Input tariff liberalisation and servitisation in manufacturing: Evidence from China's WTO accession

This paper links the sharp drop in China's manufacturing servitisation (MS) in early 21st century to China's accession to WTO featured by conspicuous input trade liberalisation (ITL). The results show that manufacturing industries exposed to higher degree of ITL suffer more MS declines after China's accession to the WTO. Heterogeneous analysis shows that industries with high import intensity, capital intensity or technology intensity suffer more MS declines following input trade liberalisation. Further analysis shows that input trade liberalisation increases the import of intermediate inputs while significantly reduces the proportion of service imports for manufacturing industries. The results are robust to a series of robustness checks.     

Trade openness and the environmental Kuznets curve: Evidence from Chinese cities

This paper examines the impact of economic growth and trade openness on environment in 261 Chinese cities over the period of 2004–2013, using recently developed continuously updated fully modified method which allows for both cross-sectional dependence and endogeneity. Two types of pollutants, industrial waste water and sulphur dioxide are investigated, and three measures of openness are employed in the regression. From the results, we find that the environmental Kuznets curve hypothesis holds not only for the whole China, but also in different regions. It is estimated that wastewater pollution increases with economic development until per capita GDP reaching the turning point of 42,991–48,828 yuan (in constant 2002 price), which varies depending on the specific measure of trade openness. The turning point for sulphur dioxide is found to occur at a much lower income level around 9,588–10,663 yuan per capita GDP. Furthermore, export is mostly found to be positively related with pollution and the impact of import is likely to be negative for both the whole China and across regions, if the significance is identified in the estimation results.     

Fending off waste from the west: The impact of China's Operation Green Fence on the international waste trade

China launched the first Operation Green Fence (OGF) on 1 February 2013 to fend off inflows of illegal waste. The main objective of OGF was to enforce waste trade policies already adopted by China and thereby restrict illegal waste imports. We use a gravity model of international trade with annual bilateral waste trade data at the 6-digit HS code level to assess the impact of OGF on the international waste trade. First, we study the direct impact of OGF and find that the intervention resulted in a 26% drop in low-quality waste exports to China from developed countries. Second, we assess the impact of OGF on exports from developed countries to developing countries, excluding China. We do not find a statistically significant effect of OGF on low-quality waste exports from developed countries to developing countries (excluding China). We also test the waste haven hypothesis and do not find evidence that waste exports were disproportionately diverted to countries with lax environmental regulation.     

Input trade liberalisation,institution and markup: Evidence from China's accession to the WTO

This paper investigates the effects of input trade liberalisation on firm markups and assesses how institutional environment affects such impacts by using Chinese firm‐level data. To identify the causal effects, we exploit the quasi‐natural experiment of China's WTO accession in 2001 and perform difference‐in‐differences estimation. The results show that input tariff liberalisation leads to a substantial increase in firm markups, and institutional environment significantly strengthens such an impact. We further uncover the underlying mechanisms through which input tariff liberalisation boosts firm markups, and show that both price and cost channels work for the input tariff cut effect on firm markups, of which the latter is much more important. In addition, we also demonstrate that input tariff cut significantly fosters aggregate markup growth, and the reallocation effect is found to be an important channel through which input tariff liberalisation boosts aggregate markup growth.     

The impact of trade liberalization on productivity: Evidence from India's formal and informal manufacturing sectors

Despite a large literature investigating the impacts of trade on firm productivity, there is almost no evidence on how small firms react to trade liberalization. Using a unique dataset of firm-level surveys that are representative of the entire Indian manufacturing industry, I show that India's unilateral reduction in final goods tariffs increased the average productivity of small, informal firms, which account for 80% of Indian manufacturing employment but have been excluded from previous studies. In contrast, the increase in productivity among larger, formal firms was driven primarily by the concurrent reduction in input tariffs. By examining the effect of the tariff liberalization on the distributions of productivity and firm size, I find evidence consistent with the exit of the smallest, least productive firms from the informal sector. In addition, I find that although the decline in final goods tariffs did not significantly impact average formal sector productivity, it did increase productivity among the top quantiles of the distribution.

Trade liberalization,free trade agreements,and the value of firms: Stock market evidence from Singapore

We examine the effects of the United States–Singapore Free Trade Agreement (FTA) on the value of firms listed in the Singapore Exchange using event study analysis. Despite the predictability of the FTA negotiations, we find that one event – the removal of the last obstacle to the free trade deal in January 2003 – increases the value of firms in some industries by 1–11% on average. These results indicate that trade liberalization and FTAs do increase the value of firms.     

Trade in tourism services: Explaining tourism trade and the impact of the general agreement on trade in services on the gains from trade

The article addresses two questions related with tourism as a service trade. Can tourism be explained as other export activities? Does service liberalisation have a positive or negative impact on tourism receipts in destination countries? Previous research has either focused on the demand side factors (i.e. factors of demand in the origin countries) or on tourism as a long-run factor of economic growth. The research shows that a complementary perspective such as that offered by trade in a supply side perspective can render additional insights towards understanding tourism. This approach can explain why countries have absolute and comparative advantage. Another finding is that tourism as an export can be explained by some of the same destination factors that explain other service exports. Using different panel estimators the importance of supply side factors that are to some extent exclusive to tourism are demonstrated: the general price competitiveness of the destination, tourism infrastructure and the provision of safety. The econometric models also confirm the relevance of other conventional explanatory factors of trade in services such as GDP per capita and internet usage. The last part of the article analyses the welfare gains from trade under the general agreement on trade in services (GATS). The revenue (tourism receipt) effect is decomposed into a volume (arrival) and price effect. Results suggest that liberalisers under the GATS gained especially from a volume effect with average higher growth rates in the number of arrivals. There is also found to be a positive effect on the average income earned per tourist from being a liberaliser.     

Trade liberalization and the environment: The case of intra-industry trade

Abstract

While a large body of literature examines the environmental impact of trade on the environment, this discussion focuses largely on the context of inter-industry trade. Empirical evidence has long suggested that an increasing share of international trade takes the form of intra- rather than inter-industry trade. In an attempt to fill this gap, the present paper uses a price-setting duopoly model of intra-industry trade to highlight the environmental consequences of trade liberalization when oligopolistic rivalry rather than comparative advantage drives international trade. We find that the environmental impact of trade liberalization depends mostly on two factors, namely, on the nature of pollution (i.e. whether it is local, transboundary or global) and on which country liberalizes trade (i.e. whether it is the ‘clean’ country or the ‘dirty’ country).     

The biggest losers (and winners) from US trade liberalization

Many development experts worry that continuing reductions of tariff levels in high-income countries will limit trade flows from developing countries that benefit from preferential trade programs because of ‘preference erosion.’ Using a panel of US import data between the years of 1997 and 2005, I find that reductions in preference margins will significantly diminish imports of some products, particularly from lower-middle and low income countries; for example, a 1% reduction in the US tariff on a product that is currently imported duty-free from developing countries will decrease imports of that product from lower-middle income countries by an average of 2.6%. However, many products produced by developing countries fail to qualify for preferential tariffs, thus a gradual reduction in all US tariff rates is expected to have only a modest impact on trade flows from developing countries.     

The role of processing trade in exporters' responses to exchange rate: Evidence from China

Processing trade is an important exporting mode for many countries developed by the export-oriented industrialisation such as 1960s Japan, 1990s Korea and 2000s China. Exporters who rely on processing trade for foreign profits do not enjoy much market power, and hence care more about exchange rate changes. We develop a model to illustrate how processing trade affects exporters' responses to exchange rate fluctuations. The model suggests that the elasticity of export price with respect to exchange rate for processing-trade exporters is greater than that of the ordinary-trade exporters, while the elasticity of export quantity of processing-trade exporters is smaller compared to their ordinary-trade counterparts. Most developing countries' governments offer processing-trade exporters better tax/tariff reduction policy to encourage exporting, which grants processing-trade exporters additional advantage to adjust more on export price and less on quantity when facing changes in exchange rate and therefore causes their different responses to exchange rate fluctuations. We find strong empirical supports by studying the data from China, which is the largest developing country and biggest processing-trade exporter.     

The effect of foreign trade and investment liberalization on spatial concentration of economic activity

I examine the varying responses of countries to foreign trade and direct investment liberalization on spatial concentration of their economic activity by taking into consideration moderating factors such as their market size and level of economic development. I argue that liberalization increases the concentration under normal conditions but large market size, and underdevelopment can disperse economic activity. Using data from 168 countries for the period of time starting in 1980s, I found support for all hypotheses.     

The labor market effects of the China Syndrome: Evidence from South Korean manufacturing

We evaluate the direct impact of China trade shock on the Korean labour market following the approach of Acemoglu, Autor, Dorn, Hanson, and Price (Journal of Labor Economics, 2016, 34, S1). Using firm- and industry-level data for the period 1993–2013, our direct estimates imply that the net employment effect of the China shock in the manufacturing sector is the creation of 0.52 million jobs. The positive impact is mostly driven by China's rising demand for intermediate inputs and capital goods from Korea to support its export expansion to the global economy. The import-competition channel plays a negligible role in manufacturing employment because it creates temporary jobs that merely compensate for the loss in permanent jobs. By contrast, over the same period, the average wage declined by 2.4%, and income inequality, measured as the gap between the high- and low-income quantile, grew substantially in manufacturing. In addition, we find that the direct effect of China shock lowers labour market concentration by shifting workers from big firms to small- and medium-sized firms.     

Estimating the pro-competitive gains from trade liberalization: an application to Mexican manufacturing

An original two-stage method is proposed to estimate the pro-competitive gains from trade liberalization. In a first step, I estimate the sensitivity of the price-cost margins of domestic firms to changes in the effective rate of protection, on the basis of a structure-performance relationship. This parameter is later exploited in a second step, where the cost of protection is calculated on the basis of a simple partial equilibrium model where domestic and foreign goods are imperfect substitutes. Applied to the Mexican case, this estimation reveals that protection removal depresses margins significantly and suggests that important additional gains can be expected from pro-competitive forces.     

Anti‐dumping duty circumvention through trade rerouting: Evidence from Chinese exporters

We study the evasion of US anti‐dumping duties by some Chinese exporters through trade rerouting via third countries or regions. Using detailed monthly trade data reported by China and the US Customs during the period of 2002–06, we find that US anti‐dumping actions against China lead to a stronger positive correlation between US imports from third countries and Chinese exports to the same third countries. Such a positive correlation is more pronounced for the products subject to anti‐dumping duties (treatment groups) than similar products not subject to these duties (control groups). The evidence is stronger for less‐differentiated products whose certificates of origins are easier to be modified and is stronger for third countries where the rerouting cost is low. These findings are consistent with a trade rerouting story, rather than a simple story of trade diversion (i.e., increase in some third countries' imports from China) and trade deflection (i.e., increase in some third‐country exports to the US). We also rule out other alternative stories, consider prior production in third countries and concurrent anti‐dumping actions against China or third countries, pay a particular attention to the many zero trade flows in the monthly level data and check the robustness to using an alternative control group and quarterly data, etc.     

Indirect network effects and the impact of trade liberalization: A note

In this note, we examine how trade liberalization affects production structure in the presence of indirect network effects (hardware/software systems). For these purposes we construct a simple two-country model of trade with two incompatible hardware technologies. It is shown that, given that both types of hardware exist before trade liberalization, liberalization and increased intra-industry trade in software products may reduce the variety of hardware technology via intensified network effects. It is also shown that, contrary to the findings of previous studies on intra-industry trade, some consumers may become worse off as the result of trade.     

The effect of trade liberalization on child labor

The question of how trade liberalization affects the employment of children in developing economies is at the core of the debate on globalization. Trade theory predicts that an increase in the price of an exported good could either increase or decrease child labor depending on the magnitudes of the substitution and income effects. In this paper, we study the relationship between changes in the relative price of an exported commodity and child labor using household-level data from within a poor country. In particular, we relate child labor to regional and intertemporal variation in the real price of rice surrounding national and international rice market integration in Vietnam. We find that higher rice prices are associated with declines in child labor. Income effects play an important role in this relationship. Rice price increases are associated with the largest declines in child labor in households that are large net producers of rice. These findings show that greater market integration can be associated with less child labor. Moreover, our results suggest that the use of punitive trade sanctions on exports from developing countries to eradicate child labor is unlikely to yield the desired outcome.     

The clash of liberalizations: Preferential vs. multilateral trade liberalization in the European Union

Preferential trade agreements (PTAs) are characterized by liberalization with respect to only a few partners and thus they can potentially clash with, and retard multilateral trade liberalization (MTL). Yet there is almost no systematic evidence on whether the numerous existing PTAs actually affect MTL. We provide a model showing that PTAs hinder MTL unless they entail accession to a customs union with internal transfers. Using product-level tariffs negotiated by the European Union (EU) in the last two multilateral trade rounds we find that several of its PTAs have clashed with its MTL. However, this effect is absent for EU accessions. Moreover, we provide new evidence on the political economy determinants of trade policy in the EU.     

环境规制对中国对外贸易竞争力的影响研究 ——基于中国省际面板数据的实证检验

基于全球经济失衡与中国贸易收支持续顺差的事实,欧美国家继"人民币汇率操纵论"之后又抛出"中国环境威胁论",认为中国贸易竞争力源于宽松的环境规制政策。本文使用面板数据方法对中国区域环境规制对贸易竞争力的影响进行了实证检验,结果显示中国区域贸易竞争力并非源于"宽松环境规制"。欧美国家提出的"中国环境威胁论"及相应的"碳排放边界调节税"只不过是单边贸易保护主义的借口。     

Gains from trade in used goods: Evidence from automobiles

I investigate the welfare effects of trade liberalization by exploiting a natural policy experiment in the economy of Cyprus. A 1993 law relaxed import restrictions on used vehicles and enabled the importation of second-hand Japanese automobiles into the country. This led to a dramatic shift of consumer purchases from new to used cars and a substantial expansion of the overall market. Welfare gains computed from a structural demand system average $2000 per purchaser per year over a four-year period after the policy change. The findings are suggestive of the potential for substantial gains from liberalizing trade in used goods.
