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.     

Fixed export cost heterogeneity, trade and welfare

Recent literature on the workhorse model of intra-industry trade has explored heterogeneous cost structures at the firm level. These approaches have proven to add realism and predictive power. This paper presents a new and simple heterogeneous-firms specification. We develop a symmetric two-country intra-industry trade model where firms are of two different marginal cost types and where fixed export costs are heterogeneous across firms. This model traces many of the stylized facts of international trade. However, we find that with heterogeneous fixed export costs there exists a positive bilateral tariff that maximizes national and world welfare.     

国外贸易保护措施对中国制造业出口的影响——来自企业层面的微观证据

当前,以贸易保护主义为主要特征的"逆全球化"思潮涌现,国外的贸易保护措施对中国制造业的出口增长构成严重的威胁.那么,这些贸易保护措施对中国制造业的出口到底产生了怎样的影响?其内在机制是什么?文章采用2009?2011年GTA数据库与中国海关统计数据库的合并数据,从企业这一微观层面定量识别国外贸易保护措施对中国制造业出口的实际影响.研究发现:(1)国外贸易保护措施的实施显著地降低了受影响企业的出口规模,贸易保护措施的数量每增加1次,受影响企业的出口将下降17%左右;贸易保护强度每增加1个单位,受影响企业的出口将下降52%左右.(2)从影响机制看,国外贸易保护措施对制造业出口的抑制效应是通过降低出口的数量和质量来实现的.(3)贸易融资对制造业出口的边际影响最大,而贸易救济措施是对制造业出口整体影响最大的贸易保护措施.(4)国外贸易保护措施对外资企业、同质产品以及中间品出口的抑制作用更明显.文章的研究结论既为理解贸易保护主义的危害提供了经验证据,也为中国在持续推动对外开放背景下如何应对贸易保护壁垒提供了决策依据.     

Estimating the impact of country‐level policy restrictions on services trade

Standard techniques used to estimate gravity equations, rely on bilateral variation to identify the effect of trade barriers on bilateral trade flows. In this paper, I develop a method that estimates the effects of country‐level variables on trade between countries in the presence of firm heterogeneity and country selection into trade, a natural extension of existing empirical models of international trade. I implement the method in services data, where available measures of trade policy provide information on the average level of regulations restricting entry into a country. The results suggest that policy barriers are important determinants of services trade flows.     

Service Deregulation,Competition, and the Performance of French and Italian Firms

This article reports estimates of the impact of service regulation reform on the productivity of French and Italian firms in retail, transports and professional services over the period 1998–2007. We implement a two‐stage least squares estimation: the first‐stage instruments mark‐ups, a financial measure of rents, with barriers to entry and the second stage estimates the impact of instrumented mark‐ups on total factor productivity (TFP), a real measure of firm efficiency. We find that entry barriers lower firm productivity by raising mark‐ups and rents. These estimates imply that, if French and Italian regulators had adopted the OECD best practices in terms of entry barriers, firms in these sectors would have increased their TFP level by five percentage points. We do not find any robust evidence of a non‐linear relation between mark‐up and productivity.     

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.     

A Welfare Ranking of Multilateral Reductions in Real and Tariff Trade Barriers when Firms are Heterogenous

Trade liberalization comes about through reductions in various types of trade barriers. This paper introduces, apart from the customary real trade costs (i.e. iceberg and fixed export costs), two revenue generating trade barriers (i.e. an ad valorem tariff and a trade license) into a standard heterogeneous‐firms‐trade model with Pareto distributed productivities. We derive analytical welfare rankings of all four liberalization channels for an equal effect on two openness measures, for any trade cost level and while all four barriers are simultaneously present, i.e. for any initial equilibrium. We show that when openness is measured at retail prices, not border prices, the welfare rankings are sensitive to the degree of efficiency in revenue redistribution, e.g. the share of tariff revenues wasted on rent‐seeking activities. As a result, multilateral tariff reductions can switch from the least to the most preferred mode of liberalization. Among the other three barriers we establish a universal welfare ranking for any strictly positive level of revenue redistribution and for either measure of openness.     

Strategic interoperability standards and trade taxes

In a two-country international trade framework, the paper considers the interplay between the governments' incentives for conducting traditional trade policies and their incentives for the policies toward compatibility between the products of the firms competing in the international market. The model assumes that one domestic and one foreign firm supply partially incompatible products for the home country market while consumers value both variety and a network externality. Motivated by the benefits of the network externality, the home government sets a standard requiring the foreign firm to guarantee a minimum level of compatibility between its own product and the product of the domestic rival. The paper analyzes the home country standard setting and import tariff policies as well as the incentives of the foreign country for imposing the export tax and conducting a policy which enhances the degree of compatibility between the rival products in the export market.

融资约束与企业出口行为:基于工业企业数据的经验研究

采用2000—2007年的3万多家工业企业数据,本文构造了包括内源融资、商业信贷以及企业信用特征等变量的企业融资约束综合指标。基于Heckman选择模型的经验研究表明,企业融资状况的改善不仅能提高企业出口的概率,而且对其出口规模也有重要影响。研究还发现融资状况改善对外资企业出口影响最显著;与国有企业相比,民营企业虽受到更严重的融资约束,但其出口表现并未更差。此外,融资状况改善对那些高外源融资依赖度行业的企业出口具有更明显的促进作用。     

“快速通关”贸易促进效应的实证分析

在低关税的时代,快速通关很可能是打破贸易壁垒,推动国际贸易发展的重要手段。文章从四个方面总结了快速通关对国际贸易的影响机制,并基于2008-2010年113个国家相互之间的出口数据,使用 Heckman两步选择模型进行了实证研究。结果显示,快速通关对贸易参与和贸易规模都有着显著的促进作用,从多个角度进行稳健性检验后,该结论依然成立。快速通关可以通过需求偏好效应、成本效应与全球化生产网络效应和遏制日益强化的非关税贸易壁垒的负面效应,使得多边谈判所形成的关税降低的效应得以真正发挥。此外,文章还发现,自由贸易协定的建立,提升了通关效率与边境管理的透明度,进而提高了国家间的贸易量。文章的研究结论对于理解目前中国建立自由贸易区以及实施在贸易谈判中主导快速通关的措施或建立条款,打破技术贸易壁垒具有重要的意义。     

Productivity effects of international outsourcing: evidence from plant-level data

Abstract.  We investigate the impact of international outsourcing on productivity using plant-level data for Irish manufacturing. Specifically, we distinguish the effect of outsourcing of materials from services inputs. Moreover, we examine whether the impact on productivity is different for plants being more embedded in international markets through exporting or being part of a multinational. Our results show robust evidence for positive effects from outsourcing of services inputs for exporters, either domestic or foreign owned. By contrast, we find no statistically significant evidence of an impact of international outsourcing of services on productivity for firms not operating on the export market.     

Estimating the effects of non‐discriminatory trade policies within structural gravity models

We propose a simple method to identify the effects of unilateral and non‐discriminatory trade policies on bilateral trade within a theoretically consistent empirical gravity model. Specifically, we argue that structural gravity estimations should be performed with data that include not only international trade flows but also intra‐national trade flows. The use of intra‐national sales allows identification of the effects of non‐discriminatory trade policies such as most favoured nation tariffs, even in the presence of exporter and importer fixed effects. A byproduct of our approach is that it can be used to recover estimates of the trade elasticity, a key parameter for quantitative trade models. We demonstrate the effectiveness of our techniques in the case of most favoured nation tariffs and “time to export” as representative non‐discriminatory determinants of trade on the importer and on the exporter side, respectively. Our methods can be extended to quantify the impact on trade of any country‐specific characteristics as well as any non‐trade policies.     

The influence of international trade on labour productivity in services: The case of Brazil in the 1990s

In the developing world, services account for a rising share of domestic employment and international trade. Thus, it is important to know whether trade liberalization contributes to labour productivity in services. We explore this question, examining the 1990–2000 Brazilian trade liberalization. We find that growth of imports and exports strengthened labour productivity in services, but the contribution was smaller in subsectors with more college graduates, and this negative offset was larger in subsectors that received large foreign direct investment (FDI) inflows. Improved access to imported manufactured intermediate inputs raised downstream services' labour productivity and downstream manufacturing firms benefitting from tariff cuts enacted by trade partners generated spillovers that improved the labour productivity of upstream service subsectors. However, FDI inflows and investments in human and physical capital modified these downstream factors. We conclude that the Brazilian trade liberalization strengthened productivity in services, but unequally across subsectors.     

Ranking the optimum tariff and the maximum revenue tariff in vertically related markets

This paper firstly shows that in a vertically related industry with either domestic upstream monopolist or foreign upstream monopolist, when the upstream firm adopts uniform input pricing, the optimum-welfare tariff is higher than the maximum-revenue tariff, if the number of foreign competitors is sufficiently large. Secondly, when domestic upstream monopolist adopts discriminatory input pricing, the maximum-revenue tariff is higher than the optimum-welfare tariff. Thirdly, when foreign upstream monopolist adopts discriminatory input pricing, the optimum-welfare tariff will exceed the maximum-revenue tariff if the sizes of domestic and foreign firms become more unequally distributed.     

Trade Liberalization and the Profitability of Mergers: a Global Analysis*

We analyze the effects of bilateral tariff reductions on the profitability of cost‐reducing horizontal mergers. Given Cournot competition in a two‐country world, for any positive tariff below a certain threshold, marginal trade liberalization is shown to encourage only those domestic mergers with sufficiently large cost‐savings and to discourage the rest. For tariffs close to, but smaller than, the prohibitive tariff, however, marginal trade liberalization necessarily encourages all domestic mergers. Moreover, we show that for a given level of cost‐savings, the impact of marginal trade liberalization may not reliably predict that of nonmarginal liberalization. Although at high tariffs, domestic mergers are shown to be unambiguously more profitable than cross‐border mergers, near free trade, mergers which yield the most cost‐savings become the most profitable. Thus, when comparing domestic and cross‐border mergers, trade liberalization encourages the type which yields the most cost‐savings.     

The puzzle of quality upgrading of Chinese exports from the trade liberalization perspective

Trade liberalization could accelerate the process of quality upgrading through the competition effect. However, that the quality of Chinese exports exhibits an opposite performance pattern is puzzling. The present paper uses a framework based on multiproduct firms to analyse the mechanism of how the product quality of exports is affected by trade liberalization to explain this puzzle. The model includes two major mechanisms: the competition effect and the market effect. There is a huge gap in the influence on the product quality of exports between a decrease in tariff barriers and non‐tariff barriers: firms' product quality increases (decreases) when non‐tariff barriers (tariff barriers) fall. The data of Chinese firms from 2001 to 2011 supports this conclusion. Further research reveals that the influence of trade liberalization on the product quality of exports in China varies among different types of firms.     

How did wars dampen trade in the MENA region?

The article investigates the impact of wars on trade in the Middle East and North African region. Using an augmented gravity model that controls for the endogeneity problem in our estimation, we introduce a war variable and distinguish between different types of conflicts. The results show that wars have a significantly negative impact on exports, imports and trade. Civil conflicts hinder exports, imports and trade significantly. The disaggregated version of the gravity model shows that non-state conflicts have a detrimental effect on bilateral trade flows in manufacturing, and that none of the conflicts do affect trade in services. We also find that, on average, a conflict is equivalent to a tariff of 5% of the value of trade.     

Trade liberalization and trade performance of environmental goods: evidence from Asia-Pacific economic cooperation members

In this article, we study the impact of trade liberalization, including reductions in both tariff and nontariff trade barriers, on environmental goods (EGs) exports. Using bilateral trade data from 20 Asia-Pacific Economic Cooperation members, we find that tariff reduction in an exporting country has a larger positive impact on its exports of EGs than tariff reduction in an importing country. Our results also show that a lower nontariff barrier in an importing country increases its imports of EGs. A considerable amount of heterogeneity also exists in subsample results based on countries’ income levels.     

Has the Caribbean Basin Economic Recovery Act Achieved Its Stated Goals?

This paper examines the impact of CBERA (Caribbean Basin Economic Recovery Act) trade provisions to determine whether the program has achieved its stated goals. A major program enhancement had a negative impact across small beneficiaries, but countries with large manufacturing sectors were able to expand preferential export shares with negligible increases in total exports relative to GDP. Additional evidence supports the view that tariff preferences did not promote economic development in CBERA-eligible countries. Greater utilization of CBERA trade provisions will require expanding coverage to include all products of export interest to beneficiaries and reducing costs associated with administrative regulations and rules of origin.
