Organic and Conventional Grape Growing in Italy: a Technical Efficiency Comparison Using a Parametric Approach

Several studies have focused attention on the differences between organic and conventional farms in terms of efficiency, controversial findings resulted from these applications. One source controversy concerns assumption about frontier(s) adopted for comparison: a common frontier or two separate frontiers methods? This paper aims to estimate technical efficiency Italian grape farming. A stochastic analysis (SFA) was applied sample 531 (440 91 farms) collected Farm Accountancy Network Database. Among others, test evaluating whether unique performed. The suggest that would lie greater capacity than using their own inputs (efficiency amounts 83.6% 77.8%, respectively). number implications derive findings.
