In Search of Optimised Regional Trade Agreements and Applications to East Asia

We quantitatively analyse the trade effects of enhanced trade facilitation with extended gravity equations. Our findings confirm that RTAs comprised of countries equipped with better trade facilitation are more likely to be trade‐creating, less likely to be trade‐diverting, and are thus more likely to lead the world economy toward global free trade. We also find that (i) the traditional gains from shallow integration through eliminating tariff barriers will be greater for South‐South RTAs in East Asia such as an ASEAN‐China RTA, provided that the tariff‐reducing schedule is strictly fulfilled, (ii) the gains from deeper integration through enhancing trade facilitation will be greater for North‐North RTAs in East Asia such as a Japan‐Korea RTA, and (iii) the gains from a combined trade liberalisation strategy through tariff reductions and enhanced trade facilitation will be greater for North‐South RTAs in East Asia such as a China‐Korea and an ASEAN+3 RTA.     

Proliferating Regional Trade Arrangements: Why and Whither?

This paper investigates why regional trade arrangements (RTAs) are proliferating extensively and how the effects of multiple RTAs, by interacting with each other, evolve over time. Our empirical analysis, based on an extended gravity model utilising a large panel dataset of 175 countries from 1948 to 1999, shows that RTAs on average increase global trade by raising intra‐bloc trade without damaging extra‐bloc trade. The net trade effects, however, heavily depend on the types of RTA strategic evolution over time, which we categorise as ‘expansionary’ RTAs, ‘duplicate’ RTAs or ‘overlapping’ RTAs. We find that countries excluded from an RTA can benefit more from duplicating a separate RTA than from joining an existing RTA. This result explains why the number of bilateral trade blocs, rather than the membership size of existing RTAs, is currently exploding. We also find that the net trade‐creating effects of RTAs are substantially lower for countries participating in overlapping RTAs. This result suggests that it is less likely that the currently proliferating RTAs will completely merge and lead the world economy to global free trade. Our empirical results are robust to controlling for the characteristics of countries that may influence the impact of RTAs.     

RTAs' Proliferation and Trade‐diversion Effects: Evidence of the ‘Spaghetti Bowl’ Phenomenon

This paper investigates the trade‐diversion effects of regional trade agreements (RTAs), so‐called spaghetti bowl phenomenon (SBP), in multilateral trade. The SBP is due to the proliferation of RTAs. Thus, I investigate the relationship between the number of RTAs concluded by a country and the additional trade value attributed to a RTA. Using bilateral trade data in a sample of 119 countries, from 1995 to 2012, my main finding reveals a negative trade effect between them, confirming the existence of SBP in multilateral trade. However, results could not conclude the evidence of a negative effect of overlapping RTAs, involving the existence of SBP, within North–North, North–South or South–South trade. But, the additional trade value attributed to a RTA concluded with EU countries or US seems to confirm significantly a trade‐diversion effect because of the number of RTAs signed by these countries.     

The trade structure effects of endogenous regional trade agreements

This paper formulates an empirical model to estimate the impact of endogenous new regional trade agreement (RTA) membership on trade structure. The likelihood of new RTA membership is influenced by economic fundamentals such as country size, factor endowments, and trade and investment costs. In a sample of country-pairs covering mainly the OECD economies we find a particularly strong effect of endogenous RTAs on intra-industry trade in a difference-in-difference analysis based on matching techniques. The associated trade volume effects are similar to the ones found in previous research on the effects of endogenous RTAs. Overall, this indicates that RTA membership might reduce inter-industry trade not only in relative but also in absolute terms and that the trade volume effect is due to the associated growth in trade within industries.

Formation of interdependent regional trade agreements and production networks

Production networks (PNs) can be defined as a determinant of trade partnership. Deepening PNs may generate positive welfare effects and lead to a proliferation in the formation of interdependent regional trade agreements (RTAs). This paper theoretically develops the link between PNs and the formation of RTAs and empirically investigates the link by applying a qualitative choice model estimation methodology (probit) with panel data that covers bilateral country‐pairs among 147 countries between 2000 and 2010. We find that the RTA formation has been strongly driven by deepening PNs between members as well as with third countries. We also find that production network‐driven RTA interdependence is member specific.     

Do deeper regional trade agreements enhance international technology spillovers?

We examine whether regional trade agreements (RTAs) enhance international technology spillovers using a panel of patent citation data for 114 countries/regions for the period 1991–2007. We use patent citations as a proxy for technology spillovers. The focus of this study is on whether the depth of regional integration matters for technology spillovers among member countries/regions of RTAs. The depth of integration is measured by the extent to which an RTA includes legal obligations outside the current mandate of the World Trade Organization. We find that the depth of integration actually influences technology spillovers and that a deeper integration in a broad sense has a greater impact on technology spillovers than do technology‐related provisions.     

Revisiting the effect of regional integration on African trade: evidence from meta-analysis and gravity model

Two main shortcomings flaw the estimation of gravity model in previous studies that examined the trade-creating effects of African Regional Trade Agreements (RTAs). First, these studies fail to account for the multilateral resistance term. This omission makes the estimates from standard gravity model bias and inconsistent. Second, there is a significant proportion of zero trade flows, however, these studies also fail to account for them properly. They use either the Tobit model or replace zero flows with arbitrary small values. Apart from these problems, they also exhibit considerable heterogeneity in the RTA effects on trade. In this paper, a meta-analysis of previous empirical studies is conducted to derive a combined effect size and also to explain the heterogeneity. In addition, I use the gravity model to compare the trade-creating effect of the main African RTAs. Using the gravity model, I compare the estimation methods of previous studies to the Poisson pseudo-maximum-likelihood estimator that tackles the zero flows. From the meta-analysis, I find a general positive effect of African RTAs of about 27%–32%. A comparative assessment of the RTAs using gravity model shows a striking heterogeneity.     

Regional Trade Agreements and the Pattern of Trade: A Networks Approach

This paper uses a complex network approach for the analysis trade effects from regional trade agreements on world trade flows. We use bilateral trade data to compute the network community structure for every year between 1970 and 2000. We compare this to null community structures that emerge from various models based on regional and geographical classifications, the implementation of RTA's and gravity models of trade. Our results show that RTA formation appears to have a cyclical pattern on the world trade network community structure. We document periods where bilateral trade flows and the structure of the world trade network are consistent with those predicted by formation of RTAs. These cycles occur in 1980–86 and 1990–96. At the same time, we document periods in which the pattern in the world trade network is not explained by RTA formation. Two periods, 1986–90 and 1997–2000, show a pattern of bilateral trade flows that moves away from the prediction that results from assuming RTA formation as the driving force in the determination of the world trade network structure. Factors contributing to the latter parts of the cycle during our sample period include formation of regional trade networks in East Asia that account for a significant portion of world trade but are not formalised by RTAs in force.     

Trade Creation and Diversion Effects of Regional Trade Agreements: A Product‐level Analysis

This paper examines the impacts of regional trade agreements (RTAs) on trade flows at product level, with a particular focus on trade creation and diversion. Based on estimation of the gravity equation, dealing with the zero trade flows and endogeneity bias problems, we analyse the impacts of various types of RTAs involving 67 countries for 20 products during the 1980–2006 period. We find that RTAs among developing countries tend to cause trade diversion compared with RTAs among developed countries. Taking the higher external tariff rates of developing countries compared with developed countries into consideration, our results suggest trade diversion is likely to be caused by remaining high tariffs on imports from non‐members. In addition, we find the trade creation effect for many products in the cases of Customs Unions and plurilateral RTAs. These results imply that trade creation would be caused by various factors besides the reduction in tariff rates. Based on these results, we draw a policy implication that external tariff rate reduction is an important factor in avoiding trade diversion in the formation of RTAs, in particular for RTAs among developing countries, while a large number of members and the common external tariff appear to be important for generating the trade creation effect.

Do Trade Agreements Increase Food Trade?

In addition to multilateral trade agreements under the World Trade Organization (WTO), the world has seen a remarkable proliferation of regional trade agreements (RTAs) in the last two decades. This study investigates whether these multilateral and regional trade institutions increase food trade and bring the world into a freer flow of food. The gravity model of international trade is used for the empirical analysis. The model is developed in a large panel data setting and attempted to address some potential problems in the estimations including multilateral trade resistances, zero trade values and endogeneity. The results suggest that both the WTO and RTAs have delivered significant positive effects on trade among the participant countries, but not food. Only RTAs are found to have increased food trade among the participant countries. However, although on average the WTO is found to have negative implications on food trade, it facilitates the developing countries more than the developed countries.     

The potential of African trade integration – Panel data evidence for the COMESA-EAC-SADC Tripartite

ABSTRACT

The COMESA-EAC-SADC Tripartite FTA, formed in 2011, is supposed to be a milestone towards Africa's continental trade integration. This study analyzes the impact of regional integration among the Tripartite countries on their bilateral imports before that date to evaluate the latest integration efforts. We estimate an extended gravity model on a large panel of 51 African countries using yearly observations from 1995 to 2010. We proxy existing formal trade barriers by sample average tariff data on imports from the world as well as indicator variables for the membership in regional FTAs. We consider different estimation techniques and discuss distinct sets of fixed effects. The PPML regression results indicate that remaining tariffs are significantly negatively correlated with imports throughout the preferred multiplicative models. An FTA status does not show a clear-cut import enhancing effect. In the specifications that control for country-year effects, the EAC coefficient is positively correlated with imports, and the COMESA and SADC FTA membership show a positive relation to imports within some reduced-sample robustness checks.     

全球价值链分工下区域贸易协定能降低服务贸易成本吗

全球价值链分工下服务的作用愈发凸显,服务贸易的新形式丰富了区域贸易协定影响服务贸易成本的渠道。本文从中间投入和最终需求两个维度分析了区域贸易协定对不同类型服务贸易成本的影响效果和机制。结果表明:单纯签订区域贸易协定对服务贸易成本的抑制作用并不显著,提高区域贸易协定的深度将显著降低服务贸易成本。区域贸易协定可以显著降低中间投入服务贸易成本,对最终需求服务贸易成本的抑制效应不显著。区域贸易协定的服务贸易自由化效果存在非对称性,北北型区域贸易协定对服务贸易成本的抑制效应强于南北型。北北型区域贸易协定可以通过减少监管分歧和货物贸易自由化效果外溢两条途径降低服务贸易成本,南北型区域贸易协定则仅可以通过货物贸易自由化的外溢效应来降低服务贸易成本。因此,中国应积极与发达国家开展高质量区域贸易协定谈判,通过提高区域贸易协定深度充分发挥其服务贸易自由化效果。     

对发展中国家的特殊和差别待遇——以WTO有关区域贸易安排的规定为视角

特殊与差别待遇,是世贸组织处理发展中成员方经济发展问题时必须遵循的一项基本原则。但是,世贸组织有关区域贸易协定的现有规范却缺乏对发展中国家的特殊考虑,这不利于发展中国家参与区域经济合作,促进其经济发展。多哈部长宣言授权成员方在区域贸易协定的谈判中考虑发展问题,但是发达成员和发展中成员在此问题上存在争议,尚未达成共识。发展中国家应当积极参与谈判,争取保留授权条款,同时在24条中引入特殊和差别待遇。作为交换条件,发展中国家可以接受就南南型区域贸易协定向世贸组织进行通知并由其进行审查。     

Is Regionalism an Increasing Feature of the World Economy?

Measuring the importance of regionalism in international trade is desirable but difficult. The number of regional trade agreements (RTAs) reported to the WTO or the proportion of world trade which is between countries in an RTA are frequently cited as evidence that regionalism is growing at an accelerating rate. This paper questions whether RTAs really are as important as the headline numbers suggest, or whether they just occupy an excessively large part of policymakers’ and economic journalists’ time. The main contributions are to analyse the number of RTAs and the share of world trade criteria in order to show why both are meaningless in the current world economy. The paper concludes that, although the extent of regionalism is difficult to measure and the desirability of individual RTAs is difficult to assess, the threat to the multilateral trading system does not appear to be as large as is often reported, because the long‐term dynamics of RTAs lead either to state formation, which is important but rare, or to ineffectiveness, which is the fate of the vast majority of RTAs.     

The High-Value Commodity Export Effects of Standards in Africa

ABSTRACT

The stringency in standards usage, especially in developed markets, has trade effects, particularly for Africa. Thus, this study investigated the export effects of the EU standards for Africa in a two-step, Helpman et al. (2008) model for two high-value commodities. In all, 52 African countries were considered from 1995 to 2012. This study finds that fish standards are trade enhancing at the extensive margins, but not at the intensive margins. However, vegetable standards are trade inhibiting at both the extensive and intensive margins. Thus, these findings suggest that the impacts of standards on exports are commodity-specific.     

Regional Integration and Trade: Controlling for Varying Degrees of Heterogeneity in the Gravity Model

The proliferation of regional trade agreements (RTAs) in the 1990s prompted a renewal of interest in studying the effect of regional integration on trade. Using a panel dataset of bilateral export flows from 12 EU countries to 20 OECD trading partners over the period 1992–2003, the trade effect of European regional integration, denoted by an EU dummy, is examined across a number of fixed effects (FE) specifications, each of which has been claimed as the correct econometric specification of the gravity model. Typically parsimonious in (time‐varying) economic variables and abundant in fixed effects, the FE specifications allow for varying degrees of heterogeneity in the gravity model. Two gravity models are estimated: a gravity model of traditional trade determinants and a gravity model of new trade theory (NTT) determinants. Both gravity models provide reasonable coefficient estimates, although they vary somewhat across the FE specifications for the traditional gravity model. Both gravity models are congruent in suggesting that the coefficient of the EU dummy declines in magnitude and becomes insignificant as an increasing degree of heterogeneity is admitted into the model. This suggests the fundamental importance of the econometric specification when evaluating trade policy effects within a gravity framework.     

中非农产品产业内贸易及影响因素——基于2000～2010年中国与非洲25国面板数据的实证研究

文章运用G-L指数和GHM分类方法,通过对2000～2010年中国与非洲25国农产品产业内贸易指数的测算及影响因素的实证研究,结果表明:从各国来看,中国与非洲12国农产品产业内贸易趋势明显;而从农产品各章目来看,中非农产品贸易则以产业间贸易为主;同时,GHM分类方法显示中非农产品贸易呈现出明显的垂直型产业内贸易特征。此外,回归模型表明市场结构与中非农产品产业内贸易呈负相关关系,而人均收入差异、国家贸易政策则在一定程度上促进了中非农产品产业内贸易的发展。     

Trade structure and economic growth

Abstract

How do the number of trade partners and the concentration of trade among partners affect the economic growth of a country? We refer to these characteristics as the structure of trade, and explore this question empirically in this study. We find that the structure of trade, independently of the level of trade itself, has an important effect on the rate of economic growth. The results of the study suggest that the number of trading partners is positively correlated with growth across all countries, and this effect is more pronounced for rich countries. Trade concentration is positively correlated with growth for all countries, and the effect is concentrated in poor countries. Previous work has overlooked these characteristics of trade, although we find them to be quite relevant and that they could lead to new ways of understanding the trade – growth relationship.
