The puzzling evidence of seemingly high momentum returns is related to an understanding of risk as a simple covariance. If we consider, however, risk in higher-order statistical moments, momentum returns appear less advantageous. Thus, a prospect-theoretical assessment of US stock momentum...

We report results of an internet experiment designed to test the theory of informational cascades in financial markets (Avery and Zemsky, AER, 1998). More than 6000 subjects, including a subsample of 267 consultants from an international consulting firm, participated in the experiment. As...

DeLong (1990a) et al. show that in the presence of positive feedback traders rational speculation can be destabilizing, in that it drives the price of a risky asset above its expected value. A generalization of their seminal model with additional trading dates and an additional informative...

This paper reports the results of 18 experimental asset markets with 262 subjects that explore the effects of liquidity and aggregation of information. The main focus lies on the comparison of different trading mechanisms of stock exchanges. Compared to most of financial markets experiments,...

This paper tests the random walk hypothesis and market efficiency for twelve emerging as well as for four developed securitized real estate markets from 1992 to 2009. Random walk properties of equity prices influence return dynamics, and market efficiency is often considered an essential...

This study seeks to explore, how market efficiency changes, if ordinary traders receive fundamental news more or less often. We show that longer temporal information gaps lead to fewer but larger shocks and a reduction of the average noise level on the dynamics. The consequences of these effects...

This paper reports the results of 13 experimental asset markets with 195 subjects that explore the effects of insider behavior on the price formation process and market liquidity. The experimental call markets use a more realistic design than related studies. We introduce infinitely-lived assets...

Although China now has one of the largest government bond markets in the world, the market has received relatively little attention and analysis. We describe the history and structure of the market and assess its functioning. We find that trading in individual bonds was historically sparse but...

This paper is concerned with empirical and theoretical basis of the Efficient Market Hypothesis (EMH). The paper begins with an overview of the statistical properties of asset returns at different frequencies (daily, weekly and monthly), and considers the evidence on return predictability, risk...
