Analysing Wine Demand With Artificial Neural Networks AgEcon
Gerolimetto, M.; Mauracher, Christine; Procidano, I..
In this paper we analyse wine demand in Italy using microdata. Instead of estimating a traditional parametric model (like AIDS) we employed artificial neural networks (ANN) and evaluate the elasticities using two different methods, specific for the non parametric framework. We compared the performances of the two methods to estimate elasticities and put in evidence the relevance of some demographic variables together with the usual economic ones, explaining the consumer's behaviour.

Consumption of dairy products in urban China: results from Beijing, Shangai and Guangzhou AgEcon
Fuller, Frank H.; Beghin, John C.; Rozelle, Scott.
Using urban survey data collected by the authors in 2001–02, this paper analyses demographics, cultural factors and purchasing behaviours influencing the consumption of fresh milk, yogurt, ice cream and powered milk in Beijing, Shanghai and Guangzhou, China. Results from estimation of a double-hurdle model of consumption show that income and marketing channels are the key determinants of milk consumption levels; however, education, advertising and convenience play a more important role in consumption of other dairy products. There is some evidence that milk powder, as a consumer good, may be becoming an inferior product in urban China. Finally, the survey data suggest that the growing sophistication of China’s retail sector is influencing consumption of...

Demand for Wine in Australia: Systems Versus Single Equation Approach AgEcon
Chang, Hui-Shung (Christie); Bettington, Nicholas.
The objective of the study is to estimate demand for wine in Australia, based on both the systems approach and the single equation approach. Both approaches consider demand for three categories of alcoholic drinks (beer, wine and spirits) in a seemingly unrelated regression framework to take account of cross-equation correlations. Time series data on retail price indexes and apparent per capita consumption of alcoholic beverages for Australia for the period 1975/76 to 1998/99 are used for econometric estimation. The results show that over the short run, beer and wine are necessities; however, over the long run, wine becomes a luxury good. Beer and wine are complements. Demand for all three beverages is price inelastic. The study also found that the...

EINE LOGIT-ANALYSE ZUR DIFFERENZIERUNG VON KÄUFERN UND NICHT-KÄUFERN VON SCHULMILCH IN DEUTSCHLAND AgEcon
Peter, Guenter; Salamon, Petra; Christoph, Inken B.; Weible, Daniela; Burgelt, Doreen.
Vor dem Hintergrund eines sinkenden Schulmilchkonsums in Deutschland stellt sich generell die Frage, welche Faktoren für die Kaufentscheidung von Schulmilch wichtig sind und, ob unterschiedliche Konsummuster für einzelne Gruppen existieren. Dieser Beitrag erweitert bestehende ökonometrische Erklärungsansätze um Schüler- und Haushaltscharakteristika. Dazu werden auf der Grundlage der Discrete Choice-Theorie zwei Konsummuster, die Gruppe der Schulmilchbesteller und die Gruppe der Nicht-Besteller, betrachtet. Mit Hilfe eines Logit-Modells werden Einflussfaktoren analysiert, die über das Konsummuster entscheiden. Als wichtige Faktoren kristallisieren sich die befürwortenden und ablehnenden Einstellungen der Schulkinder und ihrer Eltern gegenüber Milch und...

Fish and fishery products trade in Brazil, 2005 to 2015: A review of available data and trends Scientia Agricola
Barone,Rafael Simões Coelho; Lorenz,Evandro Kleber; Sonoda,Daniel Yokoyama; Cyrino,José Eurico Possebon.
ABSTRACT: Along the last ten years fish and fishery product trade in Brazil has been on a downward trajectory turning a profit of US$ 98.6 million in 2005 into a loss of US$ 1.25 billion by 2014. On the other hand, the country is a leading producer of grains and has the third largest animal feed industry in the world, which has added 5.5 million hectares of freshwater reservoirs and 3.5 million km2 of an exclusive marine economic zone in the same period, a sizable potential for development of the aquaculture industry. This study aims at unveiling strategies for the reduction of the deficit in the Brazilian seafood trade balance, based on critical analysis of the quantitative and qualitative characteristics of imported fishery products. The fish and fishery...

Food Scares and Demand Recovery Patterns: An Econometric Investigation AgEcon
Mazzocchi, Mario.
This paper aims to propose a flexible stochastic approach to measure the time pattern of a food scare, which does not require the inclusion of additional explanatory variables such as a media coverage indices and easily accommodates the reoccurrence of the same or different scares. We show the results of an application to Italian demand for beef and chicken, which has been affected by the BSE and dioxin scares over the last decade.

FRAGILITY IN DAIRY PRODUCT DEMAND ANALYSIS AgEcon
Maynard, Leigh J.; Liu, Deyu.
Several reasons justify the expectation of increasingly price elastic demand for dairy products. Using weekly scanner data, we find support for this hypotheses, but with wide variation in elasticity estimates across model specifications. The results demonstrate the need for more routine specification testing before basing recommendations on potentially fragile inferences.

ISSUES OF DEMAND SPECIFICATION AND INDUSTRY STRUCTURE IN TURKEYS AND BROILER CHICKENS AgEcon
Cheney, Laura Martin; Brown, A. Blake; Yamano, Takashi; Masterovsky, Michael.
Factors unique to the turkey industry suggest that conclusions concerning market structure and demand specification drawn from aggregate poultry data cannot necessarily be extrapolated to the turkey industry. The Wu-Hausman endogeneity test is used to examine demand specifications and industry structure specifically for turkey meat. In contrast to general poultry, quantity-not price-is found to be predetermined in demand models that use annual turkey data. Quarterly demand analysis suggests this result stems from biological cycles that limit a producer's ability to react to price change and the use of a weighted average for determining price and quantity.

Modelling physical quantities of food and nutrients consumed from aggregate data – with an application to Finland AgEcon
Irz, Xavier T..
Anticipating the impact of changes in economic incentives on dietary quality and nutritional health requires knowledge of how physical quantities of food consumed respond to price and income variations. A problem arises, however, because physical quantities are: 1- not consistent aggregates in demand models; and 2- not measured at final/retail level in national statistics. The paper develops a solution by establishing explicitly the theoretical link between composite demand and physical quantities, from which a novel empirical approach to the estimation of nutrient elasticities is derived. It is applied to Finnish aggregate data from the National Accounts and Food Balance Sheets over the 1975-2006 period, and the results are used to assess the potential...

On the Empirical Content of Demand Analysis AgEcon
Barten, Anton P..
Falsification of nontrivial empirical statements, of a statistical nature or not, is basically destructive. No wonder that it is rarely practiced. Rather than then abandoning a rejected null hypothesis, one tries to salvage it by looking for reasons why the rejection of an otherwise credible, plausible hypothesis occurs. One then attempts to modify the set-up in such a manner that formal rejection is avoided. Testing, in general, but specifically of nonnested hypotheses, can be seen as a kind of model selection. These issues are illustrated with examples from applied demand analysis: the testing of the homogeneity condition and of Slutsky symmetry and the choice of functional form for demand systems.

Quantifizierung der Preis– und Ausgabenelastizitäten für Nahrungsmittel in Deutschland: Schätzung eines LA/AIDS AgEcon
Wildner, Susanne.
Complete and consistent, i.e. theoretically appropriate demand systems have seldom been developed for Germany. Econometric food demand analyses have concentrated on single products and product groups. Generally, demand functions have been estimated using single equation methods. The purpose of this paper is to analyse the food demand in former West Germany on the basis of the Almost Ideal Demand System (AIDS) developed by DEATON and MUELLBAUER (1980). A two-stage demand system is based on data for the household type III gathered on a monthly basis during the period from 1966 to 1997. At a first stage, five aggregates of food (meats and fish; dairy and eggs; edible fats; cereals, fruits and vegetables; and other foods) and one non-food group are specified....

Relative Importance of Factors Affecting Customer’s Decisions to Buy Pick-Your-Own Versus Preharvested Fruit at North Carolina Farms AgEcon
Carpio, Carlos E.; Wohlgenant, Michael K.; Safley, Charles D..
This study identifies the most important factors affecting customers’ decisions to buy pickyour- own versus prepicked strawberries and muscadine grapes at direct-market operations in North Carolina. The relative importance analysis identified the region of location of the operations and prices as the explanatory variable explaining most of the variation observed in the customer’s decision to choose the type of fruit to purchase. The estimated price elasticities indicate that sales of each type of fruit are very sensitive to prices.

The Demand for Agritourism in the United States AgEcon
Carpio, Carlos E.; Wohlgenant, Michael K.; Boonsaeng, Tullaya.
Using data from the 2000 National Survey on Recreation and the Environment, this study explores factors affecting visits by the American population to farms and the economic value of the rural landscapes for farm visitors. The number of farm recreation trip visits was estimated to have own-price elasticity of -0.43 and an income elasticity of 0.24. Location of residence, race, and gender were found to be important determinants of the number of farm trips. The calculated consumer surplus is estimated at $174.82/ trip, of which $33.50 is due to the rural landscape.

The Estimation of Food Demand Elasticities in Canada AgEcon
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.

URBAN DEMAND FOR DAIRY PRODUCTS IN CHINA: EVIDENCE FROM NEW SURVEY DATA AgEcon
Fuller, Frank H.; Beghin, John C.; Rozelle, Scott.
In this paper we use 2001-2002 urban survey data we collected to analyze demographics, cultural factors, and purchasing behaviors influencing the consumption of fresh milk, yogurt, ice cream, and powered milk in urban areas of China. The data include frequency of consumption by product, location of consumption and purchase, exposure to advertising and foreign culture, and school milk programs. The variables serve as regressors in a double-hurdle model that examines the decision to consume or not to consume and the level of consumption. We also estimate consumption levels and participation equations with tobit and probit models.

URBAN HOUSEHOLD DEMAND FOR MEAT AND MEAT PRODUCTS IN NIGERIA: AN ALMOST IDEAL DEMAND SYSTEM ANALYSIS AgEcon
Ezedinma, Chuma I.; Kormawa, P.M.; Chianu, Jonas.
This study is based on micro level data on urban household food consumption and expenditure collected between 1999 and 2000 in three Nigerian cities. The LA/AIDS model, which allows the inclusion of demographic variables, was applied to a subset of the data on meat and meat products namely beef, mutton/goat, chicken, fish, eggs, and milk. Results indicate that urban demand for meat products will continue to increase as incomes improve, suggesting potential market opportunities especially for poultry. Intra-household demand patterns clearly indicate the importance of beef for children but contrary to expectations, there is a reduced demand for milk as the number of infants in urban households increase. The observed high income elasticity of demand for...

Urban water demand with fixed volumetric charging in a large municipality: the case of Brisbane, Australia AgEcon
Hoffmann, Mark; Worthington, Andrew; Higgs, Helen.
This paper uses suburb-level quarterly data to model residential water demand in Brisbane, Australia, from 1998 to 2003. In this system, residential consumption is charged using a fixed annual service fee with no water entitlement followed by a fixed volumetric charge per kilolitre. Water demand is specified as average quarterly household water consumption and the demand characteristics include the marginal price of water, household income and size, and the number of rainy and warm days. The findings not only confirm residential water as price and income inelastic, but also that the price and income elasticity of demand in owner-occupied households is higher than in rented households. The results also show that weather, particularly summer months and the...
