TLDR
In this paper, a simple model of process innovation is proposed, where firms learn about their ideal production process by making prototypes and switch to mass-production and relocate to specialised cities with lower costs.Abstract:
A simple model of process innovation is proposed, where firms learn about their ideal production process by making prototypes. We build around this a dynamic general equilibrium model, and derive conditions under which diversified and specialised cities coexist. New products are developed in diversified cities, trying processes borrowed from different activities. On finding their ideal process, firms switch to mass-production and relocate to specialised cities with lower costs. When in equilibrium, this configuration welfare-dominates those with only diversified or only specialised cities. We find strong evidence of this relocation pattern in establishment relocations across French employment areas 1993u1996.read more

Urban Evolutions: The Fast, the Slow, and the Still
TL;DR: In this article, the authors provided evidence about the rapid location changes of industries across cities and showed that cities are also slowly moving up and down the urban hierarchy, while the size distribution of cities is skewed to the right and very stable.

The Divergence of Human Capital Levels across Cities
TL;DR: In this article, the authors present a model where the clustering of skilled people in metropolitan areas is driven by the tendency of skilled entrepreneurs to innovate in ways that employ other skilled people and by the elasticity of housing supply.

Cities and development
TL;DR: This paper starts with a “primer” on what the authors know about the conceptual and empirical links between development and urbanization, and investigates the evolution of spatial income inequality under massive rural-urban migration.

Skills in the city
TL;DR: This article found that large cities are more skilled than small cities, but only to a modest degree, and that cognitive and physical skills and physical strength are not rewarded to a greater degree in large cities.

Agglomeration and Regional Growth
TL;DR: In this paper, the authors review the theoretical links between growth and agglomeration and show that growth, in the form of innovation, can be at the origin of catastrophic spatial aggregation in a cumulative process a la Myrdal.

The Economy of Cities
TL;DR: In this article, the authors studied the economy of cities and the main social problems that humanity has and the greatest source of creativity, innovation and development opportunities to solve those problems, which is relevant for a number of reasons: first of all, because most of the planet's population is grouped in them.

TL;DR: In this paper, the authors used a new data set on the growth of large industries in 170 U.S. cities between 1956 and 1987 and found that local competition and urban variety, but not regional specialization, encourage employment growth in industries.

Innovation in cities: Science-based diversity, specialization and localized competition
TL;DR: In this article, the authors consider the effect of the composition of economic activity on innovation and test whether the specialization of economic activities within a narrow concentrated set of activities is more conducive to knowledge spillovers or if diversity, by bringing together complementary activities, better promotes innovation.
