    2021年度は以下の3つの研究テーマを柱として研究を進めた。
    1.昨年度に引き続き、Klibanoff et al. (2005, Econometrica)のモデルに基づき、曖昧性への態度が、意思決定者の投資行動にどのような影響を与えるかについて分析を行った。効用関数を使った通常のモデルでは、一変数による分析を行うことが多いが、二変数以上の分析を考慮した方がより相応しい場合が多い。例えば、人々の将来の効用を分析する場合、将来の金融資産に加えて、将来の健康状態を分析に加えた方がより現実的である。本研究では、二つの確率変数をモデルに取り込んだ上で、二つの確率変数に相関がある場合、相関の存在が人々の最適投資にどのような影響を与えるかについて、曖昧性のもとで分析を行った。さらに、確率優位の概念をモデルに取り込み、最適投資に与える影響を分析した。本研究は、Discussion Paperとして公刊し、国際的学術誌に投稿・審査中である。2. belief functionの公理化に関する研究を進展させ、人々のbeliefがbelief functionで表現され、人々のpreferenceがそれに関するChoquet積分で表現されることを証明し、国際的学術誌に投稿した。3. Chateaunef et al. (2007) が提唱したneo-additive CEUについて、新たな視点から公理化を行った。この研究は、uncertainty lovingとuncertainty averse に関連付ける公理群と、確実性等価に関連付ける公理群という、二つの公理群を発見し、この選好の新しい経済学的な意味付けを与えた。2021年度中に完成・投稿することは出来なかったが、2022年度の早い時期に国際的学術誌に投稿する予定である。

    2020年-2022年度の研究計画に基づき、以下のような研究を行った。 1.Asano and Kojima (2021) を国際的学術誌に投稿した。この論文はShaferタイプのbelief functionを特徴づける数学理論であり、確実性等価概念のナイト流不確実性理論への拡張に対応するものである。医療サービスは人々の生命やQOLに関わるため、通常の財・サービスとは異なる性質を持っている。したがって、医療サービスへの選好は、ナイト流不確実性に属するものと言える。この論文は、医療サービスの制度設計の評価に関して、一つの基準を与える礎となり得る。2. 2021年8月に日本細胞移植学会にて、研究責任者が「社会的共通資本としての医療について」と題する基調講演を行った。これは、宇沢弘文の提唱した「社会的共通資本の理論」を医療サービスに応用する方向性を示す講演である。とりわけ、研究責任者が本事業で研究を進めている「医療ベース資本主義」の構想を医師たちに向けて発信する重要な機会となったことを特記する。3. Asano and Kojima (2021)の応用として、Chateauneuf et al.(2007)が提唱したNeo-additive capacityの別証明を完成した。この選好は、極端な結果に強い反応を示す選好であり、医療サービスに関する人々の行動を説明できる。我々はこの選好を、uncertainty lovingとuncertainty averse に関連付ける公理群と、確実性等価に関連付ける公理群という、二つの公理群を発見し、この選好の新しい経済学的な意味付けを与えたと評価できる。論文はほぼ完成しており、国際的学術誌に近日中に投稿する。

    The main results of this research project are twofold.
    1. We axiomatize the three updating rules (Dempster-Shafer, Naive Bayes, and Fagin-Halpern updating rules) under consequentialism and some kinds of dynamic consistency.
    2. We characterize the Choquet integral with respect to belief functions and directly derive belief functions on a state space.

    There are intrinsic information asymmetries in in financial markets, which disturb the functioning of the markets. In this project, we took into account such capital market imperfections and analyzed many macroeconomic issues. First, we showed that the existence of capital market imperfections can be a source of bubbles and a destabilizing factor in the economy. We also provided analyses of effective macroeconomic policies under these circumstances. We also introduced shocks that do not allow us to know the probability distribution in advance (Knightian uncertainty), and analyzed how the existence of uncertainty affects the dynamic behavior of various agents. We focused on the role of institutions such as education and investigated macroeconomic implications of institutions.

    We pay attention to the relationship of both technology and market competition among firms, and then to focus on international trade, foreign direct investment, and international activities of firms and their global developments as main subjects of investigation. The purpose of our research is to consider the dynamics of foreign production and supply activities of firms. We had analyzed the following topics from empirical and theoretical aspects: (1) Analysis of a competitive relationship between technology and good markets; (2) analysis of a relationship between a form of firm ownership and its innovation and globalization strategies; (3) analysis of global production activities of firms under Knightian uncertainty; (4) analysis of impacts of regional trade agreements on a competitive relationship among firms and innovation; and (5) analysis of dynamics of international production and supply activities of firms.

    1. I axiomatize the three updating rules under consequentialism and dynamic consistency.
    2. I consider a portfolio allocation problem between a risky asset and an ambiguous asset, and investigates how the existence of ambiguity influences the optimal proportion invested in the two assets. By introducing the notion of ambiguity, we derive several sufficient conditions under which an investor decreases the optimal proportion invested in the ambiguous asset.

    Following the world financial crisis and the eastern Japan great earthquake, this project, by means of theoretical and empirical analyses as well as data building, has studied the processes in which an economic crisis forms and is overcome. A major theoretical contribution is to demonstrate that even if the market is well functioning, it is natural that an extreme crisis occurs once in a while due to the interaction between innovation and market quality and that the recovery process after a crisis can be crucially influenced by the market infrastructure formed during and soon after the crisis. We have also obtained several important empirical results by building original data. The main results include the following: Japanese unconventional monetary policy after the financial crisis may have created strong noises that reduced financial market quality and delayed the recovery. It is important to raise the quality of insurance markets for natural disasters, including earthquakes, in order to equalize social costs of potential disasters across various regions.

    In this research project, we investigate money holdings under recessions using Knightian uncertainty that is wider notion than probabilistic risk.

    Grant amount:\8450000 ( Direct expense: \6500000 、 Indirect expense:\1950000 )

    The main results obtained in this project are summarized as follows
    (1) Constructing a dynamic general equilibrium model with financial market imperfections, we showed that the development of financial market in an economy could destabilize the economy.
    (2) Using Japanese firm level data, we showed that until the mid of 1990s firms' financing methods such as corporate borrowings from banks, bonds and trade credits were strongly substitutable to liquid asset holdings in both the manufacturing and non-manufacturing sectors and that this relationship was weakened in the late 1990s.
    (3) Introducing Knightian uncertainty into two-period models, we showed that the degree of Knightian uncertainty affects various kinds of investment behavior and that the direction of the effects of Knightian uncertainty depends on the nature of the uncertainty.
    (4) Constructing an overlapping generations model with financial market frictions, we showed that in the presence of credit constraints asset bubbles can emerge even in a dynamically efficient economy and that these bubbles can destabilize the economy.
