Oil prices and economic activity in Greece

摘要

The paper studies the relationship between oil prices and economic activity in Greece during the period 1982:1-2008:8. Different empirical methods are used to estimate whether oil price changes affect asymmetrically the economic activity. A regime-switching model (RS-R) and a threshold regression modeling (TA-R) are applied which have the advantage to capture the dependence structure of the series both in terms of constant and variance. The empirical evidence suggests that the degree of negative correlation between oil prices and economic activity strengths during periods of rapid oil price changes and high oil price change volatility.
