In this paper, we show that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest‐ and lowest‐paid jobs compared to middle‐wage jobs. The most popular explanation for such a pattern is the hypothesis of task‐biased technological change, where technological progress reduces the demand for routine middle‐wage jobs but increases the demand for non‐routine jobs located at the tails of the job–wage distribution. However, our estimates do not support this explanation for the 1970s and 1980s. Stronger evidence for task‐biased technological change, albeit not conclusive, is found for the 1990s and 2000s. In particular, there is both a statistically and economically significant growth of non‐routine jobs and a decline of routine jobs. However, results for wages are mixed; while task‐biased technological change cannot explain changes in between‐occupation wage differentials, it does have considerable explanatory power for changes in within‐occupation wage differentials.  相似文献

Firms undertaking independent and cooperative research and development (R&D) activities simultaneously often have difficulties to realise their synergistic effects. This study contends that such difficulties are caused by tensions between two types of R&D activities in terms of resource competition and knowledge leakage. Moreover, organisational slack and absorptive capacity may affect these tensions and thereby play important role in synergizing independent and cooperative R&D activities. Based on a survey data of 286 firms, this study finds that such two types of R&D activities jointly have a negative impact on firm performance. Furthermore, organisational slack aids in synergizing them, while absorptive capacity has an adverse impact. These findings enrich our knowledge on the interrelation of independent and cooperative R&D activities and shed light on how firms can synergize them.  相似文献

Current results of direct relationships between collaboration and innovation capability on performance in tourism contexts are inconsistent. This research is to uncover roles of collaborative routines on promoting relationships between internal and service innovation capabilities as two distinct mechanisms, and performance. The study also examines the contingent effect of knowledge search on performance. Survey data from 181 samples from the Thai tourism industry are gathered for analyses. Findings demonstrate that knowledge search and internal innovation capability have a direct impact on performance, whereas the effect of service innovation capability on performance is significant only in the presence of collaborative routines.  相似文献

This article examines the effects of excess capacity on the production cost and technical inefficiency of hotels and restaurants in Norway. The dataset includes a daily unbalanced panel of 94 hotels and restaurants from 2003 to 2014. To accommodate inefficiency, we use an input distance function (IDF). Inefficiency in the IDF means that if inputs are overused by k% then production cost is also increased by k%. We also allow inefficiency to differ across locations and regions by using them as determinants. The results indicate that excess capacity considerably affects the cost and increases inefficiency. The marginal effect on cost increases with excess capacity, but the effect on inefficiency sets in when it exceeds 50 percent. Furthermore, we find less overuse of inputs by firms in small metro towns and the Northern region causing them to be more efficient [except for the Southern and Western regions] than their counterparts.  相似文献

This paper discusses the situation of China's air cargo sector facing the COVID-19 pandemic. Based on the expectation that it can go out of recession more easily than China's air passenger sector, this paper analyzes four aspects that are favorable and unfavorable for its further development: (1) strengths (China's sustainable economic basis and proliferating cargo suppliers), (2) weaknesses (insufficient cargo capacity and less business internationalization), (3) opportunities (top authority support, rising e-commerce demand, and new technological momentum), and (4) challenges (uncertain trade environment and increasing profitability pressure). Then this paper suggests strategies for China's air cargo suppliers to adapt to the pandemic.  相似文献

This study aims to examine how technology interdependence and three environmental variables, namely political instability, technological uncertainty and Confucian dynamism, in the host country collectively influence Taiwanese technological multinational company’s (MNC) entry mode choice between joint venture (JV) and wholly owned subsidiary (WOS). Grounded on theories of transaction cost economies and organisational design, this study hypothesises a positive technology interdependence–WOS relationship that can be explained by appropriation and coordination concerns. Moreover, the aforementioned relationship can be positively moderated by technological uncertainty while negatively moderated by political instability and Confucian dynamism. These hypotheses were examined and supported using logistic regressions in the analysis of 195 foreign entries undertaken by Taiwanese information and electronic MNCs.  相似文献

The article presents an alternative view on the education—income inequality relationship, which calls into question the neoclassical claim that education increases labor productivity and hence contributes to a higher output, wage and consequently more even income distribution. In the context of public policies, education needs to be seen not only as a factor of income mobility, but also as a “positional good,” which benefits graduates at the expense of non-graduates. Education generates “academic rent,” by which we mean uneven remuneration of workers based on academic signs of distinctions that do not necessarily reflect differences in productivity. Using the robust panel model on a sample of OECD (Organization of Economic Co-operation and Development) countries from 1980 to 2015, we show that investments in human capital lead to lower inequality, but overinvestments tends to increase income inequality, which may be related to academic rent. In discussing this result, we consider that uncertainty of academic rent under the condition of a rapid transformation of the workplace caused by the fourth industrial revolution.  相似文献

本文采用中国1987~2013年的宏观经济数据,对经济改革与技术创新能力之间的关系进行了深入的研究。研究结果表明,经济改革与技术创新能力之间存在单向因果关系,经济改革是技术创新能力变化的原因;长期均衡状态下,技术创新能力提升的近30%可由经济改革解释;短期中,经济改革的短期波动对技术创新能力短期波动的影响在所有的短期波动中占主导地位。  相似文献
