Asymmetric oil price transmission to the purchasing power of the US dollar: A multiple threshold NARDL modelling approach

This paper studies, whether the responses of the purchasing power of the U.S. dollar asymmetric to crude oil price fluctuations? A multiple threshold nonlinear autoregressive distributed lag model (MTNARDL) is developed to address this question. Working on the monthly data from January 1990 to June 2019, this study shows a shortrun asymmetric transmission of oil price fluctuations into the purchasing power of the U.S. dollar. The results of the MTNARDL model apprehend, more minutely, the magnitude of variations in purchasing power in response to minor to major change in the oil price. It finds corroborative evidence for more rapid response of the purchasing power to the upward oil price shocks than to the downward movement in the oil price. This implies that the purchasing power of the U.S. dollar experiences sharp reduction with the rise in the oil price, nonetheless, the advantage of a drop in the oil price is not entirely transmitted to the purchasing power as its correction takes much longer period than expected.
