Chemistry - Private good

In economics Private good is an opposite of the public good.

Its main features are:

excludability (also referred in this context as rivalry) - cannot be consumed by everybody since consumption by one person reduces or excludes consumption by another
depletability (it is finite)

Private goods are almost exclusively made for profit.

An example of the private good is bread: there is a finite amount of it, and bread eaten by a given person cannot be consumed by another.

One of the most common way of looking at goods in economy, illustrated in the table below, is the classic division based on:

Classic division of goods in economy		Exclusion from consumption
Classic division of goods in economy		YES	NO
Competition in consumption	YES	private good: food, clothing, toys, furniture, cars	common good: natural environment
Competition in consumption	NO	club good: private schools, cinemas, clubs,	public good: national security (army and police forces)
