| Abstract: | The growing importance of online social networks makes it interesting to ask whether extant social capital can substitute for trust built through repeated interactions. It also provides fertile ground for researchers seeking to gain a deeper understanding of fundamental constructs of human behavior, such as trust, forgiveness, and their linkage to social ties. In both contexts, a challenge in the literature on repeated interactions and social ties is the econometric task of accounting for endogenous social ties. The reality, and possible confound, is that repeated interactions may create a context in which social ties can emerge as the outcome of a sustained social relationship. To address the challenge of endogenous social ties, we design a field experiment that uses data from the Facebook API to measure social ties that connect our subjects, and find that the level of trust and forgiveness, and the effect of forgiveness on deterring future defections, crucially depend on the presence of social ties. |

| Abstract: | Reproductive success and survival are influenced by wealth in human populations. Wealth is transmitted to offsprings and strategies of transmission vary over time and among populations, the main variation being how equally wealth is transmitted to children. Here we propose a model where we simulate both the dynamics of wealth in a population and the evolution of a trait that determines how wealth is transmitted from parents to offspring, in a darwinian context. |

| Abstract: | Socio-economic inequalities are manifested in different aspects of our social life. We discuss various aspects, beginning with the evolutionary and historical origins, and discussing the major issues from the social and economic point of view. The subject has attracted scholars from across various disciplines, including physicists, who bring in a unique perspective to the field. The major attempts to analyze the results, address the causes, and understand the origins using statistical tools and statistical physics concepts are discussed. |
