Understanding Economic Systems

Macroeconomics and Microeconomics

The state of the economy affects both people and businesses. How you spend your money (or save it) is a personal economic decision. Whether you continue in school and whether you work part-time are also economic decisions. Every business also operates within the economy. Based on their economic expectations, businesses decide what products to produce, how to price them, how many people to employ, how much to pay these employees, how much to expand the business, and so on.

Economics has two main subareas. Macroeconomics is the study of the economy as a whole. It looks at aggregate data for large groups of people, companies, or products considered as a whole. In contrast, microeconomics focuses on individual parts of the economy, such as households or firms.

Both macroeconomics and microeconomics offer a valuable outlook on the economy. For example, Ford might use both to decide whether to introduce a new line of vehicles. The company would consider such macroeconomic factors as the national level of personal income, the unemployment rate, interest rates, fuel costs, and the national level of sales of new vehicles. From a microeconomic viewpoint, Ford would judge consumer demand for new vehicles versus the existing supply, competing models, labor and material costs and availability, and current prices and sales incentives.
