- Robust standard errors in parentheses; **p < 0.05, *p < 0.1; no standard errors are reported for the rainfall variable. Because of undesirable coefficient signs, we modified the value of the rainfall variable using a synthetic estimation technique. A synthetic elasticity coefficient value of 1.65 was used to obtain the rainfall coefficient. Given the high dependency of maize production on rainfall, the use of a 1.65 elasticity value is reasonable
