(introduction...)

2.40 A wide range of technical, institutional, and other measures can be adopted to facilitate the flow of information, goods, money, and product ownership rights in commodity systems, to achieve economies of scale and reduce the risks and transaction costs associated with food procurement and marketing, to internalize externalities, and to provide those public goods necessary for efficient market development. Many of these measures are essentially market or quasi-market responses on the part of private firms and individuals; others entail government interventions which stimulate, re-direct, constrain, or supplement private activity. While the available space here does not permit a comprehensive discussion of this wide array of technologies and institutions, this section does examine an illustrative sample of such measures, noting their potential for promoting improved efficiency, coordination, competitiveness, and other objectives.
