Online escrow is an emerging trust service in consumer-to-consumer auction markets to protect online traders from Internet fraud. This paper reports an empirical study on the factors affecting traders’ risk perception and their adoption of online escrow service.

In this paper, we model a specialist call market. Liquidity traders and a strategic informed trader submit market orders. Strategic value traders compete with the specialist through the limit order book. Noise is introduced into the book through the number of value traders. We compare an equilibrium in an open limit order book environment with an equilibrium in a closed limit order book environ...

An Object-Z formal speci cation of the ODP Trader is presented which concisely captures the hierarchical context structure, the distribution of information and the communication aspects of the Trader. Particular use is made of generic classes, class inheritance and object aggregation (i.e. the instantiation of collections of similar objects) to give a structured speci cation that can be readily...

This paper studies a risk-sharing model where traders face endowment shocks and information asymmetries. We show that a negative participation externality arises due to the endogenous information aggregation by prices, and it creates a counter force to a standard positive externality of risk-sharing. As a result, the optimal market size that maximizes gains from trade per trader is finite. The ...
