kizárható

Kizárható is a Hungarian word that translates to "excludable" or "can be excluded" in English. It is most commonly used in the context of economics, particularly when discussing public goods. A good that is kizárható is one that can prevent non-payers from consuming it. This is in contrast to non-excludable goods, where it is difficult or impossible to prevent people from using the good, even if they haven't paid for it.

The concept of excludability is a key characteristic used to classify different types of goods. Goods are typically categorized into four groups based on their excludability and rivalry: private goods, public goods, club goods, and common resources. Private goods are both excludable and rivalrous. Public goods are non-excludable and non-rivalrous. Club goods are excludable but non-rivalrous, while common resources are non-excludable but rivalrous.

In practical terms, excludability means that a seller can prevent someone from accessing a good or service if they do not pay the required price. For instance, a movie ticket is excludable because the cinema can deny entry to individuals who have not purchased a ticket. Similarly, a private road is excludable as tolls can be charged to use it. Understanding excludability is crucial for analyzing market failures, the provision of public services, and the design of efficient economic policies. When a good is excludable, it can often be provided through private markets because producers can charge for their products and services.
