This study investigates the relation between credit supply competition among banks and their clients’ conditional accounting conservatism (i.e., asymmetric timely loss recognition). The Interstate Banking and Branching Efficiency Act (IBBEA) of 1994 permits banks and bank holding companies to expand their business across state lines, introducing a positive shock to credit supply competition in the banking industry. The increase in credit supply competition weakens banks’ bargaining power in the negotiation process, which in turn may weaken their ability to demand conservative financial reporting from borrowers. Consistent with this prediction, results show that firms report less conservatively after the IBBEA is passed in their headquartered states. The effect of the IBBEA on conditional conservatism is particularly stronger for firms in states with a greater increase in competition among banks, firms whose operations are more concentrated in their headquarter states, firms with greater financial constraints, and firms subject to less external monitoring. Robustness tests confirm that the observed decline in conditional conservatism is causally related to the passage of IBBEA. Overall, this study highlights the impact of credit supply competition on financial reporting practices.

Description摘要

在复杂多变的商业环境中,企业传统的人力资源管理已经难以应对日益频发的员工职业倦怠、人际间矛盾冲突、频繁跳槽等局面与问题。企业员工工作的价值与意义早已不再是传统的雇佣模式下,通过出卖劳动力或智力从而获得工资以实现“养家糊口”的目的那么单纯与简单,员工也希望通过辛勤的工作,以获得个体的幸福感、荣誉感与认同感等。对于现代企业的管理者而言,员工追求事业的提升、个人价值的实现,不仅体现在薪酬、福利待遇的提升,更重要的是员工个人的成长以及潜能和竞争力的提升。

随着组织行为学和心理学的不断发展与演变,与员工幸福感相关的研究备受关注。对现代企业而言,管理者借助制度设计对员工幸福积极管理,可以最大限度地发挥员工的积极性、主动性与创造性,实现员工与企业之间的利益相趋同,从而更为高效地实现组织的目标。基于此,本文以民营企业员工工作幸福感作为研究的切入点,借助理论分析、问卷调查和实证分析相结合的研究方法,系统深入地研究我国民营企业员工工作幸福感的构成、可控前因和绩效后果等问题。

本文研究发现:

第一,员工薪酬的提高有助于员工工作幸福感的提升,薪资对基层员工幸福感的影响显著高于其对高层员工幸福感的影响;

第二,完善的晋升机制对于中层员工而言更能提升其幸福感,完善的晋升机制更有利于中层员工;

第三,公平性的提高有助于提高员工工作幸福感,而且这种正效应更多体现在基层员工群体之中;

第四,高层员工更注重自我价值的实现,高层员工的工作挑战性越高,其自我实现需求获得的满足感则约高,但是对于基层员工和中层员工而言,其效果则恰恰相反,基础员工和高层员工更多地将工作挑战性和压力看作是一种负面的因素;

第五,员工幸福感的确会给企业带来正向的绩效。

本文的研究框架和实证结论不仅可以丰富学术界有关员工工作幸福感的研究,而且为企业管理者进行绩效管理以及员工工作质量的提升提供理论和实证借鉴。

Description当前,上市公司的盈余管理问题已是我国资本市场中普遍存在的突出问题。一般来说,一些企业为了满足资本市场对于上市、增发等条件的要求,以及为有效推动企业的并购、重组等行为的顺利实现,甚至为了谋求公司管理层的个别利益,往往运用盈余管理等举措实施公司财报及关键指标的粉饰修正,让不知情的股民蒙受一定的损失。普遍分析显示,我国股市中民营企业比其他企业遭遇的问题和压力更多、更大、更突出,因此民营企业从客观上来说拥有更强的盈余管理动机。而从当前我国资本市场的实际情况来看,我国相关专家学者对盈余管理的系统性深入研究,一般都瞄准了上市企业群体或持续亏损企业,对盈余管理的研究不系统、不全面、不深入,这将对我国进一步提升盈余管理监管水平构成一定不利影响。当前,由于我国民企在自身管理及发展动力方面的特殊性,我国民企的管理、盈余管理特点和国外上市公司还存在着很大的不同,进一步深入研究我国民企上市公司自身管理方面的突出特点,以及其对企业盈余管理等方面的深层次影响,有助于监管层对症下药,更有针对性地研究出台全新的监管措施,进一步提升管理水平。这还可以为公司发展的决策层及相关会计信息使用人员提供一定的决策参考, 因此其拥有十分重要的意义。

本文首先认真总结分析了有关上市企业治理结构和盈余管理等方面的历史文献资料,依托当前资本市场上普遍运用的委托代理、内部人控制和契约等理论,系统研究了我国民企上市公司在自身治理结构方面的突出特征以及其对盈余管理方面所构成影响的深层次原理。在此基础上,本文通过2015-2017年我国上市企业数据,基于截面Jones模型对民营企业和非民营企业盈余管理程度进行测算和比较分析,发现民营企业盈余管理程度更高;从四个层面系统研究民企公司自身的治理结构突出特点,设立回归模型论证了民营企业独特的公司治理结构特征对盈余管理程度确实会产生影响;最后,本文进一步利用修正的费尔萨姆一奥尔森估价模型对民营上市公司盈余管理有公司价值的关系进行了验证,发现两者具有显著相关性。

Description本文采用2010年1月1日至2017年12月31日在香港主板IPO上市的共574家公司作为研究样本,系统采集包括与发行人、承销商、投资人、发行热度、市场每日交易数据等相关的数据近100项,对超额配售选择权在香港IPO中的实际效用进行实证研究,研究发现:1)超额配售选择的确可以起到提高发行价格,降低IPO抑价率的作用,但是同时也是破发的主要原因。2)由超额配售选择权赋予承销商稳价行为中,市场买入量越大,最大回撤越大,市场下跌风险越大同时超额配售选择权还导致了最大回撤日的推后,增大了稳价结束后的市场风险,而这很有可能是由于承销商追求更高利益造成的。3)没有证据显示,超额配售选择权会降低承销商的佣金比例,但是,超额配售选择权却为承销商带来非常高的额外收益,而这个收益与市场下跌幅度和承销商从市场购买股份的比例直接相关。

其中,本文首次对最大回撤率、最大回撤日与承销商市场买入量之间的关系进行实证研究,揭示了承销商市场买入量与承销商收益正相关,与最大回撤率负相关,与最大回撤日正相关的关系,可能是增加市场下跌风险的因素。这与现有理论中及监管机构的预期中,“超额配售选择权具有向上稳定价格的作用”是有一定偏差的。

根据研究结果,本文首先建议发行人要客观对待超额配售选择权提升发行价格的作用,以免引起破发。其次建议市场投资人要客观认识超额配售选择权的作用,不要由于超额配售选择权的存在给与发行过高的认同价格。再次建议发行人要能够认识到超额配售选择权是承销商零成本获得的一个有固定收益保障的看空期权,是承销商在承销IPO时的收益之一,而股价下跌幅度与承销商的收益正相关。因此要对承销商的稳价行为进行一定管控,同时可以因为超额配售选择权的存在而要求更低的承销佣金比例。最后建议承销商要维护市场公平,爱护自己的声誉,尽可能避免因超额配售选择权的使用对市场造成不应有的干扰。

Description近些年来,我国城市化进程不断加快,到2020年我国常住人口城镇化率将达到60%左右,户籍人口城镇化率将会达到45%左右。伴随着我国城市化进程的高速推进以及经济水平的不断提高,公共物品及服务的需求程度加大,政府单独出资建设公共项目会导致资金不足、经营管理效率低下等问题。与此同时,我国当前不同层级地方政府的政府性债务都达到了一个非常高的水平,截至2017年末,中国地方政府债务16.47万亿元,债务率(债务余额/综合财力)为76.5%,其中地方负有偿还责任的债务约12.9万亿,地方政府性债务的控制和转化成为经济新常态下重要特征之一。在地方债务压力较大的情况下,PPP将替代土地财政和地方政府融资,为我国新型城镇化建设提供可持续的资金支持,PPP模式成为当前城市建设领域融资的重要选项。

据此,本文基于实证研究方法探讨在债务约束的背景下,在地方政府债务约束下,PPP模式的引入,对城市规划中建设用地面积、人口规划规模与容量、建设用地属性等的城市规划变量的影响;与此同时,考虑到地方政府的政策很大程度上受到是由地方官员,特别是受到作为地方政府党政“一把手”的市委书记和市长的晋升压力和激励的影响,讨论市委书记/市长的晋升压力和激励对PPP模式引入效果的影响。研究发现,在地方政府债务约束下,PPP模式的引入,显著增加城市规划中建设用地面积、人口规划规模与容量、建设用地属性等的城市规划变量;同时,地方政府官员存在利用PPP放大城市建设和规划规模的行为,反映了PPP项目在引入和使用的过程中很大程度上受政府官员的激励的影响。

Description基于中国人口老龄化加速、目前人均医疗支出偏低和国内医疗器械企业以中低端产品

为主的局面,中国的医疗器械行业正面临着巨大的发展机遇,投融资活动将迎来爆发式增

长。 在此背景下, 医疗器械企业的估值研究对投融资双方都有较大的意义。

我们假设医疗器械公司的产品差异度对其公司的估值有正面影响。

产品差异度定义为:该产品区别于其他竞争性产品的独特性,由以下六个方面构成:

产品唯一性水平、先进性(器械类别、优秀国产医疗设备个数、产品的专利化程度)、利润

边际和其市场容量,并对此用 12 个指标做出了定量的估计。本研究主要的数据来源是上市

的医疗器械公司,因为这些公司的相关数据取得比较容易且数据客观性较强。我们使用一

般回归分析测量产品差异度与公司估值之间的关系。在得出正面的回归结果之后, 我们采

用双重差分分析(DID)方法,验证实际情形下新产品相关信息发布对公司股价波动的影响。

根据回归分析结果:

1、 “产生营收的产品唯一性水平”和“边际利润”与市值有显著相关性: 说明医疗器械

类企业确实是核心产品驱动发展的, 产品唯一性程度高(已剔除那些已逐渐被市场淘汰的

产品) 说明市场定价能力强, 边际利润率高,盈利能力强, 进而对公司估值形成正面影

响。

2、 “”净利润“和”“互联网概念”与市值也呈现显著相关性。净利润的相关性是显而易见

的。互联网概念的相关性体现了互联网+医疗成为近几年市场的风口。

iv

3、 其他一些指标未呈现明显的相关性,有可能是因为我们的数据量太少引起的, 也

有可能还有其他未在我们考虑范围内的因素导致的,也可能是因为中国目前的股票市场还

未到达半强式有效市场。这可能对其他行业的影响也是如此。

在后面进行的实证分析中, 除个别情况外,我们发现公司重磅新产品相关信息的发布

基本上对公司之后 1-30 个交易日的股价起到了较明显的推动作用。

The inherent risk in testing drugs has been hotly debated since the government first started regulating the drug industry in the early 1900s. Who can assume the risks associated with trying new pharmaceuticals is unclear when looked at through society's lens. In the mid twentieth century, the US Food and Drug Administration (FDA) published several guidance documents encouraging researchers to exclude women from early clinical drug research. The motivation to publish those documents and the subsequent guidance documents in which the FDA and other regulatory offices established their standpoints on women in drug research may have been connected to current events at the time. The problem of whether women should be involved in drug research is a question of who can assume risk and who is responsible for disseminating what specific kinds of information. The problem tends to be framed as one that juxtaposes the health of women and fetuses and sets their health as in opposition. That opposition, coupled with the inherent uncertainty in testing drugs, provides for a complex set of issues surrounding consent and access to information.

Breast microcalcifications are a potential indicator of cancerous tumors. Current visualization methods are either uncomfortable or impractical. Impedance measurement studies have been performed, but not in a clinical setting due to a low sensitivity and specificity. We are hoping to overcome this challenge with the development of a highly accurate impedance probe on a biopsy needle. With this technique, microcalcifications and the surrounding tissue could be differentiated in an efficient and comfortable manner than current techniques for biopsy procedures. We have developed and tested a functioning prototype for a biopsy needle using bioimpedance sensors to detect microcalcifications in the human body. In the final prototype a waveform generator sends a sin wave at a relatively low frequency(<1KHz) into the pre-amplifier, which both stabilizes and amplifies the signal. A modified howland bridge is then used to achieve a steady AC current through the electrodes. The voltage difference across the electrodes is then used to calculate the impedance being experienced between the electrodes. In our testing, the microcalcifications we are looking for have a noticeably higher impedance than the surrounding breast tissue, this spike in impedance is used to signal the presence of the calcifications, which are then sampled for examination by radiology.

Breastfeeding has been shown by a number of studies to have numerous benefits on both the mother and the infant. Major health organizations such as the World Health Organization (WHO), now agree that breastfeeding should be encouraged and supported in all countries. But like many things, the wheels of the law are slow to catch up with scientific evident. Although breastfeeding is supported, working women do not have the option of breastfeeding without consequences. For example, in 2003, Kirstie Marshall, a then member of parliament in Australia was ejected from the lower house chamber on February 23, for breastfeeding her baby [3]. According to standing order 30 at the time, "Unless by order of the House, no Member of this House shall presume to bring any stranger into any part of the House appropriated to the Members of this House while the House, or a Committee of the whole House, is sitting" [3]. The rules did not specify the age of strangers, so the then 11-day-old baby, Charlotte Louise and her mother were shown the exit door of parliament. She had to choose between being present at times of major discussions or leaving the house to breastfeed her child, she chose to leave. More recent statistics show that developed nations like the US and Australia which also have high rates of women employment had low rates of breastfeeding. This might mean that workplace policies do not favor breastfeeding or expressing milk at work. Fortunately, laws have since been introduced in both the United States and Australia that support breastfeeding at the workplace. The next step would be to access how these laws affect breastfeeding statistics and how variation between these two countries like the paid parental leave in Australia (which is not present in all US states) would affect these numbers.

Social-emotional learning (SEL) methods are beginning to receive global attention in primary school education, yet the dominant emphasis on implementing these curricula is in high-income, urbanized areas. Consequently, the unique features of developing and integrating such methods in middle- or low-income rural areas are unclear. Past studies suggest that students exposed to SEL programs show an increase in academic performance, improved ability to cope with stress, and better attitudes about themselves, others, and school, but these curricula are designed with an urban focus. The purpose of this study was to conduct a needs-based analysis to investigate components specific to a SEL curriculum contextualized to rural primary schools. A promising organization committed to rural educational development is Barefoot College, located in Tilonia, Rajasthan, India. In partnership with Barefoot, we designed an ethnographic study to identify and describe what teachers and school leaders consider the highest needs related to their students' social and emotional education. To do so, we interviewed 14 teachers and school leaders individually or in a focus group to explore their present understanding of “social-emotional learning” and the perception of their students’ social and emotional intelligence. Analysis of this data uncovered common themes among classroom behaviors and prevalent opportunities to address social and emotional well-being among students. These themes translated into the three overarching topics and eight sub-topics explored throughout the curriculum, and these opportunities guided the creation of the 21 modules within it. Through a design-based research methodology, we developed a 40-hour curriculum by implementing its various modules within seven Barefoot classrooms alongside continuous reiteration based on teacher feedback and participant observation. Through this process, we found that student engagement increased during contextualized SEL lessons as opposed to traditional methods. In addition, we found that teachers and students preferred and performed better with an activities-based approach. These findings suggest that rural educators must employ particular teaching strategies when addressing SEL, including localized content and an experiential-learning approach. Teachers reported that as their approach to SEL shifted, they began to unlock the potential to build self-aware, globally-minded students. This study concludes that social and emotional education cannot be treated in a generalized manner, as curriculum development is central to the teaching-learning process.
