Levers for Change? The Welfare Effects of a Large-scale Public Transport Subsidy in Germany 1: Potsdam Institute for Climate Impact Research (PIK), Germany; 2: University of Potsdam; 3: Institute of Labor Economics (IZA) Ever more countries consider reducing the cost of public transport to incentivize shifts to more sustainable transport modes. This paper quantifies the welfare effects of a large-scale, nationwide public transport subsidy in Germany - the so-called Deutschlandticket. We pair novel cellphone- and app-based mobility data from several European countries with recent advances in synthetic control methods to examine the impacts on mobility and external costs. Our findings show a persistent increase in train ridership and a substitution away from car travel (number of trips and kilometers driven). We find no evidence for latent demand as total mobility remains constant. The substitution is the largest in cities with high-quality public transit as well as for trips of longer distances. The implied CO2 emission reduction amounts to around 5.4 million tons per year (3.8% of total transport sector emissions). In line with our results on less road traffic, we also find suggestive evidence for reduced air pollution in cities (NO2 concentration), and lower road congestion (travel time per kilometer). | |
