Environmental issues are restructuring markets and redirecting capital flows throughout the world. An outline is provided of concerns facing the development of an environmentally responsible or ‘environmental finance’ perspective. It reviews the major ways in which organizations are responding to environmental threats and opportunities in the three major branches of finance — corporate finance, investments and financial institutions — highlighting in particular novel programs and initiatives. In the past, financial concerns have exacerbated the degradation of the natural environment; in the future, they probably hold the key to their preservation.  相似文献

Input price variability is an important source of risk for corporations that process raw commodities. Models of optimal input hedging are developed in this paper based on the maximization of managerial expected utility. The relationship between hedging strategies and output decisions is examined to assess the impact of the ability to set output prices on futures market participation. As a firm's ability to set output prices diminishes in the short run, input futures positions increase although the optimal hedge ratio may either increase or decrease. For a perfectly competitive firm, however, shifts in output price caused by input price changes provide a natural cash market hedge of input price risk and reduce the firm's optimal input futures position.  相似文献

近年来,世界各国民主化的趋势使得学者们必须面对两个具有潜在矛盾的目标:其一是建立一个能涵盖各个国家不同经验、具有多样性的民主概念;其二是在不扩大概念的基础上扩大对这一大类案例的分析。本文认为这种双重挑战导致了概念创新的加速,产生了几百种民主的亚类型———也就是“带形容词”的民主。本文对出现的三种重要创新类型的优势和弱点进行了探讨,这三种类型是:对民主定义的“精确化”;对与民主相关联的大概念进行转化;以及建立不同的亚类型。鉴于这些重新定义民主概念的策略所产生的含义具有复杂的结构,我们显得老生常谈式的结论其实具有新的紧迫含义:学者们必须通过对他们所使用的民主概念进行清楚的定义和说明来为自己的研究定位。  相似文献

This paper develops and empirically tests a model of crime deterrence in an urban area. There are two important departures from past efforts to study the impact of criminal sanctions. The first is that the provision of sanctions from the local public sector is modeled; this is accomplished by specifying the distributional goals of local government and by specifying the production of safety. The second departure is that actual crime and reported crime are differentiated theoretically and in the empirical work. An empirical test of the model, using a unique neighborhood data set, shows that police deter crime significantly; however, this deterrent impact cannot be demonstrated without the distinction between actual and reported crime.  相似文献

Geocaching is a modern-day version of “hide and seek” where participants use geographical longitude and latitude coordinates to locate a “geocache” using a GPS device or mobile app. An agriculturally focused geocache program could foster tourism, interest and educational opportunities about rural and agricultural areas, and could facilitate additional patronage of businesses that operate in these areas. As a prerequisite to such a program, however, organizations must commit to establishing and maintaining a geocache. This study explores the perceived benefits and constraints to an organization's participation in a rural or agriculturally focused geocache program. A case example of an agriculturally focused geocaching program, AgCache, is used as a starting point. In-depth interviews of program Founders and current participants explored the program's background and goals, and experiences of participating sites. Complimenting this, a survey collected information from potential host sites, and probit model analyses were used to assess influences on an organization's interest in hosting a geocache. While many organizations indicated that they would be interested in such a program, several indicated (addressable) concerns. Characteristics of the organization and respondent were found to significantly influence their interest. Findings are instructive for targeting and recruiting organizations into an agricultural or rural geocaching program.  相似文献

We develop a monopolistic competition model to investigate effects of international technological convergence on factor rewards, output composition, and welfare. Comparative static analysis indicates technological convergence improves the follower's—but impairs the leader's—international competitiveness. The leader's welfare improves unambiguously; the follower's welfare depends on the relative strength of convergence's income and terms-of-trade effects. We use data from seventeen food industries in thirty countries, 1993–2001, to test these analytical predictions. Evidence of convergence is found in thirteen of seventeen industries. Convergence lifts followers' relative wages and global value-added shares. Followers benefit from convergence's positive income effect. Leaders benefit from higher terms of trade.  相似文献

The effectiveness of community-based extension approaches has been widely documented, however their sustainability remains weak. Institutionalization has been proposed as a way of achieving sustainability. This paper shares experiences of the learning and planning phase of the institutionalization of the volunteer farmer-trainer (VFT) approach in three dairy producer organizations (POs) in Kenya. The paper builds a detailed understanding of the key steps and social processes involved and the wider lessons that might be learned regarding institutionalization in the context of local institutions such POs. We draw on data from key informant interviews, focus groups discussions and workshops. The first phase of the process which spanned one year involved engagements with stakeholders at different levels; from VFTs, dairy cooperative management, government extension and local NGOs. The process involved awareness creation, joint learning at the individual, group and organization level, a strengths-weaknesses-opportunities-threats (SWOT) analysis of producer organizations and identifying opportunities for harnessing resources for support functions. We highlight the important supporting social and institutional processes that are required for this to happen. These include getting acceptance and support from key stakeholders, developing a shared understanding, stakeholder ownership of the process, commitment from top leadership of POs and institutional structures to support the process. For the process to be actualized, we discuss mechanisms that need to be put in place.  相似文献

Social TV is the use of communication devices to connect with family and friends watching other TV screens. Plausible arguments suggest both positive and negative effects of social TV viewing on ad-effectiveness. This study contributes by providing evidence for the direction of social TV's effects. The results of a controlled laboratory experiment suggest that the benefits of social TV, principally its association with live TV and therefore less ad-avoidance, come at the cost of negative distraction effects. Like normal coviewing, social TV viewing distracts from ad-processing, reducing unaided recall and brand attitude favorability, compared to individual (solus) viewing. However, social TV messaging about ads improved brand attitude. Perceived creativity increased the likelihood of ad-related messaging. Social TV also has an additional source of distraction, multitasking, but in this study, multitasking did not further reduce ad-effectiveness compared to coviewing. The paper concludes with implications for advertisers and future research.  相似文献

As a subset of the international business literature, cross-border equity based partnerships have drawn significant academic attention. In the context of inter-firm partnerships, the power dynamics between parties and the implications that power has on the relational dynamics between firms is an important consideration. Research that connects power with network theory has recently emerged, suggesting that the network, as a source of power, plays a significant role in inter-firm dynamics. Yet, while there has been a substantial body of work either articulating the antecedents and consequences of power, little research has paid attention to the role that power plays in international JV formations; this presents a significant gap in the international business literature. Consequently, this study investigates the role that global network structure plays in the formation of new equity based international partnerships. Secondly, it contributes to the international JV literature by developing and testing a theoretical framework that examines inter-firm power dynamics as derived from the network position of each firm in the global network. Global network prominence, brokerage and weakness are key factors utilized in the analysis. The hypotheses are tested using a global manufacturing joint venture longitudinal dataset that contains 985,689 observations from 1985 to 2003. The results of the event history analysis indicate that for the manufacturer global network prominence, brokerage and weakness play an important role in new joint venture formations. On the other hand, only global network prominence is a significant factor for the potential partner.  相似文献
