In the EURURALIS project, a chain of models was used to predict the changes in sustainable development indicators for European human well-being, ecology and economy issues, for four alternative scenarios of the future socio-economic development. This paper describes the biodiversity analysis of the project. Models based on general relationships between environmental factors and biodiversity loss were combined with socio-economic, land-use and environmental models to derive data that were integrated into an interactive tool for policy makers. The biodiversity analysis takes into account the effects of land-use change, climate change, fragmentation by major roads, area of unfragmented patches, nitrogen deposition, forestry and disturbance. Results show that biodiversity is projected to decrease between now and 2030 in most countries for all scenarios, indicating that it is unlikely that the EU will be able to fulfill its commitment to stop biodiversity loss by 2010. This is mainly due to urbanization and increase in stress factors, and outweighs the area increase of nature arising from land abandonment. Merits, limitations and uncertainties of this approach to biodiversity assessment are discussed.  相似文献

Arrow's celebrated theorem of social choice shows that the aggregation of individual preferences into a social ordering cannot make the ranking of any pair of alternatives depend only on individual preferences over that pair, unless the fundamental weak Pareto and non-dictatorship principles are violated. In the standard model of division of commodities, we investigate how much information about indifference surfaces is needed to construct social ordering functions satisfying the weak Pareto principle and anonymity. We show that local information such as marginal rates of substitution or the shapes “within the Edgeworth box” is not enough, and knowledge of substantially non-local information is necessary.  相似文献

Managers increasingly seek to develop brand loyalty through sponsorship activities, though this relationship has not been solidly established. This article models and demonstrates the impact of sponsorship on brand loyalty. The studied concepts and relationships emerge from both the sponsorship and consumer-brand relationship literature. The experimental design relies on before and after measurements and multiple exposures to the sponsorship. Thus this study demonstrates that sponsorship exposure has a positive impact on brand affect, brand trust, and brand loyalty. The change in brand loyalty from before to after sponsorship exposure reflects two persuasion processes. First, self-congruity with an event enhances brand loyalty through event and brand affect. Second, perceived fit between the event and the brand has a positive effect on brand affect, through attitude toward the sponsorship, and on brand trust, such that it ultimately influences brand loyalty. Brand affect is identified as an important mediator of sponsorship effects.  相似文献

Firms increasingly rely on suppliers to perform tasks in new product development (NPD). Research has only recently begun to focus on the processes to manage this supplier development responsibility, and has hardly investigated how firms collect and analyze information regarding the cost and performance of alternative supplier offerings. Our study addresses this gap, through a field survey among 144 paired samples of project leaders and cost analysts involved in the same NPD projects. On the basis of literature and qualitative research, we conceptualize a substantive model. We first use a substantive validity assessment to vet the measures for the proposed constructs. We then test the substantive model with structural equation modeling using a multiple‐sample analysis. The results strongly show that monetary quantification of differences and detail gathering play significant roles in successfully leveraging supplier development responsibility. The findings support the hypothesis that the extent of development responsibility that suppliers have leads the development team to a more focused monetary quantification of the differences in alternative supplier offerings. Monetary quantification of differences has a significant, positive effect on the extent of supporting‐detail gathering and on the development speed of the project, whereas supporting‐detail gathering has a significant, positive effect on the product advantage of the new product as well as development speed. These findings are robust across the two functional perspectives. Our study complements the literature on interfirm control and monitoring by demonstrating the effects of selective and focused output controls.  相似文献

Regulating Banks through Market Discipline: A Survey of the Issues   总被引:2,自引:0,他引:2  
Abstract.  The interest in the application of market discipline to regulate the financial industry has boomed recently due to the proposed New Capital Accord. This paper reviews the potential role market discipline can play in financial regulation. We start with a discussion of the rationale for financial regulation and with a brief history of the current regulatory mechanisms. Next, a definition of market discipline as a regulatory mechanism is advanced. We evaluate the disciplining power various market participants have. Finally, we argue that more external risk management disclosure is a condition sine qua non in order to enable market discipline as a regulatory mechanism. In this respect, the Basle Committee has taken the right approach.  相似文献

This paper presents a simple model which illustrates the possible policy- and welfare-implications of endogenous product selection in the postal sector. The cost of a unit of mail depends on its "quality" (e.g., speed of delivery) and on the type and location of the addressee (firms, urban households, and rural households). Senders have inelastic demands and differ in their willingness to pay for quality. Addressees are passive but their utility may affect social welfare. Two operators play a two-stage game, first choosing qualities and then prices. We first show that the equilibrium with two private (profit maximizing) operators results in an inefficient provision of quality. Then, we consider the mixed (Nash) equilibrium with one private and one (welfare maximizing) public operator. If the budget constraint of the public firm is not binding, this equilibrium is shown to be first-best efficient even if social welfare accounts for the utility of addressees. If the budget constraint is binding, the mixed equilibrium is not efficient but yields a higher level of welfare than the private equilibrium. Finally, we study the impact of minimum quality standards within our setting.  相似文献

Weber's thesis of the incompatibility of the Confucian ethos and rational entrepreneurial capitalism has been challenged by the economic miracles of many East Asian countries. One thesis presented here is that Confucianism is compatible with and has facilitated Asian capitalism by its influence on managerial values and practices. According to Weber, the release of tensions created by Calvinism was an important motivating force in the development of capitalism in the Occident. Confucianism offers a parallel mechanism to the profit-seeking drive in Western capitalism. We show that, in Confucian societies, there also exists tensions — in this case, between ideals and reality. These tensions are released through the Confucian concept of a ceaseless pursuit of renovation, a motivational mechanism for the development of capitalism in East Asian societies that parallels the West. Weber held that the classic model of bureaucracy, with impersonality at its core, is essential to the development and continuation of capitalism. Our second thesis is that humanism is an important element in Confucian bureaucracy and that humanistic bureaucracy can be both effective and efficient for the development of capitalism.  相似文献

PASSPORT OPTIONS     
We relate the theory of passport options with general principles from martingale theory as well as with the theory of Bessel processcs. The calculation of the price of a passport option leads to an equality between two norms on continuous martingales. We also solve the discrete time case for passport options.  相似文献
