Y. The consumer's utility function is: U=5X2Y2 Use following notation, as we have in class: Price of X = PX, Price of Y = PY, Income = I, the Lagrange multiplier = λ If PX= 20, PY = 5, and I = 400, what is the optimal amount of X that will maximize the consumer's utility subject to these prices and income? what is the optimal amount of Y that will maximize...

Distinguish between “cardinal” and “ordinal” measurement of utility as used in consumer theory. (b). Assume a consumer spends all her income in the purchase of two goods – Good X and Good Y whose prices are Ksh. 30 and Ksh. 20 per unit respectively. The consumer's monthly income is Ksh 3,000. She is satisfied with various combinations of X and Y but prefers to spend her income not in equal proportions – that is in a ratio of 1:1 respectively...

Consumer A regards the two goods as perfect complements, always wanting 2 units of good 1 for every unit of good s, where as B regards 4 units of good s and 3 units of good 2 as perfect substitutes. Initially, A has 60 units of good 1 and 75 units of good 2, and B has 140 units of good 1 and 25 units of good 2. a) Draw an Edgeworth box (put good 1 on the horizontal axis)...
