This study tests distance weights based on the economic geography assumption of straight lines and the complex networks approach of empirical road segments in the Mexican system of cities to determine the best distance specification. We generated network graphs by using geospatial data and computed weights by measuring shortest paths, thereby characterizing their probability distributions and c...

BACKGROUND Neighborhood-level characteristics such as economic hardship and the retail food environment are assumed to be correlated and to influence consumers' dietary behavior and health status, but few studies have investigated these different relationships comprehensively in a single study. This work aims to investigate the association between neighborhood-level economic hardship, the retai...

Transport investments can induce positive productivity benefits via agglomeration economies by increasing the scale and efficiency of spatial economic interactions. In assessing the ‘agglomeration benefits’ of transport investments we need to understand the spatial scale over which these externalities are distributed. This report is concerned with the effect of urban agglomeration on productivi...
