Bivariate threshold excess model
Webary. Compared to the ordinary threshold model, where typi-cal the lag variable xt-' is the threshold variable, this is a somewhat indirect way of formulating a nonstationary threshold VAR model. In this article, we start directly from the VAR representation (1.1) and then move to the threshold VAR representation (1.4) http://www.mas.ncl.ac.uk/~nlf8/publications/markov.pdf

This review suggests that the model generating the various aspects of inflation is an important measure for examining the relationship.
