Liquidity creation in the nineteenth century: The role of the clearing houses

Starting point is the notion made by Dang, Gorton, and Holmstrom (2012) that symmetric ignorance can create liquidity in money markets under certain circumstances. The authors take as an example the New York clearing house (NYCH)…

The information content of option demand

This paper combines the concept of market sidedness with excess option demand (changes in open interest) to solve the empirical challenge of separating directional from uninformed trading motives in widely available, unsigned options data. Our measure of options market sidedness persistently predicts the sign and strength of stock returns. Trading strategies conditional on the…

This paper shows how to design incentive-based capital requirements that would prevent the bank from manufacturing tail risk. In the model, the senior bank manager may have incentives to engage in tail risk. Bank shareholders can prevent the manager from taking on tail risk via the optimal incentive compensation contract. To induce shareholders to implement this contract, capital…

We find that option informed trading tends to cluster prior to certain events, takes place more in put than call options, generates easily large gains exceeding millions,is not…

Are integrative or distributive outcomes more satisfactory? The effects of interest-based versus value-based issues on negotiator satisfaction Negotiator satisfaction

Negotiation research usually distinguishes between integrative and distributive outcomes. Integrative outcomes satisfy the negotiation parties' most important interests (by trading off less important for more important issues). In contrast, distributive outcomes require negotiators to give up their most important interests (as they make concessions on both less and more…

Hazardous times for monetary policy: What do twenty-three million bank loans say about the effects of monetary policy on credit risk?

We identify the effects of monetary policy on bank risk-taking with an exhaustive credit register containing loan contracts and applications since 1984. We separate the compositional changes in the credit supply from the demand, firm and bank balance-sheet channels by accounting for both observed and unobserved time-varying firm and bank heterogeneity through time*firm and time*bank…

Optimal dividend policy with random interest rates

Several recent papers have studied the impact of macroeconomic shocks on the financial policies of firms. However, they only consider the case where these macroeconomic shocks affect the profitability of firms but not the financial markets conditions. We study the polar case where the profitability of firms is stationary, but interest rates and issuance costs are governed by an…

Rethinking the regulatory treatment of securitization

In a model where banks play an active role in monitoring borrowers, we analyze the impact of securitization on bankers’ incentives across different macroeconomic scenarios. We show that securitization can be part of the optimal financing scheme for banks, provided banks retain an equity tranche in the sold loans to maintain proper incentives. In economic downturns however…

Banks and bonds: the impact of bank loan announcements on bond and equity prices

We study the effect of bank loan announcements on the borrowing firms' bond and equity prices. Our sample consists of 896 loan deals signed between 1997 to 2003 involving 364 different US firms. We report the first comprehensive evidence that also firm bond prices react to bank loan announcements. Using a two-day event window, we find significant abnormal bond credit spreads…

Can utility optimization explain the demand for structured investment products?

In this paper, we first show that for classical rational investors with correct beliefs and constant absolute or constant relative risk aversion, the utility gains from structured products over and above a portfolio consisting of the risk-free asset and the market portfolio are typically much smaller than their fees. This result holds irrespectively of whether the investors can…

Sacred values: Trade-off type matters

Previous psychological investigations revealed that sacred values (SVs; the belief that certain values are nonsubstitutable and may not be traded off, in particular, against secular economic values) modulates moral decision making depending on the type of SV infringement involved. Extending this research, we compared neurofunctional correlates determined from fMRI measurements during…

Reinsurance or Securitization: The Case of Natural Catastrophe Risk

We investigate the suitability of securitization as an alternative to reinsurance for the purpose of transferring natural catastrophe risk. We characterize the conditions under which one or the other form of risk transfer dominates using a setting in which reinsurers and traders in financial markets produce costly information about catastrophes. Such information is useful to insurers…
