International capital market integration: Implications for convergence, growth, and welfare

This paper studies the effects of international capital market integration on welfare and the speed of adjustment in a two-region endogenous growth model. Monopolistic firms undertake research and development (R&D) to improve their productivity level. National and international knowledge spillovers affect the returns to R&D. The two countries differ with respect to the initial productivity level and R&D capability (which is a proxy for human capital and structural policies). Long-run productivity gaps are determined by the difference in R&D capability. Over time, there is conditional convergence in productivity levels. The speed of convergence is larger with integrated international capital markets than without. Long-run gaps in consumption levels are larger in the former situation than in the latter. Capital market integration harms (benefits) the leading (lagging) region if domestic spillovers are more important than international spillovers and differences in R&D capabilities are small.The authors research is supported by the Royal Netherlands Academy of Arts and Sciences.

Where to park? A behavioural comparison of bus Park and Ride and city centre car park usage in Bath,UK

Integrating car parking facilities with public transport in Park and Ride (P&R) facilities has the potential to shorten car trips, contributing to more sustainable mobility. There is an ongoing debate about the actual effects of P&R on the transport system at the subregional level. A key issue is the relative attractiveness of city centre car parks (CCCP), P&R and public transport. The paper presents the findings of a comparative empirical case-study based on a field survey of CCCP and P&R users conducted in the city of Bath, UK. Spatial and statistical analyses are applied. Radial distance to parking, availability of P&R sites in the direction of travel, gender, age, income and party-size are found to be important factors in a binary logistic regression model, explaining the revealed-preference of parking type. Stated analysis of foregone parking alternatives suggests more use of public transport and walking/cycling would likely occur without first-best parking alternatives. The policy implications and possible planning alternatives to P&R at the urban fringes for achieving greater sustainability goals are also discussed.     

劳动力流动限制下的经济增长

传统自给自足农业经济向现代农业与工业分工的经济转变过程,内生了经济增长和劳动力向非农产业的流动。在新兴古典经济学模型的基础上,加入劳动力流动限制的条件,构建两种商品的一般均衡经济增长模型。模型显示：交易效率足够高时,经济增长与劳动力流动都是分工的结果;劳动力流动限制并不影响经济增长的效果,只产生收入差距效应。实证结果支持这一判断,劳动力流动与经济增长不存在因果关系。     

国有部门与非国有部门的工资差异及影响因素研究

基于CGSS数据,利用Heckman样本选择模型对中国国有部门与非国有部门的工资差异和影响因素进行系统研究。回归结果显示,国有部门员工的教育收益率高于非国有部门,教育收益率与学历水平呈现正相关关系,与非国有部门相比,国有部门中大学本科及以上学历员工的教育收益率更高。工资差异分解结果表明,两部门全样本工资差异中市场歧视占比高于特征差异占比,与全样本相比,大学本科及以上学历员工的工资总差异和特征差异占比更高,系数差异占比更低,说明高学历群体中部门间工资差异更为明显,而且两部门中仍存在较严重的劳动力市场分割和就业歧视问题。因此,政府应努力消除劳动力的流动性障碍,深化国有部门市场化改革,制定更为合理的工资机制,以促进中国经济的持续健康稳定增长。     

人口新常态约束下特大城市的规模调控与转型升级

不同国家、不同历史时期的特大城市人口规模变动极大,运用 Kernel 密度函数对中国城市人口规模分布的分析表明,当前以城区常住人口“500万以上”为特大城市的划分标准是合理的。从城市人口规模变动的动态历程来看,该变动主要受城市产业与经济发展的影响。对中国主要特大城市实有人口规模变动的分析表明,特大城市的人口规模调控应因时因地而动,不能搞一刀切,而且人口调控政策重点应该从数量控制转向结构优化。特大城市转型升级面临着农民工供给短缺、大学毕业生相对过剩、老年和少儿非劳动力人口持续增长等人口新常态约束。在这种人口增长新常态背景下,特大城市应坚持市场化改革方向,促进政府制度创新和企业技术与管理创新是城市转型升级的根本动力。     

中国城乡劳动力流动影响因素研究——理论模型与实证分析

结合中国实际情况,对哈里斯-托达罗模型的基本假设进行修定,从农民追求预期净收益现值最大化出发,运用动态宏观经济学的递归方法,推导出均衡条件下中国城乡劳动力流动影响因素的理论模型,并采用动态面板计量方法实证检验各影响因素对城乡劳动力流动的作用方向和程度。研究发现：城乡劳动力流动率的滞后值、城乡实际收入差距、非农产值比和农业比较劳动生产率对城乡劳动力流动有正的影响,但城乡实际收入差距的影响系数值偏小;城镇失业率、城乡消费支出比和农村工业化对城乡劳动力流动有负的影响;制度变迁和全社会固定资产投资率对城乡劳动力流动也有一定程度但不显著的正影响。为了解决农民工就业问题,应加强城乡联动共同发展。     

向上社会流动预期对个体捐赠意愿的影响研究

随着经济社会的快速发展和公民慈善意识的不断提升,慈善捐赠已成为促进社会公平、实现共同富裕的重要途径,但影响个体慈善捐赠意愿的关键因素尚待深入探究。本研究结合宏观社会结构视角,以社会流动预期为切入点,利用SOR 理论构建“向上社会流动预期—慈善情感—个体捐赠意愿”理论分析模型。通过对411 名捐赠者进行问卷调查,采用偏最小二乘结构方程法分析数据,研究发现：向上社会流动预期对个体捐赠意愿具有显著正向影响;同情心、幸福感和感恩在向上社会流动预期与个体捐赠意愿的关系中起到显著中介作用;三种慈善情感的中介效应存在差异,其中同情心的中介效应最强。本研究整合社会结构、个体心理和行为意愿三个层次,丰富了决策行为理论研究,为公益实践提供新视角,对推动共同富裕具有重要意义。
