Kevin's Fire Engines is the sole seller of fire engines in the fictional country of Pyrotania. Initially, Kevin produced eight fire engines, but he is considering increasing production to nine fire engines. The following graph shows the demand curve Kevin faces. As you can see, to sell the additional engine, Kevin must lower his price from $100,000 to $80,000 per fire engine. Note that although Kevin would gain revenue from the additional engine he sells, he would also lose revenue from the initial eight engines because he would have to sell them all at the lovwer price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial eight engines by selling at $80,000 rather than $100,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $80,000. 200 180 Revenue Lost 160 140 120 Revenue Gained Demand 100 80 60 40 20 1 2 3 4 5 6 10 QUANTITY (Fire engines) increase production from 8 to 9 fire engines, because the dominates in this scenario. Kevin True or False: If Kevin's Fire Engines were a competitive firm instead and $100,000 were the market price for an engine, increasing its production would not affect the price at which it can sell engines.

Asim's HookNLadder is the only company selling fire engines in the fictional country of Alexandrina. Asim initially produced eight trucks, but then decided to increase production to nine trucks. The following graph gives the demand curve faced by Asim's HookNLadder. As the graph shows, in order to sell the additional fire truck, Asim must lower the price from $80,000 to $40,000 per truck. Notice that Asim gains revenue from the sale of the additional engine, but at the same time, he loses revenue from the initial eight engines because they are all sold at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial eight engines by selling at $40,000 rather than $80,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $40,000.

Tim True increase production from 4 to 5 fire engines because the True or False: If Tim's Fire Engines were a competitive firm instead and $105,000 were the market price for an engine, increasing its production would not affect the price at which he can sell engines. False dominates in this scenario.

Jabari's HookNLadder is the only company selling fire engines in the fictional country of Alexandrina. Jabari initially produced five trucks, but then decided to increase production to six trucks. The following graph gives the demand curve faced by Jabari's HookNLadder. As the graph shows, in order to sell the additional fire truck, Jabari must lower the price from $160,000 to $120,000 per truck. Notice that Jabari gains revenue from the sale of the additional engine, but at the same time, he loses revenue from the initial five engines because they are all sold at the lower price.

Imagine that you run the toll authority for a city bridge. You must charge all of your customers the exact same toll. Initially, you have set the price at $7 per trip. The blue line on the following graph shows the daily demand curve for trips across the city bridge. On the following graph, use the purple rectangle (diamond symbols) to shade the area representing the total daily revenue when the toll is $7 on the graph. Notice that when you click on the rectangle, the area is displayed. TOLL (Dollars per vehicle) 10 9 8 7 4 2 1 0 0 Demand 10 20 30 40 50 60 70 80 QUANTITY (Thousands of vehicles per day) 90 When the toll is $7, total revenue is $ 100 TR at $7 TR at $8 An advisor has suggested that if you raise the toll to $8, the toll authority would bring in more revenue. To analyze this, use the green rectangle (triangle symbols) to shade the area representing the total daily revenue when the toll is $8 on the graph. thousand per day, but when the toll is $8, total revenue is $ Based…

Consider two markets: the market for motorcycles and the market for pancakes. The initial equilibrium for both markets is the same, the equilibrium price is $4.50, and the equilibrium quantity is 29.0. When the price is $7.75, the quantity supplied of motorcycles is 65.0 and the quantity supplied of pancakes is 103.0. For simplicity of analysis, the demand for both goods is the same. Using the midpoint formula, calculate the elasticity of supply for pancakes. Please round to two decimal places.

The linear demand curve for Pete's butternut squash and pecan pastry is Quantity = 205.5 12.78 x Price. What is the maximum Revenue (calculated as Price x Quantity) that Pete's can earn on this product, given the demand curve? (Rounding: penny.)

3. Consider the Smith family who have the following demand for rental housing (q, measured in square feet): q=0.5*(y/p), where y is the Smith family income and p is the price of housing per square foot. The Smith's income is $4000 per month and initially the price of housing is $2 per square foot per month. a. If the Smiths are operating on their demand curve, how much housing are they consuming? b. How much is the Smith family's monthly rent? How much does the Smith family spend on other consumption? c. Starting from the initial equilibrium, the government now grants the Smiths a proportional rent subsidy with B=0.5. How much housing does the Smith family purchase given the subsidy? d. What is the gross market rent per month paid by the Smith family? What is the net rent (after deducting the subsidy) paid by the Smith family? How much does the Smith family spend on other consumption in its new equilibrium? e. What is total dollar outlay of the government for the Smith's housing…

Suppose the market for sourdough is perfectly competitive, so sellers take the market price as given. Darnell manages a restaurant that offers sourdough for sale. The following graph plots Darnell's weekly supply curve (orange line). Point A represents a point along his supply curve. The price of sourdough is $2.25 per slice, which is given by the black horizontal line. PRICE (Dollars per slice) 9.00 8.25 7.50 6.75 6.00 5.25 4.50 3.75 3.00 2.25 1.50 0.75 Price Supply 0 2 4 XXX Darnell's Weekly Supply 6 A 8 10 12 14 16 18 QUANTITY (Slices of sourdough) 20 22 24 ?
