The standard state-spaces of asymmetric information preclude non- trivial forms of unawareness (Dekel, Lipman and Rustichini, 1998). We introduce a generalized state-space model that allows for non-trivial unawareness among several individuals, and which satisfies strong properties of knowledge...

Myopic loss aversion (MLA) has been established as one prominent explanation for the equity premium puzzle. In this paper we address two issues related to the effects of MLA on risky investment decisions. First, we assess the relative impact of feedback frequency and investment flexibility (via...

In the context of standard two-period pure-exchange economies with sequential trade, this paper proposes a decentralized coordination mechanism for equilibriumexpectations, facilitated by local interactions between agents. Interactions are modelled stochastically by specifying a family of...

It is a well-known phenomenon that people tend to overestimate their relative abilities. Psychological studies show that a vast majority of people thinks that their ability is above the average when they have to assess their position in a distribution of a target group. We analyse in an...

Economists invoke Mundell (1961) in arguing for the general policy of a flexible exchange rate regime as a means of restoring equilibria after shocks. But there is a discrepancy between the intent of the general policy and attempts at its implementation as identified by specific changes in...

We show that a set of outcomes outside the convex hull of Nash equilibria can be asymptotically stable with respect to convex monotonic evolutionary dynamics. Boundedly rational agents receive signals and condition the choice of strategies on the signals. A set of conditional strategies is...

This paper introduces a new theoretic entity, a nominalist heuristic, defined as a focus on prominent numbers, indices or ratios. Abstractions used in the evaluation stage of decision making typically involve nominalist heuristics that are incompatible with expected utility theory which excludes...

Variance of exchange rates around predictions can be from 1) undiscovered fundamentals, 2) efficient markets, 3) destabilising speculation, or 4) regime and personality differences in the heuristics used in the stage of evaluating alternatives. Field and experimental evidence identifies 4) as...

Conclusions favorable to flexible exchange rates typically accord with expected utility theory in ignoring the costs that exchange rate uncertainty generates for governments, central banks, firms and unions in: (i) choosing among acts; and (ii) existing until learning the outcome of the chosen...

In the decision-making process, there is a stage when choosers evaluate alternatives. Evaluation is complex especially when it involves the future exchange rate. In the complexity of predicting the future exchange rate, choosers may use prominent numbers and ratios. We furnish field and...
