Japanese stock returns are even more closely related to their book-to-market ratios than are their U.S. counterparts, and thus provide a good setting for testing whether the return premia associated with these characteristics arise because the characteristics are proxies for covariance with priced factors. Our tests, which replicate the Daniel and Titman (1997) tests on a Japanese sample, reject the Fama and French (1993) three-factor model, but fail to reject the characteristic model.  相似文献

Canada's wheat grading system is largely based on visual criteria and it is based on relatively high quality standards. A strict varieties licensing system exists to maintain the integrity of the grade standards. One of the consequences of the licensing system is that higher yielding, lower or different quality wheats have not been grown in Canada until recently. The basic objective of this paper is to examine some of the consequences of the regulatory strategy of limiting wheat production to the traditional high quality wheats. This question is analyzed in the context of important changes in the international grain markets. Using a partial equilibrium trade model this paper estimates that if higher yielding wheats were permitted to be grown, annual producer gains would be 5 to 17 percent of current net farm income.
Le classement des blés au Canada est basé sur des critères visuels qui sont de hautes qualités. Le système actuel d'homologation des variétés est tel que l'intégrité de ce système est maintenue. En conséquent, ce système n'a pas encouragé la cultivation des blés de hauts rendements ou des varietés différentes que tout récemment. L'objectif principal de cette étude est d'examiner quelques unes des conséquences de la stratégic de la réglementation visant à limiter la production du blé aux variétés de hautes qualités. Cette question est adressée dans le contexte des changements importants qui ont eu lieu dans le marché international des grains. A l'aide d'un modèle d'équilibre partiel des échanges, la présente étude démontre gu'en permettant la production des blés de hauts rendements, le gain annuel aux producteurs serait de 5 à 17 pourcent du revenue agricole net.  相似文献

The extra vulnerability of industrializing countries to environmental problems and industrial accidents cannot be understood or solved by a ‘normal’ scientific analysis. Aspects of the social and institutional context must be included, through analyses based on post-normal science. The standard two-dimensional classification of PNS is modified to have axes ‘social ‘and institutional vulnerabilities’ and ‘complexity of technological hazards’. The analysis is mainly applied to the case of the relatively rare accidents with catastrophic potential. In these, the deaths per accident in India, Mexico and Brazil are much greater than in the industrialized countries. This discrepancy arises partly from location of such plants near residential communities for marginalized workers and their families. Other socio-political factors are relevant, as the role of these countries in the global production system, the enforcement of safety and planning laws, quality of housing, and lifestyle of residents. Reducing the vulnerability of industrializing countries will therefore require major social policies and a comprehension of the limits of the normal scientific and economic approaches to such problems.  相似文献

Australia has introduced legislation that is aimed at preventing a person from entering into agreements or conducting transactions with the intention of defeating the recovery of employee entitlements. It is essentially aimed at directors and their behaviour in the pre‐appointment period. This paper discusses the history leading up to such a legislative move and the likely benign impact now that the Corporations Act in Australia prohibits such behaviour. Further, the paper argues that mooted changes to the legislation giving employees a ‘maximum priority’ ahead of secured creditors is unnecessary. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

We evaluate the appropriateness of regulation within the Canadian cable television industry by applying both parametric and non-parametric approachesto measure scale efficiency. Although we begin with a sample offering adequatedegrees of freedom for parametric estimation, important policy issues lead us toconsider further estimation over sub-samples. Since some of these sub-samplesare small enough that parametric models cannot guarantee reliable estimates, weobtain production characteristics non-parametrically through data envelopmentanalysis. The nonparametric results for scale efficiency support the parametricresults. We find evidence against a natural monopoly argument that might havejustified continuation of the mandated monopolization of Canadian cable televisionservice. By the end of the sample period, there were no longer substantial economiesof scale in most relevant markets.  相似文献

In applications of expected utility analysis, researchers are confronted with a choice among several utility functional forms. Subjective utility values and probability distributions for price and yield were elicited from Sri Lankan producers of minor export crops. Exponential quadratic and cubic utility functions were estimated. The choice of functional form was found to affect both the classification of risk attitudes and the prediction of harvesting strategy. The exponential function was the best predictor of harvesting strategy because it was the best predictor of mature harvesting. All three functions were equally poor predictors of premature harvesting.  相似文献

One can determine the nature of something by asking what it is for. For example one understands what a chair is when one understands it is for sitting on. This involves understanding its purpose. One type of corporation is the for-profit-corporation. This seems to indicate that this type of corporation, the business corporation, has as its purpose to make a profit. Is that as obvious as it first appears? The favorite way for philosophers to arrive at the "purpose" of anything is to ask the question "Why?" But there are at least two answers to the question "Why"? when addressed to a social practice such as business. One might be asking for a psychological account (explanation) of "Why" a person does business, and this is primarily answered by discovering the motives behind business activity; or one might be asking for a justificatory reason (justification) for the practice – what purpose legitimates business as a human activity. These two answers are often conflated and thus the purpose of business is often considered to be answered by giving the psychological account of the self-interested profit-making motive. This paper will attempt to highlight the importance of making the distinction between motive and purpose clearly, show what confusions arise when the distinction is ignored, and hint at some of the structural philosophical reasons why the distinction got blurred in the first place.  相似文献

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
