The dependent variables of models (1) and (2) are the natural logarithm of the coefficient of variation of yield and the natural logarithm of the coefficient of variation of revenue per ha, respectively. “Coeff” stands for coefficient and “SE” for robust standard errors. Statistical significance levels:  = 1%,  = 5%, and  = 10%.
