Bayesian Analysis for a Theory of Random Consumer Demand: The Case of Indivisible Goods

McCausland (2004a) describes a new theory of random consumer demand. Theoretically consistent random demand can be represented by a \"regular\" \"L-utility\" function on the consumption set X. The present paper is about Bayesian inference for regular L-utility functions. We express prior and posterior uncertainty in terms of distributions over the indefinite-dimensional parameter set of a flexible functional form. We propose a class of proper priors on the parameter set. The priors are flexible, in the sense that they put positive probability in the neighborhood of any L-utility function that is regular on a large subset bar(X) of X; and regular, in the sense that they assign zero probability to the set of L-utility functions that are irregular on bar(X). We propose methods of Bayesian inference for an environment with indivisible goods, leaving the more difficult case of indefinitely divisible goods for another paper. We analyse individual choice data from a consumer experiment described in Harbaugh et al. (2001).

La responsabilité de l'intermédiaire de marché et la protection du petit investisseur : à la recherche d'un certain équilibre

"Mémoire présenté à la Faculté des études supérieures en vue de l'obtention du grade de maîtrise, option droit des affaires"

Cosmopolitanism and confrontation : realizing consumer responsibility in a globalized marketplace

Ce mémoire explore des façons de conceptualiser la responsabilité dans des cas où des individus contribuent de façon peu significative à des torts collectifs éloignés. Pour contextualiser la discussion, la relation entre des actes de consommation et la perpétuation des « sweatshops » dans l’industrie des textiles et des chaussures est utilisée. Une approche basée sur les droits humains est déployée pour définir le tort qui est présent dans les usines de textiles et une conceptualisation de la connection est proposée selon la notion de la structure sociale. Guidé par la notion de « unstructured collective harms » proposée par Christopher Kutz, et en comparaison avec des notions de responsabilité qui mettent la responsabilité nationale en premier plan, les conclusions qui sont offertes ici sont centrées sur l’importance de la confrontation du consommateur pour remédier aux effets du problème d’action collective qui est au coeur de la création des torts collectifs lointains. Finalement, l’importance du cosmopolitanisme comme une façon de stabiliser des théories de responsabilité à travers les frontières est mis en évidence.

Nature et impacts juridiques de la certification dans le commerce électronique sur Internet

Le sujet sur lequel porte la présente étude est inspiré de la problématique à la base du développement du commerce électronique : la confiance. En effet, l’accroissement exponentiel du nombre d’internautes et des sites Web commerciaux pose un sérieux problème à ce niveau. Ces sites présentent au public une information et des services divers, mais peu vérifiables. Ainsi, le principal obstacle au développement du commerce électronique avec les particuliers est le manque de confiance qu’inspirent les lieux visités. En effet, comment savoir si l’entreprise existe, quelles sont ses politiques concernant la sécurité ou la gestion des renseignements personnels, etc. La vérification et la certification des sites apparaissent comme une solution de plus en plus attrayante et utilisée pour ajouter cet élément de confiance. Déjà, de nombreux sceaux de qualité sont apparus sur les sites commerciaux. Certains sceaux portent sur la confidentialité tandis que d’autres ciblent la protection des consommateurs. La certification peut provenir de la compagnie même, d’un tiers certificateur ou d’un organisme public. Ces éléments constituent des balises et repères importants pour le consommateur sur Internet. Toutefois, les incidences légales sont multiples et certains concepts demeurent flous. Pour apporter une réponse à ces questions, nous définirons le concept de certification des sites Web et ses enjeux dont plus particulièrement la problématique de la confiance des consommateurs. Les différents objets de la certification seront analysés, tant au niveau de l’entité, du contenu du site que de la dimension transactionnelle de celui-ci. Les processus possibles et les impacts de la certification occupent la seconde partie du travail. Il s’agit d’examiner successivement les étapes menant à la certification, soit l’établissement des standards, de l’évaluation de l’entité et de la certification elle-même. L’analyse des impacts de la certification, tant sur le plan de la portée, de la responsabilité légale et des effets sur la concurrence de la certification constitue quant à eux, l’aboutissement de la recherche, soit de savoir quel est l’impact juridique d’un tel mécanisme. Le but de la recherche est de permettre au lecteur de mieux cerner ce phénomène de l’utilisation de la certification sur Internet avec ses avantages et ses limites. Certes, cet outil peut s’avérer très utile pour bâtir la confiance des consommateurs, promouvoir l’essor du commerce électronique et constituer une forme d’autoréglementation. Toutefois, mal utilisé ou mal encadré, il peut engendrer l’effet inverse et détruire cette confiance si fragile à construire dans un environnement dématérialisé.

The Lack of Credibility on the Web and Its Legal Ramifications Under Quebec’s Consumer Protection Act

Cet article examine les complications juridiques mises de l’avant par la récente étude « Credibility on the Web » publiée par le groupe Consumers International. Selon cette étude, plusieurs sites n’étant affiliés à aucun manufacturier ou vendeur font leur apparition sur le Web afin d’offrir aux consommateurs certaines informations générales concernant divers produits et services. Malheureusement, puisque ces sites sont gérés par des tiers n’étant pas partie à la relation consommateur-commerçant, une nouvelle problématique juridique peut être mise de l’avant : quelle protection accorder aux consommateurs eu égard à leurs achats effectués suite aux mauvais conseils de ces sites ? Ce texte vise à mettre sur pied les fondements d’une telle problématique selon le droit de la consommation québécois et à envisager certaines pistes de solutions possibles concernant les recours que pourraient avoir les consommateurs contre de tels sites.

Buyer information and brand Choice behavior in markets with asymmetries

This thesis Entitled Buyer information and brand choice behaviour in markets with asymmetries.The period of transition set in by globalization and liberalization has ensued a onsiderable degree of homogeneity with western societies with respect to quantity and quality of goods and services.The study is aimed at finding out how the buyers adapt to the prevalent complex and dynamic market configuration by taking an archetypical situation of information gathering and brand- choice decision of select household consumer durables.The study was based on a set of 301 sample respondents who were either first time purchasers or repeat purchasers for household use, of the items under study in the sample area comprising of rural, urban and semi-urban areas. Data were collected using interview schedule and analysis of the same was done with standard statistical computer programs.Buyer confidence as perceived by buyers with respect to information acquisition and brand-choice represents the felt competence to effectively function in the market.In general, lower levels of education, income and occupation showed lower levels of search. The oldest were also low searchers. The repeat purchasers of the product searched less than the first purchasers. The most important source of information was word of mouth or information from others followed by television advertisements. The least important source of information was billboards, displays and similar forms of advertisements.The second factor is characterized by items representing ‘social attributes’ like, use by many others, use by peers, recommendation by significant others and reputation of the brand. The third factor represents ‘susceptibility to incentives and promotions’.

Legal Protection for Consumer of Pharmaceutical Products

The overall focus of the thesis involves the legal protection for consumers of pharmaceutical products.The work on “Legal Protection for Consumers of Pharmaceutical Products” is undertaken to study the legal framework that is existing for this purpose and the functioning of regulating mechanism that is envisaged under it. The purpose of the study is to analyse how far these measures are effective in adequately protecting various aspects of consumer interest. Methodology adopted for the study is analytical.The present study revealed that the theory of freedom of contract is only an ideal relevant when the parties are assumed to be on equal footing.In a more complicated social and economic society, it ceased to have any relevance. Many countries in the world enacted legislations to protect the consumers of pharmaceutical products.The meaning of ‘consumers of drugs’ provided in the law is inclusive and not exhaustive one. The definition of ‘drug’ as interpreted by the courts is comprehensive enough to take in it not only medicines but also substances. The meaning of the word substances has been widened by the interpretation of the courts so as to include all the things used in treatment.The definition of the word ‘consumer’ has been liberally interpreted by the courts so as to provide protective net to a large section of the public.The studies subsequent to this report also revealed that there is a shortage of essential drugs necessary to cure local diseases like tuberculosis and malaria where as drugs containing vitamins and other combinations which are more profitable for the manufacturers are produced and marketed in abundance.The study of the provisions in this regard revealed that the duty of the drug controlling authorities is confined to scrutinize the data of the clinical test already conducted by the sponsor of the drug.Study of the clinical trial procedure under the U.S. law revealed that there is a continuous supervision over clinical trials and controls are provided on the treatment use of an investigational productStudy of the clinical trial procedure under the U.S. law revealed that there is a continuous supervision over clinical trials and controls are provided on the treatment use of an investigational product.the study of the provisions of the Drugs and Cosmetics Act and the rules framed under it revealed that the law in this regard is comprehensive to protect the consumer provided it is sufficiently supported by adequately equipped enforcement machinery.

Determinants of Consumer Purchase Decisions of Health Insurance in Kerala

This research work was to study the level of awareness of consumers about health insurance concept and market, consumer perceptions about health insurance providers, schemes and various factors that influence buying decision of health insurance. There is need to bring entire age group – high risk and low risk under health insurance cover. Widening the cover of health insurance calls for indepth understanding of consumer thinking and extensive marketing efforts based on that. Hence the study of consumer perceptions and the impact of different contributing factors on consumer purchase decision assume significance to the marketer. Understanding the consumer thinking on health insurance will also be of relevance to governmental/non governmental agencies, as affordable health care to all is a policy objective of the government and new schemes are being launched in this area.

Model Development and Validation for Studying Consumer Preferences of Car Owners

Globalization and liberalization, with the entry of many prominent foreign manufacturers, changed the automobile scenario in India, since early 1990‟s. Manufacturers such as Ford, General Motors, Honda, Toyota, Suzuki, Hyundai, Renault, Mitsubishi, Benz, BMW, Volkswagen and Nissan set up their manufacturing units in India in joint venture with their Indian counterpart companies, by making use of the Foreign Direct Investment policy of the Government of India, These manufacturers started capturing the hearts of Indian car customers with their choice of technological and innovative product features, with quality and reliability. With the multiplicity of choices available to the Indian passenger car buyers, it drastically changed the way the car purchase scenario in India and particularly in the State of Kerala. This transformed the automobile scene from a sellers‟ market to buyers‟ market. Car customers started developing their own personal preferences and purchasing patterns, which were hitherto unknown in the Indian automobile segment. The main purpose of this paper is to come up with the identification of possible parameters and a framework development, that influence the consumer purchase behaviour patterns of passenger car owners in the State of Kerala, so that further research could be done, based on the framework and the identified parameters

Conceptualisation Of Model For Studying Consumer Purchase Behaviour Of Passenger Cars

Automobile Industry in India is influenced by the presence of national and multi-national manufacturers. The presence of many manufacturers and brands in the state provides many choices to the customer. The current market for car manufacturers has been transformed from a monopoly of one or two manufacturers in the seventies to oligopoly of many manufacturers in the current marketing scenario. The main objective of the research paper is to explore and conceptualize various parameters and develop a model, which influence the purchase patterns of passenger cars in the State of Kerala. Thus, the main purpose of this paper is to come up with a model, which shall facilitate further study on the consumer purchase behaviour patterns of passenger car owners in the State of Kerala, India. The author intends to undertake further quantitative analysis to verify and validate the model so developed. The main methods used for this paper are secondary research on available material, depth interview of car dealers, car financing agencies and car owners in the city of Cochin, in Kerala State in India. The depth interviews were conducted with the use of prepared questionnaire for car dealers, car customers and car financing agencies. The findings resulted in the identification of the parameters that influence the consumer purchase behaviour of passenger cars and the formulation of the model, which will be the basis for the further research of the author. The paper will be of tremendous value to the existing and new car manufacturers both indigenous and foreign, to formalize and strategies their policies towards an effective marketing strategy, so as to market their models in the State, which is known for its high literacy, consumerism and higher educational penetration
