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.     

U.S. Citrus Import Demand: Seasonality and Substitution

Citrus fruits make up 1/5 of all fresh fruit consumed in the United States. Given the increasing importance of imported citrus in the diet of American consumers, it is perhaps surprising that no import demand analysis of U.S. citrus has been conducted. Using quarterly U.S. import data for 6 citrus commodities, we employed a demand systems model and evaluated aspects of seasonality. The results suggest wide variations in price responses to different types of imported citrus. The average amplitude and phase shift suggest that all citrus fruits exhibit some seasonality in their imports, likely a result of peak harvesting schedules of exporters.     

The Nested PIGLOG Model: An Application to U.S. Food Demand

A new demand system is introduced, the Nested PIGLOG model, nesting thirteen other demand systems including five that are also new. This new model and its nested special cases are applied to models of U.S. food demand that include food-at-home (FAH), food-away-from-home (FAFH), and alcoholic beverages. Although nested tests and out-of-sample forecasting performance favor generalizing models to a certain degree, statistically insignificant improvements to in-sample-fit and even poorer out-of-sample forecast accuracy undermine further generalizations. Based on a subset of preferred models, FAFH is found to be price and income elastic compared to FAH which is price and income inelastic.     

Getting Something from Nothing: An Investigation of Beef Demand Expansion and Substitution

A relative increase in demand for one type of beef can have one of two potentially countervailing effects: it can cause substitution of one type for another and/or it might expand overall demand. The results of a random parameters logit analysis indicate that regardless of whether USDA Choice or upgraded steak demand increases, the expansion effect dominates the substitution effect. We also show that, for our sample of consumers, the introduction of a new "natural" steak causes a greater reduction in market share for USDA Choice beef than ungraded beef. Despite this result, however, overall steak demand increases.     

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.     

Consumer Demand for New Reduced-fat Foods: An Analysis of Cheese Expenditures

The dairy products industry is adjusting the types of products being marketed by increasing the availability of reduced-fat foods. The desire of consumers to purchase foods with lower fat content is affecting the cheese market with the introduction of recently developed reduced-fat cheese varieties. Econometric models of cheese expenditures for three specific cheese types are estimated, which incorporate censoring of cheese expenditures and the interrelationship between expenditures of full and reduced-fat varieties.     

Determining Opportunities for U.S. Exports of Consumer-Oriented Foods to African Regional Markets

Abstract

This study examines the level of trade between the U.S. and Africa for consumer-oriented agricultural products during the 1990s. To achieve this objective, we propose six congruent regional African markets and examine patterns of U.S. trade with Africa on consumer-oriented agricultural products. The reason for such groupings is to identify trade flow differences and similarities between the U. S. and each of these regional groups. The results shed light on the extent to which U.S. exporters of consumer food products are capitalizing on the emerging markets of Africa. The graphing technique used in the study, in combination with trend stability measures for the six proposed congruent regional African markets, introduce a method for identifying market opportunity.     

Dynamics and Long-run Structure in U.S. Meat Demand

Empirical analysis, based on a general dynamic Almost Ideal Demand System, shows the commonly used autoregressive and partial adjustment processes are restrictive to meat demand data. This study derives a linear specification in levels form to investigate dynamics in a general framework. Merging a long-run steady state structure with short-run dynamics results in consistent and robust long-run demand elasticities Une analyse empirique, basée sur un systéme dynamique général de demande quasi optimale, montre que les mécanismes courants d'ajustement autorégressif et d'ajustement partiel ont un effect restrictif sur l'évaluation des données de la demande de viande. Les auteurs proposent une spécifcation linéaire par niveaux pour examiner la dynamique du cadre général. La combinaison d'une structure stable de longue durée avec une dynamique de courte période a produit des élasticités cohérentes et solides de la demande à long terme     

A Microeconometric Analysis of the U.S. Meat Demand

Price and expenditure elasticities and estimates of the effect of household demographic variables on U.S. meat demand are estimated using the newly released 1987–88 USDA household food consumption survey data. The USDA survey for the first time included variables reflecting respondents' concerns for health and diet information. A hybrid demand system, which combines a modified generalized addilog system and a level version Rotterdam demand system, is developed as the analytical framework. The micro econometric analysis takes into consideration the consumer selection problem, the missing-price problem, and the aggregation and quality variation problem. The most significant household characteristic and socio-economic variables are region, ethnic background, household size, urbanization, food planner, received health information, female household head employment status and proportion of food expenditure on away-from-home consumption. The results support the speculation of other time-series meat demand studies claiming both health concerns and convenience are the reasons for changes in consumer preference in favor of poultry and fish and in disfavor of red meat.     

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.     

The Cotton Influence Index: An Examination of U.S. Cotton Subsidies

Given the lack of a bill or amendment specific to cotton, we introduce a Cotton Influence Index to capture legislators' influence in championing the cause of the cotton growers during the hearings of the Farm Security and Rural Investment Act of 2002. Regression analyses reveal a relationship between Cotton Influence Index and campaign contributions, cotton farmland, party affiliation, and ideology. Tobit analysis indicates a significant relationship between different "actions and participations" by representatives to advance the interest of cotton—that is, components of this index and their future cotton political action committees' (PACs) contributions to them.     

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.     

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.     

Demand for Domestic and Imported Table Wine in British Columbia: A Source-differentiated Almost Ideal Demand System Approach

The premium quality wine market in British Columbia has grown substantively over the past decade. However, few empirical studies exist to quantify how consumers have responded to these wines. This paper employs a source-differentiated almost ideal demand system (AIDS) model with time-varying parameters to estimate the demand for premium quality wines using scanner sales data from the British Columbia wine market. The empirical findings reveal that consumers' response to foreign-produced wines differs from that for wine produced locally. It is evident that the expenditure elasticities for British Columbia, European and Rest-of-the-World white wines are larger than those for red wines. The high expenditure elasticities associated with British Columbia white wines may suggest that these wines are associated with higher quality. We reject the hypotheses of block separability and product aggregation. There is no evidence of structural change from the tests employed in this paper.     

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.
