Economic analysis is an umbrella for several different jobs. It may describe who chose what under which constraints, use a model to expose a mechanism, estimate a relationship from data, predict under stated assumptions, evaluate outcomes against a criterion, or inform a recommendation. A strong analysis names its job before presenting a result.
Do not let verbs smuggle in evidence
“Costs rose after the rule changed” describes a sequence. “The rule caused the increase” requires a causal design or other supporting evidence. “The rule is undesirable” adds an evaluative criterion. “Repeal it” adds a recommendation, authority, alternatives, and consequences. Each step makes a stronger and different claim.
Models and data play complementary roles. A model can make assumptions and mechanisms explicit; data can describe or estimate what occurred under a defined design. Neither alone guarantees that the mechanism caused an observed outcome or that one action is preferred.
A reviewable analytical record
State the question, unit of analysis, decision or population, time period, constraints, model, data source, counterfactual, assumptions, uncertainty, and claim boundary. Then say what evidence would change the conclusion.
Positive analysis, normative analysis, and marginal analysis are narrower forms of economic analysis. They are not interchangeable: one can test a descriptive claim, compare increments, and still leave the value judgment or decision unresolved.
