A Partial Equilibrium Analysis of Trade with Decreasing Transport Costs

Decreasing transport costs are incorporated in the standard partial equilibrium analysis of trade by allowing the divergence—introduced by transport costs—between export and import price to decrease with the volume of trade. When the excess demand (supply) curve is steeper than the long run average cost curve for imports (exports), we observe that an import (export) tariff raises (lowers) the domestic price by an amount exceeding the tariff. Further, when the excess demand (Supply) curve is less steep than the long run average cost curve for imports (exports), the possibility exists that an import (export) tariff may lower (raise) the domestic price. These results lead to the important conclusion that tariffs cannot be used as measures of nominal protection across industries. [F10]     

反倾销措施的贸易救济效果评估

本文利用1997—2004年中国反倾销案例8位数税则号的涉案产品数据,考察了反倾销措施引起的指控对象国和非指控对象国的贸易模式的变化,在此基础上提出了反倾销行为贸易救济效果的证据。检验结果表明,中国反倾销措施对指控对象国的进口有明显的“贸易限制效应”;不仅征税案例,即使是无损害结案的反倾销指控仍然对指控对象国的进口贸易有重要影响,即反倾销具有“调查效应”;但是涉案产品可能在指控对象国和非指控对象国之间转移,这种“贸易转移效应”部分削弱了反倾销措施的保护效果;总体上看,反倾销仍然起到了救济本国产业的作用,因为无论是指控对象国还是非对象国的进口价格都会上升,从而控制了中国涉案产品的进口总量。     

BILATERAL TRADE RELATIONSHIP BETWEEN THE UNITED STATES AND CANADA: IMPLICATIONS OF THE FREE TRADE AGREEMENT

This study's primary objective is to evaluate empirically the economic effects of the U.S.-Canada Free Trade Agreement (FTA). The paper emphasizes bilateral trade flows of agricultural and industrial products between the United States and Canada, given that the FTA removes tariff and non-tariff barriers. It evaluates the FTA's impact on the two countries' trade with third countries. The paper specifies a traditional log-linear trade model consisting of import demand and export supply equations for both agricultural and industrial products. It uses quarterly time-series U.S. and Canadian trade data for 1972–1985.
The study uses the two-stage least-squares estimator to estimate the models. The models had R coefficients ranging from 0.78 to 0.99, indicating that the models' explanatory variables explain most causes of variations in the dependent variable. This study reveals that U.S. imports of agricultural and industrial products from Canada were more sensitive than were Canadian imports not only to import and domestic prices but also to world prices. This is because Canadian consumers have less domestic substitutes than do their U.S. counterparts. Also, Canada has a smaller internal market than does the United States. The study estimates that U.S. imports from Canada will increase $2.8 billion while Canadian imports from the United States will increase $1.2 billion. The impact on the two countries' trade with third-party countries will be insignificant.     

Imports, entry and competition law as market disciplines

Numerous countries have adopted or strengthened competition laws in the past two decades. At the same time, domestic industries in most countries are facing ever more intense pressure from imports. In this paper we study the impact of competition law on domestic competition for a large number of countries over time, controlling for the presence of imports and the number of domestic firms. We find that while industries that have higher import exposure or larger numbers of domestic firms tend to be more competitive, the direct effect of competition law on competition is insignificant. However, we also find that industries that operate under a competition law tend to have a larger number of domestic firms. This suggests that competition laws may have an indirect effect on domestic competition by promoting entry.     

THE WTO AND ANTIDUMPING IN DEVELOPING COUNTRIES

Since the 1995 inception of the World Trade Organization (WTO), developing countries have become some of the most frequent users of the WTO-sanctioned antidumping (AD) trade policy instrument. This paper exploits newly available data to examine sector-level use of nine of the major "new user" developing countries, matching data on production in 28 different three-digit ISIC industries to data on AD investigations, outcomes, and imports at the six-digit Harmonized System product level. We present economically significant evidence consistent with theory that developing-country industries that seek and receive AD import protection are responding to macroeconomic shocks, exhibit characteristics consistent with endogenous trade policy formation, and face some changing market conditions consistent with requirements of the WTO Antidumping Agreement. However, the evidence also suggests substantial heterogeneity in determinants of AD use across developing countries, which highlights the flexibility of this policy as a protectionist tool responsive to many different types of political-economic shocks.     

The supply and demand for imports and exports in a simultaneous model

Previous studies on the behaviour of aggregate exports and imports have tended to ignore the simultaneous relationship between quantity and price. This paper investigates the price responsiveness of export and import demand and supply in eight African countries. The results indicate that export demand price elasticities are smaller when the sample is African. The import supply and demand elasticities were found to be generally large. The Marshall–Lerner condition of balance of payment stability is found to be easily satisfied. A positively sloped function of export supply is found to exist for a majority of countries in the sample. The average time lag of export supply is found to be about a year. The disequilibrium model is found to be more appropriate for import demand, import supply and export supply.     

大豆需求与全球资源的优化配置

供求决定价格,价格又反过来影响供求平衡.一方面,中国对大豆的进口需求是导致国际价格不断上涨的主要原因;另一方面,中国水产品出口价格的下降又刺激了美、日、韩等国对我国大虾消费的需求.大豆豆粕是大虾饲料的主要成分,欧美水产品的消费间接拉动了我国大豆的进口.除此,由于大豆属土地密集型农产品,利润率较低,在耕地资源短缺的条件下,我国应该生产那些劳动力密集、单位产量较高的农作物或收益较好的经济作物,进口土地密集型农作物.因此.进口大豆,出口大虾,符合全球资源的优化配置原则.     

Import competition,fast-track authority and U.S. policy toward China

Has the rise of China influenced U.S. legislation? China’s economic rise in the past 30 years has largely been driven by its exports of labor intensive products. Taking advantage of this supply shock in the United States and cross-district variation in the composition of industries, we investigate the potential role of Chinese imports in U.S. legislators’ decision on granting Fast-Track Authority to the president. Consistent with Conconi et al. (2012), our empirical analyses indicate that in districts with more industries that are exposed to Chinese import competition, legislators are less likely to give up the power to amend international trade agreements. Interestingly, Chinese imports may distort the view of constituents toward China which render legislators in districts subject to large Chinese import competition to take an affirmative position on foreign policy that may hurt China.     

Economic determinants of Soviet foreign trade with Eastern Europe

Using a cross-sectionally correlated and time-wise autoregressive pooling procedure, we have obtained long-run estimates of export and import elasticities of Soviet-East European bilateral trade with respect to supply, demand and trade resistance factors. Our results indicate that Soviet exports to East Europe during 1963–1973 was, for most product groups, determined by demand conditions found in the East European partner countries while Soviet imports from Eastern Europe, for the same period, was for most product groups determined by East European supplies.     

Aggregated and disaggregated import demand in China: An empirical study

This paper re-estimates both the aggregated and disaggregated import demand functions for China. We consider six groups of goods for the disaggregated imports based on the Standard International Trade Classification (SITC). The empirical findings from the dynamic ordinary least squares and autoregressive distributed lag regressions indicate that there are positive effects of the domestic income on imports. Second, contrary to theory but in line with previous studies, we obtain negative coefficients for the real effective exchange rate—a real appreciation in the Renminbi (RMB) would reduce import demand. Third, the period of the great global recession is negatively associated with the import demand in China. Fourth, the perception of tail risk negatively affects demand for the aggregated imports and five of six groups for the disaggregated imports. Fifth, the exchange rate reform had a positive impact on the aggregated imports, but our estimations report mixed results for the disaggregated imports. Finally, our results indicate that there is no aggregation bias for import demand in China.     

The aggregate import equation: Price homogeneity and monetary effects

The theoretical and empirical assumptions implied by conventional import equations are identified and tested for the US and UK. The demand for imports is found to respond much more strongly to changes in domestic rather than foreign prices. The elasticity with respect to income estimated by traditional functions is shown to be upward biased. Finally, a direct link between the money supply and imports is established, with consequences for all import elasticities.     

Can China’s meat imports be sustainable? A case study of mad cow disease

Rising demand and constrained domestic production have challenged the meat consumption in China. To fill the gap between domestic demand and supply, China imports an increasing volume of meat products from the international market. However, outbreaks of animal diseases can jeopardize China’s ability to meet its need for consumable meat. This article investigates the impact of animal disease outbreaks on the sustainability of China’s meat imports by using the episode of bovine spongiform encephalopathy in the United States in 2003 as a case study. Our results show that China’s meat imports are becoming more diversified and sustainable. The outbreak did have significant negative impacts on beef imports from the United States. During the epidemic, not only was China able to increase beef imports from other major exporters, but it also increased imports of other animal products such as edible offal and pork. Our findings indicate that international trade can serve as a reliable source to meet China’s soaring meat consumption.     

How Elastic is East Asian Demand for Consumption Goods?

This paper investigates import demand in East Asia. Estimating exchange rate elasticities for countries in the region is difficult because many imports are used to produce goods for re‐export. An exchange rate appreciation that reduces East Asian exports will also reduce the demand for imported inputs that are used to produce exports. To correct for this bias this paper examines consumption imports, since these goods are intended primarily for the domestic market. Results from several specifications indicate that currency appreciations and increases in income in East Asian countries would significantly increase imports into the region.     

Differences in exchange rate pass-through in the euro area

This paper focuses on the pass-through of exchange rate changes into the prices of imports made by euro area countries originating outside the area. Using data on import unit values for 13 different product categories for each country, we estimate industry-specific rates of pass-through across and within countries for all euro members. In the short-run, pass-through rates differ across industries and countries and are less than one. In the long-run neither full pass-through nor equality of pass-through rates across industries and countries can be rejected. Differences exist across euro area countries in the degree that a common exchange rate movement gets transmitted into consumer prices and costs of production indices. Most of these differences in transmission rates are due to the distinct degree of openness of each country to non-euro area imports rather than to the heterogeneity in the structure of imports.

European Integration and Production in the French Economy

Effects of greater European integration on the French economy are explored with an aggregate cost function. Input direct price elasticities are inelastic, but greatest (absolute value) for capital and lowest for imports. Cross-price elasticities suggest inputs are substitutes and are higher for domestic inputs than domestic input and imports pairs. As trade restrictions fall, effects on domestic input demand may increase as substitution elasticities rise. Inverse output supply price elasticities indicate domestic input prices are relatively important factors affecting consumption goods prices and import prices more important for investment goods. Thus, import price decreases may stimulate investment and growth. (JEL F14 , O10 , O12 )     

Food Protection for Sale*

This article tests the Protection for Sale (PFS) model using detailed data from US food‐processing industries under alternative import‐demand specifications. All empirical results support the PFS model predictions and previous empirical work qualitatively. However, a surprising result is that we obtain weights between 2.6 and 3.6 for domestic welfare using import slopes or elasticities derived from domestic demand and supply functions. In contrast, results based on directly specified import demands (including the Armington model) yield the usual, unrealistically large estimates for the domestic welfare weight. We contend that this empirical paradox arises mainly because the explanatory variables tend to be extremely large for industries with low import ratios and/or low import elasticities (or slopes) resulting from relatively volatile import prices. The results with derived import parameters point to a much stronger role of campaign contributions within the PFS model than previously found.     

Optimal Policy Intervention To Reduce Import Dependence

Should a country wish to reduce its dependence on imports of a certain commodity, an import tariff is typically recommended as the first-best (lowest-cost) policy instrument for achieving this non-economic objective. This note shows that while this is correct if the objective is to restrain imports to a certain quantity, it is not correct if the target is to reduce imports to a certain percentage of domestic consumption. In the latter case, a tariff-funded subsidy to producers is also required, the extent of which is larger the smaller the domestic price elasticities of demand and supply for the commodity.

TRADE CREATION AND DIVERSION EFFECTS OF THE U.S.-CANADIAN FREE TRADE AGREEMENT

This study empirically estimates and evaluates the economic benefits of the U.S. and Canadian Free Trade Agreement (FTA). Most past studies rely on aggregate data. The analysis here emphasizes the trade effects of removing tariff and nontariff barriers on each commodity group classified by the Standard International Trade Classification. Estimating the amount of trade expansion under FTA for both countries involves using the import demand elasticities from a dynamic demand model. Results show that U.S. imports from Canada are more sensitive to domestic, import, and world prices than are Canadian imports from the United States. U.S. imports from Canada would increase roughly £3.257 billion compared to the £2.432 billion increase for Canadian imports from the United States .     

Trends in Disaggregated Import and Export Prices in Europe: Implications for the Trade and Wages Debate

We consider carefully the evidence from traded prices (as proxied by unit values) concerning the transmission of the effects of globalisation to domestic labour markets. Using standard index number techniques we decompose changes in sectoral import and export unit values into movements due to changes in pure prices of the initial bundle of goods imported or exported and changes due to upgrading of that bundle. Looking at the imports of selected European countries of textiles, clothing and footwear relative to engineering products we find evidence of strongly falling pure prices of the unskilled intensive products relative to the skilled products in the 1980s. This reinforces the view that import prices can capture the impact of globalisation in terms of falling relative prices for products produced with the intensive use of unskilled labour. However, the trends are not common across all the unskilled sectors; footwear is clearly an exception. In the absence of detailed domestic data, we look for reactions by domestic firms to increased import competition in movements in the price and composition of exports. We find evidence of stiff price competition from imports being associated with similar movements in export prices and no support for the view that import competition from low–wage countries has led to upgrading of the quality of exports.
