ABSTRACT. Onumah et al. show how specific producer organizations and relatively large end-users can structure long-term supply arrangements on the basis of internationally accepted standards and rules or mutually agreed terms and conditions. Emlinger et al. write that the regulation of trade with third countries, in the fruit and vegetable sector, is the key element in the common organization of the market. Anania and Nisticò present an analysis of the decisions of producers and consumers of a credence good in three institutional scenarios. Scandizzo and Savastano show that when the hypothesis of decreasing return to scale holds, the relation between the threshold value of revenue per hectare and the amount of land cultivated is positive.
