I study how sequential entry into an arbitrage affects the liquidity of underlying assets and the speed of arbitrage. Incumbent arbitrageurs exploit a mispricing between two identical but imperfectly liquid assets. Because of market thinness, incumbent arbitrageurs trade slowly to limit their...

Theories of predatory trading assume exogenous market depth and/or exogenous distress of the prey. By endogenizing both, I obtain a new feedback loop between liquidity and predatory trading. On the one hand, limited depth helps predators move prices to push the prey into distress. On the other...

Many arbitrage strategies are dominated by a few large arbitrageurs who recognize their price impact. I model arbitrageurs as imperfectly competitive intermediaries facilitating risk-sharing between two clienteles of competitive investors. I show that in the presence of market power, i)...

I study how financial constraints affect liquidity provision and welfare under different structures of the arbitrage industry. In competitive markets, financial constraints may impair arbitrageurs' ability to provide liquidity, thereby reducing other investors' welfare. Instead, in imperfectly...

I study how (VaR-based) financial constraints affect liquidity and welfare under different structures of the arbitrage industry. When capital is spread across numerous competitive arbitrageurs, financial constraints may impair their ability to provide liquidity, lowering other investors'...

I study the price/quantity effects of anticipated supply or demand shocks in a model of strategic trading, where imperfectly competitive traders share risk with price-takers. When there are at least two traders, anticipated shocks lead to the V-shaped pattern observed empirically: prices drift...
