Crop Insurance

Resources for growers

This is a paper by Tannura, et al. on corn yields. This paper calls into question the use of split trend lines to forecast expected yields. This is important to crop insurance because RMA estimates the expected county yield for GRIP/GRP using a split trend line. If these authors are correct and if this also applies to county yields (analysis was at a state level), then some of the expected county yields are overstated.

Are Corn Trend Yields Increasing at a Faster Rate?
