Codice QDD 138 Titolo Optimal impulse control of a portfolio with a fixed transaction cost Data 2012-11-12 Autore/i Baccarin, S; Marazzina, D. Link Download full text Abstract The aim of this work is to investigate a portfolio optimization problem in presence of fixed transaction costs. We consider an economy with two assets, one risky and one risk-free, and an agent fully described by its power utility function. We show how fixed transaction costs influence the agent s behavior, showing when it is optimal to recalibrate his/her portfolio, paying the transaction costs.
