The current dynamics in the Western European urban system are in marked contrast with the bourgeoning literature stressing the importance of agglomeration for economic growth. This paper explores whether this is due to the rise of 'city network economies', leading to processes of borrowed size as well as the rise of agglomeration shadows in networks of cities. The spread of metropolitan functions over Western European cities is analysed. It is found that network connectivity positively enhances the presence of metropolitan functions, but local size remains the most significant determinant for most types of functions. The importance of size and network connectivity differs across metropolitan functions and across cities. [ABSTRACT FROM AUTHOR]

This paper introduces the theme of the special issue 'Agglomerations and the Rise of Urban Network Externalities'. Urban network externalities are defined as external economies from which firms and households can benefit by being located in agglomerations that are well embedded in networks that connect with other agglomerations. The contributions focus on the conceptualization of urban network externalities and their influence on urban performance. Finally, a research agenda is presented, that should focus on multiplexity and heterogeneity in networks and their impacts; interrelations between agglomerations and networks and their dynamic and place-based nature; and, the policy implications of urban network externalities.
