Studies on the determinants of entrepreneurship emphasize that challenged adults tend to become entrepreneurs. However, research has not addressed the childhood origins surrounding the propensity for entrepreneurship. This article links childhood adversity to the propensity of individuals to become migrant entrepreneurs later in life. We test hypotheses derived from this theory in the context of whether, and when, children who survived the Great Chinese Famine of 1959–1961 became migrant entrepreneurs. Results strongly indicate that those who survived greater hardship during the Famine are more likely to become entrepreneurs, especially when they were younger during the famine years. We also find that being younger at the time of migration increased the likelihood of becoming entrepreneurs in their new locale. Overall, this study casts light on why, how and when childhood adversity shapes the propensity for entrepreneurship. 相似文献

We introduce a new type of heavy‐tailed distribution, the normal reciprocal inverse Gaussian distribution (NRIG), to the GARCH and Glosten‐Jagannathan‐Runkle (1993) GARCH models, and compare its empirical performance with two other popular types of heavy‐tailed distribution, the Student's t distribution and the normal inverse Gaussian distribution (NIG), using a variety of asset return series. Our results illustrate that there is no overwhelmingly dominant distribution in fitting the data under the GARCH framework, although the NRIG distribution performs slightly better than the other two types of distribution. For market indexes series, it is important to introduce both GJR‐terms and the NRIG distribution to improve the models’ performance, but it is ambiguous for individual stock prices series. Our results also show the GJR‐GARCH NRIG model has practical advantages in quantitative risk management. Finally, the convergence of numerical solutions in maximum‐likelihood estimation of GARCH and GJR‐GARCH models with the three types of heavy‐tailed distribution is investigated. 相似文献

This study examined how entry‐level employees interacted with social media during three stages of organizational socialization. They navigated between four different media affordances (persistence, editability, visibility, and association) while experiencing them as both enabling and constraining in different socialization stages. Qualitative interview data analysis revealed during anticipatory socialization, job applicants realized visibility and persistence in relation to institutional and individualized socialization. During encounter, new employees managed personal and professional life boundaries carefully against the association and visibility affordances. Although some participants used both public and enterprise social media for obtaining job‐related information and understanding coworkers and company culture, during metamorphosis, most interviewees adopted passive information seeking strategies and experienced a paradoxical tension between the enabling and constraining affordances of social media. Findings are discussed with regards to employees’ exertion of agency in managing their professional impressions and coping with high levels of uncertainty and vulnerability during early stages of socialization. 相似文献

中国城镇化进入了以提升质量为特征的减速阶段,农民工有序完成迁移第二个过程,即在城市定居下来,这是高质量城镇化的重要组成部分,而快速上涨的城市房价对农民工定居意愿的影响日益凸显.本文首先构建中国城乡人口迁移两个过程的理论模型,分析城市住房价格对农民工定居意愿的影响及作用机制;其次将2012-2017年中国流动人口动态监测数据与288个城市数据匹配进行实证检验.研究发现,城市高房价显著降低了农民工的定居意愿,而定居意愿下降将会阻滞城镇化的进程.机制检验发现,城市高房价主要通过提高农民工家庭在城市的预期购房成本进而降低其定居意愿.此外,本文还进行了个体异质性和城市异质性检验.个体异质性检验发现,城市高房价对第二代、低受教育水平和本地无房农民工定居意愿的负向影响更大,对更高收入水平、更大发展空间以及可获得公共服务农民工定居意愿的负向影响更小;城市异质性检验发现,随着城市规模的扩大,城市高房价对农民工定居意愿影响的负向作用逐渐增大.本文的政策含义是抑制城市房价过快上涨、提高农民工收入和福利水平、提供更为平等的公共服务,以及解决好进城农民工"三权"有偿退出问题,可以增强农民工的定居意愿,推动城镇化高质量发展. 相似文献

主流经济学家把改革开放后民营企业的大规模兴起,主要归因为市场经济条件下发挥企业家精神和遵循比较优势的必然结果。但是这无法解释为什么民营企业在兴起之初就广泛和快速地进入到各个工业,尤其是技术和资本密集型工业。基于中国工业史和252家中国最大民营制造业企业创业发展史的历史证据,文章找回"工业体系"这一被主流所忽略的重大历史现象和学术概念,从而首次提出一种理解中国民营企业发展独特性的结构性解释。文章发现:从计划经济时期继承而来的门类齐全和独立完整的工业体系,是解释民营企业创业和发展独特性的关键变量;已有的由国有企业和科研院所组成的工业体系,从市场机会、技术能力和组织资源等方面塑造了民营企业的创业选择和发展路径。所以,中国民营企业的快速发展不是仅凭自由市场就会自动出现的普遍现象,而是在市场条件下充分利用工业体系提供的技术和市场条件才得以出现的特殊现象。 相似文献

Following the approach of interpolation, this paper proposes the multiple exponential decay model to fit yield curves for both the U.S. TIPS market and the conventional Treasury security market. Several estimation methods, including the unconstrained/constrained nonlinear minimization, quadratic programming, and the iterative linear least squares, are applied to estimate the unknown parameters according to different curve‐fitting purposes. Comparisons between the proposed model and the alternatives show that the multiple exponential decay successfully (1) adapts to a variety of shapes associated with yield curves, (2) (partially) keeps in line with the economic interpretations of Nelson–Siegel summarized by Diebold and Li ( 2006 ), and (3) dominates the competing models in curve‐fitting performance measured by mean fitted‐price errors over the sample period. In addition, the exact specification of a nonparametric interpolation model is pinned down by applying three statistical tools, which enable us to jointly take into account validity, optimality, and parsimoniousness of the proposed model. 相似文献

所有权与经营权的分离是现代企业的基本特征,内部人控制问题已成为制约上市公司健康稳定发展的瓶颈因素。本文通过建立一个CEO、董事会和外部监管机构三方之间的博弈模型,强调了监管的重要性;并从完善董事会职能和加强外部监管力度两个方面对上市公司CEO的道德风险之监管提出合理性建议。 相似文献
