Based on time series of crude oil prices (daily spot), this paper analyses price fluctuation with two significant parameters [tau] (speculators' time scales of investment) and [epsilon] (speculators' expectations of return) by using Zipf analysis technique, specifically, by mapping [tau]-returns...

The fractal behaviour for petroleum pricing is investigated in several international systems. Based on the time series of Brent & WTI crude oil and Rotterdam & Singapore Leaded gasoline prices (daily spot), this paper analyses the fractal features in the systems under study by using Rescaled...
