The following interview with Prof. James Hamilton was conducted in September 2022 by Dr. Fredj Jawadi with the assistance of Professor Adonis Yatchew in association with the 6th International Workshop on Financial Markets and Nonlinear Dynamics (FMND) held in Paris, France. The interview includes 20 questions related to commodity price dynamics. The aim of the discussion was, first, to help readers gain a better understanding of the factors driving commodity price volatility during the COVID-19 pandemic. Second, we analyzed commodity reactions to the ongoing Ukrainian war. Third, we examined the impact of changes in commodity prices on the economy as a whole and on inflation in particular. Finally, we discussed projections related to the dynamics of commodity prices in the future and the impact on the energy transition process. We hope that this interview will give readers clearer insights into the causes and consequences of commodity price changes and their evolution over time.
