What are two common revenue forecasting methods used by states?

• A. Forecasting by lottery and magic eight ball.
• B. Econometric models and consensus/budget forecast methods.
• C. Historical trend analysis and random guessing.
• D. CPI-only growth projections.

Answer: (B)

States forecast revenues by combining quantitative models with informed judgment. Econometric models quantify how revenues respond to economic variables—like GDP growth, employment, and changes in the tax base—using statistical methods to project receipts under different economic scenarios. The consensus or budget forecast method brings together budget officials and outside economists to produce a single, agreed-upon projection that reflects policy changes, timing differences, and realistic expectations, helping align the forecast with legislative planning. These two approaches are common because the econometric method provides objective, data-driven projections, while consensus forecasting injects institutional knowledge and policy realism, reducing bias and ensuring forecasts are credible for budgeting. Other options aren’t used as credible methods: a lottery or magic eight ball isn’t a real forecasting method; historical trend analysis and random guessing don’t fully capture economic relationships or policy effects; CPI-only growth projections oversimplify how revenue responds to broader economic and tax-policy changes.
