A factory operates in a competitive market and produces at the quantity where its marginal private cost equals the market price, maximizing its own profit. This production process, however, pollutes a river, imposing a cost on a downstream fishery. If the factory were to reduce its output by a single, infinitesimally small unit from this profit-maximizing level, what would be the immediate effect on the profits of the factory and the fishery?

Analyzing Social Surplus from a Production Change

Consider a profit-maximizing firm operating in a competitive market, whose production process generates a negative externality. A statement is made: 'An infinitesimally small, mandated reduction in output from the firm's current level will necessarily lead to a situation where the monetary gain to those harmed by the externality is greater than the monetary loss to the firm.' Is this statement true or false?

The Calculus of Social Gains

A competitive firm's profit is maximized at the output level where the market price equals its marginal private cost. Consequently, for an infinitesimally small reduction in output starting from this profit-maximizing point, the change in the firm's profit is effectively ________.

A company's production process generates a negative externality that harms a third party. The company is currently producing at its private profit-maximizing quantity, where the market price is exactly equal to its marginal private cost. Consider the effects of a single, infinitesimally small reduction in the company's output from this point. Match each of the following economic effects with its correct description in this specific scenario.

A firm's production process generates a negative externality affecting a third party. The firm is currently producing at its private profit-maximizing output level. An economist argues that a small reduction in output from this point can create a net social gain. Arrange the following statements to reconstruct the logical flow of this argument.
