The vast bodies of studies in the word and recently in Iran have attempted to investigate the manufacturing industry structure (indicating the level of industries in terms of monopoly or competitiveness) and its trend using the various indices and methods. Despite the importance of Lorenz Curve and Gini Coefficient in indicating the market structure, these methods, capabilities have been neglec...

We analyzed blood lead (PbB) level from the 2003 health surveillance results of 13,043 lead workers from 1,217 total lead industries to evaluate lead intoxication at low level in Korea. Geometric mean of PbB was 6.08 microg/dl and 56.6% and 7.9% of total lead workers had PbB level over than 5 microg/dl and 25 microg/dl, respectively. Male showed relatively higher PbB level compared to women, bu...

Product cycle theory has developed countries inventing goods and developing countries copying them. Once copying takes place, developed countries abandon the market – either outright, or through vertical differentiation – because of developing country cost advantages. Matching US imports and exports at the product level, I find evidence of both reactions – moving up and moving out – across manu...

This paper employs artificial neural network and decision tree to derive knowledge about the job attitudes of Generation Xers. The sample frame consisted of 1000 large Manufacturing Industries and 500 large Service Industries, randomly selected from the Common Wealth Magazine 1000 index of Taiwan Manufacturing Industries and Service Firms. Then, we exploited the ART2 neural model to take the co...

Recent years have seen an increased interest in using yield management techniques to maximize profitability in capacity constrained situations. The general principles and history of yield management are reviewed. General implementation issues and techniques are discussed, and various industries are considered for impact and specific implementation issues. Service and manufacturing industries ar...

he empirical studies have shown that cost advantages can occur due to economies of scale and economies of learning. However, a few studies have attempted to distinguish between these two effects on reducing costs. This paper is the first attempt on recognizing the impact of learning on reducing the cost with distinguishing the effect of economies of scale in Iran. Therefore, this study aims to ...

We examine the relationship between import competition from low wage countries and the reallocation of US manufacturing from 1977 to 1997. Both employment and output growth are slower for plants that face higher levels of low wage import competition in their industry. As a result, US manufacturing is reallocated over time towards industries that are more capital and skill intensive. Differentia...
