Optimal investment rules are developed for a producer agency investing in domestic-market generic advertising, export market promotion, and cost-of-production-reducing research. These rules are derived assuming either maximization of producers' surplus or social surplus. The form of the optimality rules differs according to which objective is pursued. Fixed producer agency budgets are also allowed by incorporating a constraint limiting total expenditure on the three activities. Addition of such a constraint substantially alters the structure of the optimal investment rules. Differences in these rules highlight the importance of accounting for the financing mechanism when modeling optimal checkoff fund investment decisions. Optimality rules are simulated using data for the Canadian beef sector. Results suggest historic underinvestment in domestic-market generic advertising but overinvestment in export market promotion. Sensitivity of simulation results underscores the difficulty in assessing optimality of historic producer investment in cost-of-production-reducing research.  相似文献

An optimal advertising rule is derived for a good sold in an open market (beef) when a related substitute good (chicken) is production rationed and whose imports are subject to trade restrictions. Such a rule is developed using a multi-market equilibrium displacement model that reflects demand interrelatedness, open trade of the advertised good (beef), with rationed production and restricted trade of the related good (chicken). The optimal rule nests earlier optimal advertising rules under a variety of conditions. Results underscore the importance of accounting for cross-product advertising effects. When these effects are present (absent), the optimal generic beef advertising intensity in Canada is shown to fall (rise) with elimination of supply management in Canada's chicken sector.
L'auteur dérive une règie sur l'optimisation de la publicité pour un produit vendu sur un marché libre (bœuf) en présence d'un produit de substitution rationné dont on restreint les importations. Pour parvenir à une telle règie, l'auteur a utilisé un modèle de déplacement du point d'équilibre sur un marché multiple illustrant les liens entre la demande des produits concernés, le libre-échange du produit faisant l'objet de la publicité (bœuf) et la restriction de la production et des importations du produit apparenté (poulet). La règie d'optimisation englobe les règles antérieures sur l'optimisation de la publicité dans diverses situations. Les résultats soulignent qu'il est important de prendre en compte les retombées de la publicité sur les autres produits. Au Canada, en présence (absence) de telles retombées, le degré optimal de publicité générique sur le bœuf diminue (augmente) avec l'abolition de la gestion de l'offre de poulet.  相似文献

This study considers the factors that explain the consumption of food and beverages with functional ingredients to avert or offset health problems. We use an instrumental variables Poisson regression model to deal with the endogeneity of perceived health status in functional ingredient use. The first stage results indicate that perceived health status is associated with attitude towards functional foods, food consumption motives and information seeking and being female. The second stage results suggest that individuals who consume more functional ingredients tend to have a positive attitude towards functional foods, are novelty‐seeking, female and older. As expected, consumption of functional ingredients is more likely when consumers’ self‐reports indicate that they are aware of functional foods’ nutritional value and the link with their own health. Consistent with previous research, most of the socio‐demographics are poor predictors of functional ingredient consumption.  相似文献

In 21st century agriculture, standards are increasingly used to define new food products, such as organic food and fair trade. In some cases these standards are privately determined but in other cases they have been established by governments. Indeed, the Government of Canada recently announced its organic food regulations. A key dimension of the policy process involves choosing which standards are to be used to govern the production of organic food. Unfortunately, decision makers faced with these choices know very little about how the public values the various standards that could be used to define organic. This study evaluates Canadian consumers' preferences for different organic standards. Standards pertaining to pesticide‐residue testing, product origin specifications, the standard setting agency, and standard monitoring agency are evaluated using a conjoint method. Key results suggest that consumers place a high value on a pesticide standard that involves regular testing of the end product and that they prefer an organic food standard to include a rule that limits where the good is produced. En agriculture en ce 21e siècle, des normes sont de plus en plus utilisées pour définir de nouveaux produits alimentaires tels que les aliments biologiques et les aliments issus du commerce équitable. Dans certains cas, ces normes sont établies par des organismes privés, et dans d'autres cas, elles sont établies par les gouvernements. Dernièrement, le gouvernement du Canada a annoncé son Règlement sur les produits biologiques. Un élément clé du processus d'élaboration des politiques consiste à choisir les normes qui s'appliqueront à la production d'aliments biologiques. Malheureusement, les décideurs à qui reviennent ces choix en savent très peu sur les valeurs que le public accorde aux diverses normes qui pourraient être utilisées pour définir le terme «biologique». La présente étude évalue les préférences des consommateurs canadiens concernant les diverses normes sur les produits biologiques. Les normes sur l'analyse des résidus de pesticides, les spécifications sur l'origine du produit, les organismes de normalisation et les organismes de surveillance sont évaluées à l'aide d'une méthode conjointe. Les résultats fondamentaux montrent que les consommateurs accordent une grande importance à une norme sur les pesticides qui exige des analyses régulières du produit final et qu'ils préfèrent une norme sur les aliments biologiques qui inclut un règlement sur l'origine du produit.  相似文献

Most researchers examining poverty and multilateral trade liberalizationhave had to examine average, or per capita effects, suggestingthat if per capita real income rises, poverty will fall. Thisinference can be misleading. Combining results from a new internationalcross-section consumption analysis with earnings data from householdsurveys, this article analyzes the implications of multilateraltrade liberalization for poverty in Indonesia. It finds thatthe aggregate reduction in Indonesia's national poverty headcountfollowing global trade liberalization masks a more complex setof impacts across groups. In the short run the poverty headcountrises slightly for self-employed agricultural households, asagricultural profits fail to keep up with increases in consumerprices. In the long run the poverty headcount falls for allearnings strata, as increased demand for unskilled workers liftsincomes for the formerly self-employed, some of whom move intothe wage labor market. A decomposition of the poverty changesin Indonesia associated with different countries' trade policiesfinds that reform in other countries leads to a reduction inpoverty in Indonesia but that liberalization of Indonesia'strade policies leads to an increase. The method used here canbe readily extended to any of the other 13 countries in thesample.  相似文献

A North American beef industry model incorporating a hypothesized relationship between beef advertising and processor oligopoly power was estimated and used to evaluate various advertising options faced by Canadian cattle producers. Generic and branded advertising significantly increased Canadian and U.S. beef demand. As well, historic generic beef advertising expenditure in Canada returned a net profit to Canadian producers. However, additional Canadian producer investment in generic beef advertising in Canada lowered producer profits, while investment in Canadian or U.S. brand advertis- ing or U.S. generic advertising generated positive net returns.
Nous avons construit un modèle mathématique pour le secteur nord-américain de la viande de boeuf, incorporant un rapport hypothétique entre la publicité du produit et le pouvoir oligopolistique au niveau du secteur de la préparation-transformation. Nous avons utilisé le modéle pour évaluer diverses options de publicité auxquelles font face les producteurs de bavins canadiens. La publicité générique et la publicité de marque ont procuré un accroissement de la demande de viande bovine tant au Canada qu'aux États-Unis. De plus, les dépenses engagées au cours des années au chapitre de la publicité générique de la viande bovine au Canada ont valu aux producteurs canadiens un bénéfice net. En revanche tout accroissement des investissements consacrés à la publicité générique par ces producteurs s'est soldé par une baisse des profits à la production, alors qu'aux États-Unis il se révélait en général rentable. Par aileurs, l'intensification de la publicité de marque s'est montrée rentable dans les deux pays.  相似文献

Using stated choice data collected by experimental design with repeated choice tasks, this study developed an approach to quantify the position-dependent order effects on the prediction of preferences and marginal willingness to pay for product attributes. Results showed that repeated choice tasks allow learning to occur. Models with order effect adjustments showed significant improvements in goodness of fit. Attribute-specific polynomial trends showed the best fit among all models, which could possibly be explained by respondents’ familiarity and sensitivity to different product attributes. Repeated-choice experiments have a good potential to capture consumer preferences more accurately than the single-choice design. But order effects need to be taken into account for preferences and market prediction.  相似文献

Motivated by a lack of Engel flexibility in commonly used demand systems, Rimmer and Powell developed a new demand system. This system, referred to AIDADS, is implicitly, directly additive, possesses marginal budget shares and thus Engel elasticities, that vary nonlinearly with expenditure such that predicted budget shares are restricted to the [0,1] interval. Due to these attractive Engel properties, AIDADS represents a significant contribution to the literature on demand analysis. This paper presents an alternative estimation procedure to the one used by Rimmer and Powell and examines its properties via a case study. The proposed approach avoids a linear approximation employed in Rimmer and Powell's estimation framework. Based on a small Monte Carlo study, it appears that the approach produces more accurate estimates of the parameters and Engel elasticities.  相似文献

This paper analyzes the effect of firm and other characteristics on the incidence and intensity of improved financial performance among non-farm microenterprises in Ghana, using data from the 1998/1999 Ghana Living Standards Survey (GLSS 4). The results indicate that firm characteristics, including urban and regional location, significantly affect the incidence and intensity of improved performance, but entrepreneurial characteristics are unimportant. The firm’s capital stock does not affect the propensity and intensity of better performance, reflecting that the value of assets owned is low and insufficient to have a measurable impact on enterprise productivity and performance.  相似文献
