Competition between DEXs through Dynamic Fees
Leonardo Baggiani, Martin Herdegen, Leandro Sanchez-Betancourt
We find an approximate Nash equilibrium in a game between decentralized exchanges (DEXs) that compete for order flow by setting dynamic trading fees. We characterize the equilibriu…
Solving Linear-Quadratic Stochastic Control Problems with Signatures
Alif Aqsha, Peter Bank, Leandro Sánchez-Betancourt
We study a signature-driven numerical scheme to solve multi-dimensional linear-quadratic (LQ) stochastic control problems. Using that linear signature functionals are dense in the…
Trading in CEXs and DEXs with Priority Fees and Stochastic Delays
Philippe Bergault, Yadh Hafsi, Leandro Sánchez-Betancourt
We develop a mixed control framework that combines absolutely continuous controls with impulse interventions subject to stochastic execution delays. The model extends current impul…
Optimal Exit Time for Liquidity Providers in Automated Market Makers
Philippe Bergault, Sébastien Bieber, Leandro Sánchez-Betancourt
We study the problem of optimal liquidity withdrawal for a representative liquidity provider (LP) in an automated market maker (AMM). LPs earn fees from trading activity but are ex…
Martingale Posterior Neural Networks for Fast Sequential Decision Making
Gerardo Duran-Martin, Leandro Sánchez-Betancourt, Álvaro Cartea +1
We introduce scalable algorithms for online learning of neural network parameters and Bayesian sequential decision making. Unlike classical Bayesian neural networks, which induce p…
Equilibrium Reward for Liquidity Providers in Automated Market Makers
Alif Aqsha, Philippe Bergault, Leandro Sánchez-Betancourt
We find the equilibrium contract that an automated market maker (AMM) offers to their strategic liquidity providers (LPs) in order to maximize the order flow that gets processed by…
