Useful heuristics

Decision-making is one of the core tasks in project management. Traditionally, optimization methods have been developed to support managers in finding the best solutions. Alternatively, decisions can be based on simple rules of thumb, or heuristics. Even though simple heuristics only require little in the way of time and information, they have been shown to outperform optimization...

What moderates the too-much-choice effect?

Core theories in economics, psychology, and marketing suggest that decision makers benefit from having more choice. In contrast, according to the too-much-choice effect, having too many options to choose from may ultimately decrease the motivation to choose and the satisfaction with the chosen option. To reconcile these two positions, we tested whether there are specific conditions...

Cognitive models of choice: comparing decision field theory to the proportional difference model

People often face preferential decisions under risk. To further our understanding of the cognitive processes underlying these preferential choices, two prominent cognitive models, decision field theory (DFT; Busemeyer & Townsend, 1993) and the proportional difference model (PD; González-Vallejo, 2002), were rigorously tested against each other. In two consecutive experiments, the...

Predicting children's meal preferences: how much do parents know?

We investigate how accurate parents are at predicting their children's meal preferences and what cues best describe parents’ predictions. In Study 1, 30 parents predicted their children's school lunch choices from actual school menus. Parents’ prediction accuracy matched the stability of children's meal choices (assessed in a 4-month retest), implying that accuracy was...

Incorporating Latent Variables into Discrete Choice Models - A Simultaneous Estimation Approach Using SEM Software

Integrated choice and latent variable (ICLV) models represent a promising new class of models which merge classic choice models with the structural equation approach (SEM) for latent variables. Despite their conceptual appeal, applications of ICLV models in marketing remain rare. We extend previous ICLV applications by first estimating a multinomial choice model and, second, by...
