Answer:
Public goods are goods where it is too difficult to seperate between payers and non payers (The technical term is non-excludable) and where there are plenty of the good and so there is no reason to deny someone else use of the good (non-rivaled). For example, street lighting is a public good. The good is non-rivaled because somebody using the lighting does not make it less bright for other users. It is also non-excludable as you cannot make people pay for the good as they use it (You don't see coin slots on lamposts do you?) Goods such as Public Heathcare (NHS etc) are made public through the use of government, as it is common in many countries to charge people for visiting a doctor with an illness but the government uses its funds to allow the good to be available to everyone without causing this to impact anyone elses healthcare. (Obviously things are not as perfect in the real world as we do need to queue for our doctor, drugs etc). A private good is the opposite of a public good. It can no longer be used after consumption and is it is easy to make people pay for the good. An example of a private good would be a BigMac. Once someone has eaten the BigMac, there is none left for anyone else. Also it is easy to charge people seperately for their BigMacs.

In economics, a public good is a good that is non-rivaled and non-excludable. This means, respectively, that consumption of the good by one individual does not reduce availability of the good for consumption by others; and that no one can be effectively excluded from using the good.[1] In the real world, there may be no such thing as an absolutely non-rivaled and non-excludable good; but economists think that some goods approximate the concept closely enough for the analysis to be economically useful. For example, if one individual drinks a milkshake, there is no milkshake left for anyone else, and it is possible to exclude others from consuming the milkshake; it is a rivaled and excludable private good. Conversely, breathing air neither significantly reduces the amount of air available to others, nor can people be effectively excluded from using the air. This makes it a public good, but one that is economically trivial, as air is a free good. A less straight-forward example is the exchange of MP3 music files on the internet: the use of these files by any one person does not restrict the use by anyone else and there is little effective control over the exchange of these music files. Non-rivalness and non-excludability may cause problems for the production of such goods. Specifically, some economists have argued that they may lead to instances of market failure, where uncoordinated markets driven by parties working in their own self interest are unable to provide these goods in desired quantities. These issues are known as public goods problems, and there is a good deal of debate and literature on how to measure their significance to an economy, and to identify the best remedies. These debates can become important to political arguments about the role of markets in the economy. More technically, public goods problems are related to the broader issue of externalities. A private good is defined in economics as a good that exhibits these properties: * Excludable - it is reasonably possible to prevent a class of consumers (e.g. those who have not paid for it) from consuming the good. * Rivalrous - consumptions by one consumer prevents simultaneous consumption by other consumers. Private goods satisfies an individual want while public good satisfies a collective want of the society. A private good is the opposite of a public good, as they are almost exclusively made for profit. An example of the private good is bread: bread eaten by a given person cannot be consumed by another (rivalry), and it is easy for a baker to refuse to trade a loaf (excludable).
