THE DETERMINANTS OF ILLEGAL DRUG USE

An extensive set of self-reported survey data exists on illegal drug use. The survey data show that drug use is quite frequent among the younger adult population, relatively infrequent among those of high-school age, and rare among middle-aged and older adults. Drug use varies by occupational category in ways that are difficult to rationalize. This study utilizes a model in which an individual's time is allocated among labor, non-drug consumption, leisure, and drug use, where the individual is cognizant of the effect of drug use on his wages. The study analyzes comparative static results and then uses data from the National Longitudinal Survey of Youth to estimate a probit model of the individual decision to use drugs. The findings of the study are that non-economic factors dominate the decision for both harder drugs and drugs more broadly defined. One must consider this finding tentative, however, since usable drug price data were not available.     

MEASURING HEDGE EFFECTIVENESS FOR FAS 133 COMPLIANCE

Financial Accounting Standard (FAS) 133 requires business entities to document their anticipation of hedge effectiveness in order to qualify for hedge accounting treatment of gains and losses from financial derivatives. In the absence of specific guidelines, the accounting industry has espoused the "80–125" rule for determining hedge effectiveness. But the authors observe that meaningful assessment of anticipated hedge effectiveness must consider two distinct aspects of a firm's hedging strategy: (1) the strength of the hedging relationship, which is determined by the choice of the hedging instrument; and (2) the position taken in the hedging instrument relative to the holdings of the hedged item. They take both aspects of hedging into consideration in developing alternative measures of hedge effectiveness and distinguishing between the potential and attained effectiveness of a particular hedge. This approach enables the user to evaluate the relative merits of alternative hedging strategies to support risk management decisions, and also to document a selected hedging strategy's anticipated effectiveness for purposes of compliance with FAS 133. While the authors endorse a fairly broad interpretation of hedge effectiveness, their approach can also be used in the narrower context of an "80–125" rule.     

The Multilevel Approach to Repeated Measures for Complete and Incomplete Data

Repeated measurements often are analyzed by multivariate analysis of variance (MANOVA). An alternative approach is provided by multilevel analysis, also called the hierarchical linear model (HLM), which makes use of random coefficient models. This paper is a tutorial which indicates that the HLM can be specified in many different ways, corresponding to different sets of assumptions about the covariance matrix of the repeated measurements. The possible assumptions range from the very restrictive compound symmetry model to the unrestricted multivariate model. Thus, the HLM can be used to steer a useful middle road between the two traditional methods for analyzing repeated measurements. Another important advantage of the multilevel approach to analyzing repeated measures is the fact that it can be easily used also if the data are incomplete. Thus it provides a way to achieve a fully multivariate analysis of repeated measures with incomplete data.

Auditor conservatism and voluntary disclosure: Evidence from the Year 2000 systems issue

This study further examines the phenomenon of conservative auditor behaviour by considering the level of voluntary disclosure of Year 2000 remediation information in company annual reports. Previous studies have provided evidence of conservative auditor behaviour by examining the link between Big 6 auditor choice and accruals (Francis and Krishnan 1999; Becker et al ., 1998; Defond and Subramanyam 1998). Protecting their reputation capital increases Big 6 auditor incentives to act conservatively to avoid litigation risk. We propose and find that Big 6 auditor clients disclose more Year 2000 remediation information than non–Big 6 auditor clients.     

Food Safety Through Food Irradiation: Should it be Adopted More by the EU?

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.     

Making sense of corporate social responsibility in international business: experiences from Shell

International business organizations are regularly addressed on their corporate social responsibility (CSR). As illustrated in this paper, it is not yet clear exactly what CSR means to organizations and how to deal with it. In this paper, the authors explore how a sensemaking approach helps to understand the business challenges of CSR within an organizational context. The theories of Karl Weick are applied to the experiences of CSR in Royal Dutch Shell. The authors argue that the key to CSR in international business organizations is to engage stakeholders and start a process of joint sensemaking. Three main competencies are crucial in this: the competency to engage stakeholders through listening and understanding; the creation of an organizational language so that CSR makes sense to members of the organization; and recognizing the momentum of taking action.

Research notes and communications management and organizational change: A note on the railroad industry

Hypotheses which relate top-level managers' age, years of company and industry service, and education to strategic change are studied with a sample of 855 managers from 27 railroads. Results generally support hypotheses that younger managers and those with less experience are more likely to alter their strategies with changing environmental conditions.     

Duration and the price behavior of fixed-rate level payment mortgages: An analytical investigation

In this research we use a continuous payment formula for duration to examine the price behavior of a fixed-rate level payment mortgage. In the case where the mortgage is held to maturity, duration increases monotonically as term-to-maturity increases, regardless of changes in the market rate of interest. In the case where the mortgage is prepaid prior to maturity, there exists a unique market interest rate below which duration is a monotonically increasing function of time of prepayment, but above which duration has a global maximum at some time of prepayment prior to the term-to-maturity.
