Starchy staples production shortfalls in Ghana: Technical inefficiency effects outweigh technological differences across ecologies.

Starchy staples are a major source of livelihood support for farmers, traders, and processors who participate in these crops' value chains, while also providing staple food to many people, especially the less affluent in society. Despite this position, the productivity figures of starchy staples are low. We use a unique data set and meta-frontier efficiency analysis to assess whether the production shortfalls of major starchy staple crops in Ghana could be attributed to technical inefficiency, technology gaps or both.

Innovations in smallholder agricultural financing and economic efficiency of maize production in Ghana's northern region.

This study used PSM and the selectivity-corrected framework for stochastic frontiers to examine how innovative agricultural finance practices of maize farmers in northern Ghana affect economic efficiency. We find, consistently, that users of innovative financing have higher technical (TE), allocative (AE), and economic efficiency (EE) scores than nonusers. The efficiency gaps between users and nonusers are 4% for TE; 5% for AE; and 10% for EE.
