Decision Strategy and Structure in Households: A “Groups” Perspective

From a practical perspective, (arguably) most consumer decisions are not made in isolation of the households in which consumers are inserted, yet we commonly treat them econometrically as if they were. The purpose of this workshop was to take some initial steps in defining needed research in household decision making that structurally accounts for goal sharing, utility interdependence, taste heterogeneity, choice set formation, power structures, group size and composition, and so forth. We also considered conditions under which aggregation of tastes, utility and choices might occur and make sense from both behavioral and modeling perspectives.     

AN INTEGRATED ECONOMETRIC MODEL OF THE CANADIAN LIVESTOCK-FEED SECTOR*

Canadian econometric studies dealing with the livestock-feed sector have tended to concentrate on individual commodities, or on a particular component of the market equilibrium process. In this article an integrated model of the sector is presented which depicts the nature of commodity interactions both at the consumer level and the producer level. The feed sector was conceptualized primarily in terms of derived demand. The model contained a total of 82 equations, of which 64 were related to the livestock subsystem. The estimated model was subsequently used for predicting the impact of changes in selected instrumental variables on the livestock-feed sector.
Les dernières etudes économétriques canadiennes traitant du pâturage se sont concentrées sur les produits séparés on sur un composé particulier répondant au besoin commercial. Cet article présents un modèle intégré du secteur montrant la nature des actions réciproques entrc les produits au niveau du consommateur et du producteur. Le secteur pâturage est expliqué en fonction de la demande. Le modèle contenait 82 équations, 64 desquelles se rapportaient àľélevage; par conséquent le modèle est employé pour prédire ľinfluence dans les pâturages de changements opérés sur les composants choisis.
