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.     

Does trade creation by social and business networks hold in services?

Recent literature on the border effect has shown that the intensity of trade in goods is positively correlated with the migration stocks between any pair of countries/regions. The number of references for business networks is more limited, but they are also related with a reduction on information costs. In this article we investigate whether such a relation holds also for Spanish domestic trade flows in consumer services. To this end, we use a gravity model rooted in the Dixit–Stiglitz–Krugman theoretical framework and a unique data set on interregional trade flows for some of the main tourism service sectors, namely, accommodations and restaurants. Our industry-specific analysis finds a large positive effect for restaurants but a more limited effect for accommodations. Forces driving the demand in each sector explain this result and suggest the idea that although social networks can act as a substitute of firms in some sectors at the same time they can enhance trade flows in other sectors. We perform the same kind of analysis with a data set (obtained by a similar method) for domestic trade in goods and discover a different response to social and business networks. Finally, we treat the potential endogeneity by taking the instrumental-variable approach of the Poisson pseudo-maximum likelihood estimator and thus obtain consistent results.     

国际贸易与城市化的相关性及其贡献的计量研究

国际贸易与城市化均属于资源在空间和产业维度的配置过程,二者通过工业化发生联系.中国的工业化表现为劳动力的非农化,工业产值与城市化水平之间存在耦合关系.本文建立了开放条件下工业化内生决定的城市化模型,从而为计算国际贸易对城市化水平的贡献提供了比较静态的分析方法.研究表明,国际贸易是推动中国城市化快速发展的重要因素.     

中国服务贸易在世界地位的实证研究

近年来我国的服务贸易总量已经位居世界前列,那么是否服务贸易的竞争力也是名列前茅呢?为了对我国服务贸易的国际竞争力进行比较全面的分析和评价,笔者对我国服务贸易的进行了多角度的比较分析.首先,从其自身发展的过程来看,自2000-2010年我国服务贸易一直是不断处于增长,且其增速水平超过了世界服务贸易的平均增长水平,但是仍然处于逆差地位,贸易结构也是以传统的服务贸易为主,说明我国服务贸易一方面是由于我国经济的飞速发展对服务贸易进口的需求不断提高,另一方面也说明我国的服务贸易竞争力处于相对弱势地位,竞争力有待提高.同时,本文对2000-2010年期间服务贸易和货物贸易的发展作了比较,相对于货物贸易来说,我国服务贸易的发展还是相对落后,处于弱势地位.第二部分,本文运用了贸易竞争力指数、显性比较优势指数和显示性比较优势指数等指标对我国的服务贸易竞争优势进行定量分析,指标数据显示我国服务贸易的竞争力在世界处于弱势地位,其提升道路任重而道远.     

世界双边自由贸易发展趋势与我国应对策略

随着世界经济全球化进程的加快，世界经济区域化、一体化进入了以双边自由贸易为主的新阶段。作为贸易与自由化的一种现实选择，双边自由贸易的发展，既是对区域经济一体化的补充和推动，也是世界经济一体化的新动力。为此，我国就要在逐步兑现加入WTO的承诺，降低关税的同时，积极加强双边自由贸易合作，以持续保持我国对外贸易发展的优势。     

Wage and Mobility Effects of Trade and Migration on the Austrian Labour Market

This study analyses the effect of trade and migration on wages and labour marketmobility. We estimate wage growth equations and a multinomial logit mobilityequation on an individual data set ranging from 1991 to 1994. We find substantialdifferences in the reactions of white and blue-collar workers wages and mobilityto trade and migration. In Austria exports have a positive and imports a negativeimpact on wage growth only for blue-collar workers. Migrants also reduce onlyblue-collar workers wage growth. Our results indicate that higher imports and aninflow of migrants reduce sectoral mobility of all types workers. The risk of beingout of work by contrast is increased by migration and imports only for blue-collarworkers, but reduced by exports for all types of workers. In general our results suggestenlargement of the EU would have only small effects on the Austrian labour market.     

欧美和中国对技术性贸易壁垒的研究综述

鉴于技术性贸易壁垒对世界经济和国际贸易的重要影响,各国学者都对技术性贸易壁垒问题进行了大量研究,并取得了丰硕的成果,这为相关国家和地区的政策制定提供了很好的决策参考。欧美发达国家是技术性贸易壁垒的发祥地,也最早从事技术性贸易壁垒研究。早在19世纪60年代,欧共体就意识到技术性贸易壁垒对国际贸易的限制作用,并于1969年制定了《消除商品贸易中技术性壁垒的一般性纲领》,第一次提出了在国际贸易中制定技术性贸易壁垒的贸易规则。美国随之向GATT建议拟定关于技术性贸易壁垒的协议。我国虽然遭遇技术性贸易壁垒的案例早已有之,但…     

Optimal Environmental Tax and Level of Privatization in an International Duopoly

This paper explores the optimal environmental tax and level of privatization in an international duopolistic market. We show that when the government is able to control the environmental tax and the extent of privatization, the optimal environmental tax is lower than the standard Pigouvian level. We also show that the optimal level of privatization of state-owned enterprises is partial privatization. Further, the optimal level of privatization is inversely dependent on the cleanup cost of past environmental contamination.     

Stock market interdependence between Australia and its trading partners: does trade intensity matter?

We investigate the extent and manner of stock market interdependence between Australia and its trading partners and examine whether this is affected by trade intensity. Based on trade intensity, we classify Australia’s trading partners into major, medium and minor partners. We hypothesize that markets with greater (lower) trade intensity will be more (less) interdependent with Australia. We perform correlation (unconditional and conditional) analyses between Australia and its trading partners. Our results indicate that most of the markets that are highly correlated with Australia are its major trading partners. We conduct panel regression analysis to investigate whether trade intensity has any impact on the stock market correlations between Australia and its trading partners. The results show that trade intensity significantly and positively affect the correlations of Australia with its major trading partners. Thus, the results confirm our hypothesis that trade intensity drives stock market interdependence between Australia and its trading partners.     

On the estimation and forecasting of international migration: how relevant is heterogeneity across countries?

This paper performs a comparative analysis of estimation as well as of out-of-sample forecasting results of more than 20 estimators common in the panel data literature using the data on migration to Germany from 18 source countries in the period 1967–2001. Our results suggest that the choice of an estimation procedure has a substantial impact on the parameter estimates of the migration function. Out-of-sample forecasting results indicate the following: (1) the standard fixed effects estimators clearly outperforms the pooled OLS estimator, (2) both the fixed effects estimators and the hierarchical Bayes estimator exhibit the superior forecast performance, (3) the fixed effects estimators outperform GMM and other instrumental variables estimators, (4) forecasting performance of heterogenous estimators is mediocre in our data set.
