A Data Envelopment Analysis-Based Methodology Adopting Assurance Region Approach for Measuring Corporate Social Performance

Many research papers calculate corporate social performance (CSP) with the net score method, i.e., by subtracting the number of concerns from the number of strengths. Although widely adopted, this method implies, perhaps mistakenly, that each indicator is of equal importance and that however serious the social misconduct a firm may have engaged in, it can be completely offset by some positive social action. The method also implies that a given firm that has done both a lot of harm and a lot of good will have CSP similar to that of another firm that has done little harm and little good. In this study, however, we question the appropriateness of the net score method in terms of its ability to truly reflect CSP and truly identify the real effects of CSP on various characteristics. We therefore propose a data envelopment analysis-based methodology that adopts the assurance region approach for evaluating CSP, through which various CSP indicators are converted into a single composite measure of CSP. Our findings show that our proposed methodology consistently performs better than the net score method in evaluating CSP.

     

THE CREDIT‐CHANNEL TRANSMISSION MECHANISM AND THE NONLINEAR GROWTH AND WELFARE EFFECTS OF INFLATION AND TAXES

With the credit‐channel effect driven by the central bank's open market operations, this paper's model easily gives rise to the nonlinear inflation‐growth nexus, which is evidenced by a number of cross‐country empirical studies. The threshold level of the inflation rate is found to be lower when tax rates are higher. The presence of the credit‐channel effect also provides the rationale for setting positive (and smaller than 1) tax rates on consumption, labor income, and capital income. The optimal tax rates rise as the inflation target declines. Under a fiscal policy rule where labor and capital income taxes move proportionally to each other, the optimal capital income tax rate could be higher than the optimal labor income tax rate. Under a sufficiently large central bank balance sheet, the credit‐channel effect will be so weak that inflation and all kinds of taxes are growth and welfare repressing. This provides a rationale for central banks that have implemented quantitative easing policies to shrink their balance sheets. (JEL E58, E62, O42)     

Supportive organizational environment,work-life enrichment,trust and turnover intention: A national survey of PRSA membership

Based on an online survey of a national random sample of the PRSA membership (n?=?650), this study is among the first to explore public relations employees’ own turnover intention and propose three contributing factors for employers to keep top talent in PR industry: a family-supportive organizational environment; the positive, enriching impact of professional work upon practitioners’ life; and PR practitioners’ trust toward employers. Theoretical and practical implications are discussed.     

Relation between the skew-rank of an oriented graph and the independence number of its underlying graph

An oriented graph \(G^\sigma \) is a digraph without loops or multiple arcs whose underlying graph is G. Let \(S\left( G^\sigma \right) \) be the skew-adjacency matrix of \(G^\sigma \) and \(\alpha (G)\) be the independence number of G. The rank of \(S(G^\sigma )\) is called the skew-rank of \(G^\sigma \), denoted by \(sr(G^\sigma )\). Wong et al. (Eur J Comb 54:76–86, 2016) studied the relationship between the skew-rank of an oriented graph and the rank of its underlying graph. In this paper, the correlation involving the skew-rank, the independence number, and some other parameters are considered. First we show that \(sr(G^\sigma )+2\alpha (G)\geqslant 2|V_G|-2d(G)\), where \(|V_G|\) is the order of G and d(G) is the dimension of cycle space of G. We also obtain sharp lower bounds for \(sr(G^\sigma )+\alpha (G),\, sr(G^\sigma )-\alpha (G)\), \(sr(G^\sigma )/\alpha (G)\) and characterize all corresponding extremal graphs.     

母国区域制度质量对民营企业海外市场进入模式的影响

  海外市场进入模式是跨国企业实现国际化战略目标的重要战略决策。虽然国内外学者已经意识到制度因素对新兴市场跨国企业海外市场进入模式的影响,但大多集中在对东道国制度环境影响的研究,很少考虑母国区域制度环境的复杂性,且缺乏相应的实证检验。         在此背景下,基于制度理论和社会资本理论,探讨母国区域制度质量对中国民营企业海外市场进入模式的影响机理。以规制差异和文化差异为调节变量,以社会资本为中介变量,构建母国区域制度质量与民营企业海外市场进入模式之间关系的概念模型,并以2015年进行海外市场投资的210家中国民营上市企业为研究对象进行实证研究。         研究结果表明,①母国区域制度质量与民营企业海外市场进入模式呈正相关关系,即所处的母国区域制度质量越好,民营企业更倾向于选择独资的海外市场进入模式;②母国与东道国间的规制差异和文化差异负向调节母国区域制度质量与民营企业海外市场进入模式的正向关系;③社会资本对母国区域制度质量与民营企业海外市场进入模式的关系起部分中介作用,即民营企业获得的社会资本越多,对市场信息等方面的把控能力越强,越倾向于采用独资的海外市场进入模式。         研究结果展现了中国市场分割情景下民营企业海外市场进入模式的独特性,拓展了国际商务领域对新兴国家制度环境的理解和认识,促进了制度理论和社会资本理论在国际商务领域的应用和发展。在管理实践中,民营企业在进行海外市场进入模式决策时,应充分考虑其所在的区域制度环境,同时也要善于构建不同类型的社会资本,以提高企业战略决策的可靠性和有效性。     

“异地高考”政策推进策略——基于国家—地方—个体的视角

异地高考政策实行以来,公众对其后续推进寄予了广泛关注。其未来走向不仅关涉学生异地升学、考试的权利问题,更成为城镇化健康发展、教育公共服务不断完善的重要内容。从政策推进角度,国家政策层面应当加强对异地高考价值转变的引导;地方政策层面应当加强回应型政策力度,形成梯度发展规划;同时拓宽下层公众意见表达渠道,加强政策制定的主体导向。

中国GDP核算误差的特征事实与发生机制——兼论计量模型方法对于GDP数据质量的评估功效

基于GDP数据的历史修订与地区差异情况,依照反事实分析的推理逻辑,考察GDP核算误差的特征事实,探讨其中覆盖误差、操作误差以及估算误差的发生机制与影响模式。结果表明,在各年份现价GDP数据中,由覆盖误差和估算误差造成的综合效应是以系统性的低估为主,其中服务业部门是核算误差的主要来源所在;地区层级GDP核算过程中覆盖误差、估算误差与操作误差的综合效果以持续性的数据高估为主,其中的操作误差效应也会存在于国家层级的GDP核算中。由于缺乏对于GDP核算误差发生机制的必要考虑,计量模型方法在评估GDP数据质量中的功效非常有限。
