Bridging Schrödinger and Bass: A Semimartingale Optimal Transport Problem with Diffusion Control

Pierre Henry-Labordere, Grégoire Loeper, Othmane Mazhar +2

We study a semimartingale optimal transport problem interpolating between the Schrödinger bridge and the stretched Brownian motion associated with the Bass solution of the Skorokho…

The Subtle Interplay between Square-root Impact, Order Imbalance & Volatility II: An Artificial Market Generator

Guillaume Maitrier, Grégoire Loeper, Jean-Philippe Bouchaud

This work extends and complements our previous theoretical paper on the subtle interplay between impact, order flow and volatility. In the present paper, we generate synthetic mark…

Generating realistic metaorders from public data

Guillaume Maitrier, Grégoire Loeper, Jean-Philippe Bouchaud

This paper introduces a novel algorithm for generating realistic metaorders from public trade data, addressing a longstanding challenge in price impact research that has traditiona…

The "double" square-root law: Evidence for the mechanical origin of market impact using Tokyo Stock Exchange data

Guillaume Maitrier, Grégoire Loeper, Kiyoshi Kanazawa +1

Understanding the impact of trades on prices is a crucial question for both academic research and industry practice. It is well established that impact follows a square-root impact…

From entropic transport to martingale transport, and applications to model calibration

Jean-David Benamou, Guillaume Chazareix, Grégoire Loeper

We propose a discrete time formulation of the semi-martingale optimal transport problem based on multi-marginal entropic transport. This approach offers a new way to formulate and…

Entropic Semi-Martingale Optimal Transport

Jean-David Benamou, Guillaume Chazareix, Marc Hoffmann +2

Entropic Optimal Transport (EOT), also referred to as the Schrödinger problem, seeks to find a random processes with prescribed initial/final marginals and with minimal relative en…
