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?

not applicable
The type of analysis carried out with RHOMOLO, that is scenario analysis, can take care of uncertainties by simulating several alternative scenarios to be compared with the baseline one.

    Sensitivity analysis

    Sensitivity analysis helps identifying the uncertain inputs mostly responsible for the uncertainty in the model responses. Has the model undergone sensitivity analysis?

    yes
    Sensitivity analysis is an integral part of our modelling approach and is systematically performed with every model analysis. During each evaluation, we examine how variations in key parameters influence the model outputs by adjusting these critical inputs systematically and observing the resulting changes in responses. For example, when analysing labour market policies using RHOMOLO, we modify the labour substitution elasticities in the production function to evaluate their effect on employment outcomes, wage adjustments and overall economic efficiency.

      Have model results been published in peer-reviewed articles?

      yes
      The RHOMOLO model and its various iterations have been extensively validated and recognised within the academic community through regular publication in prestigious, peer-reviewed journals. It has appeared in numerous scholarly articles in top-tier journals, including Regional Studies, Spatial Economic Analysis and the European Journal of Political Economy, thereby demonstrating its robustness and relevance in addressing contemporary challenges in economic and spatial analysis.

        Has the model formally undergone scientific review by a panel of international experts?

        Please note that this does not refer to the cases when model results were validated by stakeholders.

        yes

          Model validation

          Has model validation been done? Have model predictions been confronted with observed data (ex-post)?

          not applicable
          Model projections cannot and should not be confronted with observed data because RHOMOLO is not a forecast model.

            Transparency

            To what extent do input data come from publicly available sources?

            This may include sources accessible upon subscription and/or payment

            Based on both publicly available and restricted-access sources

            Is the full model database as such available to external users?

            Whether or not it implies a specific procedure or a fee

            no
            The main dataset used to calibrate the model (with 2017 data) is publicly available.

            Have model results been presented in publicly available reports?

            Note this excludes IA reports.

            yes

            Have output datasets been made publicly available?

            Note this could also imply a specific procedure or a fee.

            no
            Model outputs are publicly available through the publications made by the members of the TEDAM team. Full results are available upon request.

              Is there any user friendly interface presenting model results that is accessible to the public?

              For instance: Dashboard, interactive interfaces...

              yes

              Has the model been documented in a publicly available dedicated report or a manual?

              Note this excludes IA reports.

              yes
              All the model equations are transparently documented in Salotti et al. (2025) and other recent articles.

              Is there a dedicated public website where information about the model is provided?

              yes

              Is the model code open-source?

              no

              Can the code be accessed upon request?

              no
