The paper addresses the link between productivity and labour mobility. The hypothesis tested is that technology is transmitted across industries through the movement of skilled workers embodying human capital. The embodied knowledge is then diffused within the new environment creating spillovers and leading to productivity improvements. The empirical analysis is based on household survey and in...

Ownership structure and industry characteristics as internal and external factors respectively significantly impact the export performance of Chinese manufacturing firms. Three different yet related models, namely, logit, tobit and ordered probit models, that correspond to three different indicators of export performance are considered. It was found that the export performance of Chinese manufa...

there are different studies in urban literature on the determinants of urban growth, from the theoretical and empirical points of view. the most completed theoretical model is henderson model (1988, 1997, and 1999), which is tested by some empirical studies. as henderson model shows, the set of national product, specialization and technological progress are the determinants of urban growth. usi...

This paper presents the first use of close range terrestrial hyperspectral imaging to explore by-products from the iron and steel industry at a dump site cross section, using established mapping approaches in geological remote sensing. Laboratory reflectance measurements, X-Ray diffraction and chemical analysis provided a benchmark for the imaging results. In addition, terrestrial laser scannin...

The global steel price index is a leading indicator in the bulk shipping industry. A study of the global steel price index combined with the establishment of fuzzy time series models can be used to predict future trends in the trading range of the global steel price index. Analysis of applied fuzzy time series data shows the following results: (1) Price volatility of the global steel price inde...

this paper investigates the impact of oil revenues on the output of economic sectors in some of oil exporting countries including iran, venezuela and mexico. we use cointegration analysis as well as short run and long run granger casualties' tests. the results show that in the long run, an oil boom leads to expansion of service sector, in these countries. also, the impacts of oil revenues ...

Using historical, ®rm-level data, this study compares the productivity of Japanese and U.S. integrated steel producers. In recent decades Japanese producers have demonstrated higher labor productivity than their U.S. counterparts, due largely to higher investment. Calculations of multifactor productivity suggest that the American ®rms, nevertheless, maintain a small advantage in overall ef®cien...

background: groundwater resources in arid and semi arid regions are very important. groundwater is contaminated by agricultural, industrial and municipal activity which as a result reduces its quality. investigating of the chemical quality of the groundwater is emphasized to identify pollutant environmental impacts associated with incorrect waste disposal practice. this research investigated th...
