This paper estimates the relationship between agglomeration and multi factor productivity at the one digit industry level and by region using longitudinal firm level data for New Zealand. A key focus of the paper is on methods to represent firm level heterogeneity and non-random sorting of...

For transport systems the issues of pricing, service quality, funding and investment in urban areas are inextricably interdependent. The paper first argues that no policy can be set for any of these aspects of transport in isolation from any other. Transport planners and urban policy-makers can...

This paper assesses the differentiation between business centres in Britain using data on business location from the Census of Employment analysed at postcode district level. The paper uses a combination of micro-analytical, central place theory and interregional trade theory to argue that...

Although the productivity gains of urban agglomeration economies are generally found to be positive, there is a great deal of variability in the magnitude of reported estimates. This paper undertakes a quantitative review of the empirical literature on agglomeration through a meta-analysis of...

This paper explores the effects of road user charging throughout England. It develops a model to test charging scenarios including revenue raising and revenue neutral charging options, and economically efficient pricing. For each scenario we estimate effects on traffic volumes, user charges and...

The literature on land and property values demonstrates a great deal of variability in the estimated change in values arising from rail investments. This paper conducts a meta-analysis on empirical estimates from 23 studies (102 observations) that analysed the impact of rail on land/property...

This paper examines three key issues encountered when estimating the relationship between agglomeration and multi factor productivity (‘agglomeration elasticities’): the sorting of heterogeneous firms, the convexity of agglomeration effects, and the challenges of identifying the impact of...
