agricultural policy
(b) Long-term shifts caused by the influence of productivity improvement on supply.
agricultural policy
a policy concerned both with protecting the economic interests of the agricultural community by subsidizing farm prices and incomes, and with promoting greater efficiency by encouraging farm consolidation and mechanization.The rationale for supporting agriculture partly reflects the ‘special case’ nature of the industry itself: agriculture, unlike manufacturing industry, is especially vulnerable to events outside its immediate control. Supply tends to fluctuate erratically from year to year, depending upon such vagaries as the weather and the incidence of pestilence and disease, S1, S2 and S3 in Fig. 6 (a), causing wide changes in farm prices and farm incomes. Over the long term, while the demand for many basic foodstuffs and animal produce has grown only slowly, from DD to D1D1 in Fig. 6 (b), significant PRODUCTIVITY improvements associated with farm mechanization, chemical fertilizers and pesticides, etc., have tended to increase supply at a faster rate than demand, from SS to S1 S1 in Fig. 6 (b), causing farm prices and incomes to fall (see MARKET FAILURE).
Farming can thus be very much a hit-and-miss affair, and governments concerned with the impact of changes in food supplies and prices (on, for example, the level of farm incomes, the balance of payments and inflation rates) may well feel some imperative to regulate the situation. But there are also social and political factors at work; for example, the desire to preserve rural communities and the fact that, even in some advanced industrial countries (for example, the European Union), the agricultural sector often commands a political vote out of all proportion to its economic weight.
