Encouraging enterprise in deprived places is an important objective of the UK government policy. Evidence on the perceptions of entrepreneurs suggests that access to finance may be harder for firms in deprived areas, who may have fewer contacts, less collateral or worse access to mainstream banks. Yet there is little empirical evidence on whether this is actually the case. This paper investigates whether firms in deprived areas are more likely to find it hard to access finance than other firms, using a sample of around 3500 UK small and medium sized enterprises (SMEs). We find that firms in deprived areas are more likely to perceive access to finance is a problem. However, controlling for SME characteristics, firm growth, credit scores and selection effects, we find no evidence that they actually do find it harder to obtain. The results suggest that geographical disparities in access to finance are unimportant for the average firm.  相似文献

Using a unique primary dataset for the UK, we estimate the effect of individual teachers on student outcomes, and the variability in teacher quality. This links 7,305 pupils to the individual teachers who taught them, in each of their compulsory subjects in the high‐stakes exams at age 16. We use point‐in‐time fixed effects and prior attainment to control for pupil heterogeneity. We find considerable variability in teacher effectiveness, a little higher than the estimates found in the few US studies. We also corroborate recent findings that observed teachers’ characteristics explain very little of the differences in estimated teacher effectiveness.  相似文献

Abstract

There are a number of key characteristics of Ukrainian agriculture which are central to the discussion of the reform process. These include the predominance of state ownership and control, lack of commercial management skills, uneven commitment to reform in a decentralized system of responsibility, monopoly, a low level of technology and limited access to resources that facilitate efficient operation of the market. Necessary restructuring will involve three categories of measures including the establishment of a competitive environment, augmenting enterprise response, and macroeconomic stabilization. At present reform has proceeded extremely slowly and speeding the process appears to require Western aid, both financial and technical, to provide a demonstration of the benefits of reform in order to stimulate its more rapid uptake.  相似文献

The paper examines the impact of management training and development on the organisation and performance of small and medium-sized enterprises (SMEs), via a variety of quantitative and qualitative research techniques and including both crosssectional and longitudinal approaches to analysis. The paper demonstrates the value of management training and development in SMEs and demonstrates a series of one-off and longer lasting effects on their organization and performance. The paper also highlights the conditions under which management development projects are likely to be more successful. Finally, the paper extends the schema developed by Arthur and Hendry (1990) and Hendry et al. (1991), indicating the factors influencing training within businesses, and shows the indirect and complex links between management training and firm performance.  相似文献

Is the Short Rate Drift Actually Nonlinear?   总被引:7,自引:0,他引:7  
Aït-Sahalia (1996) and Stanton (1997) use nonparametric estimators applied to short-term interest rate data to conclude that the drift function contains important nonlinearities. We study the finite-sample properties of their estimators by applying them to simulated sample paths of a square-root diffusion. Although the drift function is linear, both estimators suggest nonlinearities of the type and magnitude reported in Aït-Sahalia (1996) and Stanton (1997). Combined with the results of a weighted least squares estimator, this evidence implies that nonlinearity of the short rate drift is not a robust stylized fact.  相似文献

Sustainability assessment methods are primarily aimed at global, national or state scales. However, modelling sustainability at finer spatial scales, such as the region, is essential for understanding and achieving sustainability. Regions are emerging as an essential focus for sustainability researchers, natural resource managers and strategic planners working to develop and implement sustainability goals. This paper evaluates the effectiveness of current sustainability assessment methods - ecological footprint, wellbeing assessment, ecosystem health assessment, quality of life and natural resource availability - at the regional scale. Each of these assessment methods are tested using South East Queensland (SEQ) as a case study. It was selected because of its ecological and demographic diversity, its combination of coastal and land management issues, and its urban metropolitan and rural farm and non-farm communities. The applicability of each of these methods to regional assessment was examined using an evaluation criteria matrix, which describes the attributes of an effective method and the characteristics that make these methods useful for regional management and building community capacity to progress sustainability. We found that the methods tested failed to effectively measure progress toward sustainability at the regional scale, demonstrating the need for a new method for assessing regional sustainability.  相似文献
