Two notions of social capital J. Math. Sociol. (IF 1.0) Pub Date : 2021-12-07 Matteo Alpino, Halvor Mehlum
ABSTRACT We propose a model that reconciles two aspects of social capital: social capital as reciprocal sharing of favors within a selected group vs. social capital as trust that lubricates transactions in societies. The core assumption is that individuals have productive potentials, e.g., innovations, that can not be put at use autonomously. However, individuals can associate in a club to match productive

Sociophysics of income distributions modeled by deformed fermi-dirac distributions J. Math. Sociol. (IF 1.0) Pub Date : 2021-10-05 Emre Dil, Elif Dil
ABSTRACT In order to model the income data, the physical distributions of Fermi-Dirac and Bose-Einstein families have already been proposed in the literature. In this study, we generalize Fermi-Dirac distribution by using a q,p-deformed version of Fermi-Dirac distribution which provides the advantage of working with flexible free q, p deformation parameters as the regression parameters for modeling

A model of income evaluation: income comparison on subjective reference income distribution J. Math. Sociol. (IF 1.0) Pub Date : 2021-10-01 Atsushi Ishida
ABSTRACT People’s evaluation of the relative position of their income is not as accurate as the relative income hypothesis assumes. It is observed from empirical survey data that income evaluation is concentrated in the middle. We develop a model that assumes income comparison on a subjective income reference distribution to explain the centralization phenomenon of income evaluation. We conduct theoretical

Hiding opinions by minimizing disclosed information: an obfuscation-based opinion dynamics model J. Math. Sociol. (IF 1.0) Pub Date : 2021-08-17 Tanzhe Tang, Amineh Ghorbani, Caspar G. Chorus
ABSTRACT In the field of opinion dynamics, the hiding of opinions is routinely modeled as staying silent. However, staying silent is not always feasible. In situations where opinions are indirectly expressed by one’s observable actions, people may however try to hide their opinions via a more complex and intelligent strategy called obfuscation, which minimizes the information disclosed to others. This

Friend or Foe: A Review and Synthesis of Computational Models of the Identity Labeling Problem J. Math. Sociol. (IF 1.0) Pub Date : 2021-06-01 Kenneth Joseph, Jonathan Howard Morgan
ABSTRACT We introduce the identity labeling problem – given an individual in a social situation, can we predict what identity(ies) they will be labeled with by someone else? This problem remains a theoretical gap and methodological challenge, evidenced by the fact that models of social-cognition often sidestep the issue by treating identities as already known. We build on insights from existing models

A measure of centrality based on a reciprocally perturbed Markov chainfor asymmetric relations J. Math. Sociol. (IF 1.0) Pub Date : 2021-02-27 Neng-Pin Lu
ABSTRACT In digraphs representing asymmetric relations, the measured scores of previous spectral rankings are usually dominated by nodes in the largest strongly connected component. In our previous work, we proposed hierarchical alpha centrality to give higher scores for more reachable nodes not in the largest strongly connected component. However, without careful consideration of damping parameters

Eigenvector centralization as a measure of structural bias in information aggregation J. Math. Sociol. (IF 1.0) Pub Date : 2021-02-25 Elisa Jayne Bienenstock, Phillip Bonacich
Abstract The principal eigenvector of the adjacency matrix is widely used to complement degree, betweenness and closeness measures of network centrality. Employing eigenvector centrality as an individual level metric underutilizes this measure. Here we demonstrate how eigenvector centralization, used as a network-level metric, models the potential, or limitation, for the diffusion of novel information

Incentive structures: quality competition and the production of fine Californian wines J. Math. Sociol. (IF 1.0) Pub Date : 2020-12-20 Malte Doehne
ABSTRACT When and for whom does it pay to make high-quality products? In this paper, I address this question through the lens of Harrison White’s socioeconomic models of production. The socioeconomic models relate economist incentives of cost-efficiency to sociological insights into the construction of quality on markets. Differences in firm size and quality sustain distinct market niches whose appeal

Formal models of opinion formation and their application to real data: evidence from online social networks J. Math. Sociol. (IF 1.0) Pub Date : 2020-10-29 Ivan V. Kozitsin
ABSTRACT In this paper, we analyze data on the opinion dynamics of 1,660,927 users of an online social network using formal models of opinion formation. We have observed that moderate users have a tendency to follow the average opinion of their online friends, which we interpret as a presence of bounded confidence. Further, we have discovered that the probability of moving toward the average opinion

An agent-based model of deliberative democracy and polarization J. Math. Sociol. (IF 1.0) Pub Date : 2020-10-25 Bokwon Lee, Yohan Kim, K.M Lee, Jae-Suk Yang
ABSTRACT In this paper, we examined the effect of deliberative democracy on the polarization of opinion. Through three case analyses, we find that deliberative democracy has two major components – provision of information and group discussion. Polarization of opinion can be explained by several theories: social identity theory, social comparison, and confirmation bias. We constructed a deliberative

The power of voting and corruption cycles J. Math. Sociol. (IF 1.0) Pub Date : 2020-09-16 E. Accinelli, Filipe Martins, Alberto A. Pinto, Atefeh Afsar, Bruno M. P. M. Oliveira
ABSTRACT We introduce an evolutionary dynamical model for corruption in a democratic state describing the interactions between citizens, government and officials, where the voting power of the citizens is the main mechanism to control corruption. Three main scenarios for the evolution of corruption emerge depending on the efficiency of the institutions and the social, political, and economic characteristics

Positive algorithmic bias cannot stop fragmentation in homophilic networks J. Math. Sociol. (IF 1.0) Pub Date : 2020-09-13 Chris Blex, Taha Yasseri
ABSTRACT Fragmentation, echo chambers, and their amelioration in social networks have been a growing concern in the academic and non-academic world. This paper shows how, under the assumption of homophily, echo chambers and fragmentation are system-immanent phenomena of highly flexible social networks, even under ideal conditions for heterogeneity. We achieve this by finding an analytical, network-based

Convex combinations of centrality measures J. Math. Sociol. (IF 1.0) Pub Date : 2020-07-27 Ying Ying Keng, Kiam Heong Kwa, Christopher McClain
ABSTRACT Despite a plethora of centrality measures were proposed, there is no consensus on what centrality is exactly due to the shortcomings each measure has. In this manuscript, we propose to combine centrality measures pertinent to a network by forming their convex combinations. We found that some combinations, induced by regular points, split the nodes into the largest number of classes by their

A dynamic process reference model for sparse networks with reciprocity J. Math. Sociol. (IF 1.0) Pub Date : 2020-07-25 Carter T. Butts
ABSTRACT Many social and other networks exhibit stable size scaling relationships, such that features such as mean degree or reciprocation rates change slowly or are approximately constant as the number of vertices increases. Statistical network models built on top of simple Bernoulli baseline (or reference) measures often behave unrealistically in this respect, leading to the development of sparse

Exploring ideological signals from cosponsorship J. Math. Sociol. (IF 1.0) Pub Date : 2020-07-22 Carol Ann Downes, Philip D. Waggoner
ABSTRACT While cosponsorship is a useful tool for cosponsors, what is its impact on the bill? Adapting the mathematical concept of directed transportation networks for the American Congressional context, we suggest cosponsorship’s impact on a bill comes in the form of an ideological signal. We offer a model of policymaking where ideological “weight” is added to bills each time legislators sign on as

Spontaneous cooperation for public goods J. Math. Sociol. (IF 1.0) Pub Date : 2020-04-24 Jeroen Bruggeman, Rudolf Sprik, Rick Quax
Cooperation for public goods poses a dilemma, where individuals are tempted to free ride on others' contributions. Classic solutions involve monitoring, reputation maintenance and costly incentives, but there are important collective actions based on simple and cheap cues only, for example unplanned protests and revolts. This can be explained by an Ising model with the assumption that individuals in
