Manufacturers often face a choice of whether to recover the value in their end‐of‐life products through remanufacturing. In many cases, firms choose not to remanufacture, as they are (rightly) concerned that the remanufactured product will cannibalize sales of the higher‐margin new product. However, such a strategy may backfire for manufacturers operating in industries where their end‐of‐life products (cell phones, tires, computers, automotive parts, etc.) are attractive to third‐party remanufacturers, who may seriously cannibalize sales of the original manufacturer. In this paper, we develop models to support a manufacturer's recovery strategy in the face of a competitive threat on the remanufactured product market. We first analyze the competition between new and remanufactured products produced by a monopolist manufacturer and identify conditions under which the firm would choose not to remanufacture its products. We then characterize the potential profit loss due to external remanufacturing competition and analyze two entry‐deterrent strategies: remanufacturing and preemptive collection. We find that a firm may choose to remanufacture or preemptively collect its used products to deter entry, even when the firm would not have chosen to do so under a pure monopoly environment. Finally, we discuss conditions under which each strategy is more beneficial. 相似文献

由竞争对手组建的竞争性战略联盟,正逐渐成为联盟理论研究的焦点。本文以同一区域内、不对称的竞争性双寡头为研究对象,针对新产品研发和销售两阶段,对比分析了不合作与结成竞争性联盟共同研发并在新市场中联合销售新产品这两种模式下的均衡研发投入和均衡利润,得出了竞争性双寡头组建联盟的共赢区间。研究结论有助于我国企业借助竞争合作关系进入国际市场,提高国际竞争力。 相似文献

Zusammenfassung Rechtsansprüche gegen Fluggesellschaften und Flugzeughersteller in Folge einer Flugzeugkatastrophe richten sich nach einer
Flut rechtlicher Bestimmungen, die aus internationalen Abkommen, Vereinbarungen zwischen Fluglinien sowie aus Bundes- und
Landesrecht resultieren. Die jeweilige Rechtsgrundlage in einem spezifischen Fall h?ngt von verschiedenen Umst?nden ab, die
mit einem Unfall verbunden sind. Es überrascht daher nicht, dass zugesprochene Schadensersatz- und Schmerzensgeldzahlungen
an die Angeh?rigen der Opfer von Fall zu Fall erheblich divergieren. In unserer Studie mit U.S.-amerikanischen Daten untersuchen
wir, inwieweit der kurz- und langfristige Erfolg von Fluggesellschaften und Flugzeugherstellern durch Flugzeugkatastrophen
beeinflusst wird und wir eruieren diejenigen Determinanten, die Performanceunterschiede erkl?ren k?nnen. Verwandte Untersuchungen
haben sich weitgehend auf Effekte für Markennamen oder steigende Versicherungspr?mien als Ursachen für Aktienkursverluste
konzentriert. Unsere Ergebnisse zeigen darüber hinaus, dass das regulatorische Umfeld einer spezifischen Unglückssituation
erheblichen Einfluss darauf hat, wie Finanzm?rkte reagieren. Die Reaktionen der Marktteilnehmer weisen darauf hin, dass die
unterschiedlichen Berechnungsgrundlagen für die Opferentsch?digung recht klar erkannt werden.
The role of aviation laws and legal liability in airplane accidents: A financial market perspective
Summary Legal liability claims against airlines and airplane manufacturers following an aviation disaster are determined through a myriad of international treaties, intercarrier agreements, and federal and state laws. Which law applies in a specific situation depends on various circumstances surrounding the accident. As a result, pecuniary and non-pecuniary damage awards for the families of the accident victims may vary substantially from case to case. Using U.S. data, our study examines how aviation disasters affect the short and long-term performance of airlines and airplane manufacturers and explores the factors that drive the performance differences. While prior research has largely focused on brand name effects and rising insurance premiums as possible determinants of stock price losses, our results suggest that the regulatory environment that applies to a given aviation accident has a significant impact on how the market reacts to its announcement. Inequities in the valuation of a human life are clearly reflected in stock price reactions. While recent regime changes have helped eliminate some of these imbalances further reform may be necessary.

Corporate Management,Industry Competition and the Sustainability of Firm Abnormal Profitability 总被引:2,自引:0,他引:2
This paper models the sustainability of firmabnormal profitability and uses theeffectiveness of corporate managementcapabilities as a test to examine its impact onthe sustainability of firm abnormalprofitability. The role of industry competitionas a moderator between the effectiveness ofcorporate management capabilities and thesustainability of firm abnormal profitabilityis also examined. Consistent with theresource-based view of the firm, we found thatthe effectiveness of corporate managementcapabilities positively influence thesustainability of firm abnormal profitability.This implies that corporate managementcapabilities are important contributors to theentire bundle of firm-specific resources andcapabilities which enable some firms togenerate competitive advantages that aresustainable. The effectiveness of corporatemanagement capabilities has a larger influenceon the sustainability of firm abnormalprofitability for firms in lowly competitive ormonopolistic industries than firms in highlycompetitive industries. The findings supportthe notion that not only do firm capabilitiesyield sustainable competitive advantages andabnormal profitability, but also industrycompetition reinforces the impact of firmcapabilities in yielding sustainable abnormalprofitability. 相似文献

Takeover and acquisition of corporations is awell-researched area and has been becomingincreasingly important. Much less research emphasishas been devoted to takeover activity within thegeneral area of financial services with thisparticularly the case for the building society sector.The building societies being mutual companies havespecial characteristics. The building societies andother financial mutuals like the corporations doencounter an acute agency problem. This opens up apotential application of Grossman and Hart theory oftakeovers bids as the individuals have option to freeride, securing knowledge that the regulatory processrenders their deposits de facto risk-free investment.This free-rider problem, like the corporations can beovercome by inducing hostile takeover.Some empirical studies of mergers activities withinthe building society sector have dealt with onlyintra-sectoral mergers. However, they have not lookedat inter-sectoral mergers and have not addressedefficiency issues in a general equilibrium frameworkusing game theory.In this paper I suggest a mechanism for merger at parwith sales of stocks of a corporation to organisebuilding societies' takeovers. I develop a two-stagegame between the members of building societies and theraider. Analysis of non-cooperative voting behaviourof members of Cheltenham and Gloucester buildingsociety shows that the actions of the members of thebuilding society may also give rise to less thanoptimal results as they may not be acting in their bestinterests. The members of the building society cangain if a hostile takeover is induced rather than afriendly takeover. The paper also examines the freerider problem and ex-ante efficiency in a generalequilibrium framework. 相似文献
