英文文献：Is “Good Enough” Good Enough when Hedging Agricultural Commodities?
英文文献作者：Dahlgran, Roger A.
英文文献摘要：
This paper explores the returns to grain producers and processors of expending efforts to determine hedge ratios. We use cash and futures prices from Barchart.com and multi-location cash prices from the Daily Grain Review to determine if location-specific hedge ratios are superior to hedge ratios estimated for a central location then used for hedging at the specific location. We find that the price-risk management capabilities of single location hedge ratios computed the Barchart data perform well in hedging grains at other locations. This suggests that producers and processors should not invest heavily in determining precise hedge ratios that apply to a particular location. In other words, “good enough” hedge ratios are in fact good enough.
