Supply chain decoupling in green products: a granular input-output analysis
This paper introduces a novel methodology to enhance the granularity of Inter-Country Input-Output (ICIO) tables. While our general methodology can be applied to any products of interest, we show that the well-documented distortions caused by sectoral aggregation in ICIO tables are particularly pronounced for products with a low substitutability, such as those essential to the green transition (e.g. electric batteries, rare earths). We therefore apply our framework to construct a disaggregated ICIO table that singles out 129 products essential to the energy transition.
