This takes the form of an in-between view by adding a symmetric fan chart to the central forecast regarding the economic development in Germany. The main benefit of a fan chart is that it is pretty illustrative and, because of this, a fan chart is likely to convey more clearly the message and degree of uncertainty related to the projections.
We arrived at a more sceptical assessment regarding the associated question of whether such a fan chart should also reflect a risk assessment, that is whether – technically speaking – it should also be skewed. To do this, the impact of the various risk factors on the form and position of the density function of the forecast variable would have to be quantified.
