PUT-CALL SYMMETRY: EXTENSIONS AND APPLICATIONS

Classic put-call symmetry relates the prices of puts and calls at strikes on opposite sides of the forward price. We extend put-call symmetry in several directions. Relaxing the assumptions, we generalize to unified local/stochastic volatility models and time-changed Lévy processes, under a symmetry condition. Further relaxing the assumptions, we generalize to various  asymmetric  dynamics. Extending the conclusions, we take an arbitrarily given payoff of European style or single/double/sequential barrier style, and we construct a conjugate European-style claim of equal value, and thereby a semistatic hedge of the given payoff.     

A Multidimensional Approach to the Influence of Environmental Marketing and Orientation on the Firm’s Organizational Performance

Since it implies a reduction in the quality and the quantity of the natural resources, environmental degradation is a present day problem that requires immediate solutions. This situation is driving firms to undertake an environmental transformation process with the purpose of reducing the negative externalities that come from their economic activities. Within this context, environmental marketing is an emerging business philosophy by which organizations can address sustainability issues. Moreover, environmental marketing and orientation are seen as valuable strategies to improve a firm’s competitiveness. However, the literature that has analyzed the link between environmental strategies and firms’ results has been inconclusive and contradictory. In this study, we propose and test a model that analyses how the implementation of ecological issues within a firm’s marketing strategy and orientation influences organizational results. Data were obtained through a survey sent to Spanish manufacturing firms. The results show that environmental marketing positively affects firms’ operational and commercial performance and this improvement will influence their economic results. Moreover, environmental marketing is revealed as an excellent strategy to obtain competitive advantages in costs and in product differentiation. Thus, this study agrees with the researchers who affirm that environmental strategies positively affect firm’s competitiveness while reducing environmental impact.     

农村市场信息供给失衡问题研究

文章从供给主体和需求主体的行为入手,分析了导致我国农村市场信息供给失衡的逻辑机理,从而得出我国自上而下的供给决策机制,导致的需求主体话语权缺失,需求评判机制失灵,供给主体动力不足,才是问题的根源。以此为逻辑起点,提出创立供求有效互动的服务模式,发挥需求评判的作用,真正建立起地方政府的内生动力,自觉地改善服务质量,从而促进农村市场信息供给失衡问题的有效解决。     

论支持农业保险发展的财政政策

农业保险是为农业生产者在从事农业生产过程中,对遭受自然灾害和意外事故所造成的经济损失提供保障的一种保险。它被视作推动现代农业,确保农业可持续发展的关键因素。发展农业保险不仅能促进农业发展和农业产品供给,还能减少农民收入波动,增进农民福利。近年来,农业保险越来越引起我国学术界和政府的高度重视,我国财政政策对于农业保险的支持的传统做法正面临改革创新的历史机遇。     

浅析我国地方税制运行情况与存在问题

随着1994年分税制改革的实施,我国初步建立了现行的地方税收制度。但由于受到当时的社会政治、经济条件的限制,分税制改革还带有明显的过渡性质,地方税制的设计与建设方面也就难免存在一定的缺陷。通过分析我国现行地方税制的运行情况以及地方税收入对地方财力的满足程度,提出我国现行地方税制存在的一些具体问题,希望在新一轮地方税制的改革中能引起足够的关注和重视,为尽快建立健全规范、完善、相对独立的地方税制贡献一份薄力。     

中国财政风险两大警戒线的测算研究

在国际金融危机仍在蔓延和深化的条件下,我国于2008年重启的积极财政政策将持续较长时间,但由此导致的财政风险将对积极财政政策能走多远产生重要影响.本文在模型推导基础上,对我国财政风险两大警戒线进行实证测算,认为运用<马约>中所谓的"国际警戒线"来判断中国财政风险状况并不科学合理.主要研究发现:(1)我国财政赤字率和公债负担率的警戒线分别约为4.05%、49.05%,这与<马约>中的财政标准有较大差异.(3)以测算出的财政风险两大警戒线为评判基准,发现目前我国财政风险状况尚处于可控的、安全的区间,如2008年我国实际的财政赤字率和公债负担率尚与警戒线值分别相差约3.68%和31.33%,即具有较大的政策回旋余地和操作空间.
