The yield and price effects of growing genetically modified corn: evidence from the US corn belt
by Prince Fosu
International Journal of Biotechnology (IJBT), Vol. 14, No. 4, 2023

Abstract: This study investigates the impact of GM corn adoption on yield and price for the US corn belt from 2014 to 2020. In addition, the study investigates the interaction effects of GM corn and yield on price and analyses the impact of both temporary and permanent shocks of growing GM corn on yield and price. The results indicated that the GM corn adoption had a positive impact on yield and a negative and statistically significant impact on price. Also, the interaction effect of GM corn and yield impacted positively on the price, suggesting that the adoption of GM corn should increase the negative effect of yield on price. The temporary shock of growing GM corn positively impacted yield and price while the permanent shock negatively affected yield and price. The study suggested that the adoption of GM corn has implications for improving producer and consumer welfare and global food security.
