股权分置改革的盈余质量效应

股权分置改革后,股价直接决定了股东的财富,持有大量非流通股的控股股东有动机操纵盈余以最大化自身的利益。国有股权转让的限制,导致国有控股股东盈余操纵动机弱于其他股东。本文研究了股权分置改革对国有控股公司和非国有控股公司盈余质量的不同影响。研究结果表明,股权分置改革后,非国有上市公司向上盈余管理程度显著提高,盈余持续性显著降低;而国有上市公司的盈余管理程度和盈余持续性都没有显著变化。本文检验了股权分置改革的成效,研究结论可为投资者的投资行为提供决策支持。     

Stock liquidity and corporate tax avoidance

We show that firms with higher stock liquidity engage less in extreme (i.e., overly aggressive or overly conservative) tax avoidance. The effect of stock liquidity on tax avoidance is economically meaningful and robust across alternative measures of tax avoidance and stock liquidity. The findings also hold after controlling for potential endogenous effects. We further document that the effect of stock liquidity on tax avoidance is amplified for firms with high proportions of activist shareholders and attenuated for firms with high levels of stock price informativeness. Overall, our findings suggest that stock liquidity mitigates extreme tax avoidance by enhancing shareholders’ monitoring over firm management.

     

The effect of the split share structure reform on working capital management of Chinese companies

Before the introduction of the Split Share Structure Reform (SSSR) of 2005, a dual stock system characterized Chinese-listed firms. The states owned non-tradable shares and private owners held tradable shares. The dual system generated agency problems because state owners enjoyed all the rights reserved for tradable shares but escaped the stock market risk faced by non-state shareholders. Because executives of state-owned enterprises (SOEs) received rewards based on the book value of assets rather than the market price of shares, they had no incentive to maximize the share price. The SSSR led to the conversion of non-tradable shares to tradable shares, with two major implications: (1) the interests of government and private owners are now more closely aligned and (2) government agents of SOEs are now rewarded and punished based on a firm's market performance. Thus, the expectation is that government agents turn their attention to improving a firm's market performance rather than its book value during the post-reform era. We examine the impact of the SSSR on Chinese firms' investments in working capital. Based on 511 manufacturing firms between 2003 and 2011, we find that the SSSR is associated with significant reductions in working capital investments during the post-reform period. The reduced investment in working capital is associated with improved market performance of these firms.     

Saving or tunnelling: value effects of tax avoidance in Chinese listed local government-controlled firms

This paper investigates the value effect of tax avoidance and its underlying mechanisms among Chinese listed local government-controlled (LG) firms. We show that tax avoidance does not promote firm value in LG firms with government ownership smaller than 40 percent and the above negative tunnelling effect is more pronounced when the control rights are concentrated in the local government and weaker when other large shareholders can act as a countervailing force. Finally, we observe a positive relation between tax avoidance and related-party transactions as well as overinvestment, again indicating a tunnelling effect in LG firms with government ownership smaller than 40 percent.     

Corporate Social Responsibility,Tax Aggressiveness,and Firm Market Value

This paper examines the relationship of corporate social responsibility (CSR), tax aggressiveness, and firm market value. An economic model has been developed to show that profit‐maximization firms are willing to incur additional costs in CSR, such as paying more taxes, as long as they can differentiate their products from non‐CSR firms, and that socially conscious consumers will buy products from CSR firms at prices higher than those of non‐CSR firms. The empirical study in this paper indicates that the higher the CSR ranking of a firm, the less likely a firm is to engage in tax aggressiveness. It also indicates that a reputation of higher CSR will enhance firm market value. Using Canadian companies listed in the S&P/TSX 60 index, I find that both firms’ five‐year effective tax rates and annual effective tax rates are positively associated with their overall CSR scores as well as with their social scores. Firms’ five‐year effective tax rates are also positively associated with their governance index. I also find that firms’ overall CSR ranking and governance scores are positively associated with their market value.     

Split Share Structure Reform,corporate governance,and the foreign share discount puzzle in China

We examine the impact of the Split Share Structure Reform on the well-known foreign share discount puzzle in China. Existing literature confirms that foreign investors are more concerned about insider expropriation because of their information disadvantage relative to domestic investors. The split share structure of the ownership of Chinese listed firms created a conflict of interests between state and private shareholders. Since, before the reform, state shareholders held restricted shares that denied them any wealth effect from share price movements, they had a limited incentive to work with private shareholders to ensure that managers maximized the stock market value of the firm. By abolishing the trading restrictions for state shareholders, this reform has increased the incentive alignment between state and private shareholders, encouraging them to monitor managers. If foreign investors’ concerns over the corporate governance implications of the split share structure at least partly contributed to their discounting of Chinese listed firms, then this discount should be reduced following the reform. Indeed, our evidence confirms this prediction, especially among Chinese listed firms with more state ownership or restricted shares. Our findings imply that this significant institutional reform of the Chinese stock market has benefitted minority investors.     

Agency costs and tax planning when the government is a major Shareholder

In state owned enterprises (SOEs), taxes are a dividend to the controlling shareholder, the state, but a cost to other shareholders. We examine publicly traded firms in China and find significantly lower tax avoidance by SOEs relative to non-SOEs. The differences are pronounced for locally versus centrally-owned SOEs and during the year of SOE term performance evaluations. We link our results to managerial incentives through promotion tests, finding that higher SOE tax rates are associated with higher promotion frequencies of SOE managers. Our results suggest managerial incentives and tax reporting are conditional on the ownership structure of the firm.     

Earnings Management in Business Groups: Tax Incentives or Expropriation Concealment?

This study provides evidence that Belgian firms affiliated to a business group (holding) manage their earnings more than stand-alone firms. Earnings management is especially more prevalent in fully owned group firms compared to group firms with minority shareholders. This evidence is consistent with the hypothesis that controlling shareholders face fewer constraints to manage earnings if opportunistic earnings management cannot adversely affect the value of minority shareholders and is inconsistent with the claim that group firms would engage in earnings management to hide controlling shareholders' self-serving transactions. On the incentive part, we find that group firms strategically manage earnings in response to tax incentives. More specifically, we show that signed discretionary accruals of group firms depend significantly more on the marginal tax rate status of the firm as compared to independent firms. Finally, we document that earnings management is particularly facilitated through intra-group transactions.     

Share pledges,tone of earnings communication conferences,and market reaction: evidence from China

We investigate how share pledging affects firms’ disclosures and influences investors in Chinese stock market. The tone of firm disclosures when there are shares pledged by controlling shareholders is more positive than that of firms without them. Considering tone inflation motivation and ability simultaneously, we find share pledge risk has an inverted U‐shaped relation with tone. Investors react positively to tone in short‐run windows, and firms with controlling shareholders’ pledges have higher stock returns for earnings communication conferences. We identify an inverted U‐shaped link between margin distance of controlling shareholders and stock returns for earnings communication conferences.     

Partial Privatization and Firm Performance

Most privatization programs begin with a period of partial privatization in which only non‐controlling shares of firms are sold on the stock market. Since management control is not transferred to private owners it is widely contended that partial privatization has little impact. This perspective ignores the role that the stock market can play in monitoring and rewarding managerial performance even when the government remains the controlling owner. Using data on Indian state‐owned enterprises we find that partial privatization has a positive impact on profitability, productivity, and investment.     

Do share prices matter?

This paper examines whether the cross sectional variation in Australian share prices is partially explained by measures of firm size and ownership characteristics in a manner that is consistent with firms behaving in accordance with Merton's (1987) model of capital market equilibrium with incomplete information. Based on a sample of firms whose shares were traded on the ASX during 1995, we show that firms largely owned by less wealthy shareholders tend to have low stock prices, although this relation is not linear. In addition, larger, better–known, firms tend to have higher stock prices. These findings are consistent with prior evidence from US markets, and suggest the existence of a shareholder clientele effect in Australia that is related to the share price of the underlying firm.     

Dividend payouts and catering to demands: Evidence from a dividend tax reform

Utilizing the 2012 dividend tax reform in China, this paper examines how firms make dividend payout decisions that cater to the controlling shareholders' demand, especially when controlling shareholders and outside minority shareholders have different dividend preferences. We find that firms increase dividend payouts when controlling shareholders demand higher dividends after the dividend tax reform. In particular, firms pay higher dividends when facing increased demand from controlling shareholders than when the demand is from minority investors. In addition, we find that firms that increase dividend payments due to the controlling shareholders' demand subsequently have more debt financing and poorer firm performance, suggesting that catering to the demands from controlling shareholders is subject to the Type II agency problem.     

Are family firms more tax aggressive than non-family firms?

Taxes represent a significant cost to the firm and shareholders, and it is generally expected that shareholders prefer tax aggressiveness. However, this argument ignores potential non-tax costs that can accompany tax aggressiveness, especially those arising from agency problems. Firms owned/run by founding family members are characterized by a unique agency conflict between dominant and small shareholders. Using multiple measures to capture tax aggressiveness and founding family presence, we find that family firms are less tax aggressive than their non-family counterparts, ceteris paribus. This result suggests that family owners are willing to forgo tax benefits to avoid the non-tax cost of a potential price discount, which can arise from minority shareholders’ concern with family rent-seeking masked by tax avoidance activities [Desai and Dharmapala, 2006. Corporate tax avoidance and high-powered incentives. Journal of Financial Economics 79, 145–179]. Our result is also consistent with family owners being more concerned with the potential penalty and reputation damage from an IRS audit than non-family firms. We obtain similar inferences when using a small sample of tax shelter cases.     

Shareholding structure and corporate performance of partially privatized firms: Evidence from listed Chinese companies

Equity ownership in a listed Chinese firm can have as many as five different classes: state-owned shares, legal-person (LP) shares, tradable A-shares, employee shares, and shares only available to foreign investors, a phenomenon that is unique to the Chinese equity market. In this paper, we investigate whether and how the corporate performance of listed Chinese firms is affected by their shareholding structure. The sample consists of all firms listed in the Shanghai Stock Exchange (SHSE) from 1991 to 1996. It is found that firm performance is positively related to the proportion of LP shares but negatively related to the proportion of shares owned by the state. Additional analyses indicate that firm performance increases with the degree of relative dominance of LP shares over state shares. Moreover, for the subsample of firms that do not have both state and LP shares, the return on equity (ROE) of firms with LP shares but no state shares is higher than that of firms with state shares but no LP shares by 3.84%, and this difference is statistically significant. On the other hand, there is little evidence in support of a positive correlation between corporate performance and the proportion of tradable shares owned by either domestic or foreign investors. These findings suggest that the ownership structure composition and relative dominance by various classes of shareholders can affect the performance of state-owned enterprise (SOE)-transformed and listed firms.     

媒体公关、投资者情绪与证券发行定价

本文研究了拟上市公司通过专门针对媒体的公关活动影响其证券发行定价的内在机制。结果发现:公司可以通过投入媒体公关费用来增加媒体对于该公司的新闻报道量,这些报道在性质上属于正面的广告宣传,而正面新闻能够显著提高投资者对该公司的关注程度和乐观情绪;乐观情绪越强,则参与证券发行的投资者人数越多,需求量越大,进而导致证券发行价格的上调幅度越大。但是在长期内,当证券交易价格逐渐回归于实际价值时,发行前关注度越高的证券,其长期回报率越低。本文的研究意味着新闻媒体在证券发行中的宣传推介功能与其公司外部治理人的身份存在冲突。     

企业创新效率研究——来自股权质押的影响

本文结合我国实施创新驱动发展战略及股权质押频繁的现实背景,利用2006—2015年A股上市公司的数据,探讨控股股东的股权质押行为是否以及如何对企业的创新效率产生影响。研究表明,控股股东的股权质押行为会显著降低企业的创新效率。进一步地研究发现:(1)当第二类代理问题越严重,或质押风险越大时,控股股东股权质押行为抑制企业创新效率的作用越明显,表明控股股东股权质押伴随的掏空效应及短视效应,是导致二者负向关系的重要原因;(2)掏空效应和短视效应在影响控股股东股权质押与企业创新效率的关系上存在显著的替代效应;(3)研发投入强度下降时,控股股东股权质押对企业创新效率产生的负面效应更强。本文的研究不仅丰富了企业创新效率影响因素及控股股东股权质押经济后果的相关文献,对于规范控股股东股权质押行为,提高企业创新能力,实现创新驱动发展战略,也具有重要的启示意义。     

Controlling shareholder,expropriations and firm's leverage decision: Evidence from Chinese Non-tradable share reform

This paper examines the effect of excess control rights on the leverage decisions made by Chinese non-SOEs before and after the Non-tradable share reform (NTS reform). We find that firms with excess control rights have more excess leverage and their controlling shareholders use the resources for tunneling rather than investing in positive NPV projects. We also find that excess leverage in firms with excess control rights decreases and the market reaction to announcements of related party transactions are more positive after NTS reform. This confirms that tunneling by the controlling shareholders actually reduced. We argue that in emerging markets where legal protection for creditors and shareholders is weak, controlling shareholders borrow excess debt to tunnel through inter-corporate loans and related party transactions. Furthermore the privatization of these economies can reduce the controlling shareholders' tunneling activities and associated excess leverage which destroys firm value.     

股权质押、风险管理与大股东增持

基于2004-2016年A股上市公司样本,本文发现,股权质押会影响上市公司大股东的增持行为,而质押风险管理是股权质押影响大股东增持的潜在渠道。相较于未面临质押预警压力的大股东,面临质押预警压力的大股东更有可能去增持;此外,相较于国有企业,民营企业的大股东在面临质押预警压力时更有可能去增持。在经济后果方面,对于同样面临质押预警压力的大股东而言,选择增持会让上市公司股价在之后有更好的表现。本文认为,除了传统的财务动机等之外,缓解自身质押风险是上市公司大股东增持的另一动机;而除了盈余管理、税收规避等管理质押风险的事前措施外,增持是上市公司大股东管理质押风险的另一有效手段。     

Stock‐Based Compensation in a Concentrated Ownership Setting: An Empirical Investigation

Stock‐based compensation has been viewed as an important mechanism for tying managers’ wealth to firm performance, and thus alleviating the agency conflict between the shareholders and the managers when ownership is diffused. However, in a concentrated ownership structure, controlling owners are usually the management of the firm; they can engage in self‐dealing activities to the detriment of minority shareholders’ interests. Yet, outside investors may anticipate the problem and discount the share price for the entrenchment behaviors they observe. In this study, we investigate how controlling owners trade off the benefits and the costs of using stock‐based compensation. Based on a sample of Taiwanese firms, our evidence shows that stock‐based compensation is negatively related to the agency problem embedded in a concentrated ownership structure. This relationship is evident among firms with more frequent equity offerings. Overall, our empirical evidence suggests that controlling owners consider the negative price effects of stock‐based compensation and trade off these costs with the benefits of expropriating minority shareholders’ interests, particularly when firms seek more external equity capital. Our results hold after controlling for selection bias and share collateral by controlling owners.     

When bank loans are bad news: Evidence from market reactions to loan announcements under the risk of expropriation

In this paper we investigate whether inefficient bank loans can reduce the value of borrowing firms when expropriation of the stock of minority shareholders by controlling shareholders is a major concern. Using data from Chinese banks, we find that bank loan announcements generate significantly negative abnormal returns for the borrowing firms. In line with this expropriation view, negative stock price reactions following bank loan announcements are concentrated in firms that are perceived to be more vulnerable to expropriation by controlling shareholders. Finally, we find evidence that a negative relationship between market reactions and firm vulnerability to expropriation exists only when firms borrow from the least efficient banks.
