| Most of Spanish olive farms are concentrated in Less-Favoured Areas (LFA) with the majority of producer areas are under Objective 1 of the EU Regional Policy. The EU has long recognized such distinctive characteristics of those holdings with a specific support measures aiming to prevent the abandonment of olive groves as well as to support sustainable development of this sector. The main objective of this study is to evaluate the impact of LFA payment on the olive farms technical efficiency. Two sample farms located in LFA (63 farms receiving LFA payment support and 99 farms do not) have been observed from 2000 to 2004. A stochastic frontier production has been used. Results indicate that LFA payment, age of manager, tenure regimes of land, workforce... |

| Spain occupies the first position in the European and Mediterranean rankings of citrus production and trade. In our analysis we assess the technical efficiency with which this sector is operating. The main objective of this study is to analyze productivity and technical efficiency of Spanish citrus sector through citrus farms with high orange production. A stochastic frontier production model is estimated in which the technical inefficiency effects are defined by the time-varying inefficiency model. A primal approach is used to decompose Total Factor Productivity (TFP) growth into its various components. Results indicate improvement in efficiency scores of Spanish citrus farms along the period studied. Allocative efficiencies, technical efficiency change,... |

| The purpose of this paper is the evaluation of the investment decision under uncertainty and irreversibility allowing for long run inefficiency. The analysis has been applied to a 158 Spanish olive farms using FADN data set. A real option approach has been used to analyse the decision to invest under uncertainty and irreversibility, and a dynamic stochastic frontier model has been developed to estimate the long run technical efficiency and it persistence. The results show that the technical inefficiency persistence parameter is fairly low to unity, which means that small technical inefficiency is transmitted to the next time period. The olive groves investment is irreversible and characterized by uncertainty on price and discount rate. An increase of... |

| The concept of technical efficiency is critical to measuring the firm performance, determining the degree of innovative technology adoption and the overall production efficiency. Traditionally, technical efficiency has been measured as the ratio of observed output to maximum feasible output. Stochastic frontier models have been widely utilized to assess this issue. Our research evaluates technical efficiencies in the Spanish olive sector. Specifically, the main objective of this study is to estimate a stochastic frontier production model by using a farm- level panel of data. The non- negative technical efficiency effects are assumed to be a function of firm- specific variables. A sample of Spanish farms observed from 1999 to 2002 is obtained from the FADN... |
