In infinite horizon economies only local equivalence of beliefs is needed to ensure the existence of an Arrow–Debreu equilibrium. In fact, agents can even disagree completely in the long run in the sense that asymptotically, their beliefs are singular. Copyright Springer-Verlag Berlin...

Brown and von Neumann introduced a dynamical system that converges to saddle points of zero sum games with finitely many strategies. Nash used the mapping underlying these dynamics to prove existence of equilibria in general games. The resulting Brown-von Neumann-Nash dynamics are a benchmark...

The influence of heterogeneous time preferences on the term structure is studied in the framework of a continuous-time pure exchange economy, in which agents have, apart from differential time preferences, the same degree of relative risk aversion. A closed-form solution for the financial...
