In economics Economics is the social science that analyzes the production, distribution, and consumption of goods and services. The term economics comes from the Ancient Greek οἰκονομία from οἶκος (oikos, "house") + νόμος (nomos, "custom" or "law"), hence "rules of the house(hold)". Current economic, a public good is a good In macroeconomics and accounting, a good is contrasted with a service. In this sense, a good is defined as a physical product, capable of being delivered to a purchaser and involves the transfer of ownership from seller to customer, say an apple, as opposed to an (intangible) service, say a haircut. A more general term that preserves the that is non-rivalrous In economics, a good is considered either rivalrous or nonrival. Rival goods are goods whose consumption by one consumer prevents simultaneous consumption by other consumers. Most goods, both durable and nondurable, are rival goods. A hammer is a durable rival good. One person's use of the hammer presents a significant barrier to others who desire and non-excludable In economics, a good or service is said to be excludable when it is possible to prevent people who have not paid for it from having access to it, and non-excludable when it is not possible to do so. Non-rivalry means that consumption of the good by one individual does not reduce availability of the good for consumption by others; and non-excludability 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 visits a doctor there is one less doctor's visit for everyone else, and it is possible to exclude others from visiting the doctor. This makes doctor visits a rivaled and excludable private good public good - private good - common good - common-pool resource - club good - anti-rival good. Conversely, breathing air does not significantly reduce the amount of air available to others, and people cannot be effectively excluded from using the air. This makes air a public good, albeit one that is economically trivial, since air is a free good. A less straight-forward example is the exchange of MP3 MPEG-1 Audio Layer 3 or MPEG-2 , more commonly referred to as MP3, is a patented digital audio encoding format using a form of lossy data compression. It is a common audio format for consumer audio storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on digital audio players 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 and photo files.
Non-rivalness and non-excludability may cause problems for the production of such goods. Specifically, some economists[by whom?] have argued that they may lead to instances of market failure In economics, a market failure occurs when there is an inefficient allocation of goods and services in a market. That is, there exists another outcome where market participants' overall gains from the new outcome outweigh their losses . Market failures can be viewed as scenarios where individuals' pursuit of pure self-interest leads to results, where uncoordinated markets A market is any one of a variety of different systems, institutions, procedures, social relations and infrastructures whereby persons trade, and goods and services are exchanged, forming part of the economy. It is an arrangement that allows buyers and sellers to exchange things. Competition is essential in markets, and separates market from trade 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 In economics, an externality is a cost or benefit, not transmitted through prices, incurred by a party who did not agree to the action causing the cost or benefit. A benefit in this case is called a positive externality or external benefit, while a cost is called a negative externality or external cost.
Graphically, non-rivalry means that if each of several individuals has a demand curve for a public good, then the individual demand curves are summed vertically to get the aggregate demand curve for the public good . This is in contrast to the procedure for deriving the aggregate demand for a private good, where individual demands are summed horizontally.

Terminology, and types of public goods
Paul A. Samuelson Paul Anthony Samuelson was an American economist, and the first American to win the Nobel Prize in Economics. The Swedish Royal Academies stated, when awarding the prize, that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory." Economic historian Randall E. Parker calls is usually credited as the first economist to develop the theory of public goods. In his classic 1954 paper The Pure Theory of Public Expenditure,[2] he defined a public good, or as he called it in the paper a "collective consumption good", as follows:
...[goods] which all enjoy in common in the sense that each individual's consumption of such a good leads to no subtractions from any other individual's consumption of that good...
This is the property that has become known as Non-rivalry In economics, a good is considered either rivalrous or nonrival. Rival goods are goods whose consumption by one consumer prevents simultaneous consumption by other consumers. Most goods, both durable and nondurable, are rival goods. A hammer is a durable rival good. One person's use of the hammer presents a significant barrier to others who desire. In addition a pure public good exhibits a second property called Non-excludability In economics, a good or service is said to be excludable when it is possible to prevent people who have not paid for it from having access to it, and non-excludable when it is not possible to do so: that is, it is impossible to exclude any individuals from consuming the good.
The opposite of a public good is a private good public good - private good - common good - common-pool resource - club good - anti-rival good, which does not possess these properties. A loaf of bread, for example, is a private good: its owner can exclude others from using it, and once it has been consumed, it cannot be used again.
A good which is rivalrous but non-excludable is sometimes called a common pool resource In economics, a common-pool resource , also called a common property resource, is a type of good consisting of a natural or human-made resource system (e.g. an irrigation system or fishing grounds), whose size or characteristics makes it costly, but not impossible, to exclude potential beneficiaries from obtaining benefits from its use. Unlike. Such goods raise similar issues to public goods: the mirror to the public goods problem for this case is sometimes called the tragedy of the commons The tragedy of the commons refers to a dilemma described in an influential article by that name written by Garrett Hardin and first published in the journal Science in 1968. The article describes a situation in which multiple individuals, acting independently, and solely and rationally consulting their own self-interest, will ultimately deplete a. For example, it is so difficult to enforce restrictions on deep sea fishing that the world's fish stocks can be seen as a non-excludable resource, but one which is finite and diminishing.
The definition of non-excludability states that it is impossible to exclude individuals from consumption. Technology now allows radio or TV broadcasts to be encrypted such that persons without a special decoder are excluded from the broadcast; however, an unencrypted Many forms of information Information, in its most restricted technical sense, is an ordered sequence of symbols. As a concept, however, information has many meanings. Moreover, the concept of information is closely related to notions of constraint, communication, control, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, and representation have characteristics of public goods. For example, a poem can be read by many people without reducing the consumption of that good by others; in this sense, it is non-rivalrous. Similarly, the information in most patents can be used by any party without reducing consumption of that good by others. Creative works may be excludable in some circumstances, however: the individual who wrote the poem may decline to share it with others by not publishing it. Copyrights Copyright is a set of exclusive rights granted to the author or creator of an original work, including the right to copy, distribute and adapt the work. Copyright does not protect ideas, only their expression or fixation. In most jurisdictions copyright arises upon fixation and does not need to be registered. Copyright owners have the exclusive and patents A patent is a set of exclusive rights granted by a state (national government) to an inventor or their assignee for a limited period of time in exchange for a public disclosure of an invention both encourage and inhibit the creation of such non-rival goods by providing temporary monopolies, or, in the terminology of public goods, providing a legal mechanism to enforce excludability for a limited period of time. For public goods, the "lost revenue" of the producer of the good is not part of the definition: a public good is a good whose consumption does not reduce any other's consumption of that good.[citation needed]
The economic concept of public goods should not be confused with the expression "the public good", which is usually an application of a collective ethical Ethics is a branch of philosophy that addresses questions about morality — that is, concepts such as good and evil, right and wrong, justice, virtue, etc notion of "the good" in political decision-making. Another common confusion is that public goods are goods provided by the public sector The public sector, sometimes referred to as the state sector is a part of the state that deals with either the production, delivery and allocation of goods and services by and for the government or its citizens, whether national, regional or local/municipal. Although it is often the case that Government A government is the organization, or agency through which a political unit exercises its authority, controls and administers public policy, and directs and controls the actions of its members or subjects is involved in producing public goods, this is not necessarily the case. Public goods may be naturally available. They may be produced by private individuals and firms, by non-state collective action As an explanation of social movements, an inquiry into collective action involves examining those factors that cause the setting of standards of social integration, as well as those factors which lead to standards of deviance and conflict. An explanation of a collective action in sociology will involve the explanation of those things which are, or they may not be produced at all.[citation needed]
The theoretical concept of public goods does not distinguish with regard to the geographical region in which a good may be produced or consumed. However, some theorists (such as Inge Kaul) use the term global public good This concept is an extension of Samuelson's notion of public goods to the economics of globalisation to mean a public good which is non-rival and non-excludable throughout the whole world, as opposed to a public good which exists in just one national area. Knowledge Knowledge is defined by the Oxford English Dictionary as expertise, and skills acquired by a person through experience or education; the theoretical or practical understanding of a subject; (ii) what is known in a particular field or in total; facts and information; or (iii) awareness or familiarity gained by experience of a fact or situation has been held to be an example of a global public good.[3]
Collective good
Collective goods (or social goods) of a sovereign nation Sovereignty is the quality of having supreme, independent authority over a territory. It can be found in a power to rule and make law that rests on a political fact for which no purely legal explanation can be provided. The concept has been discussed, debated and questioned throughout history, from the time of the Romans through to the present day, are defined public goods that could be delivered as private goods public good - private good - common good - common-pool resource - club good - anti-rival good, but are usually delivered by the government for various reasons, including social policy Social policy primarily refers to guidelines and interventions for the changing, maintenance or creation of living conditions that are conducive to human welfare. Thus, social policy is that part of public policy that has to do with social issues. The Malcolm Wiener Center for Social Policy at Harvard University describes it as "public policy, and finances from public funds like taxes To tax is to impose a financial charge or other levy upon a taxpayer (an individual or legal entity) by a state or the functional equivalent of a state such that failure to pay is punishable by law.
Note: Some writers have used the term public good to refer only to non-excludable pure public goods. They may then call excludable public goods club goods.[4]

The most common use of a firework is as part of a fireworks display. A fireworks event is a display of the effects produced by firework devices. Fireworks competitions are also regularly held at a number of places. Fireworks (devices) take, lighthouses A lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses or, in older times, from a fire and used as an aid to navigation and to pilots at sea or on inland waterways, clean air Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere and other environmental goods, and information goods, such as some software development Software development is the act of working to produce/create software. This software could be produced for a variety of purposes - the three most common purposes are to meet specific needs of a specific client/business, to meet a perceived need of some set of potential users , or for personal use (e.g. a scientist may write software to automate a, authorship An author is broadly defined as "the person who originates or gives existence to anything" and that authorship determines responsibility for what is created. Narrowly defined, an author is the originator of any written work, and invention An invention is a new composition, device, or process. An invention may be derived from a pre-existing model or idea, or it could be independently conceived in which case it may be a radical breakthrough. In addition, there is cultural invention, which is an innovative set of useful social behaviors adopted by people and passed on to others. Some goods (such as orphan drugs An orphan drug is a pharmaceutical agent that has been developed specifically to treat a rare medical condition, the condition itself being referred to as an orphan disease. The assignment of orphan status to a disease and to any drugs developed to treat it is a matter of public policy in many countries, and has resulted in medical breakthroughs) require special governmental incentives to be produced, but can't be classified as public goods since they don't fulfill the above requirements (Non-excludable and non-rivalrous.)
The provision of a lighthouse A lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses or, in older times, from a fire and used as an aid to navigation and to pilots at sea or on inland waterways has often been used as the standard example of a public good, since it is difficult to exclude ships from using its services. No ship's use detracts from that of others, but since most of the benefit of a lighthouse accrues to ships using particular ports, lighthouse maintenance fees can often profitably be bundled with port fees (Ronald Coase Ronald Harry Coase is a British economist and the Clifton R. Musser Professor Emeritus of Economics at the University of Chicago Law School. After studying with the University of London External Programme in 1927–29, Coase entered the London School of Economics where he took courses with Arnold Plant. He received the Nobel Prize in Economics in 1, The Lighthouse in Economics 1974). This has been sufficient to fund actual lighthouses.
Technological progress can create new public goods. The most simple examples are street lights, which are relatively recent inventions (by historical standards). One person's enjoyment of them does not detract from other persons' enjoyment, and it currently would be prohibitively expensive to charge individuals separately for the amount of light they presumably use. On the other hand, a public good's status may change over time. Technological progress can significantly impact excludability of traditional public goods: encryption allows broadcasters Broadcasting is the distribution of audio and video content to a dispersed audience via radio, television, or other, often digital transmission media. Receiving parties may include the general public or a relatively large subset of thereof to sell individual access to their programming. The costs for electronic road pricing Road pricing is an economic concept regarding the various direct charges applied for the use of roads. The road charges includes fuel taxes, licence fees, parking taxes, tolls, and congestion charges, including those which may vary by time of day, by the specific road, or by the specific vehicle type, being used. Road pricing has two distinct have fallen dramatically, paving the way for detailed billing based on actual use.
There is some question as to whether defense is a public good. Murray Rothbard Murray Newton Rothbard was an American intellectual, individualist anarchist, author, and economist of the Austrian School who helped define modern libertarianism and popularized a form of free-market anarchism he termed "anarcho-capitalism". Rothbard wrote over twenty books and is considered by some to be "dean of the Austrian argues, "'national defense' is surely not an absolute good with only one unit of supply. It consists of specific resources committed in certain definite and concrete ways—and these resources are necessarily scarce. A ring of defense bases around New York, for example, cuts down the amount possibly available around San Francisco."[5] Jeffrey Rogers Hummel and Don Lavoie note, "Americans in Alaska and Hawaii could very easily be excluded from the U.S. government's defense perimeter, and doing so might enhance the military value of at least conventional U.S. forces to Americans in the other forty-eight states. But, in general, an additional ICBM in the U.S. arsenal can simultaneously protect everyone within the country without diminishing its services."[6]
The free rider problem
Main article: Free rider problem In economics, collective bargaining, psychology, and political science, "free riders" are those who consume more than their fair share of a public resource, or shoulder less than a fair share of the costs of its production. Free riding is usually considered to be an economic "problem" only when it leads to the non-production orPublic goods provide a very important example of market failure, in which market-like behavior of individual gain-seeking does not produce efficient results. The production of public goods results in positive externalities which are not remunerated. If private organizations don't reap all the benefits of a public good which they have produced, their incentives to produce it voluntarily might be insufficient. Consumers can take advantage of public goods without contributing sufficiently to their creation. This is called the free rider problem, or occasionally, the "easy rider problem" (because consumer's contributions will be small but non-zero).
The free rider problem depends on a conception of the human being as homo economicus: purely rational and also purely selfish—extremely individualistic, considering only those benefits and costs that directly affect him or her. Public goods give such a person an incentive to be a free rider.
For example, consider national defense, a standard example of a pure public good. Suppose homo economicus thinks about exerting some extra effort to defend the nation. The benefits to the individual of this effort would be very low, since the benefits would be distributed among all of the millions of other people in the country. There is also a very high possibility that he or she could get injured or killed during the course of his or her military service.
On the other hand, the free rider knows that he or she cannot be excluded from the benefits of national defense, regardless of whether he or she contributes to it. There is also no way that these benefits can be split up and distributed as individual parcels to people. The free rider would not voluntarily exert any extra effort, unless there is some inherent pleasure or material reward for doing so (for example, money paid by the government, as with an all-volunteer army or mercenaries).
In the case of information goods, an inventor of a new product may benefit all of society, but hardly anyone is willing to pay for the invention if they can benefit from it for free.
