services — English
Gainful transactions between willing participants while no tangible goods need to change hands. One party might have specialised knowledge which the other party might need. Often, the only thing that changes hands is the money which the receiving party pays for the specialised knowledge or service of the service provider. The service sector of the economy includes an extremely wide variety of services. Educational, medical, legal, cultural, artistic, psychological, recreational, hospitality, transport, security, and many other services are needed by everybody in a modern society. The service providers are often registered professionals with specific qualifications. Illegal services are not generally included, but in certain countries sexual services form part of the legal array of services. Services form an immense proportion of the economy in the developed countries (see “development” and “dual economy”). In the developing countries and countries in transition, services form a smaller proportion of the economy and production, while manufacturing still exceeds the service sector in importance. Services form part of the tertiary sector of an economy (see “countries in transition”, “development”, “dual economy” and “quaternary economic activities”).
