We combine natural science modelling and valuation techniques to present economic analyses of a variety of land use change scenarios generated for the UK National Ecosystem Assessment. Specifically, the agricultural, greenhouse gas, recreational and urban greenspace impacts of the envisioned land use changes are valued. Particular attention is given to the incorporation of spatial variation in the natural environment and to addressing issues such as biodiversity impacts where reliable values are not available. Results show that the incorporation of ecosystem services and their values within analyses can substantially change decisions.  相似文献

Students today see little relevance in learning double-entry bookkeeping and find it difficult to learn how to prepare journal entries correctly. In particular, they struggle with the first stage of the double-entry process: identifying which accounts are to be debited and which are to be credited for each transaction. This paper reports on an attempt to overcome this situation by using the first printed instructional text on the subject (Pacioli, 1494) as the principal textbook on a 20-hour component of the introductory financial accounting course in an undergraduate accounting degree program. Instruction followed the pedagogy presented by Pacioli and only minimal additional costs to faculty were incurred.  相似文献

The paper analyses the impact of illiquidity of a stock paying no dividends on the pricing of European options written on that stock. In particular, it is shown how illiquidity generates price bounds on an option on this stock, even in the absence of other imperfections, such as transaction costs and trading constraints, or the assumption of stochastic volatility. Moreover, price bounds are shown to be asymmetric with respect to the option price under perfect liquidity. This fact explains, under some conditions, the appearance of a smile effect when the implied volatility is estimated from the mid-quote.  相似文献

Child care as a policy issue has been forced to the center of the national planning agenda in Ireland with the report of an expert working group on child care. As Ireland has broken into the ranks of wealthy Western economies, Irish women have joined the formal workforce in ever greater numbers, dramatically breaking the traditional ideology of women as childbearers and homemakers. However, women are now carrying the double burden of work that accompanies the lack of any state policy on child care. This article traces this recent history of the feminizing of the Irish workforce, amidst a fast-changing social context for family life, and the multiple problems confronting the expert working group of securing an adequate range of policies for the provision of child care in a country which has one of the lowest rates of formal state provision in the entire European Union.  相似文献

This paper is a case study of the impact of an exogenous improvement of a process technology on the structure of the petroleum industry. The paper examines the role of three-dimensional seismology in bringing about the 1990s oil industry consolidation. This proposition is examined in the context of evolutionary economics and in a non-cooperative game theory, concluding with a reference to Steindl's theory of industry dynamics. The significance of this contribution lies chiefly in highlighting the fact that exogenous technological change can, under appropriate conditions, play a significant role in industry dynamics. This reference to the exogenous change in technology is a departure from the traditional consideration of endogenity of industry structure in relation to technological development and, therefore, a novelty. Secondly, the documentation of 3D seismology as a significant process technology of the petroleum industry is significant.  相似文献

This study examines the influence of individual needs and task characteristics on a multifaceted definition of perceived empowerment using an interactional perspective. Respondents were Hong Kong Chinese employees and most of them lower-level or nonmanagerial level workers in business organizations. We used regression analyses to test a number of hypotheses informed by social psychology theories. The significant findings indicate that perceived empowerment is predicted by individual characteristics (need for achievement, need for power), task situations (receipt of task feedback, competency-based reward system, participation in goal setting) and their interactions. Limitations of the study and implications for future research are discussed.  相似文献
