Using information on a panel of multinational firms operating in the United Kingdom from 1996 to 2005, we find that labour demand in domestic multinationals is less sensitive to labour cost changes than in foreign multinationals. This difference in the wage elasticity of labour demand persists even when we control for the skill intensity of firms or their level of intangible assets. This is in line with an interpretation that the provision of headquarter services in domestic multinational firms protects against strong fluctuations in labour demand. Overall, our results suggest that the wage elasticity of labour demand is about 40 % lower in domestic than in foreign multinationals.  相似文献

Migrant’s media use is a growing research field in communication. This article offers an integrated view on the relationship of media use, adolescents’ identity development and social integration. Based on Hurrelmann’s conceptualization of (media) socialization, Esser’s integration theory and Keupp’s concept of identity development, this study deduces a theoretical framework for analyzing the importance of individual and mass media in the process of adolescent immigrant’s social integration. Empirically, an exploratory-qualitative survey consisting of eight group discussions and ten face-to-face interviews highlights the importance of the hybrid character of socialisatio in multi-cultural entities (community of origin and admission). The media’s role in this process is limited.  相似文献

Background Regularly available data has been shown to be inadequate for developing, implementing, and evaluating injury prevention and control programs in Nicaragua. A specific prevention-oriented local injury surveillance system has therefore been set up in the city of León. Objectives The aim of this paper is to describe the epidemiology of fatal and non-fatal injuries over a one-year period in a well-defined local population in Nicaragua, as emerging from the perspective of emergency room and inpatient treatments over a one-year period. Methods A hospital-based injury surveillance system was established to collect data for different levels of severity. All treated unintentional and intentional injuries were registered, including information on the external causes according to the ICD-9. Results Of all emergency room visits, 15.9% (9,970) were injuries. For every death due to injuries, there were 31 hospital admissions and 253 emergency room visits. Home and street/roads were the main arenas for the accidents. The estimated underreporting rate was about 6%, and in 20.3% of the cases, no E-code was assigned. The overall incidence and mortality rates were 56.2 per 1,000 and 20 per 100,000 inhabitants, respectively. However, comparison with a parallel household survey showed that the reporting rate of the surveillance system is only about 9%. The overall ratio of male to female injury rates was 2.1 to 1. The main causes of non-fatal injuries were falls, whereas the main cause of death was traffic accidents. Conclusions Hospital discharge and emergency room data systems are effective and feasible means for collecting the data needed to prevent injuries. However, in a country like Nicaragua with limited access to hospital health services, it is necessary to supplement such a system with additional sources of information in order to gain a more comprehensive picture of injury occurrence.  相似文献

By making use of a large‐scale randomized experiment, we test whether social behaviour is important for work absence due to illness. The individuals treated in the experiment were exposed to less monitoring of their eligibility to collect sickness insurance benefits, which sharply increased their non‐monitored work absence. This exogenous variation is exploited in two complementary analyses. In both analyses, we find significant social‐behaviour effects. Using detailed data, we conclude that the social‐behaviour effects most likely stem from fairness concerns.  相似文献
