This document provides an overview of key economic concepts: 1. Economics is the study of how to meet unlimited competing wants with limited resources. Resources include capital, labor, and natural resources. 2. A market economy encourages private ownership and competition through freedoms like choice of work, business ownership, and profit. Competition keeps prices low through both price and non-price factors. 3. Supply and demand determine prices - surplus creates low prices while shortage creates high prices. The business cycle stages of prosperity, recession, depression, and recovery impact industries differently.
