Are social entrepreneurs more risk-averse?

We have a conventional wisdom that risk-seeking behaviours are related to commercially oriented entrepreneurs. For this reason, most studies have focused on the context of commercial entrepreneurship, and thus we do not know the risk propensity of social entrepreneurs. Using the PSM method, contrary to our wisdom, we find that social entrepreneurs tend to more have about 15% risk-seeking propensity than commercial entrepreneurs.     

Positive feedback trading and long-term volatility links: evidence from real estate markets of USA,Be/Lux and Switzerland

This article investigates the positive feedback trading strategies in the real estate markets of USA, Belgium/Luxembourg (Be/Lux) and Switzerland, linking these strategies with long-term volatility. The results are in favour of a positive feedback trading strategy which negatively influences investors' risk-return position on real estate markets.     

金融自由化、经济转轨与农民相对贫困的恶化

金融自由化通过如下机制影响农民相对收入水平:经济增长、金融服务、金融发展和金融危机。转轨经济的特殊性使上述4个渠道都使农民相对收入增长受到不利影响。经济增长的再分配效应是不确定的。在转轨过程中,国有经济和国有银行从农村地区大规模撤退,减少了农民的金融机会和金融服务。在金融发展过程中,农民分享经济增长和金融发展外部性的难度提高。金融危机的再分配效应更是不利于农民。综合效应是,伴随金融自由化的推进,农民金融机会集合变窄,城乡收入差距快速扩大。     

Vertical alliance portfolios and the business performance of small technology-based firms

This paper discusses how small technology-based firms (STBFs) effectively manage vertical alliances by choosing proper alliance structures to both manage challenges and pursue higher performance. We consider the main challenges of STBFs’ vertical alliances as opportunistic risk and coordination concern between partners, and derive four types of vertical alliance portfolios with different extents of risk and return based on the relational perspective. We then examine the impact of each portfolio on performance and the moderating effect of STBFs’ age and technological capability. The results show the portfolio focusing on bilateral alliances is not helpful for STBFs, while the others are useful. The portfolio focusing on unilateral alliances promises young firms better performance, while hybrid portfolios of unilateral and bilateral alliances are more helpful for older STBFs. In hybrid portfolios, bilateral alliance in the upstream is beneficial to specific technology-focused firms, while bilateral alliance in the downstream is recommended to STBFs whose technology covers a wider range.     

Financial risk attitudes and aging in Australia

A number of empirical studies document that people tend to become more risk averse as they get older. But other studies find only little evidence that age matters for financial risk attitudes. This prompts a call for revisiting the relationship between age and risk attitude to better support policy recommendations. The current paper contributes to this effort by utilising large-scale population data to conduct a dynamic panel analysis. Care is taken to avoid the problem of endogeneity of lagged risk attitude in modelling its effects. Analysis reveals that individuals' past risk attitude has a positive effect on their current risk attitude. However, there is only little evidence that risk attitude and age are systematically related. Our results shed some light on the previous contradictory empirical findings in the literature and suggest that past risk attitude is potentially of greater relevance than chronological age in determining current risk attitude.     

规划理论和实践中的空间观念辨析

规划理论和实践中的空间观念塑造着我们周围的人造环境。空间观念的发展呈现出从绝对到相对、从时空分离转向时空关联、从一元到多元的变化趋势。20世纪以来规划理论逐渐吸纳相对空间观念,但迄今为止规划实践仍以绝对空间观念为主导。绝对空间观念成为规划实践低效性的深层原因,但是完全放弃绝对空间观念而将相对空间观念引入规划理论和实践不仅存在很多困难,而且会造成认识和实践上的混乱,科学的空间观念应该将绝对和相对结合起来形成多元空间观。我国规划理论研究和实践仍以绝对空间观念为主导,了解绝对空间观念的不足和吸纳相对空间观念的合理性具有重要的理论和实践意义。     

制造企业新产品开发构思阶段风险评估研究

制造企业的新产品开发是个复杂的系统工程,不仅耗资多、难度大,而且风险性高,在开发过程中经常会出现众多不确定因素,导致新产品开发的失败.分析制造企业新产品开发构思阶段的风险因素与特征,构建有效的风险评估指标体系,采用模糊评价法,对A企业新产品开发构思阶段进行风险评估并提出相应对策,从而降低企业新产品开发风险,提高新产品开发成功率,这对我国企业新产品开发决策具有重要的指导意义.     

我国人口流动与中央财政转移支付相对力度的区域差异分析

为了缩小东中西部地区的发展差距,中央财政加大了对中西部地区的转移支付力度,但在促进区域经济发展收敛和实现地区财政均等化方面其效果如何,文章试图从一种新的视角加以分析与诠释。改革开放以来大规模的人口跨地区流动,特别是年轻劳动力从中西部地区向发达的东部地区流动,改变了各地区的人口结构和总扶养比,进而影响中央财政转移支付的实际效果。研究结果表明,由于西部地区总扶养比高于东部地区,中央财政对西部地区的转移支付相对力度反而低于东部地区。文章最后提出将地区人口负担差异纳入中央财政预算分析体系,通过增加中央财政对经济落后地区的转移支付促进地区经济增长收敛和提高地区财政帮扶的实效性。     

基于熵权的信息工程监理风险评估

本文利用模糊评判方法对信息工程监理进行风险评估，对各风险因素分别从风险发生的概率和风险产生的影响两方面进行评估。采用熵权系数法对风险因素的权重进行客观计算，克服了专家评判的主观性。通过实例分析表明该方法是有效和实用的。     

火电项目融资的现金流量风险评价——基于探索图的指标体系

已有关于火电项目风险的研究基本未重点考察现金流量风险。本文从火电项目融资的角度出发,发现现金流量风险的重要性,尝试性地运用复杂科学管理系统思维的工具——探索图,为火电项目的建设期、试生产期和生产运营期分别建立风险评估指标体系,并用动态模糊评价方法确定每期和全过程的现金流量风险程度,为火电项目融资决策提供依据。
