Comment on “Revealing Differences in Willingness to Pay Due to the Dimensionality of Stated Choice Designs: An Initial Assessment”

There are very few studies that quantify the interactions and tradeoffs between statistical and cognitive efficiency in designing stated-choice studies. While a conceptual framework for evaluating cognitive strategies would be desirable, Hensher adopts a strictly empirical approach in this experiment. The success of the study must be evaluated in light of his aggregating attributes rather than controlling the number of attributes, asymmetry in the narrow-range and wide-range attributes, and lack of orthogonality between the number of attributes and number of alternatives. Nevertheless, Hensher challenges uncritical acceptance of any given set of design features and correctly insists that we confirm our experience with rigorous, quantitative experiments.     

Do alliances promote knowledge flows?

We explore the role of interfirm alliances as a mechanism for sharing technological knowledge. We argue that knowledge flows between alliance partners will be greater than flows between pairs of nonallied firms, and less than flows between units within single firms. Using patent citations as a proxy for knowledge flows, we find results that are consistent with these expectations. We then explore how firm characteristics affect knowledge flows within alliances and find positive effects due to technological, geographic, and business similarities between partners. We use alliance data from MERIT, patent data from the USPTO, and firm data from Compustat.     

Social identity as a useful perspective for self‐concept–based consumer research

Psychology's study of the self‐concept has generated numerous paradigms with different underlying assumptions. In this article it is argued that these assumptions must be considered before a self‐concept paradigm can be meaningfully applied to consumer research. The major premise in this article is that the recent work on social identity is a particularly meaningful paradigm to adopt for consumer research that implicates the self. This argument is developed with a conceptual discussion of major self‐concept issues, an overview of basic self‐concept paradigms in psychology, and a synthesis of possible factors that may be considered in future theories of social‐identity–based consumption decision making. © 2002 Wiley Periodicals, Inc.     

Factors affecting consumer acceptance of chilled ready meals on the island of Ireland

The chilled ready meal market on the island of Ireland is relatively young but is growing rapidly. This paper focused on a consumer questionnaire (n = 702), designed to examine consumer attitudes to and consumption of chilled ready meals, in both the north and south of Ireland. This formed part of a larger study, with the questionnaire findings contributing to an in‐depth sensory study on a selected range of chilled ready meals. For a significant number of Irish consumers, consumption of these products is higher than on the UK mainland. For others, the products are purchased as a convenient alternative or a weekly treat. Respondents in urban locations were significantly more likely to consume chilled ready meals, as were men and younger, single respondents. Irish consumers are becoming more accustomed to ethnic cuisine although traditional meals remain popular. There is a clear need for developers to continue to enhance the sensory quality of these products, particularly as the primary barrier to consumption was a preference for home cooked food. However, they must also strive to maintain consumer interest in the sector, fulfil the desire for convenience and satisfy a more discerning palate.

Operations change interactions in a service environment: Attitudes,behaviors, and profitability

An attitudinal and behavioral change program was developed and implemented in a service operations function. Changes were (1) stabilizing operations management (reducing turnover) and (2) improving attitudes and behaviors of employees with strong union affiliations in a common carrier trucking terminal when compared to similar employees in a control terminal undergoing no planned change. Management turnover was reduced. Other results from the eighteen-month longitudinal study indicated that employee attitudes in both groups remained negative toward work, management, and the company throughout the study period. Behaviors relating to attitudes — particularly turnover, absenteeism, and accident rates—improved at the experimental terminal, even though expressed attitudes remained negative. Operating efficiencies and profitability improved at the experimental terminal. It was found that these employees, pick-up and delivery drivers, retain positive attitudes toward customers and customers the same toward them, in spite of the drivers' negative attitudes toward the company. The operative service employee appeared to discriminate between attitudes toward the company and the customer; the drivers' negative attiudes toward most everything (except the customer) not affecting the customer's perceptions of the driver or the company.     

BRITISH POTATO STABILISATION POLICY IN A EUROPEAN CONTEXT

This paper presents a simulation model, based on a stochastic spatial equilibrium framework, for the GB potato market, allowing for trade with the Continent and the operation of domestic stabilisation policy. The model is used to explain the operation of the two policy instruments — support buying and area control — and to evaluate policy options and consequences. The notion of a cost-effective support buying programme is introduced and it is found that current policy is in the region of cost-effectiveness. Quota area, subject to the constraint that downside price risk is avoided, is found to lead to a trade-off between the consumer interest and the financial cost of policy. This trade-off is examined in a conventional welfare analysis and in probability terms. Subject to certain caveats, it is concluded that current policy tends to provided price stabilisation rather than price enhancement for producers.
