This paper examines whether production efficiency is attained in a capitalistic class economy where complete contracts are not available. It is shown that such an economy often fails to achieve production efficiency.

The results on the design of incentive compatible mechanisms for implementing public decisions establish that there is no general solution to the incentive problem if the mechanisms are required to be informationally decentralized. However, even when the planner possesses the knowledge of the...

Employing an environmentally-differentiated products model with heterogeneous consumers in terms of environmental consciousness, this paper examines the effect of a unilateral change in a home emission standard on the qualities of products, aggregate emissions, and welfare of both home and...

Abstract This paper studies the optimal organizational form and the optimal type of manager by considering the nonmaterial (psychological) payoff as well as the standard material payoff for agents. I compare two organizational forms: T-form, where all agents have the same job title so that they...

Some firms may exhibit better operating performance than others because they undertake riskier projects: risk-return tradeoff. We develop a model to examine the effects of financial contracts on a firmfs choice between safer (lower risk, lower return) and riskier (higher risk, higher return)...

We provide a simple model of endogenous product compatibility choice under Cournot competition with a network externality. Using the model, we consider how the degree of a network externality and product substitutability affects the choice regarding product compatibility. In particular, if the...

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...

The Bank of Japan has used some unconventional monetary easing measures for more than a decade, and it is often pointed out that it might damage the Bank’s capital and thus jeopardize its credibility. First, this paper reviews the past literature on the role of central bank capital and how a...

We investigate a Stackelberg oligopoly model in which m leaders and N-m followers compete. We find an asymmetric welfare implication of the Stackelberg model. Introducing a small number of leaders into the Cournot model can reduce welfare. However, introducing a small number of followers into...

This paper constructs a simple, overlapping generations version of an R&D-based growth model à la Diamond (1965) and Jones (1995), and examines how an increase in old-age survival probability impacts purposeful R&D investment and long-run growth by affecting fertility and education decisions....
