Do South–South preferential trade agreements undermine the prospects for multilateral free trade?

Due to trade diversion, there have been concerns expressed over the proliferation of preferential trade agreements (PTAs) that include South countries. In this paper, we compare welfare across different geographic configurations of bilateral free trade agreements (FTAs) and customs unions (CUs) and examine their implications for the stability of multilateral free trade. While North–North PTAs do tend to yield higher global welfare than South–South PTAs, a single South–South FTA may make free trade more sustainable than any other single agreement. With pre‐existing North–North agreements and a large enough cost asymmetry between regions, an additional South member or a new South–South agreement always makes free trade harder to sustain.     

Bilateral Trade Agreements and the Feasibility of Multilateral Free Trade

We studied how the pursuit of bilateral free‐trade agreements (FTAs) affects the likelihood of achieving multilateral free trade. We derive and compare the stable Nash equilibria of two games of trade liberalization: in the FTA game, each country can either form an FTA with one of its trading partners or both of them or none of them, whereas in the (restricted) No FTA game, purely bilateral FTAs are not permitted. The major result is that there exist circumstances under which the freedom to pursue (discriminatory) bilateral FTAs is necessary for achieving multilateral free trade.     

Endogenous Free Trade Agreements and Foreign Lobbying

This paper assesses the political viability of free trade agreements (FTAs) in the presence of lobbying by organized foreign interest groups. The assessment is based on a model in which external tariffs and the decision to form an FTA are endogenously determined. The findings demonstrate that, in the presence of an organized lobby group in a prospective partner country, an FTA may initiate an increase in the level of protection against imports from third countries and impede trade with non‐member countries. Further, this study finds that a foreign lobby may encourage the local government to enter a welfare‐reducing trade‐diverting FTA. Finally, this paper shows that an FTA increases the lobbying power of the organized lobby groups of the member countries, which can potentially obstruct the viability of welfare‐improving multilateral trade liberalization.     

Free Trade Agreements and the Prospects for Regional Integration in East Asia

Trade policy in East Asia has switched from non-discriminatory unilateral liberalization, reinforced by General Agreements on Tariffs and Trade/World Trade Organization (GATT/WTO) commitments, to discriminatory free trade agreements (FTA). The paper surveys the FTA activity of the major regional players: China, the ASEAN countries, Japan, and South Korea. It concludes that emerging FTAs are weak and partial. A hub-and-spoke pattern of dirty FTAs will not drive regional economic integration or further integration with the global economy. Rather, it could be a force of regional economic disintegration – especially if the multilateral trading system weakens further. At the same time, FTA activity is distracting attention from the WTO, and, more fundamentally, from unilateral liberalization and domestic structural reforms. Hence, East Asian trade policies need to be rebalanced, with better-quality FTAs and more focus on the WTO. However, more important than the WTO and FTAs is a fresh spurt of unilateral liberalization and structural reform outside trade negotiations.     

Economic Determinants of Free Trade Agreements Revisited: Distinguishing Sources of Interdependence

One of the most notable international economic events since 1990 has been the enormous increase in the number of free trade agreements (FTAs). While Baier and Bergstrand were the first to show empirically the impact of a country‐pair's economic characteristics on the likelihood of the pair having an FTA, the literature has been extended to demonstrate the importance empirically of FTA “interdependence”—the effect of other FTAs on the probability of a pair having an FTA. In the context of the Baier–Bergstrand framework, this paper delves deeper into the sources of interdependence—an “own‐FTA” effect and a “cross‐FTA” effect. The authors argue that the own‐FTA effect (the impact on the net welfare gains of an FTA between two countries owing to either already having other FTAs) likely dwarfs the cross‐FTA effect (the impact on the net welfare gains of an FTA between the pair owing to other FTAs existing in the rest of the world, or ROW). Augmenting a parsimonious logit model with simple “multilateral FTA” and “ROW FTA” terms to differentiate the own and cross effects empirically, it is shown that the marginal impact on the probability of a country‐pair having an agreement of either country having one more FTA with a third country is 50 times that of one more FTA between another pair in ROW. The results suggest that “domino (own‐FTA) effects” have far exceeded “competitive liberalization (cross‐FTA) effects” in the proliferation of FTAs.     

Multilateralism and Hub‐and‐Spoke Bilateralism*

This paper studies sequential negotiations of bilateral free‐trade agreements in an oligopoly model. The expansion of trading blocs through overlapping trade agreements allows the option of hub‐and‐spoke systems and achieves multilateral free trade as the equilibrium path, even if the expansion of trading blocs through the acceptance of new members is not feasible. The results suggest that free‐trade areas (FTAs) tend to expand more than customs unions (CUs). Lobbying by a producer can either promote or undermine the achievement of multilateral free trade through overlapping FTAs.     

Dynamic Free Trade Networks: Some Numerical Results

To help predict whether the proliferation of free trade agreements (FTAs) continues until global free trade is effectively attained, this paper investigates dynamic paths of FTAs, generated by numerical simulations of a model of an FTA network formation game with many countries. The characteristics of the final FTA network naturally depend on how the proposer of an FTA is chosen in each period. The paper finds that if the country that has the largest incentive to form an FTA is chosen as a proposer in each period, the network evolution always leads to a unique final FTA network, which may or may not be the complete network of FTAs. FTA networks often evolve to a partition of the world into a small number of groups of asymmetric size owing to the negative network externality caused by preference erosion.     

FREE TRADE NETWORKS WITH TRANSFERS*

We investigate the network of bilateral free trade agreements (FTAs) in the context of a network formation game with transfers. In a previous paper we showed that without international transfers countries with different industrialization levels cannot sign an FTA, so that the global free trade network, in which every pair of countries signs an FTA, is not in general pairwise‐stable. In this paper we show that, even if the world consists of fairly asymmetric countries, the global free trade network is pairwise‐stable when transfers between FTA signatories are allowed. Moreover, it is a unique pairwise‐stable network unless industrial commodities are highly substitutable.     

Costs of a missing FTA: the case of Turkey and Algeria

Turkey has been deeply integrated with the EU, its largest trading partner, particularly following the Customs Union agreement in 1996. However, the free trade agreements (FTAs) signed by the EU with third party countries may create some unfair competitive pressures, market share and welfare losses for Turkey. This study investigates the impact of the FTA signed by Algeria and the EU in 2005 on Turkey’s trade flows. Covering 181 countries, a difference-in-differences analysis embedded in an extended gravity framework is employed to quantify the trade effects of the EU-Algeria FTA for the period of 1996–2013. Our findings suggest that bilateral trade between Turkey and Algeria is affected adversely due to the FTA. The counterfactual analysis shows that Turkish exports and imports to/from Algeria could have been 12 and 17% higher, respectively, had there been no FTA between the EU and Algeria.

Barriers to Global Free Trade through Bilateral Agreements

This paper examines the formation of bilateral free trade agreements (FTAs) in the context of a dynamic noncooperative bargaining game with a random proposer. We show that global free trade (a grand coalition) does not necessarily occur unless transfer payments among countries are allowed. When transfer payments are possible, bilateral FTAs always achieve global free trade, but the ex‐ante and ex‐post inequalities of social welfare among countries are larger than those when all countries are independent because of the strategic bargaining behavior.     

Does it Matter Who You Sign With? Comparing the Impacts of North–South and South–South Trade Agreements on Bilateral Trade

Free trade agreements (FTAs) lead to a rise in bilateral trade regardless of whether the signatories are developed or developing countries. Furthermore, the percentage increase in bilateral trade is higher for South–South agreements than for North–South agreements. The results are robust across a number of gravity model specifications in which we control for the endogeneity of FTAs (with bilateral fixed effects) and also take account of multilateral resistance in both estimation (with country‐time fixed effects) and comparative statics (analytically). Our analytical model shows that multilateral resistance dampens the impact of FTAs on trade by less in South–South agreements than in North–South agreements, which accentuates the difference implied by our gravity model coefficients, and that this difference becomes larger as the number of signatories rises. For example, allowing for lags and multilateral resistance, a four‐country North–South agreement raises bilateral trade by 53% while the analogous South–South impact is 107%.     

Dynamic formation of preferential trade agreements: The role of flexibility

In practice, free trade agreements (FTAs) vastly outnumber customs unions (CUs). Nevertheless, the literature traditionally views CUs as optimal for members because CU members coordinate external tariffs. I show that a dynamic FTA flexibility benefit can help explain the prevalence of FTAs: individual FTA members have the flexibility to form their own future FTAs whereas CU members must jointly engage in future CU formation. I show how the relative prevalence of FTAs versus CUs depends on the structure of market size asymmetry across countries and use these predictions to shed some light on FTA versus CU formation in Europe and South America.     

The silent success of customs unions

Globally, 81 countries are now part of a customs union (CU), following the rapid proliferation of this type of trade agreement in past decades. Much of this growth has been driven by countries “upgrading” their links from a free trade agreement (FTA) to CU. At the same time, the rapid formation of new FTAs among countries that had no prior agreement in place has largely overshadowed this growth, making CUs the silent success of regional integration. Using the canonical regionalism model, augmented to allow for political bias towards firm interests, we investigate the endogenous choice of trade agreement. We show it is generally politically viable to move from FTA to CU, because such a move is rent‐creating; but for countries without a trade agreement in place, it may be optimal to form an FTA as a stepping stone to reduce the risk of political derailment. Importantly, forming a CU is consistent with member social welfare maximization: as long as trade with the rest of the world does not cease entirely, a CU leads to higher social welfare than either FTA or no agreement. These gains come at the expense of third‐country welfare. If past trends continue, one can expect more FTAs to be upgraded to CU with associated adverse consequences for outsiders.     

Trade policy and productivity

Previous studies on the determinants of productivity emphasized the role of trade and institutions but omitted trade policy due to endogeneity concerns. This paper considers the role of one important element of trade policy: free trade agreements (FTAs). Based on recent work on the determinants of FTAs, we suggest an instrument which is based on the propensity to enter an FTA due to (exogenous) geographical characteristics. We find that differences in institutional quality and trade, due to variations in geography and trade policy, have a sizeable effect on productivity and can explain the huge variation in per capita income across countries.     

Do Customs Union Members Engage in More Bilateral Trade than Free‐Trade Agreement Members?

This paper provides the first empirical analysis directly comparing the effects of customs unions (CUs) and free‐trade agreements (FTAs) on members’ bilateral trade, while addressing the biases arising from log‐linearization of the gravity model and crucial time‐invariant unobservables. Since Fiorentino et al. (2007 ) question the popularity of CUs relative to FTAs, considering the latter to be more practical in the current trading climate, such a comparison seems especially relevant. While Baier and Bergstrand (2007 ) find an FTA to approximately double members’ bilateral trade after 10 years, the results of this paper find CUs to have had a much larger impact than FTAs.     

Are free trade agreements good for the environment? A panel data analysis

This study empirically examines the relationship between free trade agreements (FTAs) and greenhouse gas (GHG) emissions. For this purpose, we use three different FTAs: the Southern Common Market, the North American Free Trade Agreement, and the Australia–United States Free Trade Agreement. These FTAs are between developing, both developing and developed, and only developed countries, respectively. Panel unit root, panel cointegration, and fully modified ordinary least squares estimations are employed to examine the long‐run relationship between GHG emissions and trade liberalization. The results indicate that the environmental effects of FTAs depend on the different agreement types. When FTAs are between only developed or developing countries, overall there is no environmental damage, and these types of FTAs can be beneficial for the environmental quality in the long run. However, when developing and developed countries are in a trade agreement, overall environmental quality decreases due to increased GHG emissions.     

Exempted sectors in free trade agreements

Almost all participants in free trade agreements (FTAs) exclude at least a few products or sectors from complete tariff removal on the exports of their FTA partners. The positive tariffs that remain within an FTA are often the highest tariffs that the countries apply on an MFN basis. It seems plausible that such exclusions may be chosen because the domestic producers of these products are viewed as especially vulnerable to competition from imports from the partner country. In brief, they are especially “sensitive sectors.” We develop this idea theoretically and then test it empirically on data from 37 countries in 240 importer–exporter pairs within FTAs. We find support for the sensitive‐sector hypothesis only in the high‐income countries. We find that low‐income countries, in contrast, exempt sectors where bilateral tariff removal would be more likely trade‐diverting and therefore harmful. Our explanation for this, supported empirically, is not that they are following the advice of trade economists, but rather that they are avoiding loss of tariff revenue and may also perhaps be influenced by the greater bargaining power of richer and/or larger partners in their FTAs.     

Are Preferential Trade Agreements with Non-trade Objectives a Stumbling Block for Multilateral Liberalization?

In many preferential trade agreements (PTAs), countries exchange not only reductions in trade barriers but also cooperation in non-trade issues such as labour and environmental standards, intellectual property, etc. We provide a model of PTAs motivated by cooperation in non-trade issues and analyse its implications for global free trade and welfare. We find that such PTAs increase the cost of multilateral tariff reductions and thus cause a stumbling block to global free trade. This occurs because multilateral tariff reductions decrease the threat that can be used in PTAs and thus the surplus that can be extracted from them. By explicitly modelling the interaction between preferential and multilateral negotiations, we derive a testable prediction and provide novel econometric evidence that supports the model's key prediction. The welfare analysis shows that the current World Trade Organization rules allowing this type of PTAs may be optimal for economically large countries, thus the model can predict the rules we observe. We also analyse alternative rules that constitute a Pareto improvement.     

Unlikely Pivotal States in Competitive Free Trade Agreement Diffusion: The Effect of Japan's Trans-Pacific Partnership Participation on Asia-Pacific Regional Integration

How can a state with dysfunctional trade politics spur the negotiation of major free trade agreements (FTAs)? Using the case of Japan's participation in the trans-Pacific Partnership (TPP), we develop an analytical framework on FTA diffusion that takes into account multidimensional (economic, legal and political) competitive pressures, and the ability of states to act as pivots in triggering FTA cascades. We disaggregate the makeup of a pivotal state into two main components – capability and credibility – and underscore Japan's significant latent capabilities, but also its serious credibility shortcomings. The TPP's boost to Japan's credibility raised the possibility of significant economic, legal and political externalities for specific countries which responded by accelerating FTA initiatives that had long stalled: the trilateral China–Japan–Korea FTA, a 16-state East Asian FTA and the Japan–European Union trade negotiations. This study extends the theoretical frontier in policy diffusion studies by clarifying the combination of factors that allows some states, but not others, to activate the externalities behind the dissemination of defensive FTAs.
