This paper examines intra‐Big 4 audit fee premiums in the Australian market. During the period examined (2002–2004), there is both Big 4 and intra‐Big 4 market dominance. The three largest firms – the ‘Big 3’ (Ernst & Young, KPMG and PricewaterhouseCoopers) – hold over 80 per cent of audit fees for companies listed on the Australian Securities Exchange. We find the main feature of the Australian audit market over this period is a PwC brand premium, which suggests price competition and thus no collusive pricing. Within the Big 4, audit pricing effects are likely to be a growing area of inquiry in future audit pricing literature. Overall, our study implies that regulatory concerns about a lack of a competition in the audit market during this period are inconsistent with the audit pricing evidence.  相似文献

Many scholars across various academic disciplines are investigating the following questions: What do individuals know or believe about an organization? How does a focal organization (and/or other interested entity) develop, use, and/or change this information? and How do individuals respond to what they know or believe about an organization? Cross-disciplinary research that centers on these questions is desirable and could be enhanced if researchers identify and develop consistent terminology for framing these questions. The authors work toward that end by identifying four central ‘viewpoints’ of an organization and proposing labels to represent each of these viewpoints:identity, intended image, construed image, andreputation.  相似文献

If teachers are not equipped to teach Technology Education subject nationally and internationally, the continent of Africa will continue to bear the brunt of unsavoury results unless radical interventions are implemented to transform the situation. It is against this background that action research methods became a useful site-based support to empower Technology teachers at three sampled schools from Tshwane South Circuit in Gauteng Province of South Africa. The purpose of this study was to share fresh perspectives on how a sample of Technology teachers responded to content-related classroom practices during reflective action research activities that took place during community engagement contact sessions. These teachers, who are under qualified and unqualified to teach this subject, were engaged in circular and spiral action research cycles. The teachers’ engagement brought forth the development of Technology Education Cascading Theory. It was evident that community engagement activities served as a podium to transform teachers’ teaching of Technology Education and enhance learners’ achievement. The study was underpinned by cooperative enquiry theory and engaged participants in reflective practices of developmental action paradigm. Interaction with Technology Education teachers further revealed that most of them need their schools to budget for this Technology subject they are teaching.  相似文献

Whereas economic theory suggests that, all else equal, workers should be willing to accept disamenities such as higher housing costs and longer commutes only if they are compensated with higher wages, little is known about the magnitude of these compensating differentials. In this article, I address this gap in the literature by estimating an empirical model of the relationship between wages, housing prices and commutes that addresses the simultaneous determination of these variables. The results from the empirical models suggest that the wage premia associated with high housing costs and long commutes are substantial. Furthermore, results from baseline models reveal that estimates of these compensating differentials are seriously biased if endogeneity is not addressed.  相似文献

This article explains some practical lessons learned from developing and implementing balanced scorecard programs in businesses having up to 800 employees. To avoid implementation pitfalls, the article provides some recommendations that can have a positive effect on any balanced scorecard initiative. © 2007 Wiley Periodicals, Inc.  相似文献

We study the effect of parameter uncertainty on the long‐run risk for three asset classes: stocks, bills and bonds. Using a Bayesian vector autoregression with an uninformative prior we find that parameter uncertainty raises the annualized long‐run volatilities of all three asset classes proportionally with the same factor relative to volatilities that are conditional on maximum likelihood parameter estimates. As a result, the horizon effect in optimal asset allocations is much weaker compared to models in which only equity returns are subject to parameter uncertainty. Results are sensitive to alternative informative priors, but generally the term structure of risk for stocks and bonds is relatively flat for investment horizons up to 15 years.

With the development of an MCMC algorithm, Bayesian model selection for the p 2 model for directed graphs has become possible. This paper presents an empirical exploration in using approximate Bayes factors for model selection. For a social network of Dutch secondary school pupils from different ethnic backgrounds it is investigated whether pupils report that they receive more emotional support from within their own ethnic group. Approximated Bayes factors seem to work, but considerable margins of error have to be reckoned with.  相似文献

The theoretical model of Gaertner (1974) and Pollak (1976) for the interdependence of preferences in the Linear Expenditure System is estimated for a cross-section of households. The interdependence of consumption of different households has implications for the stochastic structure of the model and for the identifiability of its parameters. Both aspects are dealt with. The empirical results indicate a significant role played by the interdependence of preferences. One of its implications is that predictions of the effects of changes in a household's exogenous variables differ according to whether the exogenous variable only changes for this household or for all households jointly. © 1997 John Wiley & Sons, Ltd.  相似文献

To address agility in public administration, we have developed a knowledge acquisition infrastructure for legal knowledge, based on an implementation‐oriented conceptualization of the legal system. Our objective is to reframe legal knowledge as a knowledge source in a design‐oriented task ontology, building on insights from the CommonKADS methodology for intelligent system design. The main result is to make case law and legal expert knowledge of critical incidents in organizations, two diagnostic knowledge sources underutilized in modern management and engineering, more accessible as a resource for design of agile organizational structures and intelligent systems.
