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...

Standard approaches to studying industrial agglomeration have been in terms of scalar measures of agglomeration within each industry. But such measures often fail to distinguish spatial scales of agglomeration. In a previous paper, Mori and Smith (2014) proposed a pair of quantitative measures...

This paper analyzes the effects of local externalities on the probability of starting a new economic activity. We use firm-level data and geographic information on French zip-codes for 1993-2002. Poisson and Negative Binomial panel data models are estimated as they naturally allow for large sets...

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...

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...

During the last year, the research field of spatial economic has rapidly increased. There is consensus thatthe economic performance of a region depends not only on its own potential, but also on the development of their neighbouring regions. Knowledge spillovers, which are non constant over...

Using a simplified NEG model, we investigates the relation between labor diversity and agglomeration. In the theoretical part, we assume the following two-region model. Homogenous consumption goods are produced using a constant returns technology with homogenous capital and heterogenous workers....

During the last year, the research field of spatial economic has rapidly increased. There is consensus that the economic performance of a region depends not only on its own potential, but also on the development of their neighbouring regions. Knowledge spillovers, which are non constant over...

Using a generalized version of the Venables (International Economic Review, 37: 341-359) model, this article explores the relative locations of two vertically linked sectors with knowledge spillovers. Analytical investigation shows that the dynamic properties of the Venables model are...

In this paper, we derive and estimate a New Economic Geography model for the Colombian departments.2 We first derive an econometric specification relating wages to a distance weighted sum of the volumes of economic activities of the surrounding locations. Them, we test our econometric...
