3. The effect of negative externalities on the optimal quantityof consumption Consider the market for pharmaceuticals. Suppose that a pharmaceutical factory dumps toxic waste into a nearby river, creating a negative externality for those living downstream from the factory. Producing additional pharmaceuticals imposes a constant per-unit external cost of $280. The following graph shows the demand (private value) curve and the supply (private cost) curve for pharmaceuticals. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $280 per unit.

3. The effect of negative externalities on the optimal quantity of consumption 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 marginal external cost (MEC) of $165 per ton. The following graph shows the demand (marginal private benefits, or MPB) curve and the supply (marginal private costs, or MPC) curve for steel. Use the purple points (diamond symbol) to plot the marginal social costs (MSC) curve when the marginal external cost is $165 per ton.

QUESTION 10 Suppose that a firm in a competitive market produces electricity by burning coal. The production process creates a negative externality of air pollution. The firm only cares about its private benefits and costs so it will produce a quantity where O the price of electricity it is paid equals the marginal private cost of producing electricity O the marginal value of electricity to society equals the marginal social cost to society the cost of the externality is maximized O the transaction costs of private bargaining are minimized

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. Note: Drop lines will extend to both axes automatically. DERIVATE QUARKET O5OCIAL SSOCIAL SPRVATE QUANTITY OF CARS From society's standpoint, the market is producing cars.

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.
