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 over 630 members spanning 59 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.

Call for Papers IIOA Online Development Programme 2021


To give young researchers a chance to receive feedback on their papers in a year in which the IIOA had to cancel its international conference again, an online version of the Development Programme will be offered. This announcement presents the details of this event (which is part of the IIOA's Virtual Campaign). All IIOA members is invited to attend!

Details and Key Dates

  • All sessions will take place in the week of July 5 – July 9;
  • MS Teams will be the platform used;
  • Each session contains at most 3 presentations. Each speaker has 15 minutes for presentation, after which there will be 10 minutes for discussion. The total number of sessions in the program depends on the number of accepted papers, with a maximum of 10;
  • The composition of the sessions will be dependent on the time zones in which speakers are located and the topics of their papers;
  • Papers can only be presented by researchers who were born in 1980 or later (co-authors are allowed to be older);
  • Selection is based on submission of full papers, which have to be submitted by May 31 (23:59 Central European Time) at the latest through the COPASS system (copass.iioa.org). Late submissions will not be taken into consideration;
  • The organizers will decide on whether a paper meets the minimum standards for presentation. The paper should be sufficiently clear and interesting, to the extent that they would have a decent chance of yielding a Revise and Resubmit if submitted to a good international journal. If the number of submitted papers exceeds 30, the organizers will select the best papers. The outcomes of the selection process will be communicated to the authors by June 10 at the latest;
  • The full programme will be announced to all IIOA members by means of a mass mail message by June 18 at the latest. Links to the respective sessions will be included in this message;
  • The full programme will contain the e-mail addresses of speakers. Attendees are encouraged to request and read the papers before they are presented to maximize the number and quality of suggestions provided to the presenters. Attendees and speakers can also use the e-mail addresses to continue discussions after the sessions;
  • Participation (both for speakers and attendees) is free of charge for all IIOA-members.

We sincerely hope that young researchers will take this opportunity to present their work and to get feedback, despite the unfortunate circumstances they are currently experiencing. Please do not hesitate to contact us (b.los@rug.nl) if you would have questions or comments.

Best wishes and stay safe,
Rossella Bardazzi, Bart Los and Anne Owen (organizers)

(Randall Jackson)


Sir Richard Stone Prize is awarded every other year for the best paper(s) that was submitted and accepted for publication in IIOA's journal Economic Systems Research in the two consecutive volumes. The prize is donated by Francis & Taylor, the Publisher of the journal. (See https://www.iioa.org/who_we_are/fellows_and_prizes.html for the list of past awardees.)

This year, the jury has decided to award the prize to the following two papers of exceptional qualities. Congratulations !!


Yuwan Duan, Erik Dietzenbacher, Xuemei Jiang, Xikang Chen & Cuihong Yang (2018)
Why has China’s vertical specialization declined?

<Messages from awardees>

Yuwan Duan
Associate Professor,
School of International Trade and Economics, Central University of Finance and Economics
“We are overwhelmed with gratitude to have been selected to receive the Sir Richard Stone Prize. We are deeply honored. This award is a high degree of recognition of our paper, and also strengthens my confidence in devoting my rest of life to scientific research. I would like to express my sincere gratitude to those who helped us in this paper and my research career. I also hope that this recognition of our work can serve as an inspiration to others in the field. This paper examined the causes and implications of the decline in Chinese vertical specialization in recent years. We find that the substitution of imported intermediates with domestically produced intermediates was the main driver, which suggests an upgrade of China's role in the Goble Value Chain. However, if the study was for this year, then the COVID-19 should be the main culprit for the decline in global vertical production. Hope that we humans can eliminate the virus as soon as possible and wish that everyone will be able to ride out this epidemic safely and healthily.”


Yoshio Kajitani
Professor,
Faculty of Engineering and Design, Kagawa University
“We are very honored to receive the Sir Richard Stone Prize. The awarded paper is an outcome of long-term discussions not only between the authors but also with many experts of I-O and CGE modelling. Especially, a series of sessions on disaster impact analysis in the IIOA annual meetings gave us precious occasions to meet with the specialists in this field. We hope the paper replies to many of practical questions raised in the sessions, in applying interindustry types of modeling to natural disasters. Our special thanks are due to Profs/Drs. Stephanie Chang, Yasuhide Okuyama, Jan Oosterhaven, Adam Rose, Albert Steenge and many others for the discussions to our presentations and Prof. Michael Lahr and anonymous reviewers for constructive feedbacks and supports at the review process. We also greatly appreciate the encouragements and insightful comments from Prof. Geoffrey Hewings and Dr. Nori Yamano, and Prof. Norio Okada, who also gave us the chance to step in this research field (engineering-economics modeling) almost 20 years ago.
While appreciating many good lucks, we cannot help thinking that the Covid-19 is challenging us and changing economic systems. We strongly hope the evidence-based approach and economic impact modeling contribute to better policy making.”

Report: Online sessions for young researchers


(Bart Los)

Unfortunately, the International Input-Output Conference in Kuala Lumpur had to be postponed, due to the Covid-19 pandemic. To give young researchers an opportunity to present their work and to get some feedback on their current work, the IIOA Council decided to organize a small-scale online initiative in the first week of July (the week in which the conference would have taken place). Five sessions were held. The speakers and titles of their presentations can be found below.

The organizers (Satoshi Inomata, Shigemi Kagawa and Bart Los) sent out an invitation to all researchers who had submitted a paper to the Leontief Prize competition, wanted to be included in the Development Programme or had applied for IIOA travel grants. Of the 48 invited researchers, 18 accepted the invitation. To make sure that all presenters could attend without being deprived from sleep, the speakers were assigned to Oceania/Asia/Europe and Europe/Americas sessions (unfortunately, we did not have African speakers). The so-called ‘caretakers’ played a pivotal role in the organization: one speaker coordinated the date and the time of the session with the other speakers and made sure that an online videocalling platform would be used that would suit all speakers. The organizers then mass-mailed the IIOA-members to attend the sessions as members of the audience. In order to avoid unnecessary internet connection disruptions, the total number of participants per session was capped at eight. This created a cordial atmosphere, to the extent possible in an online setting. All sessions were full, although misinterpretations about the announced time zones caused a small number of latecomers (but this happens at physical conferences as well…). The caretakers had also ensured that all participants had been sent the slides and papers beforehand, to minimize the ‘damage’ in case of disruptions.

The sessions went well. The internet-related problems were very minor and the session caretakers all reported interaction between the presenters and members of the audience. As organizers we also learned a lot along the way. We received a number of useful suggestions for improvement. Nobody knows how we will gather in the future. Hopefully, it will be possible to organize physical meetings again. Still, it is likely that online events will remain an important element of our activities, so learning about ways to make these happen was helpful. The number 1 objective, however, was to support young researchers. We think this worked out well, to a large extent due to the activities of the session caretakers: Oliya Maxudova (Ritsumeikan Asia Pacific University), Carolina Silva Ribeiro (Federal University of Bahia), Eduardo Sanguinet (Pontifical Catholic University of Rio Grande do Sul/Catholic University of the North), Maksud Bechkanov (Bonn University) and Wannaphong Durongkaveroj (Australian National University).
