Input-Output

Course Objective The objective of the course is to discuss the relation of economic input-output models with graph theory and networks. The course is now live at the Academy. Pre-requisites Basic knowledge of input-output models and graph theory would help to get the most out of the course but is not strictly required. Summary of the Course What we cover in this course: Step 1. In this step we discuss in more detail the motivation for the course and provide a very brief introduction to the graph theory to establish the notation.

What are Input-Output Models? Environmentally Extended Multi-Regional Input-Output (EE-MRIO) tables describe economic relationships of economic actors (e.g. industrial sectors) operating within and between regions and their environmental repercussions. An EE MRIO augments the more basic and historically first proposed Input-Output Models (IO) with additional datasets and/or modeling assumptions in order to provide insights into the environmental foorprint of economic activity. Presently, the emphasis on negative externalities of economic activity (e.g., climate change, biodiversity loss) turns EE MRIO models into a useful conceptual and analytic tool.
