Modelling the asymmetric responses of price level to oil price changes in Qatar حسب Mrabet, Zouhair

"…To achieve that, we proceed by employing a nonlinear autoregressive distributed lag (ARDL) approach on data during the period 1990Q1-2014Q4. The estimation results show evidences of an incomplete and asymmetric influence of oil price on price level in the long term. …"

Asymmetric effects of oil price shocks on the demand for money in Algeria حسب Amirouche, Chelghoum

"…This paper investigates the symmetric and asymmetric effects of real oil prices on real money demand in Algeria over the period 1999:Q1–2020:Q1. Using a linear autoregressive distributed lag model (ARDL), and a nonlinear autoregressive distributed lag model (NARDL), we find no evidence of a long-term relationship among the variables. …"
