On the Role of Futures Trading in Spot Market Fluctuations: Perpetrator of Volatility or Victim of Regret?

We examine the role of index futures trading in spot market volatility. We use the exponential generalized autoregressive conditional heteroskedasticity (EGARCH) approach to measure volatility, analyze causality and feedback relations between volatilities in the spot and futures markets, and test various hypotheses in the context of a multivariate model that incorporates other macrostate variables. Our empirical results suggest index futures trading may not be blamed for the observed volatility in the spot market. Rather, we find stronger and more consistent support for the alternative posture that volatility in the futures market is an outgrowth of a turbulent cash market. We use the regret (cognitive dissonance) theory to explain our results.

对天津市服务业发展的几点思考与建议

近年来,天津市服务业总体呈现出持续健康、快速发展的态势,服务业的地位和作用日益提升．对经济发展的贡献度不断增强,空间布局逐步趋向优化,天津市服务业已经进入了一个新的上升阶段。同时,我们也看到,与国际大都市相比,天津市服务业的总体规模还比较小,产业集聚度偏低,资源配置功能比较弱．产业结构还要进一步优化。天津市经济发展面临着经济总量提高和服务业比重提升的双重压力．据此．本文对天津市服务业的发展提出思考与建议。     

论创意产业成长的生态环境

创意产业的兴起是我国经济转型的一种必然选择。处于成长期的创意产业,存在产业链欠完整、资金制约突出、知识产权缺乏有效保护、抗风险水平低等问题。改善我国创意产业成长的生态环境,需要经营者提升自身素质,也需要行业组织在组织、协调、服务中为其排忧解难,需要政府在建立产业链、加强金融支持、健全法律法规、改善教育等方面,提供更多的政策和管理扶持。     

Migrate or not? The effects of regulation SHO on options trading activities

In this study, we investigate the effects of stock short-sale constraints on options trading by exploiting two US Securities and Exchange Commission rule changes under Regulation SHO: Rule 203 (locate and close-out requirements) and Rule 202T (temporary removal of short-sale price tests). We find that stock short selling activities decrease (increase) significantly after Rule 203 (Rule 202T) implementation, supporting the validity of Rule 203 (Rule 202T) as an exogenous increase (decrease) in short-sale constraints. Options volume increases significantly after Rule 203 went into effect and the result is more pronounced among firms with lower levels of institutional ownership and smaller options bid-ask spreads. Therefore, the evidence from Rule 203 suggests that investors may use options as substitutes for stock short sales when short selling is less feasible or more costly due to the locate and delivery requirements. In contrast, we find no significant change in the options trading volume of pilot stocks during the pilot program of Rule 202T. Overall, our results indicate that the impact of short-sale constraints on options trading varies with the types of constraints affected.     

Sense of belonging,international migrants’ spending,and implications for their subjective well-being

A lack of a sense of belonging in the host country has become one of the most common challenges facing international migrants in today's sociopolitical environment. Our two online experiments with 881 international migrant workers in the United States jointly demonstrate that, to cope with their lack of a sense of belonging in the host country, international migrants may spend money suboptimally: more on material purchases but less on experiential and prosocial purchases. More importantly, our studies suggest that prosocial purchases are more effective than experiential purchases in increasing international migrants’ subjective well-being. This is because prosocial purchases can lead to both relatedness need satisfaction and beneficence, with each independently contributing to international migrants’ subjective well-being. Our research suggests that public policymakers should address the social exclusion international migrants experience when moving to a new country because it can have a negative impact on their subjective well-being. Our research further suggests that one way to mitigate social exclusion is to encourage international migrants to spend money on others rather than themselves.     

省直管县改革与区域空气污染——来自卫星反演数据的实证证据

从政府治理结构改革的角度探讨如何推进环境污染治理是一种有益的尝试。从理论上来说,省直管县改革作为一种重要的政府治理结构改革,能够通过简化政府治理级次来改变政府治理效率,影响诸如环保等公共产品和服务的供给。本文采用卫星反演的PM2.5数据检验了省直管县改革前后县级区域空气污染的变动趋势。发现“财政省直管县”改革能显著降低地区空气污染水平,“强县扩权”改革则显著加剧了地区空气污染。稳健性检验、进一步的分析结果均支持上述结论。机制检验发现,“财政省直管县”主要体现为财力保障水平提升导致的治理变化,而“强县扩权”则主要体现为地方政府竞争行为改变导致的空气污染治理变化。总之,单纯的政府级次减少可能并不必然利于地方公共服务的提供,良好的财力保障为地方污染治理服务提供了支撑,竞争行为变化带来的改革效应则会受到政府对环境污染重视程度的显著影响。
