Capital–Skill Complementarity: Does Capital Composition Matter?

We estimate the effect of capital composition on the size of capital–skill complementarity and the skill wage premium. Disaggregating the capital stock into different types according to technological content, we find that: capital is more of a q‐complement to skilled labor than to unskilled labor; the higher the technological component of capital, the larger the size of the relative q‐complementarity between capital and skilled labor; and replacing non‐technological with technological capital might increase the skill wage premium by about 9 percent. Our results highlight that changes in capital composition matter for understanding changes in the skill wage premium.     

Can older workers stay productive? The role of ICT skills and training

This paper quantitatively examines the effects of aging on labor productivity using individual worker data in Korea. We find that information and communications technology (ICT) skills and participation in job-related training can help older workers stay productive. The estimation results present that ICT skills, a measure incorporating an individual’s proficiency in ICT skills and their utilization in the workplace, has a positive effect on the wages of the older workers aged 50–64 with a high level of education or in a skill-intensive occupation. Job training also has a significant positive effect on the wages of older workers. These results imply that compared to younger workers, well-educated older workers can obtain greater productivity increase through ICT skill attainment and their adequate use, and job-training. The evidence suggests that a productivity decrease in line with the aging process can be mitigated by training aging workers to equip themselves with ICT skills.     

施工企业工程项目部的建设浅论

工程项目的一次性决定了工程项目部的一次性，而工程项目成本中心与企业利润中心地位又辱致工程项目部的临时性，在工程项目实践过程中，项目经理部的一次性在实现其功能的过程中可能会产生很多局限和负面影响，故项目部应具有相对的稳定性，在此基础上，本对工程项目部建设实践进行了初步总结并提出了建议。     

Skill Classification and the Effects of Trade on Wage Inequality

The extent to which rising wage inequality in developed nations can be attributed to increased North-South trade has been a contentious issue over the last 20 years. We contribute to the debate by outlining a new skill classification method and evaluating the link between trade and wages using an economy-wide model. Our skill classification considers both academic and vocational qualifications and uses cluster methods to group together occupations with similar skill characteristics. JEL no. F16, J24, J31     

Sales trainer roles, competencies, skills, and behaviors: A case study

Numerous studies have examined different issues related to evaluating the effectiveness of sales training programs. Limited needs assessment, lack of training objectives, no alignment between training objectives and corporate goals, and sales training content, are all potential factors that can influence the effectiveness of training programs. Yet, little attention has been paid to the role of a central actor in the training process — the sales trainer. The evaluation of sales training programs is incomplete without taking into consideration the qualifications of the trainer. Through a case study, this paper suggests there are 8 roles that are associated with the sales trainer position. To effectively execute these roles, this exploratory investigation identified 18 related skills that are grouped into 5 competencies. Recommendations are offered regarding the relevance of this research for practitioners and suggestions are provided for future research in this area.     

Developing a framework for understanding the impact of deskilling and standardisation on the turnover and attrition of chefs

The occupation of cookery has been identified as one sharing a shortage of skilled employees. While the trade attracts moderate numbers of new recruits, the attrition or wastage rate, either before completion of an apprenticeship or soon after, is high. While chefs share many of the traditionally perceived poor working conditions of their hospitality colleagues, well documented in the literature, this paper presents an alternative explanation for their high mobility. It will be argued that labour mobility and attrition rates partly result from deskilling and standardisation. These are often consequences of technological applications in the kitchen, business operators seeking outsourced means of production and the controlled production of menus and recipes. This paper will examine the processes of deskilling and standardisation in the contemporary professional kitchen and their relationship with labour mobility, primarily through intention of labour turnover models. Particular attention will be given to occupational communities in this relationship, since it is widely accepted that creativity and skill are defining features of chefs’ occupational culture. Finally, a model will be proposed that reconciles the unique occupational experiences of chefs with generic, and hospitality specific, intention of labour turnover models.

Skill premium in Portuguese manufacturing industries

The debate between the skill-biased technological change (SBTC) approach and the international trade (IT) explanation to obtain the best explanation for the wage gap between skilled and unskilled workers continues. In this article, we divide the Portuguese manufacturing industries into high-tech and low-tech and study the approach that best justifies the wage gap, for the period between 2007 and 2014. The results point out that the SBTC approach is the main explanation to the formation the wage gap between the labour force with tertiary education (skilled) and with secondary and primary education (unskilled).     

中国制造业就业增长的反向变动趋势

本文试图考察在我国技术进步偏向资本增加情况下,资本深化对劳动密集型、资本密集型和技术密集型制造业就业增长的反向作用。鉴于我国技术进步具有要素偏向性,本文在构建理论模型时加入有偏技术进步假设,发现在技术进步偏向资本要素投入的条件下,资本深化会加深对就业的负向冲击。并利用wind数据库公布的中国制造业2383家上市企业2007-2018年数据,从横向和纵向两个维度验证了这点,结果发现:(1)在技术进步偏向资本要素投入时,资本劳动比增长率提高会降低整个制造业的就业增长率,技术进步吞噬就业。但是,资本深化对劳动密集型与资本密集型、技术密集型的就业增长作用呈反向趋势。(2)自供给侧结构性改革提出后,该反向变动趋势加强。这意味着,在技术进步和制造业深度融合过程中,劳动者需不断提高自身技能,提高就业竞争力;企业和政府配合提供培训支持,防止工人由于技能不匹配而导致大规模的结构性失业。
