The study investigated how high crop prices affected local economies in the U.S. Heartland during the late 2000s. For every $1 earned in crop revenue, 67 cents were added to the local economy. The money mostly benefited farmers and farm asset owners. However, there was no significant impact on non-farm income, jobs, or population in those areas. This suggests that high crop revenues mainly help those directly involved in farming rather than boosting the overall local economy.
