Many information structures generate correlated rather than mutually independent signals, the news media being a prime example. This paper shows experimentally that in such context many people neglect these correlations in the updating process and treat correlated information as independent. In...

We investigate the impact of agent communication networks on prices in an artificial stock market. Networks with different centralization measures are tested for their effect on the volatility of prices. Trading strategies diffuse through the different network topologies, mimetic contagion...

What return should you expect when you take on a given amount of risk? How should that return depend upon other people's behavior? What principles can you use to answer these questions? In this paper, we approach these topics by exploring the consequences of two simple hypotheses about risk.The...

Although the pure economic loss rule has been remarkably durable in the common law, it suffers from a theoretical deficit. The rule has not been properly framed within the broader context of Anglo-American political economy. Any theory must recognize that the rule fundamentally deals with...

This paper intends to contribute to the theoretical literature on the determinants of exchange rate fluctuations. We build an agent-based model, based on behavioral assumptions inspired by the literature on behavioral finance and by empirical surveys about the behavior of foreign exchange...

This paper examines how market prices, volume, and traders' dividend expectations respond to public information releases in laboratory markets for a long-lived financial asset. The objective is to study deviations from the symmetric information risk-neutral rational expectations (RE) benchmark,...
