The Journal of International Money and Finance recently published a special issue entitled “Understanding International Commodity Price Fluctuations” co-edited by Rabah Arezki (IMF), Prakash Loungani (IMF), Rick van der Ploeg (Oxford University), and Anthony J. Venables (Oxford University). The papers were presented at a conference in Washington, D.C., September 20-21, 2013, organized jointly by the Research Department of the International Monetary Fund and the Oxford Centre for the Analysis of Resource Rich Economies at the University of Oxford. The special issue addresses three key questions (i) Are commodity prices increasingly being driven by financial speculation?; (ii) Do newer techniques to forecast commodity prices beat a random walk? (iii) What are the economic and environmental impacts of new sources of energy supply?
