The demand for cigarettes is given by P​ = 450-0.2Q. Cigarettes are manufactured at a constant marginal cost of 50 and sold in a competitive market. What is the quantity of cigarettes sold in​ equilibrium? QPrivate= 2000.00 If cigarettes generate a marginal external cost of MEC​ =0.20​Q, what is the socially optimal level of​ cigarettes? QSocially optimal​= 1000.00 My Question is I want to know how we can get the answer which are 2000 and 1000? What is the calculation for the answer of the question above?

Suppose that flu shots create a positive externality equal to $10 per shot. Further suppose that the government offers a $7-per-shot subsidy to producers. What is the relationship between the equilibrium quantity and the socially optimal quantity of flu shots produced? Group of answer choices They are equal. The equilibrium quantity is greater than the socially optimal quantity. The equilibrium quantity is less than the socially optimal quantity. There is not enough information to answer the question.

The table below shows cost data for producing different amounts of oil. The market for oil produces negative externalities in the form of pollution and environmental damage.

Consider the market for electricity. Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $240. The following graph shows the demand (private value) curve and the supply (private cost) curve for electricity. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $240 per unit. PRICE (Dollars per unit of electricity) 800 720 640 560 480 400+ 320 240 Supply (Private Cost) Demand (Private Value) 160 [- 80 0 0 1 2 3 4 5 6 7 QUANTITY (Units of electricity) Social Cost ? The market equilibrium quantity is units of electricity, but the socially optimal quantity of electricity production is units. To create an incentive for the firm to produce the socially optimal quantity of electricity, the government could impose a unit of electricity. of per
