Question

1. Alice enjoys consuming goods z and y. Where (x, y) is the consumption bundle and 0 < a < 1, Alices utility is: u(z, y) -zy- (a) Originally, Alice has income m 16, and faces prices p Py1, and consumes a bundle at which her utility (subject to her budget) is maximised. Then, py rises to 4. Alice is sadder with the new bundle she chooses, and tells you that her compensating variation is 16: that is, she would need an extra 16 dollars to be as happy at the new prices as she was at the old ones. Assuming Alice is telling you the truth, find a. b) Find Alices equivalent variation.

Is the answer to part (a) 2/3 or 1/2?

    Consider the following utility function of 3 goods, x, y and z: U(x,y,z)=ax+by+cz; x,y,z≥0 and a, b, c are constants. The prices of good x and y is denoted by pX and pY respectively. The income is denoted by m. Good z is provided by the government free of cost but the quantity of good z provided by the government depends on the consumption of good x and y chosen by the consumer. For example, if in equilibrium, the consumer...

    1. (24 total points) Suppose a consumer’s utility function is given by U(X,Y) = X1/2*Y1/2. Also, the consumer has $72 to spend, and the price of Good X, PX = $4. Let Good Y be a composite good whose price is PY = $1. So on the Y-axis, we are graphing the amount of money that the consumer has available to spend on all other goods for any given value of X. a) (2 points) How much X and Y...
