Does attending seminars affect technical efficiency of white shrimp (Litopenaeusvannamei) aquaculture?

Measuring technical efficiency and examining the factors affecting technical inefficiency of brackish water white shrimp aquaculture in Malaysia are the objectives of the study. This study applies a parametric approach (stochastic production function, SPF) and a non-parametric approach (data envelop...
