External Effect (Externality)
An external effect, or externality, is a cost or benefit from an economic activity that affects a third party who is not directly involved in that activity. These uncompensated spillover effects are not reflected in market prices. Costs imposed on others are termed negative externalities (or external diseconomies), such as pollution from a factory. Benefits conferred on others are known as positive externalities (or external economies), such as a beekeeper's bees pollinating a nearby orchard.

A large manufacturing plant produces steel and, in the process, releases pollutants into the air. These pollutants cause respiratory problems for residents in a nearby town, leading to increased healthcare costs for them. The plant does not pay for these healthcare costs. Which statement best analyzes why this scenario represents a market failure?
Analyzing a Market Failure Scenario
Match each scenario with the primary cause of market failure it illustrates.
Explaining Market Inefficiency
The mere presence of a single firm with significant control over the market price is, in and of itself, a market failure.
Contrasting Mechanisms of Market Failure
When a firm's production process creates pollution that harms the local environment without the firm paying for the damages, this is a type of market failure caused by a negative ________.
Consider two scenarios. Scenario 1: A chemical factory saves money by dumping waste into a river, which pollutes the water for a downstream fishing village, harming their fish stocks. Scenario 2: A single company holds the patent for a life-saving drug and sells it for a price ten times higher than its production cost, making it unaffordable for some patients who need it. Which statement best evaluates the market failures in these scenarios?

An apple orchard operates next to a beekeeper. The bees pollinate the apple blossoms, which increases the orchard's fruit yield. The apple blossoms, in turn, provide nectar for the bees, which increases the beekeeper's honey production. Neither party pays the other for these services. Which statement provides the most accurate economic analysis of this situation?

Policy Evaluation for a Noise Externality
A large chemical company has a manufacturing division that releases pollutants into a river. Downstream, another division of the same company operates a fish farm, which suffers reduced yields due to the pollution. This situation is an example of a negative externality.
Arrange the following events in the correct logical sequence to illustrate how a negative production externality leads to an inefficient market outcome.
