raffic Lights in Plymouth) Look at the figure Traffic Lights in Plymouth. Plymouth has 1,000 residents. Each of the residents has the same individual marginal benefit per traffle light. If the government provides traffic lights, the socially efficient quantity is:

Only typed answer  You are an industry analyst that specializes in an industry where the market inverse demand is P = 100 - 3Q. The external marginal cost of producing the product is MCExternal = 6Q, and the internal cost is MCInternal = 14Q.   Instruction: Round your answers to the nearest two decimal places.   a. What is the socially efficient level of output?   units     b. Given these costs and market demand, how much output would a competitive industry produce?   units     c.

If it costs $6 to purchase & plant a tree, what is the socially optimal number of trees to be purchased? answer: [x] trees

Suppose Troutsville (population of 4) wants to put on a firework display. Leslie would get $40 worth of benefit, Mark would get $30 worth of benefit, Maggie would get $20 worth, and Erika would get $10 worth. What is the socially efficient amount to spend on the display? a. $25, the average of their benefitsb. $10, the minimum of their benefitsc. $40, the max of their benefitsd. impossible to telle. $100, the sum of their benefits

Please help with the calculations & working :) In this question there is a diagram with ‘y’ being the vertical axis representing costs/damages, and ‘P’ being a horizontal axis representing pollution. Abatement is the opposite of pollution, so if pollution falls from, say, 3 to 1 abatement rises by 2. 1. Suppose the marginal damage curve to private firms is MDP: y=0 and the marginal cost of abatement is MCA: y=1-P if P<1 and y=0 otherwise, where y is the vertical axis on a cost/damage scale, and P is the amount of pollution. Plot these curves and the equilibrium amount of pollution which is privately optimal for the firm. 2. Why is the marginal cost of abatement is downward sloping (with increasing pollution measured on the bottom axis as you go right). Give an example where this is a reasonable assumption 3. Suppose the marginal damage to society is MDS: y=P. Calculate the socially optimal amount of pollution. What ethical system does the ‘optimal amount of pollution’ belong? To…

(Figure: The Socially Optimal Quantity of Emissions from Coal Production) Use Figure The Socialy Optimal Quarety of Emissions from Coal Production in the figure, firms are the only beneficiaries of polution, and costs are borne solely by others in the society. Without government intervention Marginal social cost, marginal social benefit MSC of pollution MSB of pollution Quantity of pollution emissions (tons) O The outcome cannot be determined without more information Orms will continue to polute until the marginal benefit to them is $200 O firms will continue to pollute until the marginal benate to them is zero. O the quantity of pollution will be optimal.

No hand written solution Afirm has an industrial plant that emits pollutants into a town’s lake. The plant’s marginal abatement function is MAC= 200 – 0.5E and damages caused by its emissions are given by MD = 2E where emissions are in kg. per day. What is the socially efficient level of emissions from this plant? Illustrate this in a graph.   As an incentive to reduce emissions to the socially efficient level, government offers to pay the firm for each kg. of emissions it abates per day from this plant.   What subsidy per kg. should the government offer? If the plant abates to the socially efficient level of emissions, what total subsidy payment would the firm receive? Identify the area in your graph. How much better or worse off would the firm be compared to if it did no abating? Identify the area in your graph. What would be the net benefit to society if we pay the firm to reduce the plant’s emissions to the socially efficient level? Identify this area in your graph.
