Question

What is cost-plus regulation?

Short answer

Cost-plus regulation is a pricing strategy used by regulators to control the prices charged by a monopolist or utility provider, ensuring that they do not take advantage of their market power to charge excessively high prices. The firm is allowed to charge a price that covers its costs plus a certain percentage markup, set by the regulatory authority. For example, if a utility company has a cost of production of $100 per unit and is allowed a 10% markup, the regulated price would be calculated as \(P = C + (m \times C) = 100 + (0.10 \times 100) = 110\). In this case, the company would be allowed to charge consumers $110 per unit of electricity under cost-plus regulation.

Step-by-step solution

Define cost-plus regulation

Cost-plus regulation is a pricing strategy used by regulators to control the prices charged by a monopolist or utility provider. In this strategy, the regulated firm is allowed to charge a price that covers its costs plus a certain percentage markup. This markup is typically set by the regulatory authority and is meant to provide the firm with a reasonable return on its investment.

Purpose of cost-plus regulation

The primary purpose of cost-plus regulation is to ensure that monopolies and utility providers do not take advantage of their market power to charge excessively high prices that harm consumers. By tying prices to the company's actual costs, regulators can shield consumers from being subjected to price gouging and guarantee a reasonable return for the firm, thereby encouraging investment and innovation.

Example of cost-plus regulation

An example of cost-plus regulation can be found in the electricity market. Suppose a utility company, PowerCorp, generates electricity and provides it to the consumers. The regulatory authority decides that PowerCorp should be allowed a 10% markup on its cost of production to ensure a fair return on its investment.

Calculate the regulated price

To calculate the regulated price, we need to consider the cost of production and the allowed markup percentage. In our example, let's say PowerCorp's cost of production (C) is $100 per unit, and the allowed markup percentage (m) is 10%. The markup amount can be calculated using the formula: \[Markup = m \times C = 0.10 \times 100 = 10\] Next, add the markup amount to the cost to find the regulated price (P): \[P = C + Markup = 100 + 10 = 110\] So, under cost-plus regulation, PowerCorp would be allowed to charge consumers $110 per unit of electricity.
