The model is a vector autoregression with coefficients that are random walks with innovations that are arbitrarily correlated with each other and with innovations to the observables. The model enables us to detect features that have been emphasized in theoretical analyses of inflation-unemployment dynamics. Those analyses involve coefficient drift in essential ways.
