紫花鸢尾的细胞学研究

本文报道了紫花鸢尾体细胞的染色体数目,除观察到正常的 2 倍体2n=24外,还发现有 2n=23,2n=22 等非整倍性变异,核型公式为:K(2n)=2x=24=6m+6sm+8st+4t,核型为“3B”型,核型不对称系数为 73.35％,染色体相对长度组成为:2n=24=4L+4M_2+·14M_1+2s,染色体总体积为 73.05μm~3。     

Blockholder Exit Threats and Financial Reporting Quality

Recent theoretical and empirical studies suggest that blockholders (shareholders with ownership ≥ 5 percent) exert governance through the threat of exit. Blockholders have strong incentives to gather private information and sell their shares when managers are perceived to underperform. To prevent blockholders from selling their shares and the firm from suffering a stock price decline, managers align their actions with the interests of shareholders. As a result of the greater manager‐shareholder alignment, managers' actions are more likely to be in shareholders' best interest, and consequently there is less need for managers to manipulate earnings. Consistent with these predictions from economic theory, we find evidence that as exit threat increases, firms have higher financial reporting quality. Theory also predicts that the impact of blockholders' exit threat on financial reporting quality (FRQ) should increase as the manager's wealth is tied more closely to the stock price, and this is what we find. Our study contributes to the research on the impact of shareholders on FRQ and to an emerging literature on the impact of blockholders in financial markets. Blockholders play an important role in managers' reporting outcomes through their actions as informed investors.     

Do Analysts Matter for Corporate Tax Planning? Evidence from a Natural Experiment

We exploit an exogenous shock to analyst coverage as a result of brokerage house mergers and closures to examine whether financial analysts influence the tax‐planning activities of the firms they cover. Using a difference‐in‐differences design, we find that, on average, firms affected by broker mergers and/or closures experience a reduction in their GAAP (cash) effective tax rates (ETR) of 2.5 percent (2.6 percent), relative to control firms, translating into average tax expense (cash tax) savings of $34 ($35) million. The treatment effect is more pronounced among firms with lower pre‐event analyst coverage. To explore how analysts affect tax planning, we further document that the treatment effect is greater among firms that lose an analyst who provided an implied ETR forecast in the past, suggesting that analysts influence tax planning via their tax‐specific research efforts. In addition, we find that after merger/closure, weakly governed firms increase their use of aggressive tax strategies, and financially distressed firms experience a larger reduction of cash effective tax rates, relative to control firms. Overall, we provide evidence that a shock to analyst coverage sufficiently changes the cost‐benefit trade‐off of tax planning.     

Age heaping and numeracy: looking behind the curtain

Age‐heaping‐based numeracy indicators have served as valuable tools to derive basic human capital estimates, especially for periods where other indicators are unavailable. However, the accuracy of individual age statements usually remains unknown, and due to the lack of precise information it can only be assumed that excessive occurrence of multiples of five in age distributions reflects inferior numerical skills. This article addresses this lacuna by identifying 162 individuals in two independent data sources: self‐reported age statements and independently kept records which are based on family heritage books and church registers. This method makes it possible to identify individual misreporting and the degree of accuracy of each individual. Findings show that not everyone who reported a multiple of five was reporting an incorrect age, nor was it the case that everyone who reported an age that was not a multiple of five was reporting an accurate age. The empirical analysis shows that the commonly used binary numeracy indicator is correlated with the observed degree of accuracy in age statements, and that a more sophisticated occupational background reduces this inaccuracy. These results tentatively suggest that the commonly used binary indicator measuring age heaping is a valuable proxy for numerical skills and occupational background in a population.     

我国机构投资者行为与证券市场稳定研究

近来，有关部门提出了超常规培育机构投资者的证券市场监管政策，认为机构投资者能稳定证券市场，提高证券市场运行效率。但是，机构投资者并不必然能稳定证券市场，市场的稳定还需要一定的制度环境。     

企业员工组织承诺和工作绩效的相关研究

本研究以浙江绍兴某集团下属的5个子公司的320名企业员工为研究时象,根据调查问卷数据,分析发现:在规范承诺与继续承诺方面,不同学历和工龄员工具有显著差异.在情感承诺方面,不同工龄的员工显著差异.学历显著影响着人际互动、职业道德与工作效能.不同工作地点员工在规范承诺、继续承诺之间差异显著,但是与情感承诺无关.工作地点与工作绩效的各个维度都有显著差异.组织承诺各维度与工作绩效各维度之间存在显著相关.本文还尝试分析了增强企业员工情感承诺和规范承诺以提高员工工作绩效的相应措施.     

以扩大内需促进就业问题研究

随着我国经济进入新的发展阶段后,投资对劳动力逐渐显现出排挤作用,出口也由其发展前景受限而对劳动力的吸纳作用减弱。而内需由于其对劳动密集型产业产品的需求,对就业有很强的带动作用。本文将论述以内需扩大就业的必要性,找出其中存在的问题,并提出相应建议。
