Abstract. This article provides a theoretical model for systematic analysis of interaction of consumer preferences with preferences of producers and of government. The central question of the study is whose preferences are rendered effective and to what extent. A theoretical framework for analysis of diverse economic systems is used to derive preference and opportunity functions of decision‐making units on consumption, production, and government sides. This model is broadened by introduction of elements of a theory of change based on the postulates of necessary and sufficient conditions. Galbraith's model is placed analytically between the two extreme ideal types and subjected to a critical analysis.

AbstractGrowing concern about the degradation of the environment and public health has called into question the use of conventional household batteries that are consumed and then typically discarded. Because most conventional batteries are not recycled, they end up in landfills where they decompose, potentially leaching harmful chemicals into the surrounding soil. Bio‐based batteries, which are made from agricultural by‐products, have been designed to help meet the need for household batteries while using sustainable, safe technology. This research examines the links between consumer willingness‐to‐pay (WTP) for bio‐based batteries and consumer characteristics and preferences for certain product attributes and environmentally‐friendly practices. We designed a nationwide survey and analyzed the survey data using the dichotomous‐choice contingent valuation method. The results show an increase in the estimated WTP in the Midwest and South in response to an information treatment about bio‐based batteries. Overall, U.S. consumers concerned about green production and recycling practices are willing to pay a premium for bio‐based batteries. Our results provide essential information for quantitatively assessing the potential market impact of bio‐based batteries, for developing effective management and marketing strategies to reach various consumer groups, and for efficiently establishing sustainable policies and regulations.

Abstract
When consumers have preference costs, two opposing effects need to be assessed to analyse the incentives of firms to set collusive prices. On the one hand, preference costs make a deviation from collusion less attractive, as the deviating firm must offer a large enough discount to cover the preference costs. On the other hand, preference costs lock in consumers and make punishment from rivals less effective. When preference costs are low, the latter of the two effects dominates and collusion is more challenging to sustain than in a situation with no preference costs. With high enough preference costs, collusion is a (weakly) dominant strategy. These results do not eventuate in a model with switching costs.

In Korea, fishery managers, eco-labeled program operators, and the government need detailed information regarding individual-level preferences for eco-labeled seafood. This study aims to identify the determinants of consumer preference for such seafood. Specifically, an ordered probit model is estimated by using micro-survey data obtained from interviews of 2773 randomly selected Korean households. Overall, the estimation results reveal that the chosen model is appropriate to analyze consumer preference for eco-labeled seafood. The coefficients of consumption frequency, the importance of price, the confirmation of origin, residential area, and household income are statistically meaningful. If consumers consider price an important factor, their consumption of eco-labeled seafood may decrease. Moreover, consumers with interest in the origin of seafood are more likely to accept eco-labeled seafood. To increase the consumption of eco-labeled seafood, it is recommended to develop products designed specifically for segmented markets and promote functional features. The findings can provide a valuable guideline to marketing managers and policy makers for designing effective strategies regarding eco-labeled seafood.

Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Marketing Intelligence ; Advertising is a paid form of presentation of goods, services, ideas by an identified sponsor. Companies spend huge amount of money on advertising and try to focus on solving consumer needs and address their preference. To run a good and strategic campaign, Marketing departments must know their costumers' preferences. This is one of the lacks in the segment of Ostomy Care, which is the field of medicine that takes care of chronic patients with a stoma. From one day to another, after a surgery, they need to live with a stoma to be able to address physiologic needs. Since the beginning of this therapeutic care patients have listened to their nurses and used the products they recommend. However, once this product is 100% reimbursed, since 2017, by the government in Portugal, patients have the change of choosing it no matter how much it costs. It is estimated that those patients have chosen their own products. This research intended to study if they really choose their products and what are their criteria when taking the decision of using it. With these answers, Marketing department could develop better campaigns, focused on what they really care. As results, it was found that yes, most Portuguese ostomized people do choose their products and the most valued criteria are stick well on the skin, have a secure fit and being comfortable. In this sense, marketing departments of OC companies should focus on promoting it.
