The following paper summarizes existing literature dedicated to efficiency and productivity of organic farming systems. We can distinguish between studies that aim to compare conventional and organic farming and studies that just model samples of organic farms. Sample selection issues seem to be a major problem in some studies, since the organic farming group is often relatively small. Also the structural difference between the groups of organic and conventional farms within the data-sets is seldom discussed in detail. Comparing organic and conventional farms, organic farms perform slightly worse than conventional farms. The inclusion of a sample selection model shows that the conversion to organic farming is not driven by inefficiency. The degree of specialization does not seem to be optimal, nevertheless the limits of specialization are not discussed in detail.
Environmental indicators are only considered in a few studies, which show that organic farming might be more efficient when the environmental dimension of production (such as landscape elements and diversity in the crop-rotation) is taken into account. However, finding appropriate data sets with enough observation for modelling is a problem in these analyses. Investigation shows that technical efficiency depends on the farm focus and varies substantially across the different regions in Germany. Technical efficiency during the conversion period is lower, but converting farms achieve the same efficiency
level as established organic farms after 6—10 years.
