中国上市公司信息披露影响因素的实证研究——基于长江三角洲地区上市公司的经验证据

本文基于我国长江三角洲地区200多家上市公司信息披露的经验证据,运用计量分析的方法对影响我国上市公司信息披露的主要内在因素进行了实证研究。研究结果表明:(1)我国上市公司法定性信息披露相对较好,但是自愿性信息披露尤其是战略性信息披露的现状十分令人担忧。(2)上市公司规模对信息披露的影响显著,公司规模越大其信息披露的质量指数越高。(3)上市公司股权结构对信息披露的影响显著,但与经济发达国家或地区上市公司股权结构对信息披露的影响相比显现出不尽相同的特点。其中,国家股集中度对其财务性和战略性信息披露的影响是正向的,而法人股集中度对其财务性和战略性信息披露的影响是负向的。(4)上市公司资本结构和盈利能力对其信息披露的影响显著。其中,资本结构对信息披露的影响是负向的,而盈利能力对信息披露的影响是正向的。     

基于GONE理论的LK公司舞弊动因分析与审计风险防范

继浑水发布做空报告后,LK公司于2020年4月自曝2019年年度审计期间发现相关业务数据巨额造假,引起社会广泛关注.企业战略,尤其是商业模式,已经成为管理层产生财务报表层次重大错报风险的重要诱因.文章以GONE理论作为工具来识别和预判财务舞弊的倾向和风险,解释了企业管理层进行财务舞弊的动因.做空机构基于企业战略层面的潜在风险,有针对性地采取手段并取得了有力证据.注册会计师行业应思考如何发挥职业判断在防范审计风险中的作用,尤其要克服认知偏差对保持职业怀疑的影响,同时应借鉴并改进审计程序,以有效降低审计风险.     

Are gold,USD, and Bitcoin hedge or safe haven against stock? The implication for risk management

This study investigates whether gold, USD, and Bitcoin are hedge and safe haven assets against stock and if they are useful in diversifying downside risk for international stock markets. We propose a combined GO-GARCH-EVT-copula approach to examine the hedge and safe haven properties of gold, USD, and Bitcoin. We then examine the attractiveness of these assets in reducing stock portfolio risk by using downside risk measures estimated by the proposed approach and other competing models. We also evaluate the relative performance of the proposed model in reducing downside risk with the competing models. The findings of the study indicate that the USD is the most valuable hedge and safe haven asset closely followed by gold, while Bitcoin is the least valuable. It is also observed that the proposed combined approach performs best in reducing the portfolio downside risk. The findings of this study are of significance for portfolio managers and individual investors who wish to protect the portfolio value during market turmoil.     

Are we nice(r) to nice(r) people?—An experimental analysis

We experimentally investigate whether individuals can reliably detect cooperators (the nice(r) people) in an anonymous decision environment involving “connected games.” Participants can condition their choices in an asymmetric prisoners’ dilemma and a trust game on past individual (their partner’s donation share to a self-selected charity) and social (whether their partner belongs to a group with high or low average donations) information. Thus, the two measures of niceness are the individual donation share in the donation task, and the cooperativeness of one’s choice in the two games. We find that high donors achieve a higher-than-average expected payoff by cooperating predominantly with other high donors. Group affiliation proved to be irrelevant.

国外农村劳动力迁移理论的演变与发展

根据对农村劳动力迁移决策的不同解释,把国外有关劳动力迁移的主要文献分为三类:传统的劳动力迁移理论(包括刘易斯模型、拉尼斯-费景汉模型、托达罗模型)、人力资本劳动力迁移理论和新劳动力迁移理论.目前国内研究劳动力迁移的文献主要以传统劳动力迁移理论和人力资本劳动力迁移理论为研究基础,而对新劳动力迁移理论的借鉴和应用还比较罕见,因此值得我们学习和研究.     

美国金融业对外直接投资流向的实证分析

美国1995年～2000年金融业对外直接投资流向分布极不均衡,对投资流向分布进行统计分析发现,非金融领域直接投资、1994年金融业对外直接投资存量、双边贸易量、东道国经济金融发展水平是金融业对外直接投资的主要决定因素,证明了邓宁国际生产折衷主义理论对金融业对外直接投资的解释力。据此简要分析美国对中国金融领域直接投资现状,并分析了今后发展趋势。     

Teams, Firms and the Evolution of Profit Seeking Behavior

Even as advances in information theory over the last quarter century have cast increasing doubt on the proposition that firms successfully maximize profits, the objective of profit maximization continues to be an axiomatic feature of the neoclassical theory of the firm. This paper attempts to improve our understanding firms by treating the objective function as an open question. Specifically, an ontogenetic thought experiment is undertaken to address the question of what differentiates production teams from firms by asking why team members would sell their control rights to a principal, thereby transforming the team into a firm. What results is an account of the emergence of the objective of profit seeking. Profit seeking emerges endogenously as a more fit alternative than the objective of value maximization, which is less capable of coping with uncertainty through purposive adaptation.     

Directional duality theory Directional duality theory

In this paper we introduce a complete duality theory based on directional distance functions. This duality theory parallels the duality theory based on radial distance functions in Färe and Primont (1995).     

汇率决定理论的新近发展:文献综述

传统汇率决定理论对于现实经济中汇率实际变动情况的解释能力十分低下.20世纪80年代以来,学术界不断寻求突破,以期为汇率如何决定这一基本命题提供更为合理的解释.在这一过程中,不断有新的文献出现,从不同的方面对传统的汇率理论进行补充、发展和替代.鉴于此,本文试图对汇率决定理论的新近发展进行梳理和介绍,借以为国内经济学界研究汇率决定问题提供一个理论参考.
