Smuggling and Bhagwati's Nonequivalence Between Tariffs and Quotas

The authors extend Professor Bhagwati's analysis about the nonequivalence between trade policy instruments when domestic production is monopolized and the terms of trade are endogenous, by allowing for smuggling. They show that the dominance of the ad valorem tariff over the quota is not robust. Tariffication can lower welfare even when the level of illegal imports is quite small. However, tariffication with a specific tariff is always beneficial because the specific tariff dominates the ad valorem tariff and the quota with or without smuggling. Smuggling (or the threat) also tends to lower the second–best tariff/quota, and increases welfare when imports are restricted by a quota, but lowers it under a tariff.     

Impact of tariff rates on the probability of trade relationship survival: Evidence from ASEAN+6 manufactured goods

This article explores the links between imported trade relationships, their duration and tariff rates. We use survival analysis to investigate how the probability of trade relationship survival is affected by the difference in the tariff rates. We use the ASEAN+6 as the basis of our report and consider a total of 89 trading partners for manufactured goods from 1996 to 2011. Our findings are as follows. First, low‐tariff trade survives longer than high‐tariff trade of manufactured goods. Second, we find a significantly negative correlation between tariff rates and duration, and regional trade agreements help prolong the length of trade relationships. Third, the hazard ratios of intraregional differentiated goods and the parts and components trade are lower. We have also obtained robust results for distinct specifications through consideration of production networks and Rauch's product classification. Finally, we believe that these findings could be used as a reference for other economic organizations working toward the diminution of tariff rates.     

On the Equivalence of Tariffs and Quotas under a Revenue Constraint

This paper sets out a duopolistic model to examine the price and welfare equivalence of tariffs and quotas, given the quota rent is equal to the tariff revenue. It shows that the domestic welfare ranking of the two trade policies crucially depends on the relative costs of the domestic and foreign firms; when the domestic firm's relative costs are lower than those of the foreign firm, a quota regime generally leads to a higher welfare level than that of an equivalent tariff regime. This finding contrasts sharply with the conclusions of Dasgupta and Stiglitz (1977 ), where it was found that a tariff regime always generates higher domestic welfare.     

Tariff evasion and rules of origin violations under the Canada‐U.S. Free Trade Agreement

Abstract Using product‐level data on trade between Canada and the U.S., this paper presents evidence of tariff evasion and violation of the rules of origin occurring under the Canada‐U.S. Free Trade Agreement (CUSFTA). It shows that more imports go unreported at the destination country when tariffs are higher. Consistent with the tariff evasion hypothesis, this result implies that the trade creation effect of a free trade agreement may in fact be due to less underreporting. Further, this paper shows that the larger Canadian tariff preference margin for the U.S. is associated with more goods originating in third countries being transshipped through the U.S. territory for re‐export. The preference margin is also positively correlated with the value of excess imports from the U.S., which qualify for preferential treatment. Both results suggest the presence of persistent violations of CUSFTA’s rules of origin.     

Import sensitive products and perverse tariff‐rate quota liberalization

Abstract This paper shows that a Tariff‐Rate‐Quota's (TRQ) minimum access expansion can perversely trigger domestic price increases. Often, TRQs have prohibitive over‐quota tariffs to mimic import quotas in providing minimum market access. In the WTO's Doha Round, it is likely that countries using TRQs will avoid aggressive tariff reductions if they increase the quota portion of TRQs. We show that when the import price lies between the unit cost of production and the price received by domestic upstream firms, an increase in import quota as a share of domestic production may cause an increase in the domestic retail price.     

PERFORMANCE CONTINGENT PROTECTION*

In this paper we ask how to construct a tariff or quota schedule which depends on the behavior of a domestic monopsonistic monopolist in order to achieve the best tradeoff between two objectives of a government. We consider various political and economic tradeoffs which could face the policy maker: aggregate welfare versus industry profits, output and imports; and trade barrier revenue versus industry profits and domestic price. In all cases considered, performance contingent protection which takes the form either of a tariff which depends on domestic output or a quota which depends on the price charged is generally superior to a fixed tariff or quota and is sufficient to achieve optimality.     

Trade policy in a Ricardian model with a continuum of goods under nonhomothetic preferences

We study the effects of trade liberalization in a Ricardian trade model with a continuum of goods and nonhomothetic preferences. Goods are ordered according to priority, and higher-ranked goods are consumed only by richer households. South (North) has a comparative advantage in the lower- (higher-) ranked goods. South's terms-of-trade unambiguously deteriorate as a result of unilaterally reducing its tariffs. North, by contrast, may experience a terms-of-trade gain when liberalizing its trade. It appears that the redistribution of tariff revenue from rich to poor households within each country increases the burden of trade liberalization for poor households.     

The Mercantilist Index of Trade Policy*

We introduce an index of trade policy restrictiveness defined as the uniform tariff that maintains the same trade volume as a given tariff/quota structure. Our index overcomes the problems of the trade‐weighted average tariff: It avoids substitution bias, correctly accounts for general equilibrium transfers, and takes import volume instead of welfare as benchmark. Empirical applications to international cross section and time‐series comparisons of trade policy confirm our theoretical results: Trade‐weighted average tariffs generally underestimate the true height of tariffs as measured by the trade‐volume‐equivalent index; this in turn always underestimates the welfare‐equivalent index.     

Tariff escalation and invasive species damages

We investigate the interface between trade and damages from invasive species (IS), focusing on escalation in tariffs between raw-input and processed-good markets, and its implication for IS-based damages. The current tariff escalation in processed agro-forestry products motivates our analysis. Tariff escalation exacerbates the likelihood of IS introduction by biasing trade flows towards increased trade of primary commodity flows and against processed-product trade. We show that a reduction of tariff escalation, by lowering the tariff on processed goods increases allocative efficiency and reduces IS-based damages, a win-win situation. We also identify policy menus for trade reforms involving tariffs on both raw input and processed goods leading to win-win situations.     

State Trading and Tariff Rate Quotas: The Case of Korea's Rice Imports

This paper analyzes the effects of trade liberalization of tariff‐rate quotas under import “state trading enterprises” (STEs) in agriculture. An analytical framework is provided to determine the importance of which instrument is binding under competition (the in‐quota or out‐of‐quota tariff or the quota) and under the initial STE equilibrium. It also depends on whether or not the STE controls both the domestic market prices and owns/controls the import quota (and whether it is obligated to fill the quota or not). An empirical example of the rice STE in South Korea has simulations showing that an increase in imports can be achieved through a moderate expansion of the quota or a decrease in the out‐of‐quota tariff to the level where it becomes binding. However, a significant level of quota expansion induces the STE to switch to the autarky solution and social welfare declines.     

The “Emulator Effect” of the Uruguay Round on US Regionalism

Using a detailed data set at the tariff line level, we find an emulator effect of multilateralism on subsequent regional trade agreements (RTAs) involving the USA. We exploit the variation in the frequency with which the US grants immediate duty free access (IDA) to its RTA partners across tariff lines. A key finding is that the US grants IDA status especially on goods for which it has cut the multilateral most favored nation (MFN) tariff during the Uruguay Round the most. Our results suggest that the Uruguay Round multilateral “concessions” have elicited subsequent preferential trade liberalization.     

The Moral Hazard Play: A Review of The Chastening: Inside the Crisis that Rocked the Global Financial System and Humbled the IMF

We estimate the influence of trade preferences granted by Argentina on the origin of its imports. We try to identify if changes in Argentina's trade policy toward a set of countries had a differential effect, depending on whether goods were already traded, or on the contrary, if tariff changes affected mostly imports of new goods. We distinguish between the effects of changing tariffs and changing trade preferences. The econometric evidence shows that the effect of changes in tariff preferences on the probability of Argentina importing from other Asociación Latinoamericana de Integración (ALADI) members has been rather small, with most of the effect being explained by changes in tariff rates levied on imports from these countries. This result is stronger in the case of imports from Brazil.     

PREFERENTIAL TRADE AGREEMENTS AND MULTILATERAL TARIFF COOPERATION*

Are preferential trade agreements (PTAs) building or stumbling blocks for multilateral trade liberalization? I address this question in an infinitely repeated tariff game between three countries engaged in intraindustry trade under oligopoly. The central result is that when countries are symmetric, a free trade agreement (FTA) undermines multilateral tariff cooperation by adversely affecting the cooperation incentive of the nonmember whereas a customs union (CU) does so via its effect on the cooperation incentives of members. However, when countries are asymmetric with respect to either market size or cost, there exist circumstances where PTAs facilitate multilateral tariff cooperation.     

Technological Upgrading under Tariffs and Equivalent Quotas*

This paper compares the effect of tariffs and that of equivalent quotas on the domestic firm’s production technology choice when it competes with a foreign firm in the domestic market. It is shown that under Bertrand price competition, the ranking of technology under tariff protection and quota protection is ambiguous, as it depends on the relative strength of the strategic vs output effects. The equivalent quota regime can generate a higher‐technology (implying a lower production cost) choice than the tariff regime if the strategic effect dominates the output effect. In contrast, the technology level is necessarily higher under the tariff regime than under the equivalent quota regime when the firms engage in Cournot quantity competition.     

Tariffs versus quotas in the presence of imperfect competition and cross‐border externalities

Abstract.  We consider trade policies intended to affect the production of a foreign monopolist that generates negative externalities. We derive the optimal tariff and optimal import quota and examine which policy measure should be used to maximize domestic welfare. We find that if the domestic government does not have full information on the foreign firm's production method and if cross‐border externalities exist, import quotas are in some cases preferable to tariffs. Otherwise, however, tariffs are preferable to quotas. JEL Classification: F13, F18     

Domestic trade protection in vertically-related markets

We consider trade policy in a setting where home country firms are fully dependent on vertically-integrated foreign firms for supplies of a key input. We find that vertically-integrated firms' strategic considerations play an important role and that, in particular, a tariff on final goods may either increase or decrease the domestic price of final goods. The import of final goods is always taxed to extract and shift rents from foreign firms, while the import of intermediate goods can be either taxed or subsidized. The market structure is shown to be an important consideration when making trade policy.     

Importing under trade policy uncertainty: Evidence from China

This paper empirically explores the adjustment of imports to reductions in trade policy uncertainty (TPU), taking into account that firms may face large sunk costs when purchasing foreign goods. We investigate how product-level Chinese imports react to tariff binding arising from China's accession to the WTO, by distinguishing both country-related and firm-related margins. Our main results suggest that a decline in TPU allows access to a greater variety of foreign goods, that are also associated with higher quality. At the same time, tariff binding leads more Chinese producers and trade intermediaries to start importing, thus allowing a greater number of firms and consumers to enjoy potential gains from imports. Finally, we document heterogeneous TPU effects across firms with different ownership, as well as across products with different end use, revealing interesting insights into the context of global value chains.     

Tariffs in a Ricardian Model with a Monopolistically Competitive Sector: the Role of Nontradables

It is shown that for a small open economy the welfare effects of a tariff on the import of the brands of a differentiated good depends crucially on the pattern of trade. The literature has shown that welfare rises when the domestic brands are nontraded. But when the domestic brands are traded, the imposition of a tariff lowers welfare by shifting demand towards the nontraded homogeneous good which causes exit from the differentiated goods industry.     

Why Free Trade May Hurt Developing Countries

This paper builds a general equilibrium trade model where a country produces two traded goods and one nontraded public consumption good. The government finances the provision of the public good by taxing the incomes of factors of production, and/or by imposing tariffs. Within this framework, the paper (i) shows that a small tariff or an income tax improves the country's welfare if there is an undersupply of public good, and (ii) identifies the circumstances in which an improvement in the country's terms of trade may reduce its welfare, and free trade can be inferior to autarky. A terms of trade improvement, or the movement from autarky to free trade, definitely improves the country's welfare if the government imposes a tariff that leaves the domestic relative price of the imported good unchanged.     

Revenue‐enhancing Trade Liberalization in a Differentiated Duopoly

Existing studies suggest that in developing countries, tax reforms that increase consumption taxes can compensate for shortfalls in revenue from a tariff reduction. However, these revenue‐enhancing tariff–tax reforms have a critical shortcoming—they generally reduce welfare under imperfect competition. This paper shows that tax reforms such as consumption tax reforms do not necessarily have to be implemented to make up for revenue shortfalls from tariff reductions under imperfect competition, because trade liberalization through tariff cuts leads to an increase in government revenue when domestic and imported goods have a high substitutability. This revenue‐enhancing effect of a tariff reduction occurs for a wider degree of product substitutability when initial tariff and consumption tax rates are high. More importantly, we show that even if initial tariff and consumption tax rates are sufficiently low, a tariff reduction still increases government revenue for a low degree of product differentiation under Bertrand competition.
