Gains and losses from potential bilateral US–China trade retaliation

Two closely related numerical general equilibrium models of world trade are used to analyze the potential consequences of US–China bilateral retaliation on trade flows and welfare. One is a conventional Armington trade model with five regions, the US, China, EU, Japan and the Rest of the World, and calibrated to a global 2009 micro consistent data set. The other is a modified version of this model with monetary non-neutrals and including China's trade surplus as an endogenous variable.Who may gain or loss from global trade conflicts spawned by adjustment pressures in the post crisis world is much debated. In a US–China trade conflict, Europe and Japan would seem gainers from preferential access to US and Chinese markets. The loss of markets would hurt the US, but moving closer to an optimal tariff could be the source of terms of trade gains. And the ease of substitution across trading partners' practices would determine costs for China.Results from the conventional model suggest that retaliation between the two countries can be welfare improving for the US as it substitutes expenditures into own goods and improve its terms of trade with non-retaliatory regions, while China and non-retaliatory regions may be adversely affected. Results in the endogenous trade surplus model from the central case model specification, however, suggest that both the US and the EU (the deficit regions) have welfare losses in most cases, while the surplus region, China, and the ROW have welfare gains. In both models, when the bilateral tariff rates are very high, gains accrue to the EU and Japan from trade diversion if the substitutions elasticities of imports are high. Costs are borne by the US and China in lost exports, lowered terms of trade and adjustment costs at home.     

不同贸易方式技术溢出效应的比较——基于我国1987-2008年数据的实证研究

本文运用协整理论检验了我国1987-2008年间加工贸易进口和一般贸易进口的技术溢出效应.实证结果表明,加工贸易进口和一般贸易进口的技术溢出均对我国生产率起到了显著的促进作用,并且加工贸易进口的正向技术溢出效果远大于一般贸易进口的正向技术溢出效果.同时,加工贸易进口和一般贸易进口的技术溢出效应虽然长期显著地促进了我国生产率的增长,但这种正向技术溢出效应在短期内呈现出一定的滞后性.由于加工贸易进口在租金溢出效应、竞争效应与人力资本流动效应上的优势使得加工贸易进口的技术溢出效应大于一般贸易进口的技术溢出效应.     

Global trade flows and economic policy uncertainty

ABSTRACT

This article investigates the impacts of economic policy uncertainty (EPU) on global trade flows in gauging international trade developments. We employ a global vector autoregressive (GVAR) trade model, augmented with value-added bilateral trade linkages, that allows for quantifying the effects of economy-specific uncertainty shocks on exports and imports of individual economies. We find substantial spatial propagation in the temporal dynamics of international transmission of shocks amidst the manifestations of cross-border global value chains (GVCs) with China’s accession into the WTO. We provide evidence for the significance of EPU of China and the United States, particularly the latter, in influencing global trade flows. Our results show that while the US impacts can largely be attributed to its indirect trade linkages with other economies, the impacts of China can be relegated more to its direct GVC linkages. The findings have implications on trade protectionist inclinations of the current-term US government and the ongoing efforts of China’s policymakers in steering macroeconomic rebalancing for sustainable growth.     

Have Falling Tariffs and Transportation Costs Raised US Wage Inequality?

To gauge the effect of international trade on the rising US skill premium, the paper analyzes the sector bias of price changes induced by changes in US tariffs and transportation costs. It is found that, in both the 1970s and 1980s, cuts in tariffs and transportation cost levels were concentrated in unskilled‐intensive sectors. Despite this suggestive evidence, the authors estimate that price changes induced by tariffs or transportation costs mandated a rise in inequality that was mostly statistically insignificant. Thus, they do not find strong evidence that falling tariffs and transport costs, working through price changes, mandated rises in inequality.     

China Bashing: Does Trade Drive the “Bad” News about China in the USA?

A monthly index of “bad” news about China as reported in the USA from January 1990 to December 2008 is developed in this paper. “Bad” is defined as news touching on the following issues: human rights, Tibet, child labor, democracy, and repression. Using this bad news index, this paper documents a peculiar finding: 3–4 months after a trade deficit shock to the US–China bilateral trade balance, the frequency of bad news published about China by US media outlets rises sharply, then dies off slowly. Statistical analysis reveals that the likelihood that this finding is just a coincidence is relatively small—about 1%. In addition, this paper finds a robust association between the annual number of Congressional hearings on China and the US–China bilateral trade deficit. These results suggest that “China bashing” may be endogenous to fluctuations in the US–China bilateral trade balance.     

The economic effect of the Canadian BSE outbreak on the US economy

Before the discovery of the first Bovine Spongiform Encephalopathy (BSE) cow in May 2003, Canada was the most important exporter of live cattle into the US with a share of 74% of US total live cattle imports. With the outbreak of BSE in Canada, the US ceased imports of Canadian cattle and beef products. This study analyses the short to medium-term effect of the import trade ban for the US economy using a 20 sector, economy wide Computable General Equilibrium (CGE) model. Uncertainty about exogenous elasticity values was addressed using Monte Carlo techniques. Beneficiaries of the trade ban are the cattle industry and related sectors, such as feed production and agricultural service providers. The US economy as a whole, however, is negatively affected with a loss of ～$-1.7 billion in gross domestic product and –11000 jobs. The model shows how the restriction on Canadian cattle imports generates income losses for both rich and poor households in the US.     

Distorted Trade Barriers: A Dissection of Trade Costs in a “Distorted Gravity” Model

It is common in the trade literature to use iceberg transport costs to represent both tariffs and shipping costs alike. However, in models with monopolistic competition these are not identical trade restrictions. This difference is driven by how the two costs affect the extensive margin. We illustrate these differences in a gravity model. We show theoretically that trade flows are more elastic with respect to tariffs than transport costs and find a linear relationship between the elasticities with respect to tariffs, iceberg transport costs, and fixed market costs. We empirically validate these results using data on US product‐level imports.     

Transportation Costs and US Manufacturing FDI

In empirical models of foreign direct investment (FDI), distance is most often used to proxy for transportation costs and other pure‐trade costs. Given that distance is time invariant but transportation costs are not, this approach is less than satisfactory when actual transportation costs rise and fall over time.The contribution of this work is to explicitly control for transportation costs and thereby better understand their impact on FDI. We explore the impact of shipping costs on total US FDI stocks abroad, manufacturing stocks and service stocks using measures of sea‐shipping and air‐shipping costs in a Hausman–Taylor model that controls for endogeneity and allows for time‐invariant variables such as distance. We find that transportation costs have a positive and statistically significant relationship with US total and manufacturing FDI, suggesting a substitute relationship between FDI and trade flows consistent with horizontal MNE activity. As one would expect, these costs are insignificant for service stocks.     

The China–United States Bilateral Trade Balance: How Big Is It Really?

There are huge discrepancies between the official Chinese and US estimates of the bilateral trade balance. The discrepancies are caused by different treatments accorded to re-exports through Hong Kong, re-export markups, and trade in services. Deficit-shifting between China, on the one hand, and Hong Kong and Taiwan, on the other, owing to direct investment in China from Taiwan and Hong Kong, is partly responsible for the growth in the China–US bilateral trade deficit. The 1995 China–US bilateral balance of trade in goods and services, adjusted by both re-exports and re-export markups, may be estimated as US$23.3 billion, a large deficit but considerably smaller than the often-cited official US figure of US$33.8 billion.     

国际石油价格与通货膨胀的溢出效应及动态相关性

国际石油价格大幅波动不可避免地给全球经济带来了一定程度的冲击和影响。文章采用向量自回归、多元GARCH-BEKK和DCC-GARCH模型对中美两国通货膨胀与国际石油价格之间的均值溢出效应、波动溢出效应及动态相关关系进行了实证检验。检验结果表明,国际石油价格与中国通货膨胀不存在任何方向的均值和波动溢出效应,美国通货膨胀与国际油价则存在双向显著的均值和波动溢出效应;中国通货膨胀与国际油价的动态相关关系显著弱于美国,不易受到国际油价的冲击和影响。从整体上看,当前中国通货膨胀与国际石油价格的关联性并不显著,但随着我国石油消费对进口依赖程度的不断提高,石油安全问题在可预见的未来将成为中国需要应对的一个现实挑战。因此,相关部门应及早采取有效措施,应对未来石油冲击对宏观经济的影响。     

美国贸易逆差:增长惯性与可持续性

美国的经常项目逆差特别是贸易逆差“历史悠久”,尤其是近年来高速增长,已引起人们广泛的关注。本文作者认为:20世纪90年代以来的美国贸易逆差已很难单从汇率、贸易政策及产品竞争力等单个变量来加以解释。通过运用滞后一年的时间数列相关分析及回归分析,本文得出的结论是:当期美国贸易逆差是前期美国贸易逆差的惯性增长,并且只要美国资本与金融账户的盈余足够冲抵贸易逆差,美国的贸易逆差便具有可持续性。针对近期美国人制造的“人民币升值论”,结合近十年来中美双边贸易现实,说明美国贸易逆差与人民币汇率之间没有必然联系,人民币升值也不可能改善美国的贸易收支状况。     

Rebalancing through expenditure and price changes

This paper puts forth a Neo-Kaleckian open economy model of two countries in order to investigate adjustment of US–China external imbalances. First, a stylized fixed mark-up model is presented, and discussed based on graphical analysis. Second, we present estimates of bilateral income and price elasticities of imports. Third, we employ the model for simulation analysis. Specifically, we randomly distribute expenditure change across government, investment and imports and calculate the exchange rate change necessary to lead to an equal change in the bilateral external imbalance. Doing so repeatedly allows us to estimate probability distributions of endogenous variable changes.     

Port Efficiency and Trade Flows*

Growing international trade and increasing congestion focus attention on trade facilitation. Ocean ports are a central and necessary component in facilitating trade. Yet, there is only limited comprehensive information available on the efficiency of ports or evidence of the effect of port efficiency on trade. We develop and apply a straightforward approach to estimate port efficiency. The approach uses detailed data on US imports and associated import costs, yielding estimates across ports, products, and time. These measures are incorporated into a gravity trade model where we estimate that improved port efficiency significantly increases trade volumes.     

Investment in trade facilitating infrastructure: A political-economy analysis

This paper analyzes public investment in infrastructure that facilitates international trade. It considers a world consisting of small open economies that face transport costs for exporting or importing a particular good. Transport costs can be lowered by an improvement in transport infrastructure. National governments non-cooperatively decide about their respective country's investment level. Governments' preferences are assumed to be biased in favor of producers' interests with consequences for equilibrium investments: Exporting countries, whose producers benefit from a transport cost reduction, spend more for infrastructure than importing countries, whose producers are protected by transport costs from foreign competition. This outcome is inefficient, and governments have an incentive to cooperate internationally. The paper also incorporates bilateral trade with two goods that benefit from infrastructure improvements as well as trade that results from offshoring.     

Trade and Rural-Urban Income Inequality: Evidence from China

Using the provincial panel data from 1978 to 2007, this paper makes an empirical analysis of the relationship between international trade and rural-urban income inequality in China. The results show that international trade has a fundamental impact on rural-urban income inequality. For the whole country, the development of international trade from 1978 to 2007 enlarged the rural-urban income gap. During the three different periods (defined in section 3.3), the impact was also noticeable in terms of extent, direction and significance respectively at the national and regional levels. During the three periods, the relationship has an inverted “U” shape for China as a whole, central China and western China, but for eastern China the relationship has a “U” shape. At the same time, exports and imports have different influences on the rural-urban income gap in China, the influences were also different across regions; and the imports has had a more significant influence on these regions than exports has had.     

China's Exchange Rate Policy and Its Trade Balance with the US

This paper investigates the claim that China's exchange rate policy causes the US trade deficit with China to grow. Although there is no evidence that changes in the exchange rate cause the trade deficit to rise in the short run, a statistically significant long‐run relationship between the RMB/dollar exchange rate and the US trade deficit with China is detected. As the value of the dollar declines (or RMB appreciates), ceteris paribus, so does the trade deficit. Hence, there is a need for China to adjust its exchange rate policy to help reduce the ever mounting US trade deficit.     

影响中美贸易的诸因素分析

本文采用2001年1月～2008年12月样本,在双边贸易引力模型的框架下,采用协整分析、向量误差修正模型等计量方法,在汇率和中美两国GDP等影响因素基础上,分析中国垂直专业化对于中国对美出口、中国自美进口和中美贸易差额的影响。研究结果表明,中国垂直专业化程度不断加深促进了中国对美出口、抑制了中国对美进口,加剧了双边贸易的不平衡。     

贸易统计差异与中美贸易平衡问题

本文研究发现(1)中美进出口计价方式不同和运输时滞导致双边贸易统计数据存在差异是自然的。(2)参照剔除香港转口毛利后中美贸易新估计值,1995—2003年美国对华出口低估年均在24%以上,从华进口高估年均在35%以上,而中国对美出口低估年均在20%以上,从美进口相对没变。(3)考虑服务贸易后,美中商品与服务贸易逆差估计值与中国对美贸易顺差新估计值已相当接近。上述结果得到IMF数据的证实。(4)外商在华直接投资增加会造成中国对美出口增加、对美贸易顺差增加。依据中美两国月度数据计量的结论是相一致的。这一结果证实中美贸易平衡问题已超越中美两国贸易范围而成为外商在华直接投资所引致的贸易逆差转移问题。剔除外资企业进出口贡献及贸易统计差异后,中国对美贸易估计值已非常趋近于美国对华贸易估计值。     

Microeconomic analysis on the growth of trade volume in China: 1978–2007

The gravity equation is usually employed by researchers in the field of international trade to explain the growth of a country’s imports and exports volume, especially the manufactured goods. But in China, variables in the model, such as exchange rate, tariff, transportation cost, and spatial distance etc., are not sufficient to explain the riddle of China’s growth in trade volume. In fact, this growth in China’s trade volume is owing to the disintegration of production in the process of economic globalization, to the multinational corporations’ (MNC) vertical outsourcing of their manufacturing processes and procedures, and to the timely readjustment of Chinese enterprises on their strategies of participating in the international intra-product specialization. In this paper we establish an equilibrium model of intra-product specialization dominated by MNCs, and do some empirical tests on the growth in trade volume in China by using the variables including technological conditions of trade, similarity of economies, policy conditions of trade, disintegration of production and level of per capita capital equipment. The empirical results support our basic judgments.     

基于贸易收支数据的美国贸易逆差与美元汇率相互关系研究

通过选择美国与中国、日本、加拿大、英国和欧元区11国等美国主要贸易伙伴的双边贸易数据作为样本,研究美国的双边贸易逆差与美元汇率之间的关系.实证分析表明,美国对主要贸易伙伴国的双边贸易收支与美元汇率没有实质性联系.美国逼迫其它货币升值没有也不能缓解美国的贸易逆差问题,同样,美国逼迫人民币升值也不能缓解美中双边贸易失衡问题.
