Collusion and research joint ventures
Miyagiwa, Kaz - 2007
We examine whether cooperation in R&D leads to product market collusion. Suppose that firms engage in a stochastic R … symmetries, thereby facilitating collusion. Sharing an efficient technology also increases industry profit, which contributes to … the collusion stability but also raises social welfare. Interestingly, a welfare improvement is less likely if innovation …

Product differentiation and entry timing in a continuous time spatial competition model
Ebina, Takeshi; Matsushima, Noriaki; Shimizu, Daisuke - 2014
We extend the well-known spatial competition model (d'Aspremont et al., 1979) to a continuous time model in which two firms compete in each instance. Our focus is on the entry timing decisions of firms and their optimal locations. We demonstrate that the leader has an incentive to locate closer...

Strategic dual sourcing as a driver for free revealing of innovation
Matsushima, Noriaki; Zhao, Laixun - 2015
This paper examines the role of dual sourcing (e.g., outside options) in vertical and horizontal relations. In a bilateral monopoly market, if either the upstream or downstream firm has outside options, the other firm could lose from seemingly positive shocks, e.g., market expansion or...

Scoring auctions with non-quasilinear scoring rules
Dastidar, Krishnendu Ghosh - 2014
In this paper we analyse scoring auctions with general non-quasilinear scoring rules. We assume that cost function of each firm is additively separable in quality and type. In sharp contrast to the recent results in the literature we show the following. (i) Equilibria in scoring auctions can be...

One-leader and multiple-follower Stackelberg games with private information
Nakamura, Tomoya - 2014
This study analyzes one-leader and multiple-follower Stackelberg games with private information regarding demand uncertainty. In the equilibrium of the Stackelberg games, a leader's private information becomes public information among followers. This study demonstrates that the strategic...

Does self-regulation of advertisement length improve consumer welfare?
Matsubae, Taisuke; Matsushima, Noriaki - 2012
In Japan, TV platforms regulate themselves as to the length of the advertisements they air. Using modified Hotelling models, we investigate whether such self-regulation improves consumer and social welfare or not. When all consumers choose a single TV program (the utility functions of consumers...

Vertical separation as a defense against strong suppliers
Matsushima, Noriaki; Mizuno, Tomomichi - 2009
We provide a simple model to investigate decisions about vertical separation. The key feature of this model is that more than one input is required for the final product of the downstream monopolist. We show that as the bargaining powers of independent complementary input suppliers grow larger,...

Matsumura, Toshihiro; Matsushima, Noriaki - 2013
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...
