The large-scale failures of development banks in the 1970s and 1980s meant that they all but disappeared from the development agenda. However, there are still a large number of development banks worldwide that operate with various degrees of success. Some governments are also looking to re-establish such banks to address the shortage of finance for higher-risk market segments. To avoid a repeat of the earlier failures, government policy needs to be informed by an objective framework for the success of these banks. This article, based on economic theory and informed by case studies, outlines such a framework. It addresses the following six dimensions of these banks: enabling environment, mandate, regulation and supervision, governance and management, financial sustainability and performance assessment. Development banking remains a risky initiative but, managed appropriately, and using this framework, it can help achieve development objectives.  相似文献

To promote auditor independence and audit quality in English NHS Trusts the Audit Commission regulates auditor rotation, fees and the appointment of its own and private sector auditors. NHS sanctioned departures from GAAP, some of which allow the financial breakeven target to be achieved, have been criticised by the Audit Commission as detrimental to financial discipline. In this paper, we investigate the association between abnormal accruals and the achievement of financial breakeven in NHS hospital Trusts over the period 1998–2005. We also investigate the association between abnormal accruals, audit fees and the Trusts audited by public and private sector auditors. We find evidence that abnormal accruals are used to achieve financial breakeven and they differ across different types of auditor. We also identify a negative relationship between abnormal accruals and NHS Trust star ratings. These findings raise questions about the ‘quality’ of NHS audit where compliance with NHS-specific regulations overrides the wider GAAP-based requirement for financial statements to show a true and fair view and they warrant reconsideration of the nature of audit in NHS Trusts.  相似文献

This paper concerns the analysis of farmers' goal trade‐offs using a series of representative dairying and beef/sheep farm models. The models employ an adaptive feedback structure and expectations model to track adjustment processes over a seven‐year planning horizon, 1991/92 to 1997/98. Model solutions, under a conventional profit maximising objective function, and using a weighted goal programming formulation, under a series of empirically specified alternative goal orientations, are examined and compared. The paper identifies significant variation among farm families in terms of ability to attain key goals concerning farm profitability, family consumption, farm investment, growth and cash flow. The results quantify the trade‐off between family consumption and farm investment/growth goals.  相似文献

The viability of irrigated systems in Southern Europe is closely linked to efficient institutional settings and water‐allocation mechanisms. A significant, although not widely used, mechanism for water allocation is an intra‐sectorial water market. The objective of this paper is to evaluate to what extent water markets may contribute to the improvement of the efficiency of water allocation and to the profitability of irrigated agriculture. The related issues of water allocation among farm types and farm specialisation are also addressed. The analysis is based on a basin‐level linear programming model, comparing the situation with and without a market. It includes both fixed and variable transaction costs and estimates their combined effects on market performances. The model is applied in two areas in Southern Italy and Spain, and simulates the behaviour of different farm types, derived from cluster analysis on a sample of farms in each area. The paper confirms that water markets could potentially improve the economic efficiency of water use, in terms of higher profit per hectare, given limited water availability. The potential improvements are associated with a more intense specialisation of farms and are strongly differentiated among farmers, particularly where significant restrictions to water availability occur. This corroborates the expectations of institutional difficulties in implementing water markets. However, the exchanges, and consequently the potential effects of water markets, are heavily affected by the actual level of water availability, as well as the size and the structure (fixed vs. proportional) of transaction costs. The paper calls for a more in‐depth analysis of the connections between market performances and institutional settings, as related to the issue of water‐agriculture policy design and coordination.  相似文献

The Employment Research Unit undertook three surveys on the informal sector during 1985 and 1986, two among Blacks and one among Coloureds. The aim of the surveys was to establish the composition and nature of the sector in the Port Elizabeth/Uitenhage area. It was found that in both these sectors most of the respondents were involved in trading and that very few were involved in manufacturing. Incomes earned by most of the respondents were low. and compared to subsistence level incomes only, It also appeared that the employment creation spin‐off was low. Similar problems inhibited the growth and development of this sector for both Blacks and Coloureds. They were: short‐ and long‐term loans, accommodation, poor infrastructure, and legal restrictions.  相似文献

Since measurement errors have strong effects in all relationships (statistical or otherwise) studied, there is an increasing interest in the data quality, which is the major justification for this research. This paper aims to present a new measurement procedure, the letter scale, which avoids many of the problems connected with the response modalities traditionally used in attitudinal research, especially the ordinal categorical scales. This paper analyzes the error composition of the scores obtained with this new measurement procedure. The validity of the procedure is also analyzed and the observed variance is assessed to determine which part of the observed variance is “valid”, which part is random error (attenuating relationships) and which is correlated error (magnifying relationships). Structural equation models will be used to provide estimates of the measurement quality: (i) Reliability, (ii) Construct validity, method effect and residual variance. In addition, this letter scale is evaluated under another different perspective, Information Theory measures are also used to assess the amount of information transmitted. The relative merits of this new measurement procedure as opposed to other common response modalities will be discussed in both cases.  相似文献

The clothing industry has been saved largely as a result of the introduction of new technology in response to an increasingly competitive market place. But what affect has this restructuring had upon jobs? We explore how women workers have experienced this change and why policy-making should consider job design.  相似文献
