The Shale Oil Boom and the US Economy: Spillovers and Time-Varying Effects
SSRN Electronic Journal, 2019Co-Authors: Hilde C. Bjørnland, Julia ZhulanovaAbstract:We analyze if the transmission of Oil price shocks on the U.S. economy has changed with the shale Oil Boom. To do so, we put forward a framework that allows for spillovers between industries and learning by doing (LBD) over time. We identify these spillovers using a time-varying parameter factor-augmented vector autoregressive (VAR) model with both state level and country level data. In contrast to previous results, we find considerable changes in the way Oil price shocks are transmitted to the U.S economy: there are now positive spillovers to non-Oil investment, employment and production from an increase in the Oil price - effects that were not present before the shale Oil Boom.

The Shale Oil Boom and the U.S. Economy: Spillovers and Time-Varying Effects
2018Co-Authors: Hilde C. Bjørnland, Julia ZhulanovaAbstract:We analyze if the transmission of Oil price shocks on 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.

A Numerical Study on Stratified Shear Layers With Relevance to Oil-Boom Failure
Journal of Offshore Mechanics and Arctic Engineering, 2015Co-Authors: David Kristiansen, Odd M. FaltinsenAbstract:Interface dynamics of two-phase flow, with relevance for leakage of Oil retained by mechanical Oil barriers, is studied by means of a two-dimensional (2D) lattice-Boltzmann method (LBM) combined with a phase-field model for interface capturing. A multirelaxation-time (MRT) model of the collision process is used to obtain a numerically stable model at high Reynolds number flow. In the phase-field model, the interface is given a finite but small thickness, where the fluid properties vary continuously across a thin interface layer. Surface tension is modeled as a volume force in the transition layer. The numerical model is implemented for simulations with the graphic processing unit (GPU) of a desktop personal computer. Verification tests of the model are presented. The model is then applied to simulate gravity currents (GCs) obtained from a lock-exchange configuration, using fluid parameters relevant for those of Oil and water. Interface instability phenomena are observed, and obtained numerical results are in good agreement with theory. This work demonstrates that the numerical model presented can be used as a numerical tool for studies of stratified shear flows with relevance to Oil-Boom failure.

A Numerical Study on Stratified Shear Layers With Relevance to Oil-Boom Failure
Volume 8B: Ocean Engineering, 2014Co-Authors: David Kristiansen, Odd M. FaltinsenAbstract:Interface dynamics of two-phase flow, with relevance for leakage of Oil retained by mechanical Oil barriers, is studied by means of a 2D lattice-Boltzmann method combined with a phase-field model for interface capturing. A Multi-Relaxation-Time (MRT) model of the collision process is used to obtain a numerically stable model at high Reynolds-number flow. In the phase-field model, the interface is given a finite but small thickness where the fluid properties vary continuosly across a thin interface layer. Surface tension is modelled as a volume force in the transition layer. The numerical model is implemented for simulations with the graphic processing unit (GPU) of a desktop PC. Verification tests of the model are presented. The model is then applied to simulate gravity currents (GC) obtained from a lock-exchange configuration, using fluid parameters relevant for those of Oil and water.

Rural North Dakota's Oil Boom and Its Impact on Social Services
Social work, 2014Co-Authors: Bret Weber, Julia Geigle, Carenlee BarkdullAbstract:Over the last five years, North Dakota has experienced an Oil Boom based on high Oil prices and hydraulic fracturing technologies. This has brought economic expansion and population growth to rural communities that had previously experienced decades of depopulation and economic struggle. Although the state has enjoyed many benefits--especially in juxtaposition to a sluggish national economy--the Boom has also meant the arrival of economic refugees and dramatic impacts on largely rural social service systems. In the midst of a rapidly changing situation, available information tends to swing between euphoria over economic success and hysteria about rising crime and shifting cultures. In response, the authors used a primary focus group with county social service directors from across the state and a followup focus group with social workers operating on the edge of Oil activity. Grounded in resilience theory, qualitative analysis of the primary focus group, and triangulation of data from other sources, this study provides a more objective report of the housing and social challenges, the benefits of the Boom, and the challenges to solutions.
