Mango production and exports in Ghana have been increasingly volatile over the past years. After the successful take-off of the sector in the early 2000s, output and international market share decreased. In this study, the reasons for the lacklustre performance on the production side are considered using cross-country survey data from Ghana. In particular, technical inefficiencies and technology gaps of smallholder mango producers are analysed. A metafrontier framework allows for separating production inefficiencies caused by bad agronomic and management practices from technology gaps. The results show that each production zone requires (a) specific targeting programme(s) in order to improve technical efficiency.
