Research Topic:
Export Demand Shock and Vertical Integration

Research Details:
We ask how export demand shocks affect vertical integration using a natural experiment in the US coal mining industry. Our identification strategy leverages an exogenous increase in demand due to the unintended consequences of modifications to European environmental policy. This triggered an increase in demand for high-sulfur coal but had no effect on low-sulfur coal. Using difference-in-difference estimations we study the organizational effects of the demand shock by comparing the evolution of vertical integration within treated mines compared to control mines. Consistent with the theoretical predictions we find a 14% increase in the probability that a treated mine is vertically integrated. A number of robustness and falsification exercises confirm the findings. The evidence provides support for nascent OIO theories that emphasize the role of market forces in determining equilibrium ownership structure.
