“…This backward-looking nature of the model makes it subject to the Lucas critique, according to which reducedform relations in traditional macroeconomic models depend implicitly on the agents'expectations of the policy process and are hence unlikely to remain stable as policymakers changed their rules. However, empirical backward-looking models without explicit expectations are still widely used for monetary policy analysis, as in Rudebusch andSvensson (1998, 2002), Onatski and Stock (2002), Smets (1998), Dennis (2001), Laubach and Williams (2003), Fagan, Henry and Mestre (2001) and Fabiani and Mestre (2004). Moreover, several articles suggest that such models appear to be fairly robust empirically, notably Rudebusch and Svensson (1998), Bernanke and Mihov (1998), Estrella and Fuhrer (1999), Dennis (2001) and Leeper and Zha (2002).…”
