Why do policymakers and economists within a policymaking institution decide to throw away a model and to adopt or to develop an alternative model? Why do they decide to stick with an existing one? This recurring question surfaced once again after the Great Financial Crisis (GFC), which spurred discussion on maintaining, altering (reforming) or replacing Dynamic Stochastic General Equilibrium (DSGE) models that had spread throughout policymaking institutions in the previous decade.1 Explanations about why models change (or do not change) have hitherto focused on the evolution of academic debates (e.g., De Vroey 2016; WrenLewis 2018; Ingrao and Sardoni 2019) or on the political and institutional transfor∗UCLouvain, ISPOLE; FNRS. †Université Paris-Est Créteil, LIPHA. ‡CNRS; Ecole Polytechnique, CREST. §Universidad de los Andes, Facultad de Economia. ¶Université de Sherbrooke; CIRST. ‖UCLouvain, ISPOLE; USL-B, IEE. 1See e.g. Stiglitz (2011), Romer (2016), or Vines and Wills (2018), for post-crisis debates on the relevance of DSGE. Despite these criticisms and despite the advocacy for new approaches (e.g. Haldane 2012; Mehrling 2010), DSGE models (even if amended and extended) remained widely used in academia and in policymaking institutions, notably in central banks, for forecasting and policy analysis (e.g. Gürkaynak and Tille 2017). Scholars have thus analysed this persistence of the DSGE approach in academia (e.g. Helgadóttir and Ban 2021) and in policymaking institutions (e.g. Mudge and Vauchez 2018).
