We propose an alternative approach to examine the nonlinear (asymmetric) behaviour of interest rates which can be both size and sign dependent. Compared to other widely used approaches, our model performs quite well based on two model selection criteria.

This paper presents evidence that the price of oil does not respond contemporaneously to shocks to the US gasoline market. We find no support for the hypothesis of feedback from the US gasoline market to the price of oil, justifying the identification of impulse response functions by applying a...

We reinvestigate the "rockets and feathers" effect between retail gasoline and crude oil prices in a new framework of fractional integration, long-term memory and borderline (non)stationarity. The most frequently used error-correction model is examined in detail and we find that the prices...
