Potential impacts of sustainable intensification and diversification options for agriculture-based livelihoods in Buxa, West Bengal, India, were evaluated using bioeconomic modelling. The baseline scenario involved multiple cropping seasons and a combination of crops on 0.9 ha land-holdings, livestock husbandry, and exploitation of common property resources. With capital costs of Rs.128,180 (US$2293) and annual operating costs of Rs.37,290 (US$667), the net benefit generated (excluding depreciation) was Rs.70,250 (US$1257) annually. The pay-back period was 1.8 years, and the internal rate of return (IRR) was 53.7% over 10 years. Allocation of 20 days annually to fishing increased the net benefit to Rs.75,030 (US$1342) and IRR to 56.5% with minimal added costs and risks. Adopting the system of rice intensification (SRI) for paddy cultivation on 0.35?ha increased the IRR to 61.1%, while reducing agrochemical and inorganic fertilizer use. Including small-scale fish culture in a 0.1 ha pond integrated in the irrigation scheme for SRI cultivation resulted in an IRR of 77.3% and reduced the pay-back period to 1.3 years. Some risks to biodiversity are apparent with each scenario; however, with appropriate safeguards, sustainable agricultural intensification and livelihoods diversification could bolster agrobiodiversity and social-ecological resilience of highland communities, while alleviating pressure on biodiversity.  相似文献

Abstract

This paper applies Narver and Slater's (1990 Narver, J. and Slater, S. 1990. The effect of a market orientation on business profitability. Journal of Marketing, 54(2): 20[Crossref], [Web of Science ®] [Google Scholar]) conceptualisation of market orientation to non-profit organisations. The study constructs a reliable and valid scale of the market orientation in non-profits in order to test the relationship between non-profits' market orientation and their performance outcomes in the context of a developing country. We surveyed 211 Indian non-profits and received 102 usable responses. We used principal axis factoring with oblique rotation to analyse the data. The scale was tested for its dimensionality, reliability, and various validities. The findings show a positive link between non-profits' market orientation and their performance in the context of a developing country. Market-oriented non-profits were found to be more effective in achieving their organisational mission, beneficiary satisfaction, and peer reputation than those that were less market oriented.  相似文献

We investigate the effects of exchange rate changes on innovation by a multinational corporation. The firm enjoys a monopoly in the home market but engages in Cournot competition with a domestic firm in the foreign market. Changes in currency values affect the multinational firm’s profits in domestic currency units, and thus influence the optimal level of process innovation as well as output and prices in the two markets. We find that a devaluation of the home currency will lead the home firm to increase its output in both the home and foreign markets, and increase its spending on R&D. We also find that currency devaluation in the home market leads to lower prices in both markets.  相似文献

Open innovation, defined as a firm's purposive pursuit and integration of external inputs for new product development, offers an alternative perspective on innovation. Drawing on resource-based and capability theories, this study identifies key factors that enable inbound open innovation and increase its efficacy in a business-to-business context. Because open innovation relies on external connections, relational capability—that is, the firm's ability to make and manage relationships with other firms—should enhance the effects of inbound open innovation on firm performance. Two key resources may further enhance the moderating effects of relational capability: network spillovers that indicate knowledge-rich surroundings, and flexibility that allows for responsiveness and adaptability. The authors test these relationships with data from managers in 204 business-to-business high-tech firms, as well as secondary data pertaining to firm performance and flexibility. The results support the expectations that the ability to build interfirm relationships in a knowledge-rich environment increase the efficacy of inbound open innovation for gaining superior financial performance. Interestingly, additional analyses suggest an unexpected nonlinear interaction effect with flexibility. When firms possess strong relational capabilities and adopt an open innovation approach, they achieve higher financial performance if they have a low or a high level of flexibility. The theoretical and managerial implications of these findings are discussed.  相似文献

Past TQM literature has been inconclusive in resolving the validity of the universalistic approach versus the contingency approach of TQM implementation. In this paper we contribute to the resolution of this debate by using a total effects approach within the contingency perspective. We propose a culture-quality system design-outcomes framework for TQM implementation. We then use this framework to study the differences in total effects relationships among TQM constructs across four contingencies, firm size, TQM duration, unionization, and industry type. Data from a sample of 394 plants (SIC codes 20 through 39) are used to test the validity of our contingency model. Our results revealed that firm size, TQM duration, and industry type moderate the influence of total effects of culture (top management commitment, customer focus, and trust) on final outcomes (process quality, product quality, and customer satisfaction). These contingencies also moderate the influence of total effects of quality system design (design management, training, empowerment, quality information usage, supplier quality management, and process quality management) on final outcomes. The strongest contributor to variation in total effects across groups was industry type, followed by size and then TQM duration. To a lesser extent, unionization was a moderator in total effects relationships. These findings uniquely contribute to the emerging contingency theory of TQM implementation.  相似文献

Where Do Australians Invest?   总被引:2,自引:0,他引:2  
In this article, we analyse the geography of Australia's international portfolio investment using the International Monetary Fund's Co‐ordinated Portfolio Investment Survey dataset. Preliminary results suggest that Australia's external holdings of equity and debt as a percentage of national income almost doubled between 1997 and 2001. However, Australia's international investment position as a percentage of national income is one of the lowest amongst the major OECD countries. In 2001 approximately two‐thirds of Australia's total investments were in the United States and the United Kingdom. By contrast Australia's trade share (exports plus imports as a percentage of Australia's total world trade) with these countries was approximately 20 per cent in the same year. The major determinants of Australia's geographical allocation of portfolio investment indicate a broad correspondence between stock market capitalisation of destination countries and the allocation of Australian financial investments but with some deviations from that baseline, where the deviations are correlated with Australian trade patterns.  相似文献

Our study of 134 North American and European ski resorts examines the influence of externally focused organizational capabilities on the generation of proactive environmental strategies under contingent effects of uncertainty in the general business environment. We find that the capabilities of strategic proactivity and continuous innovation are associated with proactive environmental strategies. Managerial perceptions of uncertainty in the general business environment moderate the deployment of the capability of continuous innovation at all levels of uncertainty and stakeholder engagement at low and average levels of uncertainty. The study contributes to the resource‐based view (RBV) by illuminating an important contingency under which capabilities are likely to be deployed to generate a proactive corporate strategy.

This paper examines local responses to potential ecotourism development in the Tawushan Nature Reserve located in southeastern Taiwan. Community attitude and intention toward four dimensions of ecotourism, including conservation of natural resources, preservation of cultural tradition, sustainable community development, and participation in ecotourism planning and management, were measured. Furthermore, the paper examines whether or not there is congruence between community attitude and intention toward ecotourism development. Analysis is based on data collected using face-to-face questionnaire interviews in two indigenous communities consisting primarily of the Paiwan ethnic group. The study findings show that local people hold generally positive views of the measures necessary to achieve ecotourism; however, their intentions to engage in behaviors to support these measures do not entirely match with their positive views. This suggests that while local residents may support ecotourism development based on international guidelines, their intentions to act will depend on local environmental, social, and politico-economic conditions. It is suggested that issues related to community empowerment, relationship between government and communities, value conflicts introduced by ecotourism development, and the dynamics among and between various community groups will need to be addressed if positive community intention to participate in ecotourism is to be encouraged.  相似文献

Do market participants evaluate the credibility of a firm's share repurchase announcement based on the firm's share repurchase history? Using a sample of 1,507 share repurchase programs for firms listed on the Toronto Stock Exchange from 1994 to 2005, we find that 69% of firms fail to acquire the target number of shares specified at announcement and many firms fail to repurchase any shares. We develop credibility indices and find a positive relationship between current announcement abnormal returns and completion credibility of previous announcements. We conclude that the market prices completion credibility of past share repurchase announcements in reacting to current repurchase announcements. Copyright © 2010 ASAC.

Using a model with moral hazard and bankruptcy costs, we show that the direction of intertemporal trade between countries depends on differences in their autarkic distributions of wealth. We also examine the consequences of redistribution policies and bail‐out policies in this framework. We show that, in the presence of bankruptcy cost and capital market imperfections due to moral hazard, the very rich and the very poor do not undertake any risk and choose to be passive lenders. Only individuals whose wealth lies within an intermediate range choose to become entrepreneurs. Redistributive policies influence the supply of entrepreneurship and autarkic interest rates.  相似文献
