N early 40 years ago W. D. Hamilton (1) published his classic paper on the genetic evolution of social behavior. His mathematical theory of kin selection and the related concept of inclusive fitness played a major role in redirecting the evolutionary study of social behavior and accounting for apparently altruistic phenotypes observed in nature. Since that time, and especially after publication...

A familial vulnerability to schizophrenia is agreed even though the exact genes involved seem elusive. But despite epidemiological evidence showing different rates of schizophrenia in sociocultural groups that would be considered genetically similar, the causal role of the environment is still hotly contested.

Bayesian agents learn about a moving target, such as a commodity price, using private signals and their network neighbors’ estimates. The weights agents place on these sources of information are endogenously determined by the precisions and correlations of the sources; the weights, in turn, determine future correlations. We study stationary equilibria—ones in which all of these quantities are c...

Abstract In the past decades, human activities caused global Earth system changes, e.g., climate change or biodiversity loss. Simultaneously, these associated impacts have increased environmental awareness within societies across globe, thereby leading to dynamical feedbacks between social and natural system. Contemporary modelling attempts of dynamics rarely incorporate such co-evolutions inte...

The rapidly growing and evolving literature on the social environment and its influence on health outcomes currently lacks a clear taxonomy of dimensions of the social environment and the differing mechanisms through which each influences health-related behavior. This paper identifies five dimensions of the social environment-social support and social networks, socioeconomic position and income...
