Drawing on the eco-innovation and resource-based view, this research attempts to contribute to the eco-innovation-performance debate by examining the effects of eco-innovation on business performance. In particular, we propose that the eco-innovation–performance relationship is contingent on environmental orientation and resources commitment. The analysis of 83 green-oriented SMEs in New Zealand suggests that eco-innovation has a positive effect on business performance. More interestingly, the findings show although environmental orientation does not directly influence business performance, it enhances the positive effect of eco-innovation on business performance. The results further suggest that green-oriented firms will reap more performance benefit of eco-innovation when they commit more organizational resources.  相似文献

Starting from a comparison of Josef Steindl's observations on the problems of the financing of small firms, with the implications of the Modigiani – Miller approach to financial structure, this paper investigates relationships between financial leverage and operating leverage by the application of option pricing theory to the value of a firm's debt. Drawing on possible differences between the second-hand break-up value and the present value of the flow of earnings from a firm's assets, it suggests linkages between production structure and firm financial structure. It then extends these results to resolving the problems of providing market financing for the creation and evolution of small firms in industrialized and transforming economies.  相似文献

The personal and emotive context of visitors’ experiences has been neglected in much sustainable tourist attraction management. This paper applies ASEB demi-grid analysis as a consumer-orientated management tool to facilitate an understanding of the beneficial experiences gained by international visitors to a penguin-watching tourism attraction on the Otago Peninsula, New Zealand. Forty in-depth interviews with visitors showed that the main beneficial experiences gained included reported enhanced environmental awareness (cognition) and ‘mood’ benefits (affection). In addition, several consistent themes emerged from the beneficial experiences reported by tourists, including issues related to viewing, proximity, authenticity and wonder. Findings thus included the perceived importance of visitors to be able to view endangered penguins ‘up close’ in their natural habitat to elicit feelings of exploration and privilege, to appreciate the simplicity and naturalness of the setting and to increase their knowledge of the species through interaction with an experienced guide.  相似文献

The systematic adoption of the eXtensible Business Reporting Language (XBRL) for financial reporting represents a great challenge. Worldwide, a large number of regulators are making an effort to promote the adoption of this standard to simplify and enhance the communication of financial information. This requires the definition of well‐structured taxonomies that can standardize and accommodate the content of financial reports prepared by firms. This study aims to analyze the regulator‐led adoption of XBRL for financial reporting. It examines the XBRL taxonomies used by Italian firms to reflect their financial reporting under rule‐based Italian GAAP and principles‐based International Financial Reporting Standards (IFRS). We compare the alignment of the Italian GAAP taxonomy and the IFRS taxonomy with Italian companies' financial statements and find two different levels of fit. The results offer useful insights for regulators and policy makers in prescribing or establishing appropriate taxonomies. We illustrate the potential impacts of the different taxonomies on the quality of financial reporting in terms of comparability and potential loss of information.  相似文献

In this paper I argue that political economy considerations and, in particular, the identity of the reformers, are central to understanding the Argentine crisis that culminated in sovereign default in January 2002. During the 1990s, the main political parties remained attached to populism, and no strong party emerged at the center of the political spectrum. This had two effects in the reform process. First, it severely deteriorated it (efficiency, corruption), reducing the support of the population. Second, when a series of shocks hit the economy the anti‐reform camp tried to undo most reforms, and thus convey a message to the population about the “right” model of the world.  相似文献

We present evidence on whether and how a household's behavior is influenced by the presence and characteristics of its extended family. Using data from the PROGRESA program in Mexico, we exploit information on the paternal and maternal surnames of heads and spouses in conjunction with the Spanish naming convention to identify the inter- and intra-generational family links of each household to others in the same village. We then exploit the randomized research design of the PROGRESA evaluation data to identify whether the treatment effects of PROGRESA transfers on secondary school enrolment vary according to the characteristics of extended family. We find PROGRESA only raises secondary enrolment among households that are embedded in a family network. Eligible but isolated households do not respond. The mechanism through which the extended family influences household schooling choices is the redistribution of resources within the family network from eligibles that receive de facto unconditional cash transfers from PROGRESA, towards eligibles on the margin of enrolling children into secondary school.  相似文献

This article reports exploratory research about tendencies toward postmaterialism in university students. This paper used the theoretical framework proposed by Inglehart regarding three categories of leisure: postmaterialist, materialist and common. Students from a Spanish university (N = 1036) completed questionnaires that evaluated their materialist-postmaterialist values, how often they practiced the activities included in each category of leisure and the motivational factors involved in them. The results revealed that university students showed a tendency toward postmaterialism. Further, relationships were found between materialist-postmaterialist values and categories of leisure. This study results suggested that the tendency toward postmaterialist values may be a factor in structuring the leisure patterns of young Spanish university students.  相似文献
