Moral dilemmas engender conflicts between two traditions: consequentialism, which evaluates actions based on their outcomes, and deontology, which evaluates actions themselves. These strikingly resemble two distinct decision-making architectures: a model-based system that selects actions based on inferences about their consequences; and a model-free system that selects actions based on their re...

This paper uses documentary records of the bromine cartel from 1885 to 1914 to evaluate the contributions of noncooperative, repeated game models of collusion to our understanding of the determinants of cartel success and the causes of price wars. It finds that many of the variables that determine an industry’s ability to collude in these models—the discount rate, the information structure, the...

Abstract What drives Corporate Social Responsibility (CSR) engagement of firms? Most empirical literature on firms’ CSR focuses benefits resulting from which are granted by the public. Other studies argue that firms driven fear negative public reactions. This raises, firstly, question, whether rewards or punishments drive firms. Secondly, how can we find out, more relevant? study starts out obs...

Serotonin's function in the brain is unclear. One challenge in testing the numerous hypotheses about serotonin's function has been observing the activity of identified serotonergic neurons in animals engaged in behavioral tasks. We recorded the activity of dorsal raphe neurons while mice experienced a task in which rewards and punishments varied across blocks of trials. We 'tagged' serotonergic...

Impairment in the serotonergic system has been linked to action choices that are less advantageous in a long run. Such impulsive choices can be caused by a deficit in linking a given reward or punishment with past actions. Here, we tested the effect of manipulation of the serotonergic system by tryptophan depletion and loading on learning the association of current rewards and punishments with ...

Integrating information from existing research, qualitative ethnographic interviews, and participant observation, we designed a field experiment that introduces idiosyncratic environmental risk and a voluntary sharing decision into a standard public goods game. Conducted with subsistence resource users in rural villages on the Kamchatka Peninsula in Northeast Siberia, we find evidence consisten...
