Goods are objects that can satisfy people's wants.
Services are actions that can satisfy people's wants. People's choices about what goods and services to buy and consume determine how resources will be allocated. Whenever a choice is made, something is given up. The opportunity cost of a choice is the value of the best alternative given up. People whose wants are satisfied by using goods and services are called consumers.
