Calculating External Production Costs

A factory produces widgets, and its manufacturing process generates air pollution, which imposes a cost on the surrounding community. The socially efficient level of production is determined to be 1,000 widgets per day. At this output level, the factory's internal cost to produce one additional widget is $50, while the total cost to society (including the factory's cost and the pollution cost) for that additional widget is $72. What is the marginal external cost of producing the 1,000th widget?

Fertilizer Production and River Pollution

In a market with a negative production externality, the marginal social cost (MSC) of production is higher than the marginal private cost (MPC). The socially efficient level of output is achieved where the market price is equal to the MSC. Suppose that at this efficient output level, the market price is $150 per unit, and the marginal private cost for producers is $110 per unit. What does the $40 difference between these two values represent?

A paper mill's production process releases pollutants into a river, creating a cost for the downstream community. The socially efficient level of paper production is 10,000 reams per week. At this specific output level, the marginal cost to society for producing the 10,000th ream is $12, while the paper mill's private marginal cost for that same ream is $8. The marginal external cost of producing this 10,000th ream of paper is $____.

A chemical plant's production process pollutes a nearby river. The market for its product is competitive, with a constant price. The table below shows the plant's private costs and the total social costs at two different levels of output.

Based on this data, what is the marginal external cost at the socially efficient level of production?

A leather tannery's production process pollutes a river. The market price for its product is $500 per hide. The tannery operates where its marginal private cost (MPC) equals the price, producing 200 hides per week. At this output level of 200 hides, the marginal social cost (MSC) is $650. The socially efficient output level, where the price would equal the MSC, is determined to be 150 hides per week.

Statement: The marginal external cost at the socially efficient output of 150 hides is $150.

A factory produces a chemical, and its production process results in a negative externality. The market for this chemical is competitive, with a constant price of $90 per unit. The socially efficient level of production is determined to be 1,000 units. At this output level, the factory's marginal private cost (MPC) is $75. The factory, if left unregulated, would produce at the market equilibrium of 1,200 units, where its marginal private cost equals the price. At the market equilibrium output of 1,200 units, the marginal social cost (MSC) is $115. Based on this information, what is the marginal external cost at the socially efficient level of production?

Consider a market for paper production where the manufacturing process creates water pollution, a negative externality. The market is characterized by the following:

• An upward-sloping Marginal Private Cost (MPC) curve represents the firm's direct costs.
• An upward-sloping Marginal Social Cost (MSC) curve, which lies above the MPC curve, represents the total cost to society.
• The market price for paper is constant at $80 per ton.

Analysis of the market reveals these key points:

• The socially efficient level of output, where the price equals the MSC, is 4,000 tons.
• At this output of 4,000 tons, the firm's marginal private cost (MPC) is $55.
• The unregulated market equilibrium, where the price equals the MPC, occurs at 6,000 tons.

What is the marginal external cost at the socially efficient level of production?

The market for a specific industrial solvent is analyzed, where production generates a negative externality. The socially efficient level of production is determined to be 5,000 gallons. At this specific output level, the market price, which reflects the marginal social cost (MSC), is $85 per gallon. The firm's marginal private cost (MPC) to produce the 5,000th gallon is $60. What is the marginal external cost at the socially efficient output level?

In a market with a negative production externality, the marginal social cost (MSC) of production is higher than the marginal private cost (MPC). The socially efficient level of output is achieved where the market price is equal to the MSC. Suppose that at this efficient output level, the market price is $150 per unit, and the marginal private cost for producers is $110 per unit. What does the $40 difference between these two values represent?
