Eine Maßnahme, die häufig als geeignet zur Minderung der Schadstoffkonzentrationen in den Städten genannt wird, ist die Umweltzone (UWZ). Mit diesem Instrument sollen stärker Schadstoff emittierende Kfz aus den Zonen herausgehalten und eine beschleunigte Umstellung der Fahrzeugflotte hin zu...

The aim of the project "Implementation and further development of the GLI:X - Green Logistics Indicators in South Africa" was to build on the results and successes achieved in the previous GLI:X projects I-II and to further develop and apply the GLI:X indicator system developed within the...

Mobilität ist eine zentrale Voraussetzung, um am gesellschaftlichen Leben teilzunehmen und liefert einen wesentlichen Beitrag zu einer hohen Lebensqualität. Gleichzeitig ist der städtische Personen- und Güterverkehr ein Hauptverursacher von Luftverschmutzung, Lärm und Flächenverbrauch....

We estimate an equilibrium model of residential sorting with endogenous traffic congestion to evaluate the efficiency and equity impacts of urban transportation policies. Leveraging fine-scale data on household travel diaries and housing transactions with home and work locations in Beijing, we...

In cities worldwide, the widespread use of single occupancy cars often leads to traffic congestion and its associated ill effects. Using high frequency data from Google Maps, we test whether high-occupancy vehicle (HOV) policies can be an effective tool to combat congestion. Using the unexpected...

We characterize optimal urban transportation policies in the presence of congestion and environmental externalities and evaluate their welfare and distributional effects. We present a framework of a municipal government that implements different transportation equilibria through its choice of...

We develop novel estimates of peak and off-peak price elasticities for urban mass transit demand in San Francisco using a large natural experiment with 3.6 million trip sessions and a natural field experiment that both have exogenous price subsidies. We then estimate the welfare impacts for...

Will politics lead to over-building or under-building of transportation projects? In this paper, we develop a model of infrastructure policy in which politicians overdo things that have hidden costs and underperform tasks whose costs voters readily perceive. Consequently, national funding of...
