3. The effect of negative externalities on the optimal quantity of consumption Consider the market for bolts. Suppose that a hardware factory dumps toxic waste into a nearby river, creating a negative externality for those living downstream from the factory. Producing an additional ton of bolts 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 bolts. Use the purple points (diamond symbol) to plot the soclal cost curve when the external cost is \( \$ 385 \) per ton. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is \( \$ 385 \) per ton. The market equilibrium quantity is tons of boits, but the socially optimal quantity of boit production is tons. To create an incentive for the firm to produce the socially optimal quantity of bolts, the government could impose a of boles,
