CETERIS PARIBUS

Summary

Ceteris paribus is a fundamental analytical tool in economics that means 'all other things being equal' in Latin. It's used when economists want to study how one specific factor affects an outcome while assuming all other relevant factors remain unchanged. Think of it like a controlled experiment - you change one variable at a time to see its isolated effect. For example, when studying how price affects demand, ceteris paribus assumes income, preferences, and other factors stay the same.

Usage Context

Essential for understanding economic models, analyzing cause-and-effect relationships, interpreting graphs and data, and conducting proper economic analysis throughout the course.

Common Confusions
