Abstract: | In Virginia, major differences between revenue forecasts and actual revenue collections raised questions from legislators about the adequacy of the state's econometric forecasting models and the forecasting process itself. Consequently, Virginia's process and models were examined by the Joint Legislative Audit and Review Commission (JLARC), a legislative watchdog agency. The review found most of the differences could be attributed to declining economic factors and not poor forecasting. However, a surprisingly large component of the forecast was based on undocumented judgmental inputs that required greater oversight. Other states in similar circumstances may wish to evaluate their own forecasting process and econometric models using the JLARC approach. |
