Firm agglomeration is positively correlated with productivity, and it exhibits significant heterogeneity across industries. Yet, the connection between agglomeration and corporate investment remains underexplored. We develop a model of information sharing which predicts that knowledge-intensive...

This paper examines the industry-specific attenuation speed of agglomeration economies and its interplay with the large presence of state-owned enterprises in China. We achieve this focus by taking advantage of unique geo-coded administrative data on the universe of Chinese manufacturing firms....

Regions with high population agglomeration have always been important centers of growth throughout history. However, little is known about the economic spillovers an agglomerated region produces on its neighboring areas. In this paper, I look at the effect of growth of an agglomerated county on...

This paper uses a comprehensive source of yearly data to study private-sector labor demand across US counties during the past five decades. Our focus is on how employment levels and earnings relate to population density - that is, how labor markets in rural areas, suburbs, and cities have fared...

The article explores regional policy issues at the nexus of economic geography and the recent academic literature on the political economy of digitalization. The objective is to blend these two areas of research to derive a first set of preliminary policy implications for so called "Smart...

This review discusses frontier topics in economic geography as they relate to firms and agglomeration economies. We focus on areas where empirical research is scarce but possible. We first outline a conceptual framework for city formation that allows us to contemplate what empiricists might...

This work explores the spatial distribution of productive activities in the Italian manufacturing industry. We propose an econometric model which tries to disentangle locationspecific from sectoral drivers in the dynamic process of spatial agglomeration. The basic idea is that the former...

This paper proposes a model of urban agglomeration in conjunction with imperfect competition and endogenous product R&D of firms. The quality of differentiated manufacturing goods is a result of R&D services provided by research firms. Sectoral interactions are subject to spatially dependent...

We consider an economy in which a heterogeneous population of agents have to choose among a common set of alternatives. The utilities associated to the different alternatives posses a common component and an individual component, which reflect differences in the underlying structure of agents...

This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the conceptual distinctions between invention and innovation. We then describe how these factors are frequently measured in the data and some resulting empirical regularities....
