The Impact of Catfish Imports on the U.S. Wholesale and Farm Sectors AgEcon
Muhammad, Andrew; Neal, Sammy J.; Hanson, Terrill R.; Jones, Keithly G..
The primary objective of this study was to assess the impact of catfish imports and tariffs on the U.S. catfish industry, with particular focus on the U.S. International Trade Commission ruling on Vietnam in 2003. Given the importance of Vietnam to the U.S. catfish market, it was assumed that catfish import prices would increase by 35 percent if the maximum tariff was imposed on catfish from Vietnam. With the tariff, domestic catfish prices at the wholesale level would increase by $0.06 per lb, and farm prices by $0.03 per lb. Processor sales would increase by 1.66 percent. Total welfare at the wholesale level would increase from $69.2 million to $71.7 million, an increase of about 3.63 percent, and processor and farm revenue would increase by 4.4 percent...

Consumer demands for organic and genetically modified foods AgEcon
Donaghy, Peter; Rolfe, John; Bennett, Jeffrey W..
Issues concerning consumer demands for genetically modified and organic food remain topical. It is unclear how consumers perceive issues associated with food production such as food safety, environmental impacts or animal welfare. It is also unclear how consumers might value potential changes in those issues in regional and metropolitan centres. This paper reports on research using the choice modelling technique to estimate and compare consumer demand for genetically modified and organic foods in Australia. The case study considers tomatoes, milk and beef commodities. The results draw comparisons between the contribution of associated factors influencing consumer purchasing decisions in a regional and metropolitan city. The results are relevant to the...

Derivation of supply curves for catchment water effluents meeting specific salinity concentration targets in 2050: linking farm and catchment level models or “Footprints on future salt / water planes” AgEcon
Nordblom, Thomas L.; Bathgate, Andrew D.; Young, Robert A..
The salt burden in a stream reflects the blend of salty and fresh flows from different soil areas in its catchment. Depending not only on long-run rainfall, water yields from a soil are also determined by land cover: lowest if the area is forested and greatest if cleared. Water yields under agro-forestry, lucerne pasture, perennial grass pasture, and annual pasture or cropping options span the range of water yields between the extremes of forested and cleared lands. This study explores quantitative approaches for connecting the hydrologic and economic consequences of farm-level decisions on land cover (productive land uses) to the costs of attaining different catchment level targets of water volumes and salt reaching downstream users; environmental,...

U.S. Cotton Prices and the World Cotton Market; Forecasting and Structural Change AgEcon
Isengildina-Massa, Olga; MacDonald, Stephen.
This report analyzes recent structural changes in the world cotton industry and develops a statistical model that reflects current drivers of U.S. cotton prices. Legislative changes in 2008 authorized USDA to resume publishing cotton price forecasts for the first time in nearly 80 years. Systematic problems have become apparent in the forecasting models used by USDA and elsewhere, highlighting the need for an updated review of price relationships. A structural break in the U.S. cotton industry occurred in 1999, and world cotton supply has become an important determinant of U.S. cotton prices, along with China’s trade and production policy. The model developed here forecasts changes in the U.S. upland cotton farm price based on changes in U.S. cotton...

DEMAND FOR FOOD QUANTITY AND QUALITY IN CHINA AgEcon
Gale, H. Frederick, Jr.; Huang, Kuo S..
As their incomes rise, Chinese consumers are changing their diets and demanding greater quality, convenience, and safety in food. Food expenditures grow faster than quantities purchased as income rises, suggesting that consumers with higher incomes purchase more expensive foods. The top-earning Chinese households appear to have reached a point where the income elasticity of demand for quantity of most foods is near zero. China’s food market is becoming segmented. The demand for quality by high-income households has fueled recent growth in modern food retail and sales of premium-priced food and beverage products. Food expenditures and incomes have grown much more slowly for rural and low-income urban households.

Expected Changes in China's Grain and Oilseed Industries and Implications for the U.S. and World Agriculture AgEcon
Taylor, Richard D.; Koo, Won W..
A spatial optimization model was developed to analyze the impacts of structural changes in China’s consumption of wheat, corn, rice, and soybeans on its agricultural sector and world agricultural trade. The model included 16 exporting and importing countries and regions. China was divided into 31 provinces and the United States into 24 producing regions and 10 consuming regions. The model optimizes agricultural production and distribution systems to meet the predicted demand for grains and oilseeds in 2020 under several assumptions associated with technical progress in producing the grains and oilseeds in China, the United States, and other countries.

Exchange Rates and The Export Demand for U.S. Grapefruit Juice AgEcon
Guci, Ledia.
As the U.S. domestic demand for fresh grapefruit and grapefruit juice trends downward, the export markets become more and more important for the citrus industry. Prior research suggests that when studying export demand relationships, exchange rates play an important role. The purpose of this research project was to study the relationship between exchange rates and foreign demand for U.S. grapefruit juice. Monthly observations for the period from 1989 to 2007 were used in the analysis. The seemingly unrelated regression was used to estimate the demand equations for grapefruit juice by major importing country/region. The results of this study support prior research findings.

MODELLING THE DYNAMICS OF PRODUCTION ADJUSTMENT TO SHORT-TERM MARKET SHOCKS AgEcon
Niemi, Jarkko K.; Lehtonen, Heikki.
Models of agricultural economics typically operate at an annual basis or in a static equilibrium framework where inputs, outputs and their prices may change considerably. Production dynamics, however, imply that models relying on spatial and temporal aggregation do not capture the effects of biological constraints in the short run. This paper examines short and long-term impacts of demand and production cost shocks in the pig sector. The analysis is carried out with a dynamic programming model which takes into account changes in export and domestic demand and market clearing price. It optimizes the supply of piglets on a monthly basis. Econometric techniques are used to estimate demand functions. Short-term negative market shocks can already have...

Multivariate AIM Consumer Demand Model Applied to Dried Fruit, Raisins, and Dried Plums AgEcon
Brant, Molly; Marsh, Thomas L.; Featherstone, Allen M.; Crespi, John M..
Abstract: We estimate a semi-nonparametric demand system based on a multivariate version of the Muntz-Szatz series expansion which is called the Asymptotically Ideal Model (AIM). The model is applied to consumer demand for dried fruits, raisins, and dried plums. Results from the first and second order AIM expansions suggest that the second order expansion leads to a more economically consistent model, but the likelihood ratio test indicates the AIM(2) model was not a statistical improvement over the AIM(1) model.

Evaluating the Impact of Changing Mississippi’s Tobacco Tax AgEcon
Myles, Albert E.; Allen, Albert J..
A multiple regression was performed on 37 years of data to determine the impact of raising the tobacco tax on cigarettes by $.24 per pack on cigarette sales in Mississippi. The t-statistic for the slope was significant at the .05 critical alpha level, t(29) =1.69 and p=.05. Thus, we conclude that there is a positive significant relationship between taxes and sales volume. Further, about 91 of the variability in sales volume could be explained by the demand model.

An Analysis of Wal-Mart Refrigerated Orange Juice Sales AgEcon
Brown, Mark G..
In this paper, estimates of the impacts of various factors on the refrigerated OJ sales in Wal-Mart (WM) stores are presented. Data on WM stores, as well as grocery stores doing $2 million or greater annual business, across 52 Nielsen city markets (including the remaining U.S.) were studied. Since WM does not have stores in San Diego, this market was omitted. Weekly data for each city from week ending 3/11/06 through 3/01/08 (104 weeks) were included in the analysis. The relationship between WM refrigerated OJ dollar sales per store and 1) WM and $2million store prices, $2 million store promotions, a dummy variable to test whether sales may spike during periods when some consumers receive their paychecks (middle or end of the month), the number of same...

Taxing Sweets: Sweetener Input Tax or Final Consumption Tax? AgEcon
Miao, Zhen; Beghin, John C.; Jensen, Helen H..
In order to reduce obesity and associated costs, policymakers are considering various policies, including taxes, to change consumers’ high-calorie consumption habits. We investigate two tax policies aimed at reducing added sweetener consumption. Both a consumption tax on sweet goods and a sweetener input tax can reach the same policy target of reducing added sweetener consumption. Both tax instruments are regressive, but the associated surplus losses are limited. The tax on sweetener inputs targets sweeteners directly and causes about five times less surplus loss than the final consumption tax. Previous analyses have overlooked this important point.

UMA ANÁLISE DA ELASTICIDADE-RENDA DE PROTEÍNA ANIMAL NO BRASIL AgEcon
Carvalho, Thiago Bernardino de; Zen, Sergio de; Raimundo, Livia Maria Borges; Beduschi, Gustavo; Rodrigues, Regina Mazzini.
O Brasil possui um mercado interno potencial para o consumo de alimentos, principalmente para as proteínas animais. A carne, o leite e ovo já fazem parte da alimentação dos brasileiros e sua demanda está ligada a vários fatores, como preços, qualidade, aspectos nutricionais, preferência, gosto e, principalmente, a restrição orçamentária, ou seja, a renda. Junta-se a isso a proteína pescado, que mesmo sendo um alimento muito saudável, não tem um hábito de consumo consolidado no país. A fim de determinar o quanto a renda impacta o consumo de proteína animal, buscou-se neste trabalho estimar as elasticidades-renda da demanda de proteína, no Brasil e suas regiões. As elasticidades foram obtidas por meio do ajustamento de uma poligonal com três segmentos. Os...

Analyses of Generic Dairy Advertising, 1984-97 AgEcon
Blisard, Noel; Blayney, Donald P.; Chandran, Ram; Allshouse, Jane E..
Generic advertising raised fluid milk sales about 6.0 percent, or 18.1 billion pounds, between September 1984 and September 1997. Sales of cheese rose by about 6.8 billion pounds (milk equivalent) in the same period because of increased generic advertising. An assessment of 15 cents per hundredweight of milk sold commercially, mandated by the Dairy and Tobacco Adjustment Act of 1983, funded the advertising. Activities of the National Fluid Milk Processor Promotion Board also contributed to increased milk sales over the past year. Gross returns to dairy farmers between September 1984 and September 1997 were estimated to increase by $3.44 for each dollar spent on generic advertising.

Demand Potential for Goat Meat in Southern States: Empirical Evidence from a Multi-State Goat Meat Consumer Survey AgEcon
Nelson, Mack C.; Liu, Xuanli.
A survey conducted in 11 Southeastern states elicits consumers' demand and preferences for various goat meat products. The data permit examination of goat meat demand of ethnic populations and the diversity among the states surveyed. The study uses five econometric models to examine the current demand, potential demand, and demand related to season and occasions on the goat meat market. Our analysis suggests that there exist a substantial demand for goat meat and the potential increase in the demand. The findings also identify the major factors in the determination of goat meat purchasing behavior.

Relationship between the Unemployment Rate and the Demand for Orange Juice AgEcon
Brown, Mark G..
This study examined the relationship between the unemployment rate and the demand for OJ. Based on the demand estimates obtained, the hypothesis that unemployment is having a significant negative impact on OJ demand cannot be refuted. Over the sample period, the unemployment rate increased by about 4.5 points, resulting in a 7.7% to 12.6% decline in OJ demand, based on the alternative model estimates. The unemployment rate, however, has trended upward in recent years, raising the possible that it may be reflecting to some extent the impact of other trend related factors such as preferences for reduced calories.
