Equilibrium under TWAP trading with quadratic transaction costs

Mathematical Finance 2020-08-05 v2 Trading and Market Microstructure

Abstract

We study how transaction cost affects to the equilibrium return and optimal stock holdings in equilibrium. To this end, we develop a continuous-time risk-sharing model where heterogenous agents trade toward terminal target holdings subject to a quadratic transaction cost. The equilibrium stock holdings and trading rate under transaction cost are characterized by a unique solution to a forward-backward stochastic differential equation (FBSDE). The equilibrium return is also characterized as the unique solution of a system of coupled but linear FBSDEs.

I find serious fundamental mistakes, so I would like to withdraw the paper. I will work again and upload later
