Define externalities. If there is a negative externality at alocal, please propose on how to solve this problem.

What are commons and public goods? Provide any two examples of such goods.

what is an externality? give an example of a postiive externality and an example of negative externality

An effluent fee O is a reward to companies using production methods that create positive externalities. O is also called a pollution subsidy. O gives a firm the right to pollute if it pays a tax on what it discharges. O is intended influence the market by increasing supply and decreasing price.

Consider the market for steel. Suppose that a steel manufacturing plant dumps toxic waste into a nearby river, creating a negative externality for those living downstream from the plant. Producing an additional ton of steel imposes a constant external cost of $165 per ton. The following graph shows the demand (private value) curve and the supply (private cost) curve for steel. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $165 per ton. 1100 990 Social Cost 880 770 Supply (Private Cost) 660 550 440 330 220 Demand 110 (Private Value) 1 2 4 7 QUANTITY (Tons of steel) PRICE (Dollars per ton of steel)

The Coase Theorem says that if people negotiate the right perform activities that cause externalities, they can always arrive at efficient solutions to problems caused by externalities. Use an example to explain why the people that are harmed are willing to pay to stop pollution.

Which of the following is an example of an activity generating a positive externality? O A. You buy a new car and then find $5,000 in the door panel. OB. Your next-door neighbor mows the lawn at 6 am. C. Your next-door neighbor installs a bat house and the bats eat mosquitoes. D. After Joe buys health insurance, he decides to quit smoking.

Compared to a good with no externalities, a good with a negative externality will appear to have experienced a Increase in Supply ODecrease in Supply Olncrease in Demand i ODecrease in Demand i at each corresponding price.

What is externality?

Air pollution creates a negative externality—a cost suffered by a third party as a result of an economic transaction. A standard solution to a negative externality is a Pigouvian tax, a tax that raises the marginal private cost of pollution emissions to the level of the marginal social cost. The socially optimal quantity of pollution emissions is then determined by the intersection of the marginal private benefit, or demand, curve and the marginal social cost curve. The article notes that "putting a dollar value on the benefits of cleaner air has been difficult." Assuming this problem has been resolved, in the accompanying diagram, move the endpoints of line Smarginal social cost to show the marginal social cost curve. Then move the line labeled "Tax" to show the amount of the tax needed to limit emissions to the socially optimal level.
