A NOTE ON BIAS IN THE ESTIMATED EFFECTS OF BEEF IMPORTS ON U.S. MEAT PRICES

The impact of beef imports on United States meat prices is a highly emotional and controversial issue. Congressmen representing urban districts, and to a lesser extent the Administration, look towards beef imports as a way of containing rapid increases in meat prices. Congressmen and Senators from beef-producing States regard beef imports as a direct attack on the U.S. beef-producing industry. These differing views are being reconciled through Congress considering amendments to the Meat Import Law (Public Law 88-482). The impacts and the amendments are of vital interest to Australia because about 25 per cent of Australia's beef production is sold on the lucrative U.S. market. In this note it is argued that, in general, the reported impacts on U.S. meat prices are overestimates because the analysts misspecify the structure of the U.S. beef industry.     

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.     

Imports versus Domestic Production: A Demand System Analysis of the U.S. Red Wine Market

The U.S. wine market experienced rapid growth in all facets—production, consumption, exports, and imports—over the past decade. Red wine imports more than tripled while consumption of domestically produced red wines doubled. This research estimates demand elasticities of U.S. red wine imports from five countries accounting for over 90% of imports—Italy, France, Spain, Australia, and Chile—using the first-difference version of the almost ideal demand system (AIDS). These elasticities are compared with those for domestically produced red wine. Results for conditional expenditure elasticities indicate that the U.S. red wine industry gains over imports when U.S. consumers' total expenditures on red wine increase. However, comparing own- and cross-price elasticities reveals an increase in the price of U.S. red wine results in a decline in quantity demanded six times greater than for French and Italian red wines and over 20 times greater than other import countries, thus harming the U.S. red wine industry. Empirical results suggest that U.S. red-wine producers could increase their total revenue by decreasing prices, while Italian and French producers can increase total revenues by increasing them.     

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.     

Effect of Sugar Price Policy on U.S. Imports of Processed Sugar-containing Foods

The relationship between U.S. and world sugar prices, and U.S. import demand for four categories of sugar-containing products is examined. Results from econometric estimation indicate that U.S. intervention in the sugar market has helped to increase U.S. imports of some sugar-containing products, but that increased disposable income has played a more important role. Although some developing countries have benefitted from U.S. sugar policy by increasing their exports of sugar-containing products to the United States, U.S. sugar policy has helped imports from developed countries proportionately more than those from developing countries as a whole.     

An Analysis of Removal of Agricultural Trade Barriers between the United States and Canada with Emphasis on the Southeast

A four-region, 23-commodity small world agricultural trade liberalization model within the SWOPSIM framework is used to measure the impact of tariff removal between the United States and Canada. The tariffs are simply defined as negative import subsidy equivalents in the model and are then removed from the trade prices. The model recalculates domestic supply and demand levels in all regions, rebalancing world trade, production, consumption and prices. In summary, the impacts of the Canada-U.S. Trade Agreement on selected commodity groups are significant. Canadian imports of beef and veal, poultry meat, soybean oil and fresh strawberries increase. Furthermore, the results indicate larger trade flows for selected products and declines in producer and consumer prices in Canada, U.S. and Southeast regions. Since the U.S. share of Canadian agricultural imports averaged 60% in the 1980s, the impact of trade liberalization will be greater in Canada in selected commodities than in the U. S. or the southeastern region, and Canadian dependence on the U.S. market will be increasing in the future. The tariff phaseout, together with a reduction in nontariff barriers and harmonizing of domestic agricultural policies, will create more export opportunities in selected commodities for both the United States and Canada, and will create the world's largest free trade market.     

Effects of North American BSE Events on U.S. Cattle Prices

In May 2003, a beef cow in the Province of Alberta tested positive for bovine spongiform encephalopathy (BSE or mad cow disease). In December of 2003, a dairy cow in the state of Washington also tested positive for BSE. These discoveries disrupted cattle and beef trade in North America and major export markets. We examine the effects of these two North American BSE events on U.S. fed and feeder cattle prices. The results indicate that the demand for U.S. beef was affected to a much greater degree by the reactions of foreign governments to the BSE announcements than by the reactions of U.S. households.     

A Spatial Equilibrium Analysis of U.S.–Canadian Disputes on the World Softwood Lumber Market

This paper utilizes a world spatial equilibrium model to examine the effects of U.S.–Canadian softwood lumber disputes on U.S., Canadian, and other exporters' and importers' lumber markets. Results show that the U.S. import tariff on Canadian softwood lumber impacts prices, supply, demand and trade flows not only in the United States and Canada but also in the other countries. Though the goal of U.S. trade restriction is to limit imports from Canada and protect its producers, the United States cannot fully accomplish this goal as non-Canadian exporters fill the void left by the reduced imports from Canada. Canadian producers lose from the U.S. policy, but their loss is mitigated as Canada redirects its exports to other importers. Importing countries such as Japan and the European Union benefit from the U.S. trade restrictions as Canada seeks to sell its softwood lumber to these countries.     

The linkage between the U.S. ethanol market and developing countries’ maize prices: a panel SVAR analysis

The major expansion of U.S. ethanol production raises concerns about the potential detrimental impacts on developing countries’ agricultural prices, farm income, and food security. To assess the sensitivity of maize prices to ethanol production, this study explores the linkage between the U.S. ethanol market and developing countries’ maize prices. The econometric approach, based on a panel structural vector autoregression model, captures market interdependencies and the likelihood that developing countries’ responses are both heterogeneous and dynamic. The results indicate that the U.S. ethanol market's impacts on maize prices in developing countries are heterogeneous and that coastal countries are more susceptible to U.S. economic shocks. The estimates also suggest that countries more dependent on food imports and/or receiving U.S. food aid are at a higher risk of being affected by such shocks. Overall, the results indicate that those countries with the greatest sensitivity and exposure to global agricultural commodity markets could benefit from domestic policies and international assistance, which reduce their exposure to impacts from the U.S. maize market.     

Econometric Examination of U.S. Potato-Related Market Relationships

Abstract

Modeling results, from a U.S. International Trade Commission investigation, that illuminate potato-related competitive conditions, particularly U.S. market impacts of potato imports, are presented. Estimation and simulation results of a monthJy vector autoregression model of the U.S. fresh and frozen trench fry markets suggest that the own-price elasticity of fresh table potato demand is more moderately elastic than previously thought; that U.S. fresh potato and trench fry markets only modestly interact, because the fresh table market residually and infrequently supplies raw product to processors; and that increased U.S. imports of fresh Canadian potatoes are likely a regional problem in Northeast U.S. markets, and do not appreciably influence potato-related prices or quantities nationally. Given the scarce potato-related literature, the model's estimated market parameters arc of interest.     

Demand System Estimation with Upward-Sloping Supply

There are three important implications of this work. First, demand systems estimates that overlook supply response are as subject to simultaneous equations bias as single ad hoc demand equations. Theil shows theoretically that assuming supply curves are perfectly elastic, when in fact they are not will underestimate price responsiveness in demand equations. An empirical example is presented that demonstrates that the price elasticities generally increase when upward-sloping supplies are assumed.
Second, the iterative testing procedure presented may provide direction for model building when the true structure of the system is unknown. For example, the results of the Wu-Hausman test indicate that assuming chicken supply is perfectly elastic in a model of the Japanese livestock industry is justified. The results also indicate that the supplies of Wagyu beef, dairy beef, pork and fish are upward-sloping and therefore should be modeled as endogenous variables in the demand system.
Third, the results emphasize the sensitivity of projections of Japanese beef imports to the assumptions underlying the demand system. If perfectly elastic meat supplies are assumed for an analysis of reducing Japanese beef import liberalization, the results will likely underestimate the impacts on beef imports.
In summary, the supply curves for agricultural products tend to slope upward within the time periods used for traditional policy analysis and demand system estimation, which in turn implies that prices are determined endogenously within the system. Endogenous price determination is contrary to the assumptions that underlie the theoretical foundations and many empirical applications of demand systems. We present a methodology to test for and adjust demand systems for endogeneity. The importance of this adjustment is demonstrated by using an analysis of the liberalization of the Japanese beef market.     

How integrated are world beef markets? The case of Australian and U.S. beef markets

The objective of the paper is to examine market integration between Australian and U.S. beef prices at the farmgate level. If these two prices are found to be integrated then it can be alleged that Australian beef prices can be used as a world price in empirical analyses and/or as a ‘reference price’ to measure the level of support accorded the U.S. beef sector. Co-integration analysis and a time-varying parameter estimation procedure based on the Kalman filter model are applied. The paper distinguishes between steer and cow beef segments and it uses monthly data over the 1972:1 to 1993:2 period. The results indicate that Australian and U.S. beef prices are co-integrated, albeit not fully and that the degree of convergence between the various price pairs has not substantially increased over time. The results also suggest that Australian prices can not unequivocally be adopted as a world price in empirical analyses.     

Forecasting Japan's Frozen Potato Imports

THe U.S. potato industry is the main supplier of frozen potatoes to a rapidly growing Japanese food service market. A two-stage budgeting procedure was employed to estimate total Japanese imports of frozen potatoes and imports by country of origin. Japanese demand for frozen potatoes was found to be own-price inelastic and income elastic. The complementary relationship between hamburger and frozen potatoes suggests that replacement of tariffs for beef import quotas will impact the Japanese potato market. Imports from the United States are expected to increase substantially and remain in constant proportion to total imports.     

Tariff quota administration in China's grain markets: An empirical assessment

In 2016, the U.S. launched a trade dispute against China at the World Trade Organization, arguing that China has been restricting its grain imports via tariff quota administration. Despite sharp criticisms by the U.S., the extent to which the grain imports were restricted in China remains largely unknown, primarily due to that China's grain import behaviors are still under-researched. The U.S. grain export sector might actually gain little from China's grain trade liberalization in the short run, since China has become less import dependent on the U.S. through the pursuit of import diversification. In this context, this article aims to quantify impacts of the tariff quota administration on China's grain imports from its trading partners. We calculate ad valorem tariff equivalents of the tariff quota administration and then estimate import demand elasticities using a source differentiated import demand model. We find that the tariff quota administration might have reduced China's quota fill rates for the grain commodities by 10–35% during 2013–2017. In particular, the U.S. wheat exports to China were largely negatively affected. We also find that the tariff quota administration in China acts like a variable import levy—its import restrictiveness varies negatively with world prices, leading to lower import demand elasticities.     

The U.S. demand for imported and domestically produced foods: An investigation of intertemporal and substitution effects

This article extends the literature on time series estimation of U.S. consumer demand by presenting a coherent theoretical structure with a multi-period planning horizon for consumer choice and a more general treatment of the aggregation problem that allows the possibility that consumers' tastes change over time and vary across individuals. Based on our theoretical model, an econometric model is used to obtain estimates in a multi-period context of U.S. demand for imported foods and domestically produced foods. The hypothesis that current purchases depend on expected future prices is supported by the empirical results for imported foods.     

Offsetting Price Impacts from Imports with Generic Advertising and Promotion Programs: The Hass Avocado Promotion and Research Order

California avocado producers, concerned about sharp increases in imports from Chile and Mexico, secured passage of national legislation to include financial participation by imports in U.S. generic promotion programs. Estimated demand parameters for avocados indicate that new advertising and promotion funded by the 2.5 cents per pound assessment on all Hass avocados sold in the U.S. can offset a portion of the price impact of increased imports. Producers of other specialty crops may want to investigate the feasibility of using national promotion and research orders to expand demand when faced with increased production or imports.     

The effects of the Yuan‐dollar exchange rate on agricultural commodity trade between the United States,China, and their competitors

The United States claims that the undervaluation of Chinese currency, the Yuan, causes U.S. exports to China to decrease and imports from China to increase. Furthermore, because the Yuan is undervalued only against the dollar, U.S. competitors have an advantage in exporting to China and China has an advantage over its competitors in exporting to the United States. This study develops a theoretical model to analyze the effect of the Yuan undervaluation on prices, supply, demand, and trade in the United States, China, and their competitors. This study applies a cointegration/error‐correction model to empirically quantify the short‐run and long‐run effects of the devaluation of the Yuan on important agricultural commodities traded between the United States, China, and their competitors. These commodities include Chinese imports of milk, soybeans, and cotton from the United States and U.S. imports of beans, fruit juice, and fruit from China. The results show that Yuan devaluation causes Chinese imports of U.S. milk, soybeans, and cotton to decline and U.S. imports of beans, fruit juice, and fruit from China to increase in the short run and in the long run.

Comparing heterogeneous consumption in U.S. and Japanese meat and fish demand

This article uses national, quarterly data to conduct an empirical analysis of pre‐committed meat and fish demand by U.S. and Japanese households using the generalized almost ideal demand system (GAIDS). Pre‐committed demand represents the component of demand that is insensitive to both income and price adjustments. U.S. consumers are found to hold significant positive pre‐committed demand for beef and pork, while Japanese consumers appear to possess significant, positive pre‐committed demand for beef and fish. This provides evidence to partially explain observed differences in Japanese and U.S. consumer reactions to nonprice and nonincome effects in beef, pork, poultry, and fish. In addition, based on in‐ and out‐of‐sample performance, the more general GAIDS is preferred to the almost ideal demand system (AIDS) for both the U.S. and Japanese demand systems. Results lend to improved demand modeling efforts and more complete understanding of true market forces at hand in meat and fish markets for these culturally diverse consumer groups.     

The Impacts on U.S. and Canadian Slaughter and Feeder Cattle Prices of a U.S. Import Tariff on Canadian Slaughter Cattle

On 30 June 1999, the U.S. Department of Commerce issued a preliminary ruling instructing the U.S. Customs Service to require cash deposits or bonds totaling 4.73% (later increased to 5.57%) of the value of imported Canadian slaughter cattle. In November 1999, the U.S. International Trade Commission issued its final ruling which rescinded the anti‐dumping tariff. If the tariff had been permanently imposed, it would have affected import quantities of Canadian slaughter cattle and U.S. and Canadian slaughter and feeder cattle prices. Excess supply, import demand and price transmission elasticities are estimated and used within a comparative statics framework to estimate the impacts of the tariff had it been permanently imposed. We find that the effects of the tariff would have been small even if offsetting increases in carcass beef imports had not occurred. If offsetting carcass beef imports had occurred, any potential price gains could have been offset by increased logistical costs within the processing sector. Thus, this particular rent‐seeking activity would not have had a significant impact on U.S. cattle prices even if it had been permanently imposed. However, the tariff would have had significant negative effects on Canadian cattle prices. Le 30 juin 1999, le Département du Commerce des États‐Unis obligeait temporairement les douanes américaines à réclamer un dépôt ou une caution équivalant à 4,73 pour cent (portée à 5,57 pour cent par la suite) de la valeur des bovins de boucherie importés du Canada. En novembre de la même année, la Commission du commerce international américaine rendait sa décision finale, qui abrogeait le tarif anti‐dumping. Eût‐il été maintenu, pareil tarif aurait modifié les importations de bovins d'abattage canadiens, ce qui aurait affecté le prix des bovins d'engrais et d'abattage des deux pays. Les auteurs ont éalué l'offre excédentaire, la demande à l'importation et les élasticités du transfert des prix, puis ont recouru à un cadre de comparaison statique afin d'estimer les incidences du tarif, advenant le cas où il aurait étéétabli à demeure. On se rend compte qu'un tel tarif n'aurait guére eu de répercussions, même en freinant la hausse des importations de carcasses de büf. La majoration éventuelle des prix attribuable à la réduction des importations aurait pu être annulée par les coûts logistiques plus élevés des transformateurs. Par conséquent, cette activité de maximisation de la rente n'aurait pas eu d'impact significatif sur le prix des bovins aux États‐Unis. En revanche, l'imposition permanente du tarif aurait sensiblement diminué le prix des bovins au Canada.
