Topic characteristics
The thesis will focus on multifractal analysis of changes in price of petrol and diesel in the Czech Republic. Starting from raw time series of prices, which would need to be adjusted for taxes to be usable for our analysis, since both petrol and diesel are heavily taxed. The auto-correlation function would suggest strong signi�cance with long lags. Using common sense only, one would expect them to show the same behavior as crude oil, the core element of both fuels. However, crude oil market is much more e�cient and does not show the same long memory as fuels. This suggests that both fuels are fractal processes. We will try to �nd a proper model for the time series using both fractal and multifractal analytics. To the author's best knowledge, this kind of analysis has not been performed with the fuel prices yet. Hypotheses At this early stage of the research, we expect the changes in petrol and diesel prices to be strongly auto-correlated. To have long memory and thick tailed distributions. Additionally, the time series are expected to be multifractal. Methodology The time series cover long time data of petrol and diesel retail prices for the Czech Republic. To analyze them thoroughly adjustments for taxes will be required, because both excise tax and value added tax have been changed during the time window. Further, the time series will be examined via variance scaling, AutoRegressive Fractionally Integrated Moving Average (ARFIMA) and Maximum Likelihood Estimator (MLE). Outline 1. Introduction 2. Theoretical Background 3. Related Work 4. The Model 5. Empirical Veri�cation 6. Conclusion |
