Estimating the import demand function for China

This paper estimates the import demand elasticity for China using three fully efficient cointegrating regressions and the autoregressive distributed lag (ARDL) method. This paper is the first to accommodate the perception of global risk in an investigation of the information transmission mechanism between the relationship import demand and its determinants in China. The empirical results show that real imports are cointegrated with domestic economic activity, real effective exchange rate, and the perception of global risk. Domestic income is found to have a significantly positive effect on imports. Contrary to theory, the real effective exchange rate carries negative coefficients, which suggests that a decrease in external competitiveness (appreciation) will decrease the level of imports in the case of China. One of the reasons for this may be the tied anti-dumping duty on some import items. Since the perception of global risk adversely affects China's aggregated imports, policy-makers should consider the degree to which the perception of global risk affects the implementation of trade policies.     

A dynamic disaggregated model of finnish imports of goods

The purpose of this paper is to test and estimate dynamic aggregated and disaggregated models of import demand with quarterly Finnish data. The main conclusions are that the log-linear functional form is preferable to the linear form and that there is empirical support in favor of estimation of import demand models in a disaggregated framework. On the whole, adjustment of Finnish imports of goods is relatively fast.     

Foreign exchange reserves and import demand in a developing economy: the case of Pakistan

Conventional specifications of import demand in LDCs have commonly been plagued by implausible and unstable parameter estimates. This paper shows the importance of imposing long‐run income homogeneity and of including foreign exchange reserves when estimating import demand function for an LDC. Using several cointegration techniques, it is shown that there is one linear relationship among real imports, real income, relative import prices and real foreign exchange reserves. In addition, by employing stability tests for cointegrated systems by Hansen (1992a), the paper shows that only when foreign exchange reserves and long‐run unit‐income homogeneity are accounted for does a constant parameter, long‐run equilibrium relation emerge for Pakistan. Also, the ensuing short‐run dynamic model is constant and data‐coherent. Finally, the study provides information on the speed of adjustment to equilibrium and the median and mean time lags of adjustments of real imports to changes in their determinants. The results indicate a quick response of real imports to changes in their determinants.     

Quantitative restrictions and Indian imports

Many governments in LDCs tend 3o rely heavily on import control for achieving adjustments in the balance of payments. The empirical analysis of imports of these countries has failed to address the issue of quantitative restrictions satisfactorily. In this paper, a set of disaggregated import demand equations are specified which attempt to capture the government's decision regarding quota restrictions. The model postulates that the overall level of imports is determined by expected foreign exchange availability while the composition of imports (once the level has been decided) is based on political and economic priorities and on relative prices.     

Import dynamics and demands for protection

What kinds of changes in foreign competition lead domestic industries to seek import protection? To address this question, we use detailed monthly US import data to investigate changes in import composition during a 24‐month window immediately preceding the filing of a petition for import protection. A decomposition methodology allows a comparison of imports from two groups of countries supplying the same product: those that are named in the petition and those that are not. The same decomposition can be applied to products quite similar to the imports in question, but not subject to a petition. The results suggest that industries typically seek protection when faced with a specific pattern of shocks. First, a persistent positive relative supply shock favours imports from named countries. Second, a negative demand shock hits imports from all sources just prior to domestic industries’ petition for protection. The relative supply shock is a broad one; it applies both to named commodities and to the comparison product group. The import demand shock, by contrast, is narrow, hitting only named products. This negative import demand shock appears to be a key event in the run‐up to the filing of a petition. This latter shock has been missed by previous studies using more aggregated data.     

人民币升值能解决美国对华贸易赤字吗?——基于1994～2005年间月度数据的贸易弹性分析

文章以1994年1月到2005年3月的月度数据为样本,用ARDL框架下的协整方法,对中美贸易的收入弹性和实际汇率弹性进行了经验分析。分析后发现:第一,我国对美进出口的收入弹性都是显著的,并且我国对美国出口的收入弹性约为我国从美进口的收入弹性的6倍,但是我国对美进口和出口的实际汇率弹性都是不显著的。因此,文章认为人民币汇率对中美贸易没有显著影响,人民币汇率升值将无法改善美国的对华贸易收支。     

European Integration and Manufactures Import Demand: An Empirical Investigation of Ten European Countries

This paper studies import demand in ten European countries over the period 1970–95, and our objective is to investigate whether the process of European integration has affected imports. We provide evidence for parametric change in traditional import demand equations, suggesting that important variables or structural factors are missing from the long-run equations. We present equations based on new trade theory, where effects of technology and foreign direct investment are present. Once we include these there is little evidence that the creation of the Single Market has directly increased aggregated imports in European countries.     

Exchange rate volatility and United Kingdom trade: evidence from Canada,Japan and New Zealand

This paper investigates the influence of exchange rate volatility on the real imports of the United Kingdom from Canada, Japan and New Zealand during the period 1980–2003. The Johansen multivariate cointegration method and the constrained error correction (general-to-specific) method are applied to study the relationship between real imports and its determinants (including exchange rate volatility). Conditional variance from the GARCH(1,1) model is applied as exchange rate volatility. Both nominal and real exchange rates are employed in the empirical study. Results indicate a significant effect of the exchange rate volatility on real imports. These exchange rate volatility effects are mostly positive. The author thanks an anonymous referee, the editor and Myles Wallace for several useful comments and suggestions. Any remaining errors and omissions are the author’s responsibility alone.     

Can China Feed its People into the Next Millennium? Projections for China's grain supply and demand to 2010

Econometric models of grain supply and demand which incorporate the effects of policy interventions and institutional changes are used as the basis for projecting grain balances in China to 2010. The paper outlines key assumptions about future changes in grain policies and other important explanatory variables in the models. On the supply side, projections are made for grain sown area, grain yield and total grain output. Future grain demand is disaggregated into four categories, human food, animal feed, industrial uses and seed grain, each incorporating high, medium and low demand growth scenarios. A grain balance sheet is constructed for 2010 which shows a ‘most probable’ import requirement of about 32 million tones—a 10 million tones increase over the actual 1995 level. Thus, net grain imports will increase substantially but China is unlikely to become an importer on a massive scale.     

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.     

The exchange rate pass-through into import prices: the case of Japanese meat imports

Japan is a traditional net importer of food products in general and meat products in particular. Japanese meat imports come from a few countries thus making Japan potentially very sensitive to the swings in one or a few bilateral exchange rates. One of the key contributions of this article is the use of commodity (meats in this case) imports weighted exchange rates in the analysis. The standard practice in previous international agricultural trade studies related to either exchange rate pass-through or pricing to market was to use the aggregate trade weighted exchange rates usually provided by the Central Bank authorities or sources. Beef and poultry import prices indicate partial exchange rate pass-through while import prices of pork indicate zero exchange rate pass-through, primarily due to gate price policy system applied to pork imports. In terms of competitiveness, these results suggest relatively more competitive markets among poultry importing firms, somewhat competitive markets among beef importing firms, while competitiveness of pork importing firms could not be assessed due to existing import policies.     

Does exchange-rate uncertainty matter in the Malaysia–E.U. bilateral trade? An industry level investigation

Due to ambiguity in the past literature, researchers have examined exchange rate volatility effect on trade using disaggregated data in recent years. Previous research has focused more on aggregated data having aggregation bias which has led to unnecessarily over-generalized findings. This study investigates the impact of exchange rate volatility on the Malaysian bilateral trade flows with European Union using industry level data. Our empirical findings, based on auto-regressive distributed lag framework, suggest that many import and export industries experience exchange rate volatility influence in the short run, while a very small number of industries show this effect in the long run. Moreover, the adverse impact of financial crisis (2007–2008) is more prevalent on import industries compared to export industries.     

进口贸易是否抑制了技术进步——状态空间模型的再检验

本文基于周方的“增长函数”,并借鉴“广义索罗余值”思想对中国技术进步水平和速率进行重新测度。在此基础上构建状态空间模型并利用卡尔曼滤波,实证分析进口贸易对技术进步和技术进步速率的影响。本文研究表明：第一,中国的技术水平虽然整体保持增长,但是速率波动很大,表明技术进步趋势尚不稳定;第二,进口贸易对技术进步呈现显著负向影响,改革开放虽然减轻了影响程度,却没有改变影响方向。可见进口贸易在一定程度上抑制了技术进步,但是进口贸易对技术进步速率的影响依然显著为正。     

Exchange rate volatility and exports: a firm-level analysis

The relationship between real exports and exchange rate volatility is investigated using panel data analysis at the firm level. Results indicate that there is no negative or positive relationship between volatility and real exports. In addition, firm size and level of international activity do not influence the size and significance of the volatility effect on exports. However, there is some evidence that firms use import revenue to lower their exchange rate exposure.     

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.     

Cyclical and political influences on the size distribution of income in the US (1959–1989)

This study addresses the question of whether exchange rate pass-through into the import price is symmetric between appreciation and depreciation of the home currency. The dramatic increase of the dollar in the early 1980s and the subsequent decline provided a necessary setting for testing whether there was a structural change in the exchange rate pass-through. Examining import price data for 98 disaggregated SIC industries in the US manufacturing sector and the US import price for all commodities, mixed evidence is found regarding the stability of exchange rate pass-through.     

Time-varying regional integration of stock markets in Southeast Europe

In an attempt to assess the impact of currency depreciation on the trade balance, recent studies are employing disaggregated trade data to avoid aggregation bias. However, since import and export prices are not available at disaggregated level, recent studies are using export and import values rather than their volumes so that they can establish direct relation between inpayments and the exchange rate as well as between outpayments and the exchange rate. This study explores the experience of Malaysia. Bilateral inpayments and outpayments models are estimated between Malaysia and her 14 trading partners using quarterly data and bound testing approach to cointegration. The results show that while real depreciation of the ringgit has short-run effects, in the long-run it increases Malaysia's inpayments from only five trading partners.     

Real Exchange Rate Volatility and Imports of Intermediate Inputs: A Microeconometric Analysis of Manufacturing Plants

This paper uses plant‐level data from the manufacturing sector of Chile for the period 1995–2007 to examine the effect of real exchange rate (RER) volatility on imports of intermediate inputs at the micro level. Using input–output tables, we construct sector‐level RERs relevant for input import decisions and find that increases in the RER and its volatility reduce the fraction of imported intermediate inputs used by plants, while plants' probability of importing is not affected. Thus, fluctuations in the RER affect the intensive margin of imports (the amount of inputs imported) but not the extensive margin (the decision to import).     

Imports and growth in China

In this paper, we analyze the role played by imports and investment on labor productivity and output in China from 1964 to 2004. In doing so, our analysis focuses on the role of technological progress incorporated into the Chinese economy through capital accumulation and imports, which could be a cause of significant technology transfer from abroad that facilitated industrialization and rapid growth in China. However, as we know that there could be other factors influencing economic development, we have also considered the role played by domestic innovation activities, competitiveness and foreign economic conditions. We focus on examining the short- and long-run effects of the considered variables as well as the direction of their causality. In addition, we investigate the role played by the exchange rate on growth and discuss some policy implications of this effect on the current debate on the appreciation of the Yuan. The empirical results provide evidence that both imports and investment encourage output and labor productivity in the long run, but neither investment causes imports nor imports cause investment. Moreover, we found that during the period considered the real exchange rate influenced output, but not productivity. These findings provide interesting insights on the future Chinese economic policy.     

Relative Responsiveness of Trade Flows to a Change in Prices and Exchange Rate

A country can restrict her imports by imposing tariffs and stimulating her exports by providing subsidies. The same goal could be achieved through devaluation. One policy question that we face is the time it takes for either policy to affect the trade flows. We investigate here the relative responsiveness of the trade flows to a change in relative prices versus to a change in exchange rate. After estimating an error-correction version of import and export demand functions for nine industrial countries, unlike earlier studies that employed non-stationary data, our findings indicate that there is no specific answer and trade flows of different countries react differently.
