This paper studies information aggregation in pure common value double auctions with a continuum of traders. This trade environment captures some of the main features of prediction markets. The population includes both sophisticated and näıve traders whose bidding behavior is not influenced by opponents’ equilibrium strategies. Existence and uniqueness of monotone equilibrium prices is shown un...

In an environment of Over-The-Counter trading with asymmetric information about the quality of the counterparty, we study traders’ incentives to screen their counterparties under different clearing arrangements. When traders can choose the clearing arrangement, they decide which types of transactions to clear under each arrangement, with significant consequences for transparency and collateral ...

A descriptive cross-sectional survey was carried out among a total sample of 281 women in Sango market, Ibadan in, 2003. Fe...

BACKGROUND In Western settings, the relationship between trauma history, posttraumatic stress disorder, substance use, and HIV risk behavior, is well established. Although female fish traders in Zambia are affected by HIV at rates estimated to be 4-14 times higher than the national prevalence, no studies have examined the co-occurring issues of trauma, substance use and HIV risk behavior among ...

Regulators and actors in international trade are facing a difficult challenge of increasing control and security while at the same time lowering the administrative burden for traders. As a tentative response, the European Commission has introduced the concept of “trusted traders”: certified traders that are in control of their business. Trusted traders are entitled to trade facilitations, faste...

In this paper we propose a model of decentralized federation of traders. Each component trader manages its own set of federated traders. A federation contract is used to document the agreement between two federating traders. The importer's portion of the federation contract forms an import contract that states the service types available in the remote trader. The exporter's portion of the feder...

On markets with receding prices, artificial noise traders may consider alternatives to buy-and-hold. By simulating variations of the Parrondo strategy, using real data from the Swedish stock market, we produce first indications of a buylow-sell-random Parrondo variation outperforming buy-and-hold. Subject to our assumptions, buy-low-sell-random also outperforms the traditional value and trend i...

Traders in a market typically have widely different, private information on the return of an asset. The equilibrium price of the asset may reflect this information more accurately if the number of traders is large enough compared to the number of the states of the world that determine the return of the asset. We study the transition from markets where prices do not reflect the information accur...

We analyze a model in which traders have different trading opportunities and learn information from prices. The difference in trading opportunities implies that different traders may have different trading motives when trading in the same market—some trade for speculation and others for hedging—and thus they may respond to the same information in opposite directions. This implies that adding mo...
