Reforming the GATT: The use of trade measures for balance-of-payments purposes

The GATT rules which govern international trade are to be reformed during the current Multilateral Trade Negotiations. It is widely agreed that among the rules most in need of change are those relating to the use of trade policy measures, such as import quotas and surchages, for balance-of-payments purposes. This article reviews the role of such measures under international monetary regimes based on both fixed and flexible exchange rates, and concludes that they should no longer be authorized by the GATT. If they do remain part of the system, a number of major changes are needed in both the substantive and procedural rules which govern their use.     

The dynamic effects of a currency union on trade

The response of trade to a monetary union is a dynamic process. An empirical study of the European monetary union finds that the extensive margin of trade in new goods responded several years ahead of EMU implementation and ahead of overall trade volume. A dynamic rational expectations trade model shows that early entry of new firms in anticipation is explainable as a rational forward-looking response to news. The model helps identify which types of trading frictions are reduced by a currency union, and shows how new entry can be affected by uncertainty about EMU.     

Business cycle synchronisation in East Asia: The role of value‐added trade

We empirically investigate the relationship between business cycle synchronisation and the role of value‐added trade focusing on a panel of 12 Asian countries from 1995 to 2011. In addition, we propose the inclusion of two novel determinants, for example external value‐added trade intensity and exchange rate volatility and also saturate our empirical model with other common determinants found in the literature. Our findings first confirm that value‐added trade intensity, rather than gross trade intensity, has a sizable, positive and statistically significant impact on synchronisation among East Asian countries. Second, the exchange rate volatility has a significant negative effect on the business cycle synchronisation, which verifies that the exchange rate volatility is another important determinant of business cycle synchronisation. Our findings have important implications for the monetary cooperation in the region: strengthening trade linkage could reduce the costs of monetary cooperation by increasing the incidence of symmetric shocks.     

Exchange rate expectations and monetary policy

The adjustment process to a monetary disturbance is studied in a model of perfect capital mobility and flexible exchange rates. Exchange rate expectations are emphasized and used to establish an adjustment process. In the short run, a monetary expansion gives rise to a depreciation in the exchange rate and a reduction in saving due to the terms of trade deterioration. The exchange rate depreciation, in the short run, may be in excess of the long-run depreciation. The trade balance in the short run may worsen. The long-run equilibrium of the analysis conforms to the Mundell-Fleming results that establish the force of monetary policy under flexible rates.

A model of trade in money,goods and factors

The ‘Oil Crisis’ provides the challenge to analyze effects of a resource shortage in a minimal monetary model of a vertically trading world economy. The one-asset monetary approach to balance of payments theory is employed to demonstrate that in a model with one final good and two inputs the elasticity of substitution between the domestic factor of production and an imported raw material plays the key role in determining the reaction of the balance of payments (= balance of trade).     

International trade in a system of floating exchange rates

Since the introduction of the system of floating exchange rates policy-makers have been troubled by uncertainties regarding the effects of this system on international trade. Do exchange rate changes affect trade flows? Can governments manipulate exchange rates? Have countries been “injured” by exchange rate changes? What are the real costs of international monetary instability? Answers to these key questions are given in the following article.     

Instrument rules in monetary policy under heterogeneity in currency trade

We embed different instrument rules into Galí and Monacelli’s new Keynesian model for a small open economy that is augmented with technical trading in currency trade to examine the prerequisites for monetary policy. Specifically, conditions for a determinate and least squares learnable REE are in focus. When a contemporaneous data specification of the rule is used in policy-making, the degree of trend following in currency trade does not affect these conditions, except in case of an extensive use of trend following, whereas a forward expectations specification makes it less likely to have a determinate and learnable REE when the degree of trend following is increasing. We allow for interest rate inertia in the analysis.     

Non-traded goods and optimal trade policy in a cash-in-advance economy

This paper develops a standard trade model of a small open monetary economy with two traded and one non-traded goods. Money is introduced through a generalized cash-in-advance constraint where the share of goods purchases that must be made using cash, varies across sectors. We find that free trade may be harmful so that alternative policy instruments may be considered to improve welfare. In addition, we study and compare the optimal tariff formula and the optimal consumption tax structure. In the presence of a monetary distortion of the non-traded good, a consumption tax may not Pareto dominate a tariff although the latter bears an additional production burden. This corroborates the theory of second best.     

The dynamics of trade and competition

We estimate a version of the Melitz and Ottaviano [Melitz, Marc J. and Ottaviano, Gianmarco I.P., 2008, Market size, trade, and productivity, Review of Economic Studies 75(1), pp. 295-316.] model of international trade with firm heterogeneity. The model is constructed to yield testable implications for the dynamics of prices, productivity and markups as functions of openness to trade at a sectoral level. The theory lends itself naturally to a difference in differences estimation, with international differences in trade openness at the sector level reflecting international differences in the competitive structure of markets. Predictions are derived for the effects of both domestic and foreign openness on each economy. Using disaggregated data for EU manufacturing over the period 1989-1999 we find short run evidence that trade openness exerts a competitive effect, with prices and markups falling and productivity rising. The response of profit margins to openness has implications on the conduct of monetary policy. Consistent with the predictions of some recent theoretical models we find some, albeit weaker, support that the long run effects are more ambiguous and may even be anti-competitive. Domestic trade liberalization also appears to induce pro-competitive effects on overseas markets.     

Welfare and trade elasticity with multinational production

We explore welfare properties in a firm heterogeneity model with multinational production and export. The presence of multinational production plays a crucial role in delivering a partial trade elasticity of total sales by exporters and affiliates that is no longer constant, and depends on both supply and demand parameters. We then analyse counterfactual scenarios. Multinational production with intra-firm trade increases welfare gains by up to 4% with respect to a model with only export and no truncation. Multinational production à la Helpman et al. (American Economic Review, 2004, 94 , 300) generates the largest welfare gains from liberalisation.     

The rise of vertical specialization trade

Manufacturing and vertical specialization (VS) trade, trade in goods that incorporate imported inputs, have grown rapidly since the 1960s. I argue that declining trade costs are an important explanation for these facts. I present a three stage vertical specialization trade model, with raw materials, manufactured parts and final goods sectors. In the simulated model, falling trade costs explain much of the observed growth in overall and VS trade. Manufacturing trade grows twice as fast as overall trade. Raw materials trade was more important in the 1960s when trade costs were high, since their production is more strongly linked to endowments than manufacturing. Therefore, materials will be traded even when trade costs are high. Trade costs have fallen more for manufactured goods over the last 40 years, leading to a rapid expansion of manufactured parts trade relative to materials.     

A theory of the currency denomination of international trade

The currency denomination of international trade has significant macroeconomic and policy implications. In this paper we solve for the optimal invoicing choice by integrating this microeconomic decision at the level of the firm into a general equilibrium open economy model. Strategic interactions between firms play a critical role. We find that the less competition firms face in foreign markets, as reflected in market share and product differentiation, the more likely they will price in their own currency. We also show that when a set of countries forms a monetary union, the new currency is likely to be used more extensively in trade than the sum of the currencies it replaces.     

Customs union theory and the nonuniformity of tariffs

Allowance is made for the initial nonuniformity of the tariffs of a union country before it joins a customs union. The reduction of such nonuniformity is a possible source of welfare again distinct from the usual trade creation and trade diversion effects. A net welfare gain from a union may result even when the country's total trade stays unchanged and even when all trade with the outsider ceases. A three-product, small-country model is used, domestic production and consumption substitution between the two importables yielding the import pattern effect that produces the possible gains referred to.     

Repeated games and the ‘reciprocal dumping’ model of trade

A repeated game version of the basic Brander and Krugman (1983) model is analyzed. In the Brander-Krugman model, rivalry among oligopolistic firms gives rise to international trade. It is now shown that no trade, which is welfare-reducing when transportation costs are negligible, is a strong Nash equilibrium of the supergame. The threat strategies that support ‘no trade’, the discount rate, and the crucial role of transportation costs are discussed, extending the BranderKrugman analysis in a natural way.     

贸易战还是货币战:论跨境贸易人民币结算

从2009年7月1日,将上海、广州、深圳、珠海和东莞作为跨境贸易人民币结算的境内试点区.港澳地区和东盟国家作为境外试点区到2010年6月以来,境内试点地区已扩大至全国20个省,境外地城扩展到所有国家和地区,跨境交易人民币结算试点业务扩大至所有经常项下.至此,中国也迈上了主权货币国际化之路.那么为什么国家都热衷于推动本国货币成为世界结算货币,进而取得国际货币发行权呢?中国选择的这条路又有着怎样的前景呢?我将从贸易战与货币战的角度来解答.     

Foreign monetary shocks,differentiated products and international transmission: a two-country model with intra-industry trade

In this paper we study how the impact of a foreign monetary shock is transmitted between two monopolistically competitive economies engaging in intra-industry trade with differentiated products. Intra-industry trade is the only international link that works through the flexible exchange rate affecting national price levels and a product's internal and external relative prices. While national price levels are subject to purchasing power parity, the two relative prices are determined by the interaction between macro and micro variables. In this context, the exchange rate can insulate a national economy perfectly from a foreign monetary shock provided that monopolists adjust prices. Even if monopolists keep prices rigid, this shock only affects domestic real balances and aggregate demand, leaving domestic aggregate output unchanged because the real balances effect is just offset by the resulting unfavorable relative prices effects under the assumption of Spence-Dixit-Stiglitz preferences.     

The Niehans paradox,flexible exchange rates,and macroeconomic stability

This paper re-examines Dornbusch's suggestion that monetary expansion under a floating rate system will not cause a temporary decline in economic activity — the Niehans paradox — because households will cut their saving to maintain consumption spending on domestic goods. Despite this terms of trade effect on saving, it turns out that devaluation in the standard Keynesian model, in which trade flows, however, respond to the exchange rate with a simple distributed lag, produces a temporary decline in economic activity under certain plausible conditions. Consequently, the Niehans paradox still can arise if domestic expenditures respond sluggishly to lower interest rates.     

Regional bloc formation and world trade

The grouping together of neighbouring countries to form free trade areas or economic and monetary unions currently constitutes a phenomenon occurring in all regions around the world. How far has the bloc-building process progressed? How will the development of world trade be affected by this process during the 1990s? How can companies respond to the developments in the global marketplace?     

国际贸易环境下我国对外贸易政策的发展方向

近十几年来,全球贸易量取得了惊人的跨越式增长,而自由贸易与环境的关系问题也日趋尖锐。一方面,许多发达国家利用不对等的贸易和投资手段从发展中国家攫取大量战略性资源,却造成这些国家境内生态环境的严重失调;另一方面,一味地追求贸易扩张、资金积累和工业化又实际加剧了全球环境的恶化。环境效应对贸易的挤压性制约日益上升为国际贸易发展的焦点。在此背景下,引入环境变量,促进贸易策略的可持续性便成为实现我国对外贸易科学发展的必然之路。
