This study considers a cross sectional data of 210 farms to analyze the technical efficiency levels of intensive and semi-intensive fish farms in Ghana using the meta-frontier approach. This technique takes into consideration farms that operate under different technologies. It estimates technology gap that measures output from the frontier production...
This study applies the single-stage modelling stochastic frontier approach to assess the performance of fish farms in Ghana. It examines technical efficiency and its determinants of 150 farms surveyed in 2007 and extend the scope of the analysis to explore interactive effects of farm specific variables on efficiency of production....
