4. Efficiency in the presence of externalities Cars impose many external costs on society: carbon dioxide emissions that contribute to air pollution, congestion on roadways, and so on. Therefore, the market quantity of cars is not equal to the efficient quantity. The following graph shows the private demand for cars, the private supply of cars, and the social supply of cars, which incorporates both private costs and external costs. Use the black point (plus symbol) to indicate the market quantity. Next, use the purple point (diamond symbol) to indicate the socially optimum quantity.

3. The effect of negative externalities on the optimal quantityof consumption Consider the market for paper. Suppose that a paper factory dumps toxic waste into a nearby river, creating a negative externality for those living downstream from the factory. Producing an additional ton of paper imposes a constant external cost of $385 per ton. The following graph shows the demand (private value) curve and the supply (private cost) curve for paper. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $385 per ton.

Parks confer many external benefits on society: open space, trees that reduce pollution, and so on. Therefore, the market equilibrium quantity of parks is not equal to the socially optimal quantity. The following graph shows the demand for parks (their private value), the supply of parks (the private cost of producing them), and the social value of parks, including both the private value and external benefits. Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple point (diamond symbol) to indicate the socially optimal quantity.
3. Now reconsider the issue of soybeans from the perspective of Chinese consumers. Assume you are a Chinese consumer who drinks soymilk each day. Demonstrate using a graph how your consumption of soymilk differs from the socially optimal level. Is the price you pay for soymilk in current market conditions the correct amount, too high, or too low? Why? Ensure that you label your graph correctly (all curves, axes, price and quantities labeled). Show the deadweight loss of soymilk consumption, and what price should be charged for soymilk to move the amount of soymilk you drink to the optimal level.

3. The effect of negative externalities on the optimal quantity of consumption 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 $300. 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 $300 per unit. 1000 900 800 700 600 500 400 300 200 PRICE (Dollars per unit of electricity) 100 ப 0 0 1 2 ° 3 0 ° 4 ° QUANTITY (Units of electricity) 5 6 Supply (Private Cost) Demand (Private Value) Social Cost ?

Air horns impose many external costs on society: the risk of being deafened, the annoyance of being awakened in the middle of the night, and so on. Therefore, the market equilibrium quantity of air horns is not equal to the socially optimal quantity. The following graph shows the demand for air horns (their private value), the supply of air horns (the private cost of producing them), and the social cost of air horns, including both the private cost and external costs. Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple point (diamond symbol) to indicate the socially optimal quantity.
3. Efficiency in the presence of externalities Roses confer many external benefits on society: the beauty they add to a room or garden, the wonderful aroma they give off, and so on. Therefore, the market equilibrium quantity of roses is not equal to the socially optimal quantity. The following graph shows the demand for roses (their private value), the supply of roses (the private cost of producing them), and the social value of roses (the private value and external benefits). Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple point (diamond symbol) to indicate the socially optimal quantity.
