The Cost of Misspecifying Price Impact

Natascha Hey, Jean-Philippe Bouchaud, Iacopo Mastromatteo +2

Portfolio managers' orders trade off return and trading cost predictions. Return predictions rely on alpha models, whereas price impact models quantify trading costs. This paper st…

Closed-Loop Nash Competition for Liquidity

Alessandro Micheli, Johannes Muhle-Karbe, Eyal Neuman

We study a multi-player stochastic differential game, where agents interact through their joint price impact on an asset that they trade to exploit a common trading signal. In this…

Liquidity Provision with Adverse Selection and Inventory Costs

Martin Herdegen, Johannes Muhle-Karbe, Florian Stebegg

We study one-shot Nash competition between an arbitrary number of identical dealers that compete for the order flow of a client. The client trades either because of proprietary inf…

An Equilibrium Model for the Cross-Section of Liquidity Premia

Johannes Muhle-Karbe, Xiaofei Shi, Chen Yang

We study a risk-sharing economy where an arbitrary number of heterogenous agents trades an arbitrary number of risky assets subject to quadratic transaction costs. For linear state…

Asset Pricing with General Transaction Costs: Theory and Numerics

Lukas Gonon, Johannes Muhle-Karbe, Xiaofei Shi

We study risk-sharing equilibria with general convex costs on the agents' trading rates. For an infinite-horizon model with linear state dynamics and exogenous volatilities, we pro…
