摘要：Crop yield risk analysis is difficult since historic field level yields are often not available. Spatially aggregated yield data are available, however, but aggregation distortion for farm level analysis may exist. This paper addresses how much aggregation distortion to expect and offers some adjustment solutions across crops and production regions.
