Export restrictions in producing countries and price controls in importing countries both serve to exacerbate the magnitude of the world price upswing, owing to the artificially reduced quantity that is still internationally traded. If producing and consuming countries in grain markets could cooperatively agree to refrain from such government intervention – probably by working through the World Trade Organization – world price volatility might be lower.
生产国的出口限制和进口国的价格管制都会进一步推高世界价格，这是因为进入国际贸易环节的商品数量被人为压低了。如果谷物生产国和消费国精诚合作，阻止此类政府干预——可以通过世界贸易组织来实现——世界价格的波动性是可以降低的。
