Final answer:
Service firms offer non-tangible value like healthcare, education, and legal or financial consultations. They play a significant role in the economy, constituting a major portion of the GDP.
Step-by-step explanation:
The market for services encompasses a wide array of businesses that provide non-tangible value to consumers and companies. Examples of service firms include entities offering professional services such as healthcare providers, education institutions, and firms providing legal and financial services. These firms, unlike those in the goods market, focus primarily on offerings that cannot be physically handled, such as consultations, treatments, and education. As noted, services make up a significant portion of the Gross Domestic Product (GDP) and reflect the modern evolution of the economy from manufacturing tangible goods to providing intangible value.
