This article analyzes the adoption of B2B-e-business technology in German automotive supplier companies during the internet hype period, i.e. in the very early stage of technology diffusion. While from the outset e-business was assumed to be used by companies in order to increase efficiency and reduce costs, some previous IOS research and theoretical considerations suggest that both efficiency and environmental expectations can be important reasons for companies to implement e-business. On this backdrop, the paper analyzes the reasons for e-business technology adoption, focusing on the explanatory value of institutional factors like mimesis, coercion, and normative pressures. Theoretically based hypotheses are developed and tested using regression models with a quantitative data set of more than 1900 companies.The article tries to make an innovative contribution to the field of IOS research, first, by drawing on theories of organizational structuring — new institutionalism, social psychology, and transaction cost economics; second, variation of adoption rationales in different types of companies and different business functions inside a company is taken into account.It appears that the adoption of e-business is explained by external pressures from other customers, bandwagon effects and herding behavior during the e-business hype, and expectations and interests of professionals inside a company. In the ‘core’ areas of a firm, efficiency rationales play an important role, too. The data reveals that the reasons of e-business usage differ significantly by department and company type.  相似文献

Marine and permafrost-based methane hydrates are the largest existing fossil carbon resource. Their broad geographic distribution, especially in comparison to oil and conventional gas, make them a promising future source of energy. However, there is a danger of forcing the greenhouse effect in the event of a release of methane into the atmosphere as well as causing the collapse of oceanic slope sediments. Also the technical difficulties in extracting methane from hydrates are not yet fully resolved. Nevertheless, research on methane hydrates has been forced both on political as well as economic considerations in recent years and methane hydrates have several practical advantages, which make them a transitional solution worth looking at on the way to a future renewable-based energy supply. However, the knowledge of the potentials and risks of methane hydrates is still very poor, especially in the German-speaking public, administration and policies. This deficiency hopefully will be eased by this overview dealing with the current state of research and an outlook based on the most important findings.  相似文献

This paper analyzes timing issues on the German balancing power market. We focus the analysis on the length of the bidding period, i.e. the length of the time period a supplier has to provide balancing power capacities, and the question of how far before the beginning of a bidding period the auction should be carried out. We show that different load levels require different plants for the optimal provision of balancing power. In a longer bidding period, the power plants that have the lowest average cost in the bidding period are unlikely to be efficient in all hours of the bidding period. Hence, shortening bidding periods can increase efficiency. Furthermore, we show that an early commitment on a power plant’s mode of operation (when uncertainty about resulting spot prices is still relatively high) also reduces efficiency. This suggests that the auction should be held relatively close to the beginning of the bidding period. Furthermore, we discuss some advantages of a liquid real time market.  相似文献

Abstract

The idea of “Smithian growth” rests on a “natural” development out of agriculture through capital accumulation, and the division of labour. We confront these concepts with an “historical experiment” and the case of Danish agriculture in the nineteenth century. Specifically, we look at how accounting was used to promote specialization, ultimately in butter production, leading to the massive increases in productivity that Smith predicted. We also observe the emergence of Smithian “philosophers”. This ultimately led to the capital-intensive industrialization of Danish agriculture through butter factories, and general development. We argue that this establishes the historical relevance of Smith’s theories.  相似文献

Mit dem Bilanzrechtsmodernisierungsgesetz wollte der Gesetzgeber unter anderem eine im Verh?ltnis zu den IFRS gleichwertige, d. h. ebenso entscheidungsnützliche, aber einfachere und kostengünstigere Alternative bieten. Um dieses Ziel zu erreichen, wurden verschiedene Wahlrechte gestrichen, Bilanzierungsverbote aufgehoben und Bilanzierungsmethoden ver?ndert. Aus Sicht der Abschlusspolitik wurden damit einerseits explizite Wahlrechte verringert und andererseits implizite Wahlrechte geschaffen. Zudem bergen auch die übergangsvorschriften abschlusspolitisches Potenzial. Nach einer Einordnung der Abschlusspolitik und der Herausarbeitung der konkreten Potenziale werden die Konsequenzen in Bezug auf die Entscheidungsnützlichkeit diskutiert und die m?glichen Auswirkungen der ge?nderten Rechnungslegungsnormen am Beispiel der Bilanzierung von Pensionsverpflichtungen deutscher IFRS-Anwender empirisch belegt.  相似文献

This paper provides a closer look into the concept of eco-regions in Austria. The idea behind the eco-region is to merge organic farming and rural development into a territorial strategy. The actors proposing this are farmers as well as various stakeholders in regional development. A survey of current manifestations of eco-regions in Austria provides an overview and a base for a preliminary classification. It also indicates the eco-region concept as a potential answer to individual problem situations. The ‘Eco-region National Park Hohe Tauern’ serves as a specific case to assess the impact of this concept using the sustainable rural livelihood (SRL) framework. The case study proves that the concept of eco-regions delivers a range of improvements in the livelihood of small organic farms in less favoured regions. Moreover it supports the forging of new alliances, which can extend the principles of sustainability inherent to organic farming to other actors and sectors in the region. Thus it provides the framework for a territorial application of the principles of organic farming. But the case study also reveals potential dangers, especially from powerful market partners who use the concept for their purposes, dominating further development and creating new dependencies. Finally some general conclusions on the preconditions necessary to establish eco-regions are presented.  相似文献

This study evaluates 10-year US government bond yield forecasts and three-month US Treasury bill rate forecasts for the period between October 1989 and December 2004. In total, 136 forecast time series with approximately 13,800 forecast data were scrutinized, making this the most extensive analysis of interest rate forecasts to date. Not one of the forecast time series proved to be unbiased. In the majority of cases, information from the past was not efficiently integrated into the forecasts. The sign accuracy is significantly better than random walk forecasts in only a very few of the forecast time series. The modified Diebold–Mariano test for forecast encompassing reveals that the information content of most of the forecast time series is lower than that of the naïve forecasts, the simple ARIMA models, the implicit forward rates, or average interest rate expectations. The forecasting process is dominated by the present and past market situation.  相似文献

The issue of meat consumption has been a subject of interest that has been looked at from environmental, animal and human perspectives. This paper contributes to the discussion by clarifying the diversity of views with regard to the future of meat consumption. Two round Delphi expert interviews and a consumer survey were conducted in order to collect information. Five coherent future images were constructed: Traditional Approach, Business as Usual, Humans First, Wellness and Vegetarian Society. The discussion part of the paper presents possible ways of influencing meat consumption according to the holders of these different images of the future.  相似文献

Antitrust scholars have argued that exclusive contracts have anticompetitive, or at best neutral effects, if no efficiencies are generated. In contrast, this paper shows that exclusive contracts can have procompetitive effects, provided buyers are imperfect downstream competitors and contract breach is feasible. In that case, an efficient entrant is not necessarily foreclosed through exclusive contracts but induces buyers to breach. Because breaching buyers have to pay expectation damages to the incumbent, the downstream profits they obtain when breaching must be large enough. Therefore, the entrant needs to set a lower wholesale price than absent exclusive contracts, leading to lower final consumer prices and higher welfare.  相似文献
