Organized by the TGU Center for Positive/Empirical Analysis of Political Economy, “the Pan Pacific Game Theory Conference“was held on March 9 and 10, 2019 at Waseda University. Now in its 11th year, this conference aims to stimulate discussions and debate among Asian, European and American researchers who are leading the field from all over and outside Japan. The conference allocates sufficient time for researchers to present new theories and basic research so that they can discuss them with participants. Many challenging topics were presented this year, and through cross-sectional discussions, the participants learned about the latest research outcomes.
On the first day of the conference, Professor Christian List from London School of Economics spoke about a new choice theory. Professor List proposed a new framework to obtain individuals’ preference relations instead of classical revealed preference theory. In his framework, individuals compare their actual choices with other alternatives in the contexts they face. Such comparison is characterized in their contexts and is regarded as an aspect of bounded rationality. Associate Professor Yukio Koriyama gave a presentation about voting theory which aggregates both individuals’ and groups’ preference. He formulated the situations that electoral voters are determined depending of states in incomplete information games and showed one of the equilibria is strategic dominance.
As other presenters, Associate Professor Yanjing Wang from Peking University proposed a new formulation of “knowing how”, and Associate Professor Jeffrey J. Kline from Queensland University gave a presentation about imperfect recall games. Furthermore, Waseda Associate Professor Ryuichiro Ishikawa formulated Deliberative democracy as dialogue games, and Mr. Shimoda, an undergraduate student at Waseda, gave a presentation about core in voting games.
At the end of the first day, a reception was held for faculty, graduate students, and students from Waseda. The students were able to continue their discussion on the conference topics with the researchers, allowing them to further deepen their understanding. It became a valuable opportunity for them to ask for advice on their research and learn about frontline research.
On the second day, Associate Professor Adam Dominiak from Virginia Polytechnic Institute & State University shared his research on expected utility theory with ambiguity under dynamic awareness. Professor Oliver Schulte from Simon Fraser University presented belief revision theory, and Associate Professor Takayuki Oishi showed characterization of voting game. Furthermore, Waseda Associate Professor Satoru Shimokawa reported reputation damage due to the Fukushima nuclear power plant accident. The report attracted lots of questions from all the audience and gave a nice opportunity to let foreign researchers know about the Great East Japan Earthquake. They shared the necessity for a new economic theory.
Lastly, Waseda Professor Mamoru Kaneko ended the conference with his presentation on expected utility theory using probability grids and incomparabilities.
