In macroeconomics Macroeconomics (from Greek prefix "macr-" meaning "large" + "economics") is a branch of economics that deals with the performance, structure, behavior and decision-making of the entire economy, be that a national, regional, or the global economy. Along with microeconomics, macroeconomics is one of the two most general and accounting Accountancy is the art of communicating financial information about a business entity to users such as shareholders and managers. The communication is generally in the financial´s form statements that show in money terms the economic resources under the control of management; the art lies in selecting the information that is relevant to the user, a good is contrasted with a service A service is the intangible equivalent of a good. Service provision is often an economic activity where the buyer does not generally, except by exclusive contract, obtain exclusive ownership of the thing purchased. The benefits of such a service, if priced, are held to be self-evident in the buyers willingness to pay for it. Public services are. In this sense, a good is defined as a physical (tangible Tangible property in law is, literally, anything which can be touched, and includes both real property and personal property (or moveable property), and stands in distinction to intangible property) product The noun product is defined as a "thing produced by labor or effort" or the "result of an act or a process", and stems from the verb produce, from the Latin prōdūce '(to) lead or bring forth'. Since 1575, the word "product" has referred to anything produced. Since 1695, the word has referred to "thing or things, capable of being delivered to a purchaser and involves the transfer of ownership Ownership is the state or fact of exclusive rights and control over property, which may be an object, land/real estate or intellectual property. Ownership involves multiple rights, collectively referred to as title, which may be separated and held by different parties. The concept of ownership has existed for thousands of years and in all cultures from seller A sale is the pinnacle activity involved in the selling products or services in return for money or other compensation. It is an act of completion of a commercial activity.[not in citation given] to customer A customer, also called client, buyer, or purchaser, is usually used to refer to a current or potential buyer or user of the products of an individual or organization, called the supplier, seller, or vendor. This is typically through purchasing or renting goods or services. However, in certain contexts, the term customer also includes by extension, say an apple, as opposed to an (intangible Intangible property, also known as incorporeal property, describes something which a person or corporation can have ownership of and can transfer ownership of to another person or corporation, but has no physical substance. It generally refers to statutory creations such as copyright, trademarks, or patents. It excludes tangible property like real) service, say a haircut. A more general term that preserves the distinction between goods and services is 'commodities,' like a flashlight. In microeconomics Microeconomics is a branch of economics that studies how the individual parts of the economy, the household and the firms, make decisions to allocate limited resources, typically in markets where goods or services are being bought and sold. Microeconomics examines how these decisions and behaviours affect the supply and demand for goods and, a 'good' is often used in this more inclusive sense of the word.

Utility characteristics of goods

A good is any object that increases the utility of the consumer/ product directely or indirectely. Goods are usually modeled as having diminishing marginal utility In economics, the marginal utility of a good or service is the utility gained from an increase (or decrease) in the consumption of that good or service. In general, preferences display diminishing marginal utility. That is, the first unit of consumption of a good or service yields more utility than the second and subsequent units. The concept of. Some things are useful, but not scarce enough to have monetary value, such as the Earth's atmosphere The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention , and reducing temperature extremes between day and night. Dry air contains roughly (by volume) 78% nitrogen, 21%, these are referred to as 'free goods Free goods are what is needed by the society and is available without limits . The free good is a term used in economics to describe a good that is not scarce. A free good is available in as great a quantity as desired with zero opportunity cost to society'.

In economics, a bad In economics, a bad is the opposite of a good. "Bads" can helpfully be thought of as any goods with a negative value to the consumer, or a negative price in the marketplace. Garbage is an example of a bad is the opposite of a good. Ultimately, whether an object is a good or a bad depends on each individual consumer and therefore, it is important to realize that not all goods are good all the time and not all goods are goods to all people.

Types of goods

public good In economics, a public good is a good that is non-rivalrous and non-excludable. 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. In the real world, there may be no such thing as an - private good public good - private good - common good - common-pool resource - club good - anti-rival good (includes household goods Household goods are goods and products used within households. They are the tangible and movable personal property placed in the living rooms, dining rooms, kitchens, family rooms, great rooms, bedrooms, bathrooms, recreation rooms, hallways, attics, and basements and other rooms of a house) - common good Common goods are defined in economics as goods which are rivalrous and non-excludable. Thus, they constitute one of the four main types of the most common typology of goods based on the criteria: - 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 - club good Club goods are a type of good in economics, sometimes classified as a subtype of public goods that are excludable but non-rivalrous, at least until reaching a point where congestion occurs. These goods are often provided by a natural monopoly - anti-rival good An anti-rival good is a good created by a process of reciprocal exchange for mutual benefit. Examples include free software and open source software

(non-)rivalrous good 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 good 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 complementary good A complementary good in economics is a good which is consumed with another good; its cross elasticity of demand is negative. – It is two goods that are bought and used together. This means that, if goods A and B are complements, an increase in the quantity demanded for good A results in an increase in demand for good B. An increase in the price vs. substitute good A substitute good, in contrast to a complementary good, is a good with a positive cross elasticity of demand.This means a good's demand is increased when the price of another good is increased. Conversely, the demand for a good is decreased when the price of another good is decreased. If goods A and B are substitutes, an increase in the price of A free good Free goods are what is needed by the society and is available without limits . The free good is a term used in economics to describe a good that is not scarce. A free good is available in as great a quantity as desired with zero opportunity cost to society vs. positional good In economics, Positional goods are products and services whose value is mostly a function of their ranking in desirability, in comparison to substitutes. The extent to which a good's value depends on such a ranking is referred to as its positionality. The term was coined by Fred Hirsch in 1976

(non-)durable good In economics, a durable good or a hard good is a good that does not quickly wear out, or more specifically, one that yields services or utility over time rather than being completely used up when used once. Most goods are therefore durable goods to a certain degree. These are goods that can last for a long time, such as refrigerators, cars, and - intermediate good Intermediate goods or producer goods are goods used as inputs in the production of other goods, such as partly finished goods. They are goods used in production of final goods. A firm may make then use intermediate goods, or make then sell, or buy then use them. In the production process, intermediate goods either become part of the final product, (producer good) - final good In economics final goods are goods that are ultimately consumed rather than used in the production of another good. For example, a car sold to a consumer is a final good; the components such as tires sold to the car manufacturer are not; they are intermediate goods used to make the final good - capital good In Marxian economics, capital goods originally referred to the means of production. Individuals, organizations and governments use capital goods in the production of other goods or commodities. Capital goods include factories, machinery, tools, equipment, and various buildings which are used to produce other products for consumption. Capital goods,

inferior good In consumer theory, an inferior good is a good that decreases in demand when consumer income rises, unlike normal goods, for which the opposite is observed. Normal goods are those for which consumers' demand increases when their income increases. Inferiority, in this sense, is an observable fact relating to affordability rather than a statement - normal good In economics, normal goods are any goods for which demand increases when income increases and falls when income decreases but price remains constant, i.e. with a positive income elasticity of demand. The term does not necessarily refer to the quality of the good - neutral good - ordinary good An ordinary good is a microeconomic concept used in consumer theory. It is defined as a good which creates increased demand when the price for the good drops or conversely decreased demand if the price for the good increases, ceteris paribus. It is the opposite of a Giffen good - Giffen good In economics and consumer theory, a Giffen good is one which people consume more of as price rises, violating the law of demand. In normal situations, as the price of a good rises, the substitution effect causes consumers to purchase less of it and more of substitute goods. In the Giffen good situation, cheaper close substitutes are not available - luxury good In economics, a luxury good is a good for which demand increases more than proportionally as income rises, in contrast to a "necessity good", for which demand is not related to income.[citation needed] - Veblen good In economics, Veblen goods are a group of commodities for which peoples' preference for buying them increases as a direct function of their price, as greater price confers greater status, instead of decreasing according to the law of demand. A Veblen good is often also a positional good - superior good Superior goods make up a larger proportion of consumption as income rises, and therefore are a type of normal goods in consumer theory. Such a good must possess two economic characteristics: it must be scarce, and, along with that, it must have a high price. The scarcity of the good can be natural or artificial; however, the general population

search good In economics, a search good is a product or service with features and characteristics easily evaluated before purchase. In a distinction originally due to Philip Nelson, a search good is contrasted with an experience good - (post-)experience good In economics, an experience good is a product or service where product characteristics such as quality or price are difficult to observe in advance, but these characteristics can be ascertained upon consumption. The concept is originally due to Philip Nelson, who contrasted an experience good with a search good - credence good A credence good is a term used in economics for a good whose utility impact is difficult or impossible for the consumer to ascertain. In contrast to experience goods, the utility gain or loss of credence goods is difficult to measure after consumption as well. The seller of the good knows the utility impact of the good, creating a situation of

merit good The concept of a merit good introduced in economics by Richard Musgrave is a commodity which is judged that an individual or society should have on the basis of some concept of need, rather than ability and willingness to pay. The term is, perhaps, less often used today than it was in the 1960s to 1980s but the concept still lies behind many - demerit good In economics, a demerit good is a good or service whose consumption is considered unhealthy, degrading, or otherwise socially undesirable due to the perceived negative effects on the consumers themselves. It is over-consumed if left to market forces. Examples of demerit goods include tobacco, alcoholic beverages, recreational drugs, gambling, junk

damaged good In economics, a damaged good is a good that has been deliberately limited in performance, quality or utility, typically for marketing reasons as part of a strategy of product differentiation - composite good In economics, demand for a good is often the focus as to a change in its price. A composite good is an abstraction used in economics that represents all goods in the relevant budget besides the one in question - intangible good An intangible good is a good that is intangible, meaning that it can not be touched, as opposed to a physical good. In an increasingly digitized world, intangible goods play a more and more important role in the economy. Virtually anything that is in a digital form and deliverable on the Internet can be considered an intangible good. A piece of
