The International Input-Output Association (IIOA) is a non-profit, scientific organisation founded in 1988. The IIOA today is a thriving, growing and influential organisation with 1009 members spanning 66 countries. The objective of the IIOA is the advancement of knowledge in the field of Input-Output data compilation and analysis, including improvements in basic data, theoretical insights and modelling, and applications - traditional and novel - of Input-Output techniques. The IIOA delivers its core objectives by supporting young scholars, widening the awareness of the organisation, providing exchange of experience through our global annual IIOA Conference. The global IIOA community brings together both producers (e.g. national statistical offices) of the statistics needed and the wide range of users, analysts and policy makers to advance knowledge on energy, environment, international trade, financial flows, price and general equilibrium analysis, ecological sustainability and well-being. We welcome you to browse through the IIOA webpages, contact one of our Council Members, and to attend our annual conferences to learn more of the IIOA and its activities. We also encourage you to become a Member of the IIOA by registering here. 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. News
