The Vehicle Scheduling Problem (VSP) is a well-studied combinatorial optimization problem arising for bus companies in public transport. The objective is to cover a given set of timetabled trips by a set of buses at minimum costs. The Electric Vehicle Scheduling Problem (E-VSP) complicates...

Das Neun-Euro-Ticket war eines der größten Verkehrsexperimente der letzten Jahrzehnte. Was hat dieses Experiment bewirkt? Um dies zu beantworten, wurde die vierte Panel-Welle von repräsentativen Befragungsdaten ausgewertet, die im Rahmen des Projekts MOBICOR ("Mobilität in Zeiten der...

We examine whether a disclosure mandate for greenhouse gas emissions creates stakeholder pressure for firms to subsequently reduce their emissions. For UK-incorporated listed firms such a mandate was adopted in 2013. Using a difference-in-differences design, we find that firms affected by the...

Current corporate disclosures regarding carbon emissions lack commonly accepted accounting rules. The accrual accounting system for carbon emissions described here is grounded in the rules of historical cost accounting for operating assets, enabling the preparation of balance sheets and flow...

The public policies on mass transit and other economic policies have been unable to avoid increasing mass transit costs and urban bus fares, which places a burden on a majority of the population depending on public transit. This study analyzes the variations in urban bus fares and households...

The transport economics literature has indicated that introduction of competition for the market in urban bus services (i.e. by means of competitive bidding) could promote cost-efficiency with low fares and better quality services. Therefore, this paper analyse the main outcomes and the latest...
