  • Exclusive Contracts with Complementary Inputs Reviewed

    Hiroshi Kitamura, Noriaki Matsushima, Misato Sato

    International Journal of Industrial Organization   56   145 - 167   2018.1

    　More details

    Language：English   Publishing type：Research paper (scientific journal)   Publisher：Elsevier Inc.  

    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 benefits not only the downstream firm, but also the complementary input suppliers, by raising complementary input prices. Thus, the downstream firm is unable to earn higher profits, even when socially efficient entry is allowed. Hence, the inefficient incumbent supplier can deter socially efficient entry by using exclusive contracts, even in the absence of scale economies, downstream competition, and relationship-specific investment.

    Incorporating Nash bargaining into the standard one-buyer-one-supplier framework in the Chicago School critique, we show a possibility that an inefficient incumbent supplier can deter a socially efficient new supplier entry through exclusive contracts.

  • Relationship-Specific Investment as a Barrier to Entry Reviewed

    　More details

    Language：English   Publishing type：Research paper (scientific journal)   Publisher：SPRINGER WIEN  

    This study constructs a model of a relationship-specific investment in a dynamic framework. Although such investment decreases operating costs and increases the current joint profits of firms in vertical relationships, its specificity reduces the ex-post flexibility to change a trading partner in the future. We demonstrate that whether the investment contract deters entry even in the absence of exclusionary terms depends on not only the specificity but also the efficiency of the investment. We also show that an increase in the investment efficiency does not necessarily improve the equilibrium social welfare.

  • Exclusive Contracts when the Incumbent can Establish a Direct Retailer Reviewed

    　More details

    Language：English   Publishing type：Research paper (scientific journal)   Publisher：SPRINGER WIEN  

    This paper constructs a model of anticompetitive exclusive dealings with potential downstream competition. Unlike in previous studies, the incumbent can establish a direct retailer with some fixed payment and can offer an exclusive contract to a downstream buyer twice. We show that the existence of these two options helps the incumbent deter socially efficient entry and earn almost monopoly profits even in the absence of scale economies and downstream competition.

  • Free Entry, Market Diffusion, and Social Inefficiency with Endogenously Growing Demand Reviewed

    Hiroshi Kitamura, Akira Miyaoka, Misato Sato

    Journal of the Japanese and International Economies   29   98 - 116   2013.9

    Language：English   Publishing type：Research paper (scientific journal)  

    This paper analyzes market diffusion in the presence of oligopolistic interaction among firms. Market demand is positively related to past market size because of consumer learning, networks, and bandwagon effects. Firms enter the market freely in each period with fixed costs and compete in quantities. We demonstrate that the nature of the inefficiency under free entry can change as the market grows, and more importantly, that S-shaped diffusion can be a signal that the number of firms under free entry is initially insufficient, but eventually excessive. © 2013 Elsevier Inc.

    メーカーと小売店などの垂直的取引において，競合他社との取引を禁ずる契約を排他条件付取引契約という．こうした契約は，ライバル企業を排除する反競争的な効果を持つ．これまでの研究により，特定の状況において，排他契約によるライバルの排除が発生することが明らかになっている．現実の競争政策への対応を考えると，更なる状況の整理が求められる．本研究では，排他条件付取引関連の個別の事件の特性を考慮し，理論分析及び実験分析を行う．
    2019年度の理論研究と実験研究の進捗状況は以下のとおりである．まず，理論研究において，前年度に基本モデルの結果の確認ができた耐久財市場における排他条件付取引契約の拡張分析を行った．分析の結果，基本モデルとは異なる消費者効用での設定においても，反競争的な排他条件付取引契約が締結されることが明らかになり，結果の頑健性が確認できた．さらに，得られた研究成果を日本応用経済学会，日本経済学会，欧州産業経済学会（EARIE）などの国内外の研究会で報告した．現在，研究報告で得た助言をもとに，英文査読誌への投稿に向けて論文の改訂作業を進めている．
    次に，実験研究では，前年度に引き続き， Kitamura, Matsushima, and Sato (2018)の実験分析を進めた．2019年度では，2018年度に実施した基本実験の設定から，差別化の程度や交渉力を変化させ，排他条件付取引の実現可能性がどの程度変わるかを検証する実験を行なっていたが，新型コロナウイルスの流行により，年度内に予定していたすべての実験を終了することができなかった．また，これ以外にも排他条件付取引に関する経済実験を実施する予定であったが，上記の理由により，実施ができなかった．

    This research explores two things focusing on domestic firms’ vertical or horizontal organization change: what kind of strategic actions domestic firms take when facing efficient firm’s entry and what kind of impacts can be considered in a market when efficient firms actually enter. We show the circumstances where a domestic firm can deter multinational entry by closing an exclusive contract, the impact of multinational M&A with domestic supplier of intermediate input on domestic vertical organization form, the situation where multinational entry enables domestic firms to horizontally integrate from a competitive policy perspective, and its impacts.
