Non Technical Summary
The effects of food safety scares are part of a dynamic process, where consumers change consumption during the scare and often return to their past behavior afterward. The dynamics of consumers' perception of food safety scares are interesting and important to capture because of their strategic implications for the supply chain management. A safe food supply is arguably one of the most important factors in a society's health and success. Safe food production, transportation, distribution and handling are all paramount to gaining and keeping consumers' trust. A key question regarding consumers and producers is how they react when faced with unexpected food safety shocks. Recently, there have been many food safety outbreaks in the processed beef and other meats such as pork and poultry, as well as seafood products, fresh produce such as lettuce, spinach, cucumber, and others. Prior to this, concern was about Bovine Spongiform Encephalopathy (BSE) discovery and Foot-and-Mouth Disease (FMD) outbreaks that received worldwide attention and reporting. This project will explore producers and consumers' reactions and responses to food safety incidents. Better understanding of market reactions to food safety scares helps protect the loss from such incidents.

Goals / Objectives
1. To investigate the dynamic responses of consumers to the impact of food safety incidents, evidenced and measured by changes in their purchasing decisions in the temporal neighborhood of food safety events. A key question regarding consumer behavior is how consumers react when faced with unexpected food safety scares and whether consumer responses to sudden, unanticipated safety concerns are consistent with rational well-informed consumer behavior. There is a great deal of concern over food safety shocks and their related regulations and standards associated with market exchange of agricultural products aiming at reducing the spread of pests and diseases and mitigating foodborne illnesses. Better understanding of consumer reactions to food safety scares helps the food industries restore consumer confidence after food safety crises and provides opportunities for national-level production differentiation based on food safety and quality. 2. To explore the impacts of food safety events on monopolistically competitive farms and firms in the food industries. There are economic losses associated with food safety incidents in the form of food recalls, loss of consumer confidence in the food supply channels, and loss of markets. Producers and processors need to be prepared for low-probability events that can have large detrimental impacts. Investments that can be made to lower the large losses from an unlikely event seem to be justified. Proactive information provision in the food marketing systems reduces the impacts of the food scare. Producers and retailers can promote branded food products with emphasis on variety and quality to differentiate themselves from competitors and gain competitive advantage over rivals. Marketing food safety and quality as an attribute and using quality assurance labels for food products effectively restore consumer confidence as well as potentially create niche markets to increase both producer and consumer surplus. 3. To investigate the market impact of food safety scares on food sectors by focusing on the short-run and long-run dynamics of price adjustment and price transmission along the marketing channels of food products to see how food safety scares affect the price margins at the farm, wholesale, and retail levels. These issues are often considered to be relevant to structure, conduct, and performance issues (i.e., market power). Market concentration and imperfect competition can be the cause of asymmetric price transmission. Price asymmetry may reflect asymmetries in underlying costs of adjustment, or may reflect government intervention effects. Defining the extent of a market is also used for anti-trust considerations. 4. To investigate the strategic responses of producers, marketing managers, and retailers to food safety incidents. Better understanding of marketing channels and consumer reactions to food safety scares helps the food industries construct strategies that restore consumer confidence after food safety crises, with emphasis on enforcement of public and private regulations, traceability, product differentiation, packaging, labeling, and provision of food safety assurance as a quality attribute.
Project Methods
The impact of food safety scares has been extensively investigated in the literature. Scientific methods applied to food safety events have a wide range from most commonly used models of Almost Ideal Demand System, the Rotterdam models and their different variations, to models of contingent valuation, experimental auction and conjoint analysis (e.g., Marsh, Schroeder and Mintert, 2004; Piggott and Marsh, 2004; McCluskey, et al., 2004; Peterson and Chen, 2005; Livanis and Moss, 2005; and Chopra and Bessler, 2005). These models, however, are not quite appropriate to investigate the short- and long-run dynamics of farm, wholesale and retail-level changes, and consumer reactions to sudden food safety events in the neighborhood of food safety events as reflected in the actual data, which are the main goals of the first two objectives. In cases where actual data do not exist, contingent valuation and other non-market valuation techniques are widely used. In cases where high frequency retail price and quantity series are available, one can use contemporary time-series analyses, namely, cointegrated vector error correction (VEC) models, directed acyclic graphs, and historical decomposition graphs to investigate consumer responses to sudden, unexpected food safety scares (Saghaian, Maynard, and Reed, 2006). These techniques result in a more accurate estimation of the complex interrelated effects among the variables under study. Directed graphs, in particular, allow the errors among the endogenous variables to be incorporated into the forecasted effects of the market shocks over time. We can trace the dynamic effects of the market shocks on farm, wholesale and retail-level prices and quantities over time to see if these changes are consistent with well-informed rational consumer behavior, evaluate price transmission along the supply channel, investigate speeds of adjustment and market integration, or examine potential differential impacts of the shocks along the marketing channels. The VEC model will not only allow estimates of short-run relationships for the price and quantity series, but it also preserves the long-run relationships among the variables. Cointegration binds the series into a long-run relationship; it is now commonplace to examine time-series variables by cointegration techniques. Historical decomposition aids in providing a visual explanation of the impact of the beef safety shock on the price and quantity series in the neighborhood of each event. Specifically, orthogonal innovations are constructed using graph theory to determine causal patterns behind the correlation in contemporaneous innovations of the VEC model.

Impacts
What was accomplished under these goals? We investigated food safety regulations and international trade of agricultural products with three aspects: the signalling effect from U.S. strict food safety regulations on U.S. vegetable exports, political determinants of sanitary and photosanitary non-tariff barriers, and the impact of trade barriers on employment in developing countries. First, we investigated the impact of high U.S. maximum residue limit (MRL) standards on U.S vegetable exports to 102 countries utilizing the hierarchical model. MRL, which is one of the non-tariff barriers with respect to food safety, is applied to home and foreign countries at the same time. Thus, firms in countries with higher food safety standards are expected to have a competitive advantage from the 'signalling/learning effect'. The results show that high MRL standards in the U.S. have a positive impact on U.S. vegetable exports, indicating the 'signalling effect' from the strict U.S. domestic MRL standards. The results provide policy makers with insights into how strict food safety regulations of the home country can be considered as a catalyst for increasing competitiveness in international markets. Second, we examined the political determinants of SPS notifications using a nonlinear threshold model with possible threshold variables (GDP per capita and tariff rate). This article finds no threshold values in both variables of GDP per capita and tariff rate. Our results also show that GDP per capita has a positive relationship with SPS notifications that are one of proxy variables for food quality. That implies the importance of quality competition in agriculture and food sectors. Our finding also represents no significant effect of tariff on SPS notifications. This indicates that a law of constant protection, presenting an inverse relationship between tariff and non-tariff barriers, is not satisfied in the agricultural and food sectors. Third, we investigated the impact of tariff and SPS barriers on food manufacturers' skilled and unskilled employment in developing countries utilizing a structural equation model. Results show that both tariff and SPS barriers have a positive effect on unskilled labor employment in developing countries, while trade barriers are not associated with skilled labor employment. This implies that Hecksher-Ohlin theory, presenting labor abundant countries have a comparative advantage in labor-intensive industries such as food, explains well our results since developing countries are abundant in low-skilled labor. We also find that the age of food firm in developing countries is positively related to skilled employment; however, no relationship with unskilled employment. This implies that older food firms change their production process from labor intensive to capital or machine intensive. Many studies show that product quality plays an important role in determining the direction of trade. This project used the Safe Quality Food (SQF) certification as a proxy variable for quality to investigate its effect on U.S. exports. The results of this study show that only the highest level of SQF quality certification has a positive effect on U.S. agri-food exports. The results of this paper have three implications. Firms in the U.S. may want to become certified at the highest level of private standards if they are serious about increasing their exports. On the government side, they should consider employing high public standards or follow other strategies to promote development of high private standards. On the consumer side, SQF may have a signaling effect. SQF represents high quality in terms of food safety, which means that many consumers who want to buy high quality goods may enjoy the high quality products without risks of uncertain information.

The research efforts were also submitted and accepted by scientific journals such as Journal of Agribusiness, Journal of Food Distribution Research, and Journal of International Agricultural Trade & Development,which are forthcoming. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?The results demonstrated that stricter standard has a negative impact on EU trade, and a decrease in domestic welfare and international welfare. The analysis with domestic welfare justifies the EU's policy on tightening the food safety standard on importing shrimps if it wishes to protect domestic suppliers. However, EU consumers suffer from a welfare loss with stricter standards. The zero tolerance policy seems to violate the purpose of food safety standard that stricter standard should benefit consumers by providing food with higher quality, as it reduces consumer welfare. The zero tolerance policy is too tough. The results also showed that with stricter standards, the welfare of suppliers from developing countries is severely reduced while suppliers from developed countries benefit. This analysis of foreign and international welfare supports the assertion that developed countries have advantages over developing countries in the eyes of consumers. With food safety standards increasing with time, developing countries should increase their level of food safety by adopting advanced regulations or techniques so they don't suffer losses as regulations become more stringent. It was interesting to find that developing countries might benefit from the MRPL. Their products were suspect before the enforcement of MRPL in 2002 because of the detection of high hazard to human health. After the EU relieved the required level of MRPL, consumers bought more shrimp products from developing countries. Policy makers need to realize that their response to food safety scares has large impacts on producers and consumers throughout the world. They should be careful as they develop policies and regulations. For the obesity study, according to the analysis several factors combined with access to healthy food, are likely to be effective. The number of recreational areas and fitness facilities is important in decreasing the obesity rate. This would allow people with low incomes to access to these facilities. Even though many U.S. counties have a number of free recreation areas, most of the modern and high quality fitness facilities are private and require a certain amount of money to access them. Economically, a higher number of those structures will increase competition, which will cause a decrease in access fees. There is evidence that access to healthy food has a negative impact on obesity rates in the U.S. using county level data. The first recommendations for those who intend to use this analysis for different prospective is that U.S. counties need to increase the number of programs which operate on a daily basis during the year. The second is that counties should find possible ways to facilitate broader access to fitness facilities, whether by lowering users' taxes or by acquiring basic materials at low cost to improve their existing recreation area. Also important is encouragement for young people who are more at risk for obesity to eat healthier and to engage in physical activities. We also recommend to the population to do the best they can to increase their income in order to have more quality choices in their eating behaviors. Good health is priceless. It is better to prevent obesity in the first place by practicing healthy behaviors than to try to treat the consequences. How have the results been disseminated to communities of interest?The research efforts were accepted for publication by several scientific journals. The research efforts were also presented at the Southern Agricultural Economics Association Annual Meetings held on January 31-February 03 in Atlanta Georgia, and International Food and Agribusiness Management Association 25th Annual Meetings held on June 14-15 in Saint Paul, Minnesota.

The research articles and PowerPoint presentations are accessible by food industry leaders and managers, and academicians (professors, students, and professional) nationally and internationally through Ag-Econ Search website. What do you plan to do during the next reporting period to accomplish the goals?We are working on "Risk Perception and Trust Interaction in Response to Food Safety Events across Products and Their Implications for Agribusiness Firms." The objective of this study is to determine how consumers respond to hypothetical food safety events across different products and regions. The data for this research was obtained from two surveys of fresh produce and meat products. The SPARTA model, based on the Theory of Planned Behavior, is used to determine the impact of factors influencing consumers' purchasing decisions. We are also still working on our research that explores the links between the gravity model and welfare frameworks and apply the quantitative model system to analyze how trade and welfare is affected by the Minimum Required Performance Limits in the shrimp importing market of European Union. We're hoping to complete the final report and submit it to the American Journal of Agricultural Economics for publication. We are also working on "Price Linkages in the Brazilian Sugarcane-Ethanol Industry in the Post 2008 Financial and Economic Crisis," and "Price Adjustment and Market Power in the Columbian Milds Coffee Market."

Impacts
What was accomplished under these goals? One of our research focuses on the EU shrimp market and measures the impact of a stricter standard to control the residues of chloramphenicol on the EU shrimp market. The EU has explicitly specified the level requirement of Minimum Required Performance Limit (MRPL) on chloramphenicol and products, with levels beyond the MRPL being rejected. This article quantifies how the MRPL level influences EU shrimp imports from developing and developed countries and the associated welfare changes of EU consumers, EU suppliers, and foreign suppliers. It is hypothesized that the lower MRPL has negative effects on EU imports and that the reduction is greater for developing countries. Welfare impacts by type of supplier are calculated based on heterogeneity among shrimp suppliers and provides a new way to quantify welfare changes among countries with differing abilities to adjust to standard changes. Finally, this paper estimates EU welfare changes caused by the lower MRPL for shrimp. The approach used differs from previous seafood studies that focus only on the ex-post evaluation of trade effects, or on the evaluation of welfare effects via econometric analysis. This research explores the links between a gravity model and a welfare framework to analyze how trade and welfare is affected by the Minimum Required Performance Limit regulation in the EU shrimp import market. The "phi-ness" gravity model is used to investigate the trade effects of MRPL on shrimp imports The Poisson Pseudo Maximum Likelihood (PPML) method is incorporated into the estimation to control for zero-valued observations. Based on the theoretical foundation of the gravity model, the nested Constant Elasticity of Substitution (CES) model of consumers' utility is set up to further explore the linkages between these two models. The nested CES model incorporates the effects of MRPL on consumers' confidence in the domestic shrimp market as well as foreign shrimp imported from developed and developing countries. The empirical results confirm stricter MRPL had significant negative effects on trade integration between the EU and trading partners. The welfare analysis shows the zero tolerance policy of MRPL standard dramatically enhanced consumers' demand for domestic shrimp and foreign shrimp imported from developed countries, but reduced the quantity of shrimp supplied by developing countries. The results also show the increased level of MRPL led to an increase in the welfare of domestic consumers, suppliers in developing countries, and in total international shrimp trade, but decreased welfare of domestic suppliers as well as foreign suppliers from developed countries. The intent of another article was to measure the economic impact of access to healthy food on obesity. This study used a linear regression econometrics model to achieve this purpose. Obesity is considered as the dependent variable and a number of other factors such as the number and availability of farmers markets and Community Supported Agriculture programs in the U.S., the number and accessibility of fast food restaurants, and the availability of recreation and fitness facilities are considered as independent variables. Using the USDA county level data, the results showed that beyond access to healthy food, many other factors explain the observed variations in obesity rates in the model. Moreover, the results indicated that the increase of household income and the increase of full service restaurants both have a negative impact on obesity rate. It was also observed that age plays a significant role in explaining obesity with people over 65 who likely eat healthier than people under the age of 18. This study also discusses the factors contributing to the change in obesity rates in order to promote a quality healthy life.

Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? Foot-and-mouth disease (FMD) is a highly contagious viral-type disease which infects cloven-hoofed ruminant animals, such as cattle and pigs. The disease has had very destructive impacts on animal herds throughout the world. FMD symptoms include fever, erosions, and blister-like lesions on the hooves, lips, mouth, teats, and tongue (APHIS, 2007). FMD outbreaks can also affect consumption behavior because the disease can influence consumer perceptions about food health and safety. Food safety and animal life issues are increasingly impacting international agricultural trade. Member countries of the World Trade Organization (WTO) can apply measures of the Sanitary and Phytosanitary (SPS) Agreement to prevent the spread of pests or disease among animals and plants, and ensure safe food for consumers. Thus, it is common to have livestock and meat exports from a country banned because of FMD. Such a ban can have devastating impacts on a country’s livestock industry. Numerous studies have found that FMD outbreaks can dramatically influence consumption behavior, market prices, production in all stages, and meat product trade. Some of the studies focus on the effects on livestock supply contemporaneously and over time. Some studies have focused on the effects of FMD on meat demand. Previous studies that have estimated economic impacts of FMD have focused on specific domestic markets; the analysis of FMD outbreaks on global trade in pork products or the aggregate world trade is less discussed. In order to enhance the implication of global trade, this study attempted to investigate the effects of FMD on pork trade among numerous countries. Each country’s situation is different with regard to the structure of pork production, the importance of the pork processing sector in the economy, and the infrastructure that can be used to combat the disease. These issues are important in the decisions about combating the disease, but beyond the scope of this study. FMD-infected importers may not increase their pork imports, depending on which policy importers adopt. When time-related unobserved impacts were controlled, pork importers with a slaughter policy tend to increase pork imports. This relates to the shortage of domestic supply from controlling FMD outbreaks by destroying pigs. On the other hand, importing countries with a vaccination policy do significantly decrease pork imports when time-related unobserved impacts are controlled. In this case any shortage in domestic supply under a vaccination policy is more than offset by a reduction in domestic pork demand. How have the results been disseminated to communities of interest? The research effort was published in the Journal of International Agricultural Trade & Development, (9):1-20. It was also discussed at the departmental and college level as well as in my graduate course, Advanced Agribusiness Management, AEC 622 for MS and PhD students. The journals are accessed by food industry leaders and managers, and acadeimcians (professors, students, and professional) nationally and internationally. What do you plan to do during the next reporting period to accomplish the goals? Currently many countries apply Hazard Analysis Critical Control Point (HACCP) to control seafood safety. The diverse status of HACCP implementation by countries imposes import barriers and harms international trade in seafood. Many empirical studies concentrate on HACCP effects on seafood trade of developing countries. Only a few studies focus on U.S. seafood export markets. Our goal is to investigate and analyze the trade effects of different HACCP implementation systems by importing countries on U.S. seafood exports. We have investigated the status of HACCP implementation on a panel of the top 38 importing countries for U.S. seafood export market, and analyzed the trade effects based on their level of economic development and their extent of HACCP implementation. A gravity model with fixed-effects is adopted for the analysis. The findings suggest that the status of HACCP implementation in importing countries has differential impacts on seafood trade flows. U.S. HACCP has a positive impact on seafood exports to the majority of importing countries, except those where the status of HACCP implementation is unclear. The HACCP effects are more strong on groups of countries that directly adopted HACCP. The U.S.’s role in helping developing countries integrate HACCP into their existing food safety standards is also positive and significant. I will fully report on this effort during the next reporting period. We have also looked at the coffee as a differentiated product and major import and exporting markets. We investigate price transmission and market power in the Colombian Milds coffee beens. I will report on that as well. In another research, we explore the links between a gravity model and welfare frameworks and then apply the quantitative model system to analyze how trade and welfare is affected by the Minimum Required Performance Limits (MRPL) in the shrimp importing market of European Union. We're hoping to conduct and finish that research and report on that if time allows.

Impacts
What was accomplished under these goals? International pork trade has been affected by two conflicting effects in recent years: lower trade barriers because of free trade agreements and trade disruptions caused by disease outbreaks. This study investigated how global pork trade was affected by foot-and-mouth disease among major exporting/importing countries. The 41 countries included in this analysis account for 99% of world pork exports and 92% of world pork imports. A Pseudo Poisson Maximum Likelihood (PPML) estimator with a series of controlled fixed effects in the gravity equation was utilized. Results were statistically confirmed that pork exports fall when an exporting country reports foot-and-mouth disease. Exporters with a vaccination policy suffer larger negative impacts than those with a slaughter policy. Pork importers that report FMD and institute a slaughter policy will import more pork, but importers with a vaccination policy will import less pork.

Target Audience: This research has been published in the Journal of International Agricultural Trade & Development in 2013. The audience for this journal is all the univerity faculties, and studenets as well as policy makers, stake holders, and agribusiness managers. Also, the content was discussed university-wide, in the department with graduate students, and in my class, AEC 622, Advanced Agricbusiness Management, In the spring 2013. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? There has been already a concerted movement, led by Codex Alimentarius Commission (Codex), encouraging countries to focus their food safety regulations on improving public health through the use of risk analysis principles (Caswell and Bach 2007). Codex recommends the Hazard Analysis Critical Control Point (HACCP) system as a preferred set of standards to control food safety hazards (Unnevehr and Jensen 1999). A HACCP system monitors and controls critical points in the production process to prevent food safety hazards. How have the results been disseminated to communities of interest? This research has been published in the Journal of International Agricultural Trade & Development in 2013. Also, the content wasdiscussed in the department with graduate students, and in my class, AEC 622, Advanced Agricbusiness Management, In spring 2013. What do you plan to do during the next reporting period to accomplish the goals? We are continuing with research in the area of product differentiation, looking into high quality Colombian Arabica, and Vietnamese Robusta coffee markets as well human health issues related to Foot and Mouth desease.

Impacts
What was accomplished under these goals? This research seeks to explore the effects of food safety standards, specifically U.S. HACCP regulations, on U.S. exports of some seafood products, namely fish, mollusks, and shellfish.The hazards of seafood lie in the different food borne diseases inherent in various categories of seafood products. High concentration of pathogens, biotoxins and chemicals, as well as disease agents, may be present in seafood and therefore constitute serious hazards. Mollusks are a special concern because they are traditionally eaten raw or very lightly cooked; this further increases the risk (Huss, Ababouch and Gram 2004; Rippey 1994). For shellfish, Norwalk and gastrointestinal viruses are the most common causes of shellfish-associated diseases (Huss, Ababouch and Gram 2004). Unlike mollusks, the levels of pathogenic bacteria and viruses presented in raw fish are quite low and it is very unlikely that this low level of pathogens could cause any disease as the product is cooked before consumption. Non-indigenous bacteria and bacterial contamination during processing are responsible for most disease incidents in fish consumption (Ferri 2005). Our research investigates the effects of HACCP implementation on U.S. exports offish, mollusks, and shellfish other than mollusks.The results indicate that food safety regulations have differential effects across seafood products. The HACCP effect on seafood exports of mollusks, which have higher inherent hazards, is positive and statistically significant. This coefficient infers that mandatory HACCP implementation has improved exports of mollusk products. The effects on the other two categories are positive,though not statistically significant.

OUTPUTS: The Sanitary and Phytosanitary (SPS) Agreement concerning foot-and-mouth disease (FMD) continues to be a major barrier regarding trade among countries. International pork trade has been affected by FMD outbreaks which lead disease-free exporters to gain market share. Global production and consumption of pork during 1996 to 2007 rose substantially. The demand for pork clearly offers opportunities for disease-free pork producers to expand international sales. The ranking of the top 20 pork exporters and importers have shuffled noticeably because of import bans from FMD-free importers, so that FMD-affected exporters have lost their global markets as a direct cause of FMD. Hence, global pork export patterns have been influenced by FMD events.This study investigated foreign FMD impacts on four major pork exporters, Canada, Germany, Spain, and the U.S. The results confirm that foreign FMD have impacted pork exporters differently. Germany has gained the most exports during foreign FMD outbreaks in pork importing countries; the U.S. is second, Spain is third, and Canada is fourth. European pork exporters have locational and lower transportation cost advantages over North American pork exporters.This research was presented at the 2012 International Food and Agribusiness Management in June in Shanghai, China. This research is also under review by the Canadian Journal of Agricultural Economics. PARTICIPANTS: Not relevant to this project. TARGET AUDIENCES: Not relevant to this project.

Impacts
Past research findings have shown: first, pork exports decline when an exporting country develops FMD, and exporters with a vaccination policy have larger negative impacts than those with a slaughter policy; second, overall pork imports increase when an importing country institutes a slaughter policy, but importers with a vaccination policy import the same level of pork. However, the competition among pork exporters is different for each exporting country. The FMD events during 1996 to 2007 greatly impacted global pork trade. Among the top 10 pork exporters, only Canada, U.S., Germany, and Spain showed strong growth in exports during that time. These four countries are FMD-free and have not had an outbreak, so they have not had bans imposed through the SPS agreements on FMD. Markets for FMD-affected pork imports have been captured by Germany no matter which policy is adopted by importing countries; the FTA that many countries have with Germany through the European Union is also helpful. The U.S. only seems able to capture increased exports when the importing country adopts a vaccination policy. FMD outbreaks don't seem to affect Spain pork exports, but they negatively impact Canadian pork exports when the importers adopt a slaughter policy. Hence, the empirical results reveal that Germany gains the most among these four countries when there is an FMD outbreak; the U.S. is next; followed by Spain and Canada. When the market competition between North American and European exporters is analyzed, importing countries with either slaughter or vaccination policies increase their pork imports from European countries when they have an FMD outbreak. However, North American pork exporters still hold markets where FMD-affected pork importers adopt a vaccination policy. Moreover, the pork import markets with a slaughter policy are primarily provided by European exporters rather than North American exporters. Hence, the analysis of pork exports between North America and European exporters shows that European countries have a better competition position than North American exporters when importing countries have FMD outbreaks. The different competitive environment between North American and European pork exporters during FMD events may link to several factors. First, vaccination policies were abandoned by the European Union after 1991 due to the successful eradication of FMD. Thus, most countries with a slaughter policy are European and other European pork exporting countries which are FMD-free are the largest beneficiaries. This situation benefits European pork exporters because they have locational advantages and lower transportation costs than North American exporters. Second, though North American and European exporters increase sales when importers adopt a vaccination policy, European exporters still receive larger positive impacts than North American exporters. Consequently, the analysis reveals that European exporters are relatively advantaged when there is an FMD outbreak.
