AB - We propose and study a simple stochastic model for the dynamics of a limitorder book, in which arrivals of market order, limit orders and ordercancellations are described in terms of a Markovian queueing system. Throughits analytical tractability, the model allows to obtain analytical expressionsfor various quantities of interest such as the distribution of the durationbetween price changes, the distribution and autocorrelation of price changes,and the probability of an upward move in the price, {\it conditional} on thestate of the order book. We study the diffusion limit of the price process andexpress the volatility of price changes in terms of parameters describing thearrival rates of buy and sell orders and cancelations. These analytical resultsprovide some insight into the relation between order flow and price dynamics inorder-driven markets.
