摘要：Using historical production data at the county level and statistical analysis, we investigate climate contributions to corn and soybean yields between 1974-2003. Crop yield trends are decomposed into two components: the technology-derived trend and the trend resulting from climate variability. Implications for agricultural risk management and farm policy are discussed.
