We argue exogenous random treatment is insufficient for valid inference regarding the sign and magnitude of causal effects in dynamic environments. In such settings, treatment responses must be understood as contingent upon the typically unmodeled policy generating process. With binary...

We determine optimal security design and retention of asset-backed securities by a privately informed issuer with positive NPV uses for immediate cash. In canonical models, investors revert to prior beliefs if issuers pool at zero-retentions (originate-to-distribute), and separating equilibria...

We examine screening incentives, welfare and the case for mandatory skin-in-the-game. Ex ante banks can screen, using interim private information to choose retentions and structuring. Ex post speculators trade with rational hedging investors. Absent regulation, there is a separating equilibrium...

Since World War II, direct stock ownership by households has largely been replaced by indirect stock ownership by financial institutions. We argue that tax policy is the driving force. Using long time-series from eight countries, we show that the fraction of household ownership decreases with...

Intuition suggests that firms with higher cash holdings are safer and should have lower credit spreads. Yet empirically, the correlation between cash and spreads is robustly positive and higher for lower credit ratings. This puzzling finding can be explained by the precautionary motive for...

Repo auctions are multiunit auctions regularly used by central banks to inject liquidity into the banking sector. Banks have a fundamental need to participate because they have to satisfy reserve requirements. Superficially, repo auctions resemble treasury auctions; the format and rules are...
