外资参股中国上市公司的动机与模式分析

基于当前我国外资参股中国上市公司的发展历程与现状,本文分析了外资参股中国上市公司的动机和模式,指出外资参股的根本原因在于资本的逐利性,外资参股的动机主要有经营性动机、战略性动机和投机性动机;外资参股我国上市公司的模式有直接参股模式和间接参股模式。在此基础上,本文从宏观和微观两个层面提出了加强对外资参股我国上市公司管理的政策建议。     

Accounting for financial instruments with characteristics of debt and equity: finding a way forward

Accounting for compound financial instruments, that is those with characteristics of both debt and equity, has challenged accounting standard setters for decades. The principles developed to distinguish liabilities and equity and the application of these principles in IAS 32 have been widely criticised. In 2016–2017, the IASB was engaged in a project to improve IAS 32. Our study presents research that is relevant to the issues faced by standard setters, related to improving the definitions and enhancing presentation and disclosure of liabilities and equity. We discuss studies investigating the effects of the accounting classification requirements on firms’ financing choices and on users’ decision‐making, to examine the question, ‘Does the distinction matter?’ We then explore various approaches that may be pursued by the standard setters to improve accounting in this area and identify areas for future research.     

多元化并购溢价与企业转型

以往研究表明多元化并购源于代理问题、内部市场和生命周期,其绩效一般低于同行业并购。本文利用我国2008年-2014年277个重大资产重组样本发现多元化并购存在8.42%的溢价。机制上,转型到新业务企业(“另起炉灶”型)完全导致了多元化并购溢价,其并购前业绩较差,并购后业绩明显改善,企业转型的力度可以解释多元化溢价。同时,此类并购改善公司业绩的效果在并购后三年依然存在。上述结果说明,多元化并购在短期内帮助业绩较差的已上市企业实现转型,金融市场能部分反映并购后基本面的改善。     

货币政策公告、政策不确定性及股票市场的预公告溢价效应——来自中国市场的证据

中国人民银行周期性发布的货币政策相关公告为市场判断货币政策走向提供重要信息。较于实体经济反馈政策信息具有滞后性,股票市场是否在货币政策公告期内及时对政策消息做出反应,即存在公告效应？股票价格是否体现预期货币政策调整带来的不确定性？本文基于2011-2017年A股市场数据,研究我国股票市场在我国货币政策相关公告发布前后几日这一较短窗口区间内的市场反应。结果表明,股市指数在发布货币供应量指标的公告前几天内会出现显著为正的风险溢价,而在指标发布后溢价并不显著,这一现象我们称之为货币政策相关公告的“预公告溢价效应”。本文发现,预公告溢价的产生并非由于市场提前预期到货币政策的走向,而是来源于投资者预先获得了对政策不确定性的溢价补偿。本文进一步就防范系统性风险、从数量型货币政策工具向价格型转变等问题提出了相关政策建议。     

中国A股市场存在品质溢价吗?

本文从价值投资的核心理念出发,基于盈利性、成长性、安全性、分红能力四个维度构建复合品质指标,并通过分析品质溢价在中国A股市场中的存在性来探讨价值投资的可行性和有效性。实证结果表明:(1)中国A股市场上存在显著为正的品质溢价,且品质溢价在控制其他相关变量后依然稳健存在;(2)高品质股票具有大市值、高成长特征,且品质溢价在大市值、高盈利的分组中更加显著;(3)品质溢价在不同时期下均能稳定存在;(4)中国A股市场上的品质溢价并非源于高风险承担,相反,由正向反馈偏好、博彩偏好、套利限制引起的错误定价有助于解释品质溢价。本文结论佐证了价值投资策略在中国A股市场的可行性和有效性,为培育良好投资理念、抑制过度投机、促进中国股市合理健康发展等提供了经验证据。     

Disagreement and return predictability of stock portfolios

This paper provides evidence that portfolio disagreement measured bottom-up from individual-stock analyst forecast dispersions has a number of asset pricing implications. For the market portfolio, market disagreement mean-reverts and is negatively related to ex post expected market return. Contemporaneously, an increase in market disagreement manifests as a drop in discount rate. For book-to-market sorted portfolios, the value premium is stronger among high disagreement stocks. The underperformance by high disagreement stocks is stronger among growth stocks. Growth stocks are more sensitive to variations in disagreement relative to value stocks. These findings are consistent with asset pricing theory incorporating belief dispersion.     

A theory of equity carve-outs and negative stub values under heterogeneous beliefs

We develop a theory of new-project financing and equity carve-outs under heterogeneous beliefs. In our model, an employee of a firm generates an idea for a new project that can be financed either by issuing equity against the cash flows of the entire firm (“integration”), or by undertaking an equity carve-out of the new project alone (“non-integration”). While the patent underlying the new project is owned by the firm, the employee generating the idea needs to be motivated to exert optimal effort for the project to be successful. The firm's choice between integration and non-integration is driven primarily by heterogeneity in beliefs among outside investors (each of whom has limited wealth to invest in the equity market) and between firm insiders and outsiders: if the marginal outsider financing the new project is more optimistic about the prospects of the project than firm insiders, and this incremental optimism of the marginal outsider over firm insiders is greater regarding new-project cash flows than that about assets-in-place cash flows, then the firm will implement the project under non-integration rather than integration. Two other ingredients driving the firm's financing choice are the cost of motivating the employee to exert optimal effort, and the potential synergies between the new project and assets in place. We derive a number of testable predictions regarding a firm's equilibrium choice between integration and non-integration. We also provide a rationale for the “negative stub values” documented in the equity carve-outs of certain firms (e.g., the carve-out of Palm from 3Com) and develop predictions for the magnitude of these stub values.     

我国企业高管股权激励与研发投资——基于内生性视角的研究

本文以2002—2009年我国上市公司为研究对象,探讨了股权分置改革前后我国企业管理层股权激励对研发投资的影响,并在此基础上检验了管理层股权激励的内生性。研究发现,高管股权激励存在内生性,在控制了内生性之后,股改前股权激励与研发投资之间存在倒U形曲线关系;股改后股权激励对研发投资具有显著的正向影响。本文结果表明应该将研发投资作为股权激励方案的激励条件之一;此外,合理的安排股东与管理层之间的股权配置比例是保证企业有效进行研发投资、提升企业自主创新能力的必要手段。本文的结论深化了我们对股权激励内生性的理解,并为我国企业更好地实施管理层股权激励和企业自主创新战略提供了理论支持和实证证据。     

Global asset prices and FOMC announcements

This paper analyzes the impact of U.S. monetary policy announcement surprises on foreign equity indexes, short- and long-term interest rates, and exchange rates in 49 countries. We use two proxies for monetary policy surprises: the surprise change to the current target federal funds rate (target surprise) and the revision to the expected path of future monetary policy (path surprise). We find that different asset classes respond to different components of the monetary policy surprises. Global equity indexes respond mainly to the target surprise; exchange rates and long-term interest rates respond mainly to the path surprise; and short-term interest rates respond to both surprises. On average, a hypothetical surprise 25-basis-point cut in the federal funds target rate is associated with about a 1 percent increase in foreign equity indexes and a 5 basis point decline in foreign short-term interest rates. A surprise 25-basis-point downward revision in the expected path of future policy is associated with about a ½ percent decline in the exchange value of the dollar against foreign currencies and 5 and 8 basis point declines in short- and long-term interest rates, respectively. We also find that asset prices’ responses to FOMC announcements vary greatly across countries, and that these cross-country variations in the response are related to a country’s exchange rate regime. Equity indexes and interest rates in countries with a less flexible exchange rate regime respond more to U.S. monetary policy surprises. In addition, the cross-country variation in the equity market response is strongly related to the percentage of each country’s equity market capitalization owned by U.S. investors. This result suggests that investors’ asset holdings may play a role in transmitting monetary policy surprises across countries.     

Long-run risk in durable consumption

Durable consumption growth is persistent and predicted by the price-dividend ratio. This provides strong and direct evidence for the existence of a highly persistent expected component. Durable consumption growth is left-skewed and exhibits time-varying volatility. I model durable consumption growth as containing a persistent expected component and driven by counter-cyclical volatility, nondurable consumption as a random walk, and dividend growth as exposed to the expected component of durable consumption growth. Together with nonseparable Epstein-Zin preferences, the model demonstrates that long-run risk in durable consumption can explain major asset market phenomena. The model also generates an upward-sloping real term structure.
