Model simplification and variable selection: A Replication of the UK inflation model by Hendry (2001)

In this paper, we revisit the well-known UK inflation model by Hendry (Journal of Applied Econometrics 2001, 16:255-275. doi:10.1002/jae.615). We replicate the results in a narrow sense using the gretl and PcGive programs. In a wide sense, we extend the study of model uncertainty using the Bayesian averaging of classical estimates (BACE) approach to compare model reduction strategies. Allowing for the investigation of other specifications, we confirm the same set of significant determinants but find that Hendrys' model is not the most probable.
