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).     

Bailing outsourcing

In a model of organizational choice, this paper shows that in face of an increasingly expected bailout from the government, outsourcing input production to an offshore location is more likely an optimal choice for a firm. Such a response is consistent with the three trends in the US manufacturing sector after the crisis: (a) employment keeps declining; (b) massive layoffs have not stopped; and (c) imported intermediate inputs have been gaining importance.     

Exchange rate pass-through and product heterogeneity: Does quality matter on the import side?

This paper investigates theoretically and empirically the heterogeneous response of exporters to real exchange rate fluctuations due to the quality of imported inputs and exported output. We develop a model where the production of high-quality products requires high-quality inputs sold in monopolistically competitive foreign markets. The model predicts that exporters using imported inputs have low exchange rate pass-through, but this effect is weaker for firms shipping high-quality goods. This is due to the heterogeneous price adjustments of foreign suppliers selling inputs of different quality. We test the predictions of the model using Italian firm-level trade data for the period 2000–2006. The empirical analysis shows that the imports of intermediates have a significantly weaker effect in reducing the exchange rate pass-through into the export price of high-quality varieties. By showing that the import price of high-quality inputs is less sensitive to exchange rate variations, we provide evidence supporting the theoretical hypothesis that the pricing power of input suppliers weakens the import channel.     

Heterogeneity of imported intermediate inputs and labour: evidence from India’s input tariff liberalization

This article explores whether the nature of imports matters when examining the effects of trade on plant-level labour outcomes. Previous literature that examines this question mainly considers imported intermediate inputs as a homogenous group and is unable to reach a consensus on the effects of input tariff liberalization on employment and wages of skilled and unskilled workers. Exploiting detailed product-level information available on intermediate inputs from plant-level data for the Indian manufacturing sector, I distinguish between plants that import mainly for quality considerations as opposed to plants that seek imports as cheaper alternatives to domestic inputs. I find that strong complementarities exist between skilled workers and imported inputs for plants importing high-quality inputs. For plants importing intermediate inputs mainly as a cost-cutting strategy, input tariff liberalization leads to an increase in employment of both skilled and unskilled workers, but a decline in skill composition. This can best be explained as a strategy that achieves economies of scale. On average, as input tariffs liberalize, importing plants employ more workers and pay higher wages than non-importing plants.     

ESTIMATION ERROR IN SECTORAL EMPLOYMENT REQUIREMENTS IN THE ABSENCE OF A DOMESTIC COEFFICIENTS MATRIX IN THE INPUT-OUTPUT ANALYSIS

The objective of the paper is to develop various estimation methods for allocating imports according to their end-use and to make use of the derived domestic transactions for the estimation of gross domestic output and employment by sectors. The standard design in the construction of input-output tables is to provide imports of a sector in the form of a column. These imports are not allocated according to their final use and therefore, total intermediate inputs consist of both domestic and imported inputs. The input-output tables for 12 European countries distinguish three types of transactions: (a) domestically produced inputs; (b) imported inputs; and (c) total inputs. We have made use of these tables assuming that the information on import allocation by end-use and domestically produced and imported inputs separately are not available. The allocations of imports are made under various assumptions and a comparison is made of employment based on artificially generated domestic coefficients with employment based on actual coefficients. The sectors are ranked on the basis of both sets of results. In addition, the ratio of indirect to direct employment for the estimators and actual is derived. The sectors are ranked and the rank correlations between alternative estimators and actual are calculated. Although the ratios differ markedly from method to method, the ranks do not alter.     

Measuring Vertical Specialization: The Case of China

The explosive growth of Chinese trade may be due to international production fragmentation, but few have assessed these phenomena together, in part, because it is difficult to measure the vertical specialization (VS) of China's trade. Unique features of China's processing trade cause both identification of imported inputs and their allocation across sectors to vary by trade regime. This paper estimates the VS of Chinese merchandise exports, addressing these two challenges. A new method to identify Chinese imported inputs is developed, and used to calculate VS by sector and destination. VS estimates based on the official Chinese input–output table are contrasted with those based on a split table, capturing processing and normal exports separately. Last, the paper tests whether Chinese “export sophistication” can be explained by VS.     

On the Terms of Trade and Sectoral Reallocations

A commonly held view is that a small open economy adjusts to a negative external shock by switching both expenditure and resources toward the domestic traded goods sector. We show that, when both labor and imported inputs are used as factors of production, the average labor intensity in the nontraded sector may increase substantially with a decline in the terms of trade. This can lead to an internal transfer of labor into the nontraded sector, and an improvement in the trade balance even with a decline in traded sector output. This result depends on a combination of a high elasticity of substitution across nontraded varieties and large differences in labor intensities in the production of nontraded varieties. Our analysis suggests that intersectoral labor flows are not necessarily a good measure of an economy's flexibility, and that intersectoral resource reallocation and expenditure‐switching can move in opposite directions.     

Foreign trade and its impact on employment: The Mexican case

This paper discusses the relationship between foreign trade and employment in a small open economy, and carries out some empirical work using Mexican data. It is argued that employment multipliers are not stable if intermediate inputs are imported. Actual employment multipliers will be given by the relationship between effective demand and installed capacity in each sector, and will depend strongly on whether quotas or tariffs are in operation. It is also found that Mexican exports are capital intensive relative to its imports.     

Imported input varieties and product innovation: Evidence from five developing countries

We examine how access to imported intermediate inputs affects firm‐level product innovation in five developing counties. We combine trade data with survey data on innovation and develop a method to determine whether new inputs were essential for the product innovation. We find evidence that the number of newly imported varieties has a significant impact on product innovations that rely on new inputs and provide suggestive evidence that this effect comes from access to better quality imports. We extend our analysis to assess the consequences of the increase in the number of Chinese exporting firms on product innovation in developing countries.     

Exchange rates,market structure and price-cost margins: evidence from a developing country

This paper analyses the sensitivity of firm performance to exchange rate fluctuations. In a two-country world, consisting of a developing domestic country and a developed foreign country, we show that this sensitivity is closely related with market structure and the share of imported inputs in total cost. When the share of imported inputs is low, depreciation leads to an increase in price cost margin. This increase intensifies in more competitive industries. When the imported input share is high, the price cost margin may decrease as a result of depreciation, and this effect becomes pronounced in more competitive industries. The empirical test where we used 3-digit Turkish Manufacturing industry data support most of the findings of our model.     

On the relationship between intermediate input imports and export quality in China

This paper studies the connection between intermediate input imports and firms’ export quality using firm‐level data from 2000 to 2007. Our regression results show that intermediate input imports promote manufacturing firms’ export quality through ‘variety effects’ and ‘innovation effects’, though the effects are significantly different among firms with different characteristics, and the magnitude of these effects differs across import sources and the quality of imported intermediate inputs themselves. Moreover, we find that a good institutional environment is conducive to the strengthening of the positive influence of intermediate input imports on export quality. Furthermore, the dynamic decomposition demonstrates that the reallocation effect is the key force through which imported inputs boost industrial aggregate quality growth. Taken together, these results suggest that product upgrading facilitated by quality embedded in imported intermediate inputs, a good institutional environment and market share reallocation help Chinese firms to improve the quality of their export products.     

A structural VAR model of the Fiji Islands

A four-dimensional Structural Vector Auto-regression (SVAR) model is applied to investigate the implications of fuel imports and devaluation policy on Fiji's current account deficits and economic growth. The paper finds that short-term deterioration of the current account is partly due to higher fuel imports. The impulse response analysis shows that a standard deviation fall in Fiji's REER leads to a J-curve type response in the current account within a short period. Furthermore, fuel import demand and devaluations are found to have negative, but transitory, effect on economic growth.     

Energy prices,substitution, and optimal borrowing in the short run: An analysis of adjustment in oil importing developing countries

The paper discusses optimal short-term borrowing in response to an increase in the price of imported inputs. The rationale for borrowing lies in the increase in substitution possibilities in production (between imported and domestic inputs) and in consumption (between traded and non-traded goods) as the economy adjusts its structure to the new prices. A typology of LDCs and the oil price increases in the 70's are used to illustrate the results of the model, which are compared with the actual increase in borrowing during the period.     

The J-Curve

If a country with a balance of payments problem, that is, insufficient foreign exchange receipts to meet foreign exchange requirements, seeks to remedy the situation by currency devaluation, things may get worse before they get better. This so-called J-curve effect occurs if the domestic-currency prices of exports are sticky, whether because they are cost based or subject to longer term contracts, so that export prices in foreign currency fall. Until favourable volume effects outweigh the unfavourable price effect, the balance of payments deteriorates. Such a J-curve effect should be distinguished both from the longer term erosion of the beneficial effects of devaluation as domestic costs and the prices of non-tradables rise and from the apparent J-curve due to the ‘valuation effect’. If the current account is in deficit before devaluation, as will usually be the case, devaluation will widen the deficit in domestic currency because domestic-currency imports rise by a larger amount than exports. This is a pure valuation effect, of no significance for external balance. But it is liable to lead to unduly pessimistic judgements about the effectiveness of devaluation. In Australia during 1985–86, the current account deficit increased by $A3.5 billion, despite substantial depreciation of the $A. The main reason was a sharp deterioration in the terms of trade which is estimated to have worsened the current account by $A4.25 billion. Most of this was exogenous, though J-curve effects may have made a contribution. In addition, the valuation effect contributed a further, illusory, widening of the deficit, valued in domestic currency, by over $A1 billion. To avoid misleading inferences from the valuation effect, it is suggested that the balance of payments should, if possible, be presented in foreign currency.     

Bilateral J-curve between the UK vis-à-vis her major trading partners

Currency depreciation is said to worsen the trade balance first before resulting in an improvement, yielding a short-run pattern labelled the J-curve phenomenon. While early studies tested the J-curve by using aggregate trade data, a few recent studies have employed bilateral data, mostly between the US and her major trading partners. In this paper we extend the literature by considering the experience of the UK. We test the phenomenon between the UK and her twenty major trading partners by employing data over 1973Q1–2001Q3 period. In most instances, we find no support for the J-curve in the short-run. In the long run, only in five cases has the exchange rate had significant impact on the bilateral trade balance.     

The sectorial impact of commodity price shocks in Australia

This study reports that commodity price shocks predominantly affect the mining, construction and manufacturing industries in Australia. However, the financial and insurance sectors are found to be relatively unaffected. Mining industry profits and nominal output substantially increase in response to commodity price shocks. Construction output is also found to increase significantly, especially in response to a bulk commodity shock, as a result of increased demand for resource related construction. Increased demand for construction has a positive spillover effect to the parts of the manufacturing industry that supply the construction sector with intermediate inputs, such as the non-metallic mineral sub-industry. In contrast, other manufacturing sub-industries with only tenuous links to the resources sector such as textiles, clothing and other manufacturing, are relatively unresponsive to commodity price shocks.     

The US Economy from 1992 to 1998: Results from a Detailed CGE Model*

This paper describes historical and decomposition simulations undertaken for 1992–98 with a 500‐sector computable general equilibrium model of the US. The historical simulation provides estimates of movements in unobservable technology and preference variables. The decomposition simulation explains developments in the US economy in terms of movements in these variables and in observable exogenous variables such as tariffs. Both simulations produce many results. Here we use decomposition results to show that rapid growth in US international trade is explained mainly by technology changes that reduced costs in export‐orientated industries and increased inputs of commodities that are heavily imported.     

A comparison of specialisation gains from trade in in final and intermediate goods

This paper sets out a method for measuring and comparing the specialisation gains from trade in intermediate goods and final goods, based upon a vertically integrated sectors (VIS) modelling approach. The factor input requirements of domestic production to replace imported intermediates is compared with the factor requirements of the ‘compensating’ exports required to purchase the imports. This method is applied to the UK economy, using a 28 sector model and a breakdown of factor inputs into land, labour and capital. Estimates of net factor-usage or saving on individual factor (weighted for factor quality differences) and multi-factor bases are reported. The results indicate that trade in inputs and outputs was net labour-using, and net-capital and land-saving in 1979. The overall, or multi-factor, gain from trade in intermediates was greater than for trade in final goods in 1979, with overall resource savings of 3·01% and 1·73% respectively.     

Trade liberalization and Firms’ export performance in China: Theory and evidence

The focus of the literature surrounding trade liberalization has recently shifted from trade liberalization in imported final goods to studying the effects of trade liberalization in imported intermediate inputs. This emphasis fits very well the trade liberalization experience of China following its accession to the WTO in 2001. In this paper, we build a multi-sector heterogenous-firm model with trade in both intermediate goods and final goods, and we ask: How do final-goods producers respond to trade liberalization in imported inputs? Do they respond differently across sectors? How do firms respond differently to trade liberalization in imported-outputs instead? We separate the total effect of trade liberalization into those caused by inter-sectoral resource allocation (IRA) and by within-sector selection of firms according to productivity (which we call Melitz selection effect). It is the IRA effect that gives rise to differential impacts of trade liberalization in different sectors. These impacts include changes in the probability of entry into the export market, the fraction of firms that export and the share of export revenue. To test our hypotheses, we carry out both quantitative analysis and empirical analysis by using Chinese firm-level data. The results are consistent with our theoretical predictions.     

Skilled–unskilled wage inequality,product variety,public input and increasing returns: A static general equilibrium analysis

The paper develops a four sector small open economy model with two traded final good sectors, a public intermediate good producing sector and a nontraded good sector producing varieties of intermediate goods. There are three primary factors: capital, skilled labour and unskilled labour. Industrial sector producing a traded good uses capital, intermediate goods and skilled labour as inputs. Intermediate goods producing sector also uses capital and skilled labour. Public input producing sector and the agricultural sector producing the other traded good use capital and unskilled labour as inputs. It is shown that, if production technologies are the same for the agricultural sector and the public input producing sector and if the scale elasticity of output is very low, then an increase in capital stock (unskilled labour endowment) raises (lowers) the skilled–unskilled wage ratio. However, an increase in skilled labour endowment does not produce any unambiguous effect. On the other hand, an increase in the tax rate on industrial output and/or an increase in the price of the agricultural product, armed with the same set of assumptions, lowers the skilled–unskilled wage ratio.
