urbanization agglomeration that is named jacobs externalities, refers to the role of economic diversification in urban. localization agglomeration, marshal-arrow-romer (mar) externalities, is related to the concentration of firms activated in a special industry within a specified place. the purpose of this research is to explore the impact of different types of agglomeration economies on employ...

This paper analyzes the relationship among economic geography, fertility and migration. The empirical evidence presented reveals that persistent regional variations in fertility exist within a country and that regional total fertility rates are negatively related to regional population density. A two-period overlapping generations model of endogenous fertility, incorporating n-regions, agglomer...

Solubility of polysilane macromolecules has so far been a scientific as well as technological problem due to a lack of understanding of their proper molecular size and agglomeration/de-agglomeration conditions. Here we show that, in contrary to previous reports, the polysilane molecules are inherently small enough to be, under right conditions, dissolved. We used a dynamic light scattering and ...

A two-step technique based on micromechanical models is suggested to determine the influence of aggregated/agglomerated nanoparticles on Young's modulus of polymer nanocomposites. The nanocomposite is assumed to include nanoparticle aggregation/agglomeration and effective matrix phases. This method is examined for different samples, and the effects of important parameters on the modulus are inv...

This paper estimates the determinants of labour productivity and employment in European NUTS2 regions. We focus on technological capabilities (proxied by regional patents), agglomeration economies (employment density), and openness, proxied by the number of airplane passengers embarked and disembarked in the region. We employ 1989-1996 data drawn from the Eurostat REGIO data base. By using inst...

There are two independent strands of literature on the geographic distribution of economic activities. One is the new economic geography that emphasizes product diversity, and the other is probabilistic migration that stresses taste heterogeneity in residential location. This article incorporates these two characteristics into a single framework, and analyzes how they affect the number and stab...

This paper models the competition among jurisdictions for two firms in the same industry as a sequential auction. Before choosing a site, the firms solicit fiscal incentives from jurisdictions. In the presence of agglomeration economies, winning the first location contest makes a region more attractive for subsequent firms. The first firm receives a higher recruitment subsidy and the second fir...

Agglomeration can be caused by asymmetric information and a locational signaling effect: The location choice of workers signals their productivity to potential employers. The cost of a signal is the cost of housing at a location. When workers’ marginal utility of housing is negatively correlated with their productivity, skill-biased technological change causes a core-periphery bifurcation where...

Despite wide recognition of their significant role in explaining sustained growth and economic development, uncompensated knowledge spillovers have not yet been fully modeled with a microeconomic foundation. The main purpose of this paper is to illustrate the exchange of knowledge as well as its consequences on agglomerative activity in a general-equilibrium search-theoretic framework. Agents, ...

This paper focuses on the questions to what extent agglomeration effects and localized inter-organizational linkages influence different types of innovative performance of firms. Doing so adds to the relatively scarce firm-level literature regarding the role of regional environment for the innovative performance of firms by disentangling the often conflated effects of agglomeration effects and ...
