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...

This paper provides a game theoretic model of price formation and order placement decisions in a dynamic limit order market. Investors can choose to post limit orders or to submit market orders. Limit orders result in better execution prices but face a risk of non-execution and a winner’s...

In many security markets, dealers trade with their regular clients at a discount relative to prevailing bid and ask quotes. In this article we provide an explanation to this phenomenon. We consider a dealer and an investor engaged in a long-term relationship. The dealer assigns a reputational...

We describe a new mechanism that explains the transmission of liquidity shocks from one security to another ("liquidity spillovers"). Dealers use prices of other securities as a source of information. As prices of less liquid securities convey less precise information, a drop in liquidity for...

We show that the sensitivity of corporate investment to stock price is higher for firms cross-listed in the U.S. than for firms that never cross-list. This difference is strong, does not exist prior to the cross-listing date, and does not vanish over time after this date. Moreover, the impact of...

We study competition between a dealer (OTC) market and a limit order market. In the limit order market, investors can choose to be "makers" (post limit orders) or "takers" (hit limit orders) whereas in the dealer market they must trade at dealers' quotes. Moreover, in the limit order market,...

We develop a dynamic model of an order-driven market populated by discretionary liquidity traders. These traders must trade, yet can choose the type of order and are fully strategic in their decision. Traders differ in their impatience: less patient traders demand liquidity, more patient traders...

We test the hypothesis that individual investors contribute to the idiosyncratic volatility of stock returns because they act as noise traders. To this end, we consider a reform that makes short selling or buying on margin more expensive for retail investors relative to institutions, for a...

High frequency arbitrage opportunities sometimes arise when the price of one asset follows, with a lag, changes in the value of another related asset due to information arrival. These opportunities are toxic because they expose liquidity suppliers to the risk of being picked off by arbitrageurs....

We develop a dynamic model of a market with two specialized sides: traders posting quotes ("market makers") and traders hitting quotes ("market takers"). Traders monitor the market to seize profit opportunities, generating high frequency liquidity cycles. Monitoring decisions by market-makers...
