A note on the existence of unique equivalent martingale measures in a Markovian setting

Simple sufficient conditions for the existence of a unique equivalent martingale measure are provided. Furthermore, these conditions give us a handle on situations where an equivalent martingale measure cannot exist. The existence of a unique equivalent martingale measure is of relevance to problems in mathematical finance. Two examples of models for which the question of existence was unresolved are studied. By means of our results existence of a unique equivalent measure up to an explosion time is proved.

试论人文精神在2000版ISO9001质量标准中的蕴涵

近代管理科学的发展,经历了一个以"物"为中心的管理向以"人"为中心管理的转移过程。所谓 "管理的回归本色",其内涵是管理不是单纯的控制,而是一种如何使人的价值在组织的经营活动中得到实现 及如何尊重人的价值。这一理论视角的转换,在改版后的2000版ISO9001标准中得到了鲜明的体现和阐释。

Foods produced using biotechnology: how does the law protect consumers?

This paper addresses the following subjects: biotechnology and consumers, concern about risks, consumer acceptance, labelling of foods produced using biotechnology, the legal approach to consumer protection, and consumer protection policies relating to biotechnology products in the European Union, the United States, Turkey and global institutions such as the Convention for Biological Diversity (CBD) and the World Trade Organisation (WTO). It is likely that biotechnology will gain ground much more rapidly in the twenty‐first century than in the past. Despite rapid, detailed and precise advances in gene technology, its applications have not been the received with a great deal of consumer enthusiasm. Consumers have approached genetically modified foods with considerable apprehension and opposition. Consumer concerns about bioengineered food products focus on the questions of human health, environmental and social risks and benefits. The most important stages in the process of marketing new foods produced using biotechnology are to demonstrate user need and consumer acceptance. Generally, the technical complexity of biotechnology makes it difficult for consumers to understand details of the product and the specific attributes of biotechnology applications. Scientific uncertainty, the nature of consumer concerns and general reluctance to accept biotechnology products, increase the importance of consumer protection. Legal protection is a very important factor in the solution of new social problems related to technological advances. More specifically, consumer and environmental law support consumer protection related to foods produced with biotechnology. The basic principles of consumer law can be re‐formulated as consumer rights. Environmental law is a new phenomenon, but precautionary principles and public participation in decision‐making for environmental law are relevant to consumer protection relating to bioengineered food products.     

相互制农业保险在我国的困境及适用性

相互制保险在农业保险领域有着明显的优势。然而,相互制保险管理制度上的缺陷及其与农业保险的矛盾制约着相互制农业保险的发展。目前,在我国合作意识不强、农村合作经济组织发育不健全的情况下,开展相互制农业保险还有一定困难。因此,要开展相互制农业保险,必须选择合适的范围和地区,并对相互制保险进行制度创新,为相互制农业保险提供财政补贴,建立再保险机制,加强引导,减少行政干预。
