P methods for choice-based conjoint analysis provide a means to adapt choice-based questions at the individual-respondent level and provide an alternative means to estimate partworths when there are relatively few questions per respondent, as in a Web-based questionnaire. However, these methods are deterministic and are susceptible to the propagation of(More)
Agent-based modelers in the field of marketing research have paid little attention to validation issues. This paper provides a definition of validation relevant for this community of modelers. On the basis of a history-friendly model for simulation calibration [Malerba, F., Nelson, R., Orsenigo, L., and Winter, S. (1999). ‘History-friendly’ models of(More)
I n recent years, agent-based modeling has gained popularity in many scientific areas as a modeling tool capable of capturing the dynamics that arise from the interactions between individuals (e.g, Gilbert and Troitzsch, 2005). The perspective of this method, rooted in complexity theory, is that phenomena at the macro—or aggregated—level can be understood(More)
Purpose – The purpose of this research is to examine gender differences in information search procedures and selection criteria relative to purchase situation and social and financial risk aversion. Design/methodology/approach – An online questionnaire was completed by 497 males and 877 females in the USA. A total of 88 percent of the respondents stated(More)
Management. We wish to thank Kevin Stanik and Andrew Rutkiewitz for their computer support as well as Tom Atkin and Larry Lockshin with their wine industry expertise.

There has been a great deal written about the diffusion of discontinuous technical innovations, but very little about diffusion of discontinuous innovations in other areas, such as packaging. Also, little research explores differences in diffusion rates of low-technological discontinuous innovations in different countries or cultures. This project studies(More)
Validation issues have received little attention by agent-based modelers in marketing research. In this paper we provide a definition of validation relevant for this community of modelers. Using the foundation of a history-friendly model for simulation calibration (Malerba, et al., 1999), we demonstrate how conjoint analyses can be used to instantiate and(More)
