Spring finally here in Toronto. Saw my first YA in shorts. Yet only 10 
degrees out (that's 50 for the Americans).

Methods for quantifying effects of social unrest using credit card transaction data

    Societal unrest and similar events are important for societies, but it 
is often difficult to quantify their effects on individuals, hindering a 
timely and effective policy-making in emergencies and in particular 
localized social shocks such as protests. Traditionally, effects are 
assessed through economic indicators or surveys with relatively low 
temporal and spatial resolutions. In this work, we compute two behavioral 
indexes, based on the use of credit card transaction data, for measuring 
the economic effects of a series of protests on consumer actions and 
personal consumption. Using data from a metropolitan area in an OECD 
country, we show that protests affect consumers˙˙ shopping frequency and 
spending, but in noticeably different ways. The effects show strong 
temporal and spatial patterns, vary between neighborhoods and customers of 
different socio-demographical characteristics as well as between merchants 
of different categories, and suggest interesting subtleties in purchase 
behavior such as displaced or delayed shopping activities. Our method can 
generally serve for the real-time monitoring of the effects of major 
social shocks or events on urban economy and consumer sentiment, providing 
high-resolution and cost-effective measurement tools to complement 
traditional economic indicators.

Population Structure Promotes the Evolution of Intuitive Cooperation and Inhibits Deliberation

Spatial structure is one of the most studied mechanisms in evolutionary 
game theory. Here, we explore the consequences of spatial structure for a 
question which has received considerable empirical and theoretical 
attention in recent years, but has not yet been studied from a network 
perspective: whether cooperation relies on intuitive predispositions or 
deliberative self-control. We examine this question using a model which 
integrates the ˙˙dual-process˙˙ framework from cognitive science with 
evolutionary game theory, and considers the evolution of agents who are 
embedded within a social network and only interact with their neighbors. 
In line with past work in well-mixed populations, we find that selection 
favors either the intuitive defector strategy which never deliberates, or 
the dual-process cooperator strategy which intuitively cooperates but uses 
deliberation to switch to defection when doing so is payoff-maximizing. We 
find that sparser networks (i.e., smaller average degree) facilitate the 
success of dual-process cooperators over intuitive defectors, while also 
reducing the level of deliberation that dual-process cooperators engage 
in; and that these results generalize across different kinds of networks. 
These observations demonstrate the important role that spatial structure 
can have not just on the evolution of cooperation, but on the co-evolution 
of cooperation and cognition.

Synergy from reproductive division of labor and genetic complexity drive the evolution of sex

    Computer experiments that mirror the evolutionary dynamics of sexual 
and asexual organisms as they occur in nature were used to test features 
proposed to explain the evolution of sexual recombination. Results show 
that this evolution is better described as a network of interactions 
between possible sexual forms, including diploidy, thelytoky, facultative 
sex, assortation, bisexuality, and division of labor between the sexes, 
rather than a simple transition from parthenogenesis to sexual 
recombination. Diploidy was shown to be fundamental for the evolution of 
sex; bisexual reproduction emerged only among anisogamic diploids with a 
synergistic division of reproductive labor; and facultative sex was more 
likely to evolve among haploids practicing assortative mating. Looking at 
the evolution of sex as a complex system through individual-based 
simulations explains better the diversity of sexual strategies known to 
exist in nature, compared to classical analytical models.

Resisting Influence: How the Strength of Predispositions to Resist Control Can Change Strategies for Optimal Opinion Control in the Voter Model

In this paper, we investigate influence maximization, or optimal opinion control, in a modified version of the two-state voter dynamics in which a native state and a controlled or influenced state are accounted for. We include agent predispositions to resist influence in the form of a probability q with which agents spontaneously switch back to the native state when in the controlled state. We argue that in contrast to the original voter model, optimal control in this setting depends on q: For low strength of predispositions q, optimal control should focus on hub nodes, but for large q, optimal control can be achieved by focusing on the lowest degree nodes. We investigate this transition between hub and low-degree node control for heterogeneous undirected networks and give analytical and numerical arguments for the existence of two control regimes.

Financial networks and stress testing: Challenges and new research avenues for systemic risk analysis and financial stability implications

    Network models, stress testing methods and early warning systems are attracting growing interest both among scholars and practitioners. In this short paper, we illustrate some of the insights they have to offer both in terms of new fundamental scientific understanding of the emergence systemic risk and in terms of concrete applications to the policy areas of financial stability and macro-prudential policy. Finally, we discuss new research pathways to address the challenging questions still open, including multiplex networks, big financial data, and climate-finance.
