Close relationships between and among supply chain members are becoming more prevalent. However, there is lack of agreement in the literature and in practice concerning the characteristics of different interorganizational relationships. The resultant confusion is an obstacle to the progression of research and could cause problems among firms in a supply chain. Based on previous research and an exploratory study conducted with company executives responsible for supply chain management activities, this article seeks to introduce the concept of relationship magnitude (i.e., the extent or degree of closeness or strength of the relationship) and differentiate it from relationship type (i.e., classes of relationships that share common traits). Implications for managers and opportunities for future research are provided. 相似文献

Zusammenfassung Koordinierte Strategien für wirtschaftliche Zusammenarbeit zwischen Europa und den Vereinigten Staaten. - In diesem Aufsatz
wird die dynamische Spieltheorie auf die Koordinierung der Politik zwischen den Vereinigten Staaten und der EWG in einem stark
aggregierten Modell angewandt und folgendes gezeigt: (i) Eine Politik, die den Einflu\ von Ma\nahmen anderer L?nder vernachl?ssigt,
führt in den USA zu Fiskalischen Einschr?nkungen und einer Verminderung der staatlichen Interventionen, in Europa dagegen
zu einer Nachfragestimulierung, verbunden mit einer kontinuierlichen Herabsetzung des Diskontsatzes. Die EWG-L?nder sind,
da sie ihre Politik nicht koordinieren, nach einigen Jahren wegen Zahlungsbilanzschwierigkeiten zu einer kontraktiven Nachfragepolitik
gezwungen. (ii) Koordinierte Strategien best?tigen, da\ nicht-synchronisierte Politiken die Weltwirtschaft stabilisieren k?nnen.
(in) Kooperation verbessert die wirtschaftlichen Leistungen, ausgedrückt in den Wachstumsraten und den Zahlungsbilanzen. Allerdings
erbringt die ausdrückliche Zusammenarbeit kaum noch zus?tzliche Vorteile zu denen, die bereits im Rahmen der vollen Koordinierung
erreicht werden k?nnen.
Resumen Estrategias coordinadas de cooperación económica entre Europa y los EEUU.- La aplicación de un modelo dinámico de teoría de juegos a la coordinatión de política económica entre los EEUU y la CEE, como parte de un modelo altamente agregado de la economía mundial, permite concluír en este trabajo que (i) políticas que ignoran la influencia de medidas tomadas en otros países dan lugar a una contractión fiscal y a una menor interventión del Gobierno en los EEUU, pero a una estimulación de la demanda combinada con reducciones continuas de la tasa de descuento en Europa; al seguir políticas descoordinadas los países de la CEE están obligados a contraer la demanda agregada al cabo de unos a?os, debido a los problemas de balance de pagos, (ii) estrategias coordinadas confirman que políticas no sincronizadas pueden estabilizar la economía mundial; (iii) la cooperación favorece a la economía en términos de tasas de crecimiento y balance de pagos. Sin embargo, los beneficios adicionales de una cooperatión explícita resultan marginales en comparación con los beneficios ya alcanzados por la solución con coordinación total.
Résumé Stratégies coordonnées pour la coopération entre l’Europe et les E.U. - En appliquant la théorie dynamique de jeu à la coordination de politique entre les E.U. et la CEE dans un modèle fortement agrégé de l’économie mondiale, cet article arrive aux conclusions suivants: (i) La politique qui ignore l’influence des actions suivies dans d’autres économies mène à la réduction fiscale et à moins interventions gouvernementales dans les E.U., mais à une stimulation de la demande avec des réductions continuelles du taux d’escompte en Europe. En cas d’une politique pas coordonnée les pays CEE sont forcés à prendre des mesures pour freiner la demande agrégée après quelques années à cause des problèmes de la balance des paiements. (ii) La stratégie coordonnée confirme que des politiques pas synchronisées pourraient stabiliser l’économie mondiale. (iii) La coopération peut élever le taux de croissance et améliorer la balance des paiements. Cependant, les gains additionnels d’une coopération explicite sont petits en comparaison avec les bénéfices déjà gagnés à l’aide d’une solution complètement coordonne’e.相似文献

The strategic marketing decision regarding the selection of a brand name has long been an area neglected by academic researchers. This study attempts to apply psychological theory to this important strategic decision area. Specifically, the applicability of a dual-coding theory of memory to brand name recall/recognition is tested in an experimental setting. Results indicate, on average, a significant one hour and two day recall/recognition advantage of high imagery over low imagery brand names across a variety of product categories. 相似文献

The purpose of this paper is to examine changes in stock return variances following option introduction. The sample consists of National Market System stocks and employs both transaction returns and returns based on bid and ask quotes. Variances are decomposed into portions attributable to bid-ask spreads, return autocorrelations, and intrinsic variances. Spreads play a negligible role in explaining variance changes. A generally positive component to short-term autocorrelations falls following option introduction, increasing variances over short holding periods. Intrinsic variances fall prior to the October 1987 crash, but do not change after the crash with option introduction. 相似文献

Indian industry is under pricing pressure after the government cut tariffs in a phased manner as per the WTO agreements. In order to be competitive, the consensus opinion in government, academics and industry is the implementation of a VAT in India. The paper evaluates the welfare implications of a VAT in the static and a sequentially dynamic context after accounting for the political and administrative constraints facing the Indian government in implementing a VAT. Replacing the old indirect tax structure with a VAT is welfare worsening. The increase in final consumer prices on account of reduced tax base leads to higher price of essentials, causing welfare loss. Zero rating v/s exemption plays an important role on welfare, with lower welfare loss if essential commodities are exempt from VAT. Agriculture sector unambiguously plays a crucial role in welfare. 相似文献

在我生命中各个阶段里,我与学术界不知不觉地频频有缘。启蒙时期,我科到名师的熏导业已浸淫于国学;经史子籍,无所不读,撰文作诗,直追唐宋,俨然是一个“小老学究”。当我入仕时,一秉传统士大夫的志趋,一心为国为民,在我自我流放期间,发现我唯一可谋生的本领是学术,我既没有继承万贯家财,也没有在当权时放出许多人情,作为经商的捷径,实际上,我曾试探经商之路,但是在没有有力的后台引见下,我意识到,要加入一家企业,条件是能够为其带来多少商机,我对这种用才标准并不欣赏,在此情形下,要做一个小企业家,其生活方式也难以适应,特别是对我的妻女是一种冒险。 相似文献

We investigate bank stocks'sensitivity to changes in interest rates and the factors affecting this sensitivity. We focus on whether the exposure of commercial banks to interest rate risk is conditioned on certain balance sheet and income statement ratios. We find a significantly negative relation between bank stock returns and changes in interest rates over the period 1991–1996. We also find that bank characteristics measured from basic financial statement information explain bank stocks'sensitivity to interest rate changes. These results suggest that bank managers, analysts, and regulators can use this information to assess the relative risk exposure of banks. 相似文献

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention. 相似文献

The personal computer (PC) marketplace in the US presents a dizzying array of component suppliers and products. No single firm dominates the industry with a complete package of hardware and software components. Although one company's operating systems and general-purpose applications are installed on most PCs in the US, the other system components—processors, memory, storage devices, display adapters, monitors, specialized applications, and so on—come from any number of sources. David T. Methe, Ryoko Toyama, and Junichiro Miyabe point out that the PC industry in Japan also exhibits this decentralized nature. However, they also note that despite the decentralized network structure of the Japanese PC industry, one company—NEC—was able to achieve a dominant market share. To provide insight into the key issues involved in the management of complex technology, they contrast NEC's strategic approach to product development and organizational learning with the approaches taken by Fujitsu—the firm that placed a distant second in this market. Despite matching NEC in terms of technological capabilities, financial resources, and managerial talent, Fujitsu never managed to threaten NEC's dominance of the PC market in Japan. Fujitsu continually emphasized technological leadership, even at the expense of protecting its installed base. Poor coordination of resources and product development efforts resulted in incompatibilities among Fujitsu's various products, and the company failed to foster close relationships with suppliers of such key technologies as software and peripherals. NEC's PCs did not enjoy the advantages of first-to-market status or technological leadership. Instead, NEC achieved market dominance by finding the combination of product technologies that met the needs of the greatest number of consumers. Throughout almost 20 years of competition in the PC industry, NEC successfully maintained consistency and backward compatibility across its product lines. NEC also recognized the importance of third-party software developers, and carefully cultivated relations with these firms as a source of competitive advantage. In other words, NEC struck the right balance between three key factors: technological innovation, motivation of third-party developers of software and peripherals, and service to its installed base of customers. 相似文献

This paper employed eleven data series which consist of stocks, bonds, bills, equity premiums, term premiums, and various default premiums to investigate whether January seasonality reported in existing literature is robust across different states of the economy as this has important trading implications. For the periods 1926–1990, small stocks, small stock premiums, low grade bonds, and default premiums (spread between high grade, low grade and government bonds) reveal January seasonality and that the seasonality is robust across different states of the economy except for low grade bond returns and default premiums. January seasonality for low grade bond returns and low grade bond default premiums are primarily driven by results found during periods of economic expansion. Overall, January seasonality is more evident during the economic expansion periods although the magnitude of default premiums is larger during periods of economic contraction. Furthermore, prior findings of strong summer equity returns are primarily driven by the results found during the periods of economic contraction. It is also found that equity returns are generally higher during periods of economic expansion. 相似文献
