随着经济增长点的多元化以及产业结构的日趋合理,我国企业发展在实现产出增长的同时也带来了严重的环境问题。以企业融资结构与企业环境依存度为切入点,运用Brander和Lewis的寡头垄断博弈分析框架,可以揭示经济增长的区域差异、融资偏好、污染税制度以及企业最优污染治理水平等变量之间的相互关系。通过对不同污染收费制度下的企业行为的比较分析,可以证明在不同的收费制度下,企业自利行为所导致的企业融资偏好以及对环境的污染程度会有所不同。 相似文献

品牌延伸是新产品入市的重要手段。文章从信息储存和使用的角度对品牌认知结构和情景依赖水平如何影响消费者的品牌延伸评价进行了研究,并探讨了不同沟通方式(关系型和阐释型)对不同情景依赖水平消费者品牌延伸评价的影响。研究发现:情景独立的消费者,相对于情景依赖的消费者会有更积极的品牌延伸评价和更好的品牌延伸匹配度感知;关系型沟通能使情景独立者产生更积极的品牌延伸评价和更好的品牌延伸匹配度感知;阐释型沟通能使情景依赖者产生更积极的品牌延伸评价和更好的品牌延伸匹配度感知。 相似文献

Banks occasionally employ frontier efficiency analyses to objectively identify best practices within their organizations. Amongst such methods, Data Envelopment Analysis (DEA) was found to be one of the leading approaches. DEA has been successfully applied in many bank branch performance evaluations using traditional intermediation, profitability and production approaches. However, there has been little focus on assessing the growth potential of individual branches.This research presents five models that examine three perspectives of branch growth. Each model was applied to the branch network of one of Canada׳s top five banks to gauge the growth potential of individual branches and to provide tailored improvement recommendations. Using various analysis methodologies, the results of each model were examined and their functionality assessed. 相似文献

This study develops an applicable profit-oriented productivity indicator when producers pursue profit maximization and can recognize input and output prices. We define the indicator, inspired by the Luenberger indicator and the Nerlovian efficiency measurement, in terms of both quantity distance functions and profit. Hence, the study׳s first stage decomposes the profit-oriented productivity change into two terms: profit efficiency change and profit technology change. Second, we decompose profit efficiency change into the changes in technical efficiency and allocative efficiency. Finally, profit technology change is separated into two components for capturing the shifts of technology and relative output/input prices. These decompositions provide a more complete picture of the sources of productivity change. We illustrate them with a sample of Taiwanese banks and compute the results using the models of directional distance functions. 相似文献

As environment constraints on economic growth are strengthening, Carbon Emissions Abatement (CEA) allocation becomes a significant issue that draws academia׳s attention. In the literature, the Data Envelopment Analysis (DEA) technique has been applied to obtain CEA allocation with centralized models. Nevertheless, a centralized allocation plan suffers from an implementation difficulty in persuading decision-making units (DMUs) into an agreement. In this paper, we propose a new two-step method to mitigate this side effect. In the first step, we provide improved DEA-based centralized allocation models under the assumptions of constant returns-to-scale (CRS) and variable returns-to-scale (VRS) respectively and in the second step, two compensation schemes are developed for centralized allocation plans. An empirical application to the countries in Organization for Economic Co-operation and Development (OECD) is presented to elaborate the main idea. 相似文献

Most models for incomplete data are formulated within the selection model framework. Pattern-mixture models are increasingly seen as a viable alternative, both from an interpretational as well as from a computational point of view (Little 1993, Hogan and Laird 1997, Ekholm and Skinner 1998). Whereas most applications are either for continuous normally distributed data or for simplified categorical settings such as contingency tables, we show how a multivariate odds ratio model (Molenberghs and Lesaffre 1994, 1998) can be used to fit pattern-mixture models to repeated binary outcomes with continuous covariates. Apart from point estimation, useful methods for interval estimation are presented and data from a clinical study are analyzed to illustrate the methods. 相似文献

Revisions of the early GNP estimates may contain elements of measurement errors as well as forecast errors. These types of error behave differently but need to satisfy a common set of criteria for well-behavedness. This article tests these criteria for U.S. GNP revisions. The tests are similar to tests of rationality and are based on the generalized method of moments estimator. The flash, 15-day, and 45-day estimates are found to be ill behaved, but the 75-day estimate satisfies the criteria for well-behavedness. 相似文献
