GOLD, OIL AND THE EURO: HYPOTHESES AND TIME SERIES ANALYSIS A. G. Malliaris and Mary E. Malliaris Loyola University Chicago The Athenian Policy Forum and the Indian Institute of Management Kozhikode Conference, Calicut, India, December 18-20, 2008.
Outline General Comments About Gold, Oil and the Euro These Markets Prior to the Creation of the Euro How are these Markets Related Since the Creation of the Euro
Gold As an Anchor of the Gold Standard As a Hedge Against Inflation As a Free Commodity Since mid-1971
Long-Term Gold Price
Oil Significant Commodity in Global Economy Its role today is somehow lesser than in early 70s but still important Extremely volatile
Long-Term Oil Price
The Euro Start with the European Common Market in 1957 From a Customs Union to One Market One Market with One Currency
The Creation of the Euro
Daily Data since 1999
Hypotheses Do these 3 Markets follow Random Walks? The twin U.S. deficits weaken the dollar and strengthen the euro and induce oil producers to demand compensation. Increases in oil prices impact gold prices.
Time Series Methods Are the euro, oil and gold co-integrated? Are there any short- and long-term relationships between the euro, oil and gold?
Augmented Dickey-Fuller Tests of Stationarity The model is:
Price Level (LN(X)) Only LagsLags and Constant Lags, Constant, and Trend Gold No lags lags lags Oil No lags lags lags Euro No lags lags lags
First Price Differences (LN(X t ) - LN(X t-1 )) Only LagsLags and Constant Lags, Constant, and Trend Gold No lags lags lags Oil No lags lags lags Euro No lags lags lags
