Differentiated products and evasion of import tariffs

An emerging literature has demonstrated some unique characteristics of trade in differentiated products. This paper contributes to the literature by postulating that differentiated products may be subject to greater tariff evasion due to the difficulties associated with assessing their quality and price. Using product-level data on trade between Germany and 10 Eastern European countries during 1992–2003, we find empirical support for this hypothesis. We show that the trade gap, defined as the discrepancy between the value of exports reported by Germany and the value of imports from Germany reported by the importing country, is positively related to the level of tariff in 8 out of 10 countries. Further, we show that the responsiveness of the trade gap to the tariff level is greater for differentiated products than for homogeneous goods. A one-percentage-point increase in the tariff rate is associated with a 0.4% increase in the trade gap in the case of homogeneous products and a 1.7% increase in the case of differentiated products. Finally, the data indicate that tariff evasion takes place through misrepresentation of the import prices rather than underreporting of quantities or product misclassification.     

Trade protection and tax evasion: Evidence from Kenya,Mauritius, and Nigeria

We examine the effect of trade protection rates on evasion in three African countries Kenya, Mauritius, and Nigeria. In capturing the effect of trade protection on tariff evasion, we use a much improved measure of trade protection (MAcMap-HS6 2001 and 2004). For two of these countries, this dataset allows the novelty of using variation in trade protection across product, time, and trading partners leading to significantly refined estimates of evasion elasticity relative to existing studies on tariff evasion. We find a robust evidence for positive elasticity of evasion with respect to tariffs in Kenya and Nigeria with relatively weaker evidence for Mauritius. Our results match the rankings of countries in institutional quality. Greater responsiveness of evasion to the level of tariffs is established in Nigeria (comparatively weak institutional quality) vis-à-vis Kenya, and in Kenya vis-à-vis Mauritius (comparatively good institutional quality). This pattern is preserved even when focusing on same set of trading partners and same set of imported products for the three countries. This result is robust to controlling for protection on related products (that creates incentives/ opportunities for evasion) and also for degree of differentiation of the product and some other characteristics.     

Export promotion activities in developing countries: What kind of trade do they promote?

Information problems involved in trading differentiated goods are a priori acuter than those associated with trading more homogeneous products. The impact of export promotion activities intending to address these problems can therefore be expected to differ across goods with different degree of differentiation. Empirical evidence on this respect is virtually inexistent. This article aims at filling this gap in the literature by providing estimates of the effect of these activities over firms trading different goods using highly disaggregated export data for the whole population of Costa Rican exporters over the period 2001–2006. We find that trade promotion actions favor an increase of exports along the extensive margin, in particular, in terms of destination countries, in the case of firms that are already selling differentiated goods. However, these actions do not seem to encourage exporter to start exporting these goods. Further, no significant impacts are observed for firms exporting reference-priced and homogeneous goods.     

Trade facilitation and the extensive margin

The literature on trade facilitation has mostly focused on implications for trade volumes. However, recent theoretical contributions have emphasized that trade costs – such as transaction costs related to cross-border trade procedures – affect both the traded volumes of ‘old’ goods (the intensive margin) and the range of traded goods (the extensive margin). This article therefore tests whether trade facilitation affects the extensive margin by counting the number of 8-digit products that are exported from developing to EU countries, and using this as the dependent variable in an estimation. Moreover, it also tests whether the extensive margins in differentiated and homogeneous goods are affected in the same way by transaction costs. Estimation results suggest that if export transaction costs – proxied by the number of days needed to export a good – declined by 1%, the number of exported differentiated and homogeneous products would rise by 0.6% and 0.3%, respectively. Policy simulations further illustrate that if all countries were as efficient at the border as the most efficient country at the same level of development, the number of exported differentiated and homogeneous products would increase by 62% and 26%, respectively.     

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.     

On necessarily welfare-enhancing free trade areas

The well-known Kemp-Vanek-Ohyama-Wan proposition establishes that if two or more countries form a customs union (CU) by freezing their net external trade vector through a common external tariff and eliminating internal trade barriers, the union as a whole and the rest of the world cannot be worse off than before. Owing to the fact that a Free Trade Area (whose member countries impose country specific external tariff vectors) does not equalize marginal rates of substitution across its member countries (in contrast to a CU), the literature has been unable to provide a parallel demonstration regarding welfare improving Free Trade Areas (FTAs). The present paper eliminates this gap. In extending the result to the case with intermediate inputs, the paper also sheds new light on the rules of origin required to support such necessarily welfare enhancing FTAs. We show here that provided no trade deflection is permitted, all that is required by way of rules of origin is that the goods produced within the union - whether final or intermediate - be allowed to be traded freely. The proportion of domestic value added in final goods does not enter as a criterion in the rules of origin.     

Trade and income convergence: Sorting out the causality

This paper studies the linkage between international trade and income convergence across countries. Different theories offer conflicting predictions regarding how they might affect each other. In the existing empirical literature estimating the trade impact on income convergence, a long-lasting problem is the reverse causality from income convergence to trade. This paper provides a disaggregated bilateral trade data analysis to solve this problem. The results show that the reverse causality from income convergence to trade exists in differentiated product sectors, but not in homogeneous product sectors. Trade in homogeneous sectors reduces the income gaps among trade partners, but it is not significantly affected by their income difference. Therefore, the negative effect of trade in homogeneous sectors on the income gap is free from the reverse causality problem. It can be taken as a pure evidence of trade-induced income convergence. This result is robust to various econometric methods.     

Tariff evasion in global trade data

ABSTRACT

We find evidence of pervasive tariff evasion in the global data on trade from 1988 to 2015. Using over 35 million observations of data on import and export flows at the HS6 product category level, we find evidence of substantial underreporting of imports relative to export data on average and particularly when tariffs on product categories are high. These effects are stronger in more corrupt destination countries, as measured by the World Bank's Worldwide Governance Indicators [World Bank. 2016. Worldwide Governance Indicators. September 25, 2016]. In addition, evidence of tariff evasion increases significantly in economic downturns. We document these patterns in the global data and explore the welfare effects of this evasion by (1) putting a lower bound on the extent to which there are revenue losses from tariff evasion, and by (2) estimating the effects of corruption as measured by this indicator on global trade in a simple gravity model. We estimate that in total, revenue losses from tariff evasion are currently likely to exceed 400 to 670 million USD globally per year, and find that the effects of corruption on trade flows are ambiguous overall but change from weakly positive (‘grease the wheels’) to largely negative over the years in our sample.     

Trade Creation and Diversion Effects of Regional Trade Agreements: A Product‐level Analysis

This paper examines the impacts of regional trade agreements (RTAs) on trade flows at product level, with a particular focus on trade creation and diversion. Based on estimation of the gravity equation, dealing with the zero trade flows and endogeneity bias problems, we analyse the impacts of various types of RTAs involving 67 countries for 20 products during the 1980–2006 period. We find that RTAs among developing countries tend to cause trade diversion compared with RTAs among developed countries. Taking the higher external tariff rates of developing countries compared with developed countries into consideration, our results suggest trade diversion is likely to be caused by remaining high tariffs on imports from non‐members. In addition, we find the trade creation effect for many products in the cases of Customs Unions and plurilateral RTAs. These results imply that trade creation would be caused by various factors besides the reduction in tariff rates. Based on these results, we draw a policy implication that external tariff rate reduction is an important factor in avoiding trade diversion in the formation of RTAs, in particular for RTAs among developing countries, while a large number of members and the common external tariff appear to be important for generating the trade creation effect.     

Trade Costs and Changes in Canada's Trade Pattern

This paper measures the size and composition of non‐tariff trade costs such as transport, wholesale, and network costs incurred in Canada's merchandise trade using Statistics Canada's latest ‘trade margins’ statistics. It examines how changes in these trade costs have influenced Canada's merchandise trade pattern and the course of economic integration. Our results show that as tariffs have been substantially reduced and largely abolished, costs associated with transport and distribution services now appear much larger than remaining customs duties; therefore, liberalisation in services might be the next key step in promoting greater merchandise trade. Further, reducing transport and other trade‐related costs has helped ‘reverse’ the ‘home market effect’, expanding Canada's domestic demand and production for exports of differentiated products.     

Non‐Tariff Measures,Specific Trade Concerns and Tariff Reduction

This paper studies the determinants of the recent proliferation of Specific Trade Concerns raised at the WTO on non‐tariff trade measures (NTMs), with a focus on sanitary and phytosanitary (SPS) and technical barriers to trade (TBTs). Even though NTMs are imposed de jure to protect consumers from unhealthy products, they increase trade costs de facto. So, when tariff protection lowers, NTMs become effective barriers to trade and the exporting countries can complain at the dedicated committee at the WTO (STCs). Therefore, we study whether STCs are raised by exporting countries as a consequence of tariff reductions in importing countries, that is when non‐tariff measures become barriers to trade. Using a recent database on STCs over the period 1996–2010, we find empirical evidence that SPS and TBT concerns are raised by exporting country as a consequence of importer's tariff cut.     

中美经贸摩擦如何影响了大豆进口——基于贸易转移与创造效应视角

中美经贸摩擦背景下,中国对美国大豆进行反制,加征25%关税,那么,中国对美豆加征关税,会对中国大豆来源布局和产业产生怎样影响。文章利用寡头竞争理论,使用2002年1月~2020年3月中国海关数据,利用进口需求模型(AIDS),分析了加征关税对农产品贸易可能发生的贸易损害、贸易转移和贸易创造效应。实证结果表明,中国对美国大豆并不存在刚性依赖,对美加征关税将发生显著贸易转移效应和创造效应。即对美关税每增加1%,将会导致其对中国大豆出口下降1.29%,对巴西大豆进口上涨0.67%,对阿根廷大豆进口上涨0.66%,对其他国家进口上涨1.03%。中国市场增长和加征关税,将会造成国际大豆贸易创造效应,并激发非传统国家进入大豆贸易市场。     

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.     

中国出口技术复杂度真的赶上发达国家了吗

使用HS(1992)六位数分类商品贸易数据,从"出口重叠指数"、出口商品"相对平均单位价值"、不同技术层面上的出口商品"相对平均单位价值"三个方面,以部分发达国家为比较对象,实证考察了中国出口技术复杂度变动趋势。结果发现,与现有大多研究结论不同:中国出口技术复杂度与发达国家相比,尚存一定差距,特别是在高技术密集型出口产品领域,差距较大,而目前对发达国家的追赶上,主要表现在中等技术密集型产品领域。中国出口品的"专业化"既没有与发达国家"趋同",其技术复杂度也未赶上发达国家,中国出口增长不会导致发达国家所谓"工资收入不平等"和"贸易条件恶化";立足现实比较优势,顺应国际分工发展大势,应是未来一段时间内中国进一步提升出口技术复杂度的出发点。     

Informality,tariffs and wealth

This article analyzes the interaction between changes in tariff protection, informality, inequality and aggregate income. First, we describe some new empirical evidence on informality, the formal/informal wage gap and trade openness in Latin American countries. Then we present a simple model characterized by three (empirically based) assumptions: (1) agents consume both formal and informal goods; (2) the government uses tariff revenues to purchase formal goods; (3) informality is a voluntary phenomenon. The model predicts that tariff reduction increases informality and wage inequality and that the maximization of income requires a positive level of tariff protection. The model's results are shown to be consistent with the empirical evidence concerning Latin American countries.     

Friends like this: The impact of the US–China trade war on global value chains

This paper considers the indirect impact the recent tariff increases between the United States and China can have on third countries through links in global supply chains. We combine data from input–output relationships, imports and tariffs, to calculate the impact of the tariff increases by both the United States and China on cumulative tariffs paid by third countries. We show that the tariff hikes increase cumulative tariffs for other countries and thus hurt trade partners further downstream in global supply chains. We also show that this is particularly important for tariff increases on Chinese imports in the United States. These are likely to be used as intermediates in production in the United States, which are then re-exported to third countries. The most heavily hit third countries are the closest trade partners, namely the EU, Canada and Mexico. We estimate that the tariffs impose an additional burden of around 500 million to 1 billion US dollars on these countries. China's tariffs on US imports have less of an effect.     

Trade Liberalisation and Economic Performance: Theory and Evidence for Developing Countries

The last five decades have witnessed a profound evolution of economic policy in developing countries, particularly in the case of trade strategies. Both internal, as well as external, factors have prompted the need for more outward‐oriented (or liberalised) trade policy regimes. The creation of the General Agreement on Tariffs and Trade (GATT) in 1947 and the World Trade Organisation (WTO) in 1995 have been important driving forces for free trade. Since then, the major quantitative barriers to trade, i.e. tariffs and non‐tariff barriers (quotas, licences and technical specifications, among other restrictions), have substantially been reduced or dismantled. Also, the progress towards more liberalised trade regimes, mainly in developing countries, has been manifested in the trade and development literature. Major studies suggest that the performance of more outward‐oriented economies is superior to that of those countries pursuing more inward‐looking trade practices (Greenaway and Nam, 1988; Dollar, 1992; Sachs and Warner, 1995; and Rodríguez and Rodrik, 2000). Recent developments in the international trade literature focus on the potential dynamic effects of trade liberalisation, i.e. simplification of tariff structures and elimination of non‐tariff barriers, in reducing the incentives to rent seeking and in accelerating the flow of technical knowledge from the world market. Moreover, there have been important advances regarding the study of trade liberalisation and its impact on exports, imports and the balance of payments, largely neglected in the literature, often driven by supply‐side considerations.

Tariffs and formation of free trade agreements networks

This paper examines the formation of bilateral free trade agreements (FTAs) on the basis of country heterogeneity in the tariff level. We demonstrate that a country's unilateral incentive to form an FTA depends on the relative magnitudes of the (negative) market concession effect and the (positive) market expansion effect, both of which are determined by the tariff levels of the two FTA partner countries. Global welfare is maximised when all country pairs form FTAs. Two countries in equilibrium are more likely to form an FTA when their tariff gap is smaller or when their tariff levels are neither very high nor very low. This finding is robust to several extensions of the model. Our preliminary empirical analysis provides some evidence for the finding.
