The professions have focused considerable attention on developing codes of conduct. Despite their efforts there is considerable controversy regarding the propriety of professional codes of ethics. Many provisions of professional codes seem to exacerbate disputes between the profession and the public rather than providing a framework that satisfies the public's desire for moral behavior.After examining three professional codes, we divide the provisions of professional codes into those provisions which urge professionals to avoid moral hazard, maintain professional courtesy and serve the public interest. We note that whereas provisions urging the avoidance of moral hazard are uncontroversial, the public is suspicious of provisions protecting professional courtesy. Public interest provisions are controversial when the public and the profession disagree as to what is in the public interest. Based on these observations, we conclude with recommendations regarding the content of professional codes.Karim Jamal is an Associate Professor in the Department of Accounting at the University of Alberta. His research interests are in modelling judgment processes of individuals in professional firms and financial markets. He is currently involved in research on the auditor-client negotiation process, the role of framing effects in masking fraud as well as the means by which frauds are detected, and tensions in professional codes of conduct especially between confidentiality and public disclosure.Norman E.

We take as a starting point the existence of a joint distribution implied by different dynamic stochastic general equilibrium (DSGE) models, all of which are potentially misspecified. Our objective is to compare “true” joint distributions with ones generated by given DSGEs. This is accomplished via comparison of the empirical joint distributions (or confidence intervals) of historical and simulated time series. The tool draws on recent advances in the theory of the bootstrap, Kolmogorov type testing, and other work on the evaluation of DSGEs, aimed at comparing the second order properties of historical and simulated time series. We begin by fixing a given model as the “benchmark” model, against which all “alternative” models are to be compared. We then test whether at least one of the alternative models provides a more “accurate” approximation to the true cumulative distribution than does the benchmark model, where accuracy is measured in terms of distributional square error. Bootstrap critical values are discussed, and an illustrative example is given, in which it is shown that alternative versions of a standard DSGE model in which calibrated parameters are allowed to vary slightly perform equally well. On the other hand, there are stark differences between models when the shocks driving the models are assigned non-plausible variances and/or distributional assumptions. 相似文献

Nine macroeconomic variables are forecast in a real-time scenario using a variety of flexible specification, fixed specification, linear, and nonlinear econometric models. All models are allowed to evolve through time, and our analysis focuses on model selection and performance. In the context of real-time forecasts, flexible specification models (including linear autoregressive models with exogenous variables and nonlinear artificial neural networks) appear to offer a useful and viable alternative to less flexible fixed specification linear models for a subset of the economic variables which we examine, particularly at forecast horizons greater than 1-step ahead. We speculate that one reason for this result is that the economy is evolving (rather slowly) over time. This feature cannot easily be captured by fixed specification linear models, however, and manifests itself in the form of evolving coefficient estimates. We also provide additional evidence supporting the claim that models which ‘win’ based on one model selection criterion (say a squared error measure) do not necessarily win when an alternative selection criterion is used (say a confusion rate measure), thus highlighting the importance of the particular cost function which is used by forecasters and ‘end-users’ to evaluate their models. A wide variety of different model selection criteria and statistical tests are used to illustrate our findings. 相似文献

In 1988 the Journal of Business Ethics published a paper by David Mathison entitled Business Ethics Cases and Decision Models: A Call for Relevancy in the Classroom. Mathison argued that the present methods of teaching business ethics may be inappropriate for MBA students. He believes that faculty are teaching at one decision-making level and that students are and will be functioning on another (lower) level. The purpose of this paper is to respond to Mathison's arguments and offer support for the present methods and materials used to teach Master level ethics classes. The support includes suggested class discussion ideas and assignments.Victoria K. Strong is a graduate student at Bentley College.

Abstract. Cost synergies are an explicitly recognized justification for a two‐firm merger, and empirical techniques are now widely used to assess the impact of cost‐reducing mergers on prices and welfare in the post‐merger market. We show that if the merger occurs in a vertically product differentiated market, then the merger will lead to a reduction in product offerings that limits the usefulness of pre‐merger empirical estimates. Indeed, we further show that in such markets, two‐firm mergers will typically lead to higher prices regardless of the merger's cost savings. JEL classification: L10, L41 相似文献

This article addresses the continued need for the behavior change process that must be managed long after materiel requirements planning (MRP II) implementation. Mason & Hanger, Pantex Plant is the final assembly and dismantlement facility for all United States nuclear weapons. On October 1, 1990, Mason & Hanger implemented a full production cutover to MRP II. One year later, following class A certification, the MRP II implementation team is still actively managing the change process through education and training programs and overall continuous improvement initiatives. Actual behavior change problems are identified together with the proven solutions implemented in a government-owned, contractor-operated facility environment. Performance measurements ranging from senior management planning to shop floor accomplishments and cost variance reports are shown as normal management tools used to identify target improvement areas. 相似文献

Strong JW 《Hospital materiel management quarterly》1995,16(3):5-9
By looking beyond alliances and groups as simply a "vendor" of group purchasing contracts, a hospital can realize significant additional value beyond acquisition price. Doing so takes an attitude conducive to partnership on both sides. When this occurs, the value delivered from these services can often exceed the savings from the group contracts themselves. 相似文献

The introduction of competition within the National Health Service (NHS), with the purchasers having a degree of choice among providers, has raised a variety of issues for buyer-supplier relationships. Purchasers, especially GP fundholders, have power in relation to their provider in the sense that they may ultimately take their custom elsewhere and by transferring their business, or part of their business, from one trust provider to another. As GP fundholders increase in number, and in confidence, this practice seems likely to grow. Using evidence from commercial markets, this article explains why fundholders might switch provider and the implications this has for hospital trusts. 相似文献
