Trajectories of gender identity were examined from Grade 6 (Mage = 11.9 years) to Grade 9 in European French (n = 570) and North African French (n = 534) adolescents, and gender and ethnic group differences were assessed in these trajectories. In Grade 6, boys of both ethnic groups reported higher levels of gender typicality and felt pressure for gender conformity than girls. European French girls and boys and North African French girls reported decreasing gender typicality from Grade 6 to Grade 9, whereas North African French boys did not change. Felt pressure decreased among girls, did not change in European French boys, and increased in North African French boys. Ethnic and gender differences in gender identity development are discussed. 相似文献

We analyze the influence of a regional economic integration agreement (REIA) on a firm's investments in research and development (R&D). A country's entry into a REIA creates two competing influences on the firm's R&D investments. On the one hand, increased competition in product markets after the REIA would induce the firm to invest in internal R&D to improve its distinctive technological competitiveness. On the other hand, better access to sources of inputs in factor markets after the REIA would induce the firm to purchase external R&D because it can outsource technology more easily. Surprisingly, the empirical analysis shows that the REIA's impact on R&D investment is driven primarily by product markets rather than by factor markets. After the REIA, product markets induce firms not only to invest more in internal R&D but also purchase more external R&D. In contrast, after the REIA factor markets have limited influence on internal or external R&D investments. 相似文献

Despite the growing involvement of multinational enterprises (MNEs) in foreign-based research and development (R&D), there has been little research comparing R&D investments of subsidiaries of foreign MNEs to domestic firms. Subsidiaries of foreign MNEs enjoy advantages that help them compete against domestic firms. However, when deciding on R&D investments, these advantages exert competing influences on their R&D investment decision. On the one hand, better access to and transfer of knowledge and technologies from the MNE and other subsidiaries and centers of excellence may encourage the subsidiary of a foreign MNE to invest less in R&D relative to a domestic firm. On the other hand, better access to sources of capital through the MNE and other subsidiaries may induce the subsidiary to invest more in R&D in comparison to domestic firms. We find that subsidiaries of foreign MNEs invest less in total R&D than domestic firms. The reason is that they invest less in external R&D than domestic firms; however, they have similar internal R&D investments compared to domestic firms. These findings support the notion that the transfer of technology and knowledge from other parts of the MNE acts as a substitute for the purchase of external R&D while internal R&D acts as a complement to the technology and knowledge transferred from other parts of the MNE. 相似文献
