Merging models and experts

Abstract

It is argued that for specific forecast settings there must exist an optimally-sized model with forecasts that only need occasional adjustments by experts. The argument is built on recent evidence on the interaction between models and experts. A consequence of this is that the future research agenda should involve more interaction between researchers in model-based forecasting and those who are engaged in judgemental forecasting research.
