This article examines the effect of access obligation on mobile network investment. Access obligation is a form of regulated network access in wholesale markets that commits MNOs to grant non-discriminatory access to MVNOs. While it is often claimed that such regulation might lower investment...

Preferences for reciprocity of the Falk-Fischbacher type are applied to a game of trust. After deriving the reciprocity equilibrium, the evolution of preferences is analysed showing that a medium level of reciprocity is evolutionary stable. If players exhibit different inclinations regarding...

A within-subject designed experiment with six games and a total of seven choices is used to test the hypothesis of consistency of other-regarding motives. By the large number of choices, which are mostly belief-independent, one can test the hypothesis that social preferences have a consistent...

In this work, I study the question of whether social preferences are likely to be game specific or not. While theoretical models typically assume universal preference parameters valid across multiple domains, indirect evolutionary models support diverse parameters especially across the dictator,...

In this paper, an indirect evolutionary version of the game of trust is studied. A population consisting of trustworthy and exploitive players is assumed. Players are chosen randomly from the population and are matched with either strangers or players they know in order to play the game of...
