We examine whether cooperation in R&D leads to product market collusion. Suppose that firms engage in a stochastic R&D race while maintaining the collusive equilibrium in a repeated-game framework. Innovation under competitive R&D creates inter-firm asymmetries, which destabilizes the collusive...

We analyze firms' decisions to adopt a vertical integrated or decentralized structure taking into account the characteristics of both the final good competition and the R&D process. We consider two vertical chains, where R&D is conducted by upstream sectors. R&D investment determines the...

This paper studies the effects of 'price-matching' policies in the Bertrand oligopoly model. If one or more consumers incur enforcement costs to utilize price-matching clauses, the unique equilibrium outcome is the competitive one.

This paper considers an incumbent firm that is faced with a potential entrant in a vertically differentiated market. It demonstrates than an incumbent firm cannot prevent entry through product proliferation because of a commitment problem.

We provide a simple model to investigate decisions on vertical integration/separation. The key feature of this model is that more than one input is required for the final products of the local downstream monopolists. Depending on their cost structure, downstream firms' decisions on vertical...

The shock to the global economy from COVID-19 is predicted to be faster and more severe than the 2008 global financial crisis and even the Great Depression. We assess its impact on global fossil fuel consumption and CO2 emissions over a two-year horizon. For this purpose we employ a global...

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...

Personalized pricing has become a reality through digitization. We examine firms' incentives to adopt one of the three pricing schemes: uniform, personalized, or group pricing in a Hotelling duopoly model. There are two types of consumer groups that are heterogeneous in their mismatch costs. We...

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...
