Childhood adversity and the propensity for entrepreneurship: A quasi-experimental study of the Great Chinese Famine

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.     

EMPIRICAL PERFORMANCE OF GARCH MODELS WITH HEAVY‐TAILED INNOVATIONS

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.

基于Panel—Data模型的山东省区域旅游问题研究

旅游业已被公认为“朝阳产业”、“无烟工业”，是集吃、住、行、游、购、娱为一体的综合性很强的产业，其光明的发展前景已为世人所公认。旅游业对其相关产业的牵动比例为1：4，可以充分带动地方经济的发展，发展潜力很大。本文运用了山东省17地市的国内旅游情况的合成数据，通过建立完整的计量模型，进行计量分析，进而发现各地市每增加一万人次的旅游者，对该地区的旅游经济的影响存在一定的差异，并且对于差异进行聚类分析，得出全省各地市的不同属类，为山东省日后旅游市场的更好发展提出了一些相应的建议。     

证券基金淘汰与反淘汰问题的初步研究

我国证券投资基金在经历了初期“繁荣”之后，目前已进入市场化淘汰时期。文章首先指出我国证券基金逐渐露出的若干淘汰信号，进而从内外部（即主客观）两大方面分别审视其淘汰成因，最后落脚到详尽拟定反淘汰对策上来。文章首开证券基金淘汰与反淘汰问题的研究，不仅是为理论创新，更是为它的可持续发展提供实践依据。
