The 'art of policy' consists in finding the 'golden' middle course, by compromising but also by setting priorities as far as the objectives are concerned, and by allowing as much free market movement as possible, with only as much intervention as necessary to correct market failures and to emphasise certain political priorities What is possible and necessary, depends on the specific socio-economic conditions of a country, on the policies applied in the past, on the political priorities pursued by the present government, and, in the case of debtor countries, on what the foreign donors and financial institutions consider as 'good' or 'bad' policies. All these factors are reflected in adjustment programmes and have to be considered when the impacts of such programmes are analysed. In order to do such an analysis for the agricultural sector and the food economy, the following factors need to be taken into account: * the natural resource endowment with its specific constraints and potentials for agricultural and food production, * the human factor and resources, * the prevailing physical, technical and social patterns of agriculture and food production. * the existing agricultural and food marketing system, * the food situation (including structure of prevailing food deficits, see Annex 1). * the macro-economic and sector policies pursued in the past with their consequences, * the political mainstream as reflected in the objectives of adjustment programmes. 7.2 Price policy instruments The major pricing policy instruments and their principal effects are listed in the following table: Table 4.15: Major pricing policy instruments and effects Policy type Major instrument Principal economic effect Trade policies subsidy/tax on imports/exports prices of traded goods change; indirect effect on potential tradables import/export quota indirect effect on prices of tradables Exchange rate policies nominal exchange rate prices of traded goods change; may lead to pressures on prices of non-tradables, e.g. labour Market system policies subsidies/taxes prices of affected goods change administered prices rationing; black-market transactions: or budgetary costs Production input policies minimum wage; land tax; interest changes allocation of domestic resources; rate or other import subsidies affect labour/capital mix of production Adapted from FAO, 1991, Economic analysis of agricultural policies, Training materials for agricultural planning No. 30 - 158-
