英文文献:The Effect Of Distortions In Relative Prices On Corn Productivity: A Cross-Country Study
英文文献作者:Lyons, David C.,Thompson, Robert L.
英文文献摘要:
Pooled data from 14 large corn producing countries for 13 years show that the corn-nitrogen price ratio, as well as physical factors and technology, account for a significant part of corn yield differences among countries. Policies which distort corn and fertilizer prices have a significant effect on corn yields.
