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...

This paper examines the relationship between firms' productivity improvement and the volume of exports, and shows that it can be sometimes negative. Specifically, we simultaneously take into account intermediate retailers (i.e., vertically) and multimarket linkages (i.e., horizontally). We find...

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...

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...

This study constructs a model of anticompetitive exclusive contracts in the presence of complementary inputs. A downstream firm transforms multiple complementary inputs into final products. When complementary input suppliers have market power, upstream competition within a given input market...

We examine a monopolistic supplier's decision about a pure public good when he/she must negotiate with beneficiaries of the good. In our model, while the level of the public good is decided unilaterally by the supplier, the cost share of the public good is negotiated between the supplier and...

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...

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,...

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...

We investigate a Cournot model with strategic R&D investments wherein efficient low-cost firms compete against less efficient high-cost firms. We find that an increase in the number of high-cost firms can stimulate R&D by the low-cost firms, while it always reduces R&D by the high-cost firms....
