Methodological Evaluation of Manufacturing Plants Systems in Uganda Using Difference-in-Differences Models to Measure Efficiency Gains

Manufacturing plants in Uganda are pivotal to economic growth but face challenges related to inefficiency. A meta-analysis approach was employed, synthesizing data from multiple studies on Ugandan manufacturing efficiency. The difference-in-differences model revealed an average improvement of 15% in plant efficiency across analysed sectors, with significant variation between industries. This study underscores the potential for targeted interventions to enhance overall manufacturing efficiency in Uganda. Policy makers should prioritise sector-specific support programmes based on findings from this analysis.
