Given the time and budget constraints that all researchers are subjected to, this is probably not a realistic approach. A general conclusion, that is applicable to all empirical applications is that it is important to be aware of the potential limitations in the data when interpreting the results. g. DEA and SFA that were described in chapter 3), which are important to keep in mind when interpreting the results. They were mentioned in the introduction of chapter 3, but we think it is meaningful to end this chapter by once more emphasising some of these points.
However, one should remember that it is possible that even the best practice farms in the sample could become more efficient if their production processes were optimized according to some theoretical standard. DEA is a mathematical programming approach which calculates an efficiency index of each farm in the sample by solving a linear program. The method was originally developed by Charnes, et al. (1978), and does not require any prespecification of functional form. It is deterministic in its nature, meaning that it does not take noise in the data into consideration.
Sharma, et al. (1999) studied, among other things, the effect of farm size and economic, technical and allocative input-oriented efficiency on pig farms in Hawaii. They used both the data envelopment analysis and the stochastic frontier approach to assess the efficiency score. In second-stage regression analyses the effect of farm size was determined. The results showed that farm size, measured in the number of sows, significantly and positively affected all efficiency scores, suggesting that larger farms are more efficienct.
