This paper describes the relationship between bounded rationality and risk aversion. It shows athat bounded rationality increases risk aversion at the reference income level and that there exists an income level below the reference income level where bounded rationality reduces risk aversion and...

This survey summarises the recent theoretical developments in understanding price processes. After introducing the rational expectations equilibria (REE) concept the limitations of this approach are shown. We illustrate the relationship between partially-revealing REE and incomplete markets and...

This paper considers a two country economy similar to that in Obstfeld and Rogoff (1995). We build on their model by distinguishing between sticky retail prices, sticky wholesale prices and sticky wages. We find that conclusions about whether monetary shocks lead to exchange rate overshooting...

We use a rational expectations model to examine how public disclosure requirements affect listing decisions by rent-seeking corporate insiders, and allocation decisions by liquidity traders seeking a minimize trading costs. We find that exchanges competing for trading volume engage in a ¶race...

We present a model in which an asset bubble can persist despite the presence of rational arbitrageurs. The resilience of the bubble stems from the inability of arbitrageurs to temporarily coordinate their selling strategies. This synchronization problem together with the individual incentive to...

This paper reviews some of the most prominent asset price bubbles from the past 400 years and documents how central banks (or other institutions) reacted to those bubbles. The historical evidence suggests that the emergence of bubbles is often preceded or accompanied by an expansionary monetary...

Human beings want to believe that good outcomes in the future are more likely, but also want to make good decisions that increase average outcomes in the future. We consider a general equilibrium model with complete markets and show that when investors hold beliefs that optimally balance these...
