Empirical evidence has been lacking to explain trade agglomerations over short distances. Starting with a novel micro-database of road freight shipments within Spain for the period 2003-2007, we break down city (municipal) trade flows into the extensive and intensive margins and assess trade...

We propose and apply a new theory-consistent algorithm, which uses disaggregated inter-city trade data to identify a pyramidic city system with central places and associated hinterlands. Because central places possess more industries than the cities in their hinterlands, and because industries,...

Large cities (central places) excessively export to smaller cities in their surrounding hinterland. Using Japanese inter-city trade data, we identify a substantial centrality bias: Shipments from central places to their hinterland are 50%-125% larger than predicted by gravity forces. This upward...

The conception of fuzzy central places (FCP), proposed by P. Em, made possible the understanding of the central functions' (CF) heterogenic distribution inside the urban agglomerations. The FCP is a bounded region of a set of points with CF. The correlation analysis proved a strong relation...

This paper examines whether population shrinkage leads to changes in the urban hierarchy in terms of relative sizes of cities and their functions onomic geography. We work backwards in a racetrack economy with eight cities in a long-run equilibrium. Initial distribution of population is chosen...

The optimization of the location of public services in the villages and neighborhoods in the city of Huambo in Angola results in a hierarchical system of central places that can be calibrated to give different hierarchies according to the accessibility level. This result is achieved for 300...

This paper explores the role of retailers as an urban amenity. Using data for Swedish rural and city municipalities for 2002-2008, "accessibility to shops" measures are constructed for the shops in the municipalities and in the hosting regions separately to examine the relationship between...
