  Ability-Biased Technological Transition, Wage Inequality, and Economic Growth

  摘要：

  本文提出了一种以能力偏向的技术转型为特征的增长模型，其中技术、教育程度和工资不平等的演变与过去几十年在美国和其他发达国家观察到的模式一致。它认为，技术进步速度的提高提高了能力的回报，同时导致技术工人和非技术工人群体之间和内部的工资不平等加剧，技术工人的平均工资增加，技术工人的平均工资暂时下降。非技术工人、教育程度的提高以及生产力的暂时放缓。

  A novel series of quinoxalin-2-carboxamides were designed based on the ligand-based approach, employing a three-point pharmacophore model; it consists of an aromatic residue and a linking carbonyl group and a basic nitrogen. The target new chemical entities were synthesized from the key intermediate, quinoxalin-2-carboxylic acid, by coupling it with various amines in the presence of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC center dot HCl) and 1-hydroxybenzotriazole (HOBt). The obtained compounds' structures were confirmed by spectral data. The target new chemical entities were evaluated for their 5-HT3 receptor antagonisms in longitudinal muscle myenteric plexus preparation from guinea pig ileum against 5-HT3 agonist, 2-methyl-5-HT, which was expressed in the form of pA(2) value. All the synthesized compounds showed antagonism towards 5-HT3 receptor; based on this result, a structure-activity relationship was derived, which reveals that the aromatic residue in 5-HT3 receptor antagonists may have hydrophobic interaction with 5-HT3 receptor. Regardless of their antagonistic potentials, all the synthesized molecules were screened for their anti-depressant potentials by using forced swim test in mice model; interestingly none of the tested compounds affect the locomotion of mice in the tested dose levels. Compounds with significant pA(2) values exhibited good anti-depressant-like activity as compared to the vehicle-treated group. (C) 2010 Elsevier Ltd. All rights reserved.

  This paper develops a growth model characterized by ability-biased technological transition in which the evolution of technology, education attainment, and wage inequality is consistent with the observed pattern in the United States and other advanced countries over the past several decades. It argues that an increase in the rate of technological progress raises the return to ability and simultaneously generates an increase in wage inequality between and within groups of skilled and unskilled workers, an increase in average wages of skilled workers, a temporary decline in average wages of unskilled workers, an increase in education, and a productivity transitory slowdown.
