Abstract
This paper suggests the use of a particular parametric test when comparing the efficiency scores resulting from efficiency analysis. As an illustrative case Data Envelopment Analysis (DEA) is run on a set of Danish dairy farm data. Assuming that the efficiency scores resulting from DEA are right censored log-normally distributed, the influence of potential external factors affecting the efficiency can be investigated. It is found that efficiency increases with size and more surprisingly, that farms with jersey cows tend to be more efficient than non-jersey farms.
