An Examination of the Naïve‐Investor Hypothesis in Accruals Mispricing in Tunisian Firms

This study extends previous studies on accrual anomaly to investigate the emerging market's mispricing of accruals. Using Mishkin (1983) test, hedge portfolio test and Fama and MacBeth (1973) regression, we test whether the Tunisian Stock Exchange price rationally reflects the 1‐year ahead earnings implications of its earnings components. We find that earnings and their cash flow and accrual components are not rationally priced by the market. Additionally, this paper examines the role of sophistication investors in the pricing of earnings and their components. Our results show that accruals for firms with higher level of institutional ownership are not mispriced, while accruals for firms with lower institutional ownership are overpriced significantly by the market.     

On the predictive power of the surplus consumption ratio

This paper shows that the surplus consumption ratio, specified by Campbell and Cochrane [1999. Journal of Political Economy 107, 205–251], is a good predictor of excess returns at long horizons. We also provide empirical evidence that this variable captures a component of expected returns, not explained by the proxies for the consumption to wealth ratio, cay and cdy, proposed by Lettau and Ludvigson [2001a. Journal of Finance 56, 815–849; 2001b. Journal of Political Economy 109, 1238–1286; 2005. Journal of Financial Economics 76, 583–626]. Moreover, used as a conditioning information for the Consumption based Asset Pricing Model (C)CAPM, the resulting linear model helps to explain for the variation in average returns across the Fama–French (25) portfolios sorted by size and book-to-market characteristics.     

Internal Control Weaknesses,Family Ownership and the Cost of Debt: Evidence from the Tunisian Stock Exchange

ABSTRACT

This study investigates the effect of internal control weaknesses (ICW) and family ownership on the cost of debt in the Tunisian setting. We document that ICW and family ownership are positively associated with the cost of debt. When testing for the moderating effect of family ownership on the association between ICW and the cost of debt, we document that the positive effect of ICW on the cost of debt is more pronounced under high family ownership in the Tunisian setting. Furthermore, the positive and significant association between ICW and the cost of debt is more prevailing for firms audited by non-Big 4 auditors and industrial companies. These findings may have policy implications for Tunisian policymakers with respect to the establishment of internal control standards.     

Hurst exponent behavior and assessment of the MENA stock markets efficiency

In this paper, we test the evolving efficiency of MENA stock markets. Our empirical approach is founded on the behavior of the Hurst exponent over time. We computed the Hurst exponent using a rolling sample with a time window of 4 years. The empirical investigation has been conducted on the major Middle East and North African stock markets. The sample data covers in daily frequency the period (January 1997 to December 2007). Our empirical results show that all MENA stock returns exhibit long-range memory and certain markets are becoming more efficient. Ranking MENA stock markets by efficiency with our measures of long-range dependence have shown that Israel's, Turkey's and Egypt's markets are the less inefficient markets in this region. Furthermore, we have founded evidence of statistically significant rank correlation between the measure of long-range dependence and average trading costs, market capitalization and anti-self-dealing index, which suggests that these variables play a role in explaining these differences in the stage of inefficiency.     

R&D investment and future firm performance: The role of managerial overconfidence and government ownership

We investigate the relationship among managerial overconfidence (MO), government ownership, and research and development (R&D) investment using data from Vietnamese public companies for the period 2007–2016. We also investigate how R&D investment, given MO and government ownership, affect future firm performance. Our results indicate that MO and government ownership are positively related to R&D investment. Conceptually, this study investigates novel factors affecting of R&D investment and their role in improving firm performance. Overall, this study emphasizes the importance of R&D investment in the corporate world, improving firm performance and, ultimately, economic prosperity.     

Mutual fund performance: The decision quality and capital magnet efficiencies

This study employs a two-stage network data envelopment analysis model to analyze the decision quality and capital magnet efficiencies of 155 mutual funds in Taiwan during the period 2007–2016. The empirical results show that fund managers improved their decision quality; however, their capital magnet efficiency declined. This study also found 10 mutual funds performing in decision quality and capital magnet efficiencies, from which practical suggestions are provided to investors. Finally, this study constructs a market competition matrix to help fund managers (and investors) improve their operating and portfolio performance, plus resource allocation.     

Ownership structure and debt leverage: Empirical test of a trade-off hypothesis on French firms

Debt may help to manage type II corporate agency conflicts because it is easier for controlling shareholders to modify the leverage ratio than to modify their share of capital. A sample of 112 firms listed on the French stock market over the period 1998–2009 is empirically tested. It supports an inverted U-shape relationship between shareholders’ ownership and leverage. At low levels of ownership, controlling shareholders use more debt in order to inflate their stake in capital and to resist unfriendly takeovers attempts. When ownership reaches a certain point, controlling shareholders’ objectives further converge with those of outside shareholders. Moreover, financial distress will prompt controlling shareholders to reduce the firm's leverage ratio. Empirically, it is shown that the inflection point where the sign of the relationship between ownership and debt changes is around 40%. Debts may help in curbing private appropriation and appears also as a governance variable.     

Former auditors on the audit committee and earnings management: Evidence from African banks

This paper investigates whether former auditors on the audit committee constrain earnings management through loan loss provisions. Based on an analysis of the annual reports of 82 African listed banks over the period 2011–2016, findings show that the presence of former auditors on an audit committee is associated with lower earnings management. This result suggests that audit committee members with auditing expertise and background contribute to effective monitoring of management’s accounting practices. Furthermore, results reveal that the reducing effect on earnings management of former auditors is strongest for directors who are unaffiliated with the bank’s current external auditor.
