Abstract

Having robust estimates of how global warming affects agricultural production is important for developing informed policies in response to food security, but the existing studies have been at odds on what this effect might be. This article conducts a meta-analysis based on 130 primary econometric studies to better understand the conflict among the existing estimates of warming on agriculture. We find that the difference in econometric model specification is an important source of disagreement, and that this disagreement can be greatly reduced if the studies model temperature nonlinearly, use a growing season temperature measure, and cross-sectional data which captures adaptations
