We provide an institutional insight into the trend of income polarization within the U.S. working class. In contrast to the previous industrial waves, the current and ongoing industrial revolution is characterized by the replacement of “creative destruction” with jobless growth. Instead of replacing the lost jobs with new ones, new disruptive technologies eliminate more jobs in traditional labor and capital-intensive sectors than create jobs in new idea-intensive sectors. By examining the relationship between the income share of the bottom 50 percent, the middle 40 percent, and the top 10 percent and technological progress, we obtain robust econometric results. According to our results, the income polarization among U.S. workers can be associated with the shift of R&D activities from the public to the corporate sector. The concentration of innovations by corporate capital limits the power of society to reduce inequality and to provide greater social stability through “the incredible productivity” of technological progress. 相似文献

This paper investigates the relationships between stock returns, changes in production, and changes in interest rates in three European countries: France, Germany, and the United Kingdom. The results obtained using annual data are much more conclusive than those obtained using quarterly data. Stock returns are affected by current changes in interest rates and by future changes in production. The dependence on changes in interest rates seems to be higher than on changes in production. Furthermore, the influence of future changes in production on stock returns diminishes substantially when contemporaneous changes in interest rates are taken into account. With reference to these points, the European markets behave in a similar fashion, but are in sharp contrast with the U.S. market.I am very grateful to Kay Davidson, Patric Hendershott and two anonymous referees for useful comments and suggestions. I am solely responsible for all remaining errors. 相似文献

20世纪30年代前期,专科以上学校毕业生失业严重。在学生运动风起云涌之际,设立专科以上学校毕业生就业训导班,被国民政府赋予解决专科以上学校毕业生就业问题的重大使命。就业训导班声势大、力量强、目标明确,部分反映了国民政府试图纠正专科以上学校毕业生就业问题的努力。然而该班的设立因被动、临时、人数有限,且并不触及就业问题的根本,而成为国民政府安抚学生和社会情绪的又一项权宜之计。 相似文献

ABSTRACTHow do employees in “new services”, such as coffee baristas and gym trainers in India, see their jobs? In this paper, we build on extensive fieldwork in gyms and coffee chains that cater to the emerging Indian middle classes. Our research highlights the importance of respect and recognition in making service interactions more meaningful for new service workers. Generally hailing from the lower middle classes, new service work offers important opportunities to interact with and learn from English-speaking upper middle-class customers and clients. Besides the opportunity to interact and learn, the acknowledgement they receive for their skills and (bodily) accomplishments make such professions attractive as well. Even if this holds the potential for upward socioeconomic mobility, our findings also point at the resilience of social hierarchies. Drawing on literature on service interactions and new middle-class formation in India, this paper provides important insight into how young Indians navigate and negotiate the opportunities and pitfalls that come with the country's changing socioeconomic landscape. 相似文献

Abstract The quality of vehicular collision data is crucial for studying the relationship between injury severity and collision factors. Misclassified injury severity data in the crash dataset, however, may cause inaccurate parameter estimates and consequently lead to biased conclusions and poorly designed countermeasures. This is particularly true for imbalanced data where the number of samples in one class far outnumber the other. To improve the classification performance of the injury severity, the paper presents a robust noise filtering technique to deal with the mislabels in the imbalanced crash dataset using the advanced machine learning algorithms. We examine the state-of-the-art filtering algorithms, including Iterative Noise Filtering based on the Fusion of Classifiers (INFFC), Iterative Partitioning Filter (IPF), and Saturation Filter (SatF). In the case study of Cairo (Egypt), the empirical results show that: (1) the mislabels in crash data significantly influence the injury severity predictions, and (2) the proposed M-IPF filter outperforms its counterparts in terms of the effectiveness and efficiency in eliminating the mislabels in crash data. The test results demonstrate the efficacy of the M-IPF in handling the data noise and mitigating the impacts thereof. 相似文献

Agricultural applications of nanotechnology are at a relatively early stage and little is known about consumer responses to the technology. Canadian consumer responses to food nanotechnology are examined through the lens of the Food Value Scale. Data from a survey of Canadian consumers are used to evaluate the relative importance of eleven food values to food purchase decisions. We find that taste, safety, nutrition, and price are among the most important food values to Canadians, however, consumers exhibit considerable heterogeneity with respect to the priority placed on these values. A discrete choice experiment (DCE) explores the effect of food values on choice behavior. The DCE is positioned as a sliced apple product with non-browning and antioxidant-enhanced features introduced through the use of nanocoating or a conventional coating method. Random parameters logit (RPL) and latent class models (LCM) confirm the existence of significant preference heterogeneity. The LCM identifies three classes of consumers: “supporters,” “doubters,” and “opponents” who differ in their reaction to nanotechnology and in the relative importance placed on food values such as naturalness, novelty, and convenience. The analysis shows that food values provide additional insights into consumers’ food choices and their attitudes toward novel food technologies. 相似文献

This article interrogates the nature of political agency deployed at sites of market‐oriented water reforms. It presents a case study from Bangalore, India of a water project mandating significant ‘beneficiary’ cash contributions from lower‐middle‐class dwellers for the capital cost of extending piped water to the city's peripheries. Drawing on quantitative and ethnographic data, it illustrates why property owners who lack formal water access and land tenure — groups referred to in this article as the ‘peripheralized middle class’ — consent to paying for pipes rather than resist all together despite the high cost involved. It argues that far from reflecting an internalization of a ‘willingness to pay’ or ‘stakeholder’ ethos celebrated by development practitioners today, payment for water provides an insurgent means to bargain for greater symbolic recognition, respectability and material benefits from the state. In particular, payment for pipes enables peripheral dwellers to strengthen their claims to secure land tenure in an era of exclusionary and punitive spatial policies. Payment thus comprises a terrain of contested meaning making and political struggle, at the heart of which lie the stakes of urban citizenship. In documenting the process by which property related interests and tenure claims are advanced under a scenario of reforms, this article contributes to Gramscian political‐ecological conversations on subaltern political agency and the lived character of hegemony in urban environments. 相似文献
