Information for questions 2-6 Demand for travel guides to the Ozarks is given by

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. 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.

Calculate the government revenue received from this tax.

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.

Information for questions 9-16 Demand and supply are given by the two equations: QD = 100 – 20 P and QS = 80 P, respectively. Here, QD is quantity demanded, QS is quantity supplied, and P is the price. Suggestion: draw a neat figure with these two curves, and make the figure roughly on scale. Use the figure just to keep track of the numbers that you calculate, don’t read any answers off the figure. Only the exact answer is accepted, so make sure to doublecheck your calculations. Enter 0 if the answer cannot be determined from the information given. Calculate the price in equilibrium.

From the information given, which of the following points do we know will be on Zhang’s demand curve for good X? Here, PX is the price of good X, and QX is the quantity of good X.

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 producer surplus, when the tax is in place.

There are only 3 consumers in a market, Angel, Berry, and Cameron. Their demands for a certain good are given by QA=100–2P, QB=200–4P, and QC=50–P, respectively. Enter the equation for the market demand in the blank below. To be graded correctly, your answer must be exactly in the format “Q=M-NP”, where M and N are whole numbers for you to calculate and enter in place of M and N. Note that there are no spaces, and Q and P are in capitals. So, for example, answer “Q=26-4P” would be accepted (if the numbers 26 and 4 were the correct ones), but answers “Q = 26 – 4P” would not be accepted (it has spaces), nor would answer “q=26-4p” (did not capitalize q and p).

If the part of the change attributable to the income 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.
