**2. Methods and Materials**

The modelling tool that is proposed in this analysis has two main components: a bottom-up approach, used together with the top-down macro-economic Fully Interregional Dynamic Econometric Long-term Input-Output model (FIDELIO). In this section, we first describe the two models (in Sections 2.1 and 2.2, respectively). Next, Section 2.3 describes the necessary further steps to link the two approaches, and it o ffers a graphic representation of the methodological proposal.
