This paper analyses the impact of a minimum price variation (tick) and time priority on the quote dynamics and on trading costs when competition for the order flow is dynamic. It finds that convergence to competitive prices can take time and that the speed of convergence is influenced by the...

We analyze the impact of a minimum price variation (tick) and time priority on the dynamics of quotes and the trading costs when competition for the order flow is dynamic. We find that convergence to competitive outcomes can take time and that the speed of convergence is influenced by the tick...

We analyze price competition between dealers in a security market where the bidding process is sequential. The model provides an interpretation for the evolution of the best ask and bid prices, in-between transactions. We find that convergence to the competitive ask and bid prices can take time....
