In economics, goods are materials that satisfy human wants and provide utility, for example, to a consumer making a purchase of a satisfying product. A common distinction is made between goods that are tangible property , and services, which are non-Physical. A good may be a consumable item that is useful to people but scarce in relation to its demand, so that human effort is required to obtain it. In contrast, free goods, such as air , are naturally in abundant supply and need no conscious effort to obtain them. Personal goods are things such as televisions, living room furniture , wallets, cellular telephones, almost anything owned or used on a daily basis that is not food related. Commercial goods are construed as any tangible product that is manufactured and then made available for supply to be used in an industry of commerce. Commercial goods could be tractors, commercial vehicles , mobile structures, airplanes and even roofing materials. Commercial and personal goods as categories are very broad and cover almost everything a person sees from the time they awake in their home, on their commute to work and arrival in the work place.
Commodities may be used as a synonym for economic goods but often refer to marketable raw materials and primary products.
Although in economic theory all goods are considered tangible, in reality certain classes of goods, such as information , only take intangible forms.
