I analyze a well-known and moving passage from John Steinbeck's novelThe Grapes of Wrath. This passage provides an excellent illustration of one of the central questions about corporate moral agency: Is corporate moral agency anything over and above the agency of individual human beings? The passage in question is a debate about whether or not the actions of a particular company are anything over and above the actions of individual human beings.  相似文献

Prior to the sixteenth century, the Indian Ocean trading network was one of the wealthiest commercial regions in the world. It included states of East Africa, the Arabian peninsula, the Indian subcontinent, Southeast Asia, China and Japan. By circumnavigating Africa, Portugal was the first European nation to gain access to the region. Through the exercise of naval superiority, blockading of strategic shipping lanes, imposition of duties and expulsion of Swahili and Muslim merchants, Portugal exercised a mercantile monopoly which ultimately led to the region’s rapid economic decline. Using rare historical documents from Po rtugal and Africa, this study traces the effects of Portuguese expansion on the economies of East Africa and trade in the Indian Ocean.  相似文献

We test the robustness of the APT to two alternative estimation procedures: the Fama and MacBeth (1973) two-step methodology; and the one-step procedure due to Burmeister and McElroy (1988). We find that the APT is indeed sensitive to the chosen estimator and assumptions about the factor structure of stock returns. We believe that our findings have implications for the estimation of asset pricing models in general.  相似文献

Seit einigen Jahren stellt der Europäische Gerichtshof vermehrt Regelungen der nationalen Steuersysteme in Hinblick darauf in Frage, ob sie mit dem EG-Recht konform gehen. Im aktuellen Fall Marks & Spencer entscheidet der Gerichtshof, ob Konzerne Verluste ausländischer Töchter mit inländischen Gewinnen verrechnen dürfen. Welche Wirkung hätte eine EU-weite Verlustverrechnung auf das deutsche Steueraufkommen?Prof. Dr. Clemens Fuest, 36, ist Direktor des Finanzwissenschaftlichen Forschungsinstituts an der Universität zu Köln und Mitglied des Wissenschaftlichen Beirats beim Bundesministerium der Finanzen; Thomas Hemmelgarn, 30, Dipl.-Volkswirt, ist Mitarbeiter an demselben Institut; Fred Ramb, 39, Dipl.-Volkswirt, ist Mitarbeiter der Deutschen Bundesbank, Economic Research Centre, in Frankfurt. Dieser Artikel repräsentiert die persönliche Auffassung der Autoren und entspricht nicht notwendigerweise der Position der Deutschen Bundesbank oder ihrer Mitarbeiter.  相似文献

Previous studies on strategic groups have mainly focused on their static characteristics in order to test the theory of strategic groups and intraindustry performance differences (Porter, 1979; Cool and Schendel, 1988; Fiegenbaum and Thomas, 1990). In contrast, this study takes a longitudinal, dynamic perspective and describes the forces driving strategic group membership and structural evolution. It proposes that a strategic group acts as a reference point for group members in formulating competitive strategy. A partial adjustment model of strategic mobility is then developed which incorporates the idea of a strategic group as a reference group. It models strategic change in an industry both within and across strategic groups. The model is tested in the context of an in-depth industry analysis of the more significant firms in the insurance industry over the 1970-84 time period. The results suggest that strategic groups act as reference points for firm strategies and that predictions of future firm strategies and industry/group structures may also be successfully derived.  相似文献

This study of production operations in 95 New Jersey manufacturing firms explains the widely replicated curvilinear relationship between first line supervisory span of control and Woodward's technological complexity scale. Revisiting Woodward led to the initial proposition that the relationship was a by-product of the differing degree of task variability among the major types of production operations. A subsequent literature review of administrative requirements suggested the importance of size, complexity and automaticity on supervisory span of control. Our data indicate that variations in the span of control of production operations classified according to Woodward's scale are attributable to the underlying effects of size and task complexity. Technology, whether operationalized as Woodward's production types or automaticity of machinery explained little variation in the span of control of first line supervisors.  相似文献

We examine the statistical performance of inequality indices in the presence of extreme values in the data and show that these indices are very sensitive to the properties of the income distribution. Estimation and inference can be dramatically affected, especially when the tail of the income distribution is heavy, even when standard bootstrap methods are employed. However, use of appropriate semiparametric methods for modelling the upper tail can greatly improve the performance of even those inequality indices that are normally considered particularly sensitive to extreme values.  相似文献
