Using time-varying BVARs, we find a substantial decline in the shortrun
price elasticity of oil demand since the mid-1980s. This finding
helps explain why an oil production shortfall of the same magnitude
is associated with a stronger response of oil prices and more severe
macroeconomic consequences over time, while a similar oil price
increase is associated with smaller output effects. Oil supply shocks
also account for a smaller fraction of real oil price variability in
more recent periods, in contrast to oil demand shocks. The overall
effects of oil supply disruptions on the US economy have, however,
