In this article, we used bootstrap data envelopment analysis techniques to
examine technical and scale efficiency scores for a balanced panel of 564
farms in Kansas for the period 1993–2007. The production technology is
estimated under three different assumptions of returns to scale and the
results are compared. Technical and scale efficiency is disaggregated by
farm size and specialization. Our results suggest that farms are both scale
and technically inefficient. On average, technical efficiency has
deteriorated over the sample period. Technical efficiency varies directly by
farm size and the differences are significant. Differences across farm
specializations are not significant.
