Price Discovery for Derivatives
We consider price discovery across derivative markets in a general framework where an agent has private information regarding state probabilities and trades state-contingent claims. In an equivalent options formulation, the informed agent has private information regarding arbitrary aspects of an underlying asset's payoff distribution and trades option portfolios. We characterize the informed demand, price impact, and information efficiency of prices. The informed demand formula prescribes option strategies for trading on any given aspect of the underlying payoff, thereby rationalizing and extending those used in practice for e.g. volatility trading.

Derivatives pricing using signature payoffs
We introduce signature payoffs, a family of path-dependent derivatives that are given in terms of the signature of the price path of the underlying asset. We show that these derivatives are dense in the space of continuo…
Cross impact in derivative markets
Trading a financial asset pushes its price as well as the prices of other assets, a phenomenon known as cross-impact. The empirical estimation of this effect on complex financial instruments, such as derivatives, is an o…
Generic Forward Curve Dynamics for Commodity Derivatives
This article presents a generic framework for modeling the dynamics of forward curves in commodity market as commodity derivatives are typically traded by futures or forwards. We have theoretically demonstrated that comm…
Model-free price bounds under dynamic option trading
In this paper we extend discrete time semi-static trading strategies by also allowing for dynamic trading in a finite amount of options, and we study the consequences for the model-independent super-replication prices of…
Determination of the L\'evy Exponent in Asset Pricing Models
We consider the problem of determining the L\'evy exponent in a L\'evy model for asset prices given the price data of derivatives. The model, formulated under the real-world measure $\mathbb P$, consists of a pricing ker…
