Outline of Final Research Achievements

The research has derived the following two results.
[1] Bundling by an infrastructure incumbent can preserve its monopoly position by hindering an entrant's information acquisition. Furthermore, such a practice of bundling that prevents information acquisition deteriorates social welfare.
[2] Firms' incentive to invest for product quality improvement in a joint infrastructure deployment mode is weaker than that in an independent deployment mode. As a result, joint infrastructure deployment can be excessive from a social viewpoint, especially when firms have a strategic opportunity to invest for product quality improvement.

Academic Significance and Societal Importance of the Research Achievements

本研究では、複数市場モデルと垂直二部門モデルの基本枠組を用いて多様な形態を持つ企業間での競争に注目する。市場融合を反映した複数市場モデルの枠組では、一括販売戦略や複数市場にまたがる企業間提携など企業戦略も多様化する。複数市場モデルの分析は、企業戦略の拡張や需要の相互依存関係を通じて、規制政策の設計に必要な新たな要因を加える。
垂直二部門モデルに注目する理由は、小売部門では短期戦略、卸売部門ではインフラ投資などの長期戦略が重要だからである。インフラ産業における規制・競争政策に関する経済厚生上の評価を考える際、企業の長期的戦略誘因の効果を明示的に分析しなければならない。
