Suppose Philip’s utility function over two goods, 1 and 2, is given by the quasilinear form, U(q ,q )=2q0.5 +q. Let p1, p2, and Y denote the prices of the two goods and Philip’s income. In the first few parts of the problem, you will solve for Philip’s demand functions for the two goods.
(a) To start with, suppose the solution is interior and use the tangency condition, or equal marginal principle, to solve for q1∗ (and separately, q2∗) as a function of Y , p1 and p2.
(b) Next, given your expression for q2∗, what conditions on p1, p2, and Y are necessary for the point of tangency to be interior? (1 point)
(c) When that condition is not satisfied, what are the demands for the two goods?
(d) Next, using the demand functions you derived in the previous parts, draw Philip’s Engel curves for each of the two goods.

This question explores some features of the quasilinear utility function. Avi’s utility function is ?(?, ?) = 4?1/2 + ?. Barry’s utility function is ?(?, ?) = ? + 3?1/3. Derive Avi’s demand functions for goods x and y. What must be true of Px for her to be at a corner solution? Which good would not be consumed under this condition? (10 points) Now assume an interior solution and graph Avi’s income consumption curve. (3 points) Derive Barry’s demand...

how did they dervice that to get 1/x1=p1/p2
income goes entirely to the consumption of good 2. If quasilinear, we sometimes say that there is a "zero income e income doesn't Thus the Engel curve for good 1 is a vertical line the demand for good 1 remains constant. For example, let us calculate the demand functions for t as yo u(x1, 2)= In a1+x2. Applying the first-order condition gives P1 P2

Suppose that an individual has the following quasilinear utility function: ?(?1, ?2) = ln(?1) + ?2 Show graphically the total effect, substitution effect and income effect when the price of good ?1 decreases (assuming there is an interior solution). Then derive Hicksian demand curves for ?1.(the sign in the utility function is positive)

Suppose there are two firms in a market producing differentiated products. Both firms have MC=0. The demand for firm 1 and 2’s products are given by: q1(p1,p2) = 5 - 2p1 + p2 q2(p1,p2) = 5 - 2p2 + p1 a. First, suppose that the two firms compete in prices (i.e. Bertrand). Compute and graph each firm’s best response functions. What is the sign of the slope of the firms’ best-response functions? Are prices strategic substitutes or complements? b. Solve...
