4. Randy and Esther consume only eggplant (I1) and zucchini (T2). Randy has utility function UR = I? x and Esther has utility function U E = $15 + 125 . Randy is endowed with 6 eggplant ($1) and 3 zucchini (12) and Esther is endowed with 6 eggplant (371) and 3 zucchini (172). (a) Draw an Edgeworth box with I] on the horizontal axis and $2 on the vertical axis. Position Randy on the bottom left corner and Esther on the top right corner. Indicate the total number of units of .171 and 332. La be] the endowment allocation. Show Randy's and Esther's indifference curves. (b) In your previous graph. draw the contract curve rst. Then. express the contract curve in an equation. (c) In your previous graph. indicate the segment of contract curve they would voluntarily exchange towards. Explain. {d} Set 11 as the numeraire, i.e.1 assume p1 = 1 and p2 = p. State the equi librium budget constraint. Is there more than one equilibrium budget constraint? Find the competitive equilibrium allocation in terms of p
