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.     

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.     

Globalization and inter‐industry wage differentials in China

This paper explores the relationship between globalization and inter‐industry wage differentials in China by using a two‐stage estimation approach. Taking advantage of a rich household survey dataset, this paper estimates the wage premium for each industry in the first stage conditional on individual worker and firm characteristics. Alternative measures of globalization are considered in the second stage: trade openness and capital openness. A disaggregation of trade into trade in final and intermediate goods shows that increases in import (export) shares of final goods reduce (increase) the wage premia significantly, whereas imports or exports of intermediate goods do not explain differences in industry wage premia. This finding is supported by stronger effects for final goods trade in coastal than noncoastal regions. Our results also show a positive relationship between capital openness and industrial wage premia, though this finding is less robust when potential endogeneity issues are allowed for.     

The Effects of Trade Liberalization in a Vertical Structure

Despite the importance of international trade on intermediate goods, the literature did not pay much attention to this aspect in determining the effects of trade liberalization in the presence of a labor union. We take up this issue here and show the effects of trade liberalization on the final goods and/or the intermediate goods, where the domestic firm pays unionized wage and imports intermediate goods. We show that trade liberalization on the intermediate goods (final goods) increases (decreases) the unionized wage, labor union's utility and domestic profit. Trade liberalization on both the final goods and intermediate goods may either increase or decrease the domestic unionized wage, labor union's utility and domestic profit depending on the input coefficients and the initial tariff levels. Our qualitative results are robust with respect to the intermediate goods market structure, the pricing strategy of the intermediate goods producers and the union's objective function.     

STRATEGIC EXPORT POLICY IN VERTICALLY RELATED MARKETS

This paper analyses how strategic export policies are affected by introducing an imperfectly competitive intermediate good into a Bertrand duopoly model with product differentiation, where a home and a foreign final‐good firm export to a third‐country market. It is shown that when the home and foreign markets for the intermediate good are segmented, the optimal export policy towards the final good is a tax. In contrast, under integrated markets, the optimal export intervention is a subsidy. Whether bilateral export intervention is welfare improving compared with free trade, depends on the degree of product differentiation between the home and foreign final goods.     

International trade and consumption network externalities

This paper studies the effects of trade liberalization in the presence of consumption network externalities. The framework is applicable to the choice of network products and sheds light on the debate on globalization and culture. In an extended Ricardian model of international trade the paper shows that: (i) trade is not Pareto inferior to autarky if the free trade equilibrium is unique; (ii) trade is not Pareto superior to autarky if both countries are diverse (network competition) under free trade, but can be if each country is homogenous (network monopoly); (iii) and when multiple free trade equilibria exist everybody in a country can lose from free trade if that country is homogenous under autarky. Consumers of imported network goods tend to gain, while consumers of exported network goods tend to lose from trade liberalization.     

South African trade policy mattersTrade performance and trade policy*

South African trade policy has exerted a major influence on the composition and aggregate growth of trade. In the Apartheid period, South Africa developed a comparative advantage in capital‐intensive primary and manufactured commodities partly because of its natural resource endowments, but also because the pattern of protection was particularly detrimental to exports of non‐commodity manufactured goods. By contrast, trade liberalization from 1990 not only increased imports, but by reducing both input costs and the relative profitability of domestic sales also boosted exports. This evidence suggests that additional trade liberalization and policies that afford South African firms access to inputs at world prices could well be part of the strategy to enhance export diversification.     

Growth and risk at the industry level: The real effects of financial liberalization

This paper analyzes the effects of financial liberalization on growth and volatility at the industry level in a large sample of countries. We estimate the impact of liberalization on production, employment, firm entry, capital accumulation, and productivity. In order to overcome omitted variables concerns, we employ a number of alternative difference-in-differences estimation strategies. We implement a propensity score matching algorithm to find a control group for each liberalizing country. In addition, we exploit variation in industry characteristics to obtain an alternative set of difference-in-differences estimates. Financial liberalization is found to have a positive effect on both growth and volatility of production across industries. The positive growth effect comes from increased entry of firms, higher capital accumulation, and an expansion in total employment. By contrast, we do not detect any effect of financial liberalization on measured productivity. Finally, the growth effects of liberalization appear temporary rather than permanent.     

Explaining Export Performance through Inputs: Evidence from Aggregated Cross‐country Firm‐level Data

Which trade barrier related to intermediate inputs forms a greater burden on the export performance of firms in developing countries? Using aggregated cross‐country firm‐level data covering 43 mostly developing economies, this paper estimates the marginal importance of the impact of various intermediate input trade cost barriers, namely tariffs, non‐tariff barriers (NTBs) and services barriers, on firms' export behavior. In a cross‐sectoral setting, this paper takes the firm's export performance in goods as a central focus to study the effects of these different trade barriers through the exporting firm's choice of use of intermediate inputs. The results show that the most significant trade barriers on inputs that impede export performance in developing countries are mainly NTBs and restrictions of services.     

Inequality,public good provision and the composition of trade

This paper investigates the effect of trade liberalization on the provision of public goods and shows that inequality also plays a vital role here. Public goods help enhance the productivity of firms, lower prices and raise profitability. The provision of public goods has different effects in closed and open economies. In an open economy, the impact of productive spending on increasing profit is stronger. Consequently, the opening up of the economy shifts the benefits of productive public goods from consumers to firms. As the median voters’, share of the firm’s profit rises, public goods become more appealing and flourish. Consequently, the manufacturing export is boosted by a rise in productivity.     

Determinants of vertical integration in export processing: Theory and evidence from China

This paper examines the determinants of vertical integration versus outsourcing in export processing, by exploiting the coexistence of two export processing regimes in China, which designate by law who owns and controls the imported components. Based on a variant of the Antràs-Helpman (2004) model, we show theoretically that control over imported components for assembly can affect firm integration decisions. Our empirical results show that when Chinese plants control the use of components, the export share of foreign-owned plants is positively correlated with the intensity of inputs provided by the headquarter (capital, skill, and R&D). These results are consistent with the property-rights theory of intra-firm trade. However, when foreign firms own and control the components, there is no evidence of a positive relationship between the intensity of headquarters' inputs and the prevalence of vertical integration. The results are consistent with our model that considers control over imported components as an alternative to asset ownership to alleviate hold-up by export-processing plants.     

Does input sector liberalization promote quality innovation and exports?

This paper examines the relationship between input sector liberalization and product quality innovation and export orientation by a LDC firm given the complementarity between high input quality and high product quality. We show that input sector liberalization per se may not induce quality innovation and outward orientation. In fact, in some situations, ceteris paribus input sector liberalization may increase the odds in favour of low-quality production. We show that total output sector liberalization, or surprisingly, a suitable degree of output sector protection is needed to be combined with input sector liberalization so that quality innovation is induced.     

Quota removal and firm-level offshoring: Theory and evidence

Recent literature indicates that offshoring can effectively increase firm productivity and improve product quality. Therefore, global value chains have increased in importance. In this paper, we investigate the impact of export growth on firm-level offshoring. Removal of the quota on textile and clothing products in importing countries boosts China's exports of quota-restricted products. This removal offers a quasi-natural experiment. Using a difference-in-differences approach, we find that export growth induced by the quota removal increases the extensive and intensive margins of firm-level offshoring. The impact is more pronounced on domestic firms and firms that are engaged in ordinary trade. Our findings suggest additional gains from trade liberalization: trade liberalization not only boosts exports, but also enhances firm productivity and product quality through encouraging firm-level offshoring.     

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.     

Are duty drawbacks on exports worth the hassle?

Abstract.  Many countries use duty drawbacks on exports, yet there is no consensus whether countries should embrace or abandon them. The answer depends on countries' development priorities and economic conditions. An increase in the drawback has a positive impact on export competitiveness, but the welfare effect is ambiguous. A welfare increase is more likely if the economy is small with high input tariffs, low initial drawback, low administrative costs and tariff leakages. In China duty drawback removal after meeting its WTO commitments improves welfare, but hurts economic efficiency, export competitiveness, and real incomes. Further liberalization can mitigate these negative effects.     

Trade in goods and services: Two sides of the same coin?

This study analyzes the interrelationship between goods and services in production and trade using the most recent input–output tables for all OECD countries. It first describes the role of services in production and trade in goods. Next, it proposes two models for analyzing the impact of services trade liberalization on industrial structure. The first captures the role of trade in tasks when countries have different technology i) in production of services; and ii) in organizing production. The latter has to the author's knowledge not been analyzed in the trade literature before. Countries with superior organizational technology (e.g. Japan) will strengthen their comparative advantage in manufacturing following trade liberalization in services. The second model explores the interrelationship between intermediate goods and services i) when they are substitutes; and ii) when they are complements. In both models the gains from trade liberalization is non-linear in trade costs. Going the last mile of liberalization has a much larger impact than taking the first steps.     

贸易自由化是如何影响我国出口产品质量的？*--基于贸易政策不确定性下降的视角

传统理论认为贸易自由化会促进出口产品的质量升级,但我国加入W TO后的情况却并非如此。文章基于贸易政策不确定性的视角,利用我国加入W TO前后美国对我国产品进行关税调整这一自然实验,通过倍差法分析了贸易自由化对我国出口产品质量的影响。研究表明：（1）在贸易自由化的过程中,贸易政策不确定性的下降会拉低我国的出口产品质量,且这一结论在改变质量测度方法、控制成本效应以及使用不同的产品属性、贸易对象和样本的情况下依然稳健;（2）贸易政策不确定性主要是通过广延边际上的质量调整降低了我国出口产品的总体质量,即在贸易政策不确定性下降幅度越大的产品中,有越多的生产低质量产品的企业进入出口市场;（3）在集约边际上,存续企业并未针对贸易政策不确定性的下降做出及时的产品质量调整,从而无法改变我国的产品质量在短期内下降的趋势。文章为我国如何在推行贸易自由化的同时实现出口产品质量升级提供了启示。     

Imports and TFP at the firm level: the role of absorptive capacity

This paper estimates the effect of the decision to import intermediate goods and capital equipment on Total Factor Productivity (TFP) at the firm level on a panel of Spanish firms (1991–2002). We use two alternative approaches. In the first, we estimate TFP and apply a diff‐in‐diff estimator with a control group constructed by propensity‐score matching. In the second, direct method, we estimate TFP with imported inputs as a state variable in one stage. Both approaches show that the effect of a firm's decision to source intermediates and capital equipment abroad on its TFP depends critically on its capacity to absorb technology, measured by the proportion of skilled labour.     

Measuring the Effects of Exchange Rate Changes on Investment in Australian Manufacturing Industry*

This paper examines the relationship between exchange rates and investment in Australian manufacturing between 1988 and 2001. The effects of exchange rates on investment are found to vary positively with the export share of sales and negatively with the share of imported inputs into production, with lower price‐over‐cost mark‐ups increasing the response. For Australian manufacturing, a 10 per cent real appreciation of the Australian dollar leads to an average 8.0 per cent decrease in total investment through the export share channel, and an average 3.8 per cent increase through the imported input share channel, with most of the response occurring through investment in equipment, plant and machinery.     

The Impact of Input and Output Tariffs on Firms' Productivity: Theory and Evidence

This paper studies the impact of trade liberalization on productivity. It shows that when intermediate inputs are not highly differentiated, lowering input tariffs leads to a rise in within‐firm productivity and wages, and lowering output tariffs has the opposite effect. When intermediate inputs are highly differentiated, the conclusions reverse. These predictions are supported by the data, given by the industrial survey from INEGI (Mexico's Insitituto Nacional de Estadistica Geografia e Informacion) in the period 1984–90. The paper yields estimates for the elasticity of substitution among intermediate inputs, which are useful in determining the direction of the impact of trade liberalization. These estimates can be used to assess the gains from trade liberalization.
