The standard approach to studying industrial agglomeration is to construct summary measures of the degree of agglomerationʺ within each industry and to test for significant agglomeration with respect to some appropriate reference measures. But such summary measures often fail to distinguish...

This paper proposes a simple method measuring spatial robustness of estimated coefficients and considers the role of administrative districts and regions' size. The procedure, dubbed "Grid and Shake", offers a solution for a practical empirical issue, when one compares a variables of interest...

This study investigates whether services sectors’ agglomeration can be explained within a common New Economic Geography model by Krugman and Venables (1996). Special feature of this modeling is to account for the lower importance of intermediate goods received for the services sector, a fact...

Ellison and Glaeser's (1997) index of geographical concentration distinguishes between natural advantages and spillovers as a source of industrial agglomeration, but the well-known 'observational equivalence' means little is known about the relative importance of these. This paper uses the...

This paper explores how the interaction between firm heterogeneity, urban costs and transport costs determines spatial configuration across regions within a simple general-equilibrium model. We spot light on how firm heterogeneity affects the centrifugal and centripetal forces and reshapes the...

A prominent feature of economic geography in America is the positive correlation amongst local incomes, housing costs and city population. This paper embeds a "black box" agglomeration economy within a more neoclassical general equilibrium model of local wages, rents and population to assess the...

This study empirically establishes a link between medieval trade, agglomeration and contemporary regional development in ten European countries. It documents a statistically and economically significant positive relationship between prominent involvement in medieval trade and commercial...

We examine "agglomeration shadows" that emerge around large cities, which discourage some economic activities in nearby areas. Identifying agglomeration shadows is complicated, however, by endogenous city formation and "wave interference" that we show in simulations. We use the locations of...
