过度自信调节下董事会人力资本与企业R & D投入关系研究

结合资源依赖理论及冲突理论,以2013-2014年中国创业板149家企业为样本,运用回归分析法考察了董事会人力资本对企业R&D投入的影响,探讨了管理者过度自信在这一过程中的调节作用。结果显示：董事会人力资本广度与企业R&D投入强度显著负相关;②董事会人力资本深度与企业R&D投入强度显著正相关;③管理者过度自信对董事会人力资本深度和广度与企业R&D投入之间的关系皆具有显著的负向调节作用,即管理者过度自信程度越高,董事会人力资本深度对企业R&D投入的促进效用越小,其广度对企业R&D投入的消极作用越强。     

Does network board capital matter? A study of innovative performance in strategic SME networks

This article examines the effects of network board capital (i.e., human capital and relational capital) on total, radical and incremental network innovative performance. Results from a five-year longitudinal study of network boards in 53 strategic networks suggest that a network board's diversity, education level, and interlocking directorates with other such networks affect network innovative performance. The degree of board diversity and interlocking directorates primarily influence incremental innovation, whereas education level influences radical innovation. The study finds that a network board's diversity of expertise and education level are important for improving all components of innovative performance (total, radical and incremental) in smaller networks. Managerial implications of these findings are discussed.     

Using demographic identification to estimate the effects of board size on corporate performance

Motivated by agency theory, we investigate the effect of board size on corporate outcomes. To address endogeneity, we exploit the variations in the director-age populations across the states in the US. We argue that firms with access to a larger pool of potential directors tend to have larger boards. Consistent with this notion, our empirical results show that firms located where the size of the director-age population is larger have significantly larger board size. Because the director-age population represents broad demographic trends outside of any firm’s control, it is unlikely related to firm outcomes or policies and should be exogenous. Using the director-age population as our instrument, we estimate the effects of board size on firm value and profitability. Our approach is less vulnerable to endogeneity and is more likely to show a causal effect.     

证券市场机构违法违规均衡概率分析

近几年来，证券市场普遍存在的违法违规现象极大地挫伤了中小投资者的积极性。通过对证券市场参与主体行为进行经济学模拟，建立证监会和机构混合博弈模型，可得出均衡违法违规概率。此外，通过对均衡概率决定因素的定性分析，指出均衡违法违规概率偏高及其原因来自于证券市场不合理的博弈规则。     

流动性陷阱与利率调节——货币政策对投资、产出、就业无效吗？

运用利率期限结构分析1997年底出现通货紧缩以后的以利率调节为表征的货币政策效果,可以得出中国没有出现“流动性陷阱”的结论。通过相关分析得出利率连续下调等货币政策操作对投资、产出、就业的积极效应,否定在通货紧缩期间货币政策弱效或者无效的结论。     

股权结构、董事会特征与QFII持股的实证分析

通过对股权结构、董事会特征与QFII持股关系的研究,发现管理层持股比例、第一大股东持股比例、审计委员会设立状况以及公司规模与QFII持股显著正相关,独立董事比例、净资产收益率与公司成长性与QFII持股均没有显著关系。结果说明完善公司治理对于中国引入相关QFII有着重要作用。     

上市公司大股东与监事会治理

大股东所有权性质和持股比例都会对监事会治理产生影响。通过实证分析，得出重要结论：第一大股东的所有权性质不同，会对监事会治理绩效产生不同的影响；由大股东的持股比例不同所引致的代理权争夺，更有利于监事会治理绩效的改善。     

Do gender diverse boards enhance managerial ability?

We examine the link between board gender diversity and managerial ability to transform corporate resources into revenue. Drawing on a sample of U.S firms during the period 2001–2016, we find a positive and economically meaningful association between female directors on boards and managerial ability, particularly when female directors are in monitoring roles on the board. The documented effect is stronger when using a tenure weighted measure of female representation on boards; and more pronounced for firms that have three or more women on the board of directors, in line with the critical mass hypothesis. We uncover that critical mass of female directors in monitoring roles is particularly conducive to enhancing managerial ability. Our channel analysis tests further reveal a distinctive tendency of firms with more gender diverse boards to shape the human capital of the firm by promoting managers with more generalist managerial skills. We find consistent results when we employ propensity score matching estimates and difference-in-differences using sudden deaths of female directors as a potential shock to address endogeneity concerns. We discuss implications for theory and policy.     

A note on board characteristics,ownership structure and default risk in Taiwan

This study applies dynamic generalized method of moments estimation to examine the influences of ownership structure and board characteristics on default risk for a full samples and two subsamples (high‐tech and conventional) of publicly listed firms in Taiwan. Our findings reveal that certain characteristics of corporate governance have explanatory power for default probability, but the impact is not straightforward. In particular, the impact of internal and external governance structures on default risk is industry dependent. Accordingly, governance proposals that encourage higher ownership among directors and large block shareholdings in high‐tech firms or reduce managerial ownership in conventional companies can have a counterproductive effect on corporate governance and result in higher bankruptcy possibility.     

中小板市盈率投资组合与股票收益研究

中小板企业上市后业绩下滑,并未表现出与其高水平市盈率相匹配的成长性。通过构建市盈率投资组合,对比分析后发现企业的高市盈率可能是由于相对于其股价而言,每股盈余较低所致;基于低市盈率的投资组合投资策略具有高收益、低风险的特点,我国中小板市场存在市盈率效应,但不能被规模效应所解释。该研究结果为中小板市场的研究提供了经验数据,结论对于中小板投资者具有一定的启示意义。
