A hybrid of a model of economic equilibrium in two markets and a social game is formed. The link between the two is established through a social norm which conditions correct social behavior on economic variables and therefore distorts the economic equilibrium allocation. The initial endowment...

Lotka-Volterra equations which equivalent to the replicator equation in evolutionary game theory under mathematical dynamic ecosystem model will provide the new basic behavior of network services. The FTTH-DSL market in Japan shifted from the co-existence model of horizontal market to the...

We consider a basic stochastic evolutionary model with rare mutation and a best-reply (or better-reply) selection mechanism. Following Young's papers, we call a state stochastically stable if its long-term relative frequency of occurrence is bounded away from zero as the mutation rate decreases...

There is continuing debate about what explains cooperation and self-sacrifice in nature and in particular in humans. This paper suggests a new way to think about this famous problem. I argue that, for an evolutionary biologist as well as a quantitative social scientist, the triangle of two...

We introduce a generalized theoretical approach to study imitation models and subject themodels to rigorous experimental testing. In our theoretical analysis we find that the differentpredictions of previous imitation models are due to different informational assumptions, notto different...

In a coordination game such as the Battle of the Sexes, agents can condition their plays on external signals that can, in theory, lead to a Correlated Equilibrium that can improve the overall payoffs of the agents. Here we explore whether boundedly rational, adaptive agents can learn to...
