nonrival

This is the property that has become known as 'Nonrival good'.

The television itself is a rival good, but television broadcasts are nonrival goods.

Goods that are both nonrival and non-excludable are called public goods.

Information is particularly suited to gift economy, as information is a nonrival good and can be gifted at practically no cost.

In a broader sense, it can also include free granting of use rights to a good that can be treated as a nonrival good, such as information.

Rival products decrease as they are used (e.g. pounds of flour), the consumption of nonrival products (e.g. listening to a song) does not decrease their availability for further consumption.

This is because the arbitrages are essentially drawn from a pool of finite size; although information about how to capture arbitrages is a nonrival good, the arbitrages themselves are a rival good.
