The relationship between the number of employees in a firm, their rank, and the level of professionalism among firm members is evaluated in 19 accounting firms, involving 325 accountants engaged in public practice. Professionalism is measured using five individual traits plus a composite. Results indicate that one trait (i.e. a belief that the profession provides a service to society) and the composite were inversely related to firm size. Rank or position in the firm hierarchy demonstrated an even stronger, independent effect on three professionalism traits and the composite, with higher member rank associated with higher levels of professionalism. Issues related to the future study of professionalism among accountants are discussed.  相似文献

Learning during performance of auditing tasks in the field is modeled as a change in the state of an auditor's knowledge base that results from experience during performance of a task. Several hypotheses are proposed and, along with data obtained by means of behavior observation and concurrent verbal protocols, used to interpret the problem-solving behaviors of four first-year auditors who performed an unfamiliar but audit-related task in simulated auditing environments. Significant findings of learning during performance of the experimental task are reported. While the data show that the auditor-subjects continuously encountered new learning situations throughout the task, they are inconclusive regarding learning through improved knowledge content. On the other hand, significant evidence is found that the learning that did occur was manifest by a greater availability of the auditor-subjects' knowledge. The implications of these findings in terms of the nature of audit tasks and the development of more expert-like task behavior are discussed.  相似文献

This paper outlines the conditions under which trade is beneficial for a developing country's growth. A developing country suffers from two disadvantages: low income and a comparative disadvantage in the production of modern manufactured goods—goods which allow a high rate of human capital accumulation through learning by doing. Low income together with Engel's law imply that developing countries consume and produce very few modern goods in autarky and hence grow slowly. With international fragmentation of production, a developing country may find comparative advantage in the production of some stages of modern goods despite an absence of comparative advantage in the production of modern goods under “100% local content.” More resources can then be allocated to the modern goods sector leading to greater learning externalities and hence growth under free trade than in autarky.  相似文献

Two transitions in the evolution of the social contract are considered, the first from the dominance hierarchies of the great apes (used as a proxy for our prehuman ancestors) to the egalitarian political structure of non-sedentary hunter-gatherer bands, and the second, to the reintroduction of hierarchical institutions of governance, primarily a result of living in fixed settlements after the inception of agriculture. The first transition was a product of biological and cultural evolution, which brought about big brains, language, higher consciousness, and a lower rate of time preference that enabled early man to sustain an egalitarian social contract and thereby escape the domination that confronted his prehuman ancestors. The second transition was a product of cultural evolution alone. The high costs of enforcing the hunter-gatherer social contract caused it to break down and be replaced by hierarchy when the domestication of plants and animals gave rise to a sedentary existence and increased populations. However, it is shown that the very biological and cultural adaptations that made hunter-gatherer egalitarianism possible were a necessary foundation for the spontaneous creation of complex culture and the evolution of institutions that would once again eventually make freedom possible and economic prosperity possible.  相似文献

Teaching New Product Development To Employed Adults   总被引:1,自引:0,他引:1  
The purpose of this article is to report the lessons derived from broad practical experience in teaching new product development (NPD) to employed adults. My observations are importantly augmented by diverse comments from nine other service providers who also conduct and participate in similar NPD education. Our combined lessons summarize what works and what to be forewarned about. (“Those who cannot remember the past are condemned to repeat it.”– George Santayana.) We believe that what we have learned from our very different and extensive involvement can help several audiences: (1) others who offer or plan to offer and deliver NPD education – educators, service providers, or practitioners; (2) organizations that may wish to sponsor NPD training in any form; and (3) those who expect to participate as students in NPD seminars or courses. The article has four main sections, all of which are intended to provide pointers and helpful suggestions based on our collective experience. First is a discussion of issues concerning program set‐up and acceptance. Both sponsors and participants have important responsibilities for this, which are explained. Second is a discussion of practical issues specific to NPD education. The varieties of subject matter and support materials, format options, techniques to sustain interest, instructor characteristics, and client confidentiality are covered. Third is a discussion of practical logistic issues that apply to all adult education but with an emphasis on NPD. Advance warning of what can be and has been encountered may help you circumvent many avoidable problems. Fourth is a brief discussion about the future for NPD education. In this we speculate that the emergence of broadband Internet may provide a new modality, the effectiveness of which is still uncertain. An important insight for you to note is that we do not always do the same thing or approach teaching situations in the same way. What has worked for one of us may not have been effective for another or in another situation. In summary, the experiences we record should help you improve the delivery of NPD education or more efficiently benefit from participation in such training. © 2002 Elsevier Science Inc.

Statement of Financial Accounting Standards (SFAS) No. 96, “Accounting for Income Taxes,” issued by the Financial Accounting Standards Board (FASB) in December 1987 changed accounting for income tax recognition and accrual. The original deadline for implementation of SFAS No. 96 was December 15, 1988, and earlier adoption was encouraged. This study examines empirically the stock price impact of four pertinent announcement dates regarding SFAS No. 96 for 19 banks that adopted the statement in late 1987 and early 1988. Our results suggest that these early bank adopters have different characteristics from other banks that cause them to benefit from the changes in accounting for deferred taxes and explain their voluntary adoption of the standard.  相似文献

Food Safety Through Food Irradiation: Should it be Adopted More by the EU? Food Irradiation is a food safety technology that can eliminate disease‐causing germs from foods. Faut il encourager ?irradiation pour améliorer la sécurité des aliments en Europe? ?irradiation des aliments est une technique de sécurité alimentaire, qui permet ?en éliminer les germes pathogènes. De même que la pasteurisation du lait, le traitement par des radiations ionisantes permet de tuer les bactéries susceptibles de causer des infections ?origine alimentaire. Celles‐ci sont toujours présentes, et ont de graves conséquences tant pour la santé que pour ?économie. Aux Etats‐Unis, ?irradiation est une technique autorisée pour beaucoup de produits alimentaires. Dans ce pays, le nombre de restaurants et de supermarchés vendant des produits irradiés a augmenté de façon considérable au cours des trois dernières années. Des expérimentations économiques montrent que les consommateurs américains sont disposés à dépenser pour le b?uf irradié des sommes sensiblement supérieures aux suppléments de coûts associés à?irradiation. En Europe, ?utilisation de ?irradiation comme technique de conservation des aliments, susceptible de s'insérer dans des programmes de sécurité alimentaire rigoureux, est beaucoup plus limitée. Jusqu'ici, laliste des produits dont ?irradiation est autorisée dans ?ensemble de la Communauté Européenne ne contient qu'une seule catégorie de produits alimentaires:les herbes aromatiques, épices, et assaisonnements ?origine végétale. Avec la globalisation des circuits commerciaux et le renforcement, exigé par les agences de régulation, des normes de sécurité du champ à la fourchette, la généralisation de l0'irradiation des produits alimentaires devrait profiter à?ensemble des producteurs et des consommateurs européens. Nahrungsmittelsicherheit durch Bestrahlung von Nahrungsmitteln: Sollte dies in der EU verstärkt angewandt werden? Bei der Bestrahlung von Nahrungsmitteln handelt es sich um ein Verfahren zur Gewährleistung der Nahrungsmittelsicherheit, bei der krankheitsverursachende Keime in den Nahrungsmitteln abgetötet werden. Wie bei der Pasteurisierung von Milch können Bakterien mit Hilfe von ionisierenden Strahlen in Nahrungsmitteln abgetötet werden, die anderenfalls durch Nahrungsmittel übertragbare Erkrankungen hervorrufen würden. Diese Erkrankungen stellen eine permanente Bedrohung dar und Ziehen ernstzunehmende Konsequenzen für Gesundheit und Wirtschaft nach sich. In den USA dürfen verschiedene Nahrungsmittelarten bestrahlt werden. In den vergangenen drei Jahren hat die Anzahl der Supermärkte und Restaurants in den USA, die strahlungsbehandelte Produkte anbieten, enorm zugenommen. Erste ökonomische Versuche in den USA legen es nahe, dass die Bereitschaft der Verbraucher, einen höheren Preis für bestrahltes Rinderhackfleisch zu zahlen, sehr viel höher ist als die mit der Bestrahlung verbundenen zusätzlichen Kosten. Die Anwendung der Bestrahlung von Nahrungsmitteln als Werkzeug zur Gewährleistung der Nahrungsmittelsicherheit, welches die strengenNahrungsmittelsicherheitspro‐gramme ergänzen könnte, ist in Europa eher begrenzt. Bislang handelt es sich bei den Produkten, die für die Bestrahlung innerhalb der gesamten EU zugelassen sind, nur um eine einzige Nahrungsmittelklasse: getrocknete aromatische Kräuter und Gewürze. Durch die zunehmende Nachfrage der Aufsichtsbehörden nach Nahrungsmittelsicherheit ?vom Stall bis zum Teller? und die Globalisierung des Nahrungsmittelhandels könnten die Produzenten und Verbraucher in der EU von einer verstärkten Anwendung der Bestrahlung von Nahrungsmitteln profitieren. Like pasteurization of milk, treating food with ionizing radiation can kill bacteria that would otherwise cause foodborne disease. Foodborne illnesses are ever present and have serious health and economic consequences. In the US, food irradiation is approved for use in various foods. The number of supermarkets and restaurants in the US that offer irradiated products has increased dramatically in the last three years. Preliminary economic experiments in the US suggest that consumer willingness to pay for irradiated ground beef is substantially greater than the additional costs associated with irradiation. The use of food irradiation as a food safety tool that could complement rigorous food safety programmes is rather limited in Europe. So far, the list of products authorized for irradiation within the whole EU contains only a single food category: dried aromatic herbs, spices, and vegetable seasonings. With increasing demand by regulatory authorities on food safety from ‘farm to fork’ and the globalization of food trade, EU producers and consumers may benefit from wider adoption of irradiation of food products.  相似文献

The banking crises of the ‘90s emphasize the need to model the connections between financial environment volatility and the potential losses faced by financial institutions resulting from correlated market and credit risks. Due to the number of variables that must be modeled and the complexity of the relationships an analytical solution is not feasible. We present here a numerical solution based on a simulation model that explicitly links changes in the relevant variables that characterize the financial environment and the distribution of possible future bank capital ratios. This forward looking quantitative risk assessment methodology allows banks and regulators to identify potential risks before they materialize and make appropriate adjustments to bank portfolio credit qualities, sector and region concentrations, and capital ratios on a bank by bank basis. It also has the potential to be extended so as to assess the risks of correlated failures among a group of financial institutions (i.e., systemic risk analyses). This model was applied by the authors to the study of the risk profile of the largest South African Banks in the context of the Financial System Stability Assessment program undertaken by the IMF in 1999. In the current study, we apply the model to various hypothetical banks operating in the South African financial environment and assess the correlated market and credit risks associated with business lending, mortgage lending, asset and liability maturity matches, foreign lending and borrowing, and direct equity, real estate, and gold investments. It is shown to produce simulated financial environments (interest rates, exchange rates, equity indices, real estate price indices, commodity prices, and economic indicators) that match closely the assumed parameters, and generate reasonable credit transition probabilities and security prices. As expected, the credit quality and diversification characteristics of the loan portfolio, asset and liability maturity mismatches, and financial environment volatility, are shown to interact to determine bank risk levels. We find that the credit quality of a bank's loan portfolio is the most important risk factor. We also show the risk reduction benefits of diversifying the loan portfolio across various sectors and regions of the economy and the importance of accounting for volatility shocks that occur periodically in emerging economies. Banks with high credit risk and concentrated portfolios are shown to have a high risk of failure during periods of financial stress. Alternatively, banks with lower credit risk and broadly diversified loan portfolios across business and mortgage lending are unlikely to fail even during very volatile periods. Asset and liability maturity mismatches generally increase bank risk levels. However, because credit losses are positively correlated with interest rate increases, banks with high credit risk may reduce overall risk levels by holding liabilities with longer maturities than their assets. Risk assessment methodologies which measure market and credit risk separately do not capture these various interactions and thus misestimate overall risk levels.  相似文献
