A number of robust and diagnostic techniques for the linear regression are in terms of "p"-dimensional subsets of the original sample. In a sample of size "n" this leads to consider C[superscript n][subscript p] subsets. To reduce the computational burden, a limited number of subsets can be...

We examine the Cournot oligopoly model in the context of social and individual learning. In both models of learning, firms update their decisions about how much to produce via variants of the genetic algorithm updating procedure. Arifovic (1994) found that both models of social and individual...

In evolutionary psychology, cultural phenomena are explained with reference to evolved psychological processes. This paper presents an economic approach to explore this link by demonstrating how social stratification can arise in game-playing populations as a result of social categorisation of...

In non-cooperative models of coalition formation, players have to decide whether or not to participate in a coalition (alliance). Game theoretic analyses of the formation of alliances in games with externalities, stress the difficulties in designing self-enforcing treaties because of...
