Abstract: | The efficiency determinants of manufacturing firms in developing countries have received increasing attention over the past few decades. This study examines the role of top managers' human capital and other exogenous determinants of the efficiency of manufacturing firms in Bangladesh by using heteroscedastic single‐step stochastic frontier analysis. We find that general human capital represented by educational qualification and specific human capital formed by work specific experience show different ways of impact on firm performance. Specifically, education has both a direct impact on firm outputs and an indirect impact as an efficiency determinant, whereas experience affects only technical efficiency. |
