We exploit administrative data on exact commuting distances for a large sample of German employees and study the relation of commuting and wages. We find that it requires 1.5 times as much money in terms of higher wages for job changers to accept an increase of their commute as compared to their...

Coastal cities around the world are locales of high vulnerability. The issues are graver in the developing world where the challenges posed by the urbanisation and climate change multiply the existing risks. Here, we examine the case of Kochi, an Indian city located at the centre of a rapidly...

The intercity bus market in Germany was deregulated in 2013. As a consequence, there is now a dense network of intercity bus lines. For the first time, the German state-owned railway company Deutsche Bahn AG faces intermodal competition in public intercity passenger land transport on a large...

In this paper, we revisit the empirical observation that prices rise like rockets when input costs increase but fall like feathers when input costs decrease. The analysis draws on a novel dataset that include daily retail prices of gasoline and diesel from virtually all fuel stations in Germany...

This paper discusses the implications of autonomous-connected-electric-shared vehicles (ACES) for public finance, which have so far been widely ignored. In OECD countries, 5-12% of federal and up to 30% of local tax revenue are currently from fuel and vehicle taxation. The diffusion of ACES will...

We investigate the impacts of five airline mergers on one quality dimension, namely route frequency. We use monthly data on routes between the largest 64 US cities from 1999 to 2016. On average, the mergers decrease the frequency, but there are large differences between the five mergers. We...

We examine the relationship between the total size of an airline and its service quality by analysing over 4.8 million domestic flights within the USA in 2016. The total size of an airline is measured by its total market share, total amount of assets or total number of full-time equivalent...

The objective of the European railway reforms which started in the 1990s was to enable the entry of competition to raise the efficiency of railway transport. This was undertaken because the level of services, particularly in former Eastern Bloc countries, was very low due to neglected...

Infrastructure projects are increasingly aiming to improve liveability, in particular in urban areas. We analyse a specific case in which an existing highway in an urban area was moved underground in order to improve intercity traffic flows and to reduce traffic externalities. As travel times...
