Kaminski, Marek M.2020-03-042020-03-042019Studia Metodologiczne, nr 39, 2019, s. 171–193.0039424Xhttp://hdl.handle.net/10593/25474This article discusses how the developments in game theory and social choice theory profoundly transformed our understanding and modeling of social rationality in the social sciences due to the erosion of the concept of social optimum.
