Abstract

We estimate the Anderson and van Wincoop model of trade by using the data on the bilateral export flows from 26 Turkish regions to 180 countries for the years 2002 through to 2010. Regional transportation and communication infrastructure capacity, the positioning of point infrastructure in a region, and geography are explicitly accounted for. Our results highlight that land infrastructure, air transport capacity, and private maritime infrastructure presence, together with the distance of regional economies to exit nodes such as ports and airports, are important determinants of export performance. Based on our preferred regression where multilateral resistance terms are accounted for, we estimate that increases in the current land infrastructure, air transport capacity, and number of private ports of 1 per cent increases exports approximately by 0.38 per cent, 0.14 per cent, and 0.045 per cent respectively.

Abstract

In order to understand patterns of urban commuter flows, insight is required into urban spatial structure (and vice versa). The present contribution first provides a concise overview of the theoretical perspectives from which economists and geographers approach commuting issues. Subsequently, the focus shifts to the classical spatial-economic urban models and how they explain commuter movements. We conduct a number of cluster analyses from which we are able to derive a commuting typology of city region areas. We conclude that distance (which also comprises journey time and proximity of traffic infrastructure), housing characteristics, housing environment, and income continue to play key roles in commuting patterns in the metropolitan areas under consideration.
