An AEI analysis by Glauber and Smith reviews the past 20 years of US farm policy, noting growing federal crop insurance subsidies, a shift toward countercyclical payments, and large ad hoc disaster payments tied to China trade disputes and the pandemic. It says the Biden administration is pursuing more subsidies for minority and small farmers and more conservation funding.
Sustained policy support for farm incomes can keep acreage and production decisions tied to program payments rather than price signals, which matters for long-run feed grain supply. Expiring ad hoc payments could weigh on farm incomes and demand for feed if they are not renewed.
