The impact of corporate governance measures on firm performance: the influences of managerial overconfidence

Abstract

Abstract The paper aims to investigate the impact of corporate governance (CG) measures on firm performance and the role of managerial behavior on the relationship of corporate governance mechanisms and firm performance using a Chinese listed firm. This study used CG mechanisms measures internal and external corporate governance, which is represented by independent board, dual board leadership, ownership concentration as measure of internal CG and debt financing and product market competition as an external CG measures. Managerial overconfidence was measured by the corporate earnings forecasts. Firm performance is measured by ROA and TQ. To address the study objective, the researcher used panel data of 11,634 samples of Chinese listed firms from 2010 to 2018. To analyze the proposed hypotheses, the study employed system Generalized Method of Moments estimation model. The study findings showed that ownership concentration and product market competition have a positive significant relationship with firm performance measured by ROA and TQ. Dual leadership has negative relationship with TQ, and debt financing also has a negative significant association’s with both measures of firm performance ROA and TQ. Moreover, the empirical results also showed managerial overconfidence negatively influences the relationship of board independence, dual leadership, and ownership concentration with firm performance. However, managerial overconfidence positively moderates the impact of debt financing on firm performance measured by Tobin’s Q and negative influence on debt financing and operational firm performance relationship. These findings have several contributions: first, the study extends the literature on the relationship between CG and a firm’s performance by using the Chinese CG structure. Second, this study provides evidence that how managerial behavioral bias interacts with CG mechanisms to affect firm performance, which has not been studied in previous literature. Therefore, the results of this study contribute to the theoretical perspective by providing an insight into the influencing role of managerial behavior in the relationship between CG practices and firm performance in an emerging markets economy. Hence, the empirical result of the study provides important managerial implications for the practice and is important for policy-makers seeking to improve corporate governance in the emerging market economy.
