Economic models

We have extensive experience in modelling across a wide range of indications – our model experience includes budget impact models, cost effectiveness models, scenario models, cost calculator models, value-based pricing models, cost offset models, and cost utility models. Our experience is vast in this area and models have been developed for a large number of countries and with adaptations for different markets. We have developed models and model adaptations throughout Europe (including the EU5, eastern Europe and Scandinavia), on a Global scale, and for the US, Canada, Japan, Australia, Mexico and Brazil.
