Real options (RO) valuation has been promoted as a way to evaluate investment opportunities and make investment decisions that takes into account the value of managerial flexibility in the face of uncertainty. Although RO enjoys a substantial body of literature considering its application and suitability in different situations, the impact of national culture on the application of RO has received little attention. Values embedded in national culture affect the behavior of managers. In particular, these values play a role in how managers frame information, communicate, and make decisions, directly and indirectly affecting behavior through cultural layers such as organizational culture. National culture, therefore, can systematically affect the application of RO, potentially leading to suboptimal outcomes. In this article, we hypothesize how 2 particularly relevant dimensions of culture, power distance and uncertainty avoidance, affect RO exercise, and estimate the magnitude suboptimality of these effects using a model we develop for the case of a put option. Our estimates suggest RO may not always be a superior valuation approach to net present value for national cultures with certain characteristics. 相似文献

The cross‐cultural study of LMX and individual employee voice: The moderating role of conflict avoidance 下载免费PDF全文
This article examines the role of national culture, measured by conflict avoidance, on the relationship between leader–member exchange (LMX) and individual employee voice. Using data collected from automotive industry employees in the United States and Korea, the findings show that conflict avoidance is negatively related to employee voice and also moderates the relationship between LMX and employee voice in the Korean sample. In particular, the relationship between LMX and voice becomes less positive when conflict avoidance is high. On the other hand, conflict avoidance does not have a direct effect on employee voice as well as an interactive effect with LMX on employee voice in the U.S. sample. This study, therefore, highlights the importance of the national culture in the comparative study of employee voice. 相似文献

稻鳅共生种养模式试验研究 总被引:2,自引:0,他引:2
[目的]稻鳅共生是典型的稻田综合利用模式,符合生态农业发展方向。通过对稻鳅共生生态系统的生理生态学机制开展试验研究,为进一步推广稻鳅共生种养模式提供科学依据。[方法]采用田间试验方法,以水稻单作为对照,研究了不同泥鳅养殖密度下的稻鳅共生对水稻农艺性状、土壤理化性质、水稻产量构成的影响,并对稻鳅共生种养模式进行了经济效益分析。[结果]与对照处理相比,水稻长势在株高、有效分蘖率、根长等方面有一定提高。养殖田水稻株高增高了3%,有效分蘖率提高了8%~11%,根长提高了8.8%~31.3%。在土壤理化性质方面,与对照相比,土壤容重降低了7.1%~21.2%,孔隙度增加了4.1%~14.7%。实验前后养殖田内土壤有机质增加了3.5%~26.5%,对照田降低了2.5%~5.8%。土壤肥力(氮、磷、钾)减少,但减少幅度小于对照处理。稻鳅共生种养模式下水稻产量提高了5%~25%,同时稻田增收泥鳅1 725~3 375kg/hm2,净收入为1.836 0万~2.307 0万元/hm2,经济效益提高了3.65~4.84倍。稻鳅共生种养模式中泥鳅的养殖密度为30万尾/hm2时稻田的生态效益和经济效益最佳。[结论]稻鳅共生有效改善了土壤理化性质,促进了水稻的生长,提高了稻田产量和产值。 相似文献

Recent statistics suggest that there is a continuing disparity in labour market outcomes between ethnic minority (EM) groups and their White counterparts. However, although there is now an abundance of statistical and anecdotal evidence that speaks to the disadvantage of EM groups, there is less understanding of the intraorganisational dynamics that give rise to the outcomes that are reported. Drawing on postcolonial, cultural capital, and social capital theories, this article argues that the dominant approach through which organisational culture is conceptualised and the ways in which it is commonly managed may encourage labour market inequality and disadvantage for EM groups (defined as access to employment and having opportunities for promotion while in employment). The article explores three intraorganisational interventions that are common in culture management initiatives (leadership, selective recruitment, and internal promotion) to illustrate the arguments. The article concludes by discussing a series of implications and highlighting the pivotal role of the HR academy and practitioners in generating deeper insights and attention into the potential sources of EM disadvantage that are linked to culture and culture management. 相似文献

零售业自营与联营之争由来已久,在当前供给侧结构性改革、完善促进消费体制机制以及零售业寻求创新发展的背景下,有必要对这一问题展开进一步的理论探讨。文章结合马克思流通经济理论指出,自营和联营的本质区别在于是商业资本还是产业资本承担商品流通职能,自营和联营并不是非此即彼的互斥关系,但如果零售业完全倚重其中一种模式并在全社会推向极端,则需要反思商业资本和产业资本是否各得其所和高效分工。在中国流通体制变革中,虽然联营模式在特定历史时期帮助众多零售企业渡过生存危机并推进内资零售快速扩张,但发展至今,已呈现零售业普遍联营的情况,使零售业整体面临着制约创新发展的新问题。数字经济为零售业回归自营提供了有利契机,零售企业应充分利用新技术摆脱联营制的路径依赖,依托数字化开展深度自营并全面提升流通效率。 相似文献

We examined how factors from Indigenous entrepreneurship research (social capital, cultural capital, self-efficacy) help explain the high level of Māori entrepreneurial performance in the mainstream screen industry. Results, based on ten case studies and a one-year series of structured interviews, extend prior research by showing that these Indigenous entrepreneurs benefit jointly from two forms of capital: cultural and social. We found high levels of both forms to increase the desire for emancipation of cultural and community identity – not just individual identity – through entrepreneurship. Self-efficacy and storytelling helped ameliorate discontinuities across Indigenous and mainstream contexts. Our research sheds new light on how Indigenous ventures can pursue mainstream entrepreneurship while maintaining cultural identity. It also makes several distinct contributions to the Indigenous entrepreneurship literature. First, it provides an integrative theoretic review. Second, it illustrates a culturally appropriate methodology for researching Māori entrepreneurs with implications for other Indigenous communities. Third, it proposes cultural capital and social capital as a two-part framework for explaining Indigenous entrepreneurial action. Fourth, it shows how entrepreneurship can be empowering for Indigenous communities. Finally, our paper demonstrates that entrepreneurship is a promising mechanism for preserving and promoting the cultures of Māori and other Indigenous peoples. 相似文献

体育教学“以人为本”观念形成的社会环境是现代化发展的必然结果。我们教育改革思路提出“健康第一”的指导思想,同样验证了“以人为本”的现代体育观念的社会环境背景。学生对体育课的要求和看法将对体育教学改革提供“主体”依据,体育教学改革要“以人为本”。 相似文献
