This paper studies the smooth transition regression model where regressors are I(1) and errors are I(0). The regressors and errors are assumed to be dependent both serially and contemporaneously. Using the triangular array asymptotics, the nonlinear least squares estimator is shown to be...

Using monthly data from 1979M1 to 2019M12, this paper employs the AR(p)-EGARCH model and quantile regression to examine the linkages between inflation and inflation uncertainty in nine Asian countries. The results show that inflation positively causes inflation uncertainty in all economies...
