How firms' performance mediates the relationship between corporate governance quality and earnings quality?

Purpose - The purpose of this study is to propose an analytical model that investigates both a direct path between corporate governance quality and earnings quality and an indirect path, in which firms' performance is a mediating variable that is influenced by corporate governance quality and that, in turn, influences earnings quality. Design/methodology/approach - The study employs a structural equation modelling (SEM), to a sample of Egyptian listed firms during 2011–2017, to test the proposed analytical model and to determine the relative importance of both the direct and indirect paths. Findings - The findings show a statistically significant evidence of both a direct path from corporate governance quality to earnings quality, and an indirect path that is mediated by firms' performance, suggesting that both corporate governance quality and performance have a complementary effect on earnings quality. However, the weight of the evidence favouring the direct path is more important in case of accounting-based performance measures; and the weight of the evidence favouring the indirect path is more important in case of market-based performance measures. Research limitations/implications - The current study has some limitations. First, the study focuses specifically on one proxy for measuring earnings quality which is the absolute value of discretionary accruals. Other proxies of earnings quality could be examined in future research, such as income smoothing, earnings persistence and timely loss recognition. Another limitation is that only financial performance measures were examined, namely, return on assets, return on equity, price-to-earnings ratio and market-to-book value. Notwithstanding, non-financial performance measures could be investigated in future studies, such as balanced scorecard (BSC). Furthermore, considering cultural, political and legislative differences among countries, the results may not be generalised outside the scope of the current sample (i.e. Egyptian listed firms). Practical implications - The implications of the findings for both theory and practice are discussed. Originality/value - This study is distinguished by validating an analytical model that has been overlooked by prior studies. Moreover, it provides a new constructed index for measuring corporate governance quality. Furthermore, it uses a new sophisticated statistical technique, which is SEM, for testing the proposed model.
