Effects of Bovine Spongiform Encephalopathy Outbreaks on U.S. Cattle and Beef Prices

U.S. trade of beef and live cattle declined substantially after the discoveries of bovine spongiform encephalopathy (BSE) in Canada and the United States in 2003. In this study, an econometric model is developed to estimate the effects of lifting trade restrictions on U.S. cattle and beef prices. Results show that increases in imports of Canadian cattle and beef would lower prices of slaughter steers, feeder steers, and retail beef, but these negative impacts would be more than negated by the positive effects on prices that would result if beef exports return to near pre-BSE levels.     

The Relationship between U.S. and Canadian Wheat Prices

This paper examines the relationship between the price for Canadian wheat and the price for U.S. wheat. While a great deal of the variation in the Canadian series can be attributed to oscillations in either the exchange rate or the U.S. price of wheat, changing technologies, shifting market power, the marketing strategies of major market participants, and domestic market conditions are also seen to play a role in the price determination process and should be considered when making longer-term forecasts. The fact that the most encompassing price linkage specifications identified in this study differ significanty from the specification in a number of forecasting models in use today should be a point of particular concern. Since many of the decision equations (area seeded, inputs purchased, etc.) in place in these models essentially are driven off the Canada U.S. price linkage equation, the observed misspecification may have a detrimental impact on all forecasted series. Les auteurs examinent les rapports existants entre les prix canadiens et les prix américains du blé. Si une grande portion de la variabilité observée dans la série de donnée canadienne peut s'expliquer par les taux de change ou par le prix américain du blé, l'évolution des techniques, les déplacements des marchés, les stratégies de commercialisation des grands intervenants commerciaux et les conditions du marché intérieur jouent apparemment aussi un rôle dans la formation des prix. Ces facteurs devraient done être pris en compte dans les prévisions à long terme. Le fait que les spécifications de liaisons de prix les plus complètes dégagées dans cette étude s'técartent significativement de celles en usage dans plusieurs modèles de prévision mérite qu'on s'y arrête. Comme un bon nombre d'équations de décision (superficies emblavées, agrofournitures, etc.) utilisées dans ces modèles s'éloignent de l'équation de liaison de prix canado-américaine, cet écart pourrait avoir un impact défavorable sur toutes les séries de prévisions.     

Impacts of Declining U.S. Retail Beef Demand on Farm-Level Beef Prices and Production

A systems model was estimated to determine the effects of declining U.S. retail beef demand on farm-level beef prices and production. Retail beef demand declined by nearly 66% from 1976 to 1999. Results indicate autonomous shifts in retail demand significantly impacted farm-level demands and production. Based on equilibrium multipliers, the 1976–99 reduction in beef demand decreased real slaughter cattle prices and production by 32.1% and 11.2%, respectively. Real feeder cattle prices and production decreased by 8.0% and 22.6%, respectively. Combining the decreases in farm prices and production, slaughter and feeder cattle producers experienced a real revenue reduction of $13.3 billion (61%) due to the long-term decline in demand.     

U.S. Farm Policy and the Volatility of Commodity Prices and Farm Revenues

A dynamic three-commodity rational-expectations storage model is used to compare the impact of the Federal Agricultural Improvement and Reform (FAIR) Act of 1996 with a free-market policy, and with pre-FAIR policies. Results suggest that FAIR did not lead to significant increases in long-run price volatility or revenue volatility. The main impact of pre-FAIR, relative to the free-market regime, was to substitute government storage for private storage in a way that did little to support prices or to stabilize farm incomes. Results also indicate that U.S. grain market volatility in 1995–2000 was due to fundamental market forces and not to FAIR.     

Relationships between U.S. and Canadian Wheat Prices: Cointegration and Error Correction Approach

This paper examines relationships between U.S. and Canadian wheat prices using the cointegration and error correction approach. The use of the error correction model is appropriate because U.S. and Canadian wheat prices are first-differenced stationary and cointegrated. The results suggest that both U.S. durum and hard spring wheat prices respond to restore equilibrium relationships with the corresponding Canadian price, while the Canadian prices do not. That is, the structure of the respective policies is such that the Canadian markets are largely insulated from influences flowing directly from the U.S., while U.S. markets are not insulated from Canadian influences. These results could be interpreted to support the contention that Canadian production subsidies and the implicit export subsidies would tend to undermine the U.S. price support program. The results also support the price leadership role for Canada in the durum and hard spring wheat markets. The implication is that with respect to durum and spring wheats, U.S. policies to artificially support domestic prices are not effective over the long run. Les rapports entre les prix de blé canadiens et américains sont étudiés á partir des analyses basées sur la cointégration et la méthode de correction des erreurs. L'emploi de la méthode de correction des erreurs est approprié car les prix de blé canadiens et américains sont cointegres et stationnaires quand Us sont exprimes en changements (first differences). Les résultats montrent que les prix du blé dur (durum) et du blé panifiable du printemps (hard spring) aux États- Unis reagissent à l'évolution des prix canadiens pour retablir le rapport d'équilibre tandis que ceux du Canada ne sont pas influencés par les désequilibres. Ce résultat est explique par les differences entre les structures des politiques agri-coles quifont que les marches canadiens sont largement isoles des influences en provenance des États-Unis, ce qui n'estpas le cas pour les marches américains. Ces résultats pourraient vouloir dire que des subventions canadiennes à la production et à l'exportation ont mine les programmes américains de sou-tien des prix. Us sont également compatible avec l'idée que le Canada établit les prix sur ces marchés.     

Quarterly Dynamic Relationships Between the U.S. Wheat Market and Wheat-Related Prices for Products Downstream

Abstract

A quarterly VA R econometric model of the reduced form relationships between the U.S. wheat market and prices of processed wheat-related flour, bread, and other bakery products downstream was estimated. The model then simulated under a rise in production- or import-induced increase in wheat quantity, and a decline in wheat price, to examine the dynamic effects on the U.S. wheat market and on processed wheat-related prices downstream. U.S. trade negotiators at the upcoming WTO agricultural round, Federal policy makers, farmers, and agribusiness agents should be interested in the dynamic patterns with which negotiated trade conditions, farm policy alterations, and climatic variation influence wheat quantity and price, and in turn the price of more highly processed wheat-based products downstream.     

Changing the U.S. Sugar Program into a Standard Crop Program: Consequences under the North American Free Trade Agreement and Doha

We analyze the impact of continuing the existing U.S. sugar program, replacing it with a standard program, and implementing the standard program with multilateral trade liberalization. Under the North American Free Trade Agreement (NAFTA), duty-free sugar imports from Mexico could undermine the program's ability to operate on a no-cost basis to taxpayers as large public stocks of sugar could accumulate. The replacement of the current sugar program by one similar to other major U.S. crop programs would solve the problem of potential stock accumulation, accommodate further trade liberalization under a new WTO and future bilateral trade agreements, but would induce significant fiscal outlays through direct payments.     

Impacts of the U.S.-Canadian Potash Dispute on the Costs of U.S. Crop Production

The 1987 U.S. antidumping case against Canadian potash producers has had a significant impact on the production costs of major potash-using crops in the United States. This paper examines these impacts for selected U. S. crops by way of a counterfactual analysis. A transfer function is used to model retail potash prices and the change in the series resulting from the case. Results indicate that expenditures on potash by U. S. farmers increased by an average US $ 0.08 per acre for wheat to US $ 1.78 for potatoes during 1988–92 (July-June). Overall, total U.S. potash expenditures increased by an estimated US $ 629.1 million over this period as a result of the antidumping case.

The Effects of NAFTA on Trade and Welfare in the U.S. Fresh Tomato Industry

Abstract

The purpose of this study was to measure NAFTA's impact to date and quantify how the producers and consumers of fresh tomatoes in the United States, Canada and Mexico have benefited or lost. Changes in consumer and producer surpluses were calculated in 2001 US dollars based on simulations of two scenarios. The analysis found that U.S. consumers captured $12.1 billion more surplus than they would have captured had NAFTA not been enacted. Mexican fresh tomato producers gained an additional $2.08 billion in surplus due to NAFTA. In contrast to Mexican growers, U.S. and Canadian producers appear not to have benefited economically from NAFTA. Findings suggest that U.S. producers would have earned $3.29 billion more if NAFTA had not gone into effect. Canadian producer surplus with NAFTA was estimated to be approximately $20 million less with NAFTA, and the total net benefit from NAFTA was found to be a positive $10.87 billion.     

Generic Advertising of U.S. Lamb

ABSTRACT

Generic advertising of U.S. lamb by the U.S. sheep and lamb industry is an effort to reverse an almost continual decline in the industry since World War II. This analysis explores the answers to three related questions: (1) What have been the effects of the generic lamb advertising on U.S. and foreign sheep, lamb, and wool markets? (2) Has the generic lamb advertising program effectively increased the consumption of domestically produced lamb as intended rather than imported lamb? (3) What have been the returns to U.S. sheep producers, feeders, and packers who pay for the advertising? Using a 70-equation, non-spatial, price equilibrium, simultaneous econometric simulation model of the world sheep, lamb, and wool markets, the analysis concludes that the U.S. lamb industry’s generic lamb advertising program has positively impacted their markets, enhanced profitability of the industry, and increased the industry’s share of domestic lamb consumption.     

Efficiency of U.S. conservation-compliance program

Under the conservation-compliance program, most of the individual producers are forced to cut their soil erosion to 7 t per acre annually irrespective of the marginal cost of controlling soil erosion. In a system where coupons to a ton of soil loss were issued to producers and traded, the marginal cost of controlling soil loss within each soil type and across different soil types would be equalized. An instrumental variable procedure was used to determine the effect of soil erosion on net profits. The results for Iowa show that there is considerable difference in the marginal opportunity cost of controlling soil erosion between soil types. By assigning one ton of erosion to Iowa soil type Downs (5-10% slope) instead of Clarion (2-5% slope), there is a savings of $5.00 per acre for the society as a whole. The tradable coupon system is not only efficient, but will also bring in more land under soil conservation.     

U.S. Agricultural Trade with Mexico

Abstract

This study examined the effects of exchange rates, economic growth, trade liberalization, and export assistance programs on U.S. agricultural exports to Mexico. The Commodity Credit Corporation's GSM-102 Export Credit Guarantee Program reduces the risk associated with export financing and payment. The impact of the export credit guarantee program on U.S. agricultural exports to Mexico was estimated in an import demand model using quarterly data from 1980 to 1996. The results indicate that for every $1 of export credit guarantees, Mexican imports of U.S. farm products increased $0.30. Real income growth in Mexico, however, was the most important factor in the expansion of U.S. exports. Trade liberalization under NAFTA also increased U.S. exports to Mexico.     

U.S. Demand for Imported Wines

The U.S. is viewed as a lucrative market outlet for surplus wines produced in the leading wine exporting countries in the world. Structural U.S. import demand functions were estimated for French, Italian, Spanish, Portuguese, and German wines as well as for those that are U.S. produced. The equations were estimated with two-stage least-squares because of simultaneity between quantity demanded and price. Direct price, cross, and income elasticities were calculated to determine the degree of competiveness among the various wines of differing origin. Two separate groups of wine were identified. First, U.S. produced, French, and German wines were in one group. Spanish, Portuguese, and Italian wines comprised the second group. The latter group also encountered competition from the first group of wines.     

Estimating the Implicit Prices of Beef Cattle Attributes: A Case from Alberta

Pressures on beef producers to provide lean beef of consistent quality have been mounting in recent years. Yet this requires beef breeders to alter and broaden cattle improvement objectives to include carcass merit traits. They need information on heritability and the values associated with genetic traits in order to effectively do this. This study estimates the implicit prices in east‐central Alberta, Canada, for bull attributes using a hedonic pricing model. The results indicate that the most important bull attributes to buyers (breeders) in this region are sale weight, birth weight and scrotal circumference. Also important are ribeye area and average daily gain. Selection of these attributes conforms with expectations because they are moderately to highly heritable and are associated with improved fertility and reproduction, reduced production costs and higher returns. In addition, the results suggest that breeders have been changing selection emphasis away from reproduction traits and toward carcass traits associated with improved production efficiency and consumer demand. Depuis quelques années, les producteurs subissent des pressions grandissantes pour fournir du b?uf maigre de qualité uniforme. Ces pressions contraignent les éleveurs à modifier et àélargir leurs objectifs d'hybridation en y incluant les caractères génétiques qui codent les paramètres de la carcasse. Pour y arriver, les éleveurs ont besoin de renseignements sur l'héritabilité et la valeur des caractères en question. Dans cet article, le prix implicite des attributs des taureaux dans le centre‐est de l'Alberta est estimé selon un modèle hédoniste. Les attributs les plus importants pour les acheteurs (éleveurs) de la région sont le poids à la vente, le poids à la mise bas et la circonférence du scrotum. Comptent aussi pour beaucoup la surface du faux‐filet et le gain quotidien moyen. La sélection de tels attributs est conforme aux prévisions, car il s'agit de caractères très héréditaires qu'on relie à une fertilité accrue et de meilleures aptitudes à la reproduction, done à une réduction des coûts d'élevage et à un rendement plus élevé. Par ailleurs, les résultats de l'analyse laissent croire que les éleveurs ont réorienté leurs programmes de sélection, laissant de côté les aptitudes à la reproduction pour les paramètres de la carcasse associés à un meilleure productivité et à la demande des consommateurs.     

The U.S. Federal Crop Insurance Program

The US. Federal Crop Insurance Program has evolved from a government-run yield insurance program for wheat farmers to a public-private partnership that provides a variety of yield and revenue insurance products to producers of over 100 different crops. US. policy-makers continue to struggle with defining an appropriate role for the federal government in helping crop farmers manage revenue risk. New approaches using area-yield or weather-based options may hold promise for the future     

U.S. Canned Tuna Supply and Demand

Abstract

A 3SLS econometric model is used to estimate price elasticities of supply and demand for domestically produced and imported canned tuna in the U.S. market. In addition, a VAR model is developed to examine the relations between imports and domestically produced canned tuna. For domestically produced canned tuna, a 3SLS estimation of a structural econometric model yielded a coefficient for price elasticity of supply of 0.2 and of own-price demand of ?0.3. Such price inelasticities are expected of a fishery exploited at or near its maximum yields (inelastic supply), and a consumer product widely viewed as almost a necessity in a well-stocked pantry (inelastic demand). In addition, the model yielded a cross-price elasticity of demand with respect to the price of imported canned tuna of 0.45. Additional results include an income elasticity U.S. demand for domestically packed tuna of 0.83; a cross-price elasticity with the price of bread (a complement) of ?0.33, a cross-price elasticity for the price of ground meat (a substitute) of 0.30. With respect to imported canned tuna in the U.S. market, the corresponding elasticities estimated in the model are ?1.3 (own-price demand), 3.5 (income elasticity), ?1.2 (cross-price with the price of bread) and 2.5 (cross-price with the price of ground meat).

For canned tuna company managers, the results provide useful information about the likely effects on sales that would come from their own price changes, from changes in the price of imported canned tuna, and from price changes in the markets for complementary and substitute products. They can also use our results in discussions with U.S. trade negotiators, who are frequently faced with disputes over tariffs, market access, and other trade issues.     

Evaluating the U.S. Wheat Protein Complex

This paper models the economic linkages between a commodity (wheat gluten) and a commodity characteristic (wheat protein). The purpose of this research is to address several issues in the wheat protein complex including the impact of the U.S. gluten import quota on producer protein premiums. Four important conclusions are found. First, the hard red winter (HRW) protein market strongly influences wheat gluten market but the wheat gluten market has its greatest influence on the hard red spring (HRS) protein market. Second, the demand for intrinsic protein is estimated to be very elastic. Thus, the returns to breeding or biotechnology programs designed to raise protein levels of wheat are likely to remain stable in response to small increases in wheat protein content. Third, the U.S. import quota on wheat gluten is estimated to provide a 14% increase in the price of wheat gluten in the first year. By the third year, prices are only 5% above the prequota price. U.S. gluten supplies increase about 15% in the first year and remain at about that level for the next two years. Although these are small estimated impacts, they are not far from what the USITC had anticipated. Finally, the three‐year quota increases protein premiums and provides about $500 ($1000) in additional revenue for an average 1000‐acre farm producing HRW (HRS) wheat. Les auteurs ont modélisé les liens économiques entre un produit (le gluten de blé) et une de ses caractéristiques (les protéines). L'objectif était de répondre à plusieurs questions associées au complexe des protéines du blé, notamment l'incidence du contingentement des importations de gluten par les États‐Unis sur les primes consenties aux producteurs en fonction de la valeur protéique du blé. De leur étude, les auteurs tirent quatre grandes conclusions. La premiére est que le marché des protéines du blé roux vitreux d'hiver (BRVH) exerce une forte influence sur le marché du gluten qui, lui, influe principalement sur le marché des protéines du blé roux vitreux de printemps (BRVP). Deuxiémement, on estime que la demande de protéines intrinséques est trés élastique. De petites hausses de la teneur en protéines du blé devraient donc se traduire par un rendement stable des programmes d'hybridation ou de biotechnologie destinés à augmenter la concentration de protéines dans le blé. En troisième lieu, on estime que le contingentement des importations de gluten par les États‐Unis a entraîné une majoration de 14 % du prix de ce produit la premiére année. Deux ans plus tard, les cours s'étaient stabilisés à 5 % au‐dessus du prix en vigueur avant le contingentement. L'offre américaine de gluten augmentera d'environ 15 % la premiére année et se maintiendra à peu prés au même niveau les deux années suivantes. Même si elles ne sont guère importantes, pareilles retombées se rapprochent de celles anticipées par l'USITC. Enfln, les trois années de contingentement ont donné lieu à un relèvement des primes versées pour la concentration en protéines et débouché sur une hausse moyenne de 500 $ (1 000 $) du revenu des exploitations de 1 000 acres qui produisent du BRVH (BRVP).
