Technology and Firm Size-Wage Differentials in Colombia, Mexico, and Taiwan (China)
利用哥伦比亚、墨西哥和中国台湾的企业数据，研究发现企业的技术投资（研发和培训）会显著提高技能工人的工资，但对非技能工人影响不大，这解释了企业规模工资差异。
In many economies, studies have found large wage differentials not accounted for by work force characteristics, collective bargaining, or market power. Researchers attribute these differentials to either unobserved worker quality or pay incentives designed to elicit worker effort. This article finds empirical support for an alternative explanation: These wage differentials result from firms' technology-generating activities. Using firm-level data from Colombia, Mexico, and Taiwan (China), the article compares the effects of research and development, worker training, and exports by employers on the wages of skilled and unskilled workers. The results suggest that technology investments lead to large wage premiums for skilled workers but not for unskilled workers. These wage premiums are primarily the result of investments in research and development and in training, while exporting is relatively less important except in Colombia.
