Abstract: New technology is prone to disruptions. We examine the impact of a supply disruption that simultaneously reduces production capacity and increases operational costs by removing a relatively efficient capital asset. Specifically, we analyse the unexpected regulatory decision to ground the Boeing 737 MAX in 2019, Boeing’s most fuel-efficient narrow-body aircraft at the time. We use a difference-in-differences design, leveraging the differential exposure to the grounding, which we construct using novel data on flight frequency in the U.S. We observe heterogeneous price and cost effects across airlines. For Southwest, the airline most affected by the disruption, the price increase driven by fleet constraints is five times larger than the effect from rising operational costs. These findings show that when firms become capacity constrained due to a drastic reduction in the capital stock, then changes in the operational costs (related to efficiency) become marginal. Instead, the increase in prices will be primarily explained by operating with a diminished production capacity (i.e. less available fleet). Although not being the main relevant aspect for pricing, the change in operational costs have a social cost for society through a rise in emissions.

Abstract:  I develop a structural supply-and-demand model to explain how consumer heterogeneity influences prices and the pass-through rate of shocks to consumer welfare in the presence of environmental externalities. Using price data from the European aviation market following the introduction of per-passenger taxes, I evaluate the welfare effects of existing policies, focusing on costs to high- vs. low-income consumers. I simulate alternative taxation schemes (e.g., jet fuel taxes) and find that taxes have limited efficacy in internalizing externalities when considering only the "social cost of carbon." However, the policy's corrective value increases substantially when accounting for local pollutants (NOx, PM) and contrail formation.

Abstract: We investigate tax instruments for correcting vehicle pollution from both exhaust (CO2, NOx, etc.) and non-exhaust sources (wear-and-tear of brakes, tires, and roads) related to vehicle weight. Using detailed Norwegian registry data, we estimate a model of household driving and purchasing decisions to compare counterfactual tax regimes. We find that while registration taxes based on vehicle characteristics can approximate Pigouvian outcomes in competitive markets, market power complicates this: oligopoly markups already exceed social marginal costs, and corrective driving taxes may exacerbate distortions unless market power is addressed.
