This paper reviews the existing literature on modelling the macroeconomic consequences of the transition to a circular economy. It provides insights into the current state of the art on modelling policies to improve resource efficiency and the transition to a circular economy by examining 24 modelling-based assessments of a circular economy transition. Four key conclusions emerge from this literature. First, most models find that a transition to a more circular economy – with an associated reduction in resource extraction and waste generation – could have an insignificant or even positive impact on aggregate macroeconomic outcomes. Second, all models highlight the potential re-allocation effects – both between sectors and regions – of the introduction of circular economy policies.
