We consider the research and development (R&D) investment com petition of duopolistic firms in completely complementary technologies. By "completely complementary technologies," we mean that no firm can produce the goods without both of the technologies. We derive the investments competition...

We consider research and development (R&D) investment competition between duopolistic firms that independently invest in two complementary technologies to produce their products. By "partially complementary technologies", we mean that each firm can produce the goods without both technologies but...

This paper examines how parallel importation influences pharmaceutical innovation and the welfare of the economy, when crossnational drug price differentials occur not only because of demand elasticity based factors, but also governmental drug price control based factors. By explicitly...

This paper provides a simple model that examines a firmfs incentive to invest in a network infrastructure through coalition formation in an open access environment with a deregulated retail market. A regulator faces a dilemma between inducing an incentive for efficient investment and reducing...

In this paper, we analyze the managerial behavior of firms by estimating a nested objective function consistent with the framework of Fershtman and Judd (1987). Using data for Japanese regional banks for FY 1980-FY 2009, we focus on oligopolistic behavior in the domestic loan market and examine...

We examine an effect of limited liability on strategic delegation in a Cournot duopoly with demand uncertainty. We establish that owners of each firm always delegate their tasks, decisions, and responsibility to a manager under limited liability, while they do not always do so under unlimited...

We formulate a three-stage game in which a Japanese firm as a generalized labor-managed firm and an American firm as a profit-maximizing firm compete in the homogeneous product market. In the first stage of the game, both the firms decide whether they enter the market or not. In the second...

We examine the relationship between the objective of a monopolist and limited liability. We establish that the owners of a monopolistic firm are better off to choose profit maximization rather than sales maximization under both unlimited and limited liability. This is consistent with the fact...

We address the following question: Why do most large firms select limited liability as their business organizational form in the real world? We construct a two-stage game. In the first stage, each of the oligopolistic firms chooses its business organizational form, while in the second stage,...

This paper constructs a simple Malthusian model to explain per capita income differences in the Malthusian era by focusing on regional variations in the expansion of the commercial sector. This paper shows that a larger productivity improvement in the skilled intensive commercial sector relative...
