A large market economy has a huge number of degrees of freedom with weak microlevel coordination. The ‘implicit microfoundations’ approach considers this property of micro-level interactions to more strongly determine macro-level outcomes compared to the precise details of individual choice behavior; that is, the ‘particle’ nature of individuals dominates their ‘mechanical’ nature. So rather th...

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 learning converged to the Walrasian, competitive equilibrium. Vriend (2000) reports that the model of s...

The &as if ' view of economic rationality defends the pro"t maximization hypothesis by pointing out that only those "rms who act as if they maximize pro"ts can survive in the long run. Recently, the problem of arriving at a logically consistent de"nition of rational behavior in games has shown that one must sometimes study explicitly the evolutionary processes that form the basis of this view. ...

The isoelectric point of the K99 antigen in partially purified preparations isolated from Escherichia coli B41 was 4.2. Electrofocused K99 antigen hemagglutinated guinea pig and sheep erythrocytes and gave a single precipitin line on diffusion against antisera to E. coli B41 and absorbed factor K99 antisera.

Some analyses of the single pion production in -:::-N collision1> have been made to find the evidence of the boson isobars2> of the Sakata model. From these ar:alyses jt has been suggested that the boson isobar with I= 2, i.e. B41 (0, 2) of the Sakata model, exists and t as the 2-:::-decay mode. The B41 (0, 2) isobar is, then, expected to have the effect to the pionic decay of kaon. Especially ...
