Franchising has attracted the attention of retailing and entrepreneurship scholars in the past three decades, but evidence pertaining to how franchising affects financial performance is mixed and inconclusive. Thus, the question remains as to whether franchising firms exhibit better financial performance than non-franchising firms in the same industry. In order to find an answer to this question, our study compares the risk-adjusted financial performance of franchising versus non-franchising restaurant firms over the 1995–2008 interval, using five different performance measures: the Sharpe Ratio, the Treynor Ratio, the Jensen Index, the Sortino Ratio, and the Upside Potential Ratio. For each measure, the results revealed that franchising restaurant firms outperformed their non-franchising counterparts. Thus, we provide very robust evidence that franchising is superior on average in the restaurant industry, which can help explain the increasing popularity of franchising as a business form. 相似文献

Input price variability is an important source of risk for corporations that process raw commodities. Models of optimal input hedging are developed in this paper based on the maximization of managerial expected utility. The relationship between hedging strategies and output decisions is examined to assess the impact of the ability to set output prices on futures market participation. As a firm's ability to set output prices diminishes in the short run, input futures positions increase although the optimal hedge ratio may either increase or decrease. For a perfectly competitive firm, however, shifts in output price caused by input price changes provide a natural cash market hedge of input price risk and reduce the firm's optimal input futures position. 相似文献

In this article, we advocate more extensive use of the benefit function in specifying price-dependent or inverse demand models. We demonstrate how duality theory may be used to establish the interrelationships between the Marshallian (or Hicksian) inverse demands and Luenberger's adjusted price functions, allowing estimable inverse demands to be derived directly from a benefit function. We estimate two systems of inverse demands for Japanese quarterly fish consumption. Results indicate that the procedures and methods employed here appear promising, and may prove beneficial for quantity and welfare analysis when modeling systems of inverse demand functions. 相似文献

Bob Quinn spent 20 years propagating an ancient Egyptian wheat variety that is generally known as Khorasan wheat. Bob trademarked his wheat variety using the brand name "Kamut® ." Kamut® brand wheat contains some nutritional, health, and taste advantages over modern wheat varieties, but lacks some of modern wheat's agronomic advantages. Kamut® brand wheat is organically produced, and is used to make cereals, breads, cookies, snacks, pancakes, bread mixes, bulgur, pasta, and baked goods. Whole wheat products produced from Kamut® brand wheat are less bitter than those produced from modern wheat varieties. Europe represents approximately two-thirds of the market for this product. 相似文献

In one way or another, all environmental and natural resource problems associated with overexploitation or under provision of public goods, arise from incompletely defined and enforced property rights. As a result private decision makers do not consider or internalize social benefits and costs in their production or investment actions. The gap between private and social net returns results in externalities – harmful effects on third parties: overfishing, excessive air pollution, unwarranted extraction or diversion of ground or surface water, extreme depletion of oil and gas reservoirs. These situations are all examples of the 'The Tragedy of the Commons'. In this paper, I consider options for mitigating the losses of open access: common or group property regimes, government tax and regulation policy, more formal private property rights. I briefly summarize the problems and advantages of each option and describe why there has been move toward rights-based instruments in recent years: ITQ (individual transferable quotas), tradable emission permits, and private water rights. Introductions to the papers in the special issue follow. 相似文献

We evaluate an agricultural extension program aimed at increasing on‐farm biodiversity in Alberta. Using reports prepared for program participants by the extension agency, customized surveys were used to collect data on whether recommended practices were adopted. Data were also collected from producers who were willing but unable to participate in the program due to its unexpected cancellation. A count model compared the number of practices adopted by participants and nonparticipants to evaluate the program's efficacy, and a probit model using participants’ adoption data were used to understand factors affecting adoption. Simple, low‐cost, and easily trialed practices were adopted at high rates, though some higher cost practices associated with observable benefits were also adopted at moderate or high rates. Farm‐specific characteristics, such as size, tenure, or group membership were also significantly linked to the likelihood of adoption. Results suggest that the extension program was successful in encouraging adoption of environmentally beneficial practices with caveats; project completion and quality were not verified, and decreasing marginal returns to extension efforts may have been realized within the small participant pool. Nous évaluons un programme d'éducation permanente en agriculture visant l'augmentation de la biodiversité fermière en Alberta. Utilisant des rapports préparés par les agences d'éducation pour les participants de programmes, des sondages individualisés ont servi à la collecte de données concernant l'adoption de pratiques recommandées. Des données ont aussi été recueillies auprès de producteurs qui auraient voulu participer mais qui n'ont pas profité du programme suivant son annulation inattendue. Un modèle de comptage a servi à comparer le nombre de pratiques adoptées par les participants et non‐participants pour évaluer l'efficacité du programme, et un modèle probit basé sur les données d'adoption par les participants a servi à comprendre les facteurs ayant un impact sur l'adoption. Les pratiques simples, peu coûteuses et faciles à tester ont été hautement adoptées. Certaines pratiques à coûts plus élevés, associées à des avantages observables, ont aussi vu des taux moyens et élevés d'adoption. Les caractéristiques spécifiques aux exploitations agricoles comme la taille, la longévité et l'adhésion à un groupe se sont aussi trouvées liées de façon significative aux probabilités d'adoption. Les résultats suggèrent que le programme d'éducation permanente a réussi à encourager l'adoption de pratiques bénéfiques pour l'environnement avec quelques bémols: la réalisation des projets et leur qualité n'ont pas fait l'objet de vérification, et la diminution des rendements marginaux en fonction des efforts d'éducation pourrait avoir été réalisée dans le cadre d'un petit bassin de participants. 相似文献

Bullying can precipitate many negative outcomes at work, but previous research does not adequately address how such misbehavior affects employee dispositions and attitudes; how these characteristics impact ethical decision making is also underexplored. Given these research gaps, the purpose of this study is to assess (1) the impact of bullying on Machiavellianism and job satisfaction, and (2) the influences of Machiavellianism and job satisfaction on perceived ethical issue importance, a measure of ethical decision making. Three hundred eighty‐four sales and business employees working for different firms operating in the United States answered a self‐report questionnaire. The findings showed that, after accounting for social desirability bias, workplace bullying was positively associated with Machiavellianism and negatively associated with job satisfaction. Machiavellianism was negatively related to the perceived importance of an ethical issue embedded in a vignette highlighting Machiavellianism and latent bullying behaviors. In addition, job satisfaction was positively related to ethical issue importance. Finally, both Machiavellianism and job satisfaction mediated the relationship between bullying experiences and importance of an ethical issue, as evidenced by their significant indirect effects. HR professionals should minimize bullying and Machiavellianism to reduce the corrosive effect on the ethical environment and enhance work attitudes and ethical decisions. 相似文献
