Airplanes and comparative advantage

Airplanes are a fast but expensive means of shipping goods, a fact which has implications for comparative advantage. The paper develops a Ricardian model with a continuum of goods which vary by weight and hence transport cost. Comparative advantage depends on relative air and surface transport costs across countries and goods, as well as stochastic productivity. A key testable implication is that the U.S. should import heavier goods from nearby countries, and lighter goods from faraway counties. This implication is tested using detailed data on U.S. imports from 1990 to 2003. Looking across goods the U.S. imports, nearby exporters have lower market share in goods that the rest of the world ships by air. Looking across exporters for individual goods, distance from the US is associated with much higher import unit values. These effects are large, which establish that the model identifies an important influence on specialization and trade.     

Product specialization in international trade: A further investigation

In an influential paper, Schott [Schott. Peter K. (2004). “Across-product versus within-product specialization in international trade.” Quarterly Journal of Economics, 119 (2): 647–678] makes two empirical observations about U.S. imports. (1) The United States is increasingly sourcing the same product (however narrowly defined) from both developed and developing countries. That is, ‘across-product specialization’ has been decreasing. (2) The unit values of these multiple-sourced products are positively and significantly correlated with the capital and skill abundance of exporters and with the capital–labor ratios used by exporters. That is, endowments-driven ‘within-product specialization’ has been increasing. We show that both these observations extend to the imports of Brazil, India and Japan. However, our main finding is that observation (1) is largely driven by two factors. First, China is the dominant low-wage exporter of multiple-sourced products. Second, the most developed countries remain the primary exporters of multiple-sourced products. The U.S. case is the most extreme of our four importers: When China is deleted from the U.S. import data there is no trend in across-product specialization and rich exporters are increasing their trade share of multiple-sourced products. Since deleting China has no theoretical justification, these results must be viewed not as a contradiction of Schott's work but as a way of deepening our understanding of his empirical results.     

美国反倾销贸易保护效应的实证分析

通过建立美国各年向各涉案国家的进口额与反倾销申诉、反倾销措施及相关影响因素的回归模型,考察了1995-2008年美国发起的反倾销申诉和采取的反倾销措施对所有57个涉案国家和地区进口的影响.运用广义矩法对最小二乘估计的结果进行修正发现,虽然美国当期的进口主要由历史进口因素决定,但其反倾销申诉与措施会造成当期进口总额的显著下降,下降比例分别达到7.198%和5.890%,美国反倾销保护效应使美国年均进口额下降近1757亿美元,中国每年向美国的出口额减少超过127亿美元.     

Market Structure and Market Access

We explore an issue at the nexus of domestic competition policy and international trade, the interaction between goods trade and market power in domestic trade and distribution sectors. We examine the effect of variations in conditions of domestic competition in services on trade volumes in goods in the cases of both linear and nonlinear import demand, including standard form CES‐based gravity models of bilateral trade flows. Theory suggests a set of linkages between service‐sector pricing and goods trade supported by econometrics involving imports of 22 OECD countries vis‐a‐vis 69 exporters. Competition in distribution services affects the volume of trade in goods. Additionally, because of interaction between tariffs and pricing, the market structure of the domestic service sector becomes increasingly important as tariffs are reduced. Indeed, depending on the degree of competition, market access concessions on tariffs may be effectively undone in some cases by changes in margins. For exporters, we find that service competition in destination markets matters most for exporters from smaller, poorer countries. Our results also suggest that while negotiated agreements leading to cross‐border services liberalisation may boost goods trade as well, they may also lead to a fall in goods trade when such liberalisation involves FDI leading to increased service sector concentration.     

Import Demand Elasticity and Exporter Response to Anti-Dumping Duties

ABSTRACT

This article investigates exporting firms’ behavior following the imposition of anti-dumping (AD) duties. AD duties tend to increase the prices of imported goods via a mechanism different from any other trade barrier because the AD duty size is endogenously dependent on import prices. Our model accounts for this feature and demonstrates that exporters are more likely to adjust their price upward when they face a less elastic demand. The theoretical predictions are supported empirically by relating product-level U.S. import demand elasticities and exporting firms’ reactions to duties inferred from a dataset on U.S. AD investigations from 1980 to 1995.     

Bilateral Trade under Environmental Pressure: Balanced Growth

Based on the advance-retreat course (ARC) model - a growth model under environmental pressure, this paper builds a bilateral import and export trade growth model under environmental pressure. By using the model, the paper analyzes the impacts of innovation on import and export growth, presents a method for computing the optimal levels of imports and exports, derives the limit values of imports and exports, and obtains the limit equilibrium between exports and imports. Finally, a strategy for promoting import and export growth and achieving a bilateral trade balance according to the limit equilibrium is designed. The findings are the following: (i) innovation growth will gradually reduce goods import and export, and services import and export will increase, (ii) the U.S. import–export structure is more reasonable than that of China, and (iii) there is big room for services import and export growth for China.     

Imports and Exports at the Level of the Firm: Evidence from Belgium

This paper explores a newly available panel dataset merging balance sheet and international trade transaction data for Belgium. Both imports and exports appear to be highly concentrated among few firms and seem to have become more so over time. Focusing on manufacturing, we find that facts previously reported in the literature as applying only to exports actually apply to imports too. We note that the number of trading firms diminishes as the number of export destinations or import origins increases. The same is true if we consider the number of products traded. Our results generally point to a process of self‐selection in both export and import markets. Also, the productivity advantage of exporters reported in the literature may be overstated because imports were not considered. We find that firms that both import and export are the most productive, followed, in descending order, by importers only, exporters only and non‐traders. Our results also show the existence of fixed costs of imports, which appear to be of similar magnitude as those of exports.     

Resource Structure and Imports: An Analysis of the Relationship between Skill-Intensive Imports and Skill Endowment

Countries generally import those goods which they do not produce, and there is a possibility that this might be due to unavailability of resources needed to produce the goods which the countries import. Hence, countries with lower levels of total skill endowment are supposed to import more skill-intensive goods than countries with higher levels of total skill endowment. However, the presence of vertical and horizontal intra-industry trade makes this picture complex. Using a theoretical model derived on the basis of earlier theories and some empirical investigation on data of 72 countries of 3 years, this article tries to find out whether there is any relation between total skill endowment and imports of a country. The results show that there is indeed a relationship, but the nature of this relationship depends on the effect of total skill endowment on the country's skill-intensive exports as well.     

PROMOTING EFFORTS FROM DEVELOPING COUNTRIES: AN EMPIRICAL TEST OF THE IMPACT OF IMPORT PROMOTION OFFICES

Increasing exports from developing countries is widely regarded as an important part of a development and growth strategy. A major problem confronting exporters from developing countries is the many market barriers they typically face when attempting to enter markets in developed countries. Different institutions have been established to alleviate this problem, including export promotion offices (EPOs) in various developing countries and import promotion offices (IPOs) in several developed countries. The present study explores the impact of IPOs on exports from developing to developed countries by examin ing the actual pattern of imports into OECD countries over the period 1988 to 1993. Four specific product groups are selected and a model pertaining to explain the pattern of imports is presented. The results show that, even after controlling for a number of economic and policy variables, the share of imports originating in developing coun tries is indeed positively influenced by the presence of an IPO in the importing country. Thus, the results suggest that the establishment of an IPO may have a positive impact on the share of imports originat ing in developing countries.     

Geographical disadvantage: a Heckscher-Ohlin-von Thünen model of international specialisation

We analyse the trade and production patterns of countries located at varying distances from an economic centre. Exports and imports of final and intermediate goods bear transport costs which increase with distance. We show how production and trade depend on factor endowments and factor intensities, and also on countries’ locations and the transport intensities of different goods. Countries divide into zones with different trade patterns, some export oriented and others import substituting. We study the implications of distance for factor prices and real incomes, the effects of changes in transport costs, and the locational choice of new activities.

International trade in durable goods: Understanding volatility, cyclicality, and elasticities

Data for OECD countries document: 1. imports and exports are about three times as volatile as GDP; 2. imports and exports are pro-cyclical, and positively correlated with each other; 3. net exports are counter-cyclical. Standard models fail to replicate the behavior of imports and exports, though they can match net exports relatively well. Inspired by the fact that a large fraction of international trade is in durable goods, we propose a two-country two-sector model in which durable goods are traded across countries. Our model can match the business cycle statistics on the volatility and comovement of the imports and exports relatively well. The model is able to match many dimensions of the data, which suggests that trade in durable goods may be an important element in open-economy macro models.     

The effect of exchange rate uncertainty on the prices and volume of international trade

By specifying a model of differential risk-bearing by import demand and export supply sides of the market for traded goods, the theoretical impact of exchange risk on both equilibrium prices and quantities is analyzed. For several empirical cases of 1965–1975 U.S. and German trade it is found that exchange rate uncertainty has had a significant impact on prices but no significant effect on the volume of trade. These price effects support previous survey results on the currency denomination of export contracts, namely that with the exception of some U.S. imports, most trade is largely denominated in the exporter's currency.     

Exchange Rate Pass-Through and the Role of Market Shares

This paper examines the effects of changing market shares on exchange rate pass-through to US import prices. Based on a static model of imperfect competition, I predict that a country with a larger share of a host’s import market will have lower pass-through than its competitors. Using highly disaggregated data on US imports, I implement rolling regressions to calculate unique quarterly values of pass-through for specific goods from each exporting country. These values are compared across market shares, indicating a general trend of decreasing pass-through for larger shares. Most specifically, as predicted by the model, the country holding the largest share of the market has significantly lower pass-through than its competitors. The negative relationship between pass-through and market share holds across most categories of goods, most notably the larger categories of imports. Lastly, I show the market share effect is stronger following larger fluctuations in the exchange rate, particularly after large dollar appreciations.     

三角贸易模式对中国对美出口增长的影响

中国在国际生产网络中的地位日益突出,主要扮演着加工装配地的角色,即从日本、韩国等工业化国家或地区进口中间品,经过加工装配后再将最终产品出口至以美国、欧盟为主的发达国家或地区,从而形成了三角贸易模式。中国对美出口的快速增加与三角贸易模式的发展密切相关,文章研究表明,中间品进口的增加和三角贸易模式的发展显著地促进了中国对美出口的增加,因此中美贸易失衡主要不是一种双边贸易现象,而是一种结构性现象。     

Gains and Losses from Preferential Trade Agreements: Some Evidence from NAFTA

In this article we integrate two topics in international trade policy that have received (separately) a lot of attention: the effects of regional trade blocs, and export pessimism regarding poorer countries. The specific issue that allows us to bring together these questions is whether regional integration adversely affects non-members. We use quarterly data on bilateral trade flows for the period 1990 through 1997 to examine U.S. imports from its NAFTA partners as well as from non-NAFTA trade partners, and more specifically, those countries expected to be hurt by NAFTA. Two measures are used:

1. “import penetration” or imports from a particular source as a share of US GDP, and

2. the income elasticity of expenditure on imports from a particular source. Both “import penetration” and the income elasticity of expenditure affect the export earnings of U.S. trade partners, a matter of particular concern for developing countries.

The broadest pattern observed in the income-expenditure elasticities is clear evidence of increased penetration by non-oil developing countries. This is in marked contrast to the stable GDP share and expenditure elasticity for developed country imports. Regional results suggest that the Caribbean and the East Asian NICs were the only area groupings that experienced a reduction in income-expenditure elasticity. But overall on the basis of U.S. income-expenditure elasticities it appears that the first four years of NAFTA were associated with trade expansion rather than trade diversion.     

The Impact of the U.S. Bio-Terrorism Act upon Canadian Exporters of Food Products to the United States: A Firm-Level Analysis

This article examines the impact of the 2002 U.S. Bio-terrorism Act (BTA) upon Canadian exporters of food products to the United States. A major goal of the BTA is to secure U.S. ports of entry against imports that might threaten the health or safety of U.S. citizens. Although this is a respectable goal, data from a sample of 144 Canadian exporters suggest that the BTA represents a non-tariff barrier to Canada-U.S. trade. Current regulatory procedures have disrupted cross-border supply chains in significant ways. These disruptions have damaged the Canada-U.S. commercial relationship by imposing extra shipment and distribution costs upon Canadian exporters. These delays have had a serious impact upon small-to-medium sized firms (SMFs). The article concludes with a brief discussion of possible remedial actions that might be taken by Canadian exporters.     

“The bigger they are, the harder they fall”: Retail price differences across U.S. cities

This paper examines the evidence for nonlinear price behavior in retail goods prices across U.S. cities. First, a simple continuous-time model is used to explore the types of price behavior that can arise in the presence of market frictions. These frictions could be interpreted as transport costs, but we prefer a broader interpretation in which they operate at the level of technology and preferences. Second, we gather price data from 24 U.S. cities on individual goods like orange juice and toothpaste. The empirical analysis reveals that price discrepancies between U.S. cities are stationary and nonlinearly mean-reverting to price parity.     

Movies and the Mystery of the Missing Trade: Is Hollywood Good for U.S. Exporters?

Research has shown that consumers have a preference for goods based on the origin of production. This is important because it suggests that, in some cases, even lowering trade barriers may not significantly increase trade flows. In particular, flows may be lower than are predicted by trade theories such as Heckscher-Ohlin. Despite evidence that home consumption bias exists in many countries, it is only recently that research has begun to examine the sources of this bias.

This article fills a gap in the literature by testing a model that addresses the source of this consumption bias. The paper's model incorporates consumers' exposure to foreign products and culture through media imports and tourist visits as factors affecting consumers' preferences for foreign products. Using panel data from 19 countries, the article's results support the hypothesis that lagged exports of U.S. movies have a positive impact on other U.S. exports. Some evidence is also found of a positive effect of tourist visits on U.S. exports.

Since U.S. media exports may generate demand for other U.S. goods and services, opening up foreign media markets should receive a higher priority in U.S. trade negotiations. Another interesting implication of the paper is that overall U.S. export losses resulting from media piracy may be lower than previously calculated, as the consumption of pirated media products may increase demand for other U.S. exports.     

The role of expenditure switching in the global imbalance adjustment

In theory, nominal exchange rate movements can lead to “expenditure switching” when they generate changes in the relative prices of goods across countries. This paper explores whether the expenditure-switching role of exchange rates has changed in the current episode of significant global imbalances. We develop a multi-sector two-country model for the United States and the G6 countries, with the rest of the world captured by exogenous price and demand shocks, and estimate the model over two sub-samples, which cover the periods before and after the early 1990s. Our results indicate that both U.S. imports and exports have become much less responsive to exchange rate movements in recent years, mainly due to changes in firms' pricing behavior and global trade pattern. These findings suggest that the exchange rate would have to move by a much larger amount now than in the 1970s and 1980s to reduce the U.S. trade deficit by a given amount.
