Credit constraints and margins of import: first evidence for German manufacturing enterprises

This study uses tailor-made enterprise-level data for 2008–2010 from various sources for firms from manufacturing industries to test for the link between credit constraints, measured by a credit rating score provided by a leading credit rating agency, and imports in Germany for the first time. We find empirical evidence that a better credit rating score is positively related to extensive margins of import – firms with a better score have a higher probability to import, they import more goods and they source from more countries of origin. The intensive margin of imports – the share of imports in total sales – is found not to be related to credit constraints.     

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.     

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.     

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.

COMPETITIVE NEED LIMITS AND THE U.S. GENERALIZED SYSTEM OF PREFERENCE

The United States uses competitive need limits to deny Generalized System of Preferences (GSP) treatment of imports from developing countries. The analysis here estimates in two ways the effect of competitive need limits on GSP imports. First, it uses ex post trade data to determine the effect on import values and shares. Second, it combines an ex ante model with trade and elasticity data to estimate the effect of competitive need limits. Results indicate that competitive need limits reduce affected imports by 10 to 17%. Benefits from this import reduction accrue almost exclusively to U.S. import competing firms.     

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.     

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.     

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.     

自主研发、技术引进与生产率——基于中国地区工业的实证研究

本文运用1996—2003年中国地区工业面板数据研究了自主研发、国外技术引进和国内技术引进对生产率的影响。在生产函数理论基础上,通过核算自主研发存量和国内外技术引进存量,运用一阶差分法和固定效应法,本文发现自主研发和国外技术引进对生产率有显著促进作用,但国内技术引进对生产率并没有显著影响。研究还发现,我国自主研发的吸收能力较低,阻碍了对引进技术的学习和消化,进而影响了生产率增长。自主研发、国外技术引进对生产率的影响也表现出明显的地区差异:自主研发只对东部和中部地区的生产率有显著正效应,而国外技术引进只对西部地区的生产率有显著正效应。各个地区不同的技术发展水平和创新能力基础可能是造成该现象的主要原因。     

我国通货膨胀、FDI及进出口的关联性研究——基于VAR模型的实证分析

我国的通货膨胀水平与FDI、进出口具有协整关系。其中出口、FDI对通货膨胀的影响微弱,而进口对通货膨胀的贡献率较高,达10%左右。VAR模型的方差分解表明,在通货膨胀、FDI、进口和出口四个变量中,引起CPI持续变化的是CPI本身,即我国的通货膨胀有明显的自循环特征。研究表明,我国并不存在明显的输入型通货膨胀,相反,进口有利于抑制我国的通胀水平。     

Use Tables for Imported Goods and Valuation Matrices for Trade Margins—an Integrated Approach for the Compilation of the Belgian 1995 Input–Output Tables

This paper describes the compilation of the use table for imported goods and the valuation matrix of trade margins for Belgium in 1995. It introduces the methodological novelty of integrating the compilation of both tables and systematically exploiting the fact that large import and export flows do not generate trade margins. This is notably the case for direct imports for intermediate consumption or investment by non-traders, and direct exports by producers. For identifying these trade flows, extensive use was made of intrastat and extrastat data. The results are compared with those of a proportional distribution of imports and trade margins. Many statistical offices resort to the latter approach because of a lack of survey data on the destination of trade margins and imports. We demonstrate that the integrated approach can improve the quality of both the import matrix and the valuation matrix for trade margins, while using only existing data sources.     

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]     

The effects of government expenditure on imports in the Eurozone reconsidered: evidence from panel data

This study examines the impact of government expenditure on imports. The empirical analysis is based on annual data of the euro area countries for the period 1995–2015. We employ econometric methods that mitigate heterogeneity and cross-sectional dependence. We provide empirical indications that the components of expenditure have different impact on imports demand. The findings of this study indicate that the import context of government expenditure is lower than the import context of others expenditure components. Finally, we find that an increase in government expenditure leads to an increase in imports; this implies that, ceteris paribus that it can lead to a deterioration of the trade balance.     

EXCHANGE RATE PROBLEMS IN NATIONAL ACCOUNTING OF DEVELOPING COUNTRIES*

Developing countries which typically have import surpluses and inflationary pressures because of insufficient savings are prone to use indirect taxes on imports (Tm) and subsidization of exports (Sx) in order to prevent deterioration of the balance of trade. If these substitutes for devaluation are included in the net indirect tax component of product at current market prices (Ym) the import surplus is likely to be understated, and Ym upward biased. This distortion will be avoided if imports and exports are measured at effective exchange rates (ER), that is, at official rates (OR) plus Tm and Sx respectively, and if (Tm - Sx) is deducted from the net indirect tax component of Ym. Only in this manner become imports and exports consistent with the other uses and resources at market prices and can be articulated with them. At base-year prices the volume index of product at OR diverges from that of ER to the degree that the composition of imports and exports in regard to tax and subsidy rates computed ad valorem significantly changes. Such a case is similar to that of the price indexes of imports and exports moving in diverging proportions: the trade balance at base-year prices will differ from that at current prices. The resulting discrepancies in national accounts have led to proposals of deflating, for example, exports by the price index of imports. Suchlike approaches are incompatible with the principle of national accounting that prices are supposed already to measure substitution values. Deflating exports by import prices means reintroducing substitution values, as does, for example, deflation of incomes by a consumer price index. Correspondingly, since the trade balance at ER conceptually expresses the value of imports at domestic market prices as compared to the corresponding domestic market value of exports, and if at ER the trade balance diverges from that at OR, the former balance has an important meaning (as has the trade balance at base-year prices as compared to that at current prices) and the resulting discrepancy between the two measures should not be removed merely for the sake of accounting smoothness. In contrast to the market price approach, the measurement of product at base-year factor cost is indifferent to the measurement of the trade balance at ER and at OR. It is, therefore, proposed in countries in which part of import taxation and export subsidization substitutes for devaluation, to record imports and exports in the national accounts at effective exchange rates, and to correct the net indirect tax component of product correspondingly. Imports and exports at official exchange rates should be shown within the balance of payments, and the latter separately as a memorandum item.     

Imports and the structure of retail markets

Abstract We construct a model of trade with heterogeneous retailers to examine the effects of trade liberalization on retail market structure, imports and social welfare. We are especially interested in investigating the transmission of lower import prices into consumer prices and the effects of retail market regulation. The paper shows that changes in import prices may have large effects on consumer prices and import volumes when changes in retail market structure are taken into account, and that restrictions on retailing, as they occur in several countries, may significantly alter this transmission mechanism by reducing imports and raising consumer prices.     

The Impact of Chinese Exports on Global Import Prices*

This paper evaluates the evidence bearing on the question of whether China's buoyant export growth has led to significant changes in the import prices, and thus inflation performance, of its trading partners. This evidence suggests that the impact of Chinese exports on global import prices has been, while non‐ negligible, fairly modest. We identify a statistically significant effect of US imports from China on US import prices, but given the size of this effect and the relatively low share of imports in US GDP, the ultimate impact on US consumer prices has likely been quite small. Moreover, imports from China had little apparent effect on US producer prices. Finally, using a multi‐country database of trade transactions, we estimate that, since 1993, Chinese exports lowered annual import inflation in a large set of economies by 0.25 percentage point or less on average.     

Quantifying South Africa's crude oil import risk: A multi-criteria portfolio model

A major consequence of South Africa's strong economic growth since the democratic dispensation of 1994 is the rapid increase in domestic demand for oil energy. With small amounts of proven oil reserves, the rise in oil demand as an energy source has resulted in South Africa's growing dependence on external sources for its domestic crude oil needs. High oil prices, instability in major oil producing regions and the rise in ‘oil-nationalism’ are major concerns for the security of South Africa's oil supplies. Accordingly, a comprehensive understanding of oil import security risks can serve as a vital guide in formulating any energy policy framework(s) aimed at alleviating the impact of such risks. This study utilises portfolio theory and develops an empirical framework to provide quantitative measures of systematic and specific risks of South Africa's crude oil imports over the period 1994 to 2007. The paper examines the relationship between supply sources diversification and oil energy security risks, and provides an objective evaluation of different import adjustment strategies on South Africa's total crude oil import risks. The results show that a policy of having constant monthly imports from each supply region reduces the specific and systematic risks of the oil import portfolio by an average rate of 71% and 2.9% respectively. Significant reduction in specific risks of South Africa's oil imports is achieved if imports from risky regions (mainly the Middle East) can be diversified to relatively less risky regions of Europe and North America.     

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 .     

IMPORT FORECASTS FOR INPUT-OUTPUT MODELS*

The paper presents forecasting models for (1) the share of competitive imports in the total demand for a commodity group and (2) the level of demand for competitive imports of a commodity group. The two forecasting models are used, respectively, with (1) input-output models which incorporate market share parameters as one vector of coefficients and (2) input-output models which assume imports have been determined autonomously. It is shown that these two types of input-output models can be made workable by prefixing one or other of the import forecasting models to the input-output model. Tests are made of the forecasting ability of the combined models.
