Facts and opinions: Empirical economics is about facts and causal relationships, while normative economics is about opinions and what policies should be implemented.
Descriptive and Prescriptive: Empirical economics describes economic phenomena and relationships as they are, while normative economics dictates how the economy should operate.
Testability: Empirical economic statements can be tested for validity by referencing empirical data, while normative statements cannot be tested in this way because they are based on value judgments
