Summary
Economics is a social science that develops models based on assumptions to understand complex interactions, often using the ceteris paribus assumption to simplify analysis.
- Economics as a social science — the study of how societies use resources and make choices. Example: Unlike natural sciences, economics cannot conduct controlled experiments.
- Model — a simplified representation of reality used to predict economic outcomes. Example: A supply and demand graph showing how price affects quantity.
- Ceteris paribus — a Latin phrase meaning "all other things being equal." Example: Analyzing the effect of price on demand while keeping other factors constant.
