Disentangling the migration-trade nexus: the pro-trade effects of immigrants and emigrants in the presence of vertical and horizontal product differentiation

This paper presents an exploration of the migration-trade nexus taking the case of Italy by crossing the two dimensions of migration (immigration and emigration) and the two dimensions of intra-industry trade (vertical and horizontal). This empirical strategy proves useful in refining interpretation of econometric results. In general, we find that both immigration and emigration are positively and significantly related to intra-industry trade. However, the magnitude and the statistical significance of the impact of migration on trade vary, depending on the type of trade flows considered (vertical or horizontal), the direction of migration (immigration or emigration) and the partner countries considered (OECD or non-OECD). In particular, we find that immigrants from non-OECD countries have a positive and significant impact on both ‘variety trade’ and ‘quality trade’, while immigrants from OECD countries significantly affect ‘variety trade’ only. Emigrants to non-OECD countries have positive effect only on ‘variety trade’. These findings are largely consistent with predictions deriving from theoretical models of intra-industry trade and from the literature on migration-trade nexus.     

Economic integration and growth under intergenerational financing of human-capital formation

This paper examines the patterns of economic integration and endogenous growth in a two-country overlapping-generations world, in which the formation of children's human capital is financed by parents. It explores the influence of cross-border external effects in human capital on growth. Interestingly, world integration can enhance (reduce) long-run growth in both countries if cross-border external effects in human capital are sufficiently strong (weak).     

物流业与区域经济一体化协调发展的实证及理论解释——基于中国省级数据的分析

在分析我国物流业发展对区域经济一体化的作用机理的基础上,利用我国29个省(自治区、直辖市)的省级数据,通过相关分析与回归分析,实证研究了我国省级物流业的发展水平,检验了物流业发展水平与区域经济一体化程度之间的相关性。实证结果表明:物流业的发展水平与省际贸易壁垒之间存在负相关关系;区域经济一体化能促进物流业的发展,物流业的发展有助于降低我国省际贸易壁垒、缓解国内市场分割状况、推进省际贸易发展和实现区域经济一体化;东南沿海地区省份与中、西部地区省份在物流基础设施与贸易依存度方面存在明显差别。     

中欧服务业产业内贸易实证研究

由服务贸易的比较优势和产业内贸易研究概况,引出对中欧服务业产业内贸易的实证分析。基于2004～2009年中欧服务贸易数据测算出GL指数和MIIT指数,发现了各服务部门产业内贸易发展的不同态势。选取人均GDP、服务贸易开放程度和对外贸易不平衡程度作为自变量,即影响因素,但均未表现出与产业内贸易指数较强的相关性。     

The global economy--myths and realities

Hirst and Thompson's Globalization in Question is the key textquestioning claims of economic globalisation. This review ofits revised second edition examines its main claims: that contemporarylevels of international integration fall short of the Gold Standardperiod; genuinely global companies remain exceptional; capitalmobility is not shifting economic activity to developing countrieswholesale; international economic activity is primarily regionalrather than global; and that international economic activityis sanctioned by nation states and remains subject to theirpolitical power. This review argues that, while their evidenceprovides a useful corrective to extreme globalisation views,focusing on this view understates changes in the internationaleconomy.     

中美农产品加工业产业内贸易影响因素研究

分析了中美农产品加工业贸易状况,并对两国农产品加工业产业内贸易的影响因素进行了实证研究。结果表明,近年来中美农产品加工业贸易快速发展;而中美贸易不平衡对两国农产品加工业产业内贸易起到了显著的抑制作用,同时中美两国人均GDP差异、行业开放程度则较强地促进了两国农产品加工业产业内贸易的发展。基于此,中国应侧重提升中美农产品加工业产业内贸易水平,实施产业间贸易和产业内贸易双轮驱动战略。     

Temporary Migration, Human Capital, and Language Fluency of Migrants

This paper investigates human capital investment of immigrants whose duration in the host country is limited, either by contract or by their own choice. The first part of the paper develops a model which distinguishes between temporary migrations where the return time is exogenous or optimally chosen. The analysis has a number of interesting implications for empirical work, some of which are explored in the second part of the paper. The analysis focuses on language capital and tests the hypothesis that country specific human capital investments are sensitive to the duration in the host country's labour market. The results show that the acquisition of language capital is sensitive to the intended duration in the host country.     

对外贸易、FDI的经济增长效应与环境污染效应实证研究

外贸与FDI都在整体上促进了中国经济增长,其中,进口对经济增长的作用较小;出口与FDI加剧了中国环境污染;进口贸易可抑制环境污染,但作用比较小;人力资本具有显著的促进经济增长与抑制环境污染的双重功能。     

人力资本结构对经济增长贡献率的实证分析

建立人力资本结构对经济增长贡献率的计量模型,采用相关数据对该模型进行实证分析。结果表明：中等教育对我国经济增长的贡献率较高,高等教育相对较小。因此,建立模型分析不同受教育年限的人力资本对经济增长的贡献率就非常具有现实意义。     

International migration,economic policy and human capital accumulation: a simulation study

"This paper examines the economic policy implications of international migration and human capital accumulation within a dynamic general equilibrium model. Each country produces by means of physical and human capital of two types (skilled and unskilled labour). Along optimal growth paths in a world of diverging population growth rates immigration can only be beneficial when the free rider effect (i.e., not paying for training costs) exceeds the capital dilution effect of an increase in population growth. Under quite general conditions the optimal immigration rate is zero."     

中国人口、人力资本变化趋势

利用多状态人口预测模型,以2000年人口普查为基础数据,在对数据进行评估和修订的基础上,综合相关研究成果对未来生育水平、死亡水平、人口迁移和教育转换等参数进行估计,预测了2000年到2030年人口规模的变化,对未来人口的年龄结构特别是老龄化和未来人口和劳动年龄人口的人力资本进行了预测,并分析了城市化和人口迁移对我国未来人口发展的影响。预测结果对我国编制人口规划、制定应对老龄化、提高人力资本和合理利用劳动力的有关政策具有重要意义。     

上海市未来人口和人力资本的变化趋势分析

利用多状态模型,预测了上海市未来30年人口规模、年龄结构、城市化水平,以及人力资本的变化趋势。无论从上海市经济发展对于劳动力的需求,还是上海市的人口结构看,一定数量的迁移人口对于上海经济和人口的健康发展是有积极意义的。
