Economic interconnections: Hypothetical Extraction Method in Input-Output Analysis, 21 Nov, 13.00 CET
It has long been the desire of industrial ecologists to understand the interconnectedness of the economy. While methods such as production layer, structural path, and network analysis provide insights into individual trades, the systematic economy-wide interconnectedness requires different approaches. The Hypothetical Extraction Method (HEM), also called supply chain impact method within industrial ecology, is able to systematically investigate this interconnectedness. It can calculate how much of a product’s price or footprint is due to the input provided by specified other sectors, anywhere in the production network. It can determine how much of an industry’s inputs come from a specific production process, which is why it has been used for disaster impact analysis in regional economics. Here we provide a short introduction to the method and provide several examples of how it is used in ongoing research.
