The workshop (mini-conference) is aimed to present and discuss contemporary research on human behaviour in individual and interactive settings, from both theoretical and experimental points of view. Having as a benchmark the traditional economics assumption of rational behaviour, contemporary researchers draw more attention to procedural decision-making, boundedly rational perception and learning, psychological aspects of individual and collective actions. The workshop will be the first academic event of that kind in Russia, and it will call participation of the leading international academics working in this area.
