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,...

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...

In binary discrete regression models like logit or probit the omis- sion of a relevant regressor (even if it is orthogonal) depresses the re- maining <font face="Symbol">b</font> coefficients towards zero. For the probit model, Wooldridge (2002) has shown that this bias does not carry over to the effect of the regressor...

This paper addresses the issue of technogenesis and its geographical pattern. It aims to offer both a general analysis framework and a test on innovation data from several European cities. This framework is mainly built on the product life-cycle and the incubation approach. On the basis of this...

Industrial sites cause several negative externalities, such as traffic noise disturbance, congestion, and obstruction of view. In order to quantify the negative effects stemming from industrial sites, we estimate – using a hedonic pricing model – the impact of distance to industrial sites on...

Existing indices measuring the spatial distribution of economic activity such as the Krugman Specialisation Index, the Hirschmann-Herfindahl index and the Ellison-Glaeser index typically do not take into account the spatial structure of the data. In this paper, we first consider traditional...

Contemporary European urban planning policies aim to mix land uses in compact neighbourhoods. It is presumed that mixing land uses yields socio-economic benefits and therefore has a positive effect on housing values. In this paper, we investigate the impact of mixed land use on housing values...

Theoretical models on the selling process in the housing market are scarce. Taylor (1999) specifies a model where time-on-the-market gives a quality signal of the house to potential buyers if inspection outcomes of the house are not public. We specify a duration model with competing risks, where...

Information and Communication Technologies (ICT) have become important tools to promote a variety of public goals and policies. In the past years much attention has been given to the expected social benefits from deploying ICT in different fields (transportation, education, public participation...

This paper offers both a conceptual and an operational model that aims to map out the causes and implications of ICT perceptions and views of urban policy makers and/or administrative officials (denoted as urban front liners). This is followed by the presentation of an opera- tional path model,...
