Stochastic frontier analysis

• Workflow for Silva et al. (2017)
• Retrieve data from GYGA

This section provides the workflow to conduct yield gap decomposition using stochastic frontier analysis. Introductory slides can be downloaded here. You will learn (a) how to fit and interpret a stochastic frontier to farmer field data, (b) how to estimate the efficiency yield gap from the fitted model, (c) how to estimate the highest farmers’ yields and the resource yield gap, and (d) how to estimate the technology yield gap using the water-limited yields from the Global Yield Gap Atlas. Please refer to the complementary workflow to access yield data from the Global Yield Gap Atlas.
