Deadweight loss is the loss in social surplus that results from producing more or less than the efficient quantity. We found that social surplus is maximized at an output of three ventilators, with a social surplus of $140,000. We also found that if only one ventilator is produced, the social surplus is $80,000. The difference between these two represents the deadweight loss and is equal to $140,000−$80,000=$60,000.
60,000

Consider a perfectly competitive market as shown in the given graph. Suppose the initial price of a product is $1.40 per unit. At this price, the marginal revenue (MR) curve faced by a firm is ▼ . If the market price increases from $1.40 to $2.70 per unit, the firm would ▼ decrease increase production from enter your response here to enter your response here units. If the market price decreases from $1.40 to $0.80 per unit, the firm would produce enter your response here units because at this price ▼ MR 2 equals MCMR2=MCMR 1 equals MR 2MR1=MR2MR 2 equals MR 3MR2=MR3MR 1 equals MCMR1=MC.
MR 1, If the market price increases from $1.40 to $2.70 per unit, the firm would increase production from 272272 to 350350 units. If the market price decreases from $1.40 to $0.80 per unit, the firm would produce 200200 units because at this price MR 2 equals MCMR2=MC. The firm expands production until MR=MC. MR equals price in a perfectly competitive market. Therefore, by linking the market price to the MC curve, we can determine how a competitive firm changes its output in the short run when the market price changes. At the initial market price of $1.40 per unit, the MR curve faced by a firm is MR1. Therefore, the firm equates MR1 and MC and, produces 272 units. If the market price increases from $1.40 to $2.70 per unit, the MR curve faced by a firm changes to MR3 Subscript . Therefore, the firm equates MR3 and MC and, produces 350 units. Similarly, at the market price of $0.80 per unit, the firm equates MR2 and MC and produces 200 units. We can trace out the firm's supply curve by completing this exercise for various price levels.
The graph on the right depicts the supply and demand curves for a market in competitive equilibrium. Part 3 1.) Using the triangle drawing tool, highlight the area on the graph that represents producer surplus. Label this area 'PS'. Using your graph, calculate the producer surplus in this market. Producer surplus is enter your response here. (Round your response to two decimal places.)
PS Graph producer surplus triangle: 4.50 (1/2x base(3-0) x height (6-3)) 1/2 *base*height
Consider the adjacent graph. When the market price (Pmarket) is $2.50, the total producer surplus equals $enter your response here. If the equilibrium market price (Pmarket) changes to $2, the total producer surplus would ▼ increase decreaseremain the same.
The producer surplus is the area above the MC curve and below the equilibrium price line. When we have linear supply curves, a mathematical formula can be used to compute the producer surplus. If the equilibrium market price is $2.50 per unit, then we compute the producer surplus as the base of the triangle multiplied by the height of the triangle multiplied by 1/2: Producer surplus=1/2×(Base of triangle×Height of triangle) = 0.5×(500×$1)=$250. This means that total producer surplus is $250 in this market. There are several ways in which producer surplus can increase or decrease. For example, at a lower equilibrium market price ($2), the producer surplus decreases because the area above the supply curve and below the equilibrium price line gets smaller. Consider the adjacent graph. When the market price (Pmarket) is $2.50, the total producer surplus equals $250. If the equilibrium market price (Pmarket) changes to $2, the total producer surplus would decrease.

Consider the given graph that shows the price and the quantity demanded and supplied of good X in a competitive market. The price that equates the quantity supplied and the quantity demanded of good X is $40. The quantity that corresponds to the competitive equilibrium price is 3000 units of good X. Part 2 In the graph, at the market price of $60, the market is not in a competitive equilibrium. At this price, the excess supply equals 1000 units of good X. Part 3 In the graph, at the market price of $20, the quantity demanded is greater than the quantity supplied by 2000 units of good X. The competitive process will eventually push up the market price to $40. As a result, the market will be in competitive equilibrium.

Larry Krovitz is a salesman who works at a used-car showroom in Sydney, Australia. It's the last week of July, but he is yet to meet his sales target for the month. A customer, Harold Kumar, who wants to buy a Ford Fiesta, walks into the showroom. After taking one of the cars for a test drive, Harold decides to buy it. While $11,000 was the least that Larry would have been willing to accept for that car, he quotes a price of $17,000. After some bargaining, the car is sold for $16,000. In this case, the producer surplus is $5,000 If the cost of the car to Larry is $11,000, his profit is $5,000

Consumer surplus is measured by the area under the demand curve and above the equilibrium price line. Consumer surplus is measured by the area under the demand curve and above the equilibrium price line. In the graph on the right, this is the area shaded in green. The area is found using: 12×(Base of triangle×Height of triangle) For the values shown, we get: CS = 12×(90×(70−50)) = $900 Producer surplus is measured by the area above the supply curve and under the equilibrium price line. Producer surplus is $0 Producer surplus is measured by the area above the supply curve and under the equilibrium price line. In the graph on the right, this is the area shaded in pink. The area is found using: 12×(Base of triangle×Height of triangle) For the values shown, we get: PS = 12×(90×(50−20)) = $1,350 The social surplus is the sum of consumer and producer surplus. It is the area that lies between the demand and supply curves from 0 to the equilibrium quantity. Social surplus is measured by the area that lies between the demand and supply curves from 0 to the equilibrium quantity. In the graph on the right, this is the area shaded in gray. The area is found using the following formula twice: 12×(Base of triangle×Height of triangle) Alternatively, given the prior calculations of consumer and producer surplus, these two only need to be summed: SS = CS + PS = $900 + $1,350 = $

There are four hospitals (consumers in this example) willing to pay the following amounts for a ventilator: Hospital W Hospital X Hospital Y Hospital Z $90,000 $50,000 $25,000 $60,000 There are producers that can produce at most one ventilator each and at the following costs: Producer A Producer B Producer C Producer D $20,000 $30,000 $60,000 $10,000 What is the most surplus that can be realized if only one ventilator can be produced? Which firm should produce it, and which hospital should consume it? If only one ventilator can be produced, it should be made by Producer ▼ ABCD and consumed by Hospital ▼ WXYZ, resulting in a maximum surplus of $enter your response here. (Enter your answer as a whole number.)
If only one ventilator can be produced, it should be made by Producer D and consumed by Hospital W , resulting in a maximum surplus of $80,000 If only one ventilator can be produced, it should be made by the company that can produce it most efficiently, at the lowest cost. It should be purchased by the hospital that values it most and has the highest reservation price. This means Producer D should make the ventilator and the ventilator should be purchased by Hospital W. The most surplus that could arise from this is the difference between the reservation price of the hospital and the reservation price (marginal cost) of the producer. The most surplus is $90,000−$10,000=$80,000. The highest possible surplus that can be realized in this market occurs when those who produce ventilators most efficiently sell to those hospitals who value the ventilators most. This means Producer D should sell to Hospital W, resulting in a surplus of $80,000. Producer A should then sell to Hospital Z, resulting in a surplus of $40,000, and Producer B should sell to Hospital X, resulting in a surplus of $20,000. Producer C will not sell to Hospital Y, since the price it charges is greater than the reservation price of the hospital. Thus, we see three ventilators should be produced and sold with Hospitals W, X, and Z purchasing the ventilators and Producers A, B, and D making them. The social surplus is the sum of the surpluses from each transaction. Social surplus is $140,000.
Given the supply and demand curves on the right, when the price of the good is $20, we say that the market is in competitive equilibrium. At this price, we know that the quantity supplied is equal to the quantity demanded. Part 2 Using the graph on the right, illustrate the impact of an increase in the price of the good from $20 per unit to $30 per unit, assuming everything else in the economy remains the same. Part 3 1.) Using the point drawing tool, place a point at the quantity supplied when the price is $30 per unit. Label this point 'A'. 2.) Using the point drawing tool, place a point at the quantity demanded when the price is $30 per unit. Label this point 'B'. If the only change in the market was that the price increased to $30, then we know that the quantity supplied will be greater than the quantity demanded, resulting in an excess supply, which is also k
