  • Restrictions for biodiesel markets growth: an analysis of transaction
           costs and price transmissions of soybeans from the US to Brazil

    • Authors: Bruno Ferreira Frascaroli, Murilo Massaru da Silva, Evemília Sousa
      Abstract: The present study is aimed to analyze the price transmission of soybeans commodities, the main input for production of biodiesel in Brazil. Our goal was to capture the presence of transaction costs in markets of soybean from a dynamic perspective in the presence of the Law of One Price (LOP). Statistical tests and Vector Error Correction (VEC and TVEC) models were estimated. The results indicated that 1) over the long term, the prices of soybeans and soybean bran quoted in the city of Oeste, Passo Fundo and Rondonópolis tend to follow the changes in commodity price quoted in the CBOT 2) the prices for soybean oil were relatively protected. Also, to developing biodiesel markets in Brazil is necessary minimize the environmental impact of soybean cultivation, mainly on Amazon and Cerrado biomes.

  • La spesa pubblica per l’innovazione nelle politiche di sviluppo rurale
           per uno sviluppo sostenibile dei sistemi produttivi territoriali

    • Authors: Elisa Ascione
      Abstract: This paper analyzes how the rural development policy supports innovation, according to Europe 2020 strategy. Using the information of the Italian FADN 2010-2014, the study analyzes the productivity ratio between large and small farms to measure the gap of their economic performance. The productivity ratio is compared, at regional level, with the consumption of soil for environmental factor and the number of agricultural workers employed for social dimension. The three indicators are compared with public spending for innovation allocated in regional RDPs 2007-2013 and 2014-2020. The results show a weak correlation of public spending with the indicators. Large values of the productivity gap affect negatively on the corresponding values of land use and agricultural employment.

  • L’efficienza dell’agricoltura regionale italiana e le sue

    • Authors: Tommaso Tornese
      Abstract: This paper offers an efficiency analysis of the regional agriculture sectors in Italy. Applying both parametric and non parametric approach for frontier models to regional level data, the article measures the productivity of  regional sectors and investigates the causes of production efficiency. I find that many southern regions have recovered the disadvantage compared to the northern regions during the period analyzed. Furthermore, the work shows that regions with larger firms reach better results, and a more intensive use of organic fertilizer and renewable resources is associated with higher productivity. The models estimated also point out that greater attention to specific education and innovation can improve efficiency.

  • Discussione su “Impresa e non impresa nell’agricoltura italiana. Una
           analisi sui dati del Censi-mento dell’Agricoltura 2010” di Andrea
           Arzeni e Franco Sotte

    • Authors: Antonino Bacarella, Mario Prestamburgo
      Abstract: The deep structural and functional changes occurred over time in the context of Italian agriculture have significantly changed the farms’ operating processes, taking them to identify and practise new productive and commercial strategies. The clear identification of the farm and the enterprise which derives from it remains a relevant matter connected with the construction of public policies interested in the development and enhancement of the production of goods and services in agriculture. The
      Authors suggest a critical analysis of the paper by Arzeni and Sotte, 2013. The discussion highlights the distinction between farms and not-farms through a reading of agricultural census data (6th Italian Agriculture General Census 2010).
