Policy action to halt the global loss of biodiversity and ecosystems is hindered by the perception that it would be so costly as to compromise economic development, yet this assumption needs testing. Inspired by the recent Stern Review on the Economics of Climate Change, the leaders of the G8+5 nations commissioned a similar assessment of the economics of losing biodiversity, under the Potsdam Initiative on Biodiversity. Here, we propose a conceptual framework for such a global assessment which emphasizes several critical insights from the environmental economics and valuation literature: contrasting counterfactual scenarios which differ solely in whether they include specific conservation policies; identifying non-overlapping benefits; modeling the production, flow, use and value of benefits in a spatially-explicit way; and incorporating the likely costs as well as possible benefits of policy interventions. Tackling these challenges, we argue, will significantly enhance our ability to quantify how the loss of benefits derived from ecosystems and biodiversity compares with the costs incurred in retaining them. We also summarise a review of the current state of knowledge, in order to assess how quickly this framework could be operationalized for some key ecosystem services.  相似文献

The aim of this paper is to critically analyse the literature published from 2002 to mid‐2015 on disclosures of goodwill and their respective impairment tests; identify the main contributions of the literature, as well as its limitations; and suggest new approaches for future research. We also present a summary of the main determinants of disclosures on goodwill in the literature as well as the still scarce studies’ conclusions of those disclosures in the market. After a review of the literature, we discuss the need to reinforce enforcement mechanisms, so as to improve the level of compliance of disclosures on goodwill and their impairment tests. The majority of the analysed literature reveals that the information disclosed about goodwill is incomplete and largely heterogeneous, indicating a reduced level of compliance with the disclosures required by accounting standards. The paper may support the development of future empirical studies about goodwill's disclosures, which will bridge the identified gaps in the literature.  相似文献

The role that the resources and capabilities of agricultural entrepreneurs play on both environmental performance (EP) and financial performance (FP) is still unclear. This study analyzes how small farms enhance EP and FP in an inland Portuguese region through the relationship between dynamic capabilities (DCs), entrepreneurial orientation (EO), and environmental sustainability commitment (ESC). Based on a sample of 160 fresh fruit farms and applying a partial least squares structural equation modeling (PLS-SEM), our study concludes that EO and ESC influence EP and FP positively. Hence, farms can achieve competitive advantage through mitigating their profound impacts on the environment as proposed by the natural resource-based view (NRBV). Farms are also improving DCs, but farmers respond to the higher environmental requirements of agricultural markets primarily through research and development (R&D) capabilities and not through marketing capabilities. Having as theoretical supports the NRBV and the DCs, our study contributes to a better understanding of the mechanisms through which entrepreneurs enhance EP and FP in sectors with high environmental impacts such as agriculture. The findings suggest that entrepreneurship training projects may enable farmers to approach food security as a market opportunity and not only as rules they must follow.  相似文献

Corporate Social Responsibility is a reality for businesses and can be understood through the analysis of organizational actions in three areas, namely: economic, social and environmental. Its operationalization occurs through projects, and cases presented by the literature can greatly contribute to the definition of factors that lead these projects to success. Generally, professionals and entrepreneurs have good qualifications in traditional aspects of project management, but when they need to manage Corporate Social Responsibility projects doubts arise. In this context, the main objective of this study was to analyse the most impactful Critical Success Factors for Corporate Social Responsibility projects, considering Brazilian companies’ context, and to propose guidelines to better qualify new professionals and entrepreneurs in the kind of projects mentioned. Thirteen Critical Success Factors were identified in the literature and, through a survey with experienced professionals, it was possible to evidence the six most relevant for Brazilian companies’ context: ability to properly define the scope; ability to integrate the CSR project with the company's strategy; ability to identify stakeholders’ needs; ability to analyse risks; identify and involve stakeholders outside the organization; and grant financial resources to meet project needs. Using the information provided, three guidelines were proposed to better qualify professionals and entrepreneurs. This is an exploratory study that can contribute to potentialize debates on theme.

While firms' engagement with Corporate Social Responsibility has been associated with positive performance impacts, little is known about the incorporation of the United Nations 2030 Agenda into business practices. Precisely, although the literature suggests that firms are pursuing the Sustainable Development Goals (SDGs), there are limited insights on their strategy to implement them in the context of developing countries. To address this gap, we conducted a comprehensive large-scale investigation of 2030 Agenda adoption by Brazilian companies. Accordingly, the analysis of our multicase study reveals (1) variations on the business opportunities brought by the SDGs depending on the firm position in the value chain, (2) which SDGs and target stakeholders are addressed through corporate policies and practices, (3) the different ways firms embrace the SDGs to pursue ambidexterity. Our findings clarify how firms in the developing countries interpret the institutional pressures and assemble their internal resources to respond to the SDGs challenges. Boundary conditions and policy implications are further discussed.  相似文献

This paper analyses the limit distributions of the seasonal unit root test procedures proposed by Dickey, Hasza and Fuller (1984) and Hylleberg, Engle, Granger and Yoo (1990), when local trends at different frequencies are present in data generation processes, but ignored in the test regressions used. The findings presented explicitly show that neglected deterministic trends have negative effects on the distributions of the test statistics. Analytical observations and Monte Carlo simulations reveal that seasonal unit root test statistics become severely undersized as the values of standardized local trends increase. Hence, failure to consider local trends may often bear the undesirable effect of biasing decisions towards non-rejection of unit roots.Received: February 2001, Accepted: September 2001, JEL Classification: C12, C22Paulo M.

This study develops an ex-ante model for estimating financial distress likelihood (FDL), and contributes to the literature by presenting a financially-based definition of distress that is independent of its legal consequences, a theoretically supported model for the FDL, and an appropriate methodology that uses panel data to eliminate the unobservable heterogeneity. The model is then estimated cross-sectionally to obtain an indicator of the likelihood of financial distress that incorporates the specificity of each company. In doing so, this study provides a well-specified model that is stable in terms of magnitude, sign and significance of the coefficients and, more importantly, that yields a measure of the FDL that is more robust to time and the international context than the estimates of FDL that are based on seminal models. This measure could be appropriate for use in future research that deals with FDL, such as capital structure and the prevention of financial distress.  相似文献
