Abstract: A threefold analysis of commodity prices is carried out to observe their long-runbehaviour, their short-run properties and the main determinants. According to theevidence, the Prebisch-Singer hypothesis does not seem to be a property of mostprices. The cycles of commodity prices are asymmetric but contrary to the case ofeconomic activity, the longer phase corresponds to slumps. Interest rates seem tomaintain a negative relationship with commodity prices.

Keywords: commodity prices; real interest rates; Prebisch-Singer hypothesis; short-run behaviour. (search for similar items in EconPapers)
