Key research themes
1. How does imperfect competition affect efficiency and economic freedom in oligopolistic markets?
This research area investigates the normative and economic foundations of imperfect competition, particularly how economic freedom and efficiency interact in markets characterized by oligopoly and other imperfect market structures. It addresses the trade-offs and complementarities between individual liberty in economic decisions and overall social welfare, revisiting classical economic philosophy in light of modern antitrust and regulatory debates.
2. What are the equilibrium characteristics and stability conditions in oligopolistic markets with differentiated products and strategic expectations?
This theme centers on the formal modeling of oligopoly equilibria when firms compete in quantity or price with product differentiation and strategic expectations about rivals’ behaviors. It critically extends classical Cournot and Bertrand frameworks to incorporate realistic market features such as partial product differentiation, coalition formation, asymmetric cost structures, and dynamic strategic responses, with applications in telecom and other industries.
3. How do strategic firm choices in internal organization and financing interact under imperfect competition?
This theme addresses the interplay between firms’ financial structure (debt financing) and internal organizational incentives (managerial delegation) in oligopolistic contexts with quantity or price competition. It systematically investigates whether these strategic choices are substitutes or complements and elucidates how such decisions affect competitive behavior and firm performance in imperfectly competitive markets.
