| The present study utilizes the stochastic production frontier approach in evaluating the technical efficiency rates achieved in four types of Greek organic and conventional farm operations, namely, olive oil-producing, cotton, raisin-producing, and grapes-for-wine producing farms. The empirical results are expected to illustrate possible differences in the technical efficiency scores between the two farming technologies, and provide empirical evidence which at least in the field of organic farming performance is scarce or even absent. Such assessments may also be helpful for pointing out purely economic advantages (or disadvantages) of organic farming, in addition to its environmental dimension, and formulating policies to improve its economic performance. |

| Using recent advances in the stochastic production frontier framework, this paper presents an empirical analysis of technical, allocative and economic efficiency of a sample of organic and conventional cotton farms located in Greece. The results suggest that both farm types in the sample examined are technically, allocatively and economically inefficient. Farmer's age and education and farm size are important factors in explaining differentials in efficiency estimates. In comparative terms, organic farms exhibit lower efficiency scores vis-à-vis their conventional counterparts in terms of technical and economic efficiency; regarding allocative efficiency both farm types are almost equally inefficient. Low efficiency scores in both types of farming may... |

| This analysis empirically evaluates a subset of Japanese agricultural policies during the 1970s and 1980s using the Trade Restrictiveness Index recently developed by Anderson and Neary. This index, though theoretically rigorous, is empirically demanding, resulting in relatively few applications. Inferences obtained from the index are in general accordance with policy changes and economic events over the period of analysis. Using 1970 as the base, the estimated TRI suggests that policy changes during 1970-87 resulted in moderately liberalized trade. Comparison with a conventional measure of trade distortion- producer and consumer subsidy equivalents (PSEs and CSEs)- reveals contrasting inference. This suggests the choice of empirical measures in evaluating... |
