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.     

Estimating scale economies in financial intermediation: a doubly indirect inference

This paper provides a vertically integrated modelling of the financial production process. In a first stage the activity of commercial banks or insurance companies embodies some technical and commercial aspects such as services to depositors or mutualization of risk through distribution of contracts of insurance. In the second stage banks are involved in the intermediation activity. By using a simulation and the doubly indirect inference method for the estimation we were able to resolve two main econometric problems: decomposition of aggregated data over two vertically integrated stages of production and inconsistency of the estimators due to endogeneity and misspecification. An application to French Banking industry is provided.     

Variety expansion,preference shocks,and financial intermediaries

We investigate the effect of lifetime uncertainty on economic growth by incorporating preference shocks into a variety-expansion model and comparing financial autarky and financial intermediaries. In this economy, long-term investment facilitates the promotion of R&D investment and the creation of new differentiated goods. Our results suggest that when risk aversion is high, an increase in number of differentiated goods slows down R&D investment through a decrease in the price index. Further, if the risk of early withdrawal and the liquidation cost of long-term investment are high, financial intermediaries have significant effects on the growth of variety.     

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.     

Human capital and FDI: Development process of the developing country in an overlapping generation model

We construct an overlapping generation model with human capital accumulation to analyze the effect of human capital level on foreign direct investment (FDI) in a small open developing country. In particular, we assume that manufactured goods have the human capital intensive technology and young agents choose whether to work or to educate themselves. When the human capital level in the developing country is sufficiently small, manufactured goods firms do not conduct FDI and the economy in the developing country is trapped in poverty. If the government of the developing country levies a tariff on the imports of manufactured goods, manufacturers conduct FDI, and the economy in the developing country can escape from the poverty trap.     

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.
