October 2011Liquidity and the Threat of Fraudulent Assets
with Yiting Li, Pierre-Olivier Weill: w17500
We study an over-the-counter (OTC) market with bilateral meetings and bargaining where the usefulness of assets, as means of payment or collateral, is limited by the threat of fraudulent practices. We assume that agents can produce fraudulent assets at a positive cost, which generates endogenous upper bounds on the quantity of each asset that can be sold, or posted as collateral in the OTC market. Each endogenous, asset-specific, resalability constraint depends on the vulnerability of the asset to fraud, on the frequency of trade, and on the current and future prices of the asset. In equilibrium, the set of assets can be partitioned into three liquidity tiers, which differ in their resalability, their prices, their sensitivity to shocks, and their responses to policy interventions. The dep...

October 2009Crises and Liquidity in Over-the-Counter Markets
with Ricardo Lagos, Pierre-Olivier Weill: w15414
We study the efficiency of dealers’ liquidity provision and the desirability of policy intervention in over-the-counter (OTC) markets during crises. Our theory emphasizes two key frictions in OTC markets: finding counterparties takes time, and trade is bilateral, with quantities and prices determined by bargaining. We model a crisis as a negative shock to investors’ asset demands that lasts until a random recovery time. In this context, dealers can provide liquidity to outside investors by acting as counterparties in trades and by accumulating asset inventories. We find that, when frictions are severe, even well capitalized dealers may not find it optimal to accumulate inventories, given that investors choose asset positions that require small reallocations. In such circumstances, the mark...

June 2008Crashes and Recoveries in Illiquid Markets
with Ricardo Lagos, Pierre-Olivier Weill: w14119
We study the dynamics of liquidity provision by dealers during an asset market crash, described as a temporary negative shock to investors aggregate asset demand. We consider a class of dynamic market settings where dealers can trade continuously with each other, while trading between dealers and investors is subject to delays and involves bargaining. We derive conditions on fundamentals, such as preferences, market structure and the characteristics of the market crash (e.g., severity, persistence) under which dealers provide liquidity to investors following the crash. We also characterize the conditions under which dealers incentives to provide liquidity are consistent with market efficiency.
