Tariff rate quotas: structural and stability impacts in growing markets

This paper examines several aspects of tariff rate quotas (TRQ) as adopted during tariffication of agricultural policies under the Uruguay Round of GAIT. Quota rents and non-tariff barrier effects may remain under TRQs, contrary to the objectives of the tariffication process. Further, price stability impacts of a TRQ are more complex than those for either tariffs or quotas, and under certain circumstances TRQs may be more stabilizing than either case, since TRQs truncate domestic production distributions much like price bands policies. This complexity results from the possibility of regime switching, and may reflect behavior under either a tariff, a quota, or a combination of cases. A TRQ policy may affect the timing of import decisions based on incentives created under quota allocation procedures envisioned for this institution. It may also allow increased imports as demand growth occurs because the quota is not necessarily a binding constraint. This means the above quota tariff is the critical policy instrument. An empirical study of Philippines port: imports illustrates these issues.     

TRQ‐complications: who gets the benefits when the EU liberalizes Mercosur's access to the beef markets?

The European Union (EU) and the Mercosur countries resumed negotiations on trade liberalization in May 2010 after several years of interruption. The article analyzes who stands to benefit and who is likely to lose if the EU liberalizes Mercosur's access to domestic beef markets. This economic assessment is performed using a partial equilibrium model for beef operating at a low level of product aggregation, paying specific attention to the role of Tariff Rate Quotas (TRQs). Consultations with experts from the meat sector allowed us to identify the allocation of the quota rents to different stakeholders. Under an agreement based on the EU's negotiation proposal, trade impacts are projected to be small due to the present quota overfill. As expected, impacts are more pronounced under the conditions set out in Mercosur's proposal. The results confirm that the distribution of quota rents can be decisive in determining welfare effects.     

The Liberalisation of Tariff Rate Quotas under Oligopolistic Competition

Several proposals for liberalising agricultural tariff rate quotas (TRQs) have been proposed within the WTO Doha Development Round. The literature suggests that the effectiveness of liberalisation depends upon which of the three elements of a TRQ constrains imports. Most contributions assume perfect competition. This article uses an oligopoly two‐stage capacity constrained model, in which the mode of competition is endogenous, to investigate the impact of different liberalisation options of TRQs, that is, the reduction in the in‐quota and out‐of‐quota tariffs and the expansion of the quota. This article shows that consideration of the nature of competition between traders may provide unconventional conclusions about the effectiveness of the various TRQ liberalisation options; furthermore, the article shows how an increase in the number of rivals, under certain circumstances, may be more effective in increasing trade than reducing tariffs.     

An Economic Investigation of the Import Licensing Methods and TRQs in Agriculture

Tariff-Rate Quotas (TRQs) were introduced at the outset of the Uruguay Round to support market access following the tariffication of non-tariff barriers to trade in agriculture. TRQs created an administrative mess in which governments often discretionarily allocate import licenses to private and/or public firms. Numerous papers describe the arbitrarily chosen procedures used to allocate licenses in different countries and the resulting distorted trade patterns. However, few research efforts have formally studied the impacts of different administrative methods on welfare. Due to significant spreads between domestic and world prices, the administration of import licenses can have important strategic effects under imperfect competition. We propose a simple theoretical framework to highlight the various economic implications of two methods used by WTO members: the historical allocation and the first-come-first-serve procedures. These two methods differ in their discretionary degree and, under imperfect competition, lead to different welfare implications depending on the structural parameters of an industry. Numerical simulations are provided to illustrate our findings     

EXPLAINING THE DISTRIBUTION OF QUOTA RENTS FROM US CHEESE IMPORTS

A theoretical model is outlined to illustrate how rents are generated from import quotas. The model is used to estimate rents from US cheese import quotas; rents are substantial. Relative rent capture by importers and exporters is explained by estimating an industrial organisation-type model. Unequal market power is important in explaining the distribution of rents between importers and exporters. Exporters tend to maintain price-cost margins and let importers capture a larger share as rent size increases.     

Welfare impacts of import controls on Botswana's horticulture

Botswana has, for the past two decades, used import controls (permits) to regulate horticultural imports, and thereby promote economic diversification through import substitution. This article estimates import demand equations to capture the impact of import controls on horticultural imports (oranges, potatoes, and onions) into Botswana, using data for 1974 to 2001. Parameter estimates are used to compute nominal protection rates (NPRs) and welfare effects. Model‐generated NPRs are estimated at 191%, 75%, and 109% for oranges, potatoes, and onions, respectively. Imports of oranges, potatoes, and onions declined by 32%, 29%, and 35%, respectively, due to the implementation of import controls. Over time consumer losses and quota rents rose while producer gains declined. Net social losses also increased, implying that import controls became increasingly burdensome. It is argued that import controls have not been very effective in promoting import substitution. The study is important for the trade liberalization debate in the Southern African Customs Union (SACU) and within the Southern African Development Community (SADC), where import permits and other nontariff barriers are pervasive, have proliferated, and are a major hindrance to intraregional trade.     

Modelling the Risks Associated with the Increased Importation of Fresh Produce from Emerging Supply Sources Outside the EU to the UK

The risk of non‐indigenous plant pests entering the UK via international trade in fresh produce is increasing. The objective of this article is to identify existing and emerging supply sources for UK fresh produce importers and examine the extent to which they could provide invasion pathways. We tested the hypothesis that increased imports of fresh produce from new sources outside the European Union could increase the risks of non‐indigenous insect pests. We use a bio‐economic model approach in which the number of species arrivals is a function of the volume of imports, whereas the volume of imports itself is a function of gross domestic product, relative import prices and seasonality. The study has identified clear trends, which show import volumes of fresh produce and species detections increasing from new supply sources. If this trend continues in the future, then the UK inspection agency should expect to confront species from new suppliers in much greater numbers, given that import volumes of fresh produce are income elastic.     

A Spatial Equilibrium Analysis of U.S.–Canadian Disputes on the World Softwood Lumber Market

This paper utilizes a world spatial equilibrium model to examine the effects of U.S.–Canadian softwood lumber disputes on U.S., Canadian, and other exporters' and importers' lumber markets. Results show that the U.S. import tariff on Canadian softwood lumber impacts prices, supply, demand and trade flows not only in the United States and Canada but also in the other countries. Though the goal of U.S. trade restriction is to limit imports from Canada and protect its producers, the United States cannot fully accomplish this goal as non-Canadian exporters fill the void left by the reduced imports from Canada. Canadian producers lose from the U.S. policy, but their loss is mitigated as Canada redirects its exports to other importers. Importing countries such as Japan and the European Union benefit from the U.S. trade restrictions as Canada seeks to sell its softwood lumber to these countries.     

Tariff quota administration in China's grain markets: An empirical assessment

In 2016, the U.S. launched a trade dispute against China at the World Trade Organization, arguing that China has been restricting its grain imports via tariff quota administration. Despite sharp criticisms by the U.S., the extent to which the grain imports were restricted in China remains largely unknown, primarily due to that China's grain import behaviors are still under-researched. The U.S. grain export sector might actually gain little from China's grain trade liberalization in the short run, since China has become less import dependent on the U.S. through the pursuit of import diversification. In this context, this article aims to quantify impacts of the tariff quota administration on China's grain imports from its trading partners. We calculate ad valorem tariff equivalents of the tariff quota administration and then estimate import demand elasticities using a source differentiated import demand model. We find that the tariff quota administration might have reduced China's quota fill rates for the grain commodities by 10–35% during 2013–2017. In particular, the U.S. wheat exports to China were largely negatively affected. We also find that the tariff quota administration in China acts like a variable import levy—its import restrictiveness varies negatively with world prices, leading to lower import demand elasticities.     

Brexit: How Will UK Agriculture Fare?

There is little doubt that Brexit would have significant implications for UK agriculture, a sector with strong trade links to the EU and strong reliance on CAP income support. This article reports preliminary results from employing a Computable General Equilibrium Model, a Partial Equilibrium Model and Farm Level Models to explore selected trade and domestic policy scenarios post‐Brexit. These allow for the estimation of changes in producer prices, production and farm incomes against a baseline scenario of continued EU membership. Under a Free Trade Agreement with the EU, agricultural impacts are relatively modest. By contrast, unilateral removal of import tariffs has significant negative impacts on prices, production and incomes. Adoption of the EU's WTO tariff schedule for all imports favours net importers (e.g. dairy) and harms net exporters (e.g. sheep). Given the strong dependence of most UK farms on direct payments, their removal worsens negative impacts of new trade arrangements and offsets positive impacts. Impacts vary across different types and sizes of farm, but also regionally. However, the period of adjustment to new trade and domestic policy conditions may prove very challenging for a large number of farm businesses.     

Enhancing food security in South Sudan: the role of markets and regional trade

South Sudan faces serious problems of food insecurity due to low levels of domestic food production, periodic droughts, widespread poverty, and since late 2013, renewed armed conflict. This article explores market price behavior using cointegration analysis and estimates the effects of production and trade shocks through multimarket model simulations. We show that market prices in the capital city, Juba, of both maize and sorghum are cointegrated with import parity prices of these cereals sourced from Uganda, consistent with observed trade flows. Model simulations, using econometrically estimated demand parameters, suggest that private sector imports of maize and wheat would greatly mitigate the potential fall in consumption in the case of a decline in domestic cereal production. Other simulations indicate that if total imports of cereals are reduced by one‐third (still more than two times the levels of food aid in 2013) because of disruptions to private market flows, domestic prices of cereals could rise by 45% or more. The article concludes that whatever measures are taken involving national food security reserves, it is crucial that government policy serves to maintain incentives for private sector imports to avoid destabilizing market supplies, domestic prices, and ultimately, food consumption of the poor.     

Dairy Tariff-Quota Liberalization: Contrasting Bilateral and Most Favored Nation Reform Options

A highly disaggregated, "tariff line," source-differentiated, partial equilibrium model of U.S. specialty cheese imports is developed to investigate reform options for tariff-rate quotas (TRQs). A mixed-complementarity framework is used to represent bilateral and most favored nation (MFN) tariff quotas. The impacts of liberalizing U.S. specialty cheese imports via bilateral and MFN quota expansions, out-of-quota tariff cuts, and simultaneous liberalization scenarios are evaluated. We find that the path of liberalization is quite different, depending on the reform approach undertaken, particularly if the United States adopted an MFN quota administration mechanism for specialty cheese imports.     

Crisis Behind Closed Doors: Global Food Crisis and Local Hunger

The high and volatile food prices in 2007–8 triggered estimates of massive increases in poverty and hunger. However, hunger and volatile food prices have long been a feature of developing economies. This paper examines the impact of high global food prices on domestic terms‐of‐trade, food consumption and child undernutrition in the Central African Republic, Ethiopia, Liberia and Sierra Leone, comparing findings with the impacts of ‘seasonality’. As high international food prices permeated domestic markets, households in all the case study areas resorted to coping strategies common in the annual hunger season. Though acute malnutrition has not risen as consistently as in a seasonal hunger crisis, reduced micronutrient intake threatens to have severe long‐term consequences for health and poverty reduction. The similar impacts of seasonal and global food price rises on households provide an opportunity to design appropriate interventions to protect livelihoods.     

Trends in global virtual land trade in relation to agricultural products

Trade volume of agricultural products can be used to quantify the virtual land transfers between countries. This study assessed the virtual land trade (VLT) associated with the global trade of agricultural products using specific crop yield of exporting countries and gave insights in characteristics of different products and different countries. In addition, the features of trade connections were also displayed by network analysis. The results showed that the total virtual land within global agricultural trade increased from 128 million hectare (ha) in 1986 to 350 million ha in 2016, the average annual growth rate was 5.73 %. Increases in trade of oil crops contributed the largest share to this. The proportion of exported land area in total harvested land area increased for almost all categories of agricultural products. Countries engaged in global agricultural trade could be divided into three groups, net exporters, net importers and countries with balanced VLT. The net importers could be further divided into the countries with absolutely scarce land resources and the countries with relative scarce resources. All net virtual land exporters are the countries with more land resources per capita, such as the United States, Brazil and Argentina. Income growth and changes in diet structure are main factors driving increases in VLT. The VLT network became more complex over the study period, with the number of import and export nodes increasing continuously, and the cumulative distributions of export and import node strength following power law distributions. The major links and players within national, geographic, and economic groups also changed significantly over the study period. VLT has a deep impact on society, economy and environment, appropriate policies should be taken to make these interlinkages more sustainable for both importers and exporters.     

The Equivalence of Tariffs and Quotas under a Tariff‐Rate Quota System: A Case Study of Rice

This study examines the effect of tariff‐rate quota (TRQ) expansions as have emerged from the international trade negotiations that are designed to ensure market access for many sensitive agricultural products. We extend the existing models on tariff–quota equivalence to a TRQ system. Our theoretical finding indicates that the equivalence of domestic price between out‐quota tariff reduction and quota expansion depends on domestic producer's behavior and on the values of conjectural variation. An empirical spatial equilibrium model of international rice trade is used to examine the price and welfare impacts of replacing quota expansions with tariff reductions. Le présent article examine les répercussions de l’expansion des contingents tarifaires issue des négociations de commerce international pour assurer l’accès au marché de nombreux produits agricoles sensibles. Nous avons élargi les modèles existants d’équivalence entre les quotas et les tarifs à un système de contingents tarifaires. Nos résultats théoriques ont indiqué que l’équivalence de prix intérieur entre la diminution des tarifs hors contingent et l’expansion des contingents dépend du comportement du producteur national et de la valeur des variations conjecturales. Nous avons appliqué un modèle empirique d’équilibre spatial dans le commerce international du riz pour examiner les répercussions du remplacement de l’expansion des quotas par des réductions de tarifs sur le prix et le bien‐être.     

Asset Pricing in Created Markets

We investigate the applicability of the present-value asset pricing model to fishing quota markets by applying instrumental variable panel data estimation techniques to 15 years of market transactions from New Zealand's individual transferable quota (ITQ) market. In addition to the influence of current fishing rents, we explore the effect of market interest rates, risk, and expected changes in future rents on quota asset prices. The results indicate that quota asset prices are positively related to declines in interest rates, lower levels of risk, expected increases in future fish prices, and expected cost reductions from rationalization under the quota system.     

Evaluating the TRQ Import Licensing Mechanisms in the Canadian Chicken Industry

Tariff rate quotas (TRQs) were introduced at the end of the Uruguay Round to support market access following the tariffication of nontariff barriers to trade in agriculture. The allocation of import licenses under the TRQ regime in the Canadian chicken industry is currently made according to discretionary criteria. The welfare properties of this import licensing scheme are evaluated in comparison with a less discretionary allocation method such as first-come, first-served (FCFS) using a numerical model. The analysis also provides a welfare evaluation of both methods as the current minimum access commitment for chicken imports is expanded. It is found that total welfare in the Canadian chicken industry is likely to be higher under a TRQ administration method based on nondiscretionary criteria such as firstcome, first-served. However, particular assumptions about the chicken producers'response to increased foreign competition can reverse this finding. Moreover the welfare differences between the two license administration schemes are less important when market access to imports is substantial.     

Impacts of Trade and Agricultural Policies on the World Malt and Malting Barley Market

Major changes have been occurring in agricultural policies affecting world malt and malting barley production and trade. This paper analyzes effects of these changes on international trade and competition. A spatially disaggregated linear programing model of the world malt and malting barley sector is constructed and used to analyze effects of changes in European Union supply, European Union restitutions, the U.S. Export Enhancement Program subsidy regime, and import tariffs on malt and malting barley. Policy changes are found to generate substantial changes in trade flows and competitiveness between producing and exporting regions.     

Japan's peanut import demand: implications for United States exports

Japan's import demand for both raw peanuts and processed peanut products was estimated using the Rotterdam model in order to determine the impact of an increase in the Japanese raw peanut quota on peanut imports from the USA and its competitors. The results indicate that if a larger import budget were allocated to raw peanut imports by Japan, most of the increase would be allocated to imports of Chinese raw peanuts. Furthermore, U.S. exports of peanut products could be affected if Japanese expenditures on peanut product imports change as a result of an increase in the quota for raw peanut imports. Thus, this study concludes that an increase in the Japanese import quota for raw peanuts provides only limited market opportunity for U.S. peanut exports, and China appears to benefit more than the USA from an increase in the Japanese raw peanut import quota. In contrast, the value added trade of peanut products could provide a better market opportunity for the U.S. peanut industry.
