We introduce a microscopic model of double-auction markets based on random order placement. Traders post market or limit orders which are stored in the book of the exchange and executed via a central order matching mechanism. We use dimensional analysis, simulations and analytical approximations...

We study the phenomenon of internal avalanching within the context of recently proposed “Tetris” lattice models for granular media. We consider a packing of particles subjected to two different dynamics. In the first case, we arrest the system at different instances during an “aging”...

Previous research on the factors that influence a business's participation in third party e-markets identified a set of motivational and ability related factors. This paper explores further the question of the determinants of third party e-market participation using a multiple case study...
