According to the above pictures, the market equilibrium price and quantity in the market with the positive externality is A. P6; Q4. B. P7; Q3. c. P3; Q2. D. P2; Q1.

The market for plasticans is perfectly competitive. Market Supply is givenby Q=4P and Market Demand is given by Q=368-2P. Each extra unit ofplastican produced creates a positive externality of $5. What is theefficient quantity? Efficient quantity is determined by setting Marginal Social Costs(=Marg. Pvt. Cost + Marg. External Cost.) equal to Marg. SocialCost=MWTP which is captured by the Demand curve

The restaurant industry develops an exciting new technology, a robot that quickly prepares food in half the usual time of chefs. This increases supply (producers save costs on labor) and demand (consumers find it fun to watch the robot make a meal) such that the price remains constant. However, the robot runs on coal and produces a lot of pollution, generating an external cost on production. How do consumer and producer surplus change as a result of this new technology? Choice 1 of 4:Consumer surplus increases but the change in producer surplus is indeterminateChoice 2 of 4:Producer surplus increases but the change in consumer surplus is indeterminateChoice 3 of 4:Both producer and consumer surplus increaseChoice 4 of 4:Both producer and consumer surplus decrease

Consider the market illustrated in the figure to the right. Supply curve S₁ represents the private cost of production and demand curve D₁ represents the private benefit from consumption. Suppose consumption of this good creates a positive externality. Show how the externality affects the market. 1.) Use the line drawing tool to draw either a new supply (S₂) or demand (D₂) curve incorporating the positive externality in consumption. Properly label this line. 2.) Use the point drawing tool to indicate the market equilibrium price and quantity. Label this point 'Market equilibrium'. 3.) Use the point drawing tool to indicate the efficient equilibrium price and quantity. Label this point 'Efficient equilibrium'. Carefully follow the instructions above, and only draw the required objects. Price Quantity S₁ D₁ N

Assume a perfectly competitive market with no externalities. The demand curve is P =52 - 0.06×Qd. The supply curve is P =0.06×Qs. In equilibrium, what is total surplus?

Finding an Efficient Solution, Supply: P = 10.0 + 0.1Q; Demand: P = 50.0 − 0.125Q. Let Marginal External Cost (MEC) = 0.05Q. Solve for Q and P
