Fairtrade consumers, by enacting their political and moral concerns through consumer choice, are at the same time constructing themselves as ethical selves. I will argue that they can only do so by drawing on cultural contexts. While fairtrade is instituted in supranational organizations and acts on a global level, there are still differences on a national level. On the basis of an Anglo‐German study, this paper seeks to map out the cultural contextualization of fairtrade consumption on both a supranational and a national level. The paper identifies the framing role of global consumer culture and an implicit ethics of equitability inscribed in capitalist practices of exchange and specifies how these play out differently in Germany and the UK. In both cases, there are strong references to sovereign consumer choice, and expectations of equitability in commodity exchange have been found. But while, in the British case, there is more emphasis on individual choice and taste, German fairtrade consumers seem to follow more what they perceive as an authoritative discourse. And, while British respondents envisaged the relation to be achieved with producers along the lines of a business relationship, German respondents conceptualized it more as a paternalistic employment relation between fairtrade organizations and producers. Differences will be explained in terms of distinctive consumer cultures, national moral economies and colonialist histories. I will argue that the two national settings not only offer different opportunities and challenges in terms of market success but also pose distinct ethical questions for fairtrade marketers. 相似文献

We consider a tournament between two workers of different abilities who choose both human capital investment and effort. The employer can influence the workers’ behavior by determining the sequence of human capital investments, i.e. the training design. The workers can either invest simultaneously or sequentially with the favorite being the first mover or sequentially with the underdog as first mover. The results show that the outcome of the tournament crucially depends on the employer’s choice of training design and on the ability difference between the workers. If the two workers clearly differ in their abilities the employer will prefer simultaneous human capital accumulation. However, if the abilities of the two workers are rather similar the employer optimally chooses sequential human capital accumulation with the underdog being the first mover. 相似文献

Like other broad disciplines in the media/communications field, communication science is characterized by rapid growth and increasing diversity and hence confusion. That also affects the discipline’s scholarly associations. So the German Association for Communication Science (Deutsche Gesellschaft für Publizistik- und Kommunikationswissenschaft, DGPuK), the largest German-speaking association in this field, conducted a survey among its members in early 2003. This article reports on the design and findings of this study, focusing on the perception and evaluation of the association and on the scholarly orientations (theoretic perspectives and methodologies) of its members. Various subgroups within the DGPuK diverge in their positions and opinions. This applies in particular to the less well represented research traditions and subdisciplines (as compared to the social-scientific mainstream), which tend to view the DGPuK as one-sided. Deviations also show for professionals working outside the academic field (as compared to DGPuK members from universities) and in part for older members and women. The findings not only give an up-to-date picture of the state of the DGPuK but also shed light on the situation and development of the discipline as a whole. 相似文献

Transferring knowledge to an agent makes him more successful or productive, which is beneficial for the principal. However, knowledge transfer also increases the agent’s outside option. I identify two reasons for withholding knowledge — to reduce labor costs within a principal–agent relationship, and to weaken the agent in case of a separation. Moreover, the role of synergy is discussed both for building up a principal–agent relationship and for transferring knowledge. While synergy is decisive for knowledge transfer, cooperation between the principal and agent may even take place in the absence of synergy. Furthermore, I analyze whether the principal is more likely to transfer knowledge to a more able or to a less able agent. Finally, the advantages and disadvantages of a noncompetition clause are briefly discussed. 相似文献

In this paper we present a statistical analysis of four foreign exchange spot rates against the U.S. Dollar with several million intra-day prices over 3 years. The analysis also includes gold prices and samples of daily foreign exchange prices over 15 years. The mean absolute changes of logarithmic prices are found to follow a scaling law against the time interval on which they are measured. This empirical law holds although the distributions of the price changes strongly differ for different interval sizes.Systematic variations of the volatility are found even during business hours by an intra-day analysis of price changes. Seasonal heteroskedasticity is observed with a period of one day as well as one week as the result of an analogous intra-week analysis; taking this into account is necessary for any future study of intra-day price change distributions and their generating process. The same type of analysis is also made for the bid-ask spreads. 相似文献

Considering oligopolistic contests with R&D spillovers and strategic delegation three results can be obtained: (1) There exist multiple asymmetric equilibria where one owner highly favors sales as a basis for his manager's incentives which drives the other firm out of the market. (2) If R&D spillovers are zero, a managerial firm will have a strong strategic advantage when competing with an entrepreneurial firm. If both owners endogenously decide about delegation, each owner's dominant strategy will be to delegate, given that the manager's reservation value is not too large. (3) If R&D spillovers are maximal, collusive market outcomes become very likely, which makes strategic delegation less important. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献
