This study analyzes the effects of binding speed limits on crash frequency on German motorways. Various geo-spatial data sources are merged to a new data set providing rich information on roadway characteristics for 500-meter segments of large parts of the German motorway network. The empirical...

This data report describes the first wave of the RWI Climate-Mobility Panel, a recurring household survey that aims in particular to investigate individual mobility behavior and preferences with regard to mobility-related policies. It further includes information on attitudes towards...

This paper analyzes whether the expansion of regional airports in Germany caused positive spillover effects on the surrounding economies, exploiting the deregulation of the European aviation market as a quasi-experiment. Such potential spillovers are often used as an argument for the substantial...

Despite steady increases in fuel economy, CO2 emissions from road transportation in Germany are on the rise, increasing by nearly 4% since 2009. This study analyzes the impact of different policy levers for bucking this trend, focusing specifically on the role of fuel prices and features of the...

To accelerate the electrification of the transport sector, many countries subsidize both the construction of public charging infrastructure and the purchase of electric vehicles (EVs). Possible complementarities between these measures raise the question of their optimal calibration. Drawing on...

Consumer subsidies are commonly employed to incentivize the purchase of battery electric vehicles (BEVs), but free-ridership potentially undermines their effectiveness. The present study investigates BEV subsidies in Germany, distinguishing their effect between company- and private cars. Drawing...

This paper reviews the book 'Infrastructure and Poverty in Sub-Saharan Africa' by Antonio Estache and Quentin Wodon. The authors summarize the political debate on infrastructure policy in Africa in a very compelling and knowledgeable way and make a convincing case for pro-poor subsidies. Yet,...

In addition to efficiency standards and consumer information, car-related taxes constitute one of three pillars of the European Commission’s strategy to reduce CO2 emissions from passenger cars.A longstanding question concerns the effectiveness of such taxes in determining the car-purchasing...

Air pollution has become an increasing health threat for the local population in many cities around the world. Using high resolution remote sensing data on nightlights and fine particulate matter (PM2.5) for the years 1998-2013, I study the contemporary nexus between city shape and air pollution...
