This paper studies the relationship between horizontal product differentiation and the welfare effects of third-degree price discrimination in oligopoly. By deriving linear demand from a representative consumer's utility and focusing on the symmetric equilibrium of a pricing game, we...

We consider a downstream duopoly model with a monopolistic common supplier and mutual outsourcing between the two symmetric downstream firms. The market structure captures the recent procurement environment in the smartphone industry. We also incorporate managerial delegations into the duopoly...

This study investigates mixed markets in which a social welfare-maximizing public firm and a private firm engage in behavior-based price discrimination (BBPD). Total of two cases are considered: one where domestic shareholders completely own the private firm and one where foreign shareholders...

This study examines how consumers' personal data management affects firms' competition in the data collection and data application markets and welfare outcomes. Consumers purchase products from differentiated firms in two markets. Firms compete to collect consumer data first to predict their...

In a model of behavior-based price discrimination (BBPD), we argue that sellers may have discretionary power to let buyers decide whether to be identified (e.g., creating an account) or remain anonymous (no account creation). The price equilibria generate a more fragmented market segmentation...

We consider a downstream oligopoly model with one dominant and several fringe retailers who purchase a manufacturing product from a monopoly supplier. We examine how contract type influences the relationship between the dominant retailer's bargaining power and the equilibrium retail price. If...

The recent developments in information technology (IT) have enabled firms to employ personalized pricing. Should all firms employ personalized pricing even though the adaptation costs of such pricing strategies are not high? This paper theoretically demonstrates a situation in which all firms do...
