These results are in line with the fi ndings of Sedik et al (1999), who, in addition, explained the decreasing technical effi ciency scores in the period 1993-95 by price changes for agricultural inputs as well as by subsidising the most ineffi cient farms. Furthermore, from their fi ndings, the authors concluded the more specialised a region is in a particular crop, the more effi cient is the production in this region, i.e.…”
