ABSTRACT

The benefits of biofuels depend on the feedstock, conversion pathway and local context. This paper assesses biofuels technology readiness and developments to provide foresight to biofuels development in Southern Africa. Efficient conversion pathways, coupled with biomass from waste or high-yielding energy crops, will reduce both the costs of biofuels production, and the environmental impacts. Compared to petroleum fuels, the current commercial biofuels (ethanol, biogas and biodiesel) typically offer carbon emission reductions of 30–50% but are marginally more expensive. The extent of biofuels market penetration will therefore be influenced by mandates (blending targets) and subsidies (green premium). Advanced biofuels promise greater efficiencies and carbon emission reductions at reduced cost but will require further research and development to reach commercialisation. If developed appropriately, biofuels can reduce carbon emissions and improve energy security, while enabling sustainable agriculture and improved natural resources management.  相似文献

This article uses information on out‐of‐pocket housing cost and house price appreciation along with the geo‐coded version of the Panel Study of Income Dynamics to consider the differences in the impact of these and other variables on the tenure choices of sample households across three time periods, the 1970s, the 1980s and the 1990s. Specifically, an extended continuous time probability model is used to examine households' transitions from renting to owning and subsequent possible transitions either back to rental tenure or to another owned home during our three observation periods. Coefficient estimates show that financial variables such as house price appreciation and out‐of‐pocket housing cost play an important role in determining all the transitions. In addition, the analysis demonstrates the interesting result that the cumulative likelihoods of homeownership derived from the model are consistently lower than the probabilities of an initial transition to homeownership from rental tenure during the observation period. Finally, the magnitude and timing of the impact on homeownership of a policy experiment that eliminates the mortgage interest deduction are shown to differ substantially across the three decades.  相似文献

This paper examines the uses of humour among participants in five bank training programmes in the UK. These programmes, run by the banks themselves, were studied using ethnographic methods and the observations reported here are based upon extensive field notes. The paper examines the ways in which participants deployed humour during these learning events and the role humour played in the management of their relations with their fellow learners and the course instructors. The course instructors' use of humour is also examined. It is argued that humour played a far from trivial role in the programmes studied. On the contrary, humour was vital to their maintenance as viable organizational practices. In conclusion it is suggested that the more systematic study of humour could make an important contribution to the understanding of the social realities of corporate training programmes.  相似文献

This review of K. Camfferman and S. A. Zeff, Financial Reporting and Global Capital Markets: A History of the International Accounting Standards Committee, 1973–2000 (Oxford: Oxford University Press, 2007) provides an overview of the work, comments on the authors' approach to the history of the IASC, and comments on the book's contribution to our understanding of the IASC and its place in global financial governance.  相似文献

With the abolition of the Audit Commission and the Standards Board for England, and the emphasis in the Localism Act 2011 on local ownership in England for standards, research was undertaken into a group of councils to assess their legislative compliance arrangements and the development of organizational ethical cultures. The research argues that the delivery of the former is a work-in-progress and that there is little evidence of the latter.  相似文献

Observations of nineteen hospitals show how organizational ideologies are manifested and sustained by beliefs, stories, languages, and ceremonial acts. The data indicate that harmonious ideologies accompany simple structures, but that discordant ones accompany elaborate structures. Through their effects on people and structures, ideologies guide organizations’responses to external threats.  相似文献

This paper examines the incidence of capital taxation in a model in which the taxation of capital is clearly justifiable and using analytical techniques from the tax reform literature. The taxation of capital has long been a controversial issue, with much of the literature concluding that savings/capital-income should not be taxed. Recently, however, Blackorby and Brett have shown in a model with several desirable features that it can be optimal to tax capital, and they provide a simple yet compelling argument in favor of both savings taxation and capital-income taxation. We use the Blackorby–Brett model (i.e. a model in which the taxation of capital can be justified) to revisit the question of the incidence of capital taxation. We focus on the generational incidence of capital taxation; that is, the incidence on a young generation and an old generation. However, an interpretation in terms of the incidence on "capital" versus "labor" (as is traditional in the tax incidence literature) is also provided.  相似文献

The currency crisis literature has identified two possible types of crisis: fundamentals based crises and self-fulfilling crises. A fundamentals based crisis arises when some state variable, such as foreign exchange reserves, reaches a critical level and triggers the abandonment of the fixed rate. A self-fulfilling crisis is triggered by an autonomous change in the beliefs of speculators. This paper demonstrates how these two types of crises generate different behaviour in the term structure in the period before the crisis. JEL Classification Numbers: E43, F31  相似文献

This study provides insights from accounting practitioners on China's convergence with International Financial Reporting Standards (IFRS). Through a survey of 33 senior financial executives of Chinese listed companies in 2014, the study reports their perceptions on the following issues: first, the degree of convergence between IFRS and Chinese Accounting Standards (CAS); second, the choice between fair value and historical cost accounting, and the usefulness of fair value accounting for Chinese companies’ financial reporting; third, challenges in the process of China's harmonisation with IFRS; and finally, essential capabilities of Chinese accounting professionals in the process of China's harmonisation with IFRS. Multivariate regression was used for further analysis. The survey findings reveal that in general CAS have converged with IFRS, with a few exceptions that reflect the unique Chinese context. Historical cost accounting is the preferred measurement base to fair value accounting. Exercising professional judgement was identified as a challenge for China's full convergence with IFRS. Ownership structure and the expertise of accounting practitioners were found to affect respondents’ judgements on China's convergence with IFRS. This study has policy implications for international accounting standard setters and accounting educators to consider the contextual issues of implementing IFRS in an emerging economy.  相似文献
