Using jointly geometric and stochastic reformulations of nonconvex problems and exploiting a Monge-Kantorovich gradient system formulation with vanishing forces, we formally extend the simulated annealing method to a wide class of global optimization methods. Due to an inbuilt combination of a...

We develop a model of within-firm sequential, directed search and study a firm’s ability and incentive to steer consumers. We find that the firm often benefits from adopting a noisy positioning strategy, which limits the information available to consumers. This induces consumers to keep searching...

Urban outputs, from economy to innovation, are known to grow as a power of a city's population. But, since large cities tend to be central in transportation and communication networks, the effects attributed to city size may be confounded with those of intercity connectivity. Here, we map intercity...

We argue that education's effect on political participation in developing democracies depends on the strength of democratic institutions. Education increases awareness of, and interest in, politics, which help citizens to prevent democratic erosion through increased political participation. We...

Researchers investigating the evolution of human aggression look to our closest living relatives, bonobos (Pan paniscus) and chimpanzees (Pan troglodytes), as valuable sources of comparative data.1,2 Males in the two species exhibit contrasting patterns: male chimpanzees sexually coerce females3,4,...

The use of expectiles in risk management has recently gathered remarkable momentum due to their excellent axiomatic and probabilistic properties. In particular, the class of elicitable law-invariant coherent risk measures only consists of expectiles. While the theory of expectile estimation at...

Industrialized environments, despite benefits such as higher levels of formal education and lower rates of infections, can also have pernicious impacts upon brain atrophy. Partly for this reason, comparing age-related brain volume trajectories between industrialized and non-industrialized...

Opinion patterns are affected by cognitive biases and noise. While mathematical models have focused extensively on biases, we still know surprisingly little about how different types of noise shape opinion patterns. Here, we use an agent-based opinion dynamics model to investigate the interplay...

We analyze the political impact of a generous solar panel subsidization program. Subsidies far exceeded their social benefit and were partly financed by new taxes on adopters and by electricity surcharges for all consumers. We use local panel data from Belgium and find a decrease in votes for...

Young children and adolescents in subsistence societies forage for a wide range of resources. They often target child‐specific foods, they can be very successful foragers, and they share their produce widely within and outside of their nuclear family. At the same time, while foraging, they face...
