Opinion dynamics, stubbornness and mean-field games

2014

This paper studies opinion dynamics and stubbornness using mean-field game theory. Assuming an initial exponential density function and affine control policies we analyze under what conditions the Fokker-Planck equation returns an exponential density function over the horizon. Consensus and clusters formation are also studied.

Best Friends Forever? Modeling the Mechanisms of Friendship Network Formation

2020

The formation of friendships and alliances is a ubiquitous feature of human life, and likely a crucial component of the cooperative hunting and child-rearing practices that helped our early hominin ancestors survive. Research on contemporary human beings typically finds that strong-tie social networks are fairly small, and reveals a high degree of physical (e.g., age) and social-structural (e.g., educational attainment) homophily. Yet, existing work all too often underestimates, or even ignores, the importance of abstract, symbolic homophily (such as shared identities or worldviews) as a driver of friendship formation. Here we employ agent-based modeling to identify the optimal variable wei…

Stretching the value-satisfaction-loyalty chain by adding value dimensions and cognitive and affective satisfactions

2016

Purpose– Consensus on how value dimensions are drivers of overall perceived value is a widespread reality in consumer behaviour literature. But scanty research has been done on which of these value dimensions best predict customer loyalty. The purpose of this paper is to propose a causal model that examines how PERVAL dimensions of value affect customers’ loyalty, through both cognitive and affective satisfaction.Design/methodology/approach– The model is tested on a sample of 820 Spanish retail customers and the findings suggest that product quality and value for money (cognitive) impact customer loyalty through emotional and social value (affective), with significant direct and indirect ef…

Analyzing heterogeneity on the value, satisfaction, word-of-mouth relationship in retailing

2017

Purpose The literature recognizes the need to study differences in consumer behavior in highly competitive and dynamic markets. In this paper, the authors look at how the heterogeneous evaluation of retailing influences customer satisfaction and loyalty. The purpose of this paper is to analyze unobserved heterogeneity on customer value dimensions perceptions in retail establishments, and their potential effects on positive forms of behavioral outcomes considering customer satisfaction as a mediating variable. Design/methodology/approach On a sample of 820 retail customers, the authors apply a finite mixture structural equation modeling that analyzes unobserved heterogeneity simultaneously.…

Levels of cognitive congruence between managers and team members’ perceptions of cooperation at work

2019

Much of the research on the psychological dynamics of performance teams suffers from the following limitations: consideration of only one theoretical framework and analysis of just one perspective (e.g., manager&ndash

Persistent joblessness and fertility intentions

2019

Background: The vast majority of demographic studies have approached and operationalised the notion of economic uncertainty using snapshot indicators. Hence, the complexity and diversity of individuals' employment careers were largely hidden. We posit that the persistence of joblessness - that is, repeated and close spells of joblessness - represents a crucial marker of economic uncertainty in the realm of fertility (intention) research. Objective: We aim to explore the association between persistent joblessness of both members of the couple and women's fertility intentions among those who entered employment at least once in the last five years. Methods: We develop an index of persistent jo…

An operatorial approach to stock markets

2009

We propose and discuss some toy models of stock markets using the same operatorial approach adopted in quantum mechanics. Our models are suggested by the discrete nature of the number of shares and of the cash which are exchanged in a real market, and by the existence of conserved quantities, like the total number of shares or some linear combination of cash and shares. The same framework as the one used in the description of a gas of interacting bosons is adopted.

Adoption of ubiquitous crm for operational sustainability of the firms: Moderating role of technology turbulence

2021

Ubiquitous CRM (UCRM) enhances customer relationship management. It can sense customer needs and demands, to which firms can respond quickly. Therefore, UCRM helps to improve a firm’s agility. There is a growing interest among researchers and practitioners to understand how the adoption of UCRM impacts the sustainability of firms’ operations, but not many studies have investigated this issue. In this context, the aim of this study is to examine how firms’ absorptive capacity and dynamic capability could impact the adoption of UCRM to influence the operational sustainability of the firms and their performance. The study also investigates the moderating role of technology turbulence on the re…

Data from: Growing up with feces: benefits of allo-coprophagy in families of the European earwig

2016

An important issue in the evolution of group living is the risk of pathogen and predator exposure entailed by the inherent accumulation of feces within a nesting site. While many group living species limit this risk by cleaning the nest, others do not, raising questions about the benefits of maintaining feces in the nest and their importance in social evolution. Here, we investigated whether one of these benefits could be mediated by coprophagy in families of the European earwig, Forficula auricularia. In this insect species, mothers and mobile juveniles (nymphs) line their nests with feces and consume them. In a first experiment, we tested whether access to feces produced by either nymphs …
