Environmental Economics Brownbag Seminar

The Environmental Economics Brownbag Seminar series is a cooperation between Leibniz Centre for European Economic Research (ZEW) and the universities of Mannheim and Heidelberg. The seminar brings together environmental and resource economists from the whole metropolitan area as well as external speakers to present and discuss cutting edge work. It typically takes place once a month. Anyone interested in the topic  is welcome to attend.

Unless noted otherwise, all seminars take place at ZEW – Leibniz Centre for European Economic Research, Room HKH  (L7,1, 68161 Mannheim) or at FZU - Seminar Room 215 (Bergheimer Str. 20, 69115 Heidelberg). If you have questions or are interested in joining a seminar, please send an email to one of the organizers:

Title: The Welfare Effects of Climate Policies for Global Aviation

Abstract: We study the question of climate policy performance under different degrees of market power using the example of the global aviation market. In contrast to most other studies we go beyond an assessment of specific (geographical) markets or specific policies. We develop a spatial, general equilibrium model of the global aviation market that allows us to model different degrees of market power, ranging from perfect competition to a Cournot oligopoly. We assume that airlines have two channels to abate carbon emissions. The first is by reducing the number of transported passengers and the second is through a fuel switch from conventional jet fuel to sustainable aviation fuel (SAF). Using a granular dataset on booking numbers and prices, we take the model to the data. We analyze the welfare, market and environmental effects of policies that contribute to the decarbonization of global aviation and incentivize the adoption of sustainable aviation fuels. Our results suggest that, as expected, in an undistorted market with perfect competition, emissions pricing under a cap reduces welfare less than reaching the same emissions target via a SAF quota. The opposite is true under a Cournot oligopoly, where the SAF quota performs better. Studying the current, geographically asymmetric regulatory measures shows that strict EU regulation puts a strain on the local population and on local airlines that lose market power when competing á la Cournot. We also find that the current regulatory measures will not be sufficient to truly decarbonize the global aviation market.


Everyone interested is welcome to attend.
