Welcome to the IIOA Webinar CornerIntroductionThe IIOA introduced a series of webinars as one of the responses to the COVID-19 pandemic and the cancellation of the 2020 and 2021 annual IIOA Conferences. The aims of these webinars include:
• sharing information, research, developments and analyses; Topics can be of any nature relating to Input-Output and the presenters from within the IIOA community or beyond. BackgroundThe ground work laid out by Douglas Meade, Bart Los and Sanjiv Mahajan led to the introduction of the Webinar Programme Series in 2021 with Maureen Rimmer being the first presenter. As of 2022, Kuishuang Feng, a Member of the IIOA Council, is the new lead for the Webinar Programme Series, supported and advised by Sanjiv Mahajan. Notification of webinar(s)As and when a new webinar is available, this webpage will be updated and all IIOA Members will also be notified via email. Nearer the event date, final details will be circulated and a link to the webinar will be provided. No registration or payment is needed. Forthcoming webinarPresenter: Meng Li Date and time: Wed, 14-Jan-2026 13:00(CET) Dear Valued IIOA Member, We are pleased to welcome you to the upcoming 19th IIOA Webinar scheduled on Wednesday, 14th Jan 2026, at 1pm-2pm CET. We would like to extend our gratitude to Dr Meng Li for joining this webinar entitled “– Measuring Global Value Chains: Different Indices and Methods. Dr Meng Li was awarded the Leontief Memorial Prize in 2025. Meng Li is an Associate Professor at the School of Environmental Science and Engineering, Shanghai Jiao Tong University. Her research mainly focuses on input-output modeling, global supply/value chains, and their socio-economic, environmental, and climate impacts. Meng Li has led two projects funded by the National Natural Science Foundation of China. She has published research articles in journals such as Nature Communications, One Earth, and the Journal of Human Resources. TOPIC Title: Measuring Global Value Chains: Different Indices and Methods. Abstract: Understanding Global Value Chains (GVCs) is essential for analyzing the complex structure of modern international trade and production. This webinair will focus on providing a comprehensive overview of the various indices used to measure and characterize GVCs, including upstreamness, downstreamness, average propagation length, value-added decomposition, as well as integrating these indices within a probability framework. This webinair will discuss the decomposition techniques based on input-output analysis, which allow for the detailed tracing of value creation and transfer across countries and sectors. In addition, it will introduce Markov chain and probability-based methods for modeling the evolution and dynamics of global value chains, providing new insights into the stochastic nature of production network transformations. Special attention is devoted to the propagation of risks and shocks through global value chains and global production networks, highlighting how disturbances in one part of the system can have far-reaching impacts. This webinair aims to provide a methodological toolkit for researchers and policymakers seeking to analyze and manage the resilience and sustainability of global production systems.
