We argue that post-crisis banking regulations pass through from regulated institutions to unregulated arbitrageurs. We document that, once post-crisis regulations bind post 2014, hedge funds use a larger number of prime brokers and diversify away from GSIB-affiliated prime brokers, and that the...

We propose an asset pricing factor model constructed with semi-parametric characteristics-based mispricing and factor loading functions. This model captures common movements of stock excess returns and includes a two-layer network of arbitrage returns interconnected by security-specific...

This paper is an attempt to study fundamentally the valuation of insurance contracts. We start from the observation that insurance contracts are inherently linked to financial markets, be it via interest rates, or – as in hybrid products, equity-linked life insurance and variable annuities –...

We fully characterize the absence of Butterfly arbitrage in the SVI formula for implied total variance proposed by Gatheral in 2004. The main ingredient is an intermediary characterization of the necessary condition for no arbitrage obtained for any model by Fukasawa in 2012 that the inverse...

We develop a framework for computing the total valuation adjustment (XVA) of a European claim accounting for funding costs, counterparty credit risk, and collateralization. Based on no-arbitrage arguments, we derive backward stochastic differential equations (BSDEs) associated with the...

We analyze a model of anomaly discovery and test its new predictions on both asset prices and arbitrageurs' trading. Consistent with existing evidence, the discovery of an anomaly reduces its magnitude and increases its correlation with other anomalies. Using 99 anomalies, we test the new...

Arbitrageurs with a short investment horizon gain from accelerating price discoveryby advertising their private information. However, advertising many assets mayoverload investors' attention, reducing the number of informed traders per assetand slowing price discovery. So arbitrageurs optimally...

We investigate the effects of arbitrageurs' behavioral biases on cross-sectional equity returns. We find evidence that profits of equity market neutral hedge portfolios are positively affected by overconfidence, the effects of which are not subsequently reversed. Further we discover that signals...

Slow-moving capital cannot fully explain the 2005 and 2008 arbitrage crashes in theconvertible bond market. Faced with depressed convertible bond prices implying negative option values, some investors continued to buy strictly dominated straight bonds from the same issuers. This finding suggests...
