Dear colleagues and fellow Dynare users, We are pleased to share a newly published technical working paper by our colleague, Normann Rion, titled: "Rich Heterogeneity in Dynare 7: A Practical Description". This paper provides a detailed look under the hood of Dynare's new tools for Heterogeneous Agent New Keynesian (HANK) models. Normann outlines the critical algorithm and interface choices that were made, making this an essential resource for advanced users and researchers looking to effectively use and understand these complex models within the Dynare framework. You can download the full paper directly from the Dynare WP repository here: https://www.dynare.org/wp-repo/dynarewp088.pdf Best regards, Willi Dynare Team
