Methodological Scrutiny of Manufacturing Systems Efficiency Gains in Uganda Through Difference-in-Differences Analysis
type: item
description: Recent studies in Uganda have shown mixed results regarding efficiency gains in manufacturing systems. However, these studies often lack robust methodological frameworks to accurately measure and analyse such gains. The DiD model will be employed to analyse changes in manufacturing plant performance before and after certain interventions, such as policy reforms or technological upgrades. This approach allows us to isolate the effect of these interventions from other potential confounders. This theoretical framework lays out a robust methodology for future empirical studies on manufacturing system efficiency in Uganda and beyond. Future researchers should consider the DiD model as a foundational tool to assess and report efficiency gains in manufacturing systems, ensuring transparent and replicable results. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Bayesian Hierarchical Model for Evaluating Cost-Effectiveness in Secondary Schools Systems in Kenya
type: item
description: The secondary schools system in Kenya faces challenges related to energy efficiency and cost-effectiveness. A Bayesian hierarchical model was developed to estimate the cost-effectiveness of different energy technologies used in Kenyan secondary schools. The model accounts for variability at multiple levels including school-specific characteristics and regional differences. The analysis revealed that solar photovoltaic systems were most cost-effective, with an estimated average return on investment within a 95% credible interval of [1.2 to 3.4] years. This study provides evidence supporting the adoption of solar energy solutions in secondary schools as a viable and financially beneficial approach. School administrators should prioritise the implementation of cost-effective renewable energy systems, such as solar photovoltaics, based on this model’s findings. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Renewable Energy Technologies and Women's Employment in Kenyan Coffee Plantations
type: item
description: Renewable energy technologies (RETs), such as solar panels and biogas digesters, have been introduced to Kenyan coffee plantations over the past two decades, aiming to reduce reliance on fossil fuels and enhance environmental sustainability. A mixed-methods approach combining quantitative surveys with qualitative interviews was employed. The survey collected data on gender-specific employment patterns, while the interviews explored perceptions and experiences related to RET use. Women reported a significant increase (p<0.05) in leisure time by 20% after installing RETs, which allowed them more flexibility in managing household chores and childcare responsibilities. RET installations have led to both positive and negative employment impacts on women, particularly regarding their ability to balance work and family commitments. Policy makers should consider gender-specific benefits of RETs when implementing such technologies in agricultural settings. Women’s input is crucial for tailoring interventions that maximise social welfare. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
