SPECTRAL ANALYSIS OF THE THEORY OF ANTICIPATORY PRICES
用谱分析技术研究小麦、玉米和大豆的现货与期货价格日变化之间的跨期关系，发现小麦和玉米的现货与期货价格每日同步变动，而大豆则不同步。
The paper investigates the intertemporal relationship between cash and futures price changes using the techniques of spectral analysis. Daily data for the wheat, corn and soybean markets are analysed to determine if and how cash and futures prices move together. On a daily basis wheat and corn cash and futures prices move together; soybeans cash and futures prices do not move together on a daily basis.
