Copper nanoparticles have been deposited on silicon surfaces by a simple galvanic displacement reaction, and rapid thermal annealing has been performed under various atmospheric conditions. In spite of the general tendency of the agglomeration of nanoparticles to lower the surface energy at elevated temperatures, our plan-view and cross-sectional transmission electron microscopy (TEM), energy d...

The purpose of this article is twofold. First, we present an alternative model of agglomeration and trade that displays the main features of the recent economic geography literature while allowing for the derivation of analytical results by means of simple algebra. Second, we show how this framework can be used to permit (i) a welfare analysis of the agglomeration process, (ii) a fullfledged fo...

This paper uses a micro data set on auxiliary establishments from 1977 to 1997 in order to investigate the determinants of headquarter agglomerations and the underlying economic base of many larger metro areas. The significance of headquarters in large urban settings is their ability to facilitate the spatial separation of their white collar activities from remote production plants. The results...

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...

In contrast to what several papers have argued recently, we show that firm heterogeneity fosters agglomeration of economic activity. If firms are more similar with respect to their total factor productivity, each company faces a lower propensity to export. This renders the home market more important speaking against agglomeration. We also relate changes in firm heterogeneity to technological pr...

This paper investigates trends and determinants of the spatial concentration of China’s manufacturing industries using a large firm-level data for the time period of 1998 to 2005. It is found that the overall industrial agglomeration in China has increased steadily in recent years though it is still much lower than those of the well-developed market economies (such as United States, United King...

This paper provides a survey and guide to the literature relevant to urbanization and economic development. The paper starts with some basic facts and trends about urbanization worldwide. It then reviews the traditional twosector urban-rural model, but focuses on the modern version, Krugman’s coreperiphery model. However, two sector models do not capture the notion of an economy composed of man...

The influence of post deposition annealing (PDA) up to temperatures of TPDA=900°C on the morphology and agglomeration behavior of ambient temperature sputter deposited platinum onto anodic aluminum oxide templates is investigated. Both cluster agglomeration and diffusion processes occur on the surface and on the inner channel walls. When the annealing temperature is less than 400°C, particles a...

We examine the impacts of agglomeration economies on the location of Foreign Direct Investment (FDI) in Vietnam. Using a large dataset that provides detailed information about individual firms, we investigate the location choices by 920 newly created foreign firms in 2009 in about 125 different 4-digit industries. The estimates of the conditional logit model show that agglomeration benefits mot...
