Severe traffic congestion is ubiquitous in large urban centers, especially those in middle-income countries and emerging markets. Using road pricing as the first-best policy to address congestion has been drawing increased attention from policy makers. This paper provides the first causal...

In this paper, we construct commuters’ travel-time profiles, namely, the menu of travel times that each individual will likely face according to alternate trip timing choices, to measure congestion delays for morning commutes in California and explore a new trip scheduling pattern of commuters...

Many governments subsidize regional rail service as an alternative to road traffic. This paper assesses whether increases in service frequency reduce road traffic externalities. We exploit differences in service frequency growth by procurement mode following a railway reform in Germany to...

We study the short-term effects of the 9-Euro-Ticket, a major German public transport subsidization program, on particulate matter (PM). Using hourly PM readings from pollution monitoring stations throughout Germany, provided by the German Federal Environmental Agency, we find declines in...

It is widely accepted that the costs of under-pricing energy are large, whether in advanced or developing countries. This paper explores how large these costs can be by focussing on the size of the external effects that energy subsidies in particular generate in two important sectors - transport...

In Germany, competitive franchising is increasingly being used to procure passenger railway services that were previously provided by a state monopolist. This paper analyzes 77 tenders that differ with respect to network size, service frequency, contract duration and the proximity to other lines...

This paper investigates empirically the consumer demand of environmentally relevant goods for Germany, as well as their relationship to the demand for leisure. Higher prices for energy goods like gas, electricity or fuel oil due to higher indirect taxation amongst others may have serious welfare...
