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 Using rare historical documents from Po rtugal and Africa, this study traces the effects of Portuguese expansion on the economies of East Africa and trade in the Indian Ocean.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.

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

Entrepreneurs and the Process of Obtaining Resources   总被引:1,自引:2,他引:1  
This paper examines the process of how entrepreneurs assemble resources. In the model, the entrepreneur's challenge is to convince two complementary resource providers to commit their resources to a new venture. Before committing their resources, one of them needs to perform a costly evaluation. The entrepreneur has a problem with getting sufficient attention, because each provider has an incentive to wait and free-ride on the other's evaluation. For some parameters the entrepreneur solicits both partners with equal intensity ("knocking on every door"); for others, the entrepreneur always solicits the same partner ("pestering"). For many but not all parameter ranges, the process of assembling resources takes too much time relative to what is socially efficient. The model thus explores what factors facilitate or hinder the creation of new firms.  相似文献

Based on economic methodology we model an ecosystem with two species in predator–prey relationship: mice feed on grain and grain feeds on a resource. With optimizing behavior of individual organisms a short-run ecosystem equilibrium is defined and characterized that depends on the farmer's use of fertilizer and pesticide and on the mice population which, in turn, is affected by pesticides. In that way, a microfounded agricultural production function is derived. Linking a sequence of short-run ecosystem equilibria yields the growth function of the mice population which is thus derived rather than assumed. In each period the farmer harvests all grain in excess of some given amount of seed. If she maximizes her present-value profits, optimal farming is characterized by either using no pesticide or a moderate amount of pesticide or by applying a chattering control. Pest eradication is never optimal. On the other hand, if the farmer takes into account steady-state mice populations only, it may be optimal to eradicate mice or to use no or a moderate amount of pesticide depending on prices as well as on the shape of the grain production function which is determined by microparameters of grain reproduction.  相似文献
