管理者行为、企业生命周期与非效率投资

本文从企业生命周期视角研究管理者代理行为和管理者过度自信对企业非效率投资的动态影响。选取2012-2015年深沪主板上市公司数据进行实证检验,结果表明:随着企业生命周期的发展,管理者代理行为逐渐加强,管理者过度自信水平却逐渐减弱。管理者代理行为和过度自信共同导致企业非效率投资,成长期阶段的企业非效率投资主要受管理者过度自信的显著影响,管理者代理行为对企业非效率投资影响不显著;成熟期阶段的企业非效率投资既受管理者代理行为的显著影响,也受管理者过度自信的显著影响;衰退期阶段的企业非效率投资则主要受管理者代理行为的显著影响,管理者过度自信对企业非效率投资影响不显著。     

管理者非理性行为与非效率投资关系研究

本文基于有限理性假设,以中国A股上市公司2009-2015年财务数据作为研究样本,研究管理者的三种非理性行为(管理者过度自信、管理者风险偏好和管理者从众行为)对企业非效率投资的共同影响。结果表明:管理者过度自信与管理者从众行为会导致上市公司非效率投资;过度自信和非过度自信管理者的从众行为均会加剧企业非效率投资,非过度自信管理者的从众行为对非效率投资的影响尤为严重;过度自信管理者的风险偏好与非效率投资显著正相关,而非过度自信管理者的风险偏好与非效率投资显著负相关,即非过度自信管理者适当的风险偏好行为在一定程度上会缓解企业非效率投资。因此,要想提高公司非效率投资管理应从管理者的心理素质培养入手,重点培养其避免从众心理,积极主动地根据自己企业的实际情况进行投资;对非过度自信的管理者还需要培养其适当的风险偏好。     

海归高管抑制了股价崩盘风险吗？

以我国A股上市公司2009—2017年数据为样本,研究高管的海外经历对公司未来股价崩盘风险的影响。发现海归高管有助于降低公司未来股价的崩盘风险,在多种稳健性检验并控制内生性问题后,以上结论仍然成立。另外,海归高管降低股价崩盘的效果在分析师关注较少的企业以及外部审计质量较弱的企业中表现得更加明显。机制分析表明,海归高管通过降低公司过度投资以及提高会计信息质量来抑制股价崩盘风险。     

过度投资对企业股价崩盘风险的影响研究——基于货币政策视角

本文从货币政策角度出发探讨过度投资与股价风险之间的关系,采用面板OLS模型进行回归.研究发现:(1)过度投资会累积资产泡沫,在坏消息或者不良预期下加大股价崩盘风险;(2)紧缩的货币政策可以通过改善公司治理抑制过度投资以及非效率投资,通过过度投资起到反向调节效应,降低股价崩盘风险.本文将货币政策与过度投资和股价风险放在一个框架中展开研究,宏微观相结合,可以为金融市场去杠杆化、加强宏观审慎监管、防范金融风险提供参考.     

儒家文化与股价崩盘风险

本文从非正式制度视角考察了儒家文化对公司股价崩盘风险的影响效应及作用机理。研究发现,公司受到儒家文化的影响程度越强,其股价崩盘风险越低。渠道分析表明,儒家文化主要通过抑制管理者自利动机、改善公司信息质量及降低管理者过度自信三条路径影响股价崩盘风险。进一步研究发现,儒家文化对股价崩盘风险的抑制作用在公司治理较弱和外部信息环境较差的情况下更加明显。这表明,儒家文化作为正式制度的一种隐性替代治理机制,对于防范股价崩盘风险、促进资本市场健康发展具有重要积极作用。本文不仅丰富了股价崩盘风险影响因素的研究,也深化了对儒家文化现代商业价值的理论认知。     

基于制度环境视角的非效率投资与股价崩盘风险研究

研究宏观层面的治理因子对企业非效率投资的调节作用,进而研究价格崩盘的成因。发现：较高的市场化进程、较低的政府干预程度和完善的法治环境都有助于抑制由非效率投资行为引发的股价崩盘风险。进一步的研究表明,企业非效率投资主要由代理成本而非信息不对称问题产生,进而影响价格崩盘;国有企业非效率投资对股价崩盘风险的影响大于非国有企业,但是制度环境的抑制作用对国有企业样本不明显。本文的研究结果为从宏观层面降低股价崩盘风险提供了经验证据,为维护我国股市稳定发展,推进国家治理体系建设提供了政策启示。     

管理者过度自信与企业风险承担

本文检验管理者过度自信是否影响企业的风险承担,以及风险承担的经济后果。我们以沪深A股上市公司2001～2010年的数据作为样本,研究结果发现,管理者过度自信与企业风险承担水平显著正相关。对风险承担经济后果的检验发现,更高的风险承担水平有利于提高企业的资本配置效率和企业价值。以上研究结论意味着,管理者过度自信在企业投资决策中的作用并不完全是消极的。同时,我们也为风险承担能促进经济的持续增长提供了微观层面的证据。本文丰富和拓展了管理者过度自信和企业风险承担的相关研究,对企业的管理者聘任决策以及对企业应重视风险性项目的投资都有一定的现实启示意义。     

官员晋升压力会增加国有企业股价崩盘风险吗？

以2007-2016年我国A股国有上市公司为样本,考察官员晋升压力对国有企业股价崩盘风险的影响。研究发现：官员晋升压力加剧了国有企业的股价崩盘风险,尤其是在政府干预程度较大的地区;进一步作用机制检验显示,官员晋升压力是通过国有企业管理层隐藏负面消息、增加过度投资以及降低环境治理水平而加剧股价崩盘风险的。本文的研究丰富了股价崩盘风险影响因素的理论成果,进一步揭示了官员晋升压力对微观企业的干预作用,并为地方官员晋升考核机制的完善提供了政策启示。     

我国股价崩盘风险文献述评

近年来,随着股市大起大落,以及2018年中美贸易战的进行,我国股市整体呈现出跌宕起伏的情形,为解决股价崩盘对股市带来的不稳定风险,学者们对股价崩盘风险进行了一系列的研究,因此,在已有文献的基础上,本文通过采用citespace以及文献分析法对股价崩盘风险的影响因素、经济后果相关文献进行了整理,并提出未来可研究方向。     

产业政策、管理者过度自信与企业流动性风险

本文对产业政策影响高管自信及企业流动性风险的机理进行分析,提出赶超产业政策激励的管理者过度自信影响企业流动性风险的理论框架,并选取典型案例企业"熔盛重工"进行理论检验。研究表明,产业政策及其传导机制一旦传递出过度激进甚至错误的政策信号,会使管理者的过度自信持续膨胀,进而加剧其对资源配置的认知偏差,导致企业流动性风险失控。这一结论扩展了管理者过度自信和企业流动性风险成因的研究视角,丰富了产业政策经济后果的研究内容,进一步说明应减少产业政策等政府资源配置手段的运用,发挥市场资源配置的决定作用。     

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.     

The development of the group accounts disclosure system in Japan

The Japanese disclosure system of consolidated statements was introduced in 1977 and extensively revised in 1997. The role of the bureaucracy has been significant in these developments and seems to be part of Japan's closed culture. However, other explanations could also be applied. In particular, although Japanese firms opposed such disclosures on the basis of preparation costs, the Japanese government had to modernize the disclosure system, including consolidation, in order to develop the securities market regardless of an individual company's interests.     

Moments of Compound Mixed Poisson Distributions

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities.     

The designing of corporate accounting law in Japan after the Second World War

After the Second World War, during the neutralization of the controlled economy of wartime Japan, a design for a Corporate Accounting Law was elaborated by the Investigation Committee on the Business Accounting System. The Investigation Committee tried to establish not only new business accounting standards but also a central and independent administrative organ of corporate accounting regulation on the basis of the Corporate Accounting Law. The Corporate Accounting Law was expected to lay the legal foundation of the new corporate accounting regulation regime in Japan. Nevertheless, even though the original design of the fundamental accounting law was never realized, it should be considered the starting point for our understanding of external accounting history in post-war Japan.     

The deliberation around accounting techniques: accounting for depreciation and foreign exchange in an Indian jute company, 1870-1900

This paper examines the way two accounting techniques, namely depreciation and foreign exchange, were deliberated on, between 1870 and 1900, in an Indian jute company whose shareholders resided in the UK. The arena for these deliberations was the conflictual relationship between controlling and non-controlling shareholders as to how best to account for depreciation and foreign exchange especially when the particular accountings affected distributional issues such as the dividend decision. The purpose of this paper is to analyse and explain the processes by which a company's accounting practices emerge and develop as a contest between different interests. Accounting framed the parameters of the deliberations and provided the language of power and dissent. The paper uses a rich archive that includes narrative and accounting material.     

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.     

Pricing Dynamic Insurance Risks Using the Principle of Equivalent Utility

We introduce an expected utility approach to price insurance risks in a dynamic financial market setting. The valuation method is based on comparing the maximal expected utility functions with and without incorporating the insurance product, as in the classical principle of equivalent utility. The pricing mechanism relies heavily on risk preferences and yields two reservation prices - one each for the underwriter and buyer of the contract. The framework is rather general and applies to a number of applications that we extensively analyze.
