Answer #1

1. 2.a) utility: u= 24x2 Budget: M = pike+ P222 Equilibrium : mul a pu a PI = P282 from budget: M = biza+bize = a piza uz to

Figure 1

X2 IE(x2) BH 1SE(x2) fIE(x1) 10 U=400 U=200 SE(xl) 20 30 X1

e)

The income effect is movement from B to C. Therefore,

IE(21) = 20 – 14.14 = 5.86

IE(22) = 20 – 14.14 = 5.86

    please in part b graph it with identifying everything. 2. Consumer Theory. Ahn's utility function for goods X (pizzas) and Y (cola) is represented as U(X, Y) = 2ln(X)+ln(Y). The prices of X and Y are $1 and $1, respectively. Ahn's income is $12. 1) Calculate Ahn's optimal consumption bundle (X*, Y*). (X*, Y*)= 2) Suppose there is an increase in the price of X. Illustrate the net effect, income effect, and substitution effect on Ahn's optimal consumption choice.
