We propose two model-based measures of the intensity of local and global agglomeration patterns at the industry level. Spatial plant dispersion in a given industry is modeled as the outcome of an error components process that provides a convenient framework for the simultaneous treatment of...

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 paper investigates the impact of labor markets and economies of agglomeration on firms location. We show that the existence of a lower bound on wage (e.g. a minimum wage or a reservation wage) introduces asymmetric location of firms. Moreover, changes in that lower bound or in global...

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 analyzes the early development of new establishments evaluating the role of spatial selection and agglomeration. The analysis shows a clear and strong selection of more productive new establishments into larger regions, regardless of the foundation type. While at the end of the...

Departing from research on expanding, high-technology industries, we study the impact of agglomeration in a declining, low-technology industry. The setting is U.S. footwear manufacturing between 1975 and 1991, when import competition rendered local support critical for survival. We examine how...

This study explores the relationship between agglomeration economies and industrial productivity between 1980 and 2010 in Ecuador. The measure of productivity used is labour productivity. We conclude that urbanization economies have a positive impact on productivity in the period analyzed.
