Existing literature suggests that the principle of consolidated accounting gained widespread acceptance in Britain during the 1930s. The study reveals that there was little use of consolidated accounting in practice prior to 1945. The prolonged divergence between practice and opinion as to best practice is discussed with reference to both the divorce of ownership from control and the changing perceptions of the nature of shareholders. Finally the widespread adoption of consolidated accounting prior to the Companies Act 1948 is discussed with reference to the impending legislation to enforce group accounting, changing perceptions of the social obligations associated with corporate accounting and several specific events in the corporate environment that may have created incentives to provide consolidated accounts.  相似文献

More diverse, perennial cropping systems often have better natural mechanisms for keeping pests at bay. But while scientists emphasise the broad benefits of conservation in terms of effective ecosystem functioning, farmers are more interested in biodiversity for the provision of food or of services such as shade or windbreaks. Because of their limited knowledge of the role of biodiversity in plant protection, farmers sometimes unconsciously disturb natural regulatory mechanisms. Some citrus farmers in Vietnam introduced sapodilla as an intercrop to diversify their source of income, and because this fruit tree requires little care. However, this apparently worthwhile attempt to combine two valuable crops has misfired. The ecological conditions that traditionally sustained natural pest control in citrus have been disturbed, thus trapping farmers in the pesticide treadmill. The weaver ant Oecophylla smaragdina stopped protecting citrus from stinkbugs and leaf-feeding caterpillars after facing competition from the black ant Dolichoderus thoracicus, which favours sapodilla trees as a nesting habitat. To avoid similar scenarios in the future, methods for linking scientific research on ecosystem functions with farmers' own knowledge, experience and priorities are presented. Examples are given of ways in which farmers in perennial cropping systems learn, and how scientists can facilitate this learning process.  相似文献

This article examines some of the causes and consequences of the recent merger boom and slump in the estate agency market. A case study of the market changes in Plymouth between 1987 and 1992 is presented and contrasted with a recent Tyneside study. It is shown that whilst the merger boom changed the structure of ownership in Plymouth it did not signijicantly affect overall mar- ket concentration as national chains concentrated their take-over strategy on local chains. However, national chains have in- creased their dominance during the recent slump as the result of the exit of many independents from the market.  相似文献

Assuming a symmetric relation between returns and innovations in implied market volatility, Ang, A., Hodrick, R., Xing, Y., and Zhang, X. (2006) find that sensitivities to changes in implied market volatility have a cross‐sectional effect on firm returns. Dennis, P., Mayhew, S., and Stivers, C. (2006), however, find an asymmetric relation between firm‐level returns and implied market volatility innovations. We incorporate this asymmetry into the cross‐sectional relation between sensitivity to volatility innovations and returns. Using both portfolio sorting and firm‐level regressions, we find that sensitivity to VIX innovations is negatively related to returns when volatility is rising, but is unrelated when it is falling. The negative relation is robust to controls for other variables, suggesting only the increase in implied market volatility is a priced risk factor. © 2010 Wiley Periodicals, Inc.

The British credit union movement has grown rapidly over the past decade, albeit from a low base relative to other nations. That growth has been led by a natlonal credlt union pollcy network. Thls article provides a detailed appraisal of the structure of that network, the motivations of its members and the relations between them.

This study highlights the existence of contradictions in the ‘policy space’ occupied by this network that have obscured the public interest In credit union development to date. These contradictions need to be resolved if the performance of the system as a whole is to be improved and public policy goals are to be met Increasing visibtlity ensuing from repeated endorsement of credit unions by the Labour government is bringing added pressures to bear on that network. New actors may be expected to enter the credit union polltlcal market as a result The irnpacts of entry, both positive and negative, are evaluated in terms of the coheslon and effectiveness of ihe credit union policy network.  相似文献

Utilitarian foundations for limited government are shaky insofar as they assume rational and consistent individuals. Recently economists’ assumption of rational actors has come under sustained attack. Behavioural economics has suggested that people are plagued by irrational biases and inconsistencies. These developments have led to a post‐utilitarianism which is held to justify paternalistic interventions by the state via ‘sin taxes’, direct bans or new obligations. Individual responsibility is seriously undermined, as is faith in markets. Supporters of individual freedom need to move away from utilitarian reasoning, reassert core values of autonomy and responsibility, and define strict limits on the scope of government intervention.  相似文献

Two papers of Pindyck, 2000, Pindyck, 2002 that modeled the control of stock pollutants as optimal stopping problems contained closed form solutions that are incorrect. This paper discusses a subtle error in the derivation and demonstrates how solutions to these and related problems can be obtained numerically. The numerical solutions are contrasted with the ones contained in Pindyck's original papers.  相似文献
