Abstract
  • The paper adopts the double-bootstrap data envelopment analysis developed by Simar and Wilson in 2007 to estimate and explain technical efficiency of white-leg shrimp farming in Ninh Thuan, Vietnam. This procedure not only enables consistent inference within models explaining efficiency scores but also produces confidence intervals for these efficiency scores. From a policy perspective, our results show that there is considerable room for improvement in technical efficiency in the case of white-leg shrimp farming in Ninh Thuan, Vietnam. The potential improvement is certainly greater than that using the deterministic data envelopment analysis, which has been adopted widely in the aquaculture literature for technical efficiency estimation. Statistically positive influences on technical efficiency are larger farm size and earthen ponds, with breadth of cultural circle and financial stress being negative influences.
