Economics is the study of how to meet unlimited wants with limited resources. It involves the economic activities of consumption, production, exchange, and distribution. Consumption is using goods and services, while production is making goods and services. Exchange involves trading resources for goods through prices, wages, rents, etc. Distribution divides income among resource owners. Goods are tangible objects while services are intangible acts. Economic resources include land, labor, capital, and entrepreneurship which are used to produce and distribute goods in an economy. Scarcity means not enough resources to meet all wants. Basic economic questions address what and how to produce goods, and who they are produced for.
