This paper evaluates the impact of the Purchase 4 Progress (P4P) intervention implemented by World Food Program in Ethiopia on per capita income as well as across sub-social groups. The intervention is intended to improve the market power of smallholder farmers through cooperatives that has the...

This study used the by-production model specification to separate emission-generating technologies from ‘desirable outputs’ technology. It then employed the dynamic efficiency model, following the Dynamic Directional Input Distance Function specifications to compute the deterministic,...

This paper assesses the effect of extreme weather variability in predicting the impact on two agricultural crop-related variables: yield and production. We use a Markov-Switching time-varying copula to describe the joint dependence structure between extreme weather variability and crops in East...

Concerns about the human effects of climate change have contributed to forecasts of how populations in drought-prone, and flood-prone areas would respond to these events. Empirical studies have predicted that human migration has been among the critical resilient strategy in responding to the...

The relationship between economic growth and environmental pollution continues to attract undying research interest. While existing studies focused on examining the relationship from growth to pollution or pollution to growth, research on the causal relationship between the two variables is...

Climate change has occasioned several Earth long-term events, including extreme temperatures. In recent years, Africa was reported as part of the world's regions that experienced extreme temperatures above pre-industrial levels. Despite lower contribution to Green House Gas (GHG) emissions and...

The African Continental Free Trade Area (AfCFTA) agreement was signed by at least 54 African countries and has the potential of lifting up to 30 million Africans out of extreme poverty, according to the World Bank (2020). The agricultural sector is regarded as a fertile ground for achieving the...

Energy transition has imposed a policy priority dilemma between economic growth and global warming mitigation. Existing studies in Africa have examined the impact of energy sources on growth but overlooked the differences across countries and regions. This study seeks to achieve two research...

Designing a desirable block tariff structure for residential water use has been a challenging task for regulated utilities. In this study, we investigated whether the existing increasing block tariff design addresses the issue of affordability, especially for lower-income groups. Using the South...

An increasing number of countries around the world have linked taxes with passenger vehicle carbon dioxide (CO2) emission rates. Policymakers use vehicle and fuel taxes to target and reduce transportation greenhouse gas emissions. In 2010, the South African government joined this group, linking...
