This paper explores the methodology of sectoral productivity growth measurement within the framework of input-output analysis. A method which ensures that sectoral productivity growth rates are consistent with productivity growth rates for the economy as a whole (as well as allowing for external trade) is suggested. New estimates are presented on total factor productivity in UK agriculture using a Tornqvist index procedure. In addition, new estimates of agricultural labour productivity growth are presented, taking account not only of labour employed in agriculture but also of labour employed in ancillary industries on the supply side. The empirical results confirm that part of the labour previously employed on farms has shifted “upstream” to industries providing agriculture with fertilises, machinery and other inputs. 相似文献

The Stability Pact ‐ intended to make EMU governments run prudent budgets ‐ is losing its credibility. This article asks the question: what will happen if national debts start to rise again and some governments then have difficulty borrowing? It suggests that there will be calls for bailout, that the EU's political structures will not cope well with the resulting arguments over which countries will pay, and that the eventual and painful result will be a return to the principle that currencies and political areas coincide. 相似文献

In this paper, using a generalised valuation framework inspired by Ohlson, we show that corporate social performance (CSP) is value relevant and that, in particular, it appears to be associated with a higher coefficient on earnings. This could be attributable to either a lower cost of equity for these firms, or greater earnings persistence. We show that, once industry membership is controlled for, any cost of capital effect is minimal. Regression tests based on realised earnings confirm that the valuation effect is attributable mainly to greater earnings persistence in firms with higher levels of CSP. These outcomes are consistent with higher CSP conferring a competitive advantage on firms. 相似文献

This study examines the risk factors in Australian bond returns. The study quantifies bond liquidity and estimates a liquidity risk factor in the Australian setting. We develop a three‐factor asset pricing framework that uses term, default and liquidity risk factors to explain the variation of Australian bond returns. Our findings corroborate the US evidence on the pervasiveness of these risk factors faced by bond investors. The three‐factor model developed in this study has practical applications when calculating the cost of debt, evaluating the performance of an active bond fund manager and hedging underlying risk in a bond portfolio. 相似文献

Small and medium‐sized enterprises (SMEs) are considered increasingly important for economic growth (Wilson, 1995) and effective management of them is regarded as essential for their survival and success (Jennings and Beaver, 1995). This study adopted a multi‐stakeholder perspective in order to explore the promotion, via Training and Enterprise Councils (TECs); provision and (potential for) purchase of competence‐based management training and development (MTD) in the SME sector in the United Kingdom. Survey data from (551) and interviews with (12) SMEs; plus interviews (6) with TECs and interviews (29) with providers of MTD are reported. ‘Product’ deficiencies in competence‐based MTD are identified and recommendations for promotion made. 相似文献

Historically, work on multiple roots for the internal rate of return (PW = 0) equation focuses on tests for the root's uniqueness and interpreting the meaningfulness of computed roots. Instead, this article starts with problems that consist of P, A, and F cash flows. Then for all possible values of these cash flows, this article develops the boundary conditions for no, single, and multiple real roots of either positive or negative sign. The results of characterizing these roots are applied to two examples as a foundation for conclusions about those multiple root problems and hypotheses about other problems with multiple roots. The first example is an important class of resource development projects that may require significant expenditures for environmental remediation at the conclusion of operation. The second example of buying versus leasing a home is often used to demonstrate the value of economic analysis to students. 相似文献

Abstract: We examine performance, and persistence in the performance, of UK 'ethical' or SRI funds and find that performance appears to be time-varying, showing that conclusions on performance itself are influenced by whether a static or time varying model is employed. Given evidence that many UK funds which claim to be international in nature may exhibit home bias in their portfolio allocations, we also propose a new measure for performance of international funds that allows for this and show that such recognition has important implications for the conclusions drawn with respect to these funds. We find evidence that supports persistence in performance, particularly at longer time horizons. There is some evidence that for domestic funds, past 'winning' SRI funds outperform 'losing' SRI funds to a greater extent than their control portfolio counterparts. 相似文献

Estimation of technical inefficiency effects using panel data and doubly heteroscedastic stochastic production frontiers 总被引:3,自引:0,他引:3
In previous studies, measures of technical inefficiency effects derived from stochastic production frontiers have been estimated
from residuals which are sensitive to specification errors. This study corrects for this inaccuracy by extending the doubly
heteroscedastic stochastic cost frontier suggested by Hadri (1999) to the model for technical inefficiency effects. This model
is a stochastic frontier production function for panel data as proposed by Battese and Coelli (1995). The study uses, for
illustration of the techniques, data on 101 mainly cereal farms in England. We find that the correction for heteroscedasticity
is supported by the data. Both point estimates and confidence intervals for technical efficiencies are provided. The confidence
intervals are constructed by extending the “Battese-Coelli” method reported by Horrace and Schmidt (1996) by allowing the
technical inefficiency to be time varying and the disturbance terms to be heteroscedastic. The confidence intervals reveal
the precision of technical efficiency estimates and show the deficiencies of making inferences based exclusively on point
estimates.
