Some products need several separate suppliers, each providing a different part. In those cases, every supplier holds some power over price, and that can raise costs along the whole supply chain.

What they work on
- Measure how shocks to electricity demand, generating costs, coal mining and railroads pass through to coal and transport prices, using reduced-form econometrics on confidential shipment and purchase data, interpreted with Cournot and Spulber models.
- Estimate a static structural model of the coal supply chain and power plant output to quantify supplier and downstream market power and simulate subsidy changes and industry consolidation.
- Test whether coal and transport prices reflect efforts to influence future market structure, such as delaying coal plant retirements, using a dynamic model and stylized counterfactual simulations.
More about the research
Coal-fired electricity is a clear example: power plants need both coal from mines and railroad transport to move it. This project studies how efficient the U.S. coal supply chain has been over the past thirty years, when complementary suppliers like these may have market power.
Why it matters
Coal supply chains that link mines, railroads and power plants shape electricity costs. Measuring how market power among complementary suppliers affected efficiency, and simulating subsidies for non-fossil energy, mergers and plant retirements, could inform regulators and policymakers on energy markets and competition. The methods could also be applied to other industries.
