  1. An inexact science
    accounting for measurement error and downward bias in mode and location choice models
    Author: Donovan, Stuart; Graaff, Thomas de; Groot, Henri L. F. de

    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... more

    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 times being underestimated for short journeys and vice versa for long journeys-especially by public transport. We find similar results when we use alternative transport cost measures and independent commuting data from London. Our findings are likely to have important implications for transport and land use policy as well as the many types of economic models in which travel times-and transport costs, more generally-occupy a central role.

  2. An urban overhead?
    crime, agglomeration, and amenity
    Author: Donovan, Stuart; Graaff, Thomas de; Groot, Henri L. F. de; Schiff, Aaron
    Published: [2023]

    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... more

    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 context, this implies the value of urban amenity for workers is approximately 2-3 times more sensitive to crime than average temperature. More uniquely, we find that controlling for crime leads to somewhat larger estimates of agglomeration economies. Together, these results suggest that crime detracts significantly from the value of urban amenity and may also act as an urban congestion cost that serves to undermine agglomeration economies.

    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 falling over the next 15-years by approximately 1%. Since 2006, however, estimates have remained broadly stable. Our results reveal more significant spatial variation: Large cities offer net benefits in production, but not in consumption, whereas small locations close to large cities ("satellites") experience agglomeration economies that are stronger than average.

    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 6,684 estimates from 295 studies that cover 54 countries and span six decades. Using rich data and robust methods, we unify and extend earlier reviews. For our preferred combination of study attributes, we find agglomeration elasticities are likely to lie in the range 2.7-6.4%. Our findings confirm the controls enabled by detailed data give rise to smaller estimates. We also document several trends, with overall estimates rising from 1980-2000 and then falling. Estimates for manufacturing sectors, in contrast, fell for the entire six decades covered by our data. We speculate on possible causes of these trends, such as urban congestion, technological shocks, freight costs, and regulatory settings.
