Análise da participação da agropecuária no PIB dos EUA de 1960 a 2001 AgEcon
Brugnaro, Ricardo; Bacha, Carlos Jose Caetano.
This paper analyses the evolution of agriculture’s participation in the US gross domestic product (GDP) from 1960 to 2001. An econometric model is run in order to identify the main variables that determine this participation. From 1960 to 2001, there is a downward trend of agriculture’s participation in the US GDP with a break from 1971 to 1973, in other words, agriculture’s participation in the US GDP decreased from 1960 to 1970, increased from 1971 to 1973 and decreased again from 1973 to 2001. The 1971-1973´s break in the downward trend of agriculture’s participation is econometrically proved. Dataset organized in graphs show grain and meat production steadily enlarged from 1970 to 2001, what is closely related to the productivity increase and federal...

Consumer behaviour in agricultural direct marketing AgEcon
Heer, Ines M..
Scandals in the food production industry have caused an uncertainty about quality and innocuousness of food for many consumers. This resulted in a strong risk perception of consumers at the point of sale. The direct marketing of products by farmers can be an important way to strengthen consumer confidence. In this contribution, buying behaviour is examined by an observation and a following interview. We develop an econometric model about the number of bought products and the proposition of marketing strategies which can be recommended to farmers involved in direct marketing.

Consumer incentives to comply with nutritional recommendations – an economic approach AgEcon
Dejgaard Jensen, Jorgen; Hansen, Aslak H.; Fagt, Sisse; Velsing Groth, Margit.
Inappropriate diets have been found to cause long-term health problems in most industrial and post-industrial countries worldwide. Despite the existence of dietary guidelines in many countries – and widespread familiarity with these guidelines – large shares of the populations do not comply with these guidelines. The objective of the paper is to investigate economic explanations for non-compliance quantitatively, focusing on consumers’ perceived value of reduced freedom of choice, if they should comply with the dietary recommendations. The paper establishes and econometric simulation model for Danish food consumers, which is used for calculating these economic welfare losses, as well as the contribution to these losses from individual recommendations....

Determinants of Land-Use Change In the United States 1982-1997 AgEcon
Lubowski, Ruben N.; Plantinga, Andrew J.; Stavins, Robert N..
Changes in the use of land in the United States produce significant economic and environmental effects with important implications for a wide variety of policy issues, including protection of wildlife habitat, management of urban growth, and mitigation of global climate change. In contrast to previous descriptive and qualitative analyses of the trends in national land use, this paper uses an econometric approach to isolate the importance of historical changes in land-use profits and key government policies in determining national land-use changes from 1982 to 1997. The policies we examine are the Conservation Reserve Program (CRP) and total government payments to crop producers. We estimate a national-level discrete choice model of changes among the major...

Differentiated Food Taxes as a Tool in Health and Nutrition Policy AgEcon
Smed, Sinne; Jensen, Jorgen Dejgaard; Denver, Sigrid.
The purpose of the present study is to analyse the effects of using economic policy tools in nutrition policy, e.g. introduction of specific taxes on unhealthy food components or differentiated VAT on foods. The effects of such regulation instruments are demonstrated using Denmark as an illustrative case. A model concept combining econometric models of food consumption behaviour for different socio-demographic groups with a model for conversion between food consumption and nutrient intake is developed. The socio-demographic effects of four different tax or subsidy regulation schemes are investigated.

Documentation of a Dynamic and Simultaneous Econometric Model of the U.S. Dairy Industry AgEcon
Bailey, Kenneth W..
The objective of this report is to publish a monthly forecasting tool of the U.S. dairy industry. This model forecasts the milk supply as well as the supply and demand for American cheese, Other cheese, butter, nonfat dry milk, and dry whey. Trade is presently exogenous to the model, but can be endogenized at a later date. The principal use of the model will be for forecasting purposes, thus we settled on a monthly frequency for the data. We delve into the complexities of the U.S. dairy industry using rich data sources. Our objective is clearly focused on developing an initial forecasting tool.

Implications of EU Enlargement for Agricultural Markets in the New Member States AgEcon
van Leeuwen, Myrna; Bartova, Lubica; M'Barek, Robert; Erjavec, Emil.
The paper presents an analysis of the impact of the Common Agricultural Policy implementation on the agricultural markets of the eight new EU Member States. The study is based on the AGMEMOD (AGricultural MEmber states MODelling) national econometric models. Two scenarios are simulated for each country. The "Baseline" scenario assumes the implementation of the Single Area Payment Scheme until 2008 and the subsequent introduction of the Single Payment Scheme from 2009 onwards. Complementary national direct payments would remain in force until 2013. The second scenario assumes the full decoupling of direct payments from 2007 and the introduction of modulation from 2013 onwards in the 2004 enlargement new Member States (EU-8). The baseline scenario...

Modelling Risks in the Salmon Industry and Markets AgEcon
Asheim, Leif Jarle; Lien, Gudbrand D.; Richardson, James W.; Tveteras, Ragnar; Veggeland, Frode.
The paper proposes developing a trade model for salmon to assist in discussions and negotiations of current international salmon trade issues and major risk problems facing the salmon industry. Two modeling approaches are discussed: 1) developing a traditional equilibrium trade programming model designed to maximize total welfare across all model regions by solving for a medium-term price that balances the amount of salmon supplied by the world region to the among processed and consumed by this region; and 2) developing an econometric stochastic simulation model based on linear or non-linear equations. Some disadvantages and weaknesses of the programming model are discussed, whereas the econometric model needs further exploration and consideration. The...

Spanish Consumers' Attitudes and Acceptability towards GM Food Products AgEcon
Angulo, Ana Maria; Gil, Jose Maria.
The objective of this paper is to analyse consumers’ attitudes and acceptability of GM food products in Spain. From the methodological point of view, a three-equation model of consumer behaviour is estimated assuming a kind of causal chain among the degree of knowledge, attitudes and buying intentions. Explanatory variables include socioeconomic characteristics of respondents as well as endogenous variables of the previous equations. The model provides a better knowledge of how attitudes and buying intentions towards GM food are formed. Higher educated consumers, more concerned about labelling information and less about price, and regular buyers of organic foods show a higher (not necessarily better) knowledge on GM technology and its consequences....

The Potential Effects on United States Agriculture of an Avian Influenza Outbreak AgEcon
Brown, Scott; Madison, Daniel; Goodwin, Harold L., Jr.; Clark, F. Dustan.
The U.S. poultry industry has spent considerable resources to date preparing for an outbreak of avian influenza in this country. This research quantifies the potential effects of two alternative avian influenza scenarios on the poultry industry. In addition, this research looks at effects on other agriculture sectors including the loss of feed demand from an outbreak and the impacts on aggregate measures like farm income and consumer food expenditures. The economic sector model maintained by the Food and Agricultural Policy Research Institute (FAPRI) is employed for these scenarios.
