Linking young individuals' capital to investment intentions: Comparing two cultural backgrounds

By integrating the Entrepreneurial Intentionality Model and the Theory of Planned Behaviour, we explored the effects of human, social and financial capital on young individuals' investment intentions in two groups (97 English and 97 Greeks). Results indicated that human capital is directly and indirectly related to investment intentions via, first, subjective norms and, consequently, personal attitudes and perceived behavioural control, while social capital is only indirectly related to investment intentions via perceived behavioural control. In the individualistic group (English), human capital related directly and positively with investment intentions while social capital related indirectly to investment intentions via its positive relationship to subjective norms. With regard to participants from a collectivistic background (Greeks), human capital related indirectly to investment intentions via, first, subjective norms and, consequently, personal attitudes and perceived behavioural control, while social capital related directly and indirectly to investment intentions via perceived behavioural control. Financial capital was only negatively related to investment intentions in the total and Greek sample.     

外资法的选择:南非改革《投资保护法案》

国际投资体系正在遭遇危机，越来越多的国家开始质疑双边投资协定提供的投资者保护制度是否确实有益于增加投资的流动，全球多个国家正在审慎地进行外国投资法的改革。基于此，文章以南非的实践为现实起点，通过概述南非投资保护制度变革的缘由以及深入剖析《投资保护法案》的立法意图，阐明其以国内立法维护公共利益监管权力的法律选择，旨在“一带一路”背景下，为远赴南非的中国投资者提供法律风险的预判，揭示外资法变革对于中国投资者可能产生的影响。对于南非建立新的投资保护制度，其将面临的挑战是如何维持稳定、可预测的投资环境与实现投资保护改革的若干目标之间的平衡。      

The coevolution of trade agreements and investment treaties: Some evidence from network analysis

Regional trade agreements (RTAs) and bilateral investment treaties (BITs) are expected to promote trade and investment relationships. One critical feature of such agreements is the network, so the multiplex coevolution of RTAs and BITs should be captured by the dynamics of their two networks. Although many studies have examined the roles of RTAs and BITs, most studies do not account for crucial network properties. This study explores how RTAs and BITs coevolve by applying a stochastic actor-oriented model of multiplex network evolution. In particular, we examine the roles of (i) cross-network dyadic interinfluences and (ii) within- and cross-network preferential attachments to discuss the dynamic relationships between RTAs and BITs. The results are as follows. First, our estimation supports cross-network dyadic interinfluences. Countries that sign a BIT are willing to establish an RTA, while those that sign an RTA are reluctant to establish a BIT. Second, concerning preferential attachments, countries prefer to sign BITs with partners that have more RTA and BIT links. However, countries tend to form RTAs with partners that have more BIT links but are reluctant to form RTAs with those that have more RTA links. We discuss possible justifications for these results, including arguments regarding the benefits and costs associated with the formation of RTAs and BITs.     

科技研发投入政策模拟分析：基于中国科技CGE模型

从经济系统论角度,基于最新投入产出表和我国科技研发投入情况,编制中国科技社会核算矩阵,构建中国科技研发可计算一般均衡（CNT-CGE）模型,并模拟分析调整政府支出结构和科研经费制度改革两项科技研发投入政策。结果显示：调整政府支出结构政策可以使得实际GDP 增长率随着政府消费降幅的增加而增加,GDP 平减指数则随着政府消费降幅的增加而减少,其绝对降幅略小于实际 GDP 增幅;科研经费制度改革政策可以有效地提高我国 GDP 增长率,显著地降低物价水平,提升社会整体福利水平。     

试论1930年代商业银行对农村的投资活动--围绕农村合作社的探讨

1930年代商业银行对农村的投资是在都市银行剩余资金膨胀、农村金融需求加剧的情形下展开的。这一时期农村合作社的迅猛发展为商业银行在农村投资开辟了一个极好的渠道。商业银行通过农村合作社投资农村,对于调剂农村金融、挽救濒于崩溃的农村经济起了一定的积极作用,但由于商业银行的这一投资活动并非出于“救济农村”的本意,又使其不可避免地具有一定的历史局限性。     

从收入分配和经济发展的角度看我国的最低工资制度

本文基于我国的一些特殊的国情,从动态的视角出发,讨论了最低工资制度对我国收入分配格局和经济发展的影响.本文研究认为,由于我国特殊的国情,一种合适的最低工资制度在我国可能会产生以下三种效应:第一,最低工资制度具有改善我国收入分配格局,缩小收入差距的功能;第二,一个各地区有差别的最低工资限制可能会促进我国的产业结构向内地转移,促进我国的产业结构升级;第三,长期来看,最低工资限制可能会强制低人力资本工资进行人力资本投资,有助于我国人力资本的提升.     

基于2007年投入产出表的我国投资乘数测算和变动分析

 本文对固定资产投资乘数、凯恩斯投资乘数和投入产出投资乘数等三种投资乘数进行了测算分析,结果表明近年来我国投资乘数并没有发生大幅度下降,对经济增长的拉动贡献较大。通过对4万亿投资计划的具体测算,表明投资对拉动内需和抵御外部冲击发挥了巨大作用。作为发展中国家,保持较高的投资增速是经济可持续发展的必要条件,未来投资仍将是拉动我国经济增长的主要动力。但应当积极调整投资结构,避免产能过剩、抑制房地产价格上涨,提高投资效率。     

关于城乡教育投资收益率的比较

本文对城乡教育投资收益率进行了分析及比较。本文主要结论:(1)因城乡人口流动性大,定量估算的横截面教育收益率不能代表城乡居民真实收益率,利用其作经济分析应十分慎重;(2)农民由于收入较低只能在较高的边际收益率下停止对子女教育支出,所以农民的家庭教育支出较少,收益率反而较高,因此更多教育资本向农民倾斜将提高全社会经济效率。     

海合会国家主权财富基金的发展及其影响

海合会国家热衷于建立各类主权财富基金,他们在基金的管理、运作透明度、投资战略和模式等方面均具有鲜明的特色。在美国次贷危机后,这些基金在跨国投资方面表现更为积极,直接导致了投资接受国加强投资审查等限制性措施。投资接受国政策的演变以及2009年的迪拜债务危机对海湾国家主权财富基金未来发展均产生了深远的影响。     

Uniform Tail Asymptotics for the Sum of Two Correlated Classes with Stochastic Returns and Dependent Heavy Tails

Consider a continuous-time risk model with two correlated classes of insurance business and risky investments whose price processes are geometric Lévy processes. By assuming that the correlation comes from a common shock, and the claim sizes are heavy-tailed and pairwise quasi-asymptotically independent, we investigate the tail behavior of the sum of the stochastic present values of the two correlated classes, and a uniform asymptotic formula is obtained.
