Chapter 4 infrastructure, etc. Only some of these factors can be improved by policy interventions, and some factors may even deteriorate during the transition period of adjustment (infrastructure, social/political stability). If, due to such factors, a country fails to attract additional foreign investments, the easing of restrictions on capital transfers may result in additional outflows of foreign exchange and a worsening balance of payments situation. 7. Agricultural Market Reforms and Sectoral Adjustment Markets in many developing countries have been subject to substantial government intervention. Although intended to achieve higher stability and efficiency in marketing operations by ruling out speculation of middlemen and by making use of economies of scale, direct government interventions in the process of price formation and marketing operations have proved to be often highly inefficient and ineffective, undermining what they were intended to achieve. The market rigidities and high marketing costs, typically associated with officially regulated marketing systems, have prevented markets from fulfilling their basic functions of * providing an efficient and effective link between producers and consumers, * establishing marketing margins which cover the marketing costs. * giving sufficient incentives to the producers, * allocating production according to existing potentials,' * indicating the appropriate prices to consumers, as far as relative scarcity and costs of production are concerned, * finding an equilibrium between supply and demand. Altogether, these factors have contributed to the growing structural imbalances as shown on the right side of Figure 4.2 (see page 116), Box 4.5 illustrates a typical case of market and price distortions from the Zambian food sector during the eighties. In consequence, market and price reforms constitute one, often the. major element of structural adjustment programmes. They comprise measures of price and market liberalisation, including reforms of the marketing institutions (see section 8.1 below). Although these are fundamental issues for all sectors and for the economy as a whole, they are usually embedded in sectoral adjustment policies and programmes, in order to give proper attention to the relative importance and the specific problems and conditions of the various sectors of an economy. According to the relative importance of the agricultural sector, agricultural sector policies form the core of most structural adjustment programmes. The major elements of agricultural sector reform are: * agricultural pricing policy; * reforms of agricultural marketing institutions; -154-
