Here, we present some experiments of non-cooperative games of network formation based on Bala and Goyal (Econometrica 68:1181–1229, 2000 ). We have looked at the one-way and the two-way flow models, each for high and low link costs. The models come up with both multiple equilibria and coordination problems. We conducted the experiments under various conditions which allowed for repeated interactions between subjects. We found that coordination on non-empty Strict Nash equilibria was not an easy task to achieve, even in (...) the one-way model where the Strict Nash equilibria are wheels. We found some evidence of convergence to equilibrium networks through learning dynamics, while we found no effect of salient labels to help coordination. The evidence on learning behavior provides support for subjects that were choosing strategies in line with various learning rules, principally Reinforcement and Fictitious Play. (shrink)
Segal (1987) suggested that the Ellsberg paradox might be explained in terms of individuals mentally representing the decision problem as a two-stage lottery which they evaluated according to a non-expected utility model. This paper describes an experiment involving an explicitly two-stage analogue to an Ellsberg-type problem. This design substantially reduces the frequency of classic Ellsberg behaviour, but reveals other systematic violations of conventional theory. The paper discusses the particular patterns of choice and raises the more general problem of modelling individual (...) decisions when the reduction principle does not hold. (shrink)
In this paper I investigate a largely untold chapter in the history of race thinking in Northern Europe and North America: the transition from the form of racism that was used to justify a race-based system of slavery to the medicalising racism which called for segregation, apartheid, eugenics, and, eventually, sterilization and the holocaust. In constructing this history I will employ the notion of biopower introduced by Michel Foucault. Foucault’s account of biopower has received a great deal of attention recently, (...) but because what he actually has to say about race tends to be vague and radically incomplete, many race theorists have been critical of his contribution. However, even if the account of the holocaust in terms of biopower is incomplete, there is still a great deal to be learned from Foucault’s identification of this biologizing, or medicalising racism.

In this article, I examine Michele Moody-Adams’ critique of the ‘inability thesis’, according to which some cultures make the resources for criticizing injustice ‘unavailable’ to their members. I investigate Moody-Adams’ alternative ‘affected ignorance’ thesis. Using the example of slavery in ancient Greece, I consider two potential candidates for affected ignorance which involve, respectively, ‘unawareness’ and ‘mistaken moral weighing’; in neither, I hold, may one ascribe culpability to those involved.
For Michele Tosini, the baptism of Christ has profound allusions to Christ's suffering and death. In the Baptism of Christ and Temptations, Tosini is creative in his placement of the temptation narratives and in his selection of the Lukan account.
