并购商誉、商誉减值与股票错误定价

以近年来上市公司频发的并购重组为背景,选取2007—2019年我国沪深A股上市公司为研究样本,实证检验了并购商誉对股票错误定价的影响。研究发现,商誉加剧了并购方的股票错误定价,高商誉的公司股价被严重高估,计提商誉减值能够向投资者传递增量信息,缓解商誉导致的股票错误定价。进一步研究发现,会计稳健性和投资者情绪在并购商誉对股票错误定价的影响中发挥了部分中介作用。商誉对股票错误定价的影响在管理层持股高、分析师跟踪人数多的情况下更为显著,上市公司大股东及管理层存在利用并购商誉导致的股价高估实现高位减持的行为。研究结论有助于投资者对并购商誉正确定价,提高资本市场定价效率。     

机构投资对我国资本市场资产价格影响的实证研究

本文以1999年3月到2011年3月的沪深主板上市公司月收益率为样本,通过定义机构投资者的投资策略,对加入机构投资者影响后的CAPM扩展模型进行实证研究,发现扩展模型消除了经典CAPM中存在的异方差性,且不存在一阶自相关性;资产组合的收益率同市场组合收益率呈反比关系,与基准投资组合收益率呈正比关系;模型拟合度有了很大的改善。机构投资对我国资本市场资产价格产生了积极的影响。因此,我国资本市场应该大力发展机构投资者,机构投资者本身也应该朝着健康的方向发展。     

Contracts for dummies? The performance of investors in contracts for difference

Investors widely use contracts for difference (CFDs) to leverage and short sell underlying financial assets. We investigate the after cost performance of investors in Australian Securities Exchange listed share CFDs, and find that market order CFD trades earn small positive returns at the daily horizon, with negative returns reported for one month to one year horizons due to financing costs. Market orders also net sell positions, which suggests that investors use CFDs for shorting opportunities. Overall, we find that liquidity demanders in CFDs obtain favourable execution, which is inconsistent with the view that CFDs are used by naive individuals.     

Common Institutional Ownership and Earnings Management*

This study examines the relation between earnings management and block ownership of same‐industry peer firms by a common set of institutional investors (common institutional ownership). This relation is important given the tremendous growth of common institutional ownership and the significant influence of blockholders on financial reporting. We hypothesize that common institutional ownership mitigates earnings management by enhancing institutions' monitoring efficiency and by encouraging institutions to internalize the negative externality of a firm's earnings management on peer firms' investments. Consistent with our hypothesis, we find that higher common institutional ownership is related to less earnings management. Analyses of a quasi‐natural experiment based on financial institution mergers show that this negative relation is unlikely to be driven by the endogeneity of common institutional ownership. Cross‐sectional tests provide evidence that the negative relation is stronger among firms for which common institutional ownership is likely to generate a greater reduction in institutions' information acquisition and processing costs, and among firms whose severe financial misstatements are more likely to distort co‐owned peer firms' investments, supporting both mechanisms underlying our hypothesis. Our findings inform the ongoing debate on the costs and benefits of common institutional ownership by highlighting an important benefit: the enhanced monitoring of financial reporting.     

异质性、机构投资者与会计稳健性

以2000—2011年沪深A股上市公司为样本,基于企业本身和市场异质性的视角,考察机构投资者持股对会计稳健性的影响,结果发现：机构投资者持股比例的提升会导致企业会计稳健性的下降,在国有企业、成长性较好的企业中这种负向关系增强了,而企业所处地区的市场化程度对机构投资者持股与会计稳健性之间的负向关系无显著影响,此外,相比“压力抵制型”机构投资者而言,“压力敏感型”机构投资者持股比例的上升导致会计稳健性下降更快。     

企业税收遵从行为影响因素研究:公司治理的视角

公司盈余管理是财务管理的一个重要研究方向,而税收又是公司盈余管理的重要手段,因此对企业税收遵从行为的研究就成为公司理财的重要内容。本文从研究Weisbach教授提出的公司税收遵从之谜开始,分析了企业税收遵从行为的影响因素。从投资者反应、公司治理水平、税收政策等几个方面探讨了影响企业税收遵从的作用方式和程度。

The path to Project Darwin: The evolution of the AMP's organisational structure

Demutualisation became a global trend amongst financial sector firms in the last two decades of the twentieth century. Changes to the organisational foundations of mutual firms represented a shift in operational cultures and have often been viewed as an end point or demise of the co-operative business model. It is the intention of this article to investigate the extent to which this was the case within a major mutual institution, the Australian Mutual Provident, Australia's oldest and largest mutual insurer. The article's key argument is that the concept of mutuality is organic, and that within this organisation it evolved as the structure of the firm became more sophisticated as it developed from a supplier of life insurance products into a sophisticated financial services provider, which ultimately generated internal pressures to demutualise.     

议对外商非法撤资的法律规制

进入2008年以后,我国部分地区却密集出现了较为严重的外商非法撤资的情况。非法撤资对当地经济更是雪上加霜,同时造成了企业职工、中方合作者、企业供货商等相关权益人的巨大利益损害。本文通过介绍非法撤资的现状,分析了非法撤资产生的原因以及带来的危害,进而讨论了对非法撤资的法律规制途径,希望能够提出一些有价值的建议。
