Short-Run Supply Responses in the U.S. Beef-Cattle Industry

This article investigates the response of beef-cattle producers to changes in the price of cattle. Previous research has suggested that there may be a negative short-run supply response to a permanent increase in the price of cattle. We build a dynamic, rational expectations model that separates the markets for fed and unfed beef. This separation generates predictions that the supply response is generally positive, even for permanent shocks in the short run, and nests the negative supply response as a special case for appropriately restricted demand shocks.     

China as a Potential Market for U.S. Pork Exports

This study provides details of emerging opportunities for U.S. pork exporters following the U.S.–China WTO Accession Agreement. The Agreement will enable the United States to gain unprecedented access to the Chinese pork market. The United States enjoys comparative advantages in producing hogs at lower cost, higher quality, and greater efficiency. Moreover, Chinese preference for pork is highly complementary to that of U.S. consumers. Therefore, U.S. pork exporters are expected to target primarily the Chinese variety meats market. Although China is expected to remain a surplus pork production nation, demographic shifts could provide additional opportunities for U.S. pork exporters to increase sales of more premium cuts for urban consumers in China.

Market and Cost Structure in the U.S. Beef Packing Industry: A Plant-Level Analysis

A resurgence of consolidation in the U.S. meat packing industry in the past few decades has stimulated academic and policy debate. Issues raised include the role of cost economies in driving these patterns, and the effects on the agricultural sector (cattle producers) from market power. Here, plant level cost and revenue data for U.S. beef packing plants are used to estimate a cost-based model incorporating cattle- and output-market pricing behavior. The robust results indicate little market power exploitation in either the cattle input or beef output markets, and that any apparent evidence is counteracted by cost efficiencies such as utilization and scope economies.     

Trade Liberalization,Policy Reform and the U.S. Sugar Industry

This study examines the prospects for and potential impacts of liberalized international trade in sugar. It utilizes a state specific, cost of production based estimate of U.S. sugar supply to examine producer surplus under the current sugar policy regime and under a free trade scenario. It also evaluates the long-term viability of sugar production in individual states at free market prices.

Estimating the U.S. Import Demand for Melons: A Dynamic Analysis Approach

The United States is one of the world's leading consumers as well as one of the world's leading producers of melons. However, U.S. melons are produced only from May through December. In order to supplement the domestic demand and make melons available year-round, the United States imports melons from Latin American countries. This article analyzes the U.S. demand for imported fresh and frozen melons using monthly data on import volumes and values. A static and a dynamic linear Almost Ideal Demand System are estimated using Seemingly Unrelated Regression (SUR). The estimated parameters are used to estimate the short- and long-run price and expenditure elasticities.     

Tracing the evolution of the aggregate U.S. milk supply elasticity using a herd dynamics model

The U.S. dairy sector is characterized by increasing volatility of milk prices, and consolidation in production as evidenced by declining number of dairy farms with an increasingly larger share of milk supplied from a small number of very large farms. Using aggregate national data, we build a mixed‐frequency herd dynamics econometric model of the U.S. milk supply that updates and substantially amends the model first proposed by Chavas and Klemme. We implement a dynamic residual‐based bootstrap technique that can be used in testing for changes in nonmarginal simulated long‐run supply responsiveness, and trace the evolution of long‐run milk supply elasticity from 1975 through 2010. Several papers in the past have suggested that long‐run supply elasticity increases with dairy farm size, which implies that increased importance of large farms would increase aggregate long‐run supply responsiveness. Contrary to this conclusion, we find a declining trend in long‐run supply elasticity from 1975 through 2005. Persistence of such a decline would be a major cause for worry, as ever larger price swings would be needed to equilibrate the market in face of demand shocks. However, we find that milk supply is becoming more responsive since 2005 both to milk and feed price changes. Increasing responsiveness to feed prices further justifies focusing the next generation of the dairy policy instruments on managing dairy profit margins rather than just revenue streams.     

European Consumers' Willingness to Pay for U.S. Beef in Experimental Auction Markets

Consumers' willingness to pay for Irish, Norwegian, U.S. hormone-free, and U.S. hormone-treated beef was studied in an experimental auction market. We ran four simultaneous second-price auctions to elicit efficiently the complete distribution of willingness to pay differences among our four alternatives. Most participants preferred domestic to imported beef, and half the participants preferred Irish to U.S. hormone-free beef. Hormone-treated beef received the lowest mean bid, but 28% of the participants were indifferent or preferred U.S. hormone-treated to U.S. hormone-free beef.     

A new market for an old food: the U.S. demand for olive oil

While U.S. consumption of olive oil has tripled over the past two decades, nearly all olive oil continues to be imported. Estimation of a demand system using monthly import data reveals that the income elasticity for virgin oils sourced from EU is above one, but demand for nonvirgin oils is income‐inelastic. The demand for olive oil as a single product is price‐inelastic. Differentiated by product characteristic and origin, olive oils are highly substitutable with each other but not with other vegetable oils. News about the health and culinary benefits of olive oil and the spread of Mediterranean diet contribute significantly to the rising demand.     

Trade Bans, Imperfect Competition, and Welfare: BSE and the U.S. Beef Industry

Between May 2003 and July 2005, the U.S. beef industry faced a total ban on Canadian cattle imports following the discovery of BSE in Canada in May 2003 and restrictions on U.S. beef exports following the discovery of BSE in the United States in December 2003. When the United States reopened its border to Canadian cattle in July 2005, shipments were restricted to cattle less than 30 months of age. The total ban on Canadian cattle imports and restrictions on U.S. beef exports overlapped between January 2004 and July 2005. The restrictions on Canadian cattle imports and U.S. beef exports overlapped for some time after July 2005. This paper addresses theoretically and empirically how to disentangle the impact on the U.S. beef industry of the BSE-related beef trade interruptions in the presence of overlaps and imperfect competition. Entre mai 2003 et juillet 2005, l'industrie bovine américaine s'est vue imposer une interdiction d'importer des bovins canadiens à la suite de la découverte d'un cas d'ESB au Canada en mai 2003 ainsi que des restrictions quant aux exportations de bœuf américain à la suite de la découverte d'un cas d'ESB aux États-Unis en décembre 2003. En juillet 2005, les États-Unis ont rouvert leur frontière aux bovins canadiens vivants de moins de 30 mois uniquement. L'interdiction absolue d'importer des bovins canadiens et les restrictions sur les exportations de bœuf américain se sont chevauchées entre janvier 2004 et juillet 2005. Les restrictions sur les importations de bovins canadiens et les exportations de bœuf américain se sont chevauchées pendant quelque temps après juillet 2005. Le présent article s'est penché sur les façons, théoriques et empiriques, de démĉler les répercussions que les interruptions du commerce du bœuf attribuables à l'ESB ont eues sur l'industrie bovine américaine en présence de chevauchements et de concurrence imparfaite.     

Issues Affecting the U.S. Poultry Industry and International Poultry Trade

Abstract

This study was conducted to examine issues and concerns that may affect the future direction of the U.S. poultry industry and international poultry trade. Given the economic contribution of the poultry industry, it is important to have some understanding about the future direction of the industry, both at the national and international levels. To generate the information required, this study surveyed the top poultry producers in the country as well as specialists and experts in the industry. Although both the producers and specialists believe that the industry has a bright future, they also think that the rapid production growth experienced by the poultry industry in the past two decades cannot be sustained. Growth restrictions in the industry will come from a variety of sources such as environmental waste management, food safety, labor shortages, animal welfare, and increased foreign competition.

Standards as Barriers Versus Standards as Catalysts: Assessing the Impact of HACCP Implementation on U.S. Seafood Imports

The United States mandated a Hazard Analysis Critical Control Points (HACCP) food safety standard for seafood in 1997. Panel model results for 1990 to 2004 suggest that HACCP introduction had a negative and significant impact on overall imports from the top thirty-three suppliers. While the effect for developed countries was positive, the negative effect for developing countries supports the view of "standards as barriers" versus "standards as catalysts." A different perspective emerges from individual country-level analysis. Regardless of development status, leading seafood exporters generally experienced a positive HACCP effect, while most other smaller trading partners faced a negative effect.     

Price Cycles and Asymmetric Price Transmission in the U.S. Pork Market

Economists have proposed several plausible explanations for observed price transmission asymmetries in commodity markets. Unfortunately, the econometric methods commonly used in such studies cannot empirically distinguish pricing behavior under the competing theories. We argue that the theories may be classified by firm responses to high- and low-frequency price cycles and use Engle's band spectrum regression to test the symmetry of high- and low-frequency cycles in weekly pork prices. The findings indicate that changes in wholesale prices are asymmetrically transmitted to retail prices in relatively low-frequency cycles, which does not support search costs and other high-frequency explanations. Conversely, wholesale pork prices asymmetrically adjust to changes in farm prices at all frequencies.     

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.     

Water rights: a comparison of the impacts of urban and irrigation reforms in Australia

Although there has been a policy thrust towards making all Australians more cognisant of the relative scarcity of water resources, the approach adopted for urban dwellers differs markedly from that applied to irrigators. These differences are examined from a property-rights perspective focussing primarily on the institutional hierarchies in the Victorian water sector. The analysis reveals significant attenuation of urban dwellers' rights, presumably on the basis of the information deficiencies that circumscribe urban water use. Alternative policy options are then proposed, which might alleviate some of these information deficiencies and simultaneously address the efficiency losses that attend the present arrangements.     

Regional productivity convergence: An analysis of the pulp and paper industries in U.S., Canada,Finland, and Sweden

In this paper we investigate the presence of productivity convergence in eight regional pulp and paper industries of U.S. and Canada over the period of 1971–2005. Expectation of productivity convergence in the pulp and paper industries of Canadian provinces and of the states of its southern neighbour is high since they are trading partners with fairly high level of exchanges in both pulp and paper products. Moreover, they share a common production technology that changed very little over the last century. We supplement the North-American regional data with national data for two Nordic countries, Finland and Sweden, which provides a scope to compare the productivity performances of four leading players in global pulp and paper industry. We find evidence in favour of the catch-up hypothesis among the regional pulp and paper industries of U.S. and Canada in our sample. The growth performance is at the advantage of Canadian provinces relative to their U.S. counterparts. The two Nordic countries, that had the lowest productivity levels in 1971, erased most of the gap and in some cases moved ahead of their North-American counterparts.     

Reputations, Market Structure, and the Choice of Quality Assurance Systems in the Food Industry

Many food traits desired by consumers are costly to provide and difficult to verify. A complicating factor is that delivered quality can only be affected stochastically by producers and imperfectly observed by consumers. Markets for these goods will emerge only if supplying firms can be trusted. We develop a repeated purchases model to explore how quality discoverability, market structure, nature of reputations, market premiums, and discount factors drive firm choice about the stringency of quality assurance systems designed to gain consumer trust. Reputation protection is key incentive for firms to invest in high-quality goods and quality assurance systems.
