We consider whether external urban economic advantages (agglomeration economies) vary with time and space using a simple economic model and detailed micro-data on 134 locations in New Zealand for the period 1976-2018. We find subtle temporal variation, with estimates peaking in 1991 and then...

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...

Concentration of immigrants and its associated externalities have become an important topic in contemporary international migration research, both from a methodological as well as an empirical perspective. The purpose of this paper is twofold. First, it aims to provide an overview of that part...

This paper reports the results of a stated preference study investigating the Willingness-to-pay (WTP) of employees at the Amsterdam Zuidas for the presence of non-shopping and shopping facilities. The Amsterdam Zuidas area, surrounding the current train-metro-tram station Amsterdam Zuid...
