Capital stranding cascades: The impact of decarbonisation on productive asset utilisation
研究脱碳过程中化石燃料减产如何通过国际生产网络引发其他行业资本利用不足，提出“搁浅乘数”衡量风险，并评估各国暴露程度。
A timely low-carbon transition will require a significant decline in fossil fuel production and consumption. This in turn exposes the rest of economic sectors to the risk of reduced usability of physical capital stocks via international production network linkages. We propose and apply a simple measure to assess the extent to which fossil shocks might trigger underutilisation of capital stocks across countries and productive sectors (‘stranding multipliers’). Our results highlight the relevance of supply-side transition risks. First, among all productive activities, the global fossil sector exhibits the highest stranding multiplier on the rest of the economic system. Second, some of the most exposed sectors are downstream activities, mainly affected by second-round effects. Third, we rank countries according to their external stranding potential, finding France, Australia and Slovakia at the top, and the USA, Italy and China at its bottom. Finally, we rank countries according to their exposure to stranding risk and analyse more in depth the origins and transmission channels of the stranding links affecting some of the most exposed countries (USA, China and Germany).
