The ethnic composition of US inventors is undergoing a signi…cant transformation — with deep impacts for the overall agglomeration of US innovation. This study applies an ethnic-name database to individual US patent records to explore these trends with greater detail. The contributions of Chinese and Indian scientists and engineers to US technology formation increase dramatically in the 1990s. ...

Palm kernel shell is an important bioenergy resource in Thailand. However, due to elevated alkali content in biomass ash, this oil palm residue shows high tendency to bed agglomeration in a fluidized-bed combustion system using conventional bed material (silica sand). In this study, palm kernel shell was burned in the conical fluidized-bed combustor (FBC) using alumina and dolomite as alternati...

OBJECTIVES The aim of this paper is to identify the factors that determine the environmental domain of quality of life in economically active adults living in the industrial agglomeration in Poland. MATERIALS AND METHODS During the cross-sectional epidemiological study conducted among the economically active population aged 45-60, we used a short version of the WHOQOL-BREF questionnaire. Resp...

Geographically concentrated industry activity creates pools of skilled labor and specialized suppliers, and increases opportunities for knowledge spillovers. The strategic value of these agglomeration economies may vary by firm, depending upon the relative value of each economy, and upon firm and agglomeration economy traits. To better determine when a firm will be attracted to agglomeration ec...

National identity is an important magnetic force that draws individuals and organizations to co-locate in the same geographic areas in foreign countries, thus providing a fertile socio-economic context for relationship formation and other social exchanges. Whether the focus is on individuals such as Chinese immigrants in Metropolitan cities (Zhou & Logan, 1989) or organizations such as Korean f...

www.phil.frb.org Business Review Q4 2003 7 www.phil.frb.org employment in the U.S. is located in metropolitan areas, and these areas account for 24 percent of the total land area of the country. Why is employment so heavily concentrated in selected areas of the country? Economists think that spatial concentration of employment (or, more generally, economic activity) develops for two very differ...

Nowadays, our society is characterized by high levels of social cohesion and cooperation that are in contrast with the selfish nature of human beings. One of the principal challenges for the social sciences is to explain the emergence of agglomeration and cooperative behavior in an environment characterized by egoistic individuals. In this paper we address this long standing problem with the to...

In this article, we explore the issue of industrial agglomeration and its relationship to economic development and growth in the less-developed countries of East Asia. We present theoretical arguments and secondary empirical evidence as to why we should have strong expectations about finding a positive relationship between agglomeration and economic performance. We also review evidence from the...

Recent economic analysis of outsourcing has focused on its international dimension. In contrast, this paper considers local outsourcing. The paper specifies and solves a model where the organization of production (vertically integrated or not) and the location of production (agglomerated or not) are jointly determined. The paper shows that agglomeration reduces opportunism, a thick market effec...

Anti-agglomeration is a promising solution for gas hydrate risks in deepsea hydrocarbon flowlines and oil leak captures. Currently ineffectiveness at high water to oil ratios limits such applications. We present experimental results of a new surfactant in rocking cell tests, which show high efficiency at a full range of water to oil ratios; there is no need for presence of the oil phase. We fin...
