| Outline of Final Research Achievements |
We investigated the effects of investment information disclosure on firms’ decision and social welfare in a single Cournot competition, a vertically related industry, and multiple markets, respectively. We reported our results in two academic conferences and wrote 4 papers. All papers were submitted to international academic journals, and two papers are under peer review. We will resubmit rejected papers in 2020 after revised.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，3つの製品市場(①単一の製品市場，②川上企業が存在する垂直市場，③複数の製品市場)を想定したうえで，既存研究が考慮してこなかった3つの要因(報酬契約といったガバナンス情報，川下企業の開示戦略，市場間開示環境)を考慮し，情報開示の影響について分析した。特に，情報を開示することが企業利得や社会厚生を阻害する状況について明らかにすることで，開示規制の有用性について重要な情報を提供した。
