Network Contagion in Financial Labor Markets: Predicting Turnover in Hong Kong
Employee turnover is a critical challenge in financial markets, yet little is known about the role of professional networks in shaping career moves. Using the Hong Kong Securities and Futures Commission (SFC) public register (2007-2024), we construct temporal networks of 121,883 professionals and 4,979 firms to analyze and predict employee departures. We introduce a graph-based feature propagation framework that captures peer influence and organizational stability. Our analysis shows a contagio…

But there is no certainty that madness was content to sit locked up in its immutable identity, waiting for psychiatry to perfect its art, before it emerged blinking from the shadows into the blinding light of truth. Nor is it clear that confinement was above all, or even implicitly, a series of measures put in place to deal with madness. It is not even certain that in this repetition of the ancient gesture of segregation at the threshold of the classical age, the modern world was aiming to wipe out all those who, either as a species apart or a spontaneous mutation, appeared as 'asocial'. The fact that the internees of the eighteenth century bear a resemblance to our modern vision of the asocial is undeniable, but it is above all a question of results, as the character of the marginal was produced by the gesture of segregation itself. For the day came when this man, banished in the same exile all over Europe in the mid-seventeenth century, suddenly became an outsider, expelled by a society to whose norms he could not be seen to conform; and for our own intellectual comfort, he then became a candidate for prisons, asylums and punishment. In reality, this character is merely the result of superimposed grids of exclusion.
The gesture that proscribed was as abrupt as the one that had isolated the lepers, and in both cases, the meaning of the gesture should not be mistaken for its effect. Lepers were not excluded to prevent contagion, any more than in 1657, 1 per cent of the population of Paris was confined merely to deliver the city from the 'asocial'. The gesture had a different dimension: it did not isolate strangers who had previously remained invisible, who until then had been ignored by force of habit. It altered the familiar cityscape by giving them new faces, strange, bizarre silhouettes that nobody recognised. Strangers were found in places where their presence had never previously been suspected: the process punctured the fabric of society, and undid the familiar. Through this gesture, something inside man was placed outside of himself, and pushed over the edge of our horizon. It is the gesture of confinement, in short, which created alienation.

Once the distinctions had been made, and the first punishments applied, the venereal were accepted into the hospital. And they were crammed inside. In 1781, 138 men occupied 60 beds in the Saint-Eustache quarter of Bicêtre, and in the Miséricorde in the Salpêtrière there were 125 beds for 224 women. Patients in the terminal stages of the disease were simply left to die. 'Grand Remedies' were applied to the others: never more, and rarely less than six weeks of care, starting of course with blood-letting and purging, then a week of baths for two hours per day, then purging again, followed by a full and complete confession to bring this first part of the treatment to a close. Rubbing with mercury could then begin, with all its efficacy. Each course of treatment lasted one month, and was followed by two more purges and one final bleeding to chase out the remaining morbific humours. Fifteen days of convalescence were then granted. After he had definitively made his peace with God, the patient was declared cured and sent away.
This 'therapeutic' demonstrates a rich tapestry of fantasy, and above all a profound complicity between medicine and morality, which give their full meaning to these purification practices. For the classical age, venereal disease was less a sickness than an impurity to which physical symptoms are correlated. Accordingly, medical perception is ruled by ethical perception, and on occasion even effaced by it. The body must be treated to remove the contagion, but the flesh must be punished, for it is the flesh that attaches us to sin. Mere corporal punishment was not enough: the flesh was to be pummelled and bruised, and leaving painful traces was not to be feared, as good health, all too frequently, transformed the human body into another opportunity for sinful conduct. The sickness was to be treated, but the good health that could lead to temptation was to be destroyed.

Emergent Directedness in Social Contagion
An enduring challenge in contagion theory is that the pathways contagions follow through social networks exhibit emergent complexities that are difficult to predict using network structure. Here, we address this challenge by developing a causal modeling framework that (i) simulates the possible network pathways that emerge as contagions spread and (ii) identifies which edges and nodes are most impactful on diffusion across these possible pathways. This yields a surprising discovery. If people r…

Explosive adoption of corrupt behaviors in social systems with higher-order interactions
Human behaviors in social systems are often shaped by group pressure and collective norms, especially since the rise of social media platforms. However, in the context of adopting misbehaviors, most existing contagion models rely on pairwise interactions and thus fail to capture group-level dynamics. To fill this gap, we introduce a higher-order extension of the Honesty-Corruption-Ostracism (HCO) model to study the emergence of systemic corruption in populations where individuals interact throu…

Weak Identification in Peer Effects Estimation
It is commonly accepted that some phenomena are social: for example, individuals' smoking habits often correlate with those of their peers. Such correlations can have a variety of explanations, such as direct contagion or shared socioeconomic circumstances. The network linear-in-means model is a workhorse statistical model which incorporates these peer effects by including average neighborhood characteristics as regressors. Although the model's parameters are identifiable under mild structural …

Predictive Control Strategies for Sustaining Innovation Adoption on Multilayer Social Networks
This paper studies an optimal control problem for an adoption-opinion model that couples innovation adoption with opinion formation on a multilayer network. Adoption spreads through social contagion and perceived benefits, while opinions evolve via social interactions and feedback from adoption levels. Individuals may abandon adoption due to dissatisfaction or external constraints, potentially hindering diffusion. We analyze system equilibria and their stability, identifying conditions under wh…

Community-level Contagion among Diverse Financial Assets
As global financial markets become increasingly interconnected, financial contagion has developed into a major influencer of asset price dynamics. Motivated by this context, our study explores financial contagion both within and between asset communities. We contribute to the literature by examining the contagion phenomenon at the community level rather than among individual assets. Our experiments rely on high-frequency data comprising cryptocurrencies, stocks and US ETFs over the 4-year perio…

Optimal Control of an SIR Model with Noncompliance as a Social Contagion
We propose and study a compartmental model for epidemiology with human behavioral effects. Specifically, our model incorporates governmental prevention measures aimed at lowering the disease infection rate, but we split the population into those who comply with the measures and those who do not comply and therefore do not receive the reduction in infectivity. We then allow the attitude of noncompliance to spread as a social contagion parallel to the disease. We derive the reproductive ratio for…

Group Survival Probability under Contagion in Microlending
In this paper we apply a probabilistic approach to analyze the impact of contagious default among investment group members. A general formula is given to compute the group survival probability with the presence of contagion effect. Special cases of this probability model are examined. In particular, we show that if the investment group is homogeneous, defined in the paper, then including more members into the group will eventually lead to default with probability 1, contrasting with the non-con…

Burning games on strong path products
Burning and cooling are diffusion processes on graphs in which burned (or cooled) vertices spread to their neighbors with a new source picked at discrete time steps. In burning, the one tries to burn the graph as fast as possible, while in cooling one wants to delay cooling as long as possible. We consider $d$-fold strong products of paths, which generalize king graphs. The propagation of these graphs is radial, and models local spread of contagion in an arbitrary number of dimensions. We red…

Do triangles matter? Replicating hypergraph disease dynamics with lower-order interactions
Disease spreading models such as the ubiquitous SIS compartmental model and its numerous variants are widely used to understand and predict the behaviour of a given epidemic or information diffusion process. A common approach to imbue more realism to the spreading process is to constrain simulations to a network structure, where connected nodes update their disease state based on pairwise interactions along the edges of their local neighbourhood. Simplicial contagion models (SCM) extend this to…

Symmetry breaking in collective decision-making through higher-order interactions
Collective decision-making is a widespread phenomenon in both biological and artificial systems, where individuals reach a consensus through social interactions. While traditional models of opinion dynamics and contagion focus on pairwise interactions, recent research emphasizes the importance of including higher-order group interactions and autonomous behavior to better reflect real-world complexity. In this work, we introduce a collective decision-making model inspired by social insects. In o…

Generative Intelligence Systems in the Flow of Group Emotions
Emotional cues frequently arise and shape group dynamics in interactive settings where multiple humans and artificial agents communicate through shared digital channels. While artificial agents lack intrinsic emotional states, they can simulate affective behavior using synthetic modalities such as text or speech. This work introduces a model for orchestrating emotion contagion, enabling agents to detect emotional signals, infer group mood patterns, and generate targeted emotional responses. The…

Efficient Gillespie algorithms for spreading phenomena in large and heterogeneous higher-order networks
Higher-order dynamics refer to mechanisms where collective mutual or synchronous interactions differ fundamentally from their pairwise counterparts through the concept of many-body interactions. Phenomena absent in pairwise models, such as catastrophic activation, hysteresis, and hybrid transitions, emerge naturally in higher-order interacting systems. Thus, the simulation of contagion dynamics on higher-order structures is algorithmically and computationally challenging due to the complexity o…
