An article by Reuters columnist John Kemp looks at a recent study written by economists Vladimir Filimonov (ETH Zürich), David Bicchetti (UNCTAD), Nicolas Maystre (UNCTAD), and Didier Sornette (ETH Zürich). Two of them, David Bicchetti und Nicolas Maystre, wrote an article which was published here at Flassbeck Economics on 5 February 2013 and which also looks at commodities as an asset. More research from 2011 on the subject by both of them can be found at UNCTAD’s homepage. Finally I have written a short article in German dealing with the topic of speculation in commodities.
