Regional trade agreements and trade in agri-food products: evidence for the European Union from gravity modeling using disaggregated data

The proliferation of regional trade agreements in recent years has intensified the debate on the desirability of these agreements in themselves and their coexistence with multilateral free trade under the WTO. This study contributes to this debate by analyzing trade creation and trade diversion effects of the European Union on trade flows of six major agri‐food products from 1985 to 2000. An extended gravity model is estimated employing pooled data and generalized least squares methods. The results show that the developments in the EU since the mid‐1980s have served to boost agri‐food trade significantly among the members. Some of the growth in intra‐EU trade in agri‐food products came at the expense of nonmembers as the EU reduced the degree of relative openness to trade with nonmembers during this period and diverted trade from the rest of the world into the intra‐EU channels.     

The impact of EU trade preferences on the extensive and intensive margins of agricultural and food products

In this article, we study the trade creation effects of EU preferential trade agreements (PTAs) in the agriculture and food sectors for a large sample of developing countries in the period 1990–2006. We investigate the extent to which the PTAs affect trade through the extensive margin—number of exported products—or the intensive margin—volume of existing products. We use a gravity framework in a panel data setting, and different estimators to deal with the issues of zero trade flows and the presence of an upper bound in the dependent variable. The results show that EU PTAs positively affect the extensive margin in agricultural trade, but not in processed foods. As regards the intensive margin, the effect is driven by the role of tariffs alone, whereas the other provisions of PTAs do not exert any other significant impact on agricultural or food products.     

Assessing agricultural trade policies options with the European Union: a Brazilian perspective

Brazil has shown interest in agricultural trade negotiations at bilateral, regional, and multilateral levels. This study addresses several important negotiations, using the agricultural sector model CAPRI (Common Agricultural Policy Regional Impact Analysis), to analyze liberalization scenarios between the European Union and the Mercosur countries focusing particularly on their impacts in Brazil. Four possible agreements between Europe and Mercosur are simulated, including a broader multilateral agreement proposed in the G20. The results suggest that a bilateral scenario involving larger tariff rate quota increase, as called for by Mercosur, generates larger gains than accepting the European Union proposal of 2004 or further multilateral trade liberalization based on the G20 proposal. However, much larger increases in tariff rate quotas for all products are not necessarily justified in all cases. Moreover, Brazil's production and export potential is limited by factors other than trade restrictions.     

Explaining National Border Effects in the QUAD Food Trade

Using a ‘structural’ gravity‐like model, this paper first provides estimates of bilateral ‘border effects’ in food trade among the QUAD countries (the US, Canada, Japan and the EU) at the ISIC (International Standard Industrial Classification) four‐digit level (18 food sectors). It then investigates the underlying reasons for border effect, assessing the role played by policy barriers (tariffs, non‐tariff barriers to trade (NTBs) and domestic support) with respect to barriers unrelated to trade policy, such as information‐related costs, cultural proximity and preferences. In contrast to several previous findings, our results show that policy trade barriers, especially in the form of NTBs, are part of the story in explaining national border effects. Interestingly, in all country pair combinations, NTBs significantly dominate the trade reduction effect induced by tariffs. However, results show that elements linked to information‐related costs and consumer preferences matter a great deal in explaining the magnitude of border effects. These findings have implications for the economic and welfare‐related significance of national borders.     

Economics and politics of food standards,trade, and development#

Standards have played an important role in food trade for a very long time. Their rapid growth in recent years has triggered vigorous debates on their impacts on international trade and development, with many arguing that standards are “non‐tariff barriers” to trade and that standards are marginalizing the poor. I present conceptual frameworks and review empirical evidence on the equity and efficiency effects and the political economy of standards. Models which incorporate essential aspects of standards yield complex theoretical results and nuanced conclusions. Careful empirical analyses support such nuanced arguments and find complex effects. For trade, standards can create welfare gains but also involve rent redistribution which induces lobbying by interest groups to set the standards at their preferred level. This makes it difficult to distinguish socially desirable standards from those resulting from political rent‐seeking. For development, it is crucial to explicitly account for (a) the endogeneity of the institutional organization of value chains and (b) both smallholder contracting and employment creation on large scale farms when considering the impact of standards on development and poverty.     

Trade Creation and Diversion Effects of Preferential Trade Associations on Agricultural and Food Trade

Agricultural market distortions remain a major focus of contention in world trade negotiations. Estimates of the effects of liberalising current agricultural trade restrictions indicate an approximately $385 billion increase in global welfare, with the disproportionate share of the benefit being enjoyed by developing countries. In response to difficulties in adopting agricultural trade reforms, individual groups of countries have formed multiple bilateral and regional preferential trade agreements (PTA) to enhance trade among members. Few sectoral analyses exist of the effects on agricultural and food product trade of PTAs. This research uses a gravity model to isolate the effects of various PTAs on both intra‐ and extra‐bloc agricultural and food product trade for three time periods: 1995, 2000 and 2004. Findings strongly support PTA benefits in terms of increased intra‐bloc trade in both sectors. The findings also generally support trade creation in agricultural products. PTA membership was also associated with food trade creation in most cases, although diversion was observed for several associations composed primarily of developing countries.     

Re‐evaluating the Harbinson Proposal – Prospects for the EU25: A Note

In this study, we use the Harbinson Proposal and July Framework to compare a ‘likely’ Doha scenario with a realistic baseline. The novelty of this study is that we focus exclusively on the trade‐led welfare impacts in selected EU member states. The important features of this note are the: (i) usage of the latest Global Trade Analysis Project (version 6) data; (ii) focus on EU25 regions incorporating all major Common Agricultural Policy instruments and reforms; and (iii) inclusion of binding tariff overhangs into the Harbinson tariff reductions. Results show the damping effects of tariff‐binding overhangs on welfare outcomes. This and other factors which limit the gains to liberalisation mean that the EU25 only realises 10% of its long‐run welfare gain potential, as defined by complete liberalisation.     

A trait-based model of the potential demand for a genetically engineered food crop in a developing economy

We predict the potential demand of smallholder farmers for genetically transformed varieties of a food crop, the cooking banana of the East African highlands. Farmer demand for planting material is derived in an agricultural household model that accounts for variety traits and missing markets. The demand for candidate host varieties is predicted using a Zero‐Inflated Poisson (ZIP) regression system. The fitted model is used to illustrate the sensitivity of farmer demand for improved planting material to (a) investments in research and development, represented by the effectiveness of gene insertion and expression, and (b) other public investments in education, extension, and market infrastructure that support diffusion. By comparing the characteristics of agricultural households we demonstrate that the choice of host variety can have social consequences, favoring one rural population compared with another. Clients for transgenic banana planting material are likely to be poorer, subsistence‐oriented farmers in areas greatly affected by biotic constraints. A model of this type might be useful in assessing the investments needed to support the systematic dissemination of improved planting material. The approach can be generalized to other crop biotechnologies for smallholder farming systems, particularly in developing economies.     

Canada's beef exports: Border effects and prospects for market access

This paper examines the magnitudes of border effects on Canada's beef exports, and assesses the prospects for market access. The empirical analysis relies on a gravity model derived from a supply-based framework, and implements different econometric methodologies. It covers the conventional measurement of border effects that is determined relative to the intranational trade baseline. Also, it sets alternative baselines to estimate the wedge between the border effects on beef exports of Canada and those of other countries. The estimated parameters are used to carry out different scenarios to examine the tariff-related and nontariff border effects, and to evaluate the impacts of trade preferences for Canada's bilateral beef exports. The results reveal significant trade impediments facing Canada's bilateral beef exports to many large markets (e.g., EU-15, Japan, Republic of Korea, China, and Russia), and they often indicate that the effects of tariff reductions become considerably larger when coupled with reductions in nontariff impediments. Also, they underscore the significance of North American Free Trade Agreement (NAFTA)’s preferential market access for Canada's beef exports. The export opportunities for the Canadian beef industry that are generated through lower trade barriers would, however, decrease when trade barriers facing other beef-exporting countries are reduced.     

Determinants of a social clause in international trade negotiations

Survey data are used to examine the determinants of a “social clause” in international trade negotiations. Proponents of such a clause argue that the inclusion of labor laws, environmental impacts, and other social issues in international trade negotiations would ensure fair competition, an equitable distribution of the benefits of free trade, and, in the case of labor, protect the basic rights of workers. Opponents see these arguments as a disguised form of protectionism and self‐interest based on the protection of labor‐intensive industries in developed countries. Results from a logit model indicate a decreased likelihood for the inclusion of a social clause in international trade negotiations across farm sizes. In particular the results suggest that agricultural producers with annual gross sales including government payments between US$500,000 and US$999,000, are 40% less likely to want labor laws, environmental impacts, and food safety standards to be included as part of international trade negotiations. The results also show that agricultural producers with college experience or college degrees are less likely to want these social interventions while second generation farmers and first generation farmers with a master's degree want labor laws, environmental impacts, and food safety standards to be included as part of international trade negotiations.     

Trade Elasticity,Gravity and Trade Liberalisation: Evidence from the Food Industry

We present an econometric investigation of the trade effect produced by the elimination of tariffs in 18 food sectors for a large sample of developing and developed countries. The standard CES monopolistic competition trade model and the gravity equation were used to estimate trade substitution elasticities, exploring their sensitivity to different estimation methods. Using these elasticities, we simulate the trade effect of the elimination of tariffs, dealing with the problem of uncertainty in the estimated values. Results point to a significant variation in the elasticities estimated by different econometric methods, suggesting that the Poisson pseudo‐maximum‐likelihood estimator significantly inflates their magnitude. Simulation results indicate that trade liberalisation will strongly increase food exports especially from high income and emerging countries, leading to a general loss of market share by developing countries. The simulated trade flows obtained from the econometric approach are quite close to current evidence based on computable general equilibrium models.     

Exporting to new destinations and the effects of tariffs: the case of meat commodities

This study uses a random parameter probit estimation to examine the effects of tariff liberalization on the probability of establishing new trading relationships in meat commodities. Our simulation results indicate that the effects of tariff reductions decrease with distance, but increase with the level of development. The probabilities of trade increase at an increasing rate with the size of tariff reductions thus justifying calls for ambitious liberalization schemes. Canada and Mexico are the NAFTA countries that are most likely to export in response to EU tariff reductions on bovine and poultry meats, while Brazil and Argentina emerge as the MERCOSUR countries most likely to penetrate the EU bovine meat market after EU tariff reductions. Uruguay's probability to export poultry meat is most responsive to EU tariff reductions.     

Drivers of vertical intra‐industry trade: the case of the Hungarian agri‐food sector

This article investigates the drivers of vertical intra‐industry trade (VIIT) in Hungarian agri‐food trade with the European Union (EU). It identifies three possible ways to measure intra‐industry trade (IIT) flows (GHM, FF, and N methods) and defines six hypotheses to test for the drivers of VIIT with three panel data models (static, dynamic, and FEVD). The results suggest that factor endowments are negatively, while economic size is positively and significantly related to VIIT. Distance and VIIT were found to be negatively related as is commonly the case in the standard gravity model. It was also found that VIIT is greater if a New Member State (NMS) is exporting agri‐food produce to an NMS, while EU accession has ambiguously influenced the share of VIIT. In general, it seems that our results are independent from model estimations and interestingly they do not differ considerably as we a priori expected. Moreover, our results seem surprisingly robust across various measurements of ITT.     

How important are tariffs and nontariff barriers in international markets for fresh fruit?

International markets for agricultural products are often subject to a range of trade barriers, and horticultural products are no exception. This article examines the economic implications of tariffs and sanitary and phytosanitary (SPS) regulations that are applied to global markets for fresh apples and fresh oranges. We calculate regional‐level tariff rates and ad valorem equivalents for SPS barriers following the price‐wedge approach. A simulation model is developed and used to assess the price, quantity, and welfare implications of reducing tariffs, removing SPS barriers, and removing SPS barriers that have been identified as a Specific Trade Concern (STC) by the World Trade Organization. Results suggest that a 36% reduction in global tariffs would lead to greater welfare gains than would the elimination of SPS measures in apple markets. However, in orange markets, we find that SPS measures have much larger economic implications for producers and consumers. Here, a 36% reduction in tariffs would lead to smaller overall welfare effects compared to removal of all SPS measures, and only slightly larger effects than those from removal of STCs alone.     

Economies of scale and market structure in international grain trade

A large body of literature has examined international grain trade in imperfectly competitive models. The article develops a two-stage duopoly model that considers a private trader and a State Trading Enterprise (STE) competing on a foreign market. The key difference between the private trader and the STE is their international organization; while the STE makes use of external agents to export, the private firm may choose to internalize international transactions. The game is solved for different modes of competition and under both assumptions of homogeneous and differentiated products, in order to assess how these assumptions affect the outcome of the game. The results of the game are examined by using numerical examples. The analysis shows that external shocks on export markets may result in a change of market structure and, consequently, of market shares. These effects depend on the initial market structure. Furthermore, the degree of product differentiation and the assumed mode of competition significantly affect the relative values of transaction and fixed costs at which the market structure changes.     

Disaggregated trade and disaggregated currency unions: a ranking of common currency effects

Andrew Rose has long argued that a common currency has a large effect on increasing trade. Recently, Rose has called into question the reliability of this conclusion, as new techniques have emerged for estimating gravity equations. This article uses the sector‐specific gravity model developed by Anderson and Yotov (2010a) to investigate if disaggregated trade can provide a reliable estimate of a common currency's effect. Disaggregating trade alone is insufficient to obtain a reliable estimate of a currency union, regardless of econometric technique, when the effect of a common currency on trade is uniform across all unions. Disaggregating the universe of currency unions with individual effects provides a reliable ranking of currency unions, independent of estimation method, by the effect that each union's currency has on increasing trade. These rankings differ across sectors.     

Agricultural trade liberalization and economic development: the role of downstream market power

A model is developed to characterize the vertically linked and concentrated nature of developed‐country food markets. This model is then parameterized and used to simulate the effects of varying food market structures on the benefits to developing‐country exporters of agricultural commodities from trade liberalization by developed countries. Results demonstrate that even relatively modest departures from perfect competition can cause much of the benefits from trade liberalization to flow to marketing firms instead of producers in the developing country. The distributional effects under downstream market power differ significantly from the perfectly competitive case and may result, somewhat paradoxically, in developing countries receiving a lower share of the total value added within the food chain as trade reform occurs.     

The costs of global tariff barriers on wool products: 1997–2005

The Doha round of multilateral trade negotiations commits World Trade Organization (WTO) members to improving market access for both agricultural and nonagricultural goods. Tariff barriers on wool products represent a small but important subset of these negotiations. To inform the debate on the round, we analyze the distortionary effects of recent (1997–2005) tariff barriers on wool products using a model that applies a comprehensive analytical approach with regard to the production, trade, and consumption of wool products. We also account for any indirect effects of wool tariff barriers on the nonwool economy by incorporating the production, trade, and consumption of nonwool products, that is, the framework is a comparative‐static global general equilibrium model with a detailed representation of the world wool market. Changes in wool tariffs over 1997–2005 lead to positive welfare effects for most regions; Italy, China, and the UK are estimated to have gained the most from the changes. The results indicate that the nature of recent wool tariffs severely distort the size of wool industries in different regions. The changes in the output of wool commodities are extreme reflecting the discriminatory nature of the tariffs.     

US—Mexico fresh vegetable trade: the effects of trade liberalization and economic growth

Studies of US‐Mexico vegetable trade have generally emphasized the importance of US tariffs in determining the competitive advantage of US producers. Even so, research has identified at least four factors related primarily to the different levels of economic development in the US and Mexico that also have important effects on US‐Mexico agricultural trade in general and fresh vegetable trade in particular. These include the differential growth rates of US and Mexican real wages, production technology (yields), and per capita income as well as cyclical movements in the real Mexican Peso/US Dollar exchange rate. This study examines the relative contribution of NAFTA and the development‐related factors to likely future changes in US fresh vegetable imports from Mexico. The analysis employs an econometric simulation model of US and Mexican markets for five fresh vegetables (tomatoes, cucumbers, squash, bell peppers, and onions) accounting for 80% of US fresh vegetable imports. The results suggest that the 1994–1995 Peso devaluation rather than NAFTA was primarily responsible for the sharp increase in US imports of Mexican vegetables observed in the first years following the implementation of NAFTA. Over time, however, the results suggest that differences in the growth rates of US and Mexican production yields and, to a lesser extent, of US and Mexican real incomes and/or real wage rates could plausibly contribute more to the future growth of US tomato, squash, and onion imports from Mexico than the trade liberalizing effects of NAFTA.     

The role of intellectual property rights in seed technology transfer through trade: evidence from U.S. field crop seed exports

A panel of 134 countries over the period 1985–2010 is used to evaluate the effect of intellectual property rights (IPRs) on field crop seed imports from the United States. Based on estimating a gravity equation using the Heckman selection and Poisson fixed‐effects panel econometric methods, the results indicate that membership of countries in both the International Union for the Protection of New Varieties of Plants and the Trade‐Related Aspects of Intellectual Property Rights Agreement of the World Trade Organization have a positive and statistically significant effect on their imports of U.S. field crop seeds. These results, however, are also sensitive to both income level of importing countries and better enforcement of IPRs by those countries.
