The 23rd International Symposium on Econometrics, Operations Research and Statistics (EYI 2026) will be hosted by the Department of Econometrics, Faculty of Economics and Administrative Sciences, Manisa Celal Bayar University, and will take place on 17–19 September 2026 at the Prof. Dr. Ümit Doğay Arınç Cultural Center in Manisa, Türkiye.

The theme of this year’s symposium is “Econometrics at 100: A Century of Theory and Data.” This theme celebrates the intellectual evolution of econometrics over the past century and emphasizes the enduring interaction between theoretical reasoning and empirical evidence. Since its emergence in the early twentieth century, econometrics has played a crucial role in bridging economic theory with real-world data through rigorous statistical and quantitative methods. Today, with the rapid expansion of data science, artificial intelligence, and computational techniques, econometrics continues to provide essential tools for understanding complex economic and social phenomena.

The EYI Symposium has long served as a distinguished international forum that brings together researchers, academics, and professionals working in the fields of econometrics, operations research, statistics, and related quantitative disciplines. The symposium aims to promote the exchange of innovative ideas, present recent scientific developments, and foster collaboration among scholars from different countries and institutions.

The symposium program will include invited talks, plenary sessions, and parallel sessions, covering a wide range of topics related to theoretical developments, methodological advances, and empirical applications.

Participants presenting their papers on-site will have the opportunity to submit full papers for publication in the conference proceedings. Each accepted paper will be assigned a DOI, and the proceedings volumes will be published with an ISBN. In addition, selected papers will be invited for submission to special issues of academic journals.

We cordially invite researchers and practitioners to submit their original research and join us in this international scientific gathering. Your participation will contribute significantly to the intellectual exchange and the continued development of econometrics and related disciplines.

We look forward to welcoming you to Manisa in September 2026.
