Modelling and Forecasting Oil Prices: The Role of Asymmetric Cycles
نویسندگان
چکیده
We propose a new time series model aimed at forecasting crude oil prices. The proposed specification is an unobserved components model with an asymmetric cyclical component. The asymmetric cycle is defined as a sine-cosine wave where the frequency of the cycle depends on past oil price observations. We show that oil price forecasts improve significantly when this asymmetry is explicitly modelled.

متن کاملInvestigating the impact of real effective Dollar rate on OPEC oil prices: non-linear asymmetric cointegration approach
The oil price and the real effective exchange rate (REER) are two important variables affecting OPEC countries politics and economy. Despite the fact that the existing theoretical literature confirms the relationship between oil price and the exchange rate (Dollar), there is no consensus about the direction of causality between these two variable. Also, statistical data shows that there is a sy...
متن کاملThe Asymmetric Cycling of U.S. Soybeans and Brazilian Coffee Prices: An Opportunity for Improved Forecasting and Understanding of Price Behavior
The behavior of agricultural commodity markets can arguably result in markedly asymmetric price cycles, that is, downward cycles of substantially different length and breadth than upward cycles. This study assesses whether asymmetric-cycle models can enhance the understanding of the dynamics and provide for a better forecasting of U.S. soybeans and Brazilian coffee prices. The forecasts from as...
متن کاملForecasting Crude Oil prices Volatility and Value at Risk: Single and Switching Regime GARCH Models
Forecasting crude oil price volatility is an important issues in risk management. The historical course of oil price volatility indicates the existence of a cluster pattern. Therefore, GARCH models are used to model and more accurately predict oil price fluctuations. The purpose of this study is to identify the best GARCH model with the best performance in different time horizons. To achieve th...
متن کاملAsymmetric Impact of Oil Prices, Foreign Direct Investment and Economic Growth on Carbon Emissions in Iran: Evidence from the NARDL Approach
The amount of environmental pollution can be caused by several factors. These factors are not in the same position in terms of importance and impact, and not all of them can necessarily be seen together in one place or time. Therefore, the main purpose of this study is to investigate the asymmetric impact of oil prices, foreign direct investment and economic growth on carbon emissions in Iran d...
