Stock market liquidity and information asymmetry around voluntary earnings disclosures

Purpose – The purpose of this paper is to examine whether non‐mandated earnings disclosures include value‐relevant information and affect information asymmetry and stock market liquidity.Design/methodology/approach – The event study methodology explores the informational content of good, bad and neutral voluntary earnings disclosures. The OLS panel regression framework is, then, used to analyze information asymmetry and stock market liquidity subsequent to both categories of voluntary earnings disclosures (i.e. earnings forecasts and quarterly earnings disclosures).Findings – Empirical tests show that voluntary earnings disclosures include material information and that bad news is released in an untimely fashion leading to information leakage in the pre‐announcement period. The results also indicate that quarterly earnings enhance stock market liquidity by shrinking bid‐ask spreads. However, earnings forecasts exacerbate information asymmetry before and after the announcement date. This result confirms th...

Institutional Investors, information asymmetry and stock market liquidity in France

Purpose - – The purpose of this paper is to examine the effect of institutional investors’ ownership and type on information asymmetry and stock market liquidity in France. Design/methodology/approach - – The sample includes 162 French-listed firms from 2007 to 2009. The methodology relies on linear regressions using the method of ordinary least square. Before examining the interaction between liquidity and institutional investors, the authors check for the existence of the endogeneity problem by applying the Durbin-Wu-Hausman test of Davidson and MacKinnon (1993). The results of the endogeneity test show that institutional investors’ ownership and stock liquidity are endogenous. A simultaneous equation model using the double least square method is then tested to address this problem. Findings - – The findings show that the proportion of institutional investors has a positive and significant effect on stock-market liquidity, which confirms the signal theory and trading hypothesis. These investors perform high trading activity which favorably affects market liquidity. The results also show that pension funds improve stock liquidity. This result suggests that pension funds manage huge assets decreasing transaction costs and improving liquidity. They display a positive signal to the market about more transparency and a low level of informational asymmetry. Practical implications - – These results highlight the institutional investors’ role in defining the level of liquidity on the French market. The findings also stress the relevance of developing institutional investors’ demand for the Paris market in order to better assess firm value, protect minority ownership and improve market liquidity. Originality/value - – In the French institutional setting, institutional investors act as a control device since minority shareholder interests are less protected than in Anglo-American counterparts. This result highlights the significant role of institutional investors in corporate governance structures and on financial markets. Their presence is a guarantee for minority interest protection and for more liquid stocks.

Does family ownership reduce corporate tax avoidance? The moderating effect of audit quality

Purpose The purpose of this paper is to shed light on the effect of family ownership on corporate tax avoidance. It also investigates whether audit quality affects tax avoidance practices by family firms. Design/methodology/approach Based on a sample of 55 Tunisian listed companies from 2008 to 2013, the authors use GLS regression models estimated with robust standard errors, clustered at the firm level. Findings The results show that family ownership is positively associated with corporate tax avoidance practices, suggesting that families expropriate minority interests by extracting rents from tax-saving positions. These practices are less prominent after the 2011 Tunisian revolution, suggesting that the pressure from governments and non-governmental organizations against corruption and unethical behavior has increased after the revolution. However, the findings show that audit quality curbs the incentives of family firms to engage in aggressive tax positions, supporting the moderating effect of audit quality on the relation between family ownership and tax avoidance. Research limitations/implications These findings suggest that Tunisian family firms are likely to expropriate minority interests by extracting rents from tax-saving positions. However, in presence of high-quality audit, the relation turns negative, suggesting that external audit quality is an efficient corporate governance device that is likely to monitor family corporate decisions. Originality/value This paper extends previous research by investigating the moderating effect of external audit quality on the relation between tax avoidance and family ownership. It also examines tax avoidance by family firms in a unique setting: Tunisia, a transitioning economy subsequently to the 2011 revolution, where investors’ rights are weakly protected and the financial market is not well-developed as in more developed countries.
