  • What Do Contracts Do to Facilitate Relationships?

    Hideshi Itoh

    The Japanese Economic Review   74 ( 3 ) 333 - 354  2023.07  [Refereed]  [Invited]  [International journal]

    　View Summary

    Abstract

    I demonstrate that transacting parties may expend resources on ex ante contracting, which may not be legally enforceable, to help build and maintain their long-term relationships. I first introduce three legal concepts, namely scaffolding, managerial provisions, and formal relational contracts, which highlight the recent trend towards more detailed contracts. These concepts indicate that the role of detailed contracts is not to improve judicial contract enforcement, but to enhance clarity and alignment of interests and to reduce renegotiation costs, which ultimately support the parties’ relationships. I then proceed to present and analyze a simple reduced-form model, which demonstrates that the parties’ efforts for ex ante contracting are not necessarily monotonic with the level of alignment of their interests. Furthermore, I discuss recent contracting practices in Japan and attempt to provide an explanation for the lack of change observed in these practices.

  • Information Acquisition, Decision Making, and Implementation in Organizations

    Hideshi Itoh, Kimiyuki Morita

    Management Science   69 ( 1 ) 446 - 463  2023.01  [Refereed]  [International journal]

    　View Summary

    We study the value of divergence in values and preferences in organizations by combining three stages of a decision process—ex ante information acquisition, interim project choice, and ex post project execution—into a tractable model. A key insight is that our unified model provides predictions different from models without the execution decision stage. We consider an organization that consists of a decision maker who selects a project and an implementer who acquires costly information before project choice and executes the selected project. They have intrinsic and possibly divergent preferences over projects. We show that, although the implementer’s dual role generates a disadvantage of designing conflicts in terms of the implementation motivation, it simultaneously boosts the implementer’s motivation for information acquisition to influence the decision maker’s project choice more under divergent preferences. Our results provide managerial insights that designing conflicts is beneficial only in environments where additional information is sufficiently precise and must be accompanied by a manager who is balanced and incorporating feedback.

  • Formal Contracts, Relational Contracts, and the Threat-Point Effect

    Hideshi Itoh, Hodaka Morita

    AMERICAN ECONOMIC JOURNAL-MICROECONOMICS   7 ( 3 ) 318 - 346  2015.08  [Refereed]

    　View Summary

    We investigate whether formal contracts can help in resolving the holdup problem by studying repeated transactions between a seller and a buyer. Contrary to previous findings, we demonstrate that a simple fixed-price contract based on product delivery is of value even when relation-specific investment is purely cooperative. Furthermore, we show that focusing our attention on fixed-price contracts as a form of formal contracts is without loss of generality. The key driving force is a possibility that the relation-specific investment decreases the surplus under no trade. This possibility, although very plausible, has been largely ignored in previous analyses of the holdup problem.

  • Complementarities among authority, accountability, and monitoring: Evidence from Japanese business groups

    Hideshi Itoh, Tatsuya Kikutani, Osamu Hayashida

    JOURNAL OF THE JAPANESE AND INTERNATIONAL ECONOMIES   22 ( 2 ) 207 - 228  2008.06  [Refereed]

    　View Summary

    This paper offers an empirical test of complementarities among delegated authority, accountability, and monitoring, using unique survey data collected from group-affiliated companies in Japan. The survey provides information about how various decisions are made within business groups, each of which consists of a large core parent firm and its network of affiliated firms such as subsidiaries and related companies. We find some evidence that delegated authority and accountability are complementary, implying that increasing assigned accountability raises the marginal return from increasing delegated authority. We also obtain a stronger result that performance is likely to be better under the combination of low authority and low accountability or that of high authority and high accountability than under the "mix and match" combinations where one is low and the other high. We then study the effects of monitoring intensity on the authority-accountability pair and find that performance of the firm with the combination of high authority and high accountability is increasing in monitoring intensity, while the combination of low authority and low accountability is not. This result is consistent with the theoretical hypothesis that increasing monitoring intensity raises the marginal return from increasing delegated authority and accountability.

  • Moral hazard and other-regarding preferences

    H Itoh

    JAPANESE ECONOMIC REVIEW   55 ( 1 ) 18 - 45  2004.03  [Refereed]  [Invited]

    　View Summary

    The paper aims at obtaining new theoretical insights by combining the standard moral hazard models of principal-agent relationships with theories of other-regarding preferences, in particular inequity aversion theory. The principal is in general worse off, as the agent cares more about the wellbeing of the principal. When there are multiple symmetric agents who care about each other's wellbeing, the principal can optimally exploit their other-regarding nature by designing an appropriate interdependent contract such as a "fair" team contract or a relative performance contract. The approach taken in this paper can shed light on issues on endogenous preferences within organizations.

  • Corporate restructuring in Japan Part I: Can M-form organization manage diverse businesses?

    H Itoh

    JAPANESE ECONOMIC REVIEW   54 ( 1 ) 49 - 73  2003.03  [Refereed]  [Invited]

    　View Summary

    The purpose of this paper is to examine the recent organizational restructuring in Japan in the framework of organizational economics, assuming that the product/market portfolio of the firm is fixed. How does a firm set about organizing its internal divisions? I first summarize some stylized facts on corporate diversification strategy and multi-divisional (M-form) organization in large Japanese firms from different perspectives. I then analyse the problem of,choosing an organizational form. In particular, I argue that, precisely because of its related diversification, the multi-business Japanese firm adopting the M-form finds it difficult to differentiate its diverse businesses internally.

  • Moral hazard and renegotiation with multiple agents

    S Ishiguro, H Itoh

    REVIEW OF ECONOMIC STUDIES   68 ( 1 ) 1 - 20  2001.01  [Refereed]

    　View Summary

    We investigate the effects of contract renegotiation in multi-agent situations where risk-averse agents negotiate a contract offer to the principal after the agents observe a common, unverifiable perfect signal about their actions. We show that renegotiation with multiple agents reduces the cost of implementing any implementable action profile down to the first best level, even though the principal cannot observe the agents' actions. Moreover, it is sufficient for the principal to use a "simple" initial contract, in the sense that it consists of no more than a single sharing scheme for each agent and the total payments to the agents are the same regardless of the realised state. An important implication is that decentralization, in the sense of delegated negotiation and proposals from the agents, can be as effective as centralized schemes that utilize revelation mechanisms in unrestricted ways.

  • JOB DESIGN, DELEGATION AND COOPERATION - A PRINCIPAL-AGENT ANALYSIS

    H ITOH

    EUROPEAN ECONOMIC REVIEW   38 ( 3-4 ) 691 - 700  1994.04  [Refereed]  [Invited]

    　View Summary

    This paper analyzes how tasks are assigned in organizations. Tasks can be allocated vertically between a principal and an agent, or laterally among agents. The resulting organizational job design determines how many tasks are delegated to agents, and how the agents' tasks are divided among them. In the framework of the standard principal-agent relationship with moral hazard, it is shown that (i) an incentive consideration causes the principal to group a broad range of tasks into an agent's job rather than hire multiple agents and make each of them specialize in just one task; and (ii) the principal may choose to delegate all the tasks in order to mitigate a conflicting incentive problem with agents.

  • Coalitions, Incentives, and Risk Sharing

    H ITOH

    JOURNAL OF ECONOMIC THEORY   60 ( 2 ) 410 - 427  1993.08  [Refereed]  [International journal]

    　View Summary

    This paper analyzes the effects of coalitional behavior in principal–multiagent relationships with moral hazard and identifies cases where the principal prefers agents to form a coalition via side contracting. It is shown that the principal can implement given efforts, via non-individualistic incentive contracts, at a lower cost when the agents can monitor each other′s efforts perfectly and hence coordinate their effort choice than when the agents behave independently. Permitting the principal to utilize more complex communication mechanisms does not alter the result, for there is no coalition-proof revelation mechanism improving the principal′s welfare.

    H ITOH

    ECONOMETRICA   59 ( 3 ) 611 - 636  1991.05  [Refereed]  [International journal]

    　View Summary

    This paper concerns moral hazard problems in multi-agent situations where cooperation is an issue. Each agent chooses his own effort, which improves stochastically the outcome of his own task. He also chooses the amount of "help" to extend to other agents, which improves their performance. By selecting appropriate compensation schemes, the principal can design a task structure: the principal may prefer an unambiguous division of labor, where each agent specializes in his own tasks; or the principal may prefer teamwork where each agent is motivated to help other agents. We provide a sufficient condition for teamwork to be optimal, based on its incentive effects. We also show a nonconvexity of the optimal task structure: The principal wants either an unambiguous division of labor or a substantial teamwork.

    　View Summary

    We analyze the informational structure of a one-top and one-subordinate organization of the firm facing an uncertain environment. Before the realization of the true state, the top manager must choose the information processing capacity of the subordinate, which is an ability to discern the local aspect of the environment and depends upon the global aspect of the environment observed by the top manager. We examine how uncertainty in the environment affects the degree of specialization in the optimal capacity and the amount of knowledge resources in the firm, and discuss its implications for comparisons between Japanese management and American management.

  • Contract Theory : Path toward the Third Theory of Microeconomics

    伊藤秀史

    経済学史研究   49 ( 2 ) 52 - 62  2007  [Invited]

    　View Summary

    The purpose of this article is to offer an overview of contract theory, a highly successful and active research area in microeconomics, with particular emphasis on its history and influence on modern economics. According to Bolton and Dewatripont (2005), currently a standard textbook in this field, the theory of incentives, information, and economic institutions is generally referred to in short as contract theory. Contract theory is thus a theory of imperfect markets, mainly because of asymmetric information such as moral hazard and adverse selection. Contract theory is also a theory of economic institutions and as such applies far beyond markets. The basic model of moral hazard and that of adverse selection both use agency (or principal-agent) relationships as the main analytical framework, in response to various attempts to lay open the black-box nature of the firm in the standard neoclassical model. Furthermore, theories of boundaries of the firm, originating out of Coase's classical work, are today analyzed in the framework of incomplete contracts that leads to the third basic model of contract theory, along with those of moral hazard and adverse selection. Although these basic models are games with specific extensive forms, they are formulated as optimization problems subject to incentive compatibility and participation conditions, and are solved without explicit reference to equilibrium concepts. Contract theory is thus related to both price theory and game theory, but it has developed its own analytical frameworks and tools to solve problems under conditions of asymmetric information or incomplete contracts. Contract theory is also a theory of incentive design. Incentive design is not important under perfect competition but is crucial when there is asymmetric information or contractual incompleteness. Myerson claims that today, "economists can define their field more broadly, as being about the analysis of incentives in all social institutions." (Myerson 1999) I argue that it is contract theory that enables us to define today's field more broadly.

    　View Summary

    We explored the importance and the role of experimental approaches in social sciences from diverse and broad viewpoints. First, we succeeded in clarifying the relationship between many different concepts in different fields of sciences: e.g. law and social norm in ethics and legal philosophy, institutions to foster efficient society in economics theory, mechanisms for the evolution of cooperation in evolutionary biology, and the physchological mechanisms identified in brain sciences. Second, many game theory models have been developed to understand diverse aspects and mechanisms to foster the cooperation among people. Finally the demogracy can be viewed as "social experiments" in which tries and errors were performed.

    We attempted to establish a system with which we monitor the real time Japanese economy both quickly and precisely and utilize it for an appropriate policy management. More concretely we conducted positive analyses of the Japanese economy from the view point of business cycle phase judgment and, based on the historical path of economic institutions, we also studied a possibility of medium-to long-term improvement of economic performances by activating technological innovations and altering the industry structure. We also pursued theoretical investigations of the business cycle mechanism and developed new statistical and econometrical models.

    　View Summary

    In this research I attempt to obtain new theoretical insights by combining the standard moral hazard models of principal-agent relationships with theories of other-regarding (inequity averse or status-seeking) preferences, that are consistent with many experimental results. In the benchmark principal-agent model, the principal and the agent are both risk neutral, while the agent is wealth constrained, and hence the basic tradeoff between incentives and rent extraction arises. I show that other-regarding preferences interact with incentives in nontrivial ways. In particular, the principal is in general worse off as the agent cares more about the well-being of the principal. I then extend the analysis to a multi-agent setting. When each agent cares about the well-being of the other agent, either a team contract or a relative performance contract is optimal even though there is no technological externality nor correlation. The extreme team contract is "fair" and more likely to be optimal as actions become mutually observable. However, team contracts are never optimal when the agents are competitive or status-seeking. I also show that the information structure also affects the optimal contract. Another important result I obtain is that the optimal contract for self-interest agents changes drastically when a small degree of other-regarding preferences is introduced. Under the technological assumption of the model, if the agents are self-interested, there is an optimal independent contract in which the payment scheme for each agent depends only on the outcome of his project. However, when the agents become other-regarding, however small the changes are, no independent contract is optimal any longer and the optimal contract is generically unique.

  • Comparative Study of Hiving Off Strategy and the Delegation of Authority

    　View Summary

    1. Making a Commitment Model of Delegation : Separating of an operating division from the main corporate body, called "hiving off", is an important organizational strategy. Why do companies take such a strategy? Why can not the same benefits as the case of hiving off be achieved within the existing organization, such as by adding a new business division? We regard it as a device for a corporation to commit herself to the delegation of authority to its subsidiaries or affiliates. We therefore made a commitment model of delegation to which the theory of incomplete contract was applied.
    2. Empirical Analysis of the Theory of Incomplete Contract : We conducted empirical analysis of the commitment model using probit statistical model with questionnaire data. At that time we adopted the method of comparing it to an alternative agency model. As a result of it, the commitment model was mostly supported.
    3. Interview of Foreign Corporations in Japan : It gave us the standard model on which we compare characteristics of the delegation of authority to divisions in Japanese firms with ones in Americans.
    4. Interview of Japanese Corporations : We interviewed four Japanese corporations on the topic of delegation to in-house and out-house divisions of business unit. This illuminates the comparative characteristics and limits in Japanese firms with ones in Americans.
    5. Plan of Future Research : We will have (1) to revise estimations of commitment model to resolve the problems in explanatory variables, (2) to develop more the study of management strategy of business group, which includes hiving off, from a viewpoint of comparative study, and (3) to do a new questionnaire research on the whole subsidiaries and affiliates of a few American corporations.

    まず理論研究については,当初の計画で想定していた「企業内部の昇進パターンと外部労働市場の競争性」とはやや焦点が異なるが、「人事部の集権化と分権化」をテーマとした研究論文を完成させた.(この対象の変化は、実証研究の対象である外資系企業の歴史分析から生じたものである.)日本企業は欧米企業と比べて人事部が集権化しているといわれるが,このような人事の集権・分権を理論的に厳密に分析した研究はない.本研究では,不完備契約アプローチに基づいて,人事が集権化している場合には「過剰」な介入が生じて,組織全体のパフォーマンスが低下すること,及び,人事を分権化することによって非効率な意思決定のコストが生じるという問題があるが,人事部の過剰介入の問題が緩和されるという利点が生まれることを証明した.そして最適な形態が集権か分権かを決定する要因を分析し,日本の他の雇用慣行とのシステム効果を考察した.
    実証研究については,すでに選定されていた外資系企業の人事担当者とのインタビューを行い,データの収集を継続中である.歴史的にこの企業が人事の集権化,分権化を何度か行なっていることが明らかになり,理論分析のための視点を提供してくれている.この集権化、分権化と雇用慣行との関係を詳しく探るために人事データの収集を開始したが、企業が新しい情報システムを構築中で、そのシステムがスタートしなければ必要なデータを得ることができず,研究は大幅な遅れを生じることになった。本年3月にようやくシステムがスタートしたため,実証研究はこれからの展開に期待することになった,

    We found the following points.
    (1) The most important element which determines the promotion in the Japanese firms is individual performance. The followings are luck, full, and schoolong.
    (2) Seniority system in Japan worked fairly well.
    (3) Corporate governance in Japan suggests that firms in Japan can be judged as labor managed firms because employers attempt to keep employees' employment.
    (4) "What university he graduated" is important to determine promotion.
    (5) It is desirable to determine promotion based on individual performance, and to treat engineers more favorably.
    (6) Professional workers should be treated equally as managerial workers.

    1 新会社支配理論を用いて、会社法の新たな一般理論を構成しようとする本研究の目的はほぼ達成された。すなわち、伝統的理論は、株主の所有を中心とした理論であるが、新理論は、株式会社において支配の制度(資本多数決制度)が内在的に貫徹していると把握し、株式会社制度を所有の制度と支配の制度とに峻別し、両者の相互関係を論理化することで、株式会社の機構、株主権などを再構成するものとなった。
    2 伝統的理論の側の新たな試み、すなわち、(1)イギリスにおける自主ルール、(2)市場メカニズムによる企業統制、(3)機関投資家と信託法理、(4)企業ファイナンスとコ-ポレート・ガバナンス、などに関して、新しい知見が示された。とくに、(3)の議論は、新会社支配理論をさらに展開させた。
    3 法と経済学派の会社法理論、および、経済学における企業理論について、理解を深めた。とくに、これまでの会社法学にはインセンティブ概念が欠落しており、また従来エイジェンシー・コストばかりが重視されてきたが、今後はコミットメント概念が重要なキーワードになるというきわめて重要な知見をえた。
    4 新会社支配理論は、このインセンティブおよびコミットメント概念と親和性を有しており、会社法学と経済学の連係を可能にすることが指摘された。
    5 今後、新一般理論を肉付けし具体的な会社法モデルを作成すれば、会社法学と企業経済学の両面から、国際的な理論交流は十分実現できる見通しがたった。その実現のために、全員研究の継続を切望している。
    6 会社法に焦点を当て、徹底的な学際研究を行った点に本研究の特色があるが、きわめて刺激的で啓発に富んだ研究企画となった。現段階での成果公表も、学術振興上少なからざる意義を有すると考える。

    The purpose of this research was to study various aspects of the Japanese firm, such as corporate governance, internal organization, inter-firm relationship, and firm-government relationship, as well as the systematic effects of those aspects, by organizing the 32nd and 33rd TCER Hakone conferences. Based on the research results from the 1993 conference(held at Odakyu Yama No Hotel in Hakone, March 28-30,1994), the program committee planed publishing the conference volume in Japanese. In order to make the relationships among the papers more explicit and secure, the authors held frequent meetings. The 33rd conference was held, as originally planned, in Hakone on March 27-29,1995. Eleven papers were presented, followed by extensive discussions by two discussants and the audience. The grant was utilized as meeting and travel expenses for the program committee and the conference.
    The conference volume entitled The Economic Analysis of the Japanese Firm as a System will be published from the University of Tokyo Press in September 1995. It is quite likely that the volume will become the standard reference of the analysis of Japanese firms via modern economic techniques.

    In this research, we attempted to construct new analytical frameworks to examine desirable social institutions as well as environments, such as organizational forms, social customs and global environments, in an economic system using game theory and dynamic economic system theory.
    1. We undertook a game theoretic research to examine decentralized resource allocation under different social institutions and environment so that we can design a desirable institutions and environments. In particular, we analyzed significance and effects of introducing lotteries in implementing social decision function in decentralized manner, tradeoffs between liberty and efficiency in restricting strategy sets of each individual within a society. We also showed, using evolutionary game theory approach with bounded rational players, the importance of the role of custom in inducting coordination among players, and, using experimental game theory, the role of social norms in human decision making.
    2. We analyzed how the extent of authority delegations, wage structure and promotion system within an organization affect the degree of cooperation and information exchange among employees, and characterized the Japanese organizational structure compared with those in other countries.
    3. We characterized the desirable properties of carbon tax, in view of dynamic efficiency as well as international equity, as a measure against global warming. We also analyzed the mechanism of how the business cycle diffuses dynamically and internationally using non-linear dynamics, and examined how asymmetric information affects macro-economic behavior through investment using monopolistic competition models.

  • 自己イメージ選好を持つメンバーからなるチームのインセンティブ：理論と応用

    2017  

    　View Summary

    各メンバーが他の複数のメンバーの「目」を気にするという自己イメージ選好を持つメンバーから成るチームにおけるインセンティブ問題を定式化し，理論的分析を行った．第1に，チームの規模 (人数) とインセンティブとの関係を考察し，チームの平均努力水準がチーム規模の増加関数となるための条件を明らかにした．第2に，自己イメージ選好についてメンバー間の異質性を導入し，誰の「目」を気にするかという問題を考察した．この分析結果を応用して，取締役会に過半数に満たない独立取締役を導入することや，外部から新しい社長を迎える (新しい「血」を組織に導入する) ことがプラスの効果を生み出す条件を明らかにした．
