The restructuring of the financial landscape that has occurred in the last three decades, has led to a reassessment of co‐operative models of organization. An outcome of this process has been the demutualization of mutual financial organizations. Using a case study approach this paper analyses the pressures on mutual structures encountered by Australian mutual life insurers. Such an approach provides a number of insights into the way in which firms adjust to changes in regulatory and competitive environments. It is concluded that a number of exogenous and endogenous forces combined to drive the process of organizational change.  相似文献

Retailers’ assortment rationalisation strategies have found an “ally” in the current global economic crisis. Indeed, retail boycotts of individual brands in economic recession contexts are not uncommon in the CPG industry. In fact, many of the consumers who began buying PLs during the economic recession are continuing their PL behaviour post-recession. So, what is the role of the economic climate in consumers’ reaction– in terms of store loyalty – to retailers’ NB delisting decisions? Is it so relevant? This paper examines how consumers’ attitude towards the economic climate influences his/her reaction to retailers’ strategy of offering ‘PL-only’ assortments in the context of an economic slump (Spain) compared to a context of economic recovery (U.S.). To do so, we have designed a controlled online experiment for two large consumer panels in the Spanish and the U.S. markets. Our results suggest that consumers’ acceptance of ‘PL-only’ assortments is a separate phenomenon rather than merely being a “consequence” of the current economic situation. Nevertheless, in an economic recovery, such ‘PL-only’ assortments do not appear to be the best strategy.  相似文献

This study enhances our understanding of the complex relationship between diversity and employee retention. The study found that positive perceptions of an organization's “diversity climate” were related to decreased turnover intentions and found support for the proposition that calculative attachment mediated this relationship. In addition, the study considered potential interactions with diversity climate perceptions in predicting calculative attachment and found support for satisfaction with pay as a moderator, but not supervisor effectiveness. Finally, the study determined that the benefits of a positive diversity climate may extend to all employees, including White men. ©2011 Wiley Periodicals, Inc.  相似文献

In recent years, numerous articles have addressed management strategies aimed at assisting forests to adapt to climate change. However, these seldom take into account the practical and economic implications of implementing these strategies, notably, supply of forest plants and seed. Using semi-structured interviews with practitioners involved in the plant and seed supply chain in Great Britain, we highlight a series of practical and economic bottlenecks commonly encountered in the supply of locally sourced seed and domestically produced planting stock for native woodland and hedging markets. We find that adoption of alternative seed sourcing strategies, designed specifically to account for directional climate warming, is likely to exacerbate existing problems by adding further complexity to decisions nurseries make about tree species and seed origins to produce. The lack of long-term market predictability brought about by the current configuration of forestry grants and regulations and, in particular, the administrative systems for processing grant applications is identified as a major impediment to having a sustainable and competitive supply of home-grown and currently adapted planting stock. Finally, the time and effort it takes to supply healthy plants for native woodland creation projects deserves much wider recognition throughout the industry and will be crucial if planting objectives are to be met sustainably.  相似文献

Shortfalls in global food production, coupled with the growing visibility of climate change's disruptive effects, have underlined for many observers the importance of devoting rural lands to their ‘optimal’ use, where they can make maximal contributions to the global imperatives of feeding the human population and maintaining vital environmental services. In this context observers have endorsed rural land use planning as a way to insure that, at least in theory, lands get devoted to their best uses. In practice, land use planning in the developing world has resembled ‘organized anarchy’. Small landholders with insecure land tenure, overseas investors seeking large land deals, NGOs representing indigenous peoples, government officials, and staff from international environmental NGOs and multilateral organizations have come together in strategic action fields to struggle over and sometimes negotiate land use plans for contested landscapes. These plans represent a strategic, spatially explicit response to the climate change–biodiversity–food security crisis.  相似文献

The conservation and management of protected areas in urban settings has become increasingly challenging with dynamics over land use change in adjacent urban areas being highly relevant to, but at times conflicting with, the protected area. This study seeks to better understand the implications of land use change processes to urban protected area management through the case study of the Las Piñas – Parañaque Critical Habitat and Ecotourism Area (LPPCHEA) in Metro Manila, Philippines. Factors and processes influencing land use change and protected area management and the impact of stakeholders’ perceptions on protected area were analyzed. The urban protected area in itself has limited influence on its surrounding urban areas, as land use change in these areas is shaped more by social, economic and policy/institutional factors occurring within the context of urban-regional development. The study also found that land use conflict is evident in an urban protected area due to the competing ecosystem services derived by various stakeholders. This discord is deepened by the lack of coordination between land use planning and protected area management. Integrating protected area management with land use planning through legally binding instruments, specific timeframes and clear internal procedures can help resolve land use conflict for an urban protected area at the strategic or policy level.  相似文献

This paper investigates the relationship between environmental regulations and innovation by focusing on the automobile industry in a cross-country setting. We provide empirical evidence that the presence of agency problems mitigates the negative effects of environmental regulations on overall R&D activity, which leads to full compensation when the degree of agency problems is sufficiently high. Guiding our empirical analysis, we provide a general model consistent with the structure of existing ownership data. Specifically, we model ownership structure as a combination of two extreme corporate governance types. On the one extreme there are profit maximizers, and on the other extreme there are managers who are only concerned with their private benefits. The model leads to a simple country level ownership indicator and shows that if an economy is dominated by firms with higher agency problems, then pollution tax might even increase overall R&D, while reducing pollution. According to our estimations, such an outcome is possible only for out-of-sample values of the ownership indicator, where the degree of agency problems is extremely high.  相似文献

Land use change is strongly modifying the traditional landscape of hilly productive Mediterranean sites. An example of these circumstances is the Langhe region (Piemonte, NW Italy), where woody plantations such as vineyards and orchards have been cultivated on hillslopes for centuries. In this paper we assess landscape changes occurred in the Diano study area (2651 ha) in the 1954–2000 period and we ascertain land use transition paths and rates of this rural ecosystem. Land use mapping obtained from object-oriented analysis of aerial photographs was used to quantify land use changes between 1954 and 2000. To examine the spatio-temporal patterns of land use change over time, a set of spatial statistics capturing different dimensions of landscape change was identified. An increase of landscape heterogeneity from 1954 to the present was observed due to the expansion of orchards and the fragmentation of field crops. A significant portion (55%) of current orchards surface is represented by former field crops, 24% by vineyards and 15% by forests. The strong expansion of hazelnut orchards concurred to the fragmentation of traditional rural landscape was dominated by vineyards, field crops and forests. Hazelnut orchards expansion was mainly located in places where grapes cultivation was less remunerative. A further expansion of hazelnut in the area should be planned, discussed and carefully monitored through change detection studies in order to avoid potential unsustainable use of the land.  相似文献

Recent non-parametric statistical analysis of high-frequency VIX data (Todorov and Tauchen, 2011) reveals that VIX dynamics is a pure jump semimartingale with infinite jump activity and infinite variation. To our best knowledge, existing models in the literature for pricing and hedging VIX derivatives do not have these features. This paper fills this gap by developing a novel class of parsimonious pure jump models with such features for VIX based on the additive time change technique proposed in Li et al., 2016a, Li et al., 2016b. We time change the 3/2 diffusion by a class of additive subordinators with infinite activity, yielding pure jump Markov semimartingales with infinite activity and infinite variation. These processes have time and state dependent jumps that are mean reverting and are able to capture stylized features of VIX. Our models take the initial term structure of VIX futures as input and are analytically tractable for pricing VIX futures and European options via eigenfunction expansions. Through calibration exercises, we show that our model is able to achieve excellent fit for the VIX implied volatility surface which typically exhibits very steep skews. Comparison to two other models in terms of calibration reveals that our model performs better both in-sample and out-of-sample. We explain the ability of our model to fit the volatility surface by evaluating the matching of moments implied from market VIX option prices. To hedge VIX options, we develop a dynamic strategy which minimizes instantaneous jump risk at each rebalancing time while controlling transaction cost. Its effectiveness is demonstrated through a simulation study on hedging Bermudan style VIX options.  相似文献
