<北京大学数量经济与数理金融教育部重点实验室>学术报告——Optimal Dynamic Asset Allocation with Transaction Costs: The Role of Hedging Demands

Abstract: A number of papers have solved for the optimal dynamic portfolio strategy when expected returns are time-varying and trading is costly, but only for agents with myopic utility. Non-myopic agents benefit from hedging against shocks to the investment opportunity set even when transaction costs are zero (Merton, 1969, 1971). In this paper, we propose a solution to the dynamic portfolio allocation problem for non-myopic agents faced with a stochastic investment opportunity set, when trading is costly. We show that the agent's optimal policy is to trade toward an "aim" portfolio, the makeup of which depends both on transaction costs and on each asset's correlation with changes in the investment opportunity set. The speed at which the agent should trade towards the aim portfolio depends both on the shock's persistence and on the extent to which the shock can be effectively hedged.
