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.     

Endogenous trade bloc formation in an asymmetric world

This paper investigates how variations in endowments and the structure of preferences impact on the coalition formation decisions of asymmetric countries. There exist relatively few general results on the relationship between country characteristics and trade bloc formation. Here, new light is shed on this issue by systematically simulating bloc formation and by explicitly analysing the blocking behaviour of coalitions. A general equilibrium model of world trade is implemented with equilibrium coalition formation being modelled using the equilibrium concept of the core. It is found that global free trade is observed when all countries are similar. Customs unions tend to form between countries with ‘adjacent’ consumer preferences or with ‘adjacent’ endowments of their export commodity. Finally, in contrast to the existing literature but consistent with observed behaviour, it is found that free trade areas often Pareto dominate customs unions, provided consumer preferences differ sufficiently.     

Regional Blocs and Foreign Direct Investment

The paper examines the impact of the emergence of regional blocs on the patterns of interbloc and intrabloc trade when firms have the option to engage in foreign direct investment (FDI). For exogenously given external tariffs, when firms have the option to engage in FDI, all interbloc trade may cease—complete trade diversion that is replaced by interbloc FDI investment creation. In such an event the volume of world trade declines but this is more than offset by the increase in world output due to direct investment. The paper also investigates the optimal tariff that a trading bloc levies on imports from nonmember countries. The tariffs are restricted by the option to engage in two‐way direct investment; hence, the regional blocs are hampered from mutually harming one another through an escalation in the tariff war. Finally, the formation of two regional blocs enhances the welfare of all countries.     

Capital mobility,openness, and saving-investment relationship in Asia

The main objective of this paper is to investigate the relationship between openness to trade and saving-investment behaviour in Asia during the period 1990–2006. We use this relationship to examine whether those Asian countries that are more open to trade and enjoy less trade barriers have also higher degree of capital mobility. Cluster analysis is used to classify the countries into different groups according to the share of trade in their gross domestic products and their average tariff rates. The goal is to place the countries that are similar to each other in terms of their trade policy in one group. We apply the Generalized Least Square (GLS) technique to a set of balanced panel error correction models to estimate the short- and long-run relationship between saving and investment. The estimation results indicate that there exist long-run equilibrium relationships between domestic saving and investment in all groups regardless of their degree of trade openness. Moreover, contrary to Amirkhalkhali and Dar (2007) for the case of OECD, we find out that more openness in terms of trade policy is associated with higher degree of capital mobility for the case of Asian countries. One policy implication of this result for the Asian economies is that trade openness can be used as a strategy to attract capital from abroad. Our findings also confirm the prediction of new open economy macroeconomic models regarding the short- and long-run behaviour of current account.     

Trade Blocs and Trade Wars during the Interwar Period

What precisely were the causes and consequences of the trade wars in the 1930s? Were there perhaps deeper forces at work in reorienting global trade prior to the outbreak of World War II? And what lessons may this particular historical episode provide for the present day? To answer these questions, we distinguish between long‐run secular trends in the period from 1920 to 1939 related to the formation of trade blocs and short‐run disruptions associated with the trade wars of the 1930s. We argue that the trade wars mainly served to intensify pre‐existing efforts toward the formation of trade blocs which dated from at least 1920. More speculatively, we argue that the trade wars of the present day may serve a similar purpose as those in the 1930s, that is, the intensification of China‐ and US‐centric trade blocs.     

Currency crisis transmission through international trade

The Eurozone recent crisis has shown how balance of payments problems in less developed European Monetary Union (EMU) member countries can affect EMU trading partners, spreading the crisis to a larger group of countries. This paper introduces a three-country dynamic general equilibrium model to analyze whether and how terms of trade effects can generate a spillover effect or a currency crisis transmission between countries. Specifically, using a two period model, it incorporates world market clearing conditions for tradables into a new theoretic model, analyzes net capital flow movements between countries, and establishes cross-border macroeconomic linkages. This paper shows how a currency crisis can transmit through the real (trade) sector channel of the economy.     

Trade and Relative Wage in a Global Economy

The effects of trade among similar countries and that among dissimilar countries on the relative wage are examined. Product quality is a choice variable by firms. Quantity production is assumed to satisfy constant costs, while quality production is more skilled-labor intensive than quantity production and obeys increasing costs. Compared to autarky, free trade, by fostering more competition, leads to quality improvement, which in turn tends to increase the relative wage. Trade among similar countries increases the relative wage in all trading countries, while trade among dissimilar countries, in a two-country model, increases it in one country but may increase or lower it in the other.     

GRADUAL TRADE LIBERALIZATION WITH SLUGGISH CAPITAL MOVEMENT

Abstract.  This paper analyses how domestic sluggish capital movement can affect multilateral trade negotiations between countries. In multilateral trade talks, including the current Doha Round of trade talks organized by the World Trade Organization, countries take steps to liberalize even though they seem to be moving towards the ultimate free trade equilibrium. This paper argues that when capital moves sluggishly between sectors in an economy, there are cases in which countries do not want to move to the ultimate free trade equilibrium immediately. Instead, they find it more beneficial if they simultaneously move gradually, with their tariffs lowered step by step.     

Globalization and labor market outcomes: Wage bargaining, search frictions, and firm heterogeneity

We introduce search unemployment into Melitz's trade model. Firms' monopoly power on product markets leads to strategic wage bargaining. Solving for the symmetric equilibrium we show that the selection effect of trade influences labor market outcomes. Trade liberalization lowers unemployment and raises real wages as long as it improves average productivity. We show that this condition is likely to be met by a reduction in variable trade costs or by entry of new trading countries. Calibrating the model shows that the long-run impact of trade openness on the rate of unemployment is negative and quantitatively significant.     

International trade and consumption network externalities

This paper studies the effects of trade liberalization in the presence of consumption network externalities. The framework is applicable to the choice of network products and sheds light on the debate on globalization and culture. In an extended Ricardian model of international trade the paper shows that: (i) trade is not Pareto inferior to autarky if the free trade equilibrium is unique; (ii) trade is not Pareto superior to autarky if both countries are diverse (network competition) under free trade, but can be if each country is homogenous (network monopoly); (iii) and when multiple free trade equilibria exist everybody in a country can lose from free trade if that country is homogenous under autarky. Consumers of imported network goods tend to gain, while consumers of exported network goods tend to lose from trade liberalization.     

International Integration and Growth: A Further Investigation on Developing Countries

The paper examines empirically the linkages between international integration and economic growth in a panel of 47 developing countries and 18 trade blocs over the period 1970–1989. Specifically, it attempts to identify through which channel(s) – notably, specialization according to comparative advantage and increased efficiency, exploitation of increasing returns from larger market, and technology spillovers through investment and trade–trade blocs can affect the economic growth of their member countries. The results suggest that (1) intra-bloc trade does not affect growth significantly; (2) income diversion among member countries contributes positively and significantly to growth; and (3) the size of the trade bloc does matter in the sense that the bigger is not always the better for the welfare of the member countries.     

Book Review

This paper analyses determinants of intra-industry trade in food processing for a 30-country sample over the period 1964–85. Previous studies have tested the hypothesis that imperfect competition is a major determinant of intra-industry trade (IIT) in the durable goods manufacturing sectors. This study is distinguised from the earlier studies of IIT by; the examination of the processed food sector (SIC=20), the use of a panel data set for 22 years and 30 countries available at the four-digit SIC level, the use of purchasing power parity measures of GDP, and the use of a weighted tobit model with fixed effects to account for the censored cross-section time-series nature of the date. The results indicate that ITI in food processing is a positive function of a country's GDP per capita and equality if GDP per capita between countries. In addition, it is also found that such trade is strongly influenced by distance between trading partners, membership in customs unions and free trade blocs, and also exchange rate volatility.     

Hub‐and‐spoke free trade areas: theory and evidence from Israel

Abstract We study how the sequential formation of free trade areas affects trade flows between member countries. In a three‐country, three‐good model of comparative advantage if two countries have an FTA, and both sign a similar agreement with the third, trade between the two decreases. However, if only one of them signs an additional FTA, a hub‐ and‐spoke pattern arises, and trade between the initial members increases. Israel’s experience lends strong support to our model: trade between Israel and the EU, subject to an FTA since 1975, increased by an additional 29% after the introduction of the US‐Israel FTA in 1985.     

Regional versus Multilateral Trade Liberalization,Environmental Taxation,and Welfare

The paper considers trade between identical countries with imperfectly competitive markets, and compares the impacts of regional and multilateral tariff reduction on strategic environmental taxation and welfare. While both forms of trade liberalization increase production and consumption in tariff‐reducing countries, regionalism also reduces production in a non‐participating country and may decrease its consumption. Consequently, regionalism and multilateralism change pollution tax and welfare in the tariff‐reducing countries in similar ways when pollution is local, but in dissimilar ways for global pollution. When pollution is global, regionalism is likely to be preferred to multilateralism for the establishment of free trade among countries.     

TRANSPORTATION INFRASTRUCTURE INVESTMENTS AND TRADE LIBERALIZATION*

This paper examines the gains from cooperative agreements on transportation infrastructure investments when there are terms of trade and technological spillovers between countries. In a two ‐country model, cooperation on investment levels will result in a lower level of transport costs. However, the cooperative equilibrium may have a higher or lower level of infrastructure investment between the partner countries in the case of preferential liberalization. The paper also addresses the desirability of linking trade and infrastructure agreements when investment choices can be used strategically.     

The production and trade of manufactured products in the EEC and EFTA: A comparison

This paper presents an examination and comparison of trade creation and trade diversion in the EEC and EFTA. The methodology is based upon changes in shares of expenditure on apparent consumption of manufactured products between 1960 and 1968 on a disaggregated basis. The results indicate that there was considerable trade creation and only a modest amount of trade diversion for each trade bloc. In fact, there was in the aggregate net external trade created due largely to an expansion in imports from outside of either trade bloc and the United States. Despite their different memberships and tariff experiences, the results for the two trade blocs are remarkably similar.     

International Trade Without Autarkic Equilibria

It is possible that wealthy trading countries nevertheless have no autarkic equilibria. However, if a country has no autarkic equilibrium, the offer curve of that country may consist of disjoint segments, which implies that a worldwide trading equilibrium does not always exist, that international exchanges do not always take place in equilibrium, and therefore that econometric estimates of the structure of open economies must be viewed with scepticism. In the present paper, I provide conditions that are necessary and sufficient for the existence of a worldwide free-trade equilibrium and for the existence of gains from free trade for individual countries.     

Can regional blocs be a stepping stone to global free trade? a political economy analysis

With a new wave of regional blocs, there is a heightened worry that they may impede the process of global free trade. This paper demonstrates, contrary to the pessimistic views, regional blocs may work as a stepping stone to multilateral liberalization. In our model, global free trade is not politically feasible initially, because too many people think that they will lose from the liberalization. Regional blocs as an intermediate step could divide the original opposition force so that a sequence of liberalization now becomes feasible.     

Asymmetric adjustment costs in simple general equilibrium models

This paper demonstrates that the introduction of asymmetric adjustment costs in a simple general equilibrium framework establishes a meaningful link between factor price determination and output determination, breaking the analytically convenient dichotomy of the Heckscher-Ohlin-Samuelson model. The possibility of trade between seemingly similar countries that differ in their adjustment technologies is visited.     

A UNIFIED ANALYSIS OF TRADE GAINS IN THE PRESENCE OF PUBLIC GOODS*

It has long been known that free trade is potentially (after lumpsum compensatory transfers) beneficial for each trading country if the autarkic and post‐compensation free‐trade equilibria are perfectly competitive, with market distortions limited to non‐negative taxes on imports and exports. However these conditions are merely sufficient. It can now be shown that, under alternative sufficient conditions, free trade is potentially beneficial to each trading country even in the context of public goods.
