Resumen
Descripción
We analyze the impacts of agricultural subsidies on farm-level production decisions and input use under price, yield, and policy uncertainty for a risk-averse farmer. Using U.S. farm-level data and weighted ordinary least squares, we find that decoupled payments had little impact on agricultural chemical expenditures (our proxy for use) when the payments were first introduced in 1996. However, after 2004 there is a positive, significant relationship between decoupled payments and agricultural chemical expenditures. The results suggest that updating, introduced in 2002, and expectations of future updating caused decoupled payments to become coupled to current input use and, ultimately, production.
