Putting the results in context
As any other method, econometric models are subject to bias. Therefore, as a general rule, you should not be too confident the results of a single econometric model. Instead of trusting the results from single econometric models, forecasting research recommends to look at combined econometric models or, even better, a combined forecast that relies on different methods and data.
