this study investigates the relationship between market structure and profitability in the iranian manufacturing industries. in this study, raw data based on international standard industrial classification (at four digit code) has been used. fixed effects panel estimation method (based on diagnostic test results) has been chosen for empirical investigation. the result of the study confirms the...
The paper econometrically investigates the determinants of advertising intensity in the manufacturing industry of São Paulo, Brazil in 1996 taking as reference an extensive survey carried out by Fundação SEADE. The preliminary investigation indicated a substantial degree of endogeneity in structure and performance variables. The instrumental variables estimation also considered instruments refe...
Purpose There has been much research on manufacturing flexibility, but supply chain flexibility is still an under-investigated area. This paper focuses on supply flexibility, the aspects of flexibility related to the upstream supply chain. Our purpose is to investigate why and how firms increase supply flexibility. Methodology/Approach – An exploratory multiple case study was conducted. We anal...
There is a popular belief that Chinese imports have devastated US and European manufacturing and contributed to rising inequality. Somewhat paradoxically, the consensus amongst empirical economists is that trade has not been a major cause of rising wage inequality (although this is largely based on datasets predating China’s rise). We argue that both views have underestimated the positive impac...
Recent models of natural language processing employ statistical reasoning for dealing with the ambiguity of formal grammars. In this approach, statistics, concerning the various linguistic phenomena of interest, are gathered from actual linguistic data and used to estimate the probabilities of the various entities that are generated by a given grammar, e.g., derivations, parse-trees and sentenc...
The interaction of the eukaryotic translation initiation factor eIF4E with the initiation factor eIF4G recruits the 40S ribosomal particle to the 5' end of mRNAs, facilitates scanning to the AUG start codon, and is crucial for eukaryotic translation of nearly all genes. Efficient recruitment of the 40S particle is particularly important for translation of mRNAs encoding oncoproteins and growth-...
The standard quadratic price adjustment cost function makes no allowance for firm size or for scale economies. Incorporating quadratic price adjustment costs into the profit function, a firm’s speed of price adjustment is both shown to be a positive/negative function of its size when firms have scale economies/diseconomies with regard to these costs and to be a negative function of market power...
