Structural transformation and the oil price [PDF]

Review of Economic Dynamics, 2014
Abstract What part of the high oil price can be explained by structural transformation in the developing world? Will continued structural transformation in these countries result in a permanently higher oil price? To address these issues I identify an inverted-U shaped relationship in the data between aggregate oil intensity and the extent of ...
