Modeling Impacts Of Soil Conservation On Productivity And Yield Variability: Evidence From A Heteroskedastic Switching Regression

Author

  • Shively, Gerald E.

Abstract

The impact of soil conservation adoption on yield and yield risk is investigated using a conditionally heteroskedastic production function with endogenous switching. Analysis shows that controlling for plot-specific factors, adopters exhibit lower yields and higher yield variance than non-adopters. Regression results indicate soil conservation increases yields and reduces yield variance.
