Catching falling knives: speculating on market overreaction
No full textMarket participants often invest in order to acquire information that pertains to the market itself (e.g. order flow) rather than to fundamentals. This enables them to infer more information from past trades. I show that agents trading on such information, typically high-frequency traders, decrease the likelihood of short-lived mispricings by trading against price pressure. In the long-run however, such countervailing speculation amounts to signal-jamming, slowing down price discovery. These traders insure the market against short-run crashes by "catching falling knives". Higher adverse selection and slower convergence form the "premium" paid by other market participants
Optimal Supervisory Architecture and Financial Integration in a Banking Union
No full textBoth in the United States and in the Euro Area, bank supervision is the joint responsibility of local and central supervisors. I study a model in which local supervisors do not internalize as many externalities as a central supervisor. Local supervisors are more lenient, but banks also have weaker incentives to hide information from them. These two forces can make a joint supervisory architecture optimal, with more weight put on centralized supervision when cross-border externalities are larger. Conversely, more centralized supervision endogenously encourages banks to integrate more cross-border. Due to this complementarity, the economy can be trapped in an equilibrium with both too little central supervision and too little financial integration, when a superior equilibrium would be achievable
Optimal supervisory architecture and financial integration in a banking union
No full textBoth in the United States and in the Euro area, bank supervision is the joint responsibility of local and central/federal supervisors. I study how such a system can optimally balance the lower inspection costs of local supervisors with the ability of the central level to internalize cross-border or interstate externalities. The model predicts that centralised supervision endogenously increases market integration and cross-border externalities, further strengthening the need for centralised supervision. This complementarity implies that, for some parameterizations of the model, the economy can be trapped in a local supervision equilibrium with low supervision and integration. In such a case, the forward-looking introduction of a centralized supervisory architecture achieves a superior equilibrium
Rational blinders: strategic selection of risk models and bank capital regulation
No full textThe regulatory use of banks' internal models aims at making capital requirements more accurate and reducing regulatory arbitrage, but may also give banks incentives to choose their risk models strategically. Current policy answers to this problem include the use of risk-weight floors and leverage ratios. I show that banks for which those are binding reduce their credit supply, which drives interest rates up, invites other banks to adopt optimistic models and possibly increases aggregate risk in the banking sector. Instead, the strategic use of risk models can be avoided by imposing penalties on banks with low risk-weights when they suffer abnormal losses or bailing out defaulting banks that truthfully reported high risk measures. If such selective bail-outs are not desirable, second-best capital requirements still rely on internal models, but less than in the first-best

Asset Dissemination Through Dealer Markets
No full textMany financial assets are disseminated to final investors via chains of over-the-counter transactions between dealers. We model such an intermediation process as a game with successive take-it-or-leave-it offers: A dealer buys several units of an asset, and can sell some of them to his customers or to a second dealer, who can sell to his customers or to a third dealer, and so on. In equilibrium, the asset is disseminated through a sequence of OTC transactions between dealers. The number of dealers involved, the inventories they keep, and the prices and quantities they offer are endogenously determined. Our model gives a framework to analyze how assets are disseminated through OTC markets, how liquidity evolves along a sequence of transactions, and varies across different sequences of different lengths
Cash Providers: Asset Dissemination over Intermediation Chains
No full textMany financial assets are disseminated to final investors via chains of over-the-counter transactions between intermediaries (investors or dealers). We build a model where an agent buying some units of the asset can offer to sell part of them to an OTC partner. Intermediation chains are endogenously formed and impact the asset's market liquidity, its issuance, and who ultimately holds the asset. An increase in the intermediaries' funding liquidity (e.g. a lower haircut on the asset) makes intermediation less necessary but also makes it cheaper to issue the asset, increasing the total volume to be distributed and the number of intermediaries and agents holding the asset. We derive implications on liquidity in OTC markets, the dissemination of ''toxic" assets and the collateral policy of central banks and CCPs
