We present an experimental information market designed to aggregate IT job related information distributed among the traders in the market. The payoffs of the shares in this market were tied to true IT job demand in the real world. This paper focuses on the market outcomes of profit or loss made in this market, and more specifically the factors that may lead to either outcome. We explore the us...

In a bilateral oligopoly, with large traders, represented as atoms, and small traders, represented by an atomless part, when is there a non-empty intersection between the sets of Walras and Cournot-Nash allocations? Using a two commodity version of the Shapley window model, we show that a necessary and sufficient condition for a CournotNash allocation to be a Walras allocation is that all atoms...

Risks faced by traders from price movements are sometimes magnified by the actions of other traders. Riskmanagement systems which neglect this feature may give a seriously misleading picture of the true risks. The hazards arising from this potential blindspot are at their most dangerous when the prevailing conventional wisdom lulls traders into a false sense of security on the attractiveness of...

This paper analyzes the market for financial information and the incentive of institutions, such as Reuters, to provide information to traders in decentralized financial markets. We derive the following results. (i) The optimal selling strategy consists of selling identical information (Reuters’ screen) to all traders. (ii) The traders buy information from the same providers. If the traders may...

This paper uses an equilibrium model to study how institutional investors in uence the volatility and the informativeness of asset prices. The growth in the proportion of U.S. equities owned by institutions in the past two decades, their resulting dominant position in nancial markets, and empirical evidence that institutional ownership may increase volatility warrant studying this issue from a ...

In this paper we extend the original heterogeneous agent model by introducing smart traders and changes in agents’ sentiment. The idea of smart traders is based on the endeavor of market agents to estimate future price movements. By adding smart traders and changes in sentiment we try to improve the original heterogeneous agents model so that it provides a closer description of real markets. Th...

Successful animal systems often manage risk through synchronous behavior that spontaneously arises without leadership. In critical human systems facing risk, such as financial markets or military operations, our understanding of the benefits associated with synchronicity is nascent but promising. Building on previous work illuminating commonalities between ecological and human systems, we compa...

In many studies the assumption is made that traders only encounter one type of price risk. In reality, however, traders are exposed to multiple price risks, and often have several relevant derivative instruments available with which to hedge price uncertainty. In this study, commodity, foreign exchange, and freight futures contracts are analyzed for their effectiveness in reducing price uncerta...
