We investigate if the neuropeptide oxytocin (OT), known to moderate social behaviour, influences strategic decision making in social dilemmas by facilitating the integration of incentives and social cues. Participants (N = 29) played two economic games with different incentive structures in the fMRI scanner after receiving OT or placebo (following a double blind, within-subject design). Pictures of angry or neutral faces (the social cues) were ...

The tendency to devalue rewards when offered later in time is known as time discounting and, although universal, shows interindividual differences that are proposed to be dependent on an individuals self-control abilities. In the current study we investigate how the neural correlates of delaying gratification during a time discounting task are associated with individual differences in self-control ability. We assess individual differences on the ...

This study uses fMRI to investigate the cognitive demands of decision-making in two types of cooperation games: a prisoner's dilemma (PD) eliciting a temptation to free-ride, leading to a dominant, self-interested response, and a stag hunt (SH) that has no dominant response but offers pay-off incentives that make mutual cooperation collectively beneficial but risky. Consequently, the PD poses greater conflict between self- and collective ...

We use fMRI to investigate the neurological correlates of two factors that are known to enhance cooperative strategies in social dilemmas: the provision of extrinsic cooperative incentives, and the intrinsic motivation to cooperate. The former is achieved by changing the pay-off matrix of a mixed motive game (e.g., a Prisoners Dilemma, PD) to a coordination game (CG). The latter is achieved by comparing people who differ along the personality ...

In organizational ecology, the focus is on the evolution of a population of organizations. Adopting a similar logic, we deal with the evolution of a population of related inventions. By employing a population perspective to technology, we aim to determine to what extent the pattern of technological growth can be attributed to the structural or systemic characteristics of the technology itself. Through an empirical investigation of patent data in ...

We analyse the patterns and determinants of technology alliance formation with partner firms from emerging economies with a focus on European firms alliance strategies. We examine to what extent European firms alliance formation with partners based in emerging economies is persistent that is, to what extent prior collaborative experience determines new alliance formation and we compare this pattern with alliance formation with developed country ...

Although central network positions have been associated with above average performance effects, an important void that still remains is how firms come to occupy a more central position in the first place. Whereas recently made exogenous explanations have shed some more light on aggregate changes in centrality, they remain silent on an endogenous understanding of how individual firms come to occupy a more central position. To address this, we ...
