We study a sequential trading financial market where there are gains from trade, that is, where informed traders have heterogeneous private values. We show that an informational cascade (i.e., a complete blockage of information) arises and prices fail to aggregate information dispersed among traders. During an informational cascade, all traders with the same preferences choose the same action, following the market (herding) or going against it (contrarianism). We also study financial contagion… Expand

Transaction Costs and Informational Cascades in Financial Markets: Theory and Experimental Evidence
We study the effect of transaction costs (e.g., a trading fee or a transaction tax, like the Tobin tax) on the aggregation of private information in financial markets. We analyze a financial market aExpand
Transaction costs and informational cascades in financial markets
We study the effect of transaction costs (e.g., a trading fee or a transaction tax, like the Tobin tax) on the aggregation of private information in financial markets. We implement a financial marketExpand
Informational Contagion in the Laboratory
We study the informational channel of financial contagion in the laboratory. In our experiment, two markets with correlated fundamentals open sequentially. In both markets, subjects receive privateExpand
HERD INDUCED BY UNINFORMED TRADERS IN EFFICIENT FINANCIAL MARKETS
Rational herd is usually regarded to be difficult, if not impossible, to take place in an efficient financial market. In an extension of a sequential unit trading model, we find that large numbers ofExpand
Herding, contrarianism and delay in financial market trading : a lab experiment
Economic theory routinely assumes rational trading and efficient prices, but these two may contradict each-other: rational traders will seek to observe each-other and through Bayesian inference inferExpand
Informational Contagion in the Laboratory
We study the informational channel of financial contagion under laboratory conditions. In our experiment, two markets with correlated fundamentals open sequentially and in both of them subjectsExpand

Informational contagion in the laboratory
We study the informational channel of financial contagion in the laboratory. In our experiment, two markets with privately informed subjects open sequentially. Subjects in the second market observeExpand
A Baseline Model of Price Formation in a Sequential Market
In a centralized market where information over the fundamental value of a traded asset is asymmetric and imperfect a basic question arises: how well the market price transmits and aggregates disperseExpand
Institutional Trades and Herd Behavior in Financial Markets
The article studies the impact of transaction costs on the trading strategy of informed institutional investors in a sequential trading market where traders can choose to transact a large or a smallExpand

Herding and price convergence in a laboratory financial market
We study whether herding can arise in a laboratory financial market in which agents trade sequentially. Agents trade an asset whose value is unknown and whose price is efficiently set by a marketExpand

Contagion as a Wealth Effect
Financial contagion is described as a wealth effect in a continuous-time model with two risky assets and three types of traders. Noise traders trade randomly in one market. Long-term investorsExpand

The authors study the relationship between asset prices and herd behavior, which occurs when traders follow the trend in past trades. When traders have private information on only a single dimensionExpand
Reputation and Asset Prices: A Theory of Information Cascades and Systematic Mispricing
What are the equilibrium features of a dynamic financial market where traders care about their reputation for ability? We modify a standard sequential trading model to study a financial market withExpand
Information aggregation in financial markets with career concerns
TLDR
This work characterize the most revealing equilibrium of this game and shows that an increase in the strength of the traders' reputational concerns has a negative effect on the extent of information that can be revealed in equilibrium but a positive effect on market liquidity. Expand

Herd Behavior in a Laboratory Financial Market
We study herd behavior in a laboratory financial market. Subjects receive private information on the fundamental value of an asset and trade it in sequence with a market maker. The market makerExpand

We study the extent to which, in a laboratory financial market, noise trading can stem from subjects' irrationality. We estimate a structural model of sequential trading by using experimental data.Expand
