The German eco tax and its impact on CO2 emissions
Energy Policy, 2021Many countries have only recently introduced carbon taxation to reduce emissions and the time series data for evaluating these policies is not available yet. Consequently, we use the imposition quasi-carbon-taxes in the German transportation sector, i.e.

Airlines' cooperation in the US domestic market: Measuring the evolution of price gaps
Transportation Research Part A: Policy and Practice, 2022We follow up Ito and Lee (2007)’s research on the effect of alliances on air tickets prices for the US domestic market. Our main goal is to check if price differentials of allied and or codeshared products are maintained in the recent years.
