In the present paper a comprehensive assessment of existing mutual fund performance models is presented. Using a survivor‐bias free database of all US mutual funds, we explore the added value of introducing extra variables such as size, book‐to‐market, momentum and a bond index. In addition to that we evaluate the use of introducing time‐variation in betas and alpha. The search for the most suitable model to measure mutual fund performance will be addressed along two lines. First, we are interested in the statistical significance of adding more factors to the single factor model. Second, we focus on the economic importance of more elaborate model specifications. The added value of the present study lies both in the step‐wise process of identifying relevant factors, and the use of a rich US mutual fund database that was recently released by the Center for Research in Security Prices. 相似文献

The purpose of this article is to study the level of “in‐stock” customer service performance being offered in the catalog channel of distribution. The article provides benchmark information for the catalog industry. More importantly, the article serves as one test of the effectiveness of the modern supply chain, where the expectation is for near perfect orders. Customer service levels are studied by using an empirical observation methodology in which catalog retailer's in‐stock performance was measured. Comparisons are made across item type, season, retailer type, and days from catalog receipt. Overall, items were out‐of‐stock during 15.9% of all checkpoints, compared to an 11.8% stock‐out rate in an earlier study of bricks and mortar retailers. 相似文献

Activity-based costing (ABC) offers a way to improve performance evaluation by providing estimates of the cost of satisfying sales terms to which a sales representative may agree, such as number of batches in which an order is produced and number of training hours provided to customer employees. It also provides estimates of the cost of resources that a sales representative may use while engaging in marketing activities, such as making sales calls and attending trade shows. Traditional costing, which assumes that costs only vary at the unit level, does not provide estimates of the costs of many of these terms and activities. 相似文献

Global sourcing strategy and sustainable competitive advantage 总被引:1,自引:0,他引:1

Global sourcing strategy has been one of the most hotly debated management trends in the last 20 years. In its early years, global sourcing was examined mostly from “in-house” development and procurement perspectives; and in the last several years, research focus has shifted to “outsourcing” activities. Along with this shift from internal to external focus on global sourcing, many researchers and business practitioners have applied a core competency argument to justify increased levels of outsourcing activities on a global basis. Although the beneficial aspects of outsourcing are assumed in most cases, no consensus exists in reality as to the effect of outsourcing. Furthermore, the increased instability of the exchange rate environment in the last several years has also led to increased difficulties in managing globally scattered operations that were once fashionable in the 1980s-90s under the rubric of global strategy. In this article, the authors explore potential limitations and negative consequences of outsourcing strategy on a global scale. 相似文献

衍生型环境BSC的构建使环境管理对经济成功贡献之间所暗存的因果关系更明晰化、可视化,为促进企业成功实施环保战略提供了管理工具和方法。在国内外相关文献的理论指导下,探讨了衍生型环境BSC的绩效评价指标体系的构建路径和基本架构。把环保战略转化为因果关系耦合的目标和指标,是构建衍生型环境BSC绩效评价指标体系的重要依据。衍生型环境BSC需要从四个维度——财务、客户、内部流程和学习与成长——挖掘与环境相关的内容。结合石化企业的行业背景和企业资料进行了案例分析,为其构建衍生型环境BSC提供一种思路和框架。 相似文献

中国银行业的市场结构与银行绩效关系研究——基于33家商业银行面板数据的实证检验 总被引:1,自引:1,他引:1
以33家商业银行1997—2004年的数据为研究对象,以赫芬达尔指数作为衡量市场结构指标,本文对中国银行业市场结构与银行绩效关系进行了研究。研究结果表明,市场集中度降低对四大国有商业银行盈利能力没有产生显著性影响,但削弱了其他股份制商业银行和城市商业银行的盈利能力。市场集中度与所有银行净利息边际存在显著的负相关关系,不能跨地域经营的城市商业银行净利息边际显著低于其他商业银行。因此应该适度放开城市商业银行经营的地城限制。并防止过度竞争。 相似文献
