Information for questions 16-19 The following figure which shows Bobby’s indifference curves for juice and snacks. Also shown are budget lines resulting from different prices for snacks. Bobby has $20 to spend on these two goods. The price of juice is kept constant throughout this question group. As the price of snacks rises,

Information for questions 7-9 The figure below shows supply and demand for a certain good. Note the axes’ scales: on the horizontal axis, the quantity Q has grid spacing of 5 units of the good; on the vertical axis, the price P has grid spacing of $0.25. Adhere to the following convention, which is necessary to get exact answers: if a line (the supply curve or the demand curve) seems to cross an intersection of the grid, then by convention assume that it does so exactly. For example, the tip of the supply line seems to be at P=3.5, Q=70, so we’ll assume that it crosses the grid at exactly that point, that is, that when the price P=3.5, then the supply is Q=70, exactly. All answers are positive numbers. Only exact answers are accepted, so please make sure to check and doublecheck your reasoning and your calculations. If the answer cannot be obtained with the information given, enter the number 0. The government imposes a sales tax on this good of $1.25 per unit sold. Calculate the government revenue, when the tax is in place.

Information for questions 10-15 The figure below shows indifference curves for a consumer who consumes good X (on the horizontal axis) and good Y (on the vertical axis). The utilities of the indifference curves are 100, 200, 300, 400, and 500 (it’s up to you to determine which indifference curve corresponds to which utility). Note: the answers to the questions in this group won’t be exact. To have exact answers, we’d need an exact utility function and take derivatives. Since all we have are graphs, the answers will necessarily be approximate. The point is to make the best approximations that you can, using the limited graphical information. To see the figure as clearly as you can, try to have it on a computer screen and enlarge it; also, use a ruler. Enter all answers as positive numbers. Your answer must be within the approximation specified in each question. If the answer cannot be obtained from the figure, even as an approximation, enter 0. Starting at the same point, X=4 and Y=15, how much is her marginal utility with respect to Y? Your answer must be within 5 units of the best approximation possible from the figure.

Calculate the consumer surplus, when the tax is in place.

Information for questions 2-8 The figure below shows supply and demand for a certain good. On the horizontal axis, the quantity Q has grid spacing of 10 units of the good. On the vertical axis, each grid spacing represents $0.5.  Adhere to the following convention, which is necessary to get exact answers: if a line (the supply curve or the demand curve) seems to cross an intersection of the grid, then by convention assume that it does. For example, the tip of the supply line seems to be at P=5, Q=160, so we’ll assume that it crosses the grid at exactly that point, that is, that when the price P=5, then the supply is Q=160, exactly. All answers are positive numbers, except (possibly) the answer to question 7. Only exact answers are accepted, so please make sure to check and doublecheck your reasoning and your calculations. If the answer cannot be obtained with the information given, enter the number 0. The government imposes a sales tax on this good of $1.50 per unit sold. Enter the (after-tax) price that consumers pay per unit bought.

Information for questions 10-15 The figure below shows indifference curves for a consumer who consumes good X (on the horizontal axis) and good Y (on the vertical axis).

To see the figure as clearly as you can, try to have it on a computer screen and enlarge it; also, use a ruler. Enter all answers as positive numbers. Your answer must be within the approximation specified in each question. If the answer cannot be obtained from the figure, even as an approximation, enter 0. If the consumer is consuming 10 units of X and 10 units of Y, how much is her marginal rate of substitution? Your answer must be within 0.3 of the best approximation possible from the figure.

Information for questions 17-23 The figure shows two of Zhang’s indifference curves, in green. Zhang’s income is $240. The price of good Y is kept constant throughout this problem, at $40. The price of good X goes up from $30 to $120. Four straight lines (the two solid blue and the two dashed blue lines) are shown, which should be helpful in this problem. Four consumption points, A, B, C, and D, are also shown as dots, and labeled for the units of good X and good Y that they represent. For example, A=(2.4,5) means “consumption point A, with 2.4 units of X and 5 units of Y,” and analogously for all other points shown. All four points are points of tangency between one indifference curve and one of the straight lines. Only exact answer is accepted, so make sure to double check your reasoning and calculations. Enter 0 if the answer cannot be obtained from the information given. Note: to get exact answers, don’t read anything off the scale of the figure. Rather, just take the point labels as given. When the price of good X goes up from $30 to $120, how much of the change in Zhang’s consumption of good X can be attributed to the substitution effect? If the part of the change attributable to the substitution effect is an increase of her consumption of good X, enter it as a positive number, and if it is a decrease enter it as a negative number.

If the answer cannot be obtained with the information given, enter the number 0. The government imposes a sales tax on this good of $1.50 per unit sold. Calculate the change in consumer surplus due to the tax, that is, calculate the number: CSAT – CSBT, where CSAT is the consumer surplus after the tax is imposed, and CSBT, is the consumer surplus before the tax is imposed. This number can be positive, if the consumers gained with the tax, and negative, if consumers lost with the tax. You must enter the number with the right sign.
