Aplicación de un sistema de demanda casi ideal (AIDS) en cortes de carne (Bovino, Porcino y Pollo) y Huevo en México 1995-2008
Provedor de dados: 32
Autores: Ramírez Tinoco, Jesús.
En este trabajo se estiman las elasticidades de la demanda Marshallianas, Hicksianas y  del gasto para diferentes productos como: cortes de carne de bovino (bistec y cortes  especiales), porcino (bistec, pulpa y molida), pollo entero, huevo y tortilla. Para ello se  estimó un Sistema de Demanda Casi Ideal (AIDS), bajo Ecuaciones Aparentemente no  Relacionadas (SUR), aplicando el índice de precios Stone. De acuerdo con los  resultados de las elasticidades precio propias Marshallianas y Hicksianas, 11 de 12  productos resultaron con elasticidad menores a uno o sea inelásticos. En el caso de las  elasticidades precio cruzadas las combinaciones que resultan como sustitutos son:  bistec de bovino con cortes especiales de bovino, porcino (bistec, pulpa y molida)...

Preferencias del consumidor de frijol (Phaseolus vulgaris L.) en México
Provedor de dados: 32
Autores: Rodríguez Licea, Gabriela.
La producción constante, las importaciones, la disminución en el consumo y el ineficiente sistema de comercialización de frijol (Phaseolus vulgaris L.) han favorecido el aumento en los inventarios. Con el objetivo de proporcionar elementos que permitan orientar a los productores hacia las variedades de mayor consumo, se realizo un estudio sobre los gustos y preferencias de los consumidores para determinar cuales son las tendencias de consumo. Se aplicaron encuestas en las principales ciudades de las regiones Norte, Noroeste, Occidente, Centro y Sur del país. Los resultados indican que existe una marcada heterogeneidad en el consumo. A nivel nacional el de mayor preferencia es el grano a granel seguido del beneficiado e industrializado. Del grano los tipos...

Biophysical and social systems are linked to form social-ecological systems whose sustainability depends on their capacity to absorb uncertainty and cope with disturbances. In this study, we explored the key biophysical and socio-cultural factors underlying ecosystem service supply in two semiarid watersheds of southern Spain. These included variables associated with the role that freshwater flows and biodiversity play in securing the system&amp;#8217;s capacity to sustain essential ecosystem services and their relationship with social demand for services, local water governance, and land-use intensification. Our results reveal the importance of considering the invisible dimensions of water and biodiversity, i.e. green freshwater flows and trait-based...

Provedor de dados: 5
Autores: Roque D'Orbcastel, Emmanuelle; Sauzade, Didier; Ravoux, Georges; Coves, Denis.
Sea fish farms with production of more than 20 tons per year in France must obtain two operating licences: (i) one for Sea Farming (AECM), with the aim of ensuring that the granted site and use of the maritime public domain for exploitation will respect all restrictions of general interest; (ii) one for regulating Facilities Classified for the Protection of the Environment (ICPE). Although the first one requires a relatively simple licence request file, the second one demands a very complete file, which includes, beyond the notice of exploitation information, a complete impact study, as well as a hazards study and a health and safety notice. In this context, petitioners in Corsica (adjustment of status or new exploitation) are faced with the same...

Exploring demand for forestry in Lake Victoria Basin (Western Kenya): An econometric approach
Provedor de dados: 31
Autores: Jindal,   Rohit.
This paper determines the demand for a forestry program amongst rural households in western Kenya. It is based on a field survey with 277 households, using a stratified random sampling approach. The study follows attribute based method to elicit farmers’ preferences. Demand is measured in terms of additional number of trees that a household is willing to plant under different price schedules, including direct economic incentive to plant new seedlings. The mean willingness to plant new trees per household increases from 44 trees when farmers have to pay 10ksh/seedling, to 244 trees when farmers receive a payment of 10ksh/seedling. The paper uses fixed effects, random effects and random effect tobit models to estimate relevant parameters. Hausman...

Autores: Slattery,   Henry; Griffith,   Garry R.; Malcolm,   Bill; Dunshea,   Frank.
This is the third of a series of papers examining the potential economic effects from the introduction of a hypothetical low cholesterol pork product into the Australian market. Here, a newly updated pig meat model reported by Griffith et al. (2010) is used to model the industry wide impacts of the Bellhouse et al. (2010) survey results on consumer willingness to pay for this new pork product. Six different scenarios are examined that are combinations of a 10, 20 or 30 per cent increase in consumer demand, with and without a 10 per cent increase in the costs of producing the more valuable pork. The simulation results for the various scenarios indicate total annual industry benefits of some $450m for an increase in aggregate willingness to pay of 30 per...

Growing Demand for Animal-Protein-Source Products in Indonesia: Trade Implications
Provedor de dados: 31
Autores: Fabiosa,   Jacinto F.
New elasticities were estimated from Indonesia's 1996, 1999, and 2002 National Socio-Economic Survey, or SUSENAS, data using a double-hurdle demand specification. The estimates suggest that major changes in Indonesian household diets are expected in the coming years, as income growth is sustained and as urbanization proceeds at a fast pace. The consumption 'trading-up' pattern for animal-protein source products observed in many countries may also occur in Indonesia. In this particular case, households will shift from fish to dairy and meat products. The trade impacts of this emerging consumption pattern will be determined by the cost of adjustment in Indonesia's domestic productive capacity and the influence of the country's predominantly Islamic tradition.

A Study of the Demand for Medical Services in Taiwan
Provedor de dados: 31
Autores: Chung,   Rebecca H.; Lee,   Jonq-Ying; Brown,   Mark G.
This paper presents a version of the household production theory to explain the demand for health.  In this study we have explored the factors that influence the demand for medical services and medical expenditures in Taiwan.  A negative binomial model was used to study the demand for medical services.  We found that the demand for medical services and medical expenditures are related to household composition, household income, family size, occupation of the household head, and living environments.  In addition, we found higher usage of medical services on average for those households with medical insurances other than the national health insurance.

Competition between the U.S. and West Africa in International Cotton Trade: A Focus on Import Demand in China
Provedor de dados: 31
Autores: Muhammad,   Andrew; McPhail,   Lihong Lu; Kiawu,   James.
We estimate the demand for imported cotton in China and assess the competitiveness of cotton-exporting countries. Given the assertion that African cotton producers are ill affected by U.S. cotton subsidies, our focus is the price competition between the C4 countries (Benin, Burkina Faso, Chad and Mali) and United States in China. Demand estimates are used to project how U.S. prices affect China’s imports by country. In comparing demand projections, results show that the relationship between the United States and the C4 has more to do with how U.S. prices can affect global prices rather than any substitute or competitive relationship in the Chinese market.

This research proposes the estimation of a partial equilibrium econometric and simulation international trade model for sorghum: United States and Mexico component. Sixteen equations were simultaneously estimated and validated as a system using seemingly unrelated regression. Results on parameter estimates agree with economic theory and a working model for simulation and forecast was obtained. Forecast scenarios suggest that the dependency of sorghum trade between US and Mexico will continue.

Nile perch demand in the Netherlands: are exports from Kenya, Tanzania and Uganda source-differentiated?

Autores: Muhammad,   Andrew.
This study examined Nile perch demand in the Netherlands and assessed the importance of country of origin as a determining factor. Import demand equations were estimated using the absolute price version of the Rotterdam model where Nile perch fillets were differentiated by product form (chilled and frozen) and by source country (Kenya, Tanzania and Uganda). The Armington framework (source-differentiation) is often used when estimating import demand for a similar product from different sources; however, the results of this study indicated that country of origin is not a factor in the Netherlands when importing Nile perch. Results showed that the responsiveness of importers to price changes was the same regardless to the supplying country. Likelihood ratio...

Autores: Blaine,   Thomas W.; Reed,   Michael R.
A framework was developed in order to specify a model for annual U.S. per capita consumption of cigarettes.  Three separate time related variables were utilized to measure the effects of health related information regarding smoking.  The empirical results from the post World War II data set reveal that while prices and income are important determinants of cigarette consumption, the estimates for both were in the inelastic range.  The age distribution of the adult population is also an important variable.  While the development of the filter tip has been successful in stimulating smoking, the low tar and nicotine innovation has not had a statistically significant effect.  Health information has repeatedly produced substantial short and long run effects....

THE PRODUCTION THEORY APPROACH TO IMPORT DEMAND ANALYSIS: A COMPARISON OF THE ROTTERDAM MODEL AND THE DIFFERENTIAL PRODUCTION APPROACH
Provedor de dados: 31
Autores: Washington,   Andrew A.; Kilmer,   Richard L.
Results indicate that, when comparing the unconditional derived-demand elasticities to the unconditional consumer demand elasticities, significant differences emerge due to the differences in the first-stage estimation procedure between the differential production approach and the Rotterdam model.  In comparing the consumer demand price/corss-price elasticities to the derived-demand price/cross-price elasticities, it is clear that use of the Rotterdam model when a production approach should be used can lead to overestimation, underestimation, and incorrect signs in deriving unconditional price effects.

An Economic Analysis of Corn-based Ethanol Production
Provedor de dados: 31
Autores: Koo,   Won W.; Taylor,   Richard D.
A global multi-commodity simulation model was developed to estimate the impact of changes in ethanol production on the U.S. corn industry. Increased ethanol production under the Energy Acts of 2005 and 2007 resulted in a significant increase in the price of corn. However, for corn-based ethanol production, the break-even price of corn is approximately $4.52 per bushel with a federal subsidy of $0.51 per gallon of pure ethanol and $2.50 gasoline. With a corn price of $4.52, the economically desirable ethanol production is approximately 11 billion gallons. In order to produce 15 billion gallons of corn-based ethanol and to maintain the price of corn at $4.52 per bushel, supply of corn in the U.S. should be increased substantially through increases in corn...

Fresh-Cut Melon - The Money Is in the Juice
Provedor de dados: 31
Autores: Mayen,   Carlos D.; Marshall,   Maria I.; Lusk,   Jayson L.
Fruit is an important component of the food industry in the United States, and “fresh-cut” products are an increasing portion of that consumption. We found that packaging and juice content played a significant role in the choices Indiana consumers made when purchasing fresh-cut melon products. Brand was not as important as the other fresh-cut melon attributes. Indiana consumers had a clear dislike for cup-shaped transparent packages compared with tamper-proof, bowl, and squared packages.  However, they were willing to pay a premium for packages that have no fruit juices on the bottom.

Growing Demand for Animal-Protein-Source Products in Indonesia: Trade Implications
Provedor de dados: 31
Autores: Fabiosa,   Jacinto F.
New elasticities were estimated from Indonesia's 1996, 1999, and 2002 National Socio-Economic Survey, or SUSENAS, data using a double-hurdle demand specification. The estimates suggest that major changes in Indonesian household diets are expected in the coming years, as income growth is sustained and as urbanization proceeds at a fast pace. The consumption "trading-up" pattern for animal-protein source products observed in many countries may also occur in Indonesia. In this particular case, households will shift from fish to dairy and meat products. The trade impacts of this emerging consumption pattern will be determined by the cost of adjustment in Indonesia's domestic productive capacity and the influence of the country's predominantly Islamic tradition.

Autores: Hone,   Phillip; Haszler,   Henry; Tubuna,   Sakiusa; Waqavonovono,   Epeli.
An understanding of the responsiveness of food demand to price changes is critical to decision making in the area of food policy. The estimation of these elasticities is difficult in developing countries, such as Fiji, due to a lack of reliable data. We review the existing data on food demand elasticities in Fiji and examine alternative approaches to their estimation given the data constraints present. We use a stated preference approach to provide a new set of estimates of food demand elasticities for Fiji using cross section data.

Autores: Brown,   Mark G.
An extension of the Rotterdam model is developed that makes the model’s income flexibility and marginal propensities to consume varying coefficients. Frisch’s duality relationships that the second partial derivatives of demand with respect to income and prices are independent of the order of differentiation are imposed with the marginal propensities to consume specified as functions of income and price, and the Slutsky coefficients specified as functions of income only. A uniform substitute specification is used to analyze the conditional demands for a group of beverages.

Autores: Zheng,   Yuqing; Kaiser,   Harry M.
As a first effort at modeling nonalcoholic beverage demand in a systemwide framework that includes bottled water, this article examines the impact of advertising on the demand for nonalcoholic beverages in the United States. We employed an AIDS (almost ideal demand system) model of five jointly estimated equations that included advertising expenditures as explanatory variables to evaluate annual U.S. consumption of nonalcoholic beverages for 1974 through 2005. Results suggest that advertising increases demand for fluid milk, soft drinks, and coffee and tea, but not for juice or bottled water. Advertising spillover effects occur in over 50 percent of the cases considered, and such effects can be substantial, particularly for advertising of soft drinks, and...

The value of market uncertainty in a livestock epidemic
Provedor de dados: 31
Autores: Niemi,   Jarkko K.; Lehtonen,   Heikki.
Introduction of foot and mouth disease (FMD) into country typically initiates eradication procedures which remove animals from the market, and halts the export of livestock products from the infected country. The magnitude of these effects can be highly uncertain. This paper presents a stochastic dynamic programming model which simulates possible market implications of alternative FMD and export scenarios in the Finnish pig sector. It takes into account dynamics and adjustment of the animal stock, price movements and uncertainty related to the duration of the trade ban.  Results suggest that losses to pig producers can increase considerably when the risk of prolonged export ban increases. Production adjustments also strengthen. Consumers can gain from a...

What Influences Tastes? An Analysis of the Determinants of Consumers’ Demand for Tastes in Food
Provedor de dados: 31
Autores: Drichoutis,   Andreas C.; Lazaridis,   Panagiotis.
This article explores the factors affecting demand for tastes in food. Following Silberberg (1985) we divide demand for food into demand for nutrition and demand for  tastes. We first compute the minimum cost required to fulfil the Recommended Daily  Allowances (RDAs) of households and attribute the difference of minimum cost from actual expenditures as the expenditure for tastes. Since prices are essential in deriving the minimum cost and data do not allow for the derivation of prices for food consumed away-from-home (FAFH), we also present a way to account for the FAFH expenditure. Data from the 1998/99 Greek Household Expenditure Survey are used. Results indicate a number of socioeconomic factors such as income, household size, urbanization, age and...

Impact of U.S. duty drawback on the demand for orange juice
Provedor de dados: 31
Autores: Brown,   Mark G.; Fernandes,   Waldir B.; Spreen,   Thomas H.; Lee,   Jonq-Ying.
A demand system model differentiating goods by origin is developed to examine impacts of duty drawback on U.S. orange juice exports and prices.  An empirical analysis suggests that on average duty drawback has increased annual orange juice exports by about 16.5 million SSE gallons or 11% of export sales, and has supported the U.S. price of orange juice by about 2 cents per gallon.  Not all benefits of duty drawback go to exporters.  Importers who own drawback credits but do not export product may realize benefits by selling their credits to exporters.  The analysis suggests these benefits effectively reduce by the U.S. orange juice tariff, positively impacting imports and negatively impacting the U.S. price.

U.S. banana demand differentiated by country of origin is estimated using the generalized dynamic Rotterdam model.  Results indicate that dynamic factors play a significant role in determining the allocation of U.S. banana expenditures across exporting sources.  Of particular interest is Guatemala’s increased share and Costa Rica’s decreased share of U.S. banana supply.  A number of factors explained why Guatemala replaced Costa Rica as the leading U.S. supplier in 2007.  (1) Guatemala is the least expensive source on average.  (2) Habit persistence, adjustment costs, and other dynamic factors favor Guatemala’s exports.  (3) Given increases in the relative price of Costa Rica’s bananas, the price competition between Costa Rica and Guatemala is highly...

The future role of China in world wheat markets is a compelling and important issue for producers in the Northern Plains. Some analysts have estimated that China will continue to demand large quantities of imported wheat. Others have forecast that China will gradually move to a position where domestic supply will meet the nation's demand for wheat. China's own economists also have conflicting views. Chinese Academy of Agricultural Sciences researchers have predicted that the nation will remain at least self-sufficient and could be a large exporter. China's net imports of grain decreased steadily between 1989 and 1993. Moreover, despite large imports in 1994 and 1995, China has had an overall agricultural trade surplus with the United States during most of...

Autores: Fofana,   Abdulai; Clayton,   Patty.
Demand relationships between salmon and a number of wild-caught whitefish and shellfish species using both single equation models and linearised AIDS system framework. The system is well represented although autocorrelation were found in both approaches but this is less of a problem in the systems approach. A cautious interpretation of the results indicated that salmon had a long-run market relationship with the whitefish species of cod, monkfish, saithe, whiting and plaice and with the shellfish species of mussels, nephrops, scallops and shrimp. These groups contain the main seafood species consumed within the United Kingdom, and therefore should include most potential substitutes for salmon.

This study characterizes the household food-away-from-home (FAFH) expenditure pattern in Egypt. Specifically, a standard Tobit model was estimated to quantify the responsiveness of Egyptian household FAFH expenditures to changes in their income and selected household demographic characteristics.   We found that the proportion of households with a positive FAFH expenditure is small, at 36% to 38% of the total number of households. These households spent 5% to 8% of their total expenditure on FAFH. Households that are located in urban areas, with more family members, and whose household head is young and male had generally higher levels of FAFH expenditure. The estimated conditional income elasticity is only 0.02, and the unconditional income elasticity is...

THE IMPACT OF PROMOTION AND ADVERTISING: A LATENT CLASS APPROACH
Provedor de dados: 31
Autores: Richards,   Timothy J.
Typically, marketers define market segments by their demographic characteristics, assuming that these segments represent consumers with relatively homogeneous buying patterns.  A more managerially useful definition, however, groups consumers of similar behavior directly and then seeks to find demographic commonalities among them.  This study uses a latent class analysis technique to segment consumers based on their responsiveness to a set of marketing variables, finding that a multiple-segment model provides a better fit to the data, and that these segments differ significantly in their responsiveness. By targeting marketing activities to their most responsive segments, the efficiency of commodity promotion can be dramatically improved.

A flexible, full rank two model of food consumption that is globally consistent with economic theory, aggregates across income, demographic variables, and variations in micro demand parameters, and accommodates tradeoffs between tastes and nutrition is derived.  The econometric demand model is estimated with per capita U.S. consumption of 21 foods on the time period 1919-1994, excluding the World War II years 1942-1946.  An approach for inferring the percentage of nutrients available from individual commodities in the U.S. food supply is derived and implemented empirically on the time period 1949-1995 for the nutrients energy, protein, total fat, carbohydrates, and cholesterol.  The two sets of model results are combined to generate time paths for income...

As the greatest rainwater users among all vegetative land covers, tree plantations have been employed strategically to mitigate salinity and water-logging problems. However, large-scale commercial tree plantations in high rainfall areas reduce fresh water inflows to river systems supporting downstream communities, agricultural industries and wetland environmental assets. A bio-economic model was used to estimate economic demand for water by future upstream plantations in a sub-catchment (the 2.8 million ha Macquarie valley in NSW) of the Murray-Darling Basin, Australia. Given four tree-product values, impacts were simulated under two settings: without and with the requirement that permanent water entitlements be purchased from downstream entitlement...

ECONOMIES OF SCALE, HOUSEHOLD SIZE, AND THE DEMAND FOR FOOD: THE MISSING LINK
Provedor de dados: 31
Autores: Benin,   Samuel.
For the same level of per capita resources, larger households are deemed better off due to possible scale economies from consuming household public goods. Contradictory evidence that per capita demand for food declines with household size has puzzled economists. This paper suggests that larger households have costs associated with sharing food, especially high-value foods, and so they substitute towards cheaper and basic foods, whose per capita demand increases with household size. However, since high-value foods form a larger proportion of the budget on all foods, per capita demand for all foods declines with household size when Engel food-share equation is estimated using aggregate food expenditure data.

Generalized Rational Random Errors

Autores: LaFrance,   Jeffrey T.
Theil's theory of rational random errors is sufficient for strict exogeneity of group expenditure in separable demand models. Generalized rational random errors is necessary and sufficient for strict exogeneity of group expenditure. A simple, robust, asymptotically normal t-test of this hypothesis is derived based on the generalized method of moments. An application to per capita annual U.S. food demand in the 20th century strongly rejects exogeneity of food expenditure in a model that in all other respects is highly compatible with the data set and with the implications of economic theory.

AN ASSESSMENT OF DYNAMIC BEHAVIOR IN THE U.S. CATFISH MARKET: AN APPLICATION OF THE GENERALIZED DYNAMIC ROTTERDAM MODEL
Provedor de dados: 31
Autores: Muhammad,   Andrew; Jones,   Keithly G.
Dynamic demand systems have been employed in a number of studies to account for habit formation and inventory adjustments in demand. Few studies have attempted to provide a theoretical foundation for the dynamic demand structures employed. Recently, Bushehri (2003) showed how a generalized dynamic Rotterdam model could be derived from the neoclassical intertemporal utility maximization problem; however, no empirical application is provided in his study. This paper provides an empirical application of the generalized dynamic Rotterdam model to the demand for processed catfish products in the U.S. The two-period dynamic Rotterdam model explained a significant amount of the variation in U.S. catfish demand and was preferred to the one-period and static...

U.S. Cotton Prices and the World Cotton Market:  Forecasting and Structural Change
Provedor de dados: 31
Autores: Isengildina-Massa,   Olga; MacDonald,   Stephen.
The purpose of this study was to analyze structural changes that took place in the cotton industry in recent years and develop a statistical model that reflects the current drivers of U.S. cotton prices.  Legislative changes authorized the U.S. Department of Agriculture to resume publishing cotton price forecasts for the first time in 79 years.  In addition, systematic problems have become apparent in the forecasting models used by USDA and elsewhere, highlighting the need for an updated review of price relationships.  This study concluded that a structural break in the U.S. cotton industry occurred in 1999, and that world cotton supply has become an important determinant of U.S. cotton prices.  China’s trade and production policy also continues to be an...

Taxing Sweets: Sweetener Input Tax or Final Consumption Tax?
Provedor de dados: 31
Autores: 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 sweet 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 analyzes have overlooked this important point.

Demand for Nutrients: The Household Production Approach
Provedor de dados: 31
Autores: Chung,   Rebecca H.; Lee,   Jonq-Ying; Brown,   Mark G.
This study uses the household production theory to study the demand for nutrients, i.e., households purchase a combination of food items from the market and produce the needed nutrients from these food items. By following the traditional household production approach, shadow prices for nutrients in food consumption are calculated. The cost function that generates the shadow prices appears plausible in terms of its elasticities of substitution and factor demand. After obtaining the calculated shadow prices of nutrients, the nutrient demand functions are estimated. Results show that the own-price elasticity of demand for nutrient is inelastic, whereas the expenditure elasticities indicate that nutrients are normal goods. Crossprice elasticities show that...

Autores: Brown,   Mark G.; Lee,   Jonq-Ying.
This study extends Barten's synthetic demand modeling approach to increase the flexibility of the uniform substitute specification of the Rotterdam demand system. Marginal propensities to consume (MPC) vary with budget shares and Slutsky coefficients are defined in terms of varying MPCs. An application of the model to orange-juice products shows that the pattern of income and price elasticities over time is much different than when MPCs are restricted to be constant.

Television Advertising and Soda Demand
Provedor de dados: 31
Autores: Lopez,   Rigoberto A.; Liu,   Yizao; Zhu,   Chen.
This study examines the effects of television advertising on consumer demand for carbonated soft drinks using a random coefficients logit model (BLP) with household and advertising data from seven U.S. cities over a three year period. We find that advertising decreases the price elasticity of demand, indicating that advertising plays predominantly a persuasive, therefore anti-competitive role in this market. Further results show that brand spillover effects are significant and that measuring advertising with gross rating points (GRPs) outperforms measuring it with expenditures, as is conventionally done. Finally, simulation results indicate that eliminating all television advertising would lower market shares of sodas as consumers migrate to other...

Some Further Discussion on the Price Index for  The Almost Ideal Demand System: A Chain Price Index Approach
Provedor de dados: 31
Autores: Brown,   Mark G.; Lee,   Jonq-Ying.
The issue of identification of the parameter α0 in the price index of the Almost Ideal Demand System (AIDS) is examined.  In nearly all empirical studies, the model’s likelihood function has been extremely flat in α0, and this parameter has not been able to be estimated.  Assumed values are often used.  In this paper, an AIDS-like model is developed with an easy- to-calculate chain-price index that replaces the price index in the original AIDS.  The model stands by itself with respect to consumer demand theory and flexibility. An empirical analysis of beverage demands gives merit to the specification.

In order to fall under a prospect for sustainable management of the natural resources in Cameroon, this communication tries, using a 1996 survey carried out from 400 households in the towns of Yaounde, Mbalmayo and Ebolowa, to understand the demand behaviours of the urban households, with respect to the various sources of energy. The work aims to highlight the place of the firewood like source of energy. The results obtained confirm the important place of the firewood in its various forms like source of energy in urban areas and thus indicating a threat on the future of the natural resources, in particular forest, in Cameroon. The income-elasticity analysis showed that, contrary to "modern" fuels that are the oil and the gas which are normal goods, the...

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...

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”
Provedor de dados: 31
Autores: 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,...

DEMAND FOR FOOD QUANTITY AND QUALITY IN CHINA
Provedor de dados: 31
Autores: 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.

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
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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...

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.

Autores: 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.

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.

Relationship between the Unemployment Rate and the Demand for Orange Juice
Provedor de dados: 31
Autores: 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.

A recent study by Dong and Leibtag found coupons were effective in increasing fruit and vegetable demand.  The current study supports these finding for the OJ product group.  The analysis focused on the informational/advertising or demand shift impact of coupons, as opposed to the price impact which could not be determined since data on prices were a weighted average for coupon users and non-users.  The results indicate a 6% increase in OJ gallons sales when coupons are used. The coupon variable used in the analysis, however, measures the extent of coupon usage but not intensity. As such, the results provide a partial view of the impact of coupons and further analysis on data that also includes some measure of intensity is needed to more fully evaluate...

This variable was modeled through its impact on marginal utilities via "adjusted" prices, following theoretical work by Basmann and Barten, among others. Results show that the female labor participation has negatively impacted the demands for citrus, while positively impacting the demands for other fresh fruit.

Public Policies and the Demand for Vegetables
Provedor de dados: 31
Autores: Gustavsen,   Geir Waehler; Rickertsen,   Kyrre.
Increased consumption of vegetables may reduce obesity and the prevalence of cardiac diseases and cancer. Norwegians consume less vegetables than nutrition experts recommend and the per capita consumption is lower than in most European countries. To investigate the causes of low consumption, a two-step approach is used to estimate the demand segmented by nine different household types. In the first step, a probit model is estimated to investigate the decision whether to purchase traditional vegetables, salad vegetables, and industrially processed vegetables. Conditional on purchase, an almost ideal demand model is used to model how much to purchase. The own-price elasticities and total expenditure elasticities are high for traditional and industrially...

The Estimation of Food Demand Elasticities in Canada
Provedor de dados: 31
Autores: Pomboza,   Ruth; Mbaga,   Msafiri Daudi.
Changing consumer and market demands is an important driver behind the challenges and opportunities that are facing the agriculture and agri-food sector in Canada and that will influence the sector's profitability and competitiveness in the future. It is therefore important to understand developments in the consumer demand for agriculture and agri-food products. The report provides updated demand elasticities for fourteen food groups in Canada. The estimates are useful for conducting analysis of the changing structure of the agriculture and agri-food sector and can help quantify the impacts that changes in economic variables and policies that impact those economic variables might have.

Obesity and Nutrient Consumption: A Rational Addiction?
Provedor de dados: 31
Autores: Richards,   Timothy J.; Patterson,   Paul M.; Tegene,   Abebayehu.
Widespread obesity in the U.S. is a relatively recent phenomenon, reaching epidemic proportions only in the last 15 years. However, existing research shows that while calorie expenditure through physical activity has not changed appreciably since 1980, calorie consumption has risen dramatically. Consequently, any explanation of obesity must address the reason why consumers tend to overeat in spite of somewhat obvious future health implications. This study tests for an addiction to food nutrients as a potential explanation for the obesity epidemic. Specifically, we use a random coefficients (mixed) logit model applied to household scanner data to test a multivariate version of the rational addiction model of Becker and Murphy and Chaloupka. We find evidence...

TESTING AGGREGATION WITHOUT SEPARABILITY IN MEAT DEMAND: AN INVESTIGATION OF THE GENERALIZED COMPOSITE COMMODITY THEOREM
Provedor de dados: 31
Autores: Davis,   George C.
In the estimation of aggregate meat demand systems, weak separability is often a maintained assumption.  However, only a few studies have tested and failed to reject this assumption.  Recently, Lewbel (1996) developed a generalized composite commodity theorem (GCCT) that is less restrictive than weak separability.  In this study, a data set in which the weak separability conditions for aggregation have been rejected is reconsidered to determine if aggregation can be based on the GCCT.  Some subtleties of Lewbel's testing procedure that are not discussed by Lewbel are considered, and the fundamental problem of formulating aggregates prior to conducting tests for aggregation is addressed.

An Assessment of Dynamic Behavior in the U.S. Catfish Market: An Application of the Generalized Dynamic Rotterdam Model
Provedor de dados: 31
Autores: Muhammad,   Andrew; Jones,   Keithly G.
The generalized dynamic Rotterdam model was used in estimating U.S. demand for disaggregated catfish. The overall goal was to examine habit persistence in consumption and to determine the adjustment process in demand. Results indicated that it took up to 1 month for catfish-product demand to fully adjust to changes in expenditures and prices. Additionally, habit persistence played a role in demand where present consumption of a given product was positively affected by past consumption of that product. Consequently, U.S. catfish demand was significantly more elastic in the long-run.

Factors Influencing Demand for a Producer-Owned Beef Retail Outlet
Provedor de dados: 31
Autores: Lusk,   Jayson L.; Cevallos,   Edgar.
As the farm-to-retail price spread continues to grow, come cattle producers a beginning to consider integrating into the retail sector. Such a venture would require large investments in capital with uncertain return. This study seeks to determine the potential success of a stand-alone retail outlet selling “all natural” beef in an affluent area of Jackson, MS. Using choice-based conjoint analysis, demand for the new retail outlet is modeled as a function of the beef price at the store, distance of the store from consumers’ homes, distance of the store from consumers’ typical grocery store, and price of beef at substitute grocery stores. Simulation results suggest the proposed outlet could be a profitable venture, depending upon location and beef price.

U.S. Honey Supply Chain: Structural Change, Promotions and the China Connection
Provedor de dados: 31
Autores: Ward,   Ronald W.; Boynton,   Bruce.
Honey is a by‐product of the pollination of plants and essential to almost all agricultural plant product. Demand for honey provides a partial compensation for the pollination services. Hence, programs to support honey demand such as promotions are potentially very important to the agricultural sector as well as the honey industry. Honey is utilized for table consumption and for manufacturing and both U.S. domestic and foreign honey imports both contribute to the U.S. honey availability. Econometric models are estimated showing the domestic table‐use and manufacturing demand with the models explicitly incorporating the effects of generic promotion of honey. Rates-of‐ return to the U.S. honey promotion programs are estimated with rates assigned to domestic...

Autores: Wolfe,   Kent; Barefield,   Alan.
The transition from agricultural producer to agribusiness entrepreneur is littered with obstacles not associated with traditional farming operations. Producers are typically faced with an established market for their products as well as defined production practices and budgets. These familiar industry institutions are not available for use in the agribusiness environment. As a result, entrepreneurs are faced with new, unfamiliar situations that can significantly affect the success of their proposed or fledging business.

We apply the Berry, Levinsohn and Pakes (1995) market equilibrium model (BLP) to data from 30 brands of beers sold in 12 U.S. cities over 20  quarters (1988-92) to estimate the consumers’ taste for beer characteristics (price, alcohol content, and calories) as well as for the cultural region of origin (USA, Anglo-European, Germanic, and countries bordering the U.S.).  Consumer heterogeneity is allowed with respect to age, income and gender. Overall we end up with 7,200 beer brand observations (30x12x20) and 13,920 (58 random draws x 12 x 20) consumer observations. Empirical results indicate that indeed there is home bias with respect to European beers and somewhat less so with respect to beers from bordering countries (Mexico and Canada). Home bias is more...

Autores: Ladegard,   Gro; Romstad,   Eirik.
This paper addresses the coordination and innovation issues needed for promoting value added at the rural and regional level. There are two sides to value added: the ability to meet consumer demand, and to identify least cost ways of supplying the demanded goods. Human and social capital plays an important role on both sides. At the municipality level the supply side issues are complex. First, because the production space has far more dimensions than for the single entrepreneur. Second, because the value of some goods and services produced depend on what other goods and services that is available. On the supply side networks are important to solve the coordination issues, while networks for identifying and understanding consumer preferences are important...

The Korean livestock industry is currently facing the critical challenge of the market liberalization trend under the World Trade Organization. This study analyzes the consumption behavior of meat and fish products in Korea, by estimating the Linear Approximate Almost Ideal Demand System (LA/AIDS). The empirical results indicate that beef imports in Korea would increase in the future under trade liberalization. If cheap and better quality imported beef are introduced to Korean consumers, Hanwoo (Korean domestic cattle) beef would not maintain its market share.  Key words: Meat, fish, trade liberalization, per capita consumption, demand, separability, and price elasticity.

European Demand for Orange Juice

Autores: Brown,   Mark G.
The demand for OJ in Europe, and in particular the own-price elasticity of demand, has been difficult to estimate due to lack of good data.  Europe, however, is the largest OJ market in the world (USDA, Foreign Agricultural Service), and cannot be ignored in analyzing the U.S. and Florida OJ situations, given OJ is an internationally traded commodity.  Thus, estimates of the impacts of factors such as own-price on Europe’s OJ demand are critical for understanding the market.  The estimates in this study, although rough, provide some guidance for the magnitude of the price response in Europe, but to keep them in perspective, they are based on a relatively small number of observations and a proxy variable, suggesting that, as more and hopefully better data...

AN ECONOMETRIC ANALYSIS OF DEMAND FOR MEAT AND FISH PRODUCTS IN KOREA
Provedor de dados: 31
Autores: Jung,   Jione; Koo,   Won W.
This study analyzes the structure of Korean meat and fish product demand.  The Linear Approximate Almost Ideal Demand System (LA/AIDS) is used to estimate Korean meat and fish demand. Since the expenditure term is endogenous, the three-stage least squares (3SLS) estimator is used to estimate the demand system. Empirical results indicate that beef imports would increase with increases in per capita income. If imported beef becomes less expensive as a result of the trade liberalization policy adopted by the Korean government, Hanwoo beef would not be competitive and could lose its market share. Pork and chicken would be able to maintain market shares, but most fish products would lose market shares.

WHOLESALE DEMAND FOR USDA QUALITY GRADED BOXED BEEF AND EFFECTS OF SEASONALITY
Provedor de dados: 31
Autores: Lusk,   Jayson L.; Marsh,   Thomas L.
This study quantifies the differential in demand between different USDA quality grades of beef and the interaction between quality graded beef and other meats. We provide estimates of meat retailer own and cross price demand elasticities for USDA Choice and Select boxed beef.  Results indicate that meat retailers have more elastic demand for lower quality graded beef. Seasonal analysis indicates demand for both beef quality grades becomes highly price inelastic during the summer “"cook-out"” months. The two beef quality grades are strong substitutes during the fall and winter. However, Select beef is not a substitute for Choice beef in the spring and summer.

A variation of the household production theory was used to select relevant explanatory variables for the demand for convenience foods.  A convenience food index was used to measure the convenience in food preparation.  Because of the nature of the measure of convenience, the tobit regression technique was used to examine the importance of these explanatory variables to the demand for convenience foods.  Results show that the presence of children in a household increases the demand for convenience, especially in those households that have children of different age groups.  Results show that the number of end dishes eaten is positively related to the demand for convenience foods and primary users of convenience foods are non-black, single, and higher income...

HOW LARGE ARE NON-BUDGET-CONSTRAINT EFFECTS OF PRICES ON DEMAND?
Provedor de dados: 31
Autores: Heffetz,   Ori; Shayo,   Moses.
Elementary consumer theory assumes that prices affect demand only because they affect the budget constraint (BC). By contrast, several models suggest that prices can affect demand through other channels (e.g. because they signal quality). This alternative conjecture is consistent with evidence from marketing studies. However, neither theory nor evidence is informative regarding the magnitude of non-BC effects. The key econometric challenge arises from the fact that a change in prices typically also changes the BC. This paper uses a lab and a field experiment to disentangle BC from non-BC effects of prices on demand. In our lab experiment we find that, consistent with marketing evidence, prices positively affect stated willingness to pay. However, when...

We use panel data from two experiments conducted five months a part to investigate the stability of individual preferences and aggregate demand for five types of fish. Even though the bids in the two experiments are positively correlated, they clearly suggest that the individual preferences are unstable. This may be explained by internal desire for variety or by external effects such as new relevant information, seasonality in preferences, changes in the quality of the fish, and changes in the market price of fish. However, the aggregate demand curves of the participants are stable when we control for changes in the perceived quality of the fish and price expectations of the participants. In other words, the stability is generated by aggregation rather...

Provedor de dados: 31
Autores: Muhammad,   Andrew; Jones,   Keithly G.; Hahn,   William F.
As U.S. lamb imports increased relative to domestic production, and the relative share of chilled to frozen lamb imports increased, importers of chilled lamb have become less responsive to domestic and import prices, while the direct opposite is the case for frozen lamb imports. From 1990 to 2003, chilled lamb imports from Australia and New Zealand became less and less responsive to U.S. prices, and frozen imports became more responsive. Unconditional own-price elasticities also show that, over time, imports of chilled lamb became less responsive to import prices while frozen imports became more responsive to import prices.

Using data for 2002-2005 on a representative survey of French farms (FADN-RICA), we investigate the different factors that lead farmers to insure against crop risk. Our analysis takes into account a mix of both standard individual, financial and agricultural criteria. Cross-sectional and longitudinal analyses as well as logistic regressions underline the main differences between insured and non-insured farms. Compared to non-insured farms, we find that insured farms present greater financial and agricultural sizes, a more diversified production and have been motivated by the occurrence of recent catastrophic climatic events. Although essential in the cross-sectional analysis, the influence of financial parameters in the decision to insure is mitigated. On...

ABSTRACT Unlike some countries, Brazil has a predominantly hydraulic energy matrix, a clean and renewable source. But, in recent years, both the non-renewal of the normal volumes of water in the reservoirs and the lack of consciousness in the consumption of water and energy have placed the country in a critical state of energy supply leading to many intensive policies to reduce its consumption. In contrast, energy from Photovoltaic (PV) on-Grid Systems has grown dramatically in recent years. In this sense, this study presents an analysis of the contribution of the energy generated by a PV on-Grid Systems to be installed in CINDACTA II, in order to make re-contracting a lower demand possible and also reduce electric energy consumption and its cost.
