This paper provides a set of criteria to evaluate the usability of trader user interfaces with respect to resource discovery. The criteria were identified because trader user interface developers sometimes make unrealistic assumptions about the information seeking behavior of their users, leading to interfaces that are difficult to use for resource discovery. This paper uses some insights from ...

The presence of information asymmetry increases the probability that a potential predator will provide liquidity rather than engaging in predatory trading during liquidation by a distressed trader. More information asymmetry is associated with lower expected losses from liquidation for the distressed trader in illiquid markets. There is a negative correlation between the degree of information a...

We introduce human traders into an agent based financial market simulation prone to bubbles and crashes. We find that human traders earn lower profits overall than do the simulated agents (“robots”) but earn higher profits in the most crash-intensive periods. Inexperienced human traders tend to destabilize the smaller (10 trader) markets, but have little impact on bubbles and crashes in larger ...

The von Neumann-Morgenstern concept of solution is applied to nonatomic pure exchange markets consisting of a finite number of different types of trader, initially owning disjoint sets of goods. It is proved that if all traders of each type form a cartel and behave like a single (atomic) trader (their "representative"), then one gets solutions of the original market from those of the finite mar...

Dynamic invocation of services in O-O execution environments requires identification of server objects which are “fit” to a certain task on the basis of available functional and non-functional information. CORBAcompliant environments store such information in a Trader system which can be browsed or queried by client objects. In this paper a fuzzy data model is proposed as the basis of the desig...

The success of the internet has made some dramatic changes in the way scientists and students are supplied with scientific literature. It has started to change into an information market, where the value of a piece of information is determined by the law of supply and demand. The customer in this market is unable to find providers delivering the desired piece of information under the his/her co...
