While there is growing recognition of the positive role played by organic farming in the reduction of the negative externalities due to conventional agriculture, there is uncertainty about the effect of the latter on the economic performance of the farms. In this scenario, the present paper aims at investigating the effect of organic farming on technical efficiency in Italian olive farms. A cross-section dataset was analyzed through the stochastic frontier function, where the adoption of organic farming was explicitly modeled. Then, to obtain an unbiased estimate of the impact of organic farming on technical efficiency, a propensity score matching method was implemented. The findings reveal that organic farming increases technical efficiency in Italian olive farms by approximately 10%. The highest impact of organic farming is observed in small farms. As for the propensity to become organic, we found that the production and the direct sales of a higher quality of gross marketable output, as well as the intensity of labor and machines, increase the probability to adopt organic farming. Conversely, farm localization, the availability of family labor, and financial capital discourage conversion to the organic farming system.

The technical efficiency measures the ability that a system offers at maximizing the result restricted to budgetary restrictions. This article offers formal methods to quantify the technical efficiency in health systems and the influences of organizational structures and internal processes in the observed technical efficiency are also analyzed. The empirical analysis is focused on the quality of donation and transplant services. The results show a positive relationship between the levels related to quality indicators and the observed technical efficiency in the donation and transplant units of the 11 analyzed hospitals. This way it is possible to conclude that high levels in the quality indexes are a necessary condition to reach an increased level of the service offered.
