Abstract
Purpose
The purpose of this study is to investigate the role of corporate governance practices on the post-privatization financial performance of the firms listed on the Nigerian Stock Exchange (NSE) over the period 2005-2014.
Design/methodology/approach
The study uses a two-step dynamic system Generalized Method of Moments (GMM) estimation technique for 27 privatized firms by considering a wide range of controlled variables such as managerial shareholdings, board composition, debt financing and stock market development.
Findings
The empirical result suggests that the improvement in the firms’ financial performance is attributed to good corporate governance practices through effective board composition, debt financing (leverage) and stock market development. The result further shows no substantial evidence to support that managerial shareholding improves firms’ financial performance.
Research limitations/implications
Therefore, based on the empirical findings of this study, the authors recommend that the firms need to maintain the optimum board composition and the ratio of debt to share capital as well as developing the stock market to function effectively.
Originality/value
This study contributes to the existing literature in several ways: (1) the first time that the role of corporate governance is considered in explaining the post-privatization financial performance of firms listed on the Nigerian Stock Exchange; (2) the paper applies a two-step dynamic system GMM estimation technique, proposed by Arellano and Bover (1995) and Blundell and Bond (1998) to control for the serial correlation and heterogeneity, which remain the major weaknesses of the panel data modeling in the literature.
