The Impacts of Biofuel Policies on Spatial and Vertical Price Relationships in the US Fertilizer Industry
2021
Bekkerman, Anton | Gumbley, Thomas | Brester, Gary W.
Biofuel policies and concomitant market forces in the mid‐2000s systemically altered US corn markets. Because corn production requires large nitrogen fertilizer inputs, those policies may have also impacted US fertilizer markets. We model fertilizer price relationships across US regions and leverage the natural experiment of biofuel policy intervention to show the secondary impacts on fertilizer markets. Long‐run fertilizer price adjustments became faster and short‐run price dynamics became more responsive to corn markets and less affected by natural gas prices. Additionally, regions where corn production significantly increased after the policies had a 10–20% increase in influencing the fertilizer price discovery process.
