| 研究実績の概要 |
We have revised and published "The Power of Non-Superpowers," Tomoo Kikuchi and Shuige Liu (https://doi.org/10.48550/arXiv.2209.10206).The paper proposes a game-theoretic model to investigate how non-superpowers with heterogenous preferences and endowments shape the superpower competition for a sphere of influence. Two superpowers play a Stackelberg game by providing club goods.Their utility depends on non-superpowers who form coalitions to join a club in the presence of externality. The coalition formation, which depends on the characteristics of nonsuperpowers,influences the behavior of superpowers and thus the size of their clubs. Our data-based simulations of the subgame perfect equilbirum capture how the US-China competition depends on other countries.
We are working on "Does Foreign Equity Contribute to Economic Growth?" Tomoo Kikuchi, Satoshi Tobe, Duy Van Dang, and Quang Trung Nguyen.The paper constructs a panel dataset covering 56 countries from 1985 to 2017 and find a positive relationship between foreign equity investment and GDP growth with private investment being a mediator. The impact of foreign equity investmenton private investment peaks in two years before it fades out.

理由
1) We set out to model currency choices for international trade settlement. We obtained the basic theorectical and simulation results for "Trade Networks and Currency Choices" with Lien Thi Quynh Pham and we are currently finalzing a draft. 2) We set out to work on empirical projects on a) the patterns of portfolio investment, b) foreign equity and economic growth, c) the perfomance of overseas M&A activities by US companies. For a) and b) we have obtained the main results and are working to produce working papers on "Portfolio Investment Patterns in East Asia," with Changran Lee; "The Role of Tax Havens for Portfolio Investment of the US and China," with Xiaoyu Cheng; "Does Foreign Equity Contribute to Economic Growth?" with Duy Van Dang and Quang Trung Nguyen. For c) we are still doing our preliminary analysis on "The Exorbitant Privilege and Cross-border M&A," with Sinan Caner Yamak.3) We set to analyze the relationship between our theoretical and emprical results. We have not yet attempted to present all our results in a coherent way.
Overall, we are making progress according to our initial plan to produce both theoretical and empirical papers under the umbrella project "The Mechanism and Stability of Global Imbalances".
