Relationship Between Positive Externalities and Public Goods
Certain actions that produce external benefits for many people can also be classified as the provision of a public good. This occurs when one individual or entity bears the cost of an action, but the resulting benefits are widespread and accessible to others. For instance, if a single farmer helps fund an irrigation project, all local farmers benefit, making the project a community public good. Similarly, when one country implements policies to lower carbon emissions, all nations benefit, classifying CO2 reduction as a global public good.

Economic Analysis of a Private Garden
When an activity generates a positive externality, the private market equilibrium results in a quantity of the good being produced that is greater than the socially optimal quantity.
A beekeeper places hives next to an apple orchard. The bees pollinate the apple blossoms, which increases the orchard's apple yield, while also producing honey that the beekeeper sells. The beekeeper makes decisions about the number of hives based solely on the profitability of honey. Match each economic term below to the description that best represents it in this scenario.
When the social benefit of an activity is greater than the private benefit received by the decision-maker, a free market without intervention will tend to ________ the activity relative to the socially optimal level.

A software developer spends their free time creating a high-quality, open-source data encryption tool and releases it online for free. Anyone can download and use it to protect their digital privacy. The developer receives no payment but gains some personal satisfaction. However, the widespread use of this tool significantly enhances internet security for thousands of users, protecting them from data theft. If the total monetary value of this protection for all users is very large, but the developer chooses to work on other paid projects instead of improving the tool, which economic principle best explains this outcome?

When an action creates a valuable benefit for third parties who do not pay for it, the resulting good or service is typically overproduced from society's point of view because so many people benefit.
The Community Garden
When a private firm's research into a new battery technology creates foundational knowledge that competitors can freely use to improve their own products, the firm is generating a significant positive externality. Because the firm cannot capture the full social value of its discovery, it has a reduced incentive to invest in this type of research. This scenario typically leads to the ________ of such foundational knowledge from a societal perspective.
A private, profit-maximizing shipping company is considering building a lighthouse on a treacherous coastline. The total value of prevented shipwrecks for all vessels (including those of competing companies) would be $50 million, while the cost to build and maintain the lighthouse is $10 million. The company's own ships would receive only $3 million of that total benefit. From an economic standpoint, which statement best explains why the company will likely decide not to build the lighthouse?
