Dear Colleagues, I am delighted to extend you the invitation to participate in the IIASA-MacroABM 1st Workshop. Below is a short description of the workshop and the link to its website: “The macroeconomic agent-based model (MABM) started at IIASA is gaining momentum. Researchers and practitioners working on the model, both from academic and policy institutions, will meet on April 18-19th in Schloss Laxenburg. This workshop will facilitate exchanges on the model, create a space to get help on practical issues, and share ideas. Macroeconomic agent-based models (MABM) generate the relevant macro-aggregates of a national economy from the micro-founded behavior of heterogeneous agents. MABMs have the potential to enrich the toolboxes of policy institutions such as central banks, enabling finer analyses of monetary and fiscal policies. The MABM developed at IIASA, described in Poledna et al. (2023)<https://www.sciencedirect.com/science/article/pii/S0014292122001891>, competes with state-of-the-art standard models in forecasting and uses publicly available data for calibrations. It is gaining momentum and has recently been adopted by the Bank of Canada<https://www.bankofcanada.ca/> (CANVAS<https://www.bankofcanada.ca/2022/12/staff-working-paper-2022-51/>) to enrich its in-house macroeconomic models. The code has been re-implemented on various platforms, and the model is being extended and reworked in several directions. The goal of this workshop is to bring together scientists and practitioners who develop, use, or are interested in using the model in any of its versions. We aim to exchange successes and failures, good practices, and ideas.” https://iiasa.ac.at/events/apr-2024/iiasa-macroabm-1st-workshop Best Regards, Luca Fierro
