The Impact of Cumulative Career Experience of Internal Control Managers on Firms’ Efficiency in Different Information Environments

초록

This study investigates the effect of internal control (IC) managers’ cumulative career experience on the operational efficiency of Korean listed firms between 2018 and 2020. Building on the premise that managers with extensive experience positively influence ICs and the internal information environment, this study hypothesises that cumulative career experience of an IC manager is also positively associated with a firm’s operational efficiency. To empirically assess efficiency, this study applies data envelopment analysis (DEA), a nonparametric technique that evaluates relative efficiency based on multiple input and output measures. The results suggest that IC managers with greater cumulative experience significantly enhance a firm’s efficiency. Moreover, this effect is more pronounced in firms operating within weaker accounting information environments, where managerial experience plays a critical role in improving efficiency. © 2025 School of Economics and Business University of Ljubljana.
