State-owned enterprises going public The case of China

Public listing is a key reform measure for large state‐owned enterprises (SOEs) in China. We find evidence that public listing lowers state ownership significantly, lessens firms’ reliance on debt finance, and allows firms to increase capital expenditure, at least temporarily. We also find that ownership structure affects post‐listing performance. However, we find no statistical evidence of a positive effect of public listing on firms’ profitability. We suggest alternative interpretations of the last finding.     

责任导向会促进年长员工知识分享吗？基于主动动机模型

全球劳动力老化的严峻形势下,年长员工能否主动分享知识经验,对充分开发年长人力资本、促进企业可持续发展具有重要意义。基于主动动机模型,本文从责任导向视角探讨了年长员工知识分享行为的促发机制和边界条件。通过线性回归和蒙特卡洛拔靴法对200份40岁以上在职员工三时点配对数据进行分析,结果表明：责任导向会通过提升年长员工的建设性责任知觉进而激发其知识分享;反年龄歧视氛围感知对这一作用过程具有权变影响。本文丰富了年长员工知识分享行为的前因研究,对企业如何积极应对职场老龄化与年长员工知识传承具有启示意义。     

Do individual investors learn from their trading experience?

After analyzing retail investors’ stock trades for potential learning behavior, we present evidence that individual investors learn from their trading experience. Initially, we question whether investors’ previous forecasting ability (inferred from prior purchases’ subsequent risk-adjusted performance) affects their future trade profitability and activity. Indeed, as an investor's inferred ability increases, so does her ensuing trade profitability and intensity. Further, because additional investment experience allows more accurate ability inference, we posit that trading experience should help investors obtain better investment performance. Consistent with this hypothesis, not only do excess portfolio returns improve with account tenure, but we also find that trade quality (i.e., average raw and excess buy-minus-sell returns) significantly increases with experience (i.e., calendar time and account tenure). In sum, individual stock investors do learn, and they consequently adjust their behavior and thus effectively improve their investment performance.

试论信息技术与美术学科的课程整合

发展创造力及创新教育已成为当今知识经济时代的重要任务.高校美术教育作为培养创造力的最具成效的学科之一,在创新教育的开拓中更是责无旁贷.高校美术教育应进一步深化教学改革并创新发展,以适应创新教育的要求,信息技术教育与美术课程整合是现代教学发展的必然.随着素质教育的发展和教育信息化的推进,要求在教学中普及信息技术教育.而信息技术与课程的整合,是普及信息技术教育的关键,在学科教学中广泛应用信息技术手段,将信息技术和学科的教学过程紧密地结合起来,把信息技术教育融合在学科的学习中,把信息技术与学科教学整合在一起,是实现基础教育跨越式发展的必由之路.由此,信息技术为高校美术教育学的教学提供了良好的学习环境,让学生的主体地位得以真正确立,使自主学习、探索学习、协作学习得以真正实现,使终身教育和学习社会化成为可能.     

Does the cessation of quarterly earnings guidance reduce investors’ short-termism?

The practice of providing quarterly earnings guidance has been criticized for encouraging investors to fixate on short-term earnings and encouraging managerial myopia. Using data from the post–Regulation Fair Disclosure period, we examine whether the cessation of quarterly earnings guidance reduces short-termism among investors. We show that, after guidance cessation, investors in firms that stop quarterly guidance are composed of a larger (smaller) proportion of long-term (short-term) institutions, put more (less) weight on long-term (short-term) earnings in firm valuation, become more (less) sensitive to analysts’ long-term (short-term) earning forecast revisions, and are less likely to dismiss chief executive officers for missing quarterly earnings targets by small amounts, relative to investors in firms that continue to issue quarterly earnings guidance. Our study provides new evidence of the benefit of stopping quarterly earnings guidance, that is, the reduction of short-termism among investors.     

中国地区船舶工业技术效率差异及其变动趋势分析——基于Malmquist生产率指数

本文以3项投入(固定资产、船舶主要建造设施量、年平均从业人数)及2项产出(工业总产值、修正总吨)研究中国各省份船舶工业绩效表现,以2007～2009年各省船舶工业为研究对象,利用Super SBM模型进行超效率实证分析,通过Malmquist生产力指数研究各省船舶工业绩效变动趋势.研究结果发现:2007～2008年各省份生产力指数变化的主要原因是受技术效率变化的影响较大;而在2008～2009年生产力指数变化的主要原因是受技术变化的影响较大.在生产力指数分析上,整体来说,2007～2009年我国各省份船舶工业的全要素生产率呈现下滑趋势,其主要原因是由技术及效率变化交互影响带来的.

Dividend decisions in the property and liability insurance industry: mutual versus stock companies

This article examines the effect of organizational forms on corporate dividend decisions by exploring the differences in dividend payout ratios between mutual and stock property–liability (P–L) insurers in the US. Our large sample evidence suggests: (1) mutual insurers tend to have a lower dividend payout ratio than stock insurers and the observed difference is about 4% points, holding other factors constant; (2) mutual insurers tend to adjust dividend payout ratios toward their long-run target levels more slowly than stock firms. These results are consistent with the capital constraints and/or greater agency costs of equity in mutual insurers.
