Previous econometric studies have established a relationship between weather and the degree of skewness in the distribution of crop yields. An important factor in determining the shape of the distribution is the existence of a constraining maximum yield level. Here, farm‐level yields and simulation results from a mechanistic crop model provide insights into the implications of weather variations and an upper limit on corn yields. The results indicate that moments of the distribution of corn yields are sensitive to changes in temperature and precipitation. A warmer, drier climate is associated with lower yields and a flatter, more symmetric distribution.
