Explanation:

Positive economics (as opposed to normative economics) is the branch of economics that concerns the description, quantification and explanation of economic phenomena. It focuses on facts and cause-and-effect behavioral relationships and notes that economic theories  must be consistent with existing observations.

Positive economics as science concerns analysis of economic behavior to determine what is. Positive economics was once known as value-free (German: wertfrei) economics. Examples of positive economic statements are "the unemployment rate in France is higher than that in the United States," or “an increase in government spending would lower the unemployment rate.”
