Model uncertainties
Models are by definition affected by uncertainties (in input data, input parameters, scenario definitions, etc.). Have the model uncertainties been quantified? Are uncertainties accounted for in your simulations?
- response
- no
- details
- CGE models routinely perform sensitivity analyses with respect to the value of key parameters or assumptions regarding the model structure. DG Trade for its in-house analyses has not engaged in quantifying these uncertainties. However, sensitivity analyses with respect to key parameters have been carried out e.g. Laborde, D., Padella, M., Edwards, R. and Marelli, L. (2014) (see references)
