A consumer is observed to purchase X1 = 20, X2 = 10 at prices P1 = 2, and P2 = 6. She is also observed to purchase X1 = 18, X2 = 4 at prices P1= 3, P2= 5. Is her behavior consistent with the axioms of the theory of revealed preference?

  • Luke's choice behavior can be represented by the utility function u(x1,x2)= x1 + x2

    Luke's choice behavior can be represented by the utility function u(x1,x2)= x1 +  x2.The prices of x1 and x2 are denoted as p1 and p2, and his income is m. 1. Draw at least three indifference curves and find its slope (i.e. MRS). Is the MRS changing depending on the points of (x1, x2) at which it is evaluated, or constant? 2. Draw a budget constraint assuming that p1 < P2. Find the optimal bundle (x1*,x2*) as a function of income and prices. 3....
