关于提升机场工程咨询评审价值的研究

民用机场建设工程,不论是运输机场还是通用机场,都有法定的基本建设程序,以及对应的评审要求。评审基本原则是独立、公正、科学。但如何实现、提升机场工程咨询评审的价值,既是完成评审工作的基本要求,也是体现评审单位业务水平与差异化服务的关键所在。本文基于现民航基建程序规定的项目评审,研究在首先保证评审质量前提下如何提高效率,如何让评审对项目产出效益,以及如何强化评审的增值服务等综合提升评审单位的评审价值。     

Nearly exact sample size calculation for powerful non‐randomized tests for differences between binomial proportions

In the case of two independent samples, it turns out that among the procedures taken in consideration, BOSCHLOO'S technique of raising the nominal level in the standard conditional test as far as admissible performs best in terms of power against almost all alternatives. The computational burden entailed in exact sample size calculation is comparatively modest for both the uniformly most powerful unbiased randomized and the conservative non‐randomized version of the exact Fisher‐type test. Computing these values yields a pair of bounds enclosing the exact sample size required for the Boschloo test, and it seems reasonable to replace the exact value with the middle of the corresponding interval. Comparisons between these mid‐N estimates and the fully exact sample sizes lead to the conclusion that the extra computational effort required for obtaining the latter is mostly dispensable. This holds also true in the case of paired binary data (McNemar setting). In the latter, the level‐corrected score test turns out to be almost as powerful as the randomized uniformly most powerful unbiased test and should be preferred to the McNemar–Boschloo test. The mid‐N rule provides a fairly tight upper bound to the exact sample size for the score test for paired proportions.     

Recontextualising a strategic concept within a globalising company: a case study on Carlsberg's ‘Winning Behaviours’ strategy

A corporate strategy is often formulated on the executive floor at headquarters. However, in order to make it live in an organisation, middle management and employees must be involved and make sense of it. These actors thus contribute to, participate in and enact the strategy in processes where it may take on new meanings and forms. This article investigates how ‘Winning Behaviours’, a strategic concept developed on the initiative of top management at the Carlsberg Group in order to improve global integration in the multinational organisation, was recontextualised. It draws upon interviews and observations as well as documents collected at the company headquarters in Denmark and in its subsidiaries in China and Malaysia. Here, expatriate and local managers tried to give sense to the Winning Behaviours in various ways, and employees brought their own local leadership ideals into play when they tried to make sense of the preferred behaviours and turn them into daily practices. The process of creating a new strategic concept and making it live in other sociocultural contexts was facilitated by headquarters staff in the Human Resources and Communications departments, who thus played an important role as change agents in the ‘glocal’ strategy process.     

企业慈善行为测量及其对员工职场精神力的影响

针对现有企业慈善行为测量单一化、短期化与外部化的局限以及从内部员工视角研究慈善战略价值的欠缺,开展了两个关联研究。在研究一中,采用归纳法开发并检验了一份包含内外部慈善的日常性企业慈善行为量表。结果显示,企业慈善行为具有一阶双因素结构,由外部慈善行为与内部慈善行为因素构成。该量表信效度较好,可用于实证研究。在研究二中,检验了企业慈善行为对员工职场精神力的影响,结果显示内外部慈善均对员工职场精神力有积极作用,其中内部慈善行为作用更强。员工的"与组织价值观一致"相对"团体感"和"工作意义"被企业慈善行为解释的程度最高,表明企业慈善行为受到了员工高度的价值认同。     

信用评级高估与融资的所有制歧视——基于中国公司债的数据

为了分析发债主体所有制性质对公司债发行定价影响的作用机理,从信用评级高估的假设出发,将所有制性质的定价作用区分为直接效应和间接效应,基于贝叶斯法则得出两个推断：评级高估会导致发债主体所有制性质对公司债发行定价的直接效应;高信用等级公司债发行定价会受到发债主体所有制性质的直接影响,低信用等级公司债则不然。通过对2007—2013年沪深两市公开发行的公司债进行实证分析,推断得到了验证。这些分析有利于剖析民营企业融资歧视的形成机制。     

发挥市场机制决定作用化解产能过剩——以江苏为例

本文利用生产函数法,实证测度江苏省产能利用情况,发现江苏省制造业产能过剩有进一步蔓延趋势。分行业类别看,产能过剩集中于重工制造业领域,而轻工业的产能过剩相对较少,且近半数轻工业行业存在一定程度的产能不足。从企业行为和市场与政府关系两个层面,提出了发挥市场机制决定性作用和更好发挥政府作用,共同化解产能过剩,促进江苏产业转型升级的政策建议。     

Foreign Institutional Ownership and the Global Convergence of Financial Reporting Practices

This paper investigates whether foreign institutional investors affect the global convergence of financial reporting practices. Using several measures of reporting convergence, we show that U.S. institutional ownership is positively associated with subsequent changes in emerging market firms’ accounting comparability to their U.S. industry peers. We identify this association using an instrumental variable approach that exploits exogenous variation in U.S. institutional investment generated by the JGTRRA Act of 2003. Further, we provide evidence of a specific mechanism—the switch to a Big Four audit firm—through which U.S. institutional investors affect reporting convergence. Finally, we show that, for emerging market firms, an increase in comparability to U.S. firms is associated with an improvement in the properties of foreign analysts’ forecasts.     

Earnings Metrics,Information Processing,and Price Efficiency in Laboratory Markets

An enduring issue in financial reporting is whether and how salient summary measures of firm performance (“earnings metrics”) affect market price efficiency. In laboratory markets, we test the effects of salient earnings metrics, which vary in how they combine persistent and transitory elements, on investor information search, beliefs about value, offers to trade, and market price efficiency. We find that including transitory elements in salient earnings metrics causes traders to search unnecessarily for further information about these elements and to overestimate their effect on fundamental value relative to a rational benchmark. In contrast, separately displaying persistent elements in earnings increases the accuracy of traders’ value estimates. Prices generally reflect traders’ beliefs about value, and prices are most efficient when transitory elements are excluded from earnings metrics entirely. Our study contributes to research on salience effects in financial reporting by showing that including transitory elements in salient earnings metrics causes inefficient information search and biased beliefs about value that can aggregate to affect market prices. We also contribute to research in experimental markets by showing that redundant disclosure is not always beneficial; redundant disclosure of transitory earnings elements, in particular, appears to have negative consequences for investor behavior and market efficiency.     

Short Selling Pressure,Stock Price Behavior,and Management Forecast Precision: Evidence from a Natural Experiment

Using a natural experiment (Regulation SHO), we show that short selling pressure and consequent stock price behavior have a causal effect on managers’ voluntary disclosure choices. Specifically, we find that managers respond to a positive exogenous shock to short selling pressure and price sensitivity to bad news by reducing the precision of bad news forecasts. This finding on management forecasts appears to be generalizable to other corporate disclosures. In particular, we find that, in response to increased short selling pressure, managers also reduce the readability (or increase the fuzziness) of bad news annual reports. Overall, our results suggest that maintaining the current level of stock prices is an important consideration in managers’ strategic disclosure decisions.
