The Shale Oil Boom and the U.S. Economy: Spillovers and Time-Varying Effects
MetadataShow full item record
We analyze if the transmission of oil price shocks in the U.S. economy has changed as a result of the shale oil boom. To do so we allow for spillovers at the state level, as well as aggregate country level effects. We identify and quantify these spillovers using a factor-augmented vector autoregressive (VAR) model, allowing for time-varying changes. In contrast to previous results, we find considerable changes in the way oil price shocks are transmitted: there are now positive spillovers to non-oil investment, employment and production in many U.S. states from an increase in the oil price - effects that were not present before the shale oil boom.
