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.     

The Impact of Regulations on Agricultural Trade: Evidence from the SPS and TBT Agreements

According to World Trade Organization rules, countries may adopt regulations under the Agreements on Sanitary and Phyto-Sanitary (SPS) and Technical Barriers to Trade (TBT). We analyze the structure of these measures in agricultural trade. The inventory approach suggests that European countries have among the lowest coverage ratios of all OECD countries. Using a gravity equation, we also estimate their stringency. Our results suggest that they significantly reduce developing countries' exports to OECD countries, but do not affect trade between OECD members. Furthermore, European imports are more negatively influenced by SPS and TBTs than imports of other OECD countries.     

Trade,policy, and food security

Food insecurity is extensive throughout the world and hunger and malnutrition are expected to remain serious humanitarian and political concerns, both in the short term and for the foreseeable future, particularly in low income developing countries where many rural and urban households are both income and asset poor. In those countries, domestic agricultural production is expected to be especially vulnerable to the impacts of climate change over the next 30 years. Thus international markets for staple agricultural commodities, which have become increasingly important as sources of nutrition for both developing and developed countries over the past 60 years, are likely to become even more important in the future. Free trade policies allow countries to exploit their comparative advantages in economic activity, increasing average per capita incomes, longer term growth rates and a country's capacity to fund social safety nets for the poor. However, many countries abandoned those policies in favor of domestic protections in their efforts to mitigate the effects of short run food crises. The policy challenge is therefore to resolve the tension between optimal long run policies and short run initiatives to address food security concerns.

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.     

Bilateral Import Protection,Free Trade Agreements,and Other Factors Influencing Trade Flows in Agriculture and Clothing

Many factors shape the global network of bilateral trade including fundamental forces of supply and demand factors and government policies. This study uses the generalised gravity framework to distinguish among the different drivers that either deter or aid partner trade in land‐intensive agriculture and labour‐intensive clothing. The dataset used in the analysis includes bilateral trade among 70 countries in 1995, 2000 and 2005. Collectively, the 70 countries account for 85% of the world’s trade in agriculture and 96% of its GDP. Empirical results lend support to the Heckscher–Ohlin explanation of trade, namely that relative factor endowments motivate cross‐border trade. Results also show that tariffs are not always binding and bilateral free‐trade agreements more often divert rather than create trade.     

Farm Size,Technology Adoption and Agricultural Trade Reform: Evidence from Canada

Using detailed census data covering over 30,000 farms in Alberta, Saskatchewan and Manitoba, Canada, we document the vast and increasing farm size heterogeneity, and analyse the role of farm size in adapting to the removal of an export subsidy in 1995. Consistent with the Alchian-Allen hypothesis, the increase in per-unit trade costs due to the reform was associated with farms of all sizes shifting their production of crops from low value wheat to higher value canola. We find that switching to new labour-saving tillage technologies and away from summerfallow in response to the large negative shock to grain prices caused by the reform varied across the farm size distribution. We develop a theory of heterogenous farms and technology adoption that can explain our findings.     

Trade diversion and antidumping effectiveness: insights from a residual demand model

A residual demand model is developed to predict the likely effects of an antidumping duty in the presence of trade diversion. A key insight is that the ability of an AD duty to increase the welfare of producers in the country imposing the duty hinges on the import supply elasticity for product from non‐named sources. The only instance in which this is not true is when supply for product from the named source is perfectly elastic. In this case, the welfare gain to domestic producers is maximised irrespective of the supply elasticity for imports from non‐named sources. A comparison of the residual demand model with the Armington model suggests the latter significantly understates both trade diversion and domestic producer gains from the duty.     

The Effects of Non‐tariff Measures on Agri‐food Trade: A Review and Meta‐analysis of Empirical Evidence

The increasing policy interest and academic debates on non‐tariff measures (NTMs) has stimulated a growing literature on how NTMs affect agri‐food trade. The empirical literature provides contrasting and heterogeneous evidence, with some studies supporting the ‘standards as catalysts’ view, and others favouring the ‘standards as barriers’ explanation. To the extent that NTMs can influence trade, understanding the prevailing effect, and the motivations behind one effect or the other, is a pressing issue. We review a large body of empirical evidence on the effect of NTMs on agri‐food trade and conduct a meta‐analysis to disentangle potential determinants of heterogeneity in estimates. Our findings show the role played by the publication process and by study‐specific assumptions. Some characteristics of the studies are correlated with positive significant estimates, others covary with negative significant estimates. Overall, we found that the effects of NTMs vary across types of NTM, proxies used for NTMs, and levels of detail of studies. The estimated effects are also influenced by methodological issues and publication processes.

Potential Impacts of Transatlantic Trade and Investment Partnership (T-TIP) on the Fresh Vegetable and Beef Trade

ABSTRACT

The Transatlantic Trade and Investment Partnership (T-TIP) negotiations influence the global economic position of both the European Union (EU) and the United States (U.S.). Agricultural issues are an important part of the negotiation. There have been several analyses of the aggregate impacts of a T-TIP agreement. This report analyzes the commodity impacts on trade for fresh vegetables and beef. Vegetables represent the situation where the U.S. is a growing net importer and the EU has substantial potential for expanding exports to the U.S. in this highly competitive marketplace. Beef represents the situation where sanitary and phytosanitary restrictions on hormone use in production have prohibited consumer choices from being revealed in the marketplace for both the EU and the U.S. The authors provide insight into where the comparative advantages lie in freer trade situations.

中美贸易战对林产品贸易的影响及其对策建议

在梳理中美林产品贸易相互关系的基础上,分析了新一轮贸易战将对中美林业产业、林产品贸易、就业等的影响。结果表明:贸易战对中低级技术水平的从业人员影响较大,短期内对中国传统优势产品出口冲击较大,但长期反而能分摊和降低贸易风险,以价格优势为主的微利型木材加工企业和以美国为主要出口市场的出口导向型企业将面临较大风险;同时,贸易战不仅会直接损害美国消费者利益,还会加速其木材产业的萎缩。拓宽进口渠道,扩展替代市场和国内市场,加快国际合作,加强技术创新,落实财政政策是中国减缓和避免贸易战对中美双方林产品贸易产生不利影响的应对措施。     

Patent Rights and Trade: Analysis of Biological Products, Medicinals and Botanicals, and Pharmaceuticals

This article analyzes the effects of foreign patent rights on U.S. bilateral exports. The empirical analysis covers three highly disaggregated drug industries over three decades. We estimate bilateral trade equations for each industry using cross-country data on the strength of national patent rights. The findings show that strong foreign patent rights enhance the market power of U.S. drug exporters across countries with weak imitative abilities. Alternatively, strong foreign patent rights stimulate the market expansion of U.S. drug exports across countries with strong imitative abilities. These effects are larger in magnitude during the 1980–90s relative to the 1970s.     

Trade Liberalization,State Trader Management Tenure,and Grain Pricing in Botswana

This article examines how trade liberalization and grain marketing board management tenure influenced grain pricing in Botswana. Regression analyses of nominal protection rates (NPRs) and marketing margins (MMs) are used to test the hypothesis that policy reforms influenced grain pricing in the country. Moreover, a comparison of NPRs is undertaken to determine whether management tenure has had an influence on grain pricing. The results indicate that the marketing board switched from taxing to subsidizing consumers following the 1991 policy reform from food self-sufficiency to food security. A reversal occurred after the board's 1997 restructuring, which involved, among other things, closing down Botswana Agricultural Marketing Board's (BAMB's) loss-making units and a change in the composition of BAMB's board of directors. Management tenure at BAMB also had an influence on grain pricing. The period 1989–1997, in particular, was characterized by high consumer subsidization, highest marketing margins, and lowest profits. This could have been avoided had management adopted pricing regime consistent with public policy. This notwithstanding, perennial losses experienced by the marketing board also resulted from fragmented production and low producer market participation.

贸易受益与汇率

多数教科书的相关理论都暗含着这样一个假设：汇率决定贸易受益的分配，而不是贸易受益的绝对水平。由于汇率不影响一国的相对价格，因此贸易结构和相应的贸易受益也不受影响。然而，汇率确实影响贸易条件和受益的分配，但相反却是中性的。本文将运用一个简单的两国、两种商品模型来说明贸易受益的分配（以国内货币计算）取决于发起贸易的国家。如果没有一个国家发起贸易，那么贸易受益则只意味着汇率。考虑到货币可兑换性，贸易结构将潜在地受到影响，货币的流动可能充当第三种“转移”商品的作用。由于外国货币都有一定的国内价值，在贸易框架内它就成为第三种商品，贸易受益就可能超过简单的两种商品、两个国家的情况。有趣的是，在货币可兑换的情况下，两种商品模型中的隐形汇率和双边贸易是不一致的。最后，本文认为文中建立的简单模型说明了汇率并不能平衡通货（或转移商品）的流动，同时仍然保留着可兑换性。
