This paper estimates agricultural total factor productivity (TFP) in 162 countries between 1991 and 2015 aims to understand sources of cross-country variations TFP levels its growth rates. Two factors affecting are analyzed detail - imported intermediate inputs climate. We first show that these two independently important explaining raise TFP; higher temperatures rainfall shortages impede growt...
