North, South and distance in the gravity model

It is generally assumed that distance in the gravity model strictly reflects frictions impeding bilateral trade. However, distances North-South could also reflect differences in factor endowment that provide opportunities for profitable trade. This paper investigates the hypothesis that if we control for distance in the ordinary sense, differences North-South promote international trade. The hypothesis receives ample support. Moreover, the significance of differences North-South survives a battery of robustness tests, concerning period, distinctions between differences in latitude North-North, North-South and South-South, and controls for other measures of differences in factor endowment, such as differences in per capita output and differences in average temperature, rainfall, and seasonal range in temperature. The impact of differences North-South on bilateral trade has also been falling. This decline, in turn, might be partly responsible for the weakening of the influence of distance that has been occurring since World War II. This last hypothesis receives confirmation as well. Finally, the paper examines the impact of internal distance and remoteness on trade. Since both variables are country-specific, this is done by studying their impact on the country fixed effects themselves in the earlier estimates. Internal distance turns out to have a far greater impact than remoteness—by an order of 10.     

内地与香港双边贸易流量与潜力研究——基于贸易引力模型的实证分析

内地各省市（自治区）的GDP和人均GDP、香港人均GDP、绝对距离以及泛珠三角区域合作组织等解释变量,是影响双边贸易流量的主要因素;各因素的影响程度互有不同,内地各省市（自治区）对香港的出口贸易潜力也存在一定差异。因此,内地与香港应采取针对性的措施,进一步加强经贸交流和合作,充分发挥各自的区位优势和竞争优势,实现两地经济的共同繁荣。     

Linder Revisited: Trade and Development in the Spanish Economy

The literature has tended to treat Linder’s hypothesis with excessive simplicity given the absence of any formalization for this intuitive theory on trade potential in manufacturers, closely related to the intra‐industry trade paradigm. Against this background, in this paper we first propose a complete empirical model of bilateral trade containing all the determinants suggested by Linder, with special emphasis being placed on non‐homothetic preferences, national income distribution, international economic convergence and geographic distance. We then test the model in an appropriate case, namely that of Spain during the period of its economic transition running from approximately 1959 to 1986. This period was characterized by increasing openness and structural change, as well as by convergence until that country’s integration into the then European Economic Community. The results confirm the importance of the characteristics of internal demand, essentially of income distribution and non‐homothetic preferences. We find that trade horizons delimited by bilateral proximity in development and geographical distance, together with multilateral convergence in economic development are the main indicators for selecting trade partners as markets and suppliers, thereby reinforcing the idea that foreign markets can be considered as an extension of the national market.     

Revisiting the role of migrant social networks as determinants of international migration flows

This note revisits the role of migrant social networks (MSNs) as determinants of bilateral migration flows. We do so using two alternative databases, covering about 190 world countries for the period 1960–2000. In line with previous estimates, we consistently find a significant, positive, impact of MSNs at destination. We also find that such an impact decreases very slowly as the year when MSNs are observed is farther back in the past. We also find that geographical distance is becoming less and less important over time but significantly explains the absence of a migration corridor only when MSNs at destination have very small sizes.     

双边政治关系、制度质量与中国对外直接投资*

本文利用中国与其他国家在联合国大会决议的投票行为作为双边政治关系的代理变量,以中国对89个国家2003—2015年对外直接投资数据为样本,分析了双边政治关系对中国对外直接投资的影响。研究表明：整体而言,中国的对外直接投资会受到双边政治关系的显著影响,政治关系的亲密有利于中国对外直接投资的增加。东道国制度质量可以降低中国对外直接投资对双边政治关系的敏感度,且制度质量的调节只能在中国对比自己制度质量高的国家投资时发挥作用。以2008年为分界点,后危机时代双边政治关系对投资的影响更加显著,双边政治关系的经济效应也会显著地受到东道国制度质量的调节。此外,中国改善与“一带一路”沿线国家的政治关系,可以促进中国的对外直接投资。     

How close is Asia already to being a trade bloc?

FTA bilateral and regional negotiations in Asia have developed quickly in the past decade moving Asia ever closer to an economic union. This paper uses a fifteen-country global general equilibrium model with trade costs to numerically calculate Debreu distance measures between the present situation and potential full Asia integration in the form of a trade bloc. Our results reveal that these large Asia economies can be close to full integration if they act timely in agreements through negotiation. All Asia countries will gain from Asia trade bloc arrangements except when the Asia FTA can only eliminate tariffs. These countries’ gain will increase as bilateral non-tariff elimination deepens. Larger countries will gain more than small countries. Asia FTA, Asia Union and RCEP will benefit member countries more than ASEAN+3. Global free trade will benefit all countries the most.     

Does time difference between countries reduce bilateral trade? An application of the correlated random effects method using panel data

This article implements the correlated random effects (CRE) panel data technique in a gravity framework to analyse the effect of time difference between countries on bilateral trade. One major advantage of the CRE approach over the fixed-effects approach is that it is able to estimate the effect of variables that remain unchanged within panel clusters (e.g. time difference between countries), while these variables get dropped from regressions that use fixed-effects methods. Regression results based on the CRE Poisson pseudo-maximum likelihood estimator indicate statistically significant negative effect of time difference between countries on bilateral trade. An additional hour of time difference between countries is found to reduce bilateral merchandise exports by approximately 8%, even after controlling for the effect of distance in the regressions.     

FDI from the south: The role of institutional distance and natural resources

Using a novel dataset of bilateral FDI flows, we analyze location choices of investors from emerging economies, with an emphasis on institutions and natural resources. We show that FDI from the South has a more regional aspect than investment from the North. Institutional distance has an asymmetric effect on FDI depending on whether investors choose countries with better or worse institutions. In the latter case, large institutional distance discourages FDI inflows, but this deterring effect is diminished for destination countries with substantial resources. We also find a complementary relationship between capital flows from the North and the South in developing recipient countries, which we attribute to different FDI patterns of these investors.     

遗传距离对跨国收入差距的影响研究：理论和中国的实证分析

遗传距离是指两个民族的人追溯到他们最近的共同祖先所过去的时间。本文在Spolaore and Wacziarg(2009)的理论基础上,将遗传距离对跨国收入差距的影响机制内生化。本文采用民族加权法测算了中国与全球107个国家间的遗传距离,对2001—2010年跨国数据的面板IV估计结果表明:遗传距离通过人力资本和国际贸易的渠道对跨国收入差距产生显著的正向影响。遗传距离对跨国收入差距的作用机制在中国与44个遗传距离较远的国家间更为显著。实证结果具有稳健性。     

Bilateral portfolio dynamics during the global financial crisis

There has been considerable bilateral variation in the pattern of portfolio capital flows during the global financial crisis: for a given destination, investors from different countries adjusted their holdings to different degrees. We show that the size of the initial bilateral holding, geographical distance, common language, the level of trade and common institutional linkages help to explain the pattern of adjustment. These bilateral factors are more important for equities than for bonds and for investors from developing countries than for investors from advanced countries.     

Exchange Rate Dynamics in a Multilateral Target Zone

This paper presents a model of exchange rate behaviour in a multilateral target zone. The model produces new economic insights beyond the well-known bilateral model of Krugman (1991), which is obtained as a special case. The paper also introduces a new class of stochastic processes in economics, namely multidimensional reflected diffusion processes.
Two main features characterize the economics of exchange rates in a multilateral target zone. (i) The restrictions on interventions imposed by cross-currency constraints: when one country changes its money supply, say because its exchange rate with a second country has hit its band, all exchange rates involving the currency of that particular country will be affected, regardless of their position within their respective bands. (ii) Cooperation in sharing the intervention burden: in general, the exchange rate between any two countries will depend on the fundamentals of third countries in a multilateral target zone. This is because if the monetary authorities intervene together, a shock in the fundamentals of any country will induce a revision of the expectation of future interventions of other countries.
The model reverts the counterfactual predictions of the bilateral model that the exchange rate steady-state density should be U-shaped and that its volatility should be a decreasing function of the distance of the exchange rate to the limits of its band. Thus, accounting for the multilateral feature of real-world target zones allows us to reconcile target zone models with the most salient empirical features of exchange rate behaviour.     

Transfers in the gravity equation

This study integrates development aid into a theoretically founded structural gravity model that considers primary and secondary effects of aid as an income transfer and as a bilateral trade cost determinant. We identify the parameters of our model using a two‐stage approach that includes a state‐of‐the‐art Poisson pseudo‐maximum likelihood gravity estimation for a sample of 132 countries over the period 1995 to 2012. The main findings indicate that bilateral aid only increases bilateral trade for countries that do not have a common language, a past colonial relationship or an RTA. On average, 1 USD of additional foreign aid from all donors increases recipients’ net imports by around 0.36 USD. Our comparative statics indicate that donors experience a reduction in real consumption due to aid and recipients an increase. We also analyze the effect on third countries. The modelling framework also applies to the study of other transfers such as remittances.     

制度距离、相邻效应与双边贸易--基于“一带一路”国家空间面板模型的实证分析

制度在双边贸易中具有举足轻重的作用。文章首次将相邻效应引入传统的制度与贸易关系的分析框架,运用空间面板模型深入考察了制度距离、相邻效应对中国与“一带一路”国家双边贸易的影响。结果表明,中国与“一带一路”沿线国家之间在文化、法律、宏观经济制度以及微观经济制度方面的差异显著抑制了双边进出口贸易的发展,并且这种抑制作用在长期更为显著。进一步引入相邻效应的分析表明,中国与“一带一路”沿线国家之间的双边贸易受到中国与沿线国家邻国之间贸易的制约,即相邻效应表现为竞争关系,并且无论是针对进口贸易还是出口贸易而言,中国与沿线国家之间的制度距离均强化了相邻效应的“竞争”作用,但上述作用在不同地区具有显著差异。因此,在推进“一带一路”战略时,中国需要考虑制定相关的配套政策来平衡中国与“一带一路”国家,特别是与这些两两相邻国家之间的双边贸易利益,以促进中国与各国双边贸易关系的良性发展。     

中国与G-7的双边服务贸易成本的测度与决定因素——基于改进引力模型的应用

对中国双边服务贸易成本的测度和对其决定因素的探寻可以更好地为服务贸易流动提供解释,对中国服务贸易开放有重要的政策启示。笔者基于改进的引力模型,测度了1999年～2007年间中国与G-7的双边服务贸易成本,并利用面板数据对其进行分解,以此寻求影响中国对外服务贸易成本的因素。结果表明:中国与G-7的双边服务贸易成本总体呈下降趋势,并且在加入WTO后有加速的迹象;空间距离与服务贸易壁垒是双边服务贸易成本存在的主因,与贸易国的人均收入之差及共同的海陆边界有助于降低双边服务贸易成本,共同的贸易集团对于两国服务贸易成本的影响并不明显。     

Je t'aime, moi non plus: Bilateral opinions and international trade

This paper studies the relationship between bilateral trade patterns and opinions. It uses the Eurobarometer public opinion surveys published by the European Commission, which provide data on the share of the population in each EU15 member country in favour of each CEEC joining the EU. Our results first suggest that bilateral opinions have a statistically robust and relatively large effect on imports, even when standard and new covariates capturing proximity between countries are controlled for. We interpret this effect as reflecting a positive impact of “bilateral affinity” on trade patterns. We also show that it is possible to go some way towards explaining the variance in bilateral opinions among our sample. Last we provide some preliminary attempt to determine causality between bilateral opinions and imports.     

Foreign direct investment: the role of institutional and cultural determinants

Using panel data for 29 source and 65 host countries in the period 1995–2009, we examine the determinants of bilateral FDI stocks, focusing on institutional and cultural factors. The results reveal that institutional and cultural distance is important and that FDI has a predominantly regional aspect. FDI to developing countries is positively affected by better institutions in the host country, while foreign investors prefer to invest in developed countries that are more corrupt and politically unstable compared to home. The results indicate that foreign investors prefer to invest in countries with less diverse societies than their own.     

双边自由贸易协定深度异质性及区内全球价值链效应*——基于GVC修正引力模型实证研究

双边自由贸易协定深度嬗变，全球价值链引致贸易形成机制和形式变化，使得自由贸易区理论基础、影响机制和功能效应更替。本文基于对双边自由贸易协定深度演化以及相较于其他区域贸易协定的深度异质性研究，将公司产权理论纳入自由贸易区理论框架，形成双边自由贸易区内全球价值链效应的多维理论机制，并且运用适应全球价值链发展的修正引力模型和世界银行的贸易协定内容数据库对理论机制假设结论进行实证检验。研究发现：双边自由贸易协定总深度对区内成员国之间的全球价值链关联产生正向影响，相较于贸易相关条款深度而言，投资相关条款深度影响更大。此外，自由贸易区对象国差异性也会影响双边自由贸易区全球价值链效应的发挥。根据对象国不同选择差异化的自由贸易区深度在双边自由贸易区构建中重要性凸显。本文将为全球价值链背景下中国构建高标准自由贸易区网络的对象国选择、自由贸易区模式选择等提供政策参考。

Does Trade Integration Contribute to Peace?

We investigate the effect of trade integration on interstate military conflict. Our empirical analysis, based on a large panel data set of 243,225 country‐pair observations from 1950 to 2000, confirms that an increase in bilateral trade interdependence significantly promotes peace. It also suggests that the peace‐promotion effect of bilateral trade integration is significantly higher for contiguous countries that are likely to experience more conflict. More importantly, we find that not only bilateral trade but global trade openness also significantly promotes peace. It shows, however, that an increase in global trade openness reduces the probability of interstate conflict more for countries far apart from each other than it does for countries sharing borders. The main finding of the peace‐promotion effect of bilateral and global trade integration holds robust when controlling for the simultaneous determination of trade and peace.     

Distance and trade: Disentangling unfamiliarity effects and transport cost effects

This paper provides evidence supporting Grossman's (Comments on Alan V. Deardorff, Determinants of bilateral trade: Does gravity work in a neoclassical world?. In: Jeffrey A. Frankel (Ed.), The regionalization of the world economy. Chicago: University of Chicago for NBER; 1996) claim that not only transport costs but also unfamiliarity can explain the negative correlation between geographic distances and bilateral trade volumes. A gravity model that controls for as many natural causes of trade as possible reveals that countries high in uncertainty-aversion (based on Hofstede's survey) export disproportionately less to distant countries (with which they are presumably less familiar). More important, this result is mainly driven by differentiated products, not by products with international organized exchanges or with reference prices. For transport costs alone to explain such a trade pattern, one would have to assume that distance-related ad valorem transport costs are higher when a trade route originates from a high uncertainty-aversion country, which is unlikely. This trade pattern is easy to explain, however, if one accepts that geographic distance is a proxy for unfamiliarity and that exporters in high uncertainty-aversion countries are more sensitive to informational ambiguity. A further result is that high uncertainty-aversion countries trade less and thus grow poorer in the long run, which suggests that cultural factors are as important as geographic ones in determining trade openness and prosperity.
