"When does specification or aggregation matter for model simulation outcomes? An investigation into demand systems"
by Boysen, Ole


Abstract
Economic impact analysis simulation models frequently rely on some kind of representation of consumption behavior. However, the sensitivity of such results with respect to the choices of the specification and the level of aggregation across consumers has not yet been thoroughly examined. We exploit a unique dataset to simulate various stereotypical scenarios and investigate the influence of the choice between five demand system specifications and household-level versus national-level models on several outcome measures. We find that both choices have a large influence on simulation results and thus on policies deduced therefrom. Our results point to pragmatic recommendations for various settings.
