Abstract This paper presents new evidence on industry concentration at both the country and world-region levels. It calculates country-level measures from novel data representative of entire firm population in 12 European countries, it develops a methodology for calculating supranational level using detailed cross-country subsidiaries business groups. documents that has increased not only North...

Starting from the 1980’s, the U.S. paper and paperboard industry has recorded an increasing degree of consolidation through mergers and acquisitions. This strategy, combined with voluntary downtime, is adopted by producers as a mean to tackle excess capacity and to reduce costs in order to improve profitability. However, it is unclear whether the rising market concentration resulted in market p...

We propose that the effect of market concentration on firm survival is different according to whether an industry is static (low entry and exit) or dynamic. In our empirical analysis we find support for this hypothesis. Industry concentration rates reduce the survival of new plants but only in markets marked by low entry and exit rates. Specifically, a 10 percent increase in the 5-firm concentr...

the isolated fungi species of different kinds from chromium contaminated soil sites located in nagalkeni, chennai were used for reducing chromium(vi) in a tannery industry wastewater of nagalkeni, chennai.  the experiments were conducted to know biosorption potential of isolated fungi species for removing chromium(vi) in a tannery industry wastewater against the different ph, fungi biomass and ...

Erosion caused by sand transportation in flow changing devices is a serious concern in the hydrocarbon and mineral processing industry, which entail to failure and malfunction of flow devices. In this study, computational fluid dynamics (CFD) with discrete phase models (DPM) were employed for analysis of carbon steel long radius 90-Degree elbow erosion due to the sand concentration of 2, 5 and ...

sawdust which is the main waste from wood industry has been used as a raw material forremoval of brilliant cresyl blue toxic dye. the effects of various parameters such as ph,electrolyte concentration, adsorbent dose, contact time and agitation rate were studied for theremoval of the dye in a concentration of 50 mg l-1. the optimum condition for the studiedparameters was applied for various con...
