We study behavior in experimental beauty contests with, first, boundary and interior equilibria, and, second, homogeneous and heterogenous types of players. We find quicker and better convergence to the game-theoretic equilibrium with interior equilibria and homogeneous players. -- beauty...

The authors develop and test a model to study the influence of inventory-on-hand and price-based reference points on the consumption rate of consumers. The model is motivated by recent theoretical and empirical research which suggests inventory pressure can cause consumers to increase...

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. -- Heterogeneous expectations ;...
