Putting the results in context
As any other method, models are subject to bias. Therefore, as a general rule, you should not be overly confident the results of an individual econometric model. Rather than relying on results from single models, the recommended strategy rely on combined models or, even better, a combined forecast that incorporates different methods and data.
