The following questions refer to the graph of a monopolist shown below The figure shows a graph with a horizontal axis labeled Quantity, a vertical axis labeled Price, and an origin labeled zero. Four quantities appear on the horizontal axis and are labeled, from left to right, Q sub one, Q sub 2, Q sub 3, and Q sub 4. Five prices appear on the vertical axis and are labeled, from bottom to top, P sub one, P sub 2, P sub 3, P sub 4, and P sub 5. There are two downward-sloping straight lines, two curves, and six points on the graph. The leftmost downward-sloping line is labeled Marginal Revenue and begins near the top of the vertical axis, above P sub 5, and moves down and to the right, passes through a point labeled V at Q sub one and P sub one, then passes through the horizontal axis at Q sub 2, and ends below the horizontal axis. The rightmost downward-sloping line is labeled Demand and begins at the same point on the vertical axis as the Marginal Revenue line, moves down and to the right, passes through a point labeled R at Q sub 1 and P sub 5, then passes through a point labeled S at Q sub 2 and P sub 4, then passes through a point labeled T at Q sub 3 and P sub 3, then passes through a point labeled U at Q sub 4 and P sub 2, continues on, and ends in the right side of the graph, above the horizontal axis and to the right of Q sub 4. The two curves begin above the horizontal axis and to the right of the vertical axis. The curve labeled Marginal Cost begins to the left of Q sub one and below P sub one, curves up and to the right, intersects the curve labeled Average Total Cost and the Marginal Revenue line at point V, continues up and to the right, intersects the Demand line at point T, and continues on. The Average Total Cost curve begins to the left of the start of the Marginal Cost curve, close to P sub 3, curves down and to the right, intersects the Marginal Cost curve and Marginal Revenue line at point V, then curves up and to the right, intersects the Demand line at point U, and ends to the right of and below the Marginal Cost curve. A point labeled W is at Q sub one and P sub 2. If the government regulates the monopolist to set price equal to average total cost, it will establish the price at

The provided graph shows the marginal private cost (MPC) curve, the marginal social cost (MSC) curve, the marginal private benefit (MPB) curve, and the marginal social benefit (MSB) curve in the market for electric vehicles. This graph shows the market for electric vehicles, with price on the vertical axis ranging from $7 to $20, and quantity on the horizontal axis from 0 to 60. The graph includes a downward-sloping marginal private benefit (MPB) curve and a higher, downward-sloping marginal social benefit (MSB) curve. An upward-sloping marginal private cost curve, labeled MPC equals MSC, represents the marginal cost to society and private producers. Horizontal dashed lines indicate price levels at $7, $10, $13, $16, and $19, while vertical dashed lines show quantities at 21, 30, and 39. The graph illustrates the difference between private and social benefits and the socially optimal level of electric vehicle production. Use the graph to answer questions a-e. Does the graph show a negative consumption externality or a positive consumption externality? Explain. (3 points) Identify the socially optimal quantity of electric vehicles. (3 points) What is the dollar value of the marginal external benefit? (3 points) Calculate the deadweight loss in the market for electric vehicles at the market equilibrium. Show your work. (3 points) The government wants the socially optimal quantity of electric vehicles to be produced and consumed. Would the government implement a per-unit tax on producers, a lump-sum subsidy to producers, a per-unit subsidy to consumers, or a lump-sum tax on consumers? Explain. (3 points)

The figure presents a graph in the first quadrant of a coordinate plane. The horizontal axis is labeled Quantity, in units, and the numbers 0 through 400, in increments of 100, are indicated. Vertical grid lines emanate upward from the values 100 and 200 on the horizontal axis. The vertical axis is labeled Price, in U S dollars, and the numbers 2 through 12, in increments of 2, are indicated. Horizontal grid lines emanate to the right from the values 4, 6, and 8 on the vertical axis. The graph has two curves that are labeled Demand and Supply. The Demand curve begins at 10 on the vertical axis, and moves downward and to the right in a straight line. It passes through the points with coordinates 100 comma 8 and 200 comma 6, and ends approximately at the coordinates 400 comma 2. The Supply curve begins at 2 on the vertical axis, and moves upward and to the right in a straight line. It passes through the point with coordinates 100 comma 4, intersects the Demand curve at the coordinates 200 comma 6, and ends approximately at the coordinates 400 comma 10. There are three unlabeled points indicated on the graph. The first point is located on the Demand curve at the coordinates 100 comma 8. The second point is located on the Supply curve at the coordinates 100 comma 4. The third point in located at the intersection of the Demand and Supply curves at the coordinates 200 comma 6. Assume that the government imposes a $4 per-unit tax on sellers of a good in the market described by the graph above.What are the price paid by buyers, the after-tax price received by sellers, and the deadweight loss?

The following table shows the total benefit, in dollars, that Carlos receives from consuming two goods, sodas and candy bars. Table: Carlos’s Total Benefit Schedule for Sodas and Candy Bars Quantity of Sodas Total Benefit of Sodas Quantity of Candy Bars Total Benefit of Candy Bars 0 $0 0 $0 1 $40 1 $80 2 $70 2 $120 3 $90 3 $140 4 $100 4 $152 5 $103 5 $156 6 $105 6 $156   Carlos has a limited weekly income of $20, and he spends it all on candy bars and soda. Assume the price of each soda is $2 and each candy bar is $4. Identify the quantity of candy bars and sodas that will maximize Carlos’s total benefit given his weekly income. Explain using marginal analysis. (3 points) Calculate the consumer surplus from the fourth candy bar. Show your work. (3 points) If Carlos’s weekly income decreases from $20 to $18, would Carlos be able to buy 5 sodas and 2 candy bars? Explain your answer. (3 points) Suppose that candy bars are produced in a perfectly competitive market, and the price of sugar, an input for producing candy bars, increases. If candy bars are a normal good, will the quantity of candy bars that will maximize Carlos’s total benefit increase, decrease, or stay the same? Explain. (3 points) Now suppose that instead the price of sodas increased by 10% and Carlos buys 6% fewer sodas and 3% less of Good B. Based on this change, state whether sodas and Good B are substitutes, complements, inferior, or normal goods. Explain using numbers. (3 points)
