Industry policy,investor sentiment,and cross-industry capital flow: Evidence from Chinese listed companies’ cross-industry M&As

This study investigates how the government’s industry policies affect investor sentiment, and whether the influenced investor sentiment guides corporate capital flow in the real economy. By examining a sample of cross-industry mergers and acquisitions (M&As) of Chinese listed companies, we find that industry policies promulgated by the government have a significant asymmetric influence on investor sentiment. Furthermore, investor sentiment under the exogenous shock of industry policies has a significant real effect on companies’ cross-industry M&A behavior, generating cross-industry capital flow. Additional analyses reveal that this effect arises because the acquirer depends on equity financing and has incentive to cater to investor sentiment. Our findings help clarify the effect of public policies on the stock market, theoretically, from the company’s micro-level perspective, as well as the mechanism by which stock market volatility transmits to the real economy.     

Investor Behavior and the Benefits of Direct Stock Ownership

Using an experiment to rule out reverse causality, we examine whether a small investment in a company's stock leads investors to purchase more of the company's products and adopt other views and preferences that benefit the company. We preregister our research methods, hypotheses, and supplemental analyses via the Journal of Accounting Research’s registration‐based editorial process. We find little evidence consistent with these hypotheses for the average investor in our sample using our planned univariate hypothesis tests, and planned Bayesian parameter estimation shows substantial downward belief revision for more optimistic ex ante expectations of the treatment effects. In planned supplemental analyses, however, we do find that the effects of ownership on product purchase behavior and on regulatory preferences are intuitively stronger for certain subgroups of investors—namely, for investors who are most likely to purchase the types of products offered by the company and for investors who are most likely to vote on political matters. The results contribute to our understanding of the benefits of direct stock ownership and are informative to public company managers and directors.     

CULTURE,CORPORATE GOVERNANCE,AND DIVIDEND POLICY: INTERNATIONAL EVIDENCE

We find that Hofstede's cultural dimensions—uncertainty avoidance, masculinity, and long‐term orientation—remain significant in the determination of firms’ dividend policies, even after controlling for corporate governance. We also show that this association varies with the strength of corporate governance, measured by the degree of investor protection. Hence, national culture and investor protection independently affect firms’ dividend payouts but also interact with each other, such that strong investor protection induces higher dividend payouts in high uncertainty avoiding and/or highly masculine cultures. Our results provide strong evidence that cultural differences matter and offer additional power in explaining variations in dividend policies.

What's in a “China” Name? A Test of Investor Attention Hypothesis

We study whether a firm's name affects investor attention and firm valuation. Some Chinese firms listed on US stock exchanges have the word “China” included in their company names (“China‐name stocks”), while others do not (“non‐China‐name stocks”). During the 2007 China stock market boom, we find that China‐name stocks significantly outperform non‐China‐name stocks. This is not due to differences in firm characteristics, risk, or liquidity. The “China‐name effect” is largely consistent with the investor attention hypothesis that price pressure caused by increased investor attention on China‐name stocks during the boom period drives up China‐name stocks more than non‐China‐name stocks.     

Have IFRS Affected Earnings Management in the European Union?

There has recently been considerable discussion of those features of IFRS that are likely to help improve financial reporting in the European Union. However, certain issues may also have a negative impact on the quality of information. This paper focuses on the effect of IFRS on earnings management. Its main purpose is to examine whether the adoption of IFRS in the European Union has increased or decreased the scope for discretionary accounting practices by comparing discretionary accruals in the periods preceding and immediately after the regulatory change. Another objective is to determine which firms' features and country factors may explain the accounting discretion observed before and after IFRS. We consider a sample of non-financial firms listed on 11 EU stock markets. The results obtained show that earnings management has intensified since the adoption of IFRS in Europe, as discretionary accruals have increased in the period following implementation. The variables explaining accounting discretion are the same before and after IFRS (business size, leverage, investor protection and legal enforcement). These results suggest that variations in earnings management might be due to some room for manipulation under international standards when compared with local standards.     

Investor relations,reputational bonding,and corporate governance: The case of Royal Ahold

Royal Ahold (Koninklijke Ahold NV) was one of the major success stories in the 1990s and is one of the major failures, suffering a complete meltdown, in 2003. We investigate the strategy, investor relations, accounting transparency and corporate governance of Ahold; these elements jointly drive the firm’s performance over the past decade. Investor relations and its implications are an important but under researched aspect of the market’s belief formation process. For Ahold, investor relations is an important component of reputational bonding [Siegel, J., 2005. Can foreign firms bond themselves effectively by renting US securities laws? Journal of Financial Economics 75, 319–359]. Our clinical study documents investor relations’ influence on investor expectations. We then provide an in-depth analysis of the strategy, accounting transparency and corporate governance that lead to Ahold’s downfall. We provide insights and implications into these relationships that present theory and empirical studies have not fully addressed.     

Volume and skewness in international equity markets

We examine the relation between trading volume and skewness in 11 international stock markets using daily and monthly data from January 1980 to August 2004. We construct single equation and VAR models of the relation between the first three moments of market returns and trading volumes. Our results show hitherto unrecognised channels of influence, and support the investor heterogeneity approach to explaining return asymmetries.     

Liquidity,the Value of the Firm,and Corporate Finance

The theory of corporate finance has been based on the idea that a company's market value is determined mainly by just two variables: the company's expected after‐tax operating cash flows or earnings, and the risk associated with producing them. The authors argue that there is another important factor affecting a company's value: the liquidity of its own securities, debt as well as equity. The paper supports this argument by reviewing the large and growing body of evidence showing that differences—and changes—in liquidity can have major effects on the pricing of corporate stocks and bonds or, equivalently, on investors' required returns for holding them. The authors also suggest that the liquidity of a company's securities can be managed by corporate policies and actions. For those companies whose value is likely to be increased by having more liquid securities—which is by no means true of all companies (mature firms that don't need outside capital may well benefit from having more concentrated ownership and hence less liquidity)—management should consider actions such as reducing leverage and substituting dividends for stock repurchases as well as measures designed to increase the effectiveness of their disclosure and investor relations program and the size of their investor base.     

Relational Investing And Firm Performance

A substantial academic and popular literature argues that the performance of American corporations might improve if American corporations had long‐term outside investors (relational investors) who would hold large stakes, actively monitor management performance, and engage with management in setting corporate policy. Institutional investors can perhaps play this role. We provide the first large‐scale test of the hypothesis that relational investing can affect corporate performance. We consider ownership and performance data for more than 1,500 large U.S. companies over a thirteen‐year period (1983–1995). Our results provide a mixed answer to the question of whether relational investing affects corporate performance. Our data suggest that there was a period in the late 1980s—a period with a uniquely high level of hostile takeover activity—when the presence of a relational investor was associated with higher stock market returns. This cohort of relational investors may have been able to induce corporate restructuring, whose principal effect was to reduce growth rates while improving profitability. But this pattern was not found in the early 1980s or repeated in the early 1990s.     

投资者情绪、经理激励契约与企业投资

本文基于中国上市公司经理激励契约安排的制度背景,把经理激励契约纳入投资者非理性分析框架,就投资者情绪与经理激励契约如何相互作用影响企业投资进行了理论分析,并进行了实证检验。结果发现,高管持股会诱发高管利用投机的股市进行过度投资,而与股价弱相关的货币薪酬没有这种作用,而且经理薪酬的这种作用因企业实际控制人性质不同而有所差异。本研究表明高管持股在企业投资决策中具有负面的公司治理效应。     

Why newly listed firms become acquisition targets

We study the operating, financial, and ownership structure characteristics of newly listed firms which become acquisition targets shortly after their initial public offerings. We examine whether such firms get acquired because of their successful performance or as an alternative to delisting. We find that firms, which do relatively well in terms of operating as well as stock performance and attract institutional investor interest, draw the attention of acquirers. Furthermore, we observe that investments made by newly listed target firms do not destroy shareholder value and have comparable profitability to investments made by newly listed firms which grow by acquisitions. Overall, firms acquired shortly after listing are on a growth trajectory similar to that of surviving firms.     

Rumors in the sky: Corporate rumors and stock price synchronicity

Using hand-collected rumor clarification announcements from Chinese listed firms to identify corporate rumors, we find that rumored firms have lower stock price synchronicity (R²) than do firms without rumors. Channel analyses reveal that rumors reduce stock price synchronicity through elevating investor sentiment rather than stimulating informed trading. Additionally, the negative association between corporate rumors and stock price synchronicity is more evident among firms with more individual investors and higher information opacity. Moreover, corporate rumors are associated with higher analyst forecast errors and forecast dispersion. Overall, our evidence suggests that corporate rumors reduce stock price synchronicity by increasing investor irrationality.     

The contribution of stock repurchases to the value of the firm and cash holdings around the world

Using corporate payout data from 33 economies, this study investigates the contribution of stock repurchases to the value of the firm and cash holdings in different country-level investor protection environments. We find that stock repurchases contribute more to firm value in countries with strong investor protection than in countries with weak investor protection. We also report that dividends contribute approximately 60% more to firm value than repurchases in countries with weak investor protection. Furthermore, as the proportion of repurchases in total payouts increases, the marginal value of cash increases in countries with strong investor protection, whereas it declines in countries with weak investor protection. In a poor investor protection environment, the marginal value of cash for a firm that makes 100% of its payouts via repurchases is 12 cents lower than that for a firm that distributes 100% of its payouts via dividends. Overall, our findings highlight that stock repurchases are less effective than dividends in mitigating agency problems associated with free cash flow in countries with poor investor protection.     

Social media information dissemination and corporate bad news hoarding

This paper investigates the role of social media in mitigating corporate bad news hoarding from a stock price crash risk perspective. Using a sample of public listed firms from 2008–2019, we find that social media (Guba) posts could significantly reduce firms’ stock price crash risks in the Chinese stock market. Furthermore, we find that the information intermediation function and complementary corporate governance function enable Guba to achieve such an effect. In addition, investor attention mediates the relationship between Guba posts and management withholding bad news. Our result still holds after a series of robustness checks, including an RDD approach.     

Does stock market development always improve firm-level financing? Evidence from Tunisia

The question of whether or not increased stock market size allows for improved financing conditions for firms in emerging markets is an important one for policy-making. This paper seeks to investigate this issue by analyzing whether increases in market-level liquidity have indeed trickled down to individual firms over the last decade of stock market development in Tunisia, a fast-growing Mediterranean emerging market. We develop time varying liquidity scores for all firms listed in the Tunisian market over the 1997–2009 period and analyze the extent to which market development, firm-level characteristics and risk exposure affect the magnitude and the distribution of liquidity using a set of fixed effect panel regressions. Our results suggest that massive increases in value traded have created market congestion, thereby increasing the costs of trading, in a context of persistently low efficiency and increased international integration. The main implications of this process are (i) market-level development and international integration are not sufficient conditions to ease access to finance for local firms, (ii) further reforms in the Tunisian market should focus on diversifying corporate ownership and improving the disclosure of information, and (iii) international investors seeking diversification in Tunisia should be aware of a significant illiquidity risk.

对上海证券交易所和香港证券交易所上市的蓝筹公司的网站中与投资者关系有关的条目进行了调查统计分析,提出了用WBIRX指数来衡量上市公司基于网站的投资者关系工作的发展水平。通过对WBIRX指数和调查数据进行分析发现,尽管上交所蓝筹公司在网站投资者关系建设方面取得了长足的进步,但是在总体水平上还与港交所蓝筹公司有一定差距,同网站投资者关系有关的栏目数量、类别和质量都还有待提高。     

Liquidity,the Value of the Firm,and Corporate Finance*

The theory of corporate finance has been based on the idea that a company's market value is determined mainly by just two variables: the company's expected aftertax operating cash flows or earnings, and the risk associated with producing them. The authors argue that there is another important factor affecting a company's value: the liquidity of its own securities, debt as well as equity. The paper supports this argument by reviewing the large and growing body of evidence showing that differences—and, perhaps even more important, sudden changes—in liquidity can have major effects on the pricing of corporate stocks and bonds or, equivalently, on investors' required returns for holding them. The authors also suggest that the liquidity of a company's securities can be managed by corporate policies and actions. For those companies whose value is likely to be increased by having more liquid securities—which is by no means true of all companies (for example, mature firms with little need for outside equity are likely to benefit from having more concentrated ownership and hence less liquidity)—management should consider actions such as reducing leverage and substituting dividends for stock repurchases as well as measures designed to increase the effectiveness of their disclosure and investor relations program and the size of their retail investor base.     

Determinants of Sovereign Wealth Fund Cross‐Border Investments

Using a sample of 1,590 purchases of stock by sovereign wealth funds (SWFs) in listed firms in 78 target countries between 1985 and 2011, we study the country‐level determinants of SWF cross‐border investment. We find that SWFs from countries with high levels of openness and economic development, but with less developed local capital markets, will make more cross‐country transactions, while target countries with higher levels of investor protection and more developed capital markets will attract more SWF investment. Our findings support the investment facilitation hypothesis, suggesting that SWFs act purely or principally as commercial investors facilitating cross‐border corporate investment.
