A large body of literature considers the productive advantages of cities, or "agglomeration economies". Most empirical studies report positive agglomeration economies, although large variation exists in the magnitude of estimates. We use a meta-analysis to explore this variation, drawing on...

Using commuting data for Brisbane, Australia, we find that accounting for measurement error in travel times causes the magnitude of parameters in mode and location choice models to increase approximately three-fold and 30-40%, respectively. Errors appear to be somewhat systematic, with travel...

Using data for 134 locations in New Zealand, we study the effects of crime and agglomeration on urban amenity. We find that crime has significant negative effects on the value of urban amenity, with elasticities of approximately −0.06 for firms and −0.09 for workers. To put this effect in...

The paper develops an important spatial extension of longitudinal models. Longitudinal models capture variations in the timing of events. Recently, they have also been applied to variations in the spacing of events, using distance as a mathematical equivalent of time. Spatial relationships are,...

An increasing proportion of the oldest-old (85+) population, combined with a pronounced abundance of older women relative to older men, characterize the demographic development of industrialized countries. Both, aging and feminization, strongly influence the transportation demands of the future....
