• The Role of Time-Varying Price Elasticities in Accounting for Volatility Changes in the Crude Oil Market

  Staff Working Paper 2011-28 Christiane Baumeister, Gert Peersman

  There has been a systematic increase in the volatility of the real price of crude oil since 1986, followed by a decline in the volatility of oil production since the early 1990s. We explore reasons for this evolution. We show that a likely explanation of this empirical fact is that both the short-run price elasticities of oil demand and of oil supply have declined considerably since the second half of the 1980s.
