上市公司股权再融资盈余管理行为的实证分析

本文运用横截面修正的Jones模型,对我国1997—2002年A股上市公司配股盈余管理行为作了实证分析。研究发现,配股前3个年度和配股当年存在系统的盈余管理行为,影响了上市公司资本配置效率,并导致配股后上市公司业绩出现下降。会计师对于盈余管理进行了必要的关注,说明融资后的审计意见报告具有一定的质量。     

上市公司配股过程中的负向盈余操纵问题

一、上市公司配股时是否存在负向盈余操纵 配股中的盈余操纵一直是我国学界关注的重大问题.蒋义宏、魏刚(1998)较早关注了配股中盈余操纵的存在性问题,他们通过考察上市公司ROE的分布变化与配股政策的相关性,发现ROE的分布与配股政策具有高度的相关性,配股边际区间内公司数量高度密集,上市公司存在通过盈余操纵获取配股资格的问题,许多后续研究都围绕着这一思路展开.     

配股后业绩下滑与真实活动盈余管理的相关性研究

本文以我国1997-2009年成功实施配股的549家A股上市公司为样本,从真实活动盈余管理的角度,实证检验了公司为达到证监会的配股资格线,是否进行了盈余管理,以及此行为对公司配股后的经营业绩所产生的影响。研究结果表明,上市公司在配股前确实进行了真实活动盈余管理,且此行为与公司配股后的业绩显著负相关。     

上市公司配股盈余管理之规范分析

配股融资历来受到上市公司的青睐。为达到中国证监会的ROE标准,上市公司通过各种手段进行利润调整,从而产生了配股盈余管理现象。配股盈余管理主要是上市公司在配股融资的过程中,为了达到政府有关的配股融资标准,在公认会计原则的约束下进行调节盈余的行为。它是在中国特有的融资环境中所产生的一种盈余管理行为。盈余管理在短期内有助于提高上市公司的股票价格,但长期上会导致股票价格的不稳定,从整个资本市场来看,融资盈余管理带来的是有限的资金资源没有合理的利用,甚至可能出现"劣币驱逐良币"的现象。

股权再融资、盈余管理与资本配置效率

本文建立了一个模型来分析股权再融资过程中盈余管理产生的机理，分析了盈余管理与配股后运营业绩和股票长期收益的关系。研究表明：上市公司在配股过程中存在系统的盈余管理行为；上市公司配股后的经营业绩出现滑坡，配股前3个年度和配股当年的异常应计利润与配股后的经营业绩具有负相关关系；上市公司配股后的股票长期收益和异常收益下降，配股前3个年度和配股当年的异常应计利润与配股后的股票收益具有负相关关系。本文认为，上市公司配股过程中的盈余管理误导了投资者的决策，造成了股票价值的高估和资本配置效率的下降。     

配股后业绩下降：盈余管理后果与真实业绩滑坡

本文研究了我国1998—2001年间上市公司首次配股后会计业绩下降的现象。实证结果表明,配股公司在配股前存在盈余管理行为,无后续融资行为公司配股后业绩下降且操控性应计利润在配股后发生反转,这为配股前盈余管理机会主义观提供了直接证据；有后续融资行为公司在配股后仍进行盈余管理以继续尽可能维持较高业绩。这两类公司配股后现金流的减少表明,配股前盈余管理仅能为配股后业绩下降提供部分解释。本文研究发现意味着,限制公司管理层在配股前的盈余管理机会主义行为,并非避免配股后业绩下降的唯一手段,如何提高配股后资金使用效率应该是保护投资者利益的又一重要方面。     

上市公司再融资经营业绩研究

一、引言由于我国特殊的股权结构、融资监管体制,上市公司的融资行为具有更复杂的制度背景,这就使得上市公司的再融资行为具有不同的意义。国内上市公司的融资政策和融资行为,理论界还缺乏系统的研究,公司融资行为的研究更多围绕着再融资的盈余管理问题,对再融资上市公司本身的业绩也很少关注。因此,本文将对配股、增发上市公司的业绩进行深入研究,以期为研究上市公司股权再融资问题提供借鉴。     

并购、盈余管理与制度背景

对上市公司并购的制度背景和盈余管理的制度背景分析发现,上市公司在我国目前特殊的制度背景下在并购中进行盈余管理是一种理性行为。在政府主导下进行的无效率的并购和为了获得配股资格而在并购前期调高利润的盈余管理行为是导致其并购后期经营业绩下降的主要原因。     

新配股政策出台后上市公司盈余管理现象的实证研究

本文采用直方图法和概率密度函数法相结合的方法,在对每个上市公司连续三年的ROE分布情况进行跟踪观察的基础上,研究了新配股政策出台后上市公司的盈余管理现象,并揭示了盈余管理的特征。     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.     

Cost accounting standard and cost accounting systems in Japan. Lessons from the past - recovering lost traditions

This paper aims to show two things. The first is how Japanese culture has contributed to the development of Japanese cost accounting history. The second is to reveal the research possibilities of cost accounting history. This paper also reviews the salient features of several important examples of these aspects of cost accounting practice in Japan. It therefore explores, through some practical illustrations, how and why Japanese cost accounting differs from that found in the West.

Bayesian Premium Rating with Latent Structure

We propose a fully Bayesian approach to non-life risk premium rating, based on hierarchical models with latent variables for both claim frequency and claim size. Inference is based on the joint posterior distribution and is performed by Markov Chain Monte Carlo. Rather than plug-in point estimates of all unknown parameters, we take into account all sources of uncertainty simultaneously when the model is used to predict claims and estimate risk premiums. Several models are fitted to both a simulated dataset and a small portfolio regarding theft from cars. We show that interaction among latent variables can improve predictions significantly. We also investigate when interaction is not necessary. We compare our results with those obtained under a standard generalized linear model and show through numerical simulation that geographically located and spatially interacting latent variables can successfully compensate for missing covariates. However, when applied to the real portfolio data, the proposed models are not better than standard models due to the lack of spatial structure in the data.
