In this paper, we investigate the nature of trends in GAT building on the analysis of individual temperature grids. Our micro-founded evidence suggests that GAT is stationary around a non-linear deterministic trend in the form of a linear function with one structural break. This break can be attributed to a combination of breaks on individual grids and the standard aggregation method under acceleration in global warming. info:eu-repo/grantAgreement/ES/MICINN/CEX2021-001181-M info:eu-repo/grantAgreement/ES/MICINN/PID2019-104960GB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2020-114646RB-C42 info:eu-repo/grantAgreement/EUR/MICINN/TED2021-129784B-IO0 info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es 1.8 2024 ECONOMICS 234 / 620 = 0.377 2024 Q2 T2 0.755 2024 Finance 2024 Q2 Economics and Econometrics 2024 Q2 3.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gonzalo, Jesús Ramos, Andrey 4014 225 Universidad de Zaragoza Dpto.
