This study estimates the farm-gate breakeven price of switchgrass relative to wheat in Oklahoma. The breakeven price of switchgrass is determined for two situations: when external consequences are ignored and when the environment costs of changes in soil erosion, fertilizer (nitrogen and...

Choice of payment vehicle (PV) is important to contingent-valuation practitioners.
