Planning in feasible region by two-stage target-setting DEA methods: An application in green supply chain management of public transportation service providers

To meet green supply chain management’s requirements of a company and its transportation service providers (TSPs), it is essential to set clear, achievable, and realistic targets. This paper proposes two data envelopment analysis (DEA) approaches to find targets for two-stage network structures. The objective of proposed approaches is to plan in feasible region. The feasible region specifies bounds to ensure targets are within current operational capacity of TSPs. Applying the approaches to set targets for 24 TSPs lead to different results. However, proposed models ensure that the TSPs would be efficient in their current capacity.     

Locke的目标设置理论及其对组织绩效的影响研究

Locke提出的目标设置理论,经过不断发展完善,已成为当代重要的激励理论。该理论认为,目标本身就具有激励作用,目标能把人的需要转变为动机,使人们的行为朝着一定的方向努力,并能及时进行调整和修正,从而能实现目标。目标设置包含两个基本维度,分别是目标内容和目标强度。国内外的大量研究也都证明,目标设置对组织承诺、工作满意度等组织绩效指标有显著影响。

Relative Prices in Monetary Union and Floating

The setting is a small open economy with an open sector and a sheltered sector. If the unions that operate in each sector coordinate their wage claims within the sector, the choice of monetary regime—monetary union or floating with an inflation target—affects the relative prices of tradables and non–tradables as well as real wages and employment. EMU membership results in lower prices of tradable goods and lower relative wages in the open sector, while opposite results hold for sheltered sector prices and wages.

An Experimental Investigation of Alternative Going‐Concern Reporting Formats: A Canadian Experience*

This study questions whether the current or proposed Canadian standard of disclosing a going‐concern contingency is viewed as equivalent to the standard adopted in the United States by financial statement users. We examined loan officers' perceptions across three different formats ‐ namely, an integrated note with a clean auditor's report (the current Canadian standard), a stand‐alone note with referencing on the face of the balance sheet and income statement (the proposed and now rescinded standard), and a modified auditor's report with an explanatory paragraph in addition to a stand‐alone going concern note (the standard adopted in the United States and other countries). Bank loan officers were selected as the appropriate financial statement users for this study. The results of the test of the hypothesis suggest that once the going‐concern note is fully disclosed in the notes, the style of presentation within the notes (a stand‐alone note versus an integrated note) does not significantly influence the reactions and perceptions of risk if the auditor's report is unmodified (i.e., if no reference is made to a going‐concern contingency). However, when the auditor's report is modified with an explanatory paragraph detailing the uncertainty and referencing the going‐concern note in the footnotes, the format appeared to convey a stronger signal of financial distress to loan officers. These results appear to differ from prior research, which holds that once the information is released in the financial statements, the format has no additional effect. The finding of this study is that the proposed and withdrawn Canadian standard was not perceived differently by the bankers from the present Canadian standard, but the standard adopted in the United States and most other countries was. This makes a strong argument for moving all the way to that standard as opposed to the “halfway” approach of the now rescinded CICA exposure draft. Thus, the public interest in Canada may not be served by adopting a halfway approach.     

企业销售目标制定方法的改进——层次分析法和模糊综合评价法的结合

本文将模糊综合评价模型和层次分析法综合应用于对企业销售目标和区域（省）目标的制定，并建立了一个综合考虑各影响因素同销售目标关系的数学模型，该模型用于研究影响销售目标制定的主要因素及其相互关系。此外，本文将一些主观判断因素进行了量化，这对企业目标的制定、绩效评价和体现激励的公平性具有一定的指导意义。

The Law of One Price—A Case Study

We use retail transaction prices for a multinational retailer to examine the extent and permanence of violations of the law of one price. For identical products, we find typical deviations of 20–50 percent, with some evidence for convergence over time. Such differences might be due to differences in local costs. If so, relative prices of similar products (round versus square mirrors) should be equal across countries. In fact, relative prices vary significantly across very similar goods within a product group. The finding suggests that differences in local distribution costs, local taxes, and probably tariffs do not explain the price pattern, leaving strategic pricing or other factors resulting in varying markups as alternative explanations.
