Rail cost function analysis has been a popular topic in the (empirical) economics literature over the past decades. Most studies find increasing returns to density for rail companies. The results can, however, be quite diverse. Results for the Dutch National Railway company (NS), for instance,...

Knowledge drives the growth of nations and regions in a competitive space-economy. Hence, we would expect a strong correlation between investments in R&D, knowledge and learning processes, on the one hand, and productivity increases, on the other. However, the empirical evidence shows consistent...

Productivity across European regions is related to three types of networks that mediate R&D-related knowledge spillovers: trade, co-patenting and geographical proximity. Both our panel and instrumental variable estimations for European regions suggest that network relations are crucial sources...

In a circular city model, I consider network design and pricing decisions for asingle fast transport connection that faces competition from a slower but betteraccessible transport mode. To access the fast transport network individuals haveto make complementary trips by slow mode. This fact has...

A burgeoning literature has emerged during the last two decades to assess the economic impacts of immigration on host countries. In recent years much research has been at the national level under the assumption that impacts in open regions may dissipate through adjustment processes such as...

Data Envelopment Analysis (DEA) has become an established approach for analyzing and comparing efficiency results of corporate organizations or economic agents. It has also found wide application in comparative studies on airport efficiency. The standard DEA approach to comparative airport...

This paper analyses the cost of access travel time variability for air travelers. Reliable access to airports is important since it is likely that the cost of missing a flight is high. First, the determinants of the preferred arrival times at airports are analyzed, including trip purpose, type...

Existing work emphasizes the importance of traffic congestion externalities, but typically ignores cruising-for-parking externalities. We introduce a novel methodology to estimate the marginal external cruising costs of parking. The level of cruising is identified by examining to what extent the...
