Analyzing an economic policy claim

Objective: Explain counterfactual and correlation versus causation, distinguish their meanings, and apply them to a described case.

Counterfactual: A counterfactual describes what would have happened without the action being evaluated. Correlation versus causation: Co-movement alone does not establish that one factor caused another. International comparisons require consistent units and clearly defined alternatives. Comparative advantage concerns opportunity cost, while absolute advantage concerns productive efficiency. Trade can increase total feasible consumption without distributing gains equally. Currency quotations must specify which unit is priced in which other unit. A policy claim needs evidence about mechanisms, adjustment costs, affected groups, and the relevant counterfactual rather than a slogan. Application: An analyst estimates a credible no-policy comparison. This most directly illustrates counterfactual. An outcome changes after a policy while other conditions also change. This most directly illustrates correlation versus causation.

Objective: Explain policy mechanism and distributional analysis, distinguish their meanings, and apply them to a described case.

Policy mechanism: A mechanism explains the pathway from an action to an outcome. Distributional analysis: Distributional analysis examines how effects differ across groups. International comparisons require consistent units and clearly defined alternatives. Comparative advantage concerns opportunity cost, while absolute advantage concerns productive efficiency. Trade can increase total feasible consumption without distributing gains equally. Currency quotations must specify which unit is priced in which other unit. A policy claim needs evidence about mechanisms, adjustment costs, affected groups, and the relevant counterfactual rather than a slogan. Application: A proposal links a price incentive to changed purchasing behavior. This most directly illustrates policy mechanism. A study separates impacts on workers, buyers, and owners. This most directly illustrates distributional analysis.

Objective: Explain assumption transparency and evidence qualification, distinguish their meanings, and apply them to a described case.

Assumption transparency: Transparency makes model choices and conditions inspectable. Evidence qualification: Qualification limits a conclusion to what its evidence actually supports. International comparisons require consistent units and clearly defined alternatives. Comparative advantage concerns opportunity cost, while absolute advantage concerns productive efficiency. Trade can increase total feasible consumption without distributing gains equally. Currency quotations must specify which unit is priced in which other unit. A policy claim needs evidence about mechanisms, adjustment costs, affected groups, and the relevant counterfactual rather than a slogan. Application: A report states its response-rate and time-horizon assumptions. This most directly illustrates assumption transparency. An evaluation reports uncertainty rather than promising universal success. This most directly illustrates evidence qualification.
