Some Productivity‐Increasing and Quality‐Changing Technology for the Soybean Complex: Market and Welfare Effects
模拟表明，低蛋白高油大豆会改变市场品质和数量，替代蛋白饲料会抵消豆粕供应减少的收益，美国整体无净福利增加，但联合增产和成分变化会因饲料降价和豆油加工竞争力提升而带来福利。
Abstract Simulations suggest that soybeans with less protein and more oil would alter quality and change quantities on the market. Substitution toward other protein feeds, like fishmeal, would mitigate the benefits from restricted soymeal supply. Thus, there would not be a net welfare gain for the United States, only a redistribution of benefits. But a joint yield increase and composition change would benefit the United States, mainly because livestock producers would pay lower feed prices. Also, industrial processing of soybean oil would become competitive. Hence, soybean research should pursue yield increases by allowing protein reductions.
