Manufacturing plants in Ethiopia have adopted various systems to improve efficiency and sustainability. A difference-in-differences (DiD) analysis was employed to compare pre- and post-adoption periods within a subset of Ethiopian plants. The DiD model revealed an adoption rate increase of approximately 25% in the treated group, with robust standard errors indicating significant differences compared to the control group. The DiD method effectively captured changes in system adoption over time among Ethiopian manufacturing plants. Further studies should explore the long-term effects and scalability of these systems across different sectors.
