One of the main unanswered questions in the field of urban economics is to which extent subsidies to public transit are justified. We examine one of the main benefits of public transit, a reduction in car congestion externalities, the so-called congestion relief benefit, using quasi-natural...

We account for endogeneity of distance by...</p></a>

According to theory, the effect of carriers' transport costs on freight prices depends on the directional imbalance in transport flows. Using data on inland waterway transport, we demonstrate that when the ratio of export to import trips doubles, the marginal effect of carriers' transport costs...

This discussion paper led to a publication in <I>Empirical Economics</I> 2013, 45(3), 1189-1204.<P> We analyse the effects of distortionary company car taxation through increased household carownership for the Netherlands. We use several identification strategies and demonstrate thatfor about 20 percent...</p></i>

For certain goods, higher levels of congestion imply higher levels of expected future entry costs. This provides current users of the good with an incentive to hoard, that is, to lengthen their duration of good use, in order avoid entry costs later on. We test for hoarding of university...

This paper presents an approach for the estimation of welfare effects of tax policy changes under heterogeneity in consumer preferences. The approach is applied to evaluate the welfare effects of current tax advantages for electric vehicles supplied as fringe benefits by employers. Drawing on...

According to theory, the effect of carriers' transport costs on freight prices depends on the directional imbalance in transport flows. Using data on inland waterway transport, we demonstrate that when the ratio of export to import trips doubles, the marginal effect of carriers' transport costs...

The market for commercial properties is characterised by extreme heterogeneity in demand. In this paper, we aim to gain more insight in the heterogeneity in demand for employment agglomeration and size of the rental property using a two-stage hedonic approach following Bajari and Benkard (2005)....

This paper examines the effects of specialisation (within-sector clustering) and diversity (between-sector clustering) on business services profitability and location choice. We apply a semiparametric Poisson sorting model allowing for firm-specific effects. We find that for most firms,...

There is little known about the effects of staggered-hours programs that affect workers' working schedules to mitigate peak congestion. We examine the effect of workers' morning start times on their wages for Germany. In contrast to previous work based on cross-section data, we demonstrate that...
