Infоrmаtiоn fоr questions 6-11 There аre only two goods, good X, аnd good Y, whose quantities are represented on the figure below as the x-axis and y-axis, respectively. Grid spacing: both the horizontal grid spacing and the vertical grid spacing are 50 units, of good X and good Y, respectively. The figure shows some of Charles’s indifference curves in those two goods. Also shown are several straight lines that you can use as budget constraints, as needed. It’s for you to decide which line or lines to use as budget constraints, given the information in this question group, and the need of each question. Except where noted, only the exact answers are accepted, so make sure to double- and triple-check your reasoning and calculations. To get exact answers, assume: (1) The tangency points between indifference curves and the straight lines (the black dots) lie exactly at grid intersections. For example, the lowest tangency point shown lies exactly at Qx=400, Qy=50. (2) If a line seems to cross a grid point, assume that it does so exactly. For example, the highest indifference curve shown crosses the consumption point Qx=450, Qy=700, exactly. Enter 0, if the answer cannot be obtained with the information given. For this question and the next, suppose that Charles’s income is I=2000, and that the price of good X is fixed at Px=2. The price of good Y goes down to a half, from Py=4, to Py=2. When the price of good Y goes down from $4 to $2, how much of the change in Charles’s consumption of good Y can be attributed to the substitution effect? If the part of the change attributable to the substitution effect is an increase of his consumption of good Y, enter it as a positive number, and if it is a decrease enter it as a negative number.
