Goods and services

Goods are items that are usually (but not always) tangible, such as pens, physical books, salt, apples, and hats. Services are activities provided by other people, who include architects, suppliers, contractors, technologists, teachers, doctors, lawn care workers, dentists, barbers, waiters, online servers, a digital book, a digital video game or a digital movie. Taken together, it is the production, distribution, and consumption of goods and services which underpins all economic activity and trade. According to economic theory, consumption of goods and services is assumed to provide utility (satisfaction) to the consumer or end-user, although businesses also consume goods and services in the course of producing other goods and services (see: Distribution: Channels and intermediaries). Physiocratic economists categorized production into productive labour and unproductive labour. Adam Smith expanded this thought by arguing that any economic activities directly related to material products (goods) were productive, and those activities which involved non-material production (services) were unproductive. This emphasis on material production was adapted by David Ricardo, Thomas Robert Malthus and John Stuart Mill, and influenced later Marxian economics. Other, mainly Italian, 18th-century economists maintained that all desired goods and services were productive. The division of consumables into services is a simplification: these are not discrete categories. Most business theorists see a continuum with pure service at one endpoint and pure tangible commodity goods at the other. Most products fall between these two extremes. For example, a restaurant provides a physical good (prepared food), but also provides services in the form of ambience, the setting and clearing of the table, etc. Although some utilities, such as electricity and communications service providers, exclusively provide services, other utilities deliver physical goods, such as water utilities.
