Preferences stability: A measure of preferences changes over time

Public Healthcare: Citizen’s Preferences in Spain

“…Once the preferences have been established, the local and the global preference stability measures can be computed by Definitions 2 and 3 from [ 8 ], respectively. Figure A1 provides an overview of the local decision stability measures obtained for the entire society.…”

“…All these computations require proper methodologies. Given that in this contribution the preferences are expressed like complete pre-orders and the model from [ 8 ] has been assumed, it is coherent to adopt the methodology presented in [ 14 , 15 ]. These works approach the consensus or dissensus measurement for a collection of complete pre-orders based on the Mahalanobis distance and they also present the development of a social consensus solution as an appropriate representative from an optimization problem.…”

“…As far as we know, there are few studies that have investigated how to measure the stability of temporal preferences (see in [ 11 , 12 , 13 ]). In this contribution, the methodology proposed by de Andrés Calle, Cascón and González-Arteaga in [ 8 ] is used for measuring changes on preferences over time. This approach is particularly useful in measuring how much preferences change over time when preferences are considered as complete pre-orders.…”

“…Taking into account these starting points, this paper focuses on analyzing the preferences of Spaniards on their healthcare system over time under the assumption that citizens’ preferences are represented by complete pre-orders. Therefore, the methodological approach taken in this study is the methodology proposed by Andrés Calle, Cascón, and González-Arteaga in [ 8 ] that it was especially designed for such aim. Data for this study were collected from Spanish Health Barometer survey and they were searched from 1995 until 2018.…”

How to elicit and cease herding behaviour? On the effectiveness of a warning message as a debiasing decision support system

“…In the present study, we use a randomised peer information intervention to evaluate whether herding behaviour influences decisionmaking in the context of financial decisions, in particular buying disability insurance and retirement planning. As a basis for this study, we design a DSS that intends to support the decision-making of individuals in these specific contexts, noting the growing importance of DSSs for financial decisions [25,39]. We also examine how convincing the information on the crowd's decision needs to be before people start to demonstrating herding behaviour.…”
