A hot-potato game under transient price impact and some effects of a transaction tax

  author={A. Schied and Tao Zhang},
  journal={arXiv: Trading and Market Microstructure},
Building on observations by Sch\"oneborn (2008), we consider a Nash equilibrium between two high-frequency traders in a simple market impact model with transient price impact and additional quadratic transaction costs. We show that for small transaction costs the high-frequency traders engage in a "hot-potato game", in which the same asset position is sold back and forth. We then identify a critical value for the size of the transaction costs above which all oscillations disappear and… Expand

Nash Equilibria in Market Impact Models : Differential Game, Transient Price Impact and Transaction Costs
Market impact is the effect caused by transactions that can move asset prices. Nash equilibria describe an optimal state for the players in a non-cooperative game. In this thesis, we combine theseExpand
A State‐Constrained Differential Game Arising in Optimal Portfolio Liquidation
We consider $n$ risk-averse agents who compete for liquidity in an Almgren--Chriss market impact model. Mathematically, this situation can be described by a Nash equilibrium for a certainExpand
An Optimal Execution Problem with a Geometric Ornstein-Uhlenbeck Price Process
We study an optimal execution problem in the presence of market impact where the security price follows a geometric Ornstein-Uhlenbeck process, which implies the mean-reverting property, and showExpand
Multivariate Transient Price Impact and Matrix-Valued Positive Definite Functions
A model for linear transient price impact for multiple assets that takes cross-asset impact into account and single out properties that need to be imposed on the decay kernel so that the model admits well-behaved optimal trade execution strategies. Expand
An Optimal Execution Problem in the Volume-Dependent Almgren-Chriss Model
In this study, we introduce an explicit trading-volume process into the Almgren--Chriss model, which is a standard model for optimal execution. We propose a penalization method for deriving aExpand

This study introduces an explicit trading-volume process into the Almgren-Chriss model, which is a standard model for optimal execution and derive a second-order asymptotic expansion of the optimal strategy and verify its accuracy numerically. Expand
Effets de rétroaction en finance : applications à l'exécution optimaleet aux modèles de volatilité
Dans cette these, nous considerons deux types d'application des effets de retroaction en finance. Ces effets entrent en jeu quand des participants de marche executent des sequences de transactions ouExpand
Theoretical and Numerical Analysis of an Optimal Execution Problem with Uncertain Market Impact
This paper is a continuation of Ishitani and Kato (2015), in which we derived a continuous-time value function corresponding to an optimal execution problem with uncertain market impact as the limitExpand


Price Manipulation and Quasi-Arbitrage
In an environment where trading volume affects security prices and where prices are uncertain when trades are submitted, quasi-arbitrage is the availability of a series of trades that generateExpand
Episodic Liquidity Crises: Cooperative and Predatory Trading
We describe how episodic illiquidity arises from a breakdown in cooperation between market participants. We first solve a one-period trading game in continuous-time, using an asset pricing equationExpand
Optimal Trade Execution and Absence of Price Manipulations in Limit Order Book Models
The main results show that, under general conditions on the shape function of the limit order book, placing deterministic trade sizes at trading dates that are homogeneously spaced is optimal within a large class of adaptive strategies with arbitrary trading dates. Expand
Order Book Resilience, Price Manipulation, and the Positive Portfolio Problem
The viability of a market impact model is usually considered to be equivalent to the absence of price manipulation strategies. By analyzing a model with linear instantaneous, transient, and permanentExpand
Constrained portfolio liquidation in a limit order book model
The main results solve the problem of minimizing the expected liquidity costs within a given convex set of predictable trading strategies by reducing it to a deterministic optimization problem. Expand
Market Microstructure knowledge needed to control an intra-day trading process
A lot of academic and theoretical works have been dedicated to optimal liquidation of large orders these last twenty years. The optimal split of an order through time (“optimal trade scheduling”) andExpand
The Flash Crash: The Impact of High Frequency Trading on an Electronic Market
We use E-mini S&P 500 futures market audit-trail data to compare the trading of High Frequency Traders and other traders during the Flash Crash of May 6, 2010 with the three prior trading days. OnExpand
Optimal control of execution costs
We derive dynamic optimal trading strategies that minimize the expected cost of trading a large block of equity over a fixed time horizon. Specifically, given a fixed block SM of shares to beExpand
No-dynamic-arbitrage and market impact
Starting from a no-dynamic-arbitrage principle that imposes that trading costs should be non-negative on average and a simple model for the evolution of market prices, we demonstrate a relationshipExpand
Fluctuations and response in financial markets: the subtle nature of ‘random’ price changes
Using trades and quotes data from the Paris stock market, we show that the random walk nature of traded prices results from a very delilcated interplay between two opposite tendencies: long-rangeExpand
