Panel-data analysis shows maintenance improves operational efficiency in Uganda's machinery sector, implying better productivity.

To develop and apply a panel-data econometric framework for measuring efficiency gains in industrial machinery in Uganda.
Conducted a structured survey among engineering managers to evaluate fleet management practices.
Constructed a balanced panel dataset from operational logs of 127 heavy machinery units.
Utilized a fixed-effects estimator to model efficiency based on maintenance adherence and operator training.
Revealed a significant positive link between maintenance adherence and machinery availability.
A 10% increase in scheduled maintenance led to a 2.3 percentage point rise in availability.
Operator training positively impacted efficiency but varied across equipment types.

Kato et al. (2009) studied this question.
