This paper finds that fund managers do not expect mean reverting returns, as suggested by theory and empirical evidence, but mean averting returns. The degree of mean aversion is positively related to preferences for non-fundamental information and loss aversion.

This paper examines whether NASDAQ dealers' preopening quotes might be related to non-fundamental information, that is, information about transient trading pressure un- related to fundamentals.

Evidence suggests that arbitragers exchange investment ideas. We analyze why and under what circumstances sharing occurs. Our model suggests that sharing ideas will lead to the following: more efficient asset prices, larger arbitrager profits, and correlated arbitrager returns. We predict that...

In this paper we are preoccupied by a study of trust and loss aversion on Romanian capital market. In global financial depreciation of stocks the emergent markets are much more affected that the lack of money and investors aversion. Based on efficient market theory we study the evolution of...

This paper analyses the statistical behavior of the US dollar, against nine different currencies, over the float period, with a monthly data set. The martingale hypothesis is rejected for all currencies. However, all currencies have a unit root. There is overwhelming evidence for significant...

This study compares and contrasts the multiple characterizations of mean reversion in financial time series as regards the restrictions they imply. This is accomplished by translating them into statements about an alternative measure, the "Average Crossing Time" or ACT. We argue that the ACT...

In this paper, I relax the common assumption of the one-dimensionality of noise made in the standard competitive noisy rational expectations framework. Within an environment characterized by multidimensional noise, I explore the strategic interactions between different traders that are informed...

Do all types of information benefit the efficiency of prices in the sense that they drive them closer to fundamentals compared to the situation where information does not exist? Looking at the competitive noisy rational expectations framework, the clear answer of the literature is: yes. It...
