Multinational corporations (MNC) search increasingly for lead market knowledge and technological expertise around the globe. We investigate whether their subsidiaries gain access to these valuable sources of host country knowledge to the same degree as domestic rivals. We develop a theoretical framework for “why” and “how” a lack of embeddedness and legitimacy (liability of foreignness) may translate into additional obstacles for foreign subsidiaries. We test these hypotheses empirically using a broad dataset of more than 1100 firms in Germany. We find that MNCs can compete on an equal footing with host country competitors when it comes to generating impulses for innovations from universities. They are significantly challenged by liabilities of foreignness, though, when host country customers are involved. The disadvantages are especially pronounced when the host country industry is at the technological forefront. We suggest that the disadvantages arising from liability of foreignness in the host country are especially relevant when promising lead customers have to be identified and their tacit and often unarticulated impulses have to be transferred, understood and prioritized. Management recommendations are developed on the basis of these results. 相似文献

ABSTRACT This study is one of the first to explore the use of (drawn) visual vignettes in qualitative research in Africa. The vignette method was used to discuss the sensitive topic of people’s attitudes towards people with albinism in Tanzania among high school students. Focus was on two key questions: (i) To what extent was the vignette method implemented as intended?; (ii) Has the vignette method achieved its goal?. This research note discusses the effectivity of the visual vignette method as a tool to gain a better insight into people’s attitudes towards people with albinism, but also describes the possibilities of visual vignettes as a tool for research on other sensitive topics. 相似文献

ABSTRACT Apprenticeship programs are promoted to facilitate youth’s transition from school-to-work, especially for those who might not otherwise attend postsecondary education. These programs may help youth achieve other markers of adulthood earlier. In this paper, we draw on qualitative interviews with Canadian young men in the skilled trades to explore whether they believe their educational choices have given them an advantage in their transition to adulthood. We also draw from the 2011 GSS, a nationally representative survey, and Cox modeling to examine three early adult transitions – home-leaving, first union, and first marriage – to determine if apprenticeship programs facilitate earlier transitions compared to other educational streams. Our respondents expressed that they transitioned to adulthood more quickly than their peers, due to early employment and avoiding student debt, however, many also had trouble finding stable employment and often took on debt related to their training. Using nationally representative data, we find tradesmen tend to leave home earlier than their peers, they form first unions at younger ages but marry slightly later than their more highly educated counterparts. Our results contribute to our understanding of how apprenticeship programs in Canada facilitate transitions to adulthood among a recent cohort of young men. 相似文献

The present study investigated preschoolers' multiple sociomoral considerations (equality, equity, and perpetuating inequality) in a third‐party context of social inequality. Using a resource allocation task involving one wealthy and one poor character, we examined how 3–5‐year‐old children (N = 100) allocated either necessary (must‐have) or luxury (nice‐to‐have) resources. In addition, preschoolers' emotions, reasoning, and judgments were assessed. Results indicated that preschoolers distributing more resources to wealthy than poor others displayed a decision‐making pattern distinct from preschoolers allocating equally or equitably and largely matched the numeric proportions of the inequality in their allocations. In addition, preschoolers were sensitive to the differential implications of necessary and luxury resources, thereby considering others' needs in their moral decisions. Emotions were related to reasoning, but did not mediate the relationship between judgment and behavior. These findings demonstrate novel aspects of preschoolers' multifaceted moral considerations in the context of resource inequality. 相似文献

A transition to electric vehicles (EVs) is widely assumed to be an important step along the road to environmental sustainability. However, large‐scale adoption of EVs may put electricity grids under critical strain, since peaks in electricity demand are likely to increase radically. Efforts to manage demand peaks through pricing schemes may create new peaks at low‐price periods, if large numbers of EV owners use smart charging to benefit from low prices. This effect is expected to be amplified when EV owners adopt smart decision support to assist them with optimal charging decisions. Therefore, energy policymakers are interested in advanced pricing schemes that can smooth demand or induce demand that comes as close as possible to a desired profile. We show, through simulations calibrated with real‐world data, that current approaches to electricity pricing are limited in their ability to induce desired demand profiles. To address this challenge, we present adaptive pricing, a method to learn from EV owner reactions to prices and adjust announced prices accordingly. Our method draws on the Green Information Systems principles and can assist grid operators in ensuring the reliable operation of the grid. We evaluate our results in simulations, where we find that adaptive pricing outperforms current electricity pricing schemes, yielding results close to the theoretically optimal ones. We test our method in inducing both flat and extremely volatile demand profiles, and we see that in both cases it manages to induce EV charging close to the ideal scenario under perfect information. 相似文献

The debate about the structural change of the labor market and the organization of dependent work has not been decided, neither theoretically nor empirically. This paper investigates on the basis of data from the GSOEP (German Socio Economic Panel) the entry into the labor market and the first years of gainful employment for four birth cohorts. The central focus of our argumentation lies on the following questions: Is there an increase of atypical entries into the labor market (aged 15 to 26) — i.e. part-time employment, unemployment or non labor market participation — and what proportion of their first years of working life (aged 15 to 36) do people spend in full-time employment. The results show a rise of atypical entries into the labor market for the younger cohorts. The duration of male full-time employment will be shorter because of longer education periods, while this duration rises for women as a result of decreasing relevance of housewife work. An atypical entry into the labor market has long-term consequences for the further working life, so that it hardly can be compensated. A de-standardization of the entry into the working life is most frequent for men and women with lower professional qualification. The results show that society is increasingly polarizing along the lines of qualified and non-qualified persons. 相似文献

Assisted reproduction has a minor but increasing influence on childbearing trends in advanced societies. In Denmark, the use of assisted reproduction technology (ART) has become particularly widespread. At the same time, Danish women born in the late 1950s and the 1960s experienced stabilization or even a slight increase in their mean number of children. Broad availability and widespread use of assisted reproduction may become important factors contributing to maintaining relatively high completed fertility among the younger cohorts of Danish women. To explore this idea, we analyze and project cohort trends in fertility rates among native Danish women born in 1960‐78 and examine the likely contribution of assisted reproduction to these trends. The projected proportion of children born after ART treatment shows a substantial increase from 2.1 percent among women born in 1965 to 4‐5 percent among women born in 1978, with an estimated net impact of ART (as compared with the hypothetical situation where no ART treatment was available) on the order of 3‐4 percent. When intrauterine inseminations are included, this implies that up to 7 percent of children of those native Danish women born in 1975 and later will likely be conceived by infertility treatment. 相似文献
