“…Specifically, we allow banks to be treated the same by the public irrespective of the distance between them, for example, banks are allowed to have interbank connections around the whole banking sector. Note that the identification in the spatial models is an ongoing issue (see, e.g., Gibbons and Overman , Gibbon, Overman and Patacchini , and Lee and Yu among others) . Gibbons and Overman (, p. 180) notes that, “in theory if W is not idempotent, identification is possible, but the parameters in the spatial Durbin model are likely only weakly identified in practice.” Note that spatial Durbin model is a combination of the SAR (Spatial Autoregressive Model) and the SLX (Spatial Lag of X) model.…”
