A fast, accurate method for value-at-risk and expected shortfall
A fast method is developed for value-at-risk and expected shortfall prediction for univariate asset return time series exhibiting leptokurtosis, asymmetry and conditional heteroskedasticity. It is based on a GARCH-type process driven by noncentral t innovations. While the method involves the use of several shortcuts for speed, it performs admirably in terms of accuracy and actually...

Expected utility preferences for contingent claims and lotteries
In Arrow’s seminal analysis of optimal risk bearing in which he introduced contingent claim securities, he assumed preferences were representable by a state independent Expected Utility function. Although the classic contingent claim setting assumes agents choose over contingent consumption vectors conditioned on a fixed set of probabilities, later work on information economics...

In order to underline this significance, Tom L. Beauchamp and James F. Childress base the principles in the common morality, i.e. they claim that...

Liquidity creation in the nineteenth century: The role of the clearing houses
This working paper reports the preliminary results of an effort to analyse under what conditions liquidity can be created in an historic context setting. 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 provides evidence that demand for equity index options has predictive power for
future volatility beyond current and lagged volatility in publicly available data. The predictive power increases prior to macroeconomic announcements and exhibits a positive relation with investor uncertainty about macroeconomic news. Straddle positions that trade on the volatility...

Tail risk, capital requirements and the internal agency problem in banks
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...

Detecting informed trading activities in the options markets
We develop statistical methods to detect informed trading in options markets. We apply these methods to 31 companies from various sectors over 14 years analyzing approximately 9.6 million option prices. 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...

Discussion of Presbitero, Udell and Zazzaro

PUZ start from the quarterly editions of a monthly survey of about 3,800 Italian manufacturing firms (by ISAE, now ISTAT) to...

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...
