Outline of Final Research Achievements

The research project focused on the strategic behavior of firms facing multiple markets, with two main themes: 1. consumer behavior and firm strategies in markets at different points in time, and 2. multiple markets, including labor, financial, and common resource markets. The study conducted theoretical analyses on these themes.
The findings revealed the impact of various strategic behaviors on social welfare, such as free entry into markets, price collusion among firms, partial coalitions among agents with common resources, social interactions among workers in team production, and market competition between genuine and generic products.
During the research period, four working papers were published and submitted to international peer-reviewed journals. Additionally, two papers were published in international peer-reviewed journals, and three presentations were made at international conferences (with screening).

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は、複数市場に直面する企業の戦略的行動が社会厚生に与える影響を、異時点のマーケットや労働・金融・共有資源市場など多角的に分析し、市場への自由参入、価格共謀、共有資源での部分提携、チーム生産における社会的交流、純正品と汎用品の競争などに関する新たな理論的知見を提供した点にある。
また、現実の経済で観察される現象（価格共謀や参入阻止行動、国際環境協定や模倣・コピー品の市場）を対象とし、企業の戦略的行動が社会厚生に与える影響を明らかにするとともに、望ましい公的規制のあり方を検討した点で、本研究は経済政策立案に資する重要な社会的意義を持つと考えられる。
